Abstract
A rapidly reversible air propeller shroud system is provided for operating an air cushion vehicle more efficiently both in forward and reverse direction travel and maneuvering modes. The shroud includes a sectionally rigid portion of aerodynamically efficient form for operating the vehicle in one direction of travel; and in combination therewith an otherwise inoperative inflatable collar which may be rapidly inflated to expand so as to modify the aerodynamic characteristics of the shroud for operation of the propeller efficiently in reverse direction thrust mode.
