CA 2316094
There is provided a combined pressure and thrust fan consisting of a solid circular disk with a plurality of radially spaced airfoil-shaped blades. The selective direction of airflow over an aft sector of the fan provides net thrust. The fan may be mounted in an air cushion vehicle with appropriate ducting or vanes to cause the major portion of the airflow to move radially through the aft sector. The fan according to the invention may also be used as an immersed propulsion system.
