Recently, Dr. Vyacheslav of Russia, deputy technical expertise in the Russian newspaper "Independent" article, the fifth generation of Chinese J-XX fighter development of the analysis, said China's 5-generation machine in order to fight against F-22, will not go to imitate Russia Test-drive road 144; Chinese designers will be headed by the outstanding air combat performance to design goals, and give up the other multi-functional to ensure the "air-to-air" combat capability to achieve the level of F-22.
F-22 on its performance so far can be considered in terms of near-perfect, then a reasonable question is the design of the Chinese aircraft maker will be how to counter the F-22? The answer is not surprising, not at all difficult. Five multi-purpose fighter aircraft are usually, but every fighter in the plan are not the same degree of versatility.
F-22 multi-function of the original program the least, the program revised its versatility is greatly increased. Revised by the U.S. F-22A and began to accept bulk equipment. However, the improved "Raptor" a sharp increase in weight. Early in 1990 from the normal take-off weight of 22.7 tons to 29.6 tons now.
It is easy to understand, a feature of every fighter, take-off weight to be increased in some.
This fact limits the use of more advanced aircraft technology. In short: to aircraft equipment, more features will greatly increase the load when the plane took off, we can see the aircraft take-off weight increased the realization of these features is a prerequisite, not only there is only one type of aircraft such as JSF (Joint Strike Fighter) this need Development of three fighters of different functions is the same type of project.
Chinese designers have mastered the current technology, only in terms of combat capability, you can create a very high standard of fighter, the only question is how the Chinese people in the sky show the strength of military technology, like the Americans to drive F - 22 fighter planes in the Chinese border have begun to show it.
Combat capability and application of technology has determined the weight-level fighter. It can be said that the designers of the development in China, the performance of the fighter program, its goal is not the current F-22A, but in 1995 the "air-to-air" tasks as the main design goals of the YF-22.
Available through the existing 5 on behalf of China's intelligence machine pneumatic appearance of view, this thesis is correct. Based on these data, the main tactical and technical parameters are for the current long-range fighter and close air combat capabilities, which are tactical and technical parameters of the primary consideration is the stealth and mobility.
In any case, the designer of China's very clear the hands of only the existing resources (technical and perhaps funding) to copy the Americans simply will not work. China has always been to find a solution in the development of 5th generation fighter all the way to problems.
China will not publicize the ongoing development of 5-generation machine, the real lack of information (although very large degree of concern) caused some confusion. Chengdu, one of which is that the designers of the Group is well-known in the imitation of the Russian prototype test 1.44. This hypothesis is the one by the U.S. Center for Strategic and International Studies in its report referred to. Subsequently, the hypothesis has been reproduced in several major foreign publications, and then become a matter of course to the "facts."
Author of a reason to object to this widespread view, and is prepared to put forward a view of the logical "facts" is to some extent caused by the Chinese side. But the headache is on the Chinese network of several under construction in Chengdu Group 5 on behalf of the picture plane with a well-known prototype of the test the same as 1.44.
After detailed analysis of the allocation map information, it is clear that the development of the Chinese people in the Five Dynasties and machine plan, both the F-22 will not go this route, it would not go this route 144.
China's next generation of YF-23 fighter and the most unique things are designed to dump the whole dynamic of the V-shaped tail, replacing the vertical tail fin + level of the traditional structures. However, the use of the YF-23 outside the side of a significant tail design, to ensure that the stealth capability, but the efficiency of the corresponding lower tail. In contrast, China's adoption of next-generation fighter extraversion small design, the minimum requirements in stealth, is a comprehensive trade-off the stealth and mobility results.
Full-Motion V-tail design features to improve the stealth aircraft is extremely beneficial. And as a result of a reduction of control surface and the corresponding control, but also help to reduce weight and reduce aircraft drag. However, apart from the control surface load problem, this design is bound to face a test of the flight control system is complicated.
V-shaped tail of the deflection control is very complex, a more complex design of flight control system will certainly increase the level of complexity and development risk. And flight control software is precisely the preparation of the flight control system design is one of the difficulties. Since the wire flight control system applied to the third-generation fighters, most first-class fighters, have been planted in the fall above. YF-23 has not been conservative in favor of the U.S. Air Force, one of the reasons it is so important.
