a close up picture . . . . .

If u r considering the above . . . . . than man its gun . . . . Of JFT

and how many time we have to tell u people . . . .

But yes opposite to it, they can put a hard point for targeting pod . . . . . .

i always wondered where the gun was!

STEALTHLIKE JFT BLK2 FORWARD FUSELAGE MIGHT BE CLOSER TO REALITY

It has a smaller diamond shaped nose section (as compared to the J-20 diamond nose, still bigger than current JFT nose) and slightly modified DSI intakes, this indicates that frontal RCS has been reduced dramatically and my guess is it should be less than Gripen NG. You can also check huitong's page, JFT section, which is always an excellent read on Chinese weapon systems

FC-1/JF-17 Thunder Dragon/Thunder
The latest rumor (March 2011) suggested that an improved version with a stealth optimized forward fuselage is being developed.

modified frontal fuselage *concepts -- maybe we will see something in blk2 , now with the news of chinese testing a modified fuselage for jft

 

[Manticore]

I don't know but it seems most people here don't really follow developments, or they forget or they simply choose to ignore:

1. Klimov have already made public that the RD-93 is available with 96kN max output.
2. We already know and expect further JF-17 developments to reduce the basic weight of the plane.

The above two say the JF-17 will be having a high TWR soon.

There is no immediate need to get the WS-13 considering ,

1. The training required for ground crew.
2. The WS-13 will be different is behaviour to the RD-93 so flight control systems and tactics will not be 100% transferable. FCS will need reprogramming and validated.
3. Pilots will need to re-familiarise with the aircraft's behaviour.
4. WS-13 need to mature!!!

Finally, I have been looking at the surrent air campaign in Libya. The weapons loads have generally not been much more than 4-6 munitions and 3 external fuel tanks (EFTs). We have seen the JF-17 with 2 x SRAAMs, 4 x Mk-82 bombs and 3 x EFTs!! I think it terms of lead it is pretty compariable/not inferior to what NATO planes are doing in Libya. Looks like a lots of the "IMPRESSIVE WARLOADS" fotos we see and fantasise about are really not practical but a marketing gimic.

Unless you are really going to do some type of carpet bombing, latest smart (planning) wars with smart (guided) weapons rely on pinpoint accuracy on selected targets. We will not be expecting a lot of B-52 type runs with bomb bay spewing out dozens of bombs. The JF-17 with 12 FT-series bombs of say 100kg weight (1,200kg) will do a fair bit of damage. Weapons (and yes everything else) is getting more potent while being smaller and lighter).

some nice points..

I may be wrong but lets look at this picture is that a targeting pod.

 

[Tempest II]

I may be wrong but lets look at this picture is that a targeting pod.

You right - I stand corrected. They can carry and USE the pods but apparently they RAF have a limited number of Tiffy pilots who can use the pods. Source: LIBYA: RAF Typhoon hits fresh target, with help from Tornado

The decision to use targeting services provided by the Tornado GR4 stems from a shortage of adequately trained Typhoon pilots, as illustrated in information published by the UK House of Commons' Public Accounts Committee on 15 April.

In evidence given to the committee on 9 March, two senior RAF officials revealed that only a fraction of the service's 48 Typhoon pilots were qualified to conduct air-to-ground missions, in line with its requirements for the fleet.

"We have eight pilots trained in the ground-attack role because that is all we need," said Air Vice Marshal Stephen Hillier, air officer commanding the RAF's 2 Group organisation. However, he added: "If we want to deploy that aircraft on an air-to-surface mission, we can do it." The UK's Typhoon force will achieve full multi-role readiness in 2018, with the bulk of the fleet to remain in use until 2030.

