Planning of air cushion transport vehicles
Abstract
The design of an air cushion vehicle in which bypass engines are used to provide the air for the air cushion and the reaction force to move the vehicle was studied. When the engines are first started, all of the air from the outer path is used to create the air cushion. As the vehicle accelerates, less of the air from this path is used to support the cushion, and finally at full speed all of the air is used to move the vehicle, with aerodynamic forces maintaining the cushion. It is concluded that there is an optimal ratio of air flow through the two paths in the engine. The optimal length of the acceleration run increases with increasing mass of the vehicle.
