To provide a turbine for generation of propulsion force usable as a generation source for propulsion force in a deep-sea explorer or a vessel and capable of facilitating saving energy.SOLUTION: A turbine for generation of propulsion force comprises: a turbine shaft reduced in diameter as proceeding from one end to the other end: and a plurality of turbine blades formed on a surface of the turbine shaft and extending spirally from one end to the other end of the turbine shaft, and defining a fluid channel between mutually adjacent turbine blades. The fluid channel comprises: a fluid inlet for conducting a fluid at one end of the turbine shaft; and a fluid outlet for ejecting the fluid in an axial direction of the turbine shaft at the other end of the turbine shaft. The fluid channel is reduced in channel area linearly as going along a flowing direction.SELECTED DRAWING: Figure 1

    【課題】海底探査機や船舶等の推進装置の推進力発生源として利用可能で省エネルギー化が可能な推進力発生用タービンを提供する。【解決手段】一方端から他方端に向けて縮径するタービン軸部と、前記タービン軸部の表面に形成され、該タービン軸部の一方端から他方端に向けて螺旋状にのびる複数のタービン羽根とを備えており、互いに隣接するタービン羽根同士の間で流体流路が画成されており、前記流体流路は、前記タービン軸部の一方端において流体を導き入れる流路入口及びタービン軸部の他方端において流体を前記タービン軸部の軸方向に噴出させる流体出口を有しており、前記流体流路は、その流れ方向に沿うに従い、流路面積が線型的に減少することを特徴とする推進力発生用タービン。【選択図】図1
