A National Research and Development Program of high bypass ratio turbofan engines has been in process in Japan since 1971. Target performance characteristics of the first-phase 5-ton thrust class engines have been attained, and development of the second-phase engines has been started in 1976. This paper reviews the status of the program, discusses some engineering progress attained, and presents an outline of the second-phase program and engines.