Infra-Red Search and Track
A Chinese infra-red search and track (IRST) system developed by the Sichuan Changhong Electric Appliance Corporation, the Type Hongguang-I (Rainbow Light-I) Electro-Optical Radar (虹光-Ⅰ型光电雷&#36798, is integrated with the J-10. It is a third generation optronics system utilising a HgCdTe focal array with imaging infra-red (ImIR) capability. Receiving its certification on 3 March 2005 and subsequently entering service with the PLAAF, the system was revealed to the public one year later at a conference on the Sichuan province of China, during which the system was demonstrated to visiting officials. Based on the limited information released, Type Hongguang-I has a maximum range of 75 km.
Although the Type Hongguang-I was designed to be lighter and more compact than similar Russian systems so that it could be fitted in the nose of J-10 while leaving enough space for a suitable radar, the current production model J-10 does not have enough space and must carry a podded version externally on one of the aircraft's hardpoints. However, recently released images show a modified variant of the J-10 with what is believed to be an IRST device fitted to the upper starboard side of the nose (see Variants). Type Hongguang-I is also designed to be compatible with China's Shenyang J-11, Shenyang J-8 and Xian JH-7 combat aircraft, as well as the Xian H-6 bomber and Sino-Pakistani JF-17 light-weight fighter.

Dragon eyeball legend: FC-1 fight flight operations electricity systems synthesis analysis

FC-1 fights the flight operations electricity system and the cabin design not only has the world first-class cabin environment, also has the world advanced level entire digitized navigation electricity system.

electronic warfare system is a FC 1 fighter aircraft's luminescent spot. According to the Pakistani initial request, the electronic warfare system only by the radar warning device, the missile approaches the warning device and the chaff jamming ball delivery management system management system constitution, we saw finally a FC 1 fighter aircraft not only greatly enhanced these three item of equipment's performance, but also additionally built the driving electronic countermeasure aircraft.

The radar warning device is a modern fighter aircraft self-defense very important method, it can tell the pilot the enemy the movement and the plan. The modern battlefield is highly the complication electromagnetic radiation battlefield, as a result of radar's popularization, in the sky will be flooding the massive various radar's electromagnetic wave in the future. The traditional radar warning device general correspondence special fire control radar, these radars concentrate in the I/G wave band, once the aiming goal, the radar will radiate the airplane unceasingly very much by the high-frequency, will carry on the high accuracy track, and the parameter which will obtain using the track carries on the weapon hypothesis and the launch control. After the 90s, a fighter aircraft will be radiated at least in the airborne each second by over a million electromagnetic pulses, if will report these radiations for the pilot, then he will be welled up without doubt magnanimous information submergence.

The advanced radar warning system will accept the electric wave frequency sweep classification, and carries on the high data rate sampling, uses the computer to carry on for the sampled signal compared to for with the analysis, seeks for fire control radar's condition code. The Modern Radar after having introduced the frequency agility technology, the radar signal scatters according to certain mathematics rule in the very narrow frequency band, this brings the very big trouble for the radar warning device's receive and the filtration signal. In order to deal with this electronic countermeasures means that the advanced radar warning equipment through will accept the electric circuit to receive the electric wave to carry on consulting, the identical electric wave different phase which the use different position will accept, judges general direction which the electric wave will originate, and all electric waves will carry on the accumulation to this direction, will carry on rightly compared to with the computer internal storage's known radar characteristic signal. Through the analysis frequency and the pulse characteristic, the radar warning device not only may know the threat the origin direction, but can also judge through the characteristic threatens the approximate function which the radar uses, may judge the threat degree through the pulse crowded degree, for instance whether to be at the fixed condition. The more advanced radar warning device may also the signal storehouse which saves through electronic intelligence's collection and the computer compared to right, distinguishes most has the threat the unit type, then infers the threat type. A FC 1 fighter aircraft uses the radar warning device has the such advanced performance, can cover 360. The entire air zone, may preserve 100~500 different models in the memory the radar characteristics, but also allows the wartime to carry on programs, may the electronic intelligence which collects most newly transform rapidly as the battle efficiency, can deal with the new threat which well appears unceasingly.

The missile approaches the warning is the new equipment which the recent for several years develop. The early similar equipment uses big field of view lens about 180 degrees to 220 degree about air zones to carry on the surveillance to the airplane rear end direction, using missile launching when will have the massive sudden change ultraviolet ray and the infrared signal, will thus provide the enemy the missile threat the warning. Will present the massive smoke and fires frequently in the battlefield, the sunlight reflects from the reflective very high white clouds, as well as will have the possibility facing the sunlight reflection to let this set of system hyperaesthesia. Usually uses the digitization signal processing to cope with this kind of false warning, its main principle will be will work continually according to the missile rocket engine period of time, and this signal's appearance will become a path continuously, the instantaneous flash and the long time stable photo source can filter continuously, will thus obtain the real missile threat.

