The ducted propeller with the movable rear stator comprises a pipe body, and the two ends of the pipe body are the inflow end and the outflow end respectively. The paddle body is arranged in the pipe body and is provided with paddles; the stator is arranged on the inner wall of the pipe body and is positioned between the paddle body and the outflow end; wherein the end, facing the stator, of each paddle is a rear edge, and the rear edges have the capacity of generating elastic deformation when heated or cooled, so that the end, facing the stator, of each rear edge rotates around the pipe body in the radial direction; one end, facing the paddle, of the stator is a front edge, and the front edge has the capacity of generating elastic deformation when heated or cooled, so that the front edge rotates around the pipe body in the radial direction towards the end part of the paddle; the rear edge of the blade and the front edge of the stator can be deformed and deflected at the same time, the inflow angle of the propeller blade and the rear stator is zero, an ideal hydrodynamic state is formed, meanwhile, the rear edge of the blade and the front edge of the stator deflect at the same time, and the problem that only the front edge of the stator needs to deflect by a large angle is solved.

    本发明提出了一种后定子可动的导管螺旋桨,包括管体,两端分别为流入端及流出端;桨体,设置在管体内并具有桨叶;定子,设置在管体内壁上并位于桨体与流出端之间;其中,桨叶朝向定子的一端为后缘,后缘具有受热或者受冷发生弹性形变的能力,使后缘朝向定子的端部围绕管体径向转动;定子朝向桨叶的一端为前缘,前缘具有受热或者受冷发生弹性形变的能力,使前缘朝向桨叶的端部围绕管体径向转动;设置桨叶的后缘与定子的前缘能够同时进行形变偏转,有助于螺旋桨叶与后定子的入流角为零而形成理想的水动力状态,同时桨叶后缘与定子前缘同时进行偏转,解决了仅有定子前缘进行偏转需要偏转很大角度的问题。
