Abstract

The power requirements of large surface effect vehicles are parametrically examined. The results are first derived in terms of total specific power as a function of the cushion to free stream dynamic pressure ratio and other propulsion and lift system parameters. The propulsion, lift and total power requirements are then examined as a function of vehicle speed, vehicle gross weight and daylight clearance. The fuel fraction-range and payload-range relationship for a given cushion pressure is also examined.