However, the Chinese J-10 aircraft development test set "0 crashed" the development of third generation fighters miracle, have reason to believe that China's aviation science and technology personnel in the flight control software has been used to prepare the level of the ability to respond to this challenge.
If the use of V-shaped tail of the aircraft are used for the thrust vector engines, more than a series of issues may be alleviated, to improve the mobility and agility are also good.
YF-23 but does not use a thrust-vectoring engines, one at the time the United States, the engine thrust vector did not fully mature, the development will further increase the risk, and the other is thinking of its design capacity of over-the pursuit of stealth. YF-23's on the rear-mounted vent groove from the end of the post-B-2 fuselage designed to reduce the aircraft radar reflectivity to the cross-sectional area and improve the ability of infrared stealth. This design is suitable for the bombers, and fighters are not necessarily the. Home-style groove on the end of the engine vents makes no vector nozzle deflection.
The present situation, Russia's thrust-vectoring AL-41 engine has been basically mature, and if the Chinese to adopt the next generation of Russian-made fighter planes of domestic major thrust or thrust vector engines, then the ability to achieve stealth, mobility and the harmonization of agility. Seen from the diagram, the tail of the China Next Generation aircraft have been earmarked for the end of the thrust vectoring nozzle engine room for maneuver.
Based on current information disclosed by Fei Shen developed the next generation of fighter planes in China was closer to four generations of the United States competitive selection of local losers of YF-23, but add a duck wing

(User drawn Shenyang Aircraft Research Institute (601) close to the fourth-generation fighter program F-23, but has been used in the F -10 fighter was the duck-style layout verification, and selection of the main wing stealth effect also did not use the best diamond wings, but rather ordinary, but better mobility trapezoidal swept wing. This will increase mobility in the stealth requirements, and to strike a balance between aerodynamic performance.)
In addition, the wing has also reduced the size of the wing main fuel tank a corresponding reduction in volume. Because, taking into account the issue of stealth, combat aircraft and most of the next generation of plug-ins can not drop tank, all fuel tanks must be loaded by the machine. For the play "world police" the world's intervention in the United States, inter-theater range fighter relatively high requirements; and on the air and the surrounding territory of the Chinese Air Force in terms of operations, there is no need to pursue a range of particularly large. This choice is acceptable.
Compared the two, China's next generation fighter aircraft significantly longer than the length of F-22, which means that even in the largest cross-sectional area equivalent aircraft, China's next generation of fighter planes can be more smooth distribution and the rate of change of cross-sectional area, means a smaller cross, supersonic resistance. It is easy to see that China has chosen the next generation of supersonic fighter planes performance, obviously reflects the high-speed attack the idea of high-speed pursuits.
In the overall appearance of the next generation of fighter planes in China and is very similar to YF-23, the fuselage looks like the beginning of the fuselage and the former two separate nacelle directly embedded into the wing as a whole.
Set up before the main fuselage radar cabin, cockpit, cabin before the landing gear, avionics and missile equipment cabin space. Before the fuselage cross-section of the previous upper and lower approximation of a rounded hexagonal symmetry, and then gradually transition to a circular cross-section, and finally in the middle of the fuselage with the wings fully integrated.
The back part of the inlet and engine compartment, and its still a trapezoidal cross-section, and a very smooth curve after the transition to the wing or fuselage, this program will help reduce the resistance, is also a very good stealth design.
Tail arrangement of the use of wide-spaced to avoid the body of harmful vortex, and take full advantage of the duck-wing vortex useful, so a dramatic improvement in motor state of pitch, roll and yaw control.
More YF-23 advanced F-22 program was defeated, mainly due to the U.S. Air Force of the conservative strategy. And the development by leaps and bounds in the Chinese Air Force and the aviation industry, it is bound to be a comprehensive summary of the F-22, F-23 and 1.44 characteristic of Russia on the basis of their more advanced development of next-generation fighter.
