Abstract : The patent concerns a system for improving ride quality of surface effect craft by using air cushion variable volumetric control. The air cushion volume is made resiliently variable by connecting a plenum, having a pressure yieldable member such as diaphragm, bellows or piston, to the air cushion chamber. When the surface effect craft encounters an irregularity which changes the volume of the air cushion, such as rocks or waves, the resilient membrane, bellows, or piston responds to maintain a substantially constant total air volume, thus tending to keep the vehicle at a constant height off the surface and thus reducing accelerations.
