Ki-64 Rob

The Ki.64 was developed for the Japanese Army Air Force and was one of the most innovative Japanese designs of the war. Original conceived of in 1939, the Ki.64 had a contrarotating propellor coupled to tandem mounted engines and equipped with an evaporative cooling system. The two Ha-40 engines were installed in the fuselage, one in the nose and the second one behind the pilot, with a long axis beneath the pilot's seat, driving contra-rotating propellors in the nose. This arrangment was known as the Ha-201. The Ki.64 also used steam vapour cooling with wing surface radiators to reduce drag even more.

The prototype was damaged on its fifth flight and the programme abandoned.
