AN EXPERIMENTAL INVESTIGATION OF INTERNAL FLOW EFFECTIVENESS FOR SEVERAL AIR CUSHION VEHICLE ARRANGEMENTS.

Abstract

An experimental investigation was conducted to determine the effect of planform and fan arrangement on internal distribution efficiency and uniformity of peripheral flow, with application to '5-Ton Payload,' logistic-type air cushion vehicles. The results indicate that overall vehicle effectiveness is highly dependent on the lift distribution system arrangement with maximum efficiencies ranging from 52 to 77 percent. For each configuration, an optimum distribution plenum height is suggested that has a notable similarity to the optimum divergence angle found in conical diffusers. (Author)
