In the time period from 1970 to early 1975, the Air Force funded development of the YJ101 prototype engine for use in Northrop, YF-17, Lightweight Fighter Prototype. The engine passed a Prototype Preliminary Flight Rating Test PPFRT in early 1974. Flight testing of the YF-17 with YJ101 engines was terminated in early 1975 after a total of 288 aircraft flights for a total of 691 engine flight hours and 2455 total engine test hours. At the completion of the YJ101 Prototype Development Program the USAF funded a one year Continuing Engineering Program. The purpose of this program was to organize and rationalize prototype engine development experience and data into sound technical programming and fiscal information and to investigate and fundamentals of engine development practices. This report summarizes the results of the earlier Prototype Development effort and the flight test program and discusses the results and conclusions of the Continuing Engineering Program.
