The invention discloses a propeller blade lightning protection structure and a forming method thereof.The propeller blade lightning protection structure comprises a propeller blade and a blade handle, one end of the propeller blade is connected with the blade handle, the two sides of a guide edge of the other end of the propeller blade are coated with nickel covered edges, and the two sides, opposite to the nickel covered edges, of the other end of the propeller blade are coated with lightning protection copper nets; an ionization channel is arranged between the lightning protection copper net and the nickel covered edge, and the nickel covered edge is connected to the blade handle through a lightning diversion belt. The nickel covered edges and the lightning protection copper nets which are arranged at intervals wrap the propeller blades, so that the coverage range of the lightning protection range of the propeller blades is larger, the strength is more reliable, later painting is facilitated, and the process effect is good; meanwhile, the nickel alloy covered edge and diversion belt lap joint design is combined, and one end of the lightning diversion belt is inserted into the groove of the blade handle, so that the length and the weight of the lightning diversion belt are reduced.

    本发明公开了一种螺旋桨桨叶防雷结构及其成型方法,防雷结构包括桨叶片和叶柄,桨叶片的一端与叶柄连接,桨叶片另一端的导边两侧包覆有镍包边,该桨叶片另一端与镍包边相对的两侧包覆有防雷铜网,防雷铜网和镍包边之间设置有电离通道,镍包边通过一雷电导流带连接至叶柄。本发明通过在桨叶片上包覆间隔设置的镍包边和防雷铜网,从而螺旋桨桨叶的雷电防护范围覆盖范围更大,强度更可靠,也便于后期刷漆,工艺效果好;同时,结合镍合金包边和导流带搭接设计,以及雷电导流带的一端插入叶柄的凹槽,减少了雷电导流带的长度和重量。
