The Air Cushion Landing System (ACLS) is based on the ground effect principle in which a stratum of air, instead of wheels, is used as the aircraft ground contacting medium. The ACLS employs a large expandable tube which encircles the bottom of the fuselage providing both an air duct and seal for the air cushion. The bottom of the tube (trunk) contains more than 6700 nozzle holes through which low pressure air passes into the air cushion cavity. The air source for the system is an onboard auxiliary turbine driven fan supplying a low pressure (about 1 psig) within the cushion cavity which produces a force equal to the vehicle's weight.
