    • The first flight of the unique Kyushu J7W Shinden (magnificent lightning), a canard-configuration single-seat fighter, was made on 3 August 1945, but the end of World War II later in the month brought an end to development and production plans. Designed by a team under the leadership of Captain Masaoki Tsuruno of the Imperial Japanese Navy, the configuration of this aircraft had been effectively confirmed by the flight testing of three specially designed and built MXY6 gliders. The construction of two J7W1 prototypes followed, these each having a slender fuselage also mounting in a mid-position on the nose a short-span foreplane incorporating elevators at the trailing edge. The rear-mounted cantilever monoplane wing was set low on the fuselage, had moderately swept leading edges and conventional ailerons with, just inboard of these on each wing, a fin and rudder extending above also below the trailing edge. The landing gear was of retractable tricycle type; the pilot was accommodated in an enclosed cockpit, directly above the leading edge of the wing, and power was provided by a 1588kW Mitsubishi MK9D radial engine, mounted on the rear fuselage to drive a six-blade pusher propeller. By the end of the war the second prototype had been completed but not flown.

  1. Its like you read my mind! You appear to know so much about this, like you wrote the book in it or something. I think that you could do with a few pics to drive the message home a little bit, but other than that, this is great blog. An excellent read. I’ll definitely be back.|

  2. The “J-” designation referred to land-based fighters of the IJN and the “-W-” to Watanabe Tekkojo, the company that oversaw the initial design; Watanabe changed its name in 1943 to Kyushu Hikoki K.K.

    The idea of a canard-based design originated with Lieutenant Commander Masayoshi Tsuruno, of the technical staff of the IJN in early 1943. Tsuruno believed the design could easily be retrofitted with a turbojet, when suitable engines became available. His ideas were worked out by the First Naval Air Technical Arsenal (Dai-Ichi Kaigun Koku Gijitsusho), which designed three gliders designated Yokosuka MXY6, featuring canards. These were built by Chigasaki Seizo K. K. and one was later fitted with a 22 hp Semi 11 (Ha-90) 4-cylinder air-cooled engine.

    The feasibility of the canard design was proven by both the powered and unpowered versions of the MXY6 by the end of 1943, and the Navy were so impressed by the flight testing, they instructed the Kyushu Aircraft Company to design a canard interceptor around Tsuruno’s concept. Kyushu was chosen because both its design team and production facilities were relatively unburdened, and Tsuruno was chosen to lead a team from Dai-Ichi Kaigun Koku Gijitsusho to aid Kyushu’s design works