A more advanced missile approaches the warning system to use the distributional synthesis optics aperture imaging system. Listens is a little familiar, right, this that EODAS which 135 uses with American F is somewhat similar. The distributional synthesis optics aperture imaging system replaced the beforehand point source scanning system using the image formation system, the image formation part mostly has used the indium antimonide or the silicification platinum. The former has the very good speed of response and the sensitivity, but the price is expensive; The latter has a higher clarity and the angle detail resolution, the low in price, the shortcoming is the probing range is inferior to the former, these two kind of high performance part needs the liquid nitrogen refrigeration. F 135 use 128×128 indium antimonide CCD not only to be responsible for the missile close on the warning, but must while convenient complete 360. The video frequency surveillance, was already not a pure warning equipment. A more inexpensive system will choose the thermoelectricity refrigeration the lead sulfide primary device, this kind of component price will be cheap, will radiate 1~3 microns wave bands to the missile rocket engine to be exceptionally sensitive. This wave band's infrared radiation is generally causes by the high temperature, only then the flame, the missile tail smoke and the nozzle and so on will only then produce, have the very good filtration natural radiation function; And its image formation system can also very good cope with the false warning. This kind of system often is not responsible for the peripheral environmental surveillance, some systems when optics aperture design uses the diffraction grating prism to pass to the infrared signal the infrared sensor, but the white light signal passes to has night vision ability blue silicon CCD, forms the television video signal, both supplementary, can also achieve the quite ideal performance.

The FC1 missile closes on the warning system not yet to equip on the Western three generation of fighter planes

The FC-1 missile closes on the warning system to use the distributional synthesis optics aperture imaging system, uses 4 optics apertures to complete for the level 360 degrees, the vertical ±40 cover, (a F more than 135 special-purpose foresight and special downward looking optics apertures). This set of systems not yet equip on the Western third generation fighter aircraft even third generation half fighter aircraft, France “the Rafale” has the similar system, as soon as uses the unusual image formation system, 3 aperture scanning component, the technical level abdicates slightly plans. The missile approaches the warning system to be ordinary and radar warning system crossing linking, the system will carry on the high accuracy key observation on own initiative to the radar warning direction, once discovered that will have launches missiles the sign, immediately informs missile's accurate position the pilot, even may carry on the track to the missile path, will judge missile's general distance through optics angle triangle computation. The image formation system warning system may superimpose during warning's the danger bearing video signal on the Multi-functional Displays demonstrated that is advantageous in the pilot judges. After its software further develops, but may also realize to all threat goal automatic video frequency demonstrated that avoids the miscarriage of justice which, because the artificial intelligence is insufficient and leaks sentences, simultaneously can also avoid the enemy airplanes to a great extent the sneak attack. From the Vietnam War to the Persian Gulf War, the majority air fight's results attacks the side, in the match does not know the circumstances of the matter in the situation goes well from the pilot field of vision blind spot. Will have this set of systems, the traditional blind spot will not have existed. Now also not a clear FC 1 this set of systematic development degree, uses the big area liquid-crystal display looking from its cabin, will have many video frequencies to demonstrate very obviously, may put several different region video frequencies to a monitor on concentrates the demonstration. This set of systems may strengthen fighter aircraft's survivability and close combat ability enormously, this will appear very important to the future air fight.

