The invention relates to a novel spiral claw in the field of propellers. The spiral claw is more efficient than a propeller. Axial and radial air is sucked through claw teeth on the spiral claw; air is led into the bottom of the spiral claw under the action of the drainage groove; and the air is discharged downwards under the action of the raised surrounding edge. Therefore, axial counter-acting force is generated. The area with the maximum rotation center line speed is fully utilized, and axial air and radial air can be utilized at the same time; and under the condition of the same diameter and rotating speed, larger acting force is generated compared with a propeller.

    本发明涉及是一种螺旋桨领域里一种新型的螺旋爪。是一种比螺旋桨更高效的螺旋爪。通过螺旋爪上的爪齿吸入轴向和径向的空气;在引流槽的作下使空气引入螺旋爪底部;再在凸起的围边作用下使空气向下排出。从而产生轴向反作用力。充分利用旋转中线速度最大区域,还能同时利用轴向和径向空气;在相同的直径、转速的情况下比螺旋桨产生更大的作用力。
