Propeller blade, unmanned aerial vehicle propeller and unmanned aerial vehicle

The invention discloses a propeller blade, and relates to the technical field of aviation aerodynamic design, the propeller blade comprises a blade main body, the blade main body is a sweepback blade, one end, close to the rotation center of the propeller blade, of the blade main body is a blade root, and the other end of the blade main body is a blade tip; wherein a plurality of airfoils are sequentially arranged on the paddle main body along the direction from the blade root to the blade tip, and torsion angles are formed among the airfoils. The invention further discloses an unmanned aerial vehicle propeller which comprises a plurality of propeller blades, and all the propeller blades are evenly distributed around the rotation center along the circumference. The invention further discloses an unmanned aerial vehicle which comprises the unmanned aerial vehicle propeller. The noise of the propeller can be reduced, and the pulling force and the aerodynamic efficiency of the propeller are improved. 本发明公开了一种螺旋桨
