摘要

Safran has begun studies into the use of hybrid power on helicopters as a way to cut fuel consumption. The French company believes that the right-sizing of engines through the use of a turbine-electric hybrid power system could cut fuel consumption by 10-15%. "The main issue in twin-turbine helicopters is that the engine is sized for one-engine inoperative [OEI] flight," says Cyrille Poetsch, executive vice president for programs at Safran Helicopter Engines (formerly Turbomeca). Engine failures on modern helicopters are infrequent, with the result that engines are not fully optimized for the size of the aircraft.
