technology
The Heeres-Type 91 was a single-seater, braced, high - wing metal construction with a Bristol-Jupiter star engine manufactured under license by Nakajima . The landing gear was rigid and the engine was clad with a Townend ring . The aircraft was preceded by a series of prototypes based on the Nakajima NC.
After initial stability and center of gravity problems, delivery began at the end of 1931. A total of 420 aircraft of the basic type were manufactured, 100 of them under license from Ishikawajima .
The type 91-1 had a 540 hp Jupiter engine, the last 21 machines of the type 91-2 delivered were equipped with a Nakajima Kotobuki with 580 hp.
Mission history
The type was only used for a short time and was replaced by the Type 95 ( Kawasaki Ki-10 ) as early as 1935 .
The Ki-10 soon had to give way to the new type 97 monoplane ( Nakajima Ki-27 ). In the Second Sino-Japanese War , Type 91 aircraft were still used on both sides.
