Traditional submarine propulsion systems consist of a prime mover such as a steam turbine, a gear reduction unit, a shaft, thrust and journal bearings coupled to the propeller. This system severely volume limits the submarine as it requires precise alignment of equipment. It also requires a mechanically complex shaft sealing system. A novel scheme is proposed which utilizes a large hub propeller mounted forward of the control surfaces and powered by a seawater-cooled inverted induction motor mounted around the exterior of the hull. This system also promises to reduce propeller noise and increase low speed maneuverability. Computer analysis of the electric motor design is achieved.
