Summary
The Japanese Air Technical Arsenal developed the TSU-11 for the Yokosuka MXY7 Navy Suicide Attacker Ohka Model 22 (Allied Code Name Baka). A Campini-type (partial jet) engine, the TSU-11 was as an interim development between the rocket-powered Ohka Model 11 and the Ne 20 turbojet-powered Ohka Model 43. The objective was to increase the Ohka's range so that it could be released by its delivery aircraft at a greater range from the intended target.
The TSU-11 consisted of a Hitachi Hatsukaze Ha 11 Model 11 four-cylinder, inverted in-line, air-cooled engine driving a single-stage axial-flow compressor. Four fuel burners located aft of the compressor provided afterburning. Three engines were built, and one flight was made in July 1945, when an Ohka 22 was launched from a Yokosuka P1Y Ginga (Allied Code Name Frances). But the war ended before the Ohka 22 became operational.
The engine is installed in the museum's Ohka Model 22 aircraft.
