ABSTRACT:
The inflatable cell portion(s) of an air cushion type undercarriage for airplanes, air cushion vehicles, or the like, of the type which are formed with air outlet openings in the ground tangent areas thereof are individually provided with air flow control devices having highly abrasive tear-resistant bottom surfaces disposed externally of the cell fabric, in lieu of the conventionally employed coverply or "wear strips". The devices of the present invention receive the ground contact abrasion and tear-inducing stresses normally imposed upon the cell fabric, and protect the latter in improved manner; and are simply snap-fitted (and thereby detachably locked) into the cell fabric apertures, and may be easily replaced as required.
