J-10B Performance Analysis
J-10B testing machine latest photos of gray paint has been out. J-10B should have several states, we now see one of them. This type may be related with the export model of Pakistan, but it is our J-10B.
1: Significant changes
J-10B looks the most obvious change is the inlet to DSI ("clam" style) (non-inlet boundary layer separated Road) inlet.
With the original adjustable inlet dual 3 compared to wave system, DSI can play to reduce weight, increase stealth capability to increase the intake efficiency, reduce costs and increase reliability function. As a model and all-area air fighter, J-10 has a relatively high speed at height requirements, for the use of a complex wave system of binary 3 adjustable inlet, it has a higher than SU-27, F- 16 more excellent high-altitude high-speed capabilities, as is J-10 has just made public a statement that he was one of the reasons 3.5 generation fighter. But such large weight of the inlet structure; order to strengthen the structure of the additional six ribs on the role of stealth damage greatly criticized by unscrupulous people, while the 3rd generation, 3.5 generation of aircraft ribs are common. DSI intake inlet and lighter than conventional, compared to the original inlet, greatly reduced structural weight. J-10 SU-27 has good than a lot of maneuverability, the only regret is that the engine thrust is not big enough reasons, the thrust to weight ratio, stability has been the subject of suspicion hovering ability. DSI will undoubtedly increase the adoption of J-10B thrust-weight ratio, stability, performance, and the whole plane circled mobility plays a significant role. Plus benefits in other areas, DSI performance on the J-10B obvious effect. DSI as a 4-generation technology, the FC-1 when he first appeared on the altar in the army caused a huge stir in the J-10B is also the unanimous choice on the possible applications.
J-10B is another significant change in its nose radome. The nose radome combination with backward inclined to slash office, learned that that its equipment was AESA (active phased array radar).
J-10 is the 1473 original equipment flat slot array radar, is the 3rd generation technology; AESA is four-generation technology. AESA longer detection range, higher accuracy, reflecting the faster, more capable handling multi-objective, more reliable; have more updated use function; adopting some technology, stealth stronger. AESA AESA's use of the Chinese fighter radar in the area and the European stand on the same starting line. Under the photos show, J-10B radar diameter smaller than the original, this may be due to the use of AESA, it do not then the diameter of the original so great. Smaller diameter reduces wind resistance head, help to improve the flight speed. Another change is the J-10B from the conical head into a flat circle, to play on the air inlet before entering the pre-compression. Head slightly downward, to improve the vision.
Nose droop angle of attack increased, improved mobility.
Photos from the front view, J-10B switched to diffraction HUD, the installation of the IRST (optical detection system).
Diffraction HUD, also known as wide-angle holographic HUD. Compared with the refraction HUD, its larger field of view (with help of weapons targeting and night flying), location perspective rate, a higher reflectivity characters.
Passive optical detection technology is the trend of the early 21st century, both the Air Force or the Navy also. As passive detection to avoid exposure to the whereabouts of their firing radar and avoid arouse his suspicions. The early 21st century infrared detection devices must not only be able to Discovery location, but also to conduct thermal imaging, in addition to increasing the performance of enemy detection accuracy, increase the accuracy of infrared missiles, fighter planes have also made an unexpected self-defense capabilities - to intercept air to air missile. In fact the photoelectric detection device said to be the trend of the early 21st century, a friend who is very sorry the north - Russia - the early 1980s, SU-27 and MiG-29, the photoelectric detector has become the necessary equipment, the West until the new generation of fighters (the West 4th generation) began to use, it might be the former East Germany after German reunification MiG-29 brought to Europe so that attention to the impact of the technology. Installation of this type is said IRST "60KM Department in tracking stealth aircraft, 30KM to 50KM away with identification on the enemy, show enemy formation, the number of statistical enemy aircraft, missiles to provide guidance on the ability"; if the allegations are true , that is the world's advanced level.
As can be seen from the photos, J-10B may use the composite rack.
