1970, China launched a variety of "new fighters," and only designed, technically sound, "Flying Leopard" ultimate fruition. (Data plan)
Phoenix Military Defense Commentary April 7
April 6, The Military Channel on phoenix "lost models" to investigate, over 40% of users agree with this view: -6 straight year, straight -7, F -9, -13 F, there is strong -6fatal flaw is the main reason for dismount.
But there are a considerable number of users, still bear a grudge against these aircraft dismount. In their view, if not the "economic construction", China continues to invest a lot of money developing these new fighters, and now the Chinese Air Force will be more powerful.
Need to point out that, during the Cultural Revolution launched a large number of military aircraft, most of the existence of such kind of problems, many more than China's own technological capabilities, there are many in the development of the beginning took a detour to produce a variety of congenital and acquired defects.Failure developed in four fighters F -9, F -12, F -13, strong -6, for example, dismount is not just lack of money, but the design error, or can not resolve the technical obstacles.
J -12: out of date when it started to develop
J -12 is the failure of the Cultural Revolution, the four military aircraft, the closest to the success of a model prototype has been developing multi-start test, performance reached the design target. But in fact, when the development of this aircraft had been identified at the beginning of defeat.
J -12 fully reflects the situation at the time of China's aviation industry: the lack of adequate technology accumulation, it is difficult to introduce foreign advanced technology and fully tap the potential of existing technologies. F -12 fighter accurately to the right direction, that is subsonic low altitude maneuverability. China was also the J -12 with existing technology, design and produce the best aircraft. But the body is too small and the nose inlet, so that J -12 lost to development potential. After the 1980s the face of the battlefield, no radar, can only carry two missiles in the J -12, seems anachronistic.

J -9: Error caught in high-altitude high-speed
Air Force F -9 is the product of blind pursuit of high-altitude high-speed, but also in the process of development and deepening of this error, the speed index increased from 2.3 Mach 2.6 Mach, the maximum ceiling from 20,000 meters to 26,000 meters, and combat radius was only 350-450 km. Can be seen from the indicators, J -9 is just another "airport defenders." In the age of three generations of machines has been around, which only have the high-altitude high-speed capability, but lack of mobility and endurance of the fighter, it is difficult to meet real needs.
J -9 if can continue to develop, the earliest expected to be in service around 1990.MiG aircraft performance far less than -25, which is not only faster, but at least up to a combat radius of 1,100 km. The combat has also been proven that three generations of MiG -25 and not against the machine. The performance of a chip even Johnson J -9, once the face of the Gulf War will come out this level of combat, will be an embarrassment.
J -13: Advanced contradictions between indicators and outdated engine
F -13 fighter in the four developed indicators to set a relatively reasonable, but also to accurately grasp the pulse of the development of three generations of machines. But the F -13 suffered a serious bottleneck in their level of technology.
J -13 -6 originally planned turbofan engines equipped, but the Chinese MiG -23 introduced the P-29 engine and found the latter far less than the former performance.J -13 then change the use of P-29, ie -15 turbojet engine. But compared to the three generations of machines, MiG -23 of the turbojet engine also appears to lag behind, even to catch up in the thrust-weight ratio F-16, but the mobility aspects of subsonic combat range and will also be limited, so only J -13 achieve "second generation semi-" level. More critical is the generic turbojet engine development -15 also need a long time before this date in 1990, the engine is almost impossible to imitate the success of this cost-effectiveness will be intolerable.
Strong -6: variable wing technology developed the ultimate proof not necessary
J -13 -6 and strong late-type design is very close to, but stronger -6 bold use of variable-geometry wing design, is the main reason for failure. Although the swept wing can increase landing capacity and operational flexibility, but also brings a substantial increase in body weight, and severely limits the number of wing pylons, behind this extremely detrimental to the fighter-bombers.
Strong in design concepts similar to -6 MiG -27, MiG -27 but the biggest drawback is the lack of payload. The former Soviet Union in the variable-geometry wing design, there is no realization of the West "Tomcat", "wind" owned by automatically and quickly adjust the variable wing and do not have variable wing pylons technology, mobility and firepower reduced. China can only refer to the Soviet Union variable wing design, technology accumulation is basically zero, but could not break above technical difficulties. And history shows, "Tomcat", "wind" is the last variable-wing fighters, the West has finally given up this technology. Strong -6 ultimately not selected Chinese fighter-bombers, but the choice of technology is more reliable, more payload and range fighter-bombers JH -7, which was born Chinese main sea and air combat aircraft "flying leopard."
In summary, the 1980s, the pace of China's fighter development "slow down" is necessary. Again looked down, understand the J and J -8 -7, while the accumulation of technology, in the 1980s to redefine the JH and J -10 -7 design, finally realized the great development of three generations of Chinese machines.
