MARINE DUCTED PROPELLER JET PROPULSION SYSTEM Russian patent published in 2018 - IPC B63H11/08

Abstract RU 2666983 C2

FIELD: motors and pumps.

SUBSTANCE: invention relates to embodiments of a marine ducted propeller jet propulsion unit. Marine ducted propeller jet propulsion unit comprises a diffuser/confusor, a steering control nozzle assembly and a radius. Radius is introduced at a transition point between the diffuser/confusor and steering control nozzle assembly. Diffuser/confusor can control a shape of water flow exiting the propulsion unit.

EFFECT: enabling control of acceleration over a large pressure differential generated by a wide range of vessel speeds.