Composite rack mounted with the same mount point more than pieces of weapons and the ability to significantly increase the number of weapons mounted on the improvement of ground attack role is great. J-10 as an air-superiority fighter, although it has a strong potential for ground attack, but the past performance is not obvious. J-10B's use of composite pylons that its formal conversion to multi-purpose fighter.
It is reported that J-10B machine increases the fuel tank, increasing the wing area, there are claims that an increase of 4%.
J-10B, another significant change is the vertical tail to install an electronic module. This shows that have greatly strengthened its electronic warfare capability.
The other is the horizontal tail cutting tip, airspeed cancellation changed.F-10B cut tail tip, ventral fin cutting tip, useful to improve the aircraft's high-speed performance. Not much here to do comments.
Has been questioned before the J-10B "DSI inlet" of the change, fearing it will affect the J-10B high-speed performance, it now appears that due to ignorance and excess. J-10B's "DSI Inlet" will be designed to be placed on the 2.0MH, canard fly-in the 4th generation systems excellent balance of high / low speed performance. Actual flight test results show that, "J-10B high-altitude high-speed better than the J-10A, mobile quality and better", its full flight envelope (0 ~ 2.3MH) stages are better acceleration performance and stable hover performance improvement is gratifying.
2. Stealth Performance
Alleged use of integrated stealth technology, J-10B radar reflection area of less than the J-10A an order of magnitude. In this case, the stealth performance and double the wind (both in Europe and most advanced fighter) is similar to radar reflection area of less than 1.
3. Avionics and weapons systems
Although the J-10B enhance aerodynamic performance of the other people surprise, but some people say, J-10B real highlight is its avionics and weapons upgrade.
J-10B, as the fourth generation of fighter avionics test aircraft, the avionics system is pretty good. ” Someone said: "In fact, 10B on the AESA is not even worth very excited - the other avionics and significance of the pace of change is much greater than one kind of aircraft can be loaded in the AESA. 10B avionics architecture and performance of a kind of degree, with reference to the Po columns F-22 standards, such as an independent flight control, fire control replaced by a new generation of integrated CIP (Common Signal Processor). SU-35 is closer to Western standards, natural more clearly. But now the situation seems, SU-35 is the standard Western-type levels of the three generations later. "
According to the now popular aircraft performance evaluation formula:
Machine performance = speed × mobility (square) × Avionics (cubic) × weapons (four square)
J-10B overall avionics upgrade (on behalf of the nearly 3.5 to nearly 4 generations), will bring his quality to enhance combat capability.
Well weapons systems, in addition to precision strikes all kinds of ammunition, four generations in the remote, short-range air to air missile should be enough. Four generations of fighting to be heard before the missile to equip the rumors.
4. Future development
Someone Language: In fact, the modified J10 will always exist, one increased (re-4 (5) pre-service) needs of the Air Force air power, and second, to share part of the re-4 (5) the risk of the development, re-4 (5 ) is an independent research funding, J10 of the modification is independent funding, J10 of the modification to the 4th generation (5) approaches, share the burden of re-4 (5) the risks of scientific research and experiment on the re-4 (5) development of play multiplier effect, improved version of the ultimate vest will spend a standard 4-generation (5) in the single machine supporting avionics.
5.Conclusion
With the J-10B, we do not envy double the In addition to the engine. 。 . 。 .
Is uncertain whether the current use of the J-10B "Flying fire push" integration of technology, but the J-10B will use.
The J-10B is now clear experimental aircraft engines are installed or the original AL-31FN, may be improved with a greater thrust. Planned J-10B standard configuration should be "too by changing the" engine, thrust 142 KN.If the J-10B is equipped with a greater thrust of the "Taihang change." 。 . 。 .
Unfortunately, even the "Taihang", and still is problematic. "Taihang change", to drag the progress of the.
Of course, we You Liangshou preparation, the Russian AL-31FN M1, or is said that chickens lay eggs in Russia by the 99M2, can meet the requirements. But the engine also on large-scale imports of you constantly.
We only hope the dawn companies hope they can learn, practical and strict, to progress to catch up to.
