Needed Research and Development on V/STOL Powerplants for Navy Aircraft 640344

This paper presents an estimate of powerplant needs for future Navy V/STOL aircraft. Helicopters, propeller powered, and jet powered type V/STOL aircraft are each discussed from the viewpoint of the needed research and developments required to provide improved aircraft performance. Specific engine needs as well as component research needs are examined and particular emphasis is placed on reduction in transmission system weight for helicopters. Lightweight, variable camber propellers and lightweight transmission systems are needed for propeller powered V/STOL aircraft. Three new turbofan engines are foreseen as being needed for future jet V/STOL attack type aircraft.
