Abstract : The patent describes an air cushion landing system (ACLS) for an aircraft including a pair of wind pod-mounted inflatable trunks, and an air supply and exhaust system for inflating and deflating the air cushion trunks. For inflating, a swiveled fan driven from a high pressure turbine engine compressor bleed source directs incoming air from a sealable intake port to the respective trunk. For deflating, an actuator connected to a linkage network swivels the fan, plugs the intake port and opens an exhaust door positively drawing air out of the trunk and exhausting it to the atmosphere.
