FC-1 fighter plane flight control system including fax and traditional two kind of patterns
The Fierce Dragon FC-1 fighter plane installs domestic product electronic countermeasure and jamming system
　　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.
