The specific power of an air cushion vehicle is a function of its dimensional characteristics, i.e., area of the base surface, and, where relevant, width of the peripheral slot. The object of this paper is to minimize this function. This study covers both plenum chamber and peripheral jet ACV, exponential theory being used for the latter. For each type of vehicle two cases are investigated: a single common engine and two separate engines for the lift and propulsion systems. Parts 1 & 2 of this paper, which deals with energy balance and the plenum chamber ACV, are presented. A vehicle propelled by air jet is optimized, specifically for a single fan common to both the lift and propulsion air flows. This optimization also gives the velocity and the volume flow of the propulsion jet together with the characteristics of the cushion (i.e., base surface area and the width of the slot). Finally, the method is illustrated by example calculations which also show the possibilities for analysis.