　　The chaff/infrared countermeasure ball release gear is also the modern fighter aircraft electronic countermeasure standard equipment. This kind starts the electronic countermeasure ball which from the Korean War uses massively, although is simple, but 40 year later today still valid. In order to resist the chaff/infrared countermeasure ball, the nearly all Modern Radar and the missile have made various improvements, but which one method doesn't have is completely effective. The however 40 year between target-oriented research development has the progress after all, it could weaken the chaff/infrared countermeasure ball enormously the potency, present's fighter aircraft already could not rely on the simple launch massive disturbance ball to escape missile's attack. Moreover the disturbance ball's delivery opportunity became very essential - - throws early, very easily and is removed by missile's antijamming circuit identify; Threw late, the missile without enough time was also deceived throws in the airplane, and the missile raided the direction and the delivery disturbance ball's best opportunity was also various. Therefore, the advanced jamming system meter equipment does not have the advanced disturbance ball, but can also closes on the warning system forecast time according to the radar warning system and the missile to judge the most appropriate opportunity, is best and pilot's circumvention movement unifies, can play the biggest interference effect. Speaking of the present technical level, did not have the missile which cannot disturb, but the concrete potency looked completely the implementation is mobile and delivery countermeasure opportunity. FC 1 this set of comprehensive navigation electricity may unify the high accuracy radar to report an emergency and to approach warning's information, the localization and so on, the automatic control disturbance ball jettison system, can display sufficiently this kind of disturbance method potency the limit.

　　The chaff ball is the passive disturbance method after all, once the missile launching, is left over is the hit probability question. How no matter the airplane does do, can only reduce this hit probability, but cannot eliminate it thoroughly. The self-defense type electronic countermeasure aircraft is one driving method, its resistance goal mainly has two: First, the fighter aircraft radar or the ground guided missile system's fire control radar, another is the present threatens day by day the serious active radar guidance advanced empty/surface-to-air missile. The self-defense type electronic countermeasure aircraft may frustrate opposite party to launch missiles the attempt effectively, with the aid in the modern electronic technology's development, a set of function complex countermeasure aircraft volume and the weight already reduced several times 10 years ago, price also inexpensive many, no longer is the heavy fighter aircraft can use. The FC-1 fighter aircraft installs the countermeasure aircraft in the vertical stabilizer peak, has forward and latter to two antennas, may cover 360. Air zone. The common electronic countermeasure mainly uses methods and so on echo repeater, angle deceit, narrow wave band blocking, the goal lies in disturbs the fighter aircraft or on guided missile system's radar, lets it be unable to obtain the correct target position information, thus destruction aiming and guidance. This will be one item facing future design, Pakistan's main simulated enemy India had already equipped the massive R 177 advanced medium range air-to-air missiles, this kind of weapon to the Palestinian Air force was one kind of serious threat. The self-defense type electronic countermeasure aircraft's design has made specially the optimization to the fighter aircraft radar and this kind of missile's detection unit, may the effective jamming current fire control radar and the missile, and has may program ability again, may through accept the new software, but carries on the promotion to the system.

　　The communication and a tactical data chain FC 1 fighter aircraft's communication system mainly depends upon two Italian Marconi Company to produce digital encrypts the UHF wave band antijamming aircraft-borne long-distance Blower, mainly uses in ground-to-air and to the place pronunciation telephone conversation. The broadcasting station uses the digital frequency modulation amplitude-modulation coding security communication, has the high-frequency frequency-hopping and jumps wide frequency antijamming ability, a broadcasting station has conforms to the American 16 data chain long-distance UHF data transmission standard ultrashort wave data chain, may transmit the tactical direction information and the tactical sharing information. Two broadcasting station's pronunciation telephone conversation serves as each other's backup, and are connected through 1553B and the duty computer, may in command system's standard tactic information fusion tactic synthesis information demonstration, or automatically in the tactical guidance map superscript row. When main line breakdown, the communication system may maintain with through the manual control broadcasting station maneuver box the ground pronunciation relation.

　　After a FC 1 official service, Singapore Airlines will perhaps use set of double data chains the long-distance communication system, will use on back's antenna and the abdomen antenna separately. If Pakistan purchases Sweden “to love the Li eye” the early-warning aircraft, will then use Italy's product; If purchases China's early-warning aircraft, will then possibly use China's communication system, regardless of which one kind will choose, they will be integrated to a set of standard union tactic information distribution system. If FC-1 can realize the tactical information through the communication system to share automatically, then fighter aircraft's battle efficiency and informationization ability will obtain the enormous enhancement. Summed up the construction by this machine present navigation electrical system has this condition completely, perhaps this was the next step software development key point.

