Stop flying after 32 test flights？ ! The verification machine with high hopes in Japan is called ＂toy＂

　　　　　　 CCTV News:Japan’s "Shenxin" verification machine, which had high hopes, ended its last flight test a few days ago. However, what makes the outside world feel suspicious is that "Shenxin" only announced its stop after a total of 32 flight tests. Is this a normal retirement after the test, or is it a problem?

"Mind" verification machine

　　　　　　 On October 31st, the X-2 "Shenxin" technical verification machine with high hopes from Japan completed its last test flight. "Heart" is a technical verification machine developed by the Japanese Defense Equipment Agency entrusted by Mitsubishi Heavy Industries Minghang Komunan Factory, which paves the way for Japan’s self-developed fifth-generation fighter.

　　　　　　 Since its first flight on April 22, 2016, from Nagoya Komaki Base to Gifu Base of Japan Air Self-Defense Force, "Heart" has carried out a total of 32 flights including various experiments and tests. According to the plan, Japan will finally decide in 2018 whether Japan’s next-generation fighter will be independently developed or jointly developed after analyzing a large amount of data accumulated during the "Heart" test.

　　　　　　 It was grounded after 32 test flights, which made the outside world somewhat confused. Some people think that "Mind", as a technical verification machine, is originally intended to carry out verification flight tests of various technologies. After verification, it will of course be grounded and the next stage of work will be carried out. There is also a view that even in the field of technical verification machines, the number of test flights of "Shenxin" is too small. The X-31 technical verification machine in the United States flew more than 500 times before it was retired, while Japan, whose aviation foundation is far inferior to the United States, only spent 32 times to "get it done", which is not in line with common sense. Some netizens even believe that the termination of the test flight means that the project is dismounted.

"Mind" verification machine

　　　　　　 After World War II, the equipment of Japan’s Self-Defense Forces was mostly produced with the assistance and support of the United States. In recent years, the weapons and equipment exported by the United States to Japan accounted for more than 90% of Japan’s overseas imports. But in fact, Japan’s efforts to build "Japanese fighters" have never stopped.

　　　　　　 Since 2006, after the F-1 fighter plane developed by Japan after World War II was retired, the Japanese Self-Defense Force has no purely domestic fighters. At present, the technologies of several major fighter aircraft models F-4, F-2 and F-15J in active service are all from the United States, and some even directly imported from the United States.

"Mind" verification machine

　　　　　　 According to Japan’s "Economic News" report, in order to develop "Mind", Japan has invested about 40 billion yen or 2.3 billion yuan to promote development since 2009. If the research and development time of key technologies and engines in the early stage is counted, it will take a total of 20 years, and the determination can be seen. However, Japan was interrupted by the United States when it was preparing to build a complete aviation industry chain in the 1980s, so in the end, Japan did not form a complete aviation industry system, and there were obvious shortcomings in the overall design of aircraft, aero-engines, stealth technology, etc. In addition, the United States had a tight blockade on stealth technology, and had previously refused to "mind" to conduct electromagnetic tests in the United States, so it was difficult for Japan to develop a new generation of domestic fighters by its own strength in a short time.

　　　　　　 The research and development of the fifth-generation aircraft not only requires huge funds, but also has a very high technical threshold. However, as allies, the United States and Japan have great differences on whether Japan should independently develop fighter jets. The American Defense News once commented that Japan’s top priority should be to ask the United States to improve its F-15J aircraft and actively purchase the fifth-generation fighter F-35. Some American experts even called "Mind" the "redundant toy" of Japan Air Self-Defense Force, which shows the pressure on its research and development of "Mind".
