Development of the XF3-30 Turbofan Engine

The XF3-30 is the low-bypass-ratio turbofan engine which has been developed to power the XT-4 intermediate trainer for the Japan Air Self Defence Force. This engine has been designed and tested in accordance with the requirements of MIL-E-5007D with some modifications to meet the particular requirements of an intermediate trainer and circumstances in Japan. All of the qualification tests including endurance tests, low cycle fatigue test, altitude test, foreign object ingestion test and environmental icing test were successfully completed by Mar. 1986 and flight test of the XT-4 trainer aircraft powered by two of the XF3-30 engines has proceeded without any-engine related problems.Copyright © 1987 by ASME
