Ha-41 Aircraft Engine

The Nakajima Ha-41 was an air-cooled 14-cylinder double-row radial engine with a nominal power rating of 1260 horsepower (939kW). It was a further development of the Ha-5. Variants of this engine were used on early models of the Ki-44 "Tojo" and the Ki-49 "Helen", being replaced in later models by the Ha-109. The Navy designated it the NK5, in anticipation of its use in their own J2N version of "Tojo", but no J2Ns saw operational service. The joint designation was [Ha-34]01.
