Abstract:

A variable flow diffuser for use in air cushion vehicles to convert the kinetic energy of the moving air from the main fan into potential energy of air pressure. The conversion is accomplished by passing the air flow from the fan through a flow splitter and diverting it radially outward in all directions along a plane perpendicular to the initial direction of the air flow. The volume of air passing through the diffuser is controlled by placing control vanes around the flow splitter or by moving the flow splitter and a back plate in and out of the air channel. Author
