COMBINED PROPULSION SYSTEM VESSEL Russian patent published in 2017 - IPC B63H1/00 B63H1/16 B63H5/14 

FIELD: transportation.

SUBSTANCE: combined propulsion system comprises a body vessel in the form of an axially symmetric ring of the ship heads to accommodate a reversible electric motor performance and immersion features, placed downstream of the impeller coaxially with it, the propeller. Reversive electric motor has a built-in stator, and a rotor, slidably disposed in the housing. The impeller without hubs includes blades, that are attached to the inner side of the circular ring. The circular ring is suspended on thrust structures and fixed inside the rotor of mentioned electric motor. The propeller is located at the end of the propeller shaft, which passes along with deadwood. The propeller and impeller are equipped with actuators, that are capable of providing them with an opposite rotation and equipped with autonomous stoppers, which are arranged to provide a stop of rotation independently.

EFFECT: increase of the propulsion ship complex efficiency for all modes of operation of the vessel.
