Water-erosion-resistant structure of marine air propeller blade

The utility model discloses a water erosion resistant structure of a marine air propeller blade, which relates to the technical field of air propeller blades and adopts a blade body with a groove, and leading edge rubber, a protective sheet and a blade tip covered edge are arranged in the groove of the blade body. The water-erosion-resistant structure can achieve the capability of resisting wave impact and erosion when the marine air propeller blade encounters large water spray splashing in the low-speed sailing process of a ship or encounters turning and crosswind, and under the condition that water spray involving is very serious, and the service life of the blade is prolonged. According to the structure, the water erosion resistance of the blade of the marine air propeller can be improved, when a water accumulation layer of a propeller duct is serious, the blade can bear light paddling capacity, the structural reliability is high, the process is simple, and the use environment requirement of the marine air
