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. La présente invention concerne un système de propulsion de navire hybride ayant un mode de propulsion par jet d'eau et un mode de propulsion électrique à l'aide d'un générateur d'énergie hybride à étages multiples. Le système de propulsion de navire hybride comprend : une pompe pour fournir de l'eau à une partie de turbine rotative ; un moyen de génération d'énergie de turbine entraîné par la partie de turbine rotative ; un tuyau de jet d'eau pour générer une poussée par décharge vers la partie arrière d'un navire, l'eau étant évacuée du moyen de génération d'énergie de turbine après la génération d'énergie ; et un moteur de propulsion actionné par l'énergie générée par le moyen de génération d'énergie de turbine. Selon la présente invention, une poussée pour le navire peut être obtenue en fournissant le moyen de génération d'énergie de turbine à étages multiples et en déplaçant en continu un fluide sous pression, et ainsi, la poussée peut être obtenue en fournissant uniquement le fluide sous pression et l'électricité peut être générée en continu et produite pour la charge. 본 발명은 하이브리드 다단 발전장치를 이용한 워터제트 추진방식 및 전기 추진방식을 갖는 하이브리드 선박 추진시스템에 관한 것으로서, 회전 터빈부에 물을 공급하는 펌프와; 상기 회전 터빈부에 의해 구동되는 터빈 발전수단과; 상기 터빈 발전수단에서 발전한 후 배출되는 물을 선박의 후방으로 배출시켜 추진력을 얻는 워터제트 파이프와; 상기 터빈 발전수단에서 발전된 전력에 의해 작동되는 추진모터를 포함하는 것을 특징으로 한다. 본 발명에 의하면, 터빈 발전수단을 다단으로 구비하여 압력을 가진 유체를 연속 이동시키면서 선박의 추진력을 얻음으로써, 압력을 가진 유체의 공급만으로도 선박의 추진력을 얻을 수 있고, 전기를 연속적으로 발전 생산시켜 충전할 수 있는 효과가 있다.
