INVESTIGATION OF CONTROLLED FLOW PHENOMENA FOR AIR CUSHION VEHICLES

Abstract

Findings are presented of an investigation of controlled flow phenomena for air cushion vehicles. Objectives were: achieving efficient, practical approximations to ideal controlled flow, evaluating the merits of controlled flow configurations in the hovering flight regime by comparing their performance and stability with conventional plenum and peripheral jet designs, and determining the characteristics of integrated stabilization, propulsion, and control systems in a controlled flow configuration. The theoretical expressions of ideal hovering performance for single and concentric peripheral jet configurations are derived and presented. Hovering performance results are presented for the several versions of the circular, square, single fan oval and tandem fan oval models, in that order, and concludes with two versions of the external flow model.
