The invention discloses a marine air propeller blade water-erosion-resistant structure, and relates to the technical field of air propeller blades, a blade body with a groove is adopted, and front edge rubber, a protection sheet and a blade tip covering 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. By means of the structure, the water erosion resistance of the marine air propeller blade can be improved, when a propeller duct water accumulation layer is serious, the marine air propeller blade can bear light paddling capacity, the structural reliability is high, the technology is simple, and the use environment requirement of a marine air propeller is met.

    本发明公开一种船用空气螺旋桨桨叶抗水冲蚀结构,涉及空气螺旋桨桨叶技术领域,采用带凹槽的桨叶本体,在桨叶本体的凹槽内设置前缘橡胶、保护片和桨尖包边,抗水冲蚀结构可以实现船用空气螺旋桨桨叶在船舶低速航行过程中遭遇水花飞溅较大时,或遇到转弯和侧风时,水花卷入非常严重的情形下抵抗浪花冲击和冲蚀的能力,提升桨叶使用寿命。本发明结构可以提升船用空气螺旋桨桨叶的抗水蚀能力,在螺旋桨涵道积水层严重时,可以承受轻度划水能力,结构可靠性高、工艺简单,满足船用空气螺旋桨的使用环境要求。