　　The external store management and a weapon control system FC 1 fighter aircraft hangs a design is a very fine product, it defers to the Western standard completely the MIL-STD 11,760 designs and the implementation, can hang carries to conform to this standard external store, simultaneously also designed in the similar position has been possible the non-standard which adapted with the Russian weapon to hang the spot. Each hangs to use the standardized weapon connection unit, may monitor the weapon alone the external condition, carries out pilot's weapon operation, the monitoring projection condition, the monitoring weapon delivery plan, the transmission weapon to deliver the instruction, the emergency release plan, the bidirectional transmission weapon control information and so on. The connection unit and the independent external management computer are connected, and accepts the weapon task management computer's control through the 1553B data bus. Through the duty computer to the weapon condition and parameter processing, the weapon and the external store information will demonstrate on even obviously and the Multi-functional Displays.

　　Had the external store management system management system, pilot's strike weapon choice and the use becomes even more quickly, convenient, and is more reliable. Early F 116 fighter aircraft such systems, the first set of external store management system management system has not been Israel acts according to the massive war experience to make, and is purchased rapidly by the US and popularizes to all aircraft formations. This system can let the pilot reasonably a series of questions which using airplane's external weapon, automatic coordinated external involves, may liberates the pilot energy from the external weapon use and in the choice skill hesitation. The flexible auto-adapted delivery plan compared to the pilot after the manual selective jettison gallows, ponder delivery's a series of consequences and airplane's change wants relaxed and quickly many. When specially hangs carries the type complex weapon carries out some pointed very strong tasks or the random very strong duty, this set of systematic functions can be more obvious. A FC 1 system most unique place, is may also realize through this set of systems to the Eastern system's weapon with the Western weapon same task management, has enriched a FC 1 weapon applicable scope and the choice surface enormously.

FC-1 fighter plane flight control system including fax and traditional two kind of patterns

A flight control system FC 1 fighter aircraft has used a set of unique flight control system. This set of careful design's system has the high performance, the low price characteristic, both can use the fax control system's advanced flight control ability, relaxes the airplane static margin, to enhance the maneuvering performance, and retained the tradition partial hydraulic circuit and the system takes the secondary part's operation and the security backup, has met a FC 1 this kind of localization unique fighter aircraft high performance aspect need completely.

　　FC one 1 has used the mixed style fly-by-wire which set of processes simplify. In order to realize the high lifting force, the high agility, the airplane in longitudinal used the digital entire jurisdiction four redundancy to add two redundancy simulation type fly-by-wire, the control maneuvering performance most essential flap, all-moving elevator; Crosswise uses the digital two redundancy limited jurisdiction control augmentation, take the mechanical type control system as a backup, controls the rudder and the aileron. A FC 1 air operated control surface design idea is quite exquisite, has not used three generation of machine popular flaperon designs, but separates them, from the aileron function and simplified by the independence. Regarding uses the entire fax system's third generation fighter aircraft using the relaxation steady-state stability to say massively, its so-called relaxation steady-state stability mainly refers to the longitudinal static margin, all fighter aircrafts crosswise are Jinan decide. Therefore, in the complete three axle four redundancy fly-by-wire, the horizontal direction's part cannot obtain the big advantage from the fax system, on the contrary must pay 3 above control surfaces the channels and 35% above software work load.

　　Because a FC 1 fighter aircraft locates in the low price, the high performance, must use the relaxation steady-state stability for the high performance the layout, this needs a set plenary powers to limit power consumption passes on the control system, its price often surpasses several million dollars. China has a proverb: The good steel must use on the knife edge. The FC-l fighter aircraft's chief design engineer fully realizes the control system characteristic, therefore most needs to fax boldly system's longitudinal control surface and only needs to control the augmentation to be able to satisfy the request the lateral controls to come independently, then uses a group completely different control system respectively. Actually FC 1 lateral controls may also regard as are operate under a 2 redundancy fax systems control. In the normal condition, the airplane gathering flight control stick instruction and the inertial guidance system's attitude parameter, the atmospheric computer's air parameter and so on, carries on the digit in the flight control computer to be comprehensive, through the three axle inverse amplification factor actuation longitudinal movement server and the crosswise electric servo, realizes the three-axis control augmentation. The horizontal direction's mechanism control system through the traditional tension bar and the rocking shaft, realizes to the aileron and rudder's control; The control augmentation fax operation realizes through and the mechanical system coupling's compound rocking shaft, the control augmentation's operation joins through computer control's electric servo to the control channel. The leading edge maneuver wing flaps are free, under computer control automatic corresponding speeds and angle of attack balanced deflection, only when stall may the manual compulsion restoration.

