Andrei Chang on "the fourth generation fighter with Chinese characteristics"
Today, Kanwa founder Andrei Chang said that the Factory 132 in Chengdu debut a four generations aircraft in December is real. He said this time the propaganda department of China Aviation Industry Group for this aircraft did not appear to be strictly controlled.
Andrei Chang said that this is a very mature and creative design, Chengdu 132 is a successful plant with a real strength, the winner should not be criticized (Stalin).
Andrei Chang believed the emergence of four generations fighter would bring a complete end to imitation of Chinese military aircraft industrial era. China would become one of the important pole of the world's aviation industry. He also again severely criticized Shenyang Aircraft Corporation cloning Su33 and Su27UBK and believed Shenyang Aircraft Corporation has the need to learn from Chengdu. "The former approach, resulting in a very bad influence on international relations, ruin the already fragile Russian-Chinese military cooperation, and is not necessary." Andrei Chang said.
Chengdu four generations aircraft has all moving vertical tail, section of the all movable acting delta wings, edge design, provide China's fourth generation aircraft with unprecedented maneuvering, especially lateral maneuvering, low maneuvering and to compensate for its inadequate vector propulsion technology. But the delta wing would sacrifice a certain degree of stealth, in spite of this 132 plants is pragmatic, when China stealth materials technology does not reach the level of F22, in order to make some kind of compensation for the high maneuvering, such a design is reasonable. " Andrei Chang said.
Andrei Chang said that it is worth noting that the aircraft is using engine that made in China, there is no installation of vectoring nozzle, this is a recognized proof of WS10 is accepted. It is also a pioneering undertaking in the history of international aviation, as a new aircraft in the flight test phase used a new engine.
Andrei Chang said that the large-scale body design and built-in internal bay are needed, so that J20 is actually a concept of multi-role fighter. After the installation of air refueling, the ability to launch long-range cruise missiles on Guam. At the same time when the next phase installation of large thrust engine, the rear fuselage needs to be properly expanded to accommodate more fans, so this design has some valid.
But Andrei Chang said that for the matter of stealth or the cruising speed, this aircraft does not meet the four generations of US-Russian aircraft and it can not reach the standard of four-generation fighter, it is a typical four generations fighter "with Chinese characteristics". In accordance with J20's empty weight and engine with after burn, the current J20 is incapable to reach supersonic cruise capability. It has no vector propulsion technology. With this alone, this aircraft does not meet the standard of the West and Russian four generations fighter. Furthermore, phased array radar development still requires at least 7-8 years. At the trial flights J20 aircraft is not equipped vector forward nozzle.
However, Andrei Chang said that within 10-15 years after the implementation of WS15 with an 15,000 kg large turbofan engines(the key is material) and active phased array radar, J20 will meet the standard of the Russia and the U.S. to become a fully capable four generations aircraft or even better in maneuvering.
