The Hitachi Hatsukaze was a series of aircraft engines built in Japan prior to and during World War II. They were air-cooled, four-cylinder, inverted inline engines developing around 82kW (110hp). The original Hatsukaze was a license-built Hirth HM 504.
Hatsukaze engines were produced in very large numbers, since this motor was the powerplant for the licence-built Bcker B 131 Jungmann variants that were the standard primary trainers for the Imperial Japanese Navy and Imperial Japanese Army. The naval version of the engine was designated GK4, the army version Ha-47, and the joint-army-navy designation was Ha.
The Hatsukaze was also linked to a compressor to create a primitive jet engine called a motorjet, the Tsu-11 intended to power Ohka flying bombs.