　　A FC 1 control system's reliability is high, four redundancy fax system has two group breakdown security ability originally, if four groups have the problem, but may also degrade to the simulation fax control. This set of systems can satisfy the airplane to return from cruise, the landing as well as the majority of ordinary flight operation implementation; The aileron control augmentation is also same, itself has two group breakdown security structure, in addition the mechanical system is also the double redundancy, the control augmentation breaks down when may also degrade the use, similarly may satisfy the normal flight and return from cruise the landing. A FC 1 complex reliability design not greatly possibly has the opportunity in the daily use, but massively had considered the operational condition alights from a plane Rong Shang characteristic, therefore only then designed has been so complex and the firm reliable system.

　　Because FC one 1 in fact has flies controls under the computer control the completely automatic control flight, therefore coordinate radar terrain following ability and inertial navigation system's geographic information system, has the minimum altitude automatic terrain following flying ability. The former hedge-hopping flight is depends upon the pilot technology to be good, to be courageous, once meets the complex topographical condition and the request enters a lower altitude, was the manpower is unperformable. FC one 1 may by fly controls the software to form the autopilot, completes automatically under the minimum altitude condition the safe flight, has built the good foundation for it to the place attack capability's development.

　　Looking from test pilot's actual experience, this set of simplified combination flying control control system obtains the enormous success, the pilots has appreciated its mobile control, smooth flight ability and the good operation feeling. A FC 1 control handle does not look like F 116 such to use the strength coupling, but uses the displacement and the strength back coupling dual couplings, the fax systematic and control feel between mechanical system's is nearly completely consistent, the strength back coupling's feeling is more direct, control feel closer tradition fighter aircraft, but has is more dexterous and is simple.

　　A FC 1 flight control system is in an engineering masterpiece, has manifested the performance and the price organic synthesis process perfectly, realized both the high performance and inexpensive to decide the project objective.

　　From the performance, this set of systems and the F 116 three axle four redundancy fax system effectiveness not the slightest difference, but from the price, this set of systems is only F 116 system's half, is really a great pioneering work, in the worldwide scale has not seen the so careful design and the selection design proposal.

　　The advanced electron recognition system as early as in the 60s's Vietnam War, the US realized that is decided to the beyond line of sight air fight by the foe identification aspect level. But the early electronic technology is insufficient to solve this problem, the reply type identification of friend or foe system can only identify less than 30% goals, in addition the early time electronic installation reliability is low, “the house sparrow” the missile just started when the application shoots down one's own side airplane to shoot down the enemy airplanes quantity to be also more. Hereafter the United States Air Force promulgates a battle principle: Namely all airborne targets do not undergo the reliable identification and the recognition, does not permit launching attacks. This causes the massive American airplane to need to fly the goal to be able the bulk recognition distance to be able to launch attacks, has lost the beyond line of sight combat's significance. This criterion other countries is also observed by the world, has caused “the house sparrow” directly time low-spirited ending.

　　After the 80s, relies on the advanced computer technology, the foe identification technology also starts to obtain the rapidly expand, this also benefits from the entire aviation industry standardization. The advanced friend-or-foe identification still used the reply type, but this kind of reply type and the early time simple are one to one different to the cipher way, it aims at the civil channel, the military channel and the special electronic channel separately launches a large quantities of pack signal, inside even includes the enemy side responser's request signal and the code. According to carries on the analysis to the goal reply reply signal, may identify the civil flight vehicle, one's own side flight vehicle and the enemy side flight vehicle directly, as well as few cannot be recognized categories and so on flight vehicle. In may identify in the flight vehicle, the recognition system may save the storehouse according to the computer the ID code recognition storehouse to identify the type of airplane accurately, even which airplane can accurately to the concrete. To goal which cannot recognize, it according to opposite party responder reply signal type first its recognition for enemy airplanes, allied plane or unclear goal, may also through the war zone tactic information distribution, from the early warning radar place learning goal enemy and ourselves attribute, and comes out its sign row, simultaneously the record object sends out the inquiry or the identification signal, carry on its characteristic from define and save.

