The Kyushu J7W1 "Shinden" ( Japanese震 電) was the most modern design of a Japanese fighter aircraft at the end of the Second World War .
history
Work on this type began in early 1943 under the research designation X-18 at the First Technical Arsenal of Naval Aviation and initially led to an MXY-6 experimental glider , three of which were made and extensively tested, one of which already had a 25 hp engine . Construction work for the actual fighter began in June 1944. The first prototype was ready within ten months, but was not able to take off on its first flight until August 3, 1945 due to problems with the engine cooling system and bottlenecks in the procurement of equipment . During this and the other tests that took place up to the surrender, strong vibrations and instabilities were found at the start. Plans to equip the J7W under the designation J7W2 Shinden Kai with a Ne-130 (900 kp) jet engine were no longer implemented. The second prototype fell into the hands of US troops and was brought to the United States.
construction
Intended as an interceptor against the American B-29 , the design of the "Shinden" contained several unconventional features. The plane was as Canard designed with a short slender hull, a 18 in the rear cylinder - radial engine of Mitsubishi was incorporated, which contains a 6-sheet pusher propeller drive. In the middle of each wing there was a small tail girder that contained the rudder . In the bow, four 30 mm cannons were to serve as armament.
