The invention discloses a 4D printing deformable propeller, and belongs to the technical field of propeller blade structure design. The propeller comprises a propeller hub and the deformable blades, the multiple deformable blades are evenly arranged in the circumferential direction and fixedly installed on the propeller hub, the whole deformable blades are integrally formed through 4D printing, heating parts are arranged in the deformable blades, and after the temperature of the heating parts rises, blade materials deform; and finally, the angle of the deformable blade is changed. The low-noise and high-thrust requirements of the propeller can be met, and the adjusting mode is flexible.

    本发明公开了一种4D打印可变形螺旋桨,属于螺旋桨桨叶结构设计技术领域。螺旋桨包括桨毂和可变形叶片,多个可变形叶片沿圆周方向均匀布置且固定安装在桨毂上,可变形叶片整体通过4D打印整体成型,可变形叶片内部具有加热部件,加热部件温度升高后使得叶片材料发生形变,最终使得可变形叶片的角度发生变化。本发明能够满足螺旋桨的低噪声和大推力要求,并且调节方式灵活。
