The ducted propeller with the movable front 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 inflow end; wherein the end, facing the stator, of each paddle is a front edge, and the front edges have the capacity of generating elastic deformation when heated or cooled, so that the front edges face the end of the stator and rotate around the pipe body in the radial direction; the end, facing the blades, of the stator is a rear edge, and the rear edge has the capacity of generating elastic deformation when heated or cooled, so that the end, facing the blades, of the rear edge rotates around the pipe body in the radial direction. The front edges of the blades and the rear edges of the stators can be deformed and deflected at the same time, the inflow angle of the propeller blades and the front stator is zero, an ideal hydrodynamic state is formed, meanwhile, the front edges of the blades and the rear edges of the stators deflect at the same time, and the problem that only the rear edges of the stators are deflected by a large angle is solved.

    本发明提出了一种前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入端之间;其中,桨叶朝向定子的一端为前缘,前缘具有受热或者受冷发生弹性形变的能力,使前缘朝向定子的端部围绕管体径向转动;定子朝向桨叶的一端为后缘,后缘具有受热或者受冷发生弹性形变的能力,使后缘朝向桨叶的端部围绕管体径向转动;设置桨叶的前缘与定子的后缘能够同时进行形变偏转,有助于螺旋桨叶与前定子的入流角为零而形成理想的水动力状态,同时桨叶前缘与定子后缘同时进行偏转,解决了仅有定子后缘进行偏转需要偏转很大角度的问题。
