The aviation propeller lightning protection system design comprises propeller blades and a propeller hub, and the propeller blades are evenly fixed to the periphery of the propeller hub; the paddle comprises a front edge protection cover, an anti-icing belt, a paddle blade, a paddle root outer sleeve and a lightning protection braid; the front edge protection cover is fixedly adhered to the front edge of the paddle blade; the anti-icing belt is fixedly connected to the guide edge of the paddle blade, and the two ends of the anti-icing belt extend to the front edge protection cover and the blade root position respectively. The paddle root outer sleeve is fixedly positioned at the root part of the paddle blade; the top surfaces of the paddle blades are working surfaces, and the bottom surfaces are non-working surfaces; the lightning protection braid is fixedly laid on the working face of the paddle blade, one end of the lightning protection braid extends to the paddle root outer sleeve, the other end of the lightning protection braid extends to the front edge of the paddle blade, penetrating holes are formed in the corresponding positions of the front edge protection cover and the paddle blade, and the other end of the lightning protection braid penetrates through the penetrating holes to be located on the non-working face side of the paddle blade. The thunder-proof propeller has the advantages that the thunder-proof propeller is simple in structure, good in thunder-proof effect during use and high in safety performance.
