ABSTRACT:
In one general aspect, a shaftless external propulsion system as described herein provides a sleeve configured to be externally mounted over a hull of a marine vehicle. In addition, the shaftless propulsion system provides a rotor and a first stator mounted on the sleeve. The rotor includes a rotor hub that cooperates with a rotor bearing to enable the rotor to rotate about the sleeve, the rotor further comprising rotor blades attached to the rotor hub. The rotor and the first stator are disposed between a collar located at a first end of the sleeve and a collar hub located at an opposite end of the sleeve.
