Abstract
In an aircraft air cushion takeoff and landing system with a flexible trunk section in the form of a large expandable tube, having multiple air exhaust holes in the bottom thereof, encircling the bottom of the fuselage, a group of flexible finger-like protrusions beneath the forward section of the trunk. The downwardly extending finger-like protrusions make intermittent contact with the ground surface to suppress vertical vibrations in the trunk when the aircraft is hovering at ground level with the trunk inflated.
