Title:
HYBRID SHIP PROPULSION SYSTEM HAVING WATERJET PROPULSION MODE AND ELECTRIC PROPULSION MODE BY USING TURBINE POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2021/080318
Kind Code:
A1
Abstract:
The present invention relates to a hybrid ship propulsion system having a waterjet propulsion mode and an electric propulsion mode by using a hybrid multistage power generator. The hybrid ship propulsion system comprises: a pump for supplying water to a rotary turbine portion; a turbine power generation means driven by the rotary turbine portion; a waterjet pipe for generating thrust by discharging to the rear portion of a ship the water that is discharged from the turbine power generation means after power is generated; and a propulsion motor operated by the power generated by the turbine power generation means. According to the present invention, thrust for the ship can be obtained by providing the turbine power generation means in multi-stages and continuously moving a fluid under pressure, and thus, the thrust can be obtained by supplying only the fluid under pressure and electricity can be continuously generated and produced for charging.