FC-1 fighter plane beyond line of sight ability is more precise than Indian Air force Soviet - 30MKI
The advanced friend-or-foe identification recognition method is the diversification, but may also extract in the radar signal from we radar system the target echo eigen frequency, carries on the non-cooperation recognition. The fourth generation of fight centralism application's comprehensive electronic warfare system may also through trigger the enemy electronic countermeasure or receive the enemy radar signal, through the analysis trick recognition writing up build number, then infers the goal model and the type. The advanced friend-or-foe identification is decided at the same time by own electronic processing technology level, on the other hand is also decided by the electronic intelligence collection and the analysis level. After using the advanced friend-or-foe identification, the beyond line of sight air fight basic can obtain the safeguard. American F 116 install AN/APX 1 13 systems and the AIM 1120 guided missile systems through the promotion necessary, has obtained the beyond line of sight combat's ability, this system's potency obtains in the second Persian Gulf War and the Bosnia war manifests, is the AIM 1120 missiles obtains the success the main safeguard. Carries out air superiority mission F specially 115 C fighter aircrafts, because has not carried on this aspect the improvement, therefore many air fight victories do not like by the United States Air Force F 116 obtain. Must know that the United States Air Force once died in the Persian Gulf War the F 116 pilots is must had to not to allow to participate on own initiative the air fight, this may also explain this set of system's importance from the side.

　　A FC 1 fighter aircraft has also installed the similar advanced friend-or-foe identification, but which kind of model products not the clear this set of systems are. This system and American AN/the APX 1113 4 thin-bladed knife shape antenna is different, has three pieces, the estimate operating region and the performance can be slightly inferior. According to the usual this system's working pattern, it may choose by the pilot carries out the air traffic recognition, the goal to report that the military recognition and the military distinguish safely. The air traffic recognition is the present air force intercepts the duty the most main type, on the beforehand fighter aircraft has not established the civil control recognition channel, is very difficult to the massive civil aircraft recognition, needs to send out the fighter aircraft frequently to intercept and the visual detection. Not only this will bring for the civilian target alarms, but also easy, because the pilot and commander's tense mood will have the miss shot, no matter will be Soviet Union shoots down the South Korean Boeing 747 US to shoot down Iranian A300, this will let it internationally fall into the difficult position with politics. The advanced friend-or-foe identification may the built-in all civil control goal reply code, be possible to the civil aviation target identification accurate model and the flight, and exchanges the information or the direct relation commercial aviation control center through the data chain and the Control center carries on the blank pipe distinction. All these do not need the airplane to enter in the apparent distance, may avoid the military flight enormously to the air traffic disturbance. The goal report is carries on the compulsory signal interception recognition under the target-oriented condition to the goal one way, it can all answering signal record which radiates the goal and compared to right, usually uses to intercepts the goal in the qualitative recognition, namely provides the goal nature model which for the early warning system not yet distinguishes to recognize. The military recognition and the military safe recognition are the working patterns which in time of war uses. We knew to keep secret, in time of war fighter aircraft uses the enemy and ourselves code and the frequency and the peace period are different. The military recognition and the military safe recognition are refer to have under the resistance threat condition recognition, this will let the system use some non-conventional inquiries the triggering condition, will achieve the recognition and the determination goal threat condition goal, before this kind of recognition will often use in the attack the preparation.

　　Equips the advanced friend-or-foe identification to symbolize that FC a 1 fighter aircraft will have the beyond line of sight air fight ability, this is also Pakistani Air force urgent hope ability. It that kind of simple recognition which present Indian Air force Mig 129, Mig 2 l 193, Soviet 30MKI uses adds the R 177 missile's beyond line of sight attack capabilities to be more precise than, to be more effective. This for originally will have the disparity Pakistani Air force in the fighter plane quantity and the quality to obtain the resistance in the future the quality superiority to lay the foundation.

