Abstract:
A propulsion system for propelling a vehicle for movement in relation to a fluid, comprising:a fan mounted for rotation in said vehicle, said fan comprising a solid circular disk, and a plurality of radially spaced blades extending from the surface of said disk, each of said blades having a generally airfoil shape; said fan being mounted such that the axis of rotation of the disk is in the longitudinal vertical plane of the vehicle and defines an angle of between 0 and 50 degrees in relation to the vertical axis of the vehicle, whereby the orientation of said fan defines a sector of the fan which is aftward in relation to the other sectors of the fan; and means for directing the flow of said fluid such that the flow of said fluid across said fan is preferentially through said aftward sector of said fan and in the rearward direction in relation to said vehicle.
