The J-20 just in service, the next generation fighter began to become users of discussion, and spontaneous to number "J-50 fighters." remember 10 years ago in the J-20 has not yet appeared, there are enthusiastic users named "J-20" results unfortunately. Will it be lucky to continue this time?
We are looking forward to it. As a leading China after 2030 air superiority fighter, users give high expectations will die can be understood. J-31 this number has been used. Then it will be possible to continue later, and the number after J-31 will be lucky.
The success of the next generation of fighters depends on the pace of research and development of advanced engines.
The United States general aviation group develops and demonstrates adaptive cycle fan engines.
The United States Air Force Research Laboratory (AFRL) signed contracts with Pratt & Whitney and GE in 2012 to develop an adaptive engine technology development (AETD) engine with three ducted and adaptive circulating fans.
Because the traditional turbofan turbofan engine technology is thought to have been close to the limit of development bottleneck, think in the future six generation machine first, has appeared to be inadequate. China has so far failed to announce what technology the next generation of engines will use, but has said it is actively developing it. From public data, we can see that a pulse detonation engine technology, Russia and China have been in research and development. But the engine has been considered more suited to space technology than to fighter aircraft.
Unlike Russia, the two largest engine company in the United States still makes major technological changes on the basis of the original turbofan engine, although relatively conservative, but the technology maturity and R & D cycle is much shorter. Neither GE nor Pratt & Whitney will produce a full-size AETD engine, but in this research project, two contractors must refine multiple designs into one. The AFRL limits the size of the engines, and the AETD of the two companies need to be the same size as the F-135 engine, that is to say, to fit into the fuselage of the F-35 fighter.
In the past few decades, China has taken the shape of aircraft first and then into the engine development. Do not know that the cycle of engine research and development is several times the aircraft, because it is often finished aircraft manufacturing, the engine is not beautiful. Since 2000, China has also adjusted its strategy, glued to the world standard and increased the speed of engine research and development. The fourth generation of "WS-15 Emei" has been successful, the 5-generation engine in Ukraine and technical personnel to join the case, will accelerate the process.