　　A other subsystem FC 1 navigation electricity system also includes the mechanical and electrical management computer, the radio altimeter, the automatic insturment landing system, the power source management system management system division system. Mechanical and electrical management computer system airplane on all control systems and so on hydraulic pressure, mechanical and electrical transmission with sensor and computer crossing linking, may monitor these system's movement and the condition precisely, inquires the inspection project which through the simple computer faulty recording and analyzed completes many formerly needed to open examines, not only enhanced system's reliability and the maintainability, but also strengthened the airplane life greatly. Has a few words in the aircraft maintenance: The mechanical device is not easy to wear out, but easy to repair badly. Obviously the reduction will open daily examines the project to bring the great life cycle expense advantage to the airplane.

　　The radio altimeter is airplane's commonly used equipment, mainly uses in the airplane obtaining the height above airport information. The advanced radio altimeter has the wave beam to be narrow, multi-beam, continuous wave, high gain, low emissivity power characteristic, on the one hand must provide dozens of times reaches as high as a centimeter level in each second the precision, on the other hand must guarantee the electromagnetism the compatibility and low may the survey. This is mainly to avoid by the passive electronic detection system surveying, for instance Czechoslovakia “vera” a E passive electron detection positioning system. These passive systems are often covert, will give the battle airplane to bring the very big latent threat. The automatic insturment landing system and the commercial aviation third-level microwave falls the system to be very similar blindly, is uses, in the complex meteorology, does not meet under the item of unlined upper garment landing requirement to carry on the servosystem which the measuring appliance falls blindly, may enhance the airplane to the airport climatic conditions adaptiveness.

　　The power source management system management system is one of airplane's foundation equipment, particularly the modern fighter aircraft electricity consumption grows day by day, various equipment use electricity the request to be also various. The former three generations machine use the centralism power supply management system, outputs the electrical energy the generator through the distributor, the invertor and so on to transport directly to each spot. Centralized management's advantage is easy to control and the overhaul, easy to arrange radiates, the shortcoming is the different equipment needs different outputs and so on voltage, electric current, exchange or cocurrent, when the power increases the DnN certain extent easy to form disturbs mutually. Moreover, centralism arrangement once later will break down to cause the airplane all system power supply to have the problem, this will operate to the company relies on difficulty with accepts the electric power airplane comparison, the reliable request's superimposition can cause the system weight and the volume increases rapidly.

　　A FC 1 early time uses traditional the centralized power distribution management, but has presented the power failure accident in the test flight. On final total state airplane, to strengthen electrical power system's reliability, used the distributional power distribution management system management system which the fourth generation of fighter aircraft only then used - - various equipment's power distribution dispersion arrangement, the airplane power supply has only provided solely, the stable alternating current, uses the distributor which the computer controlled to the multi-channel power supplies to carry on the management and the monitor, various equipment different used electricity the request respectively to establish an independent power source switch on the equipment. This enhanced electrical power system's reliability and the power distribution flexibility greatly, when breaks down allows to close some equipment's power supply to guarantee that the main system uses electricity the demand, the security obtains the very good safeguard.

　　Uses the digital distributional power distribution power supply design also to symbolize that the Chinese fighter aircraft technology is developing the application direction unceasingly to the new generation diligently, the new electrical power distribution system's use has consummated in the FC-l early time design the last comparatively backward place, let the overall navigation electricity level surpass the Western country third generation fighter aircraft level, basic and the third generation fighter aircraft modernization improved the later ability quite.

　　FC 1 navigation electricity system's research and development manifested our country to develop the avionics system's technical level under the commercial demand, simultaneously was also our country under the trade organization to the advanced navigation electricity system design and the balanced bold attempt. Trade organization compared to me. The tradition applies the research and development system is flexible, may apply the mature new technology massively. Because fighter aircraft's research and development time is getting more and more long, the traditional contract type management already fell behind the time, the design which on the one hand FC one 1 uses on the other hand revises the route, although presented the delay and the concrete question, but obtains finally the result is very optimistic, this has prompted a new development work management route for us.

　　As soon as a FC 1 fighter aircraft develops successfully is our country fighter aircraft profession from imitates an improvement to design the milestone which an independent design completes, it symbolizes that our country already completely grasped the third generation fighter aircraft's research and the production technology, specially completely got rid in the 1980s-90s in the avionics system aspect backward passive aspect. According to the predict that China will occupy the approximately 20% about share in the future fight flight operations electricity market, FC one 1 has lasting achievements. (full text)
