To provide a rotary propulsion device or a rotary power generator capable of adjusting difference in deformation behaviour according to a position receiving force of a propeller by imparting anisotropy to a core member which is a central part.SOLUTION: A rotary propulsion device or a rotary power generator includes a hub H and a plurality of blades B fixed to the hub H and extending in a radial direction from the hub H. Each blade B is composed of a core member 21 composing a central part, and an outer surface member 22 formed to cover the periphery of the core member 21, and the core member 21 has anisotropy with different elasticity modulus for each direction.SELECTED DRAWING: Figure 1

    【課題】中心部であるコア部材に異方性を持たせることにより、プロペラの力を受ける個所による変形挙動の差を調整することができる回転式推進装置または回転式発電装置を提供する。【解決手段】ハブHと、ハブHに対して固定されると共に、ハブHからラジアル方向に延びる複数のブレードBと、を備えた回転式推進装置または回転式発電装置であって、各ブレードBは、中心部を構成するコア部材21と、コア部材21の周囲を覆うように形成される外表部材22と、で構成されており、コア部材21は、方向ごとに弾性率が異なる異方性を有するものである。【選択図】図1
