The invention belongs to the technical field of body lightning protection, and particularly relates to a design method of a lightning protection net of a helicopter body structure with a main path. A complete thunder and lightning protection net is arranged for a helicopter body structure, the thunder and lightning protection net enables skins which are prone to being attached and swept by thunder and lightning to form a good electric conductor with the resistance value meeting the requirement, and the expression form of the composite skins is skin metallization, that is, copper nets with appropriate current-carrying capacity are laid according to thunder and lightning partitions, and therefore the lightning protection effect is achieved. Circuit conduction can be realized among different skins; a proper lightning protection main path is arranged between an inlet and an outlet, which are easily attached by lightning, of the slave machine body structure; the invention provides a design method of a lightning protection net of a helicopter body structure with a main path, and provides an electric lap joint processing method between different configuration structures under different conditions, a laying principle of a copper net and a laying principle of a flow guide strip in detail at the same time; and great reference significance is provided for thunder and lightning protection design of a helicopter body structure.

    本发明属于机体雷电防护技术领域,具体涉及具有主通路的直升机机体结构雷电防护网设计方法;为直升机机体结构布置一张完整的雷电防护网,该雷电防护网能使各易受雷电附着和扫掠的蒙皮组成一个阻值符合要求的电的良导体,对复合材料蒙皮而言其表现形式为蒙皮金属化,即根据雷电分区铺设载流能力合适的铜网,且不同蒙皮之间可以实现电路导通;从机体结构易受雷电附着的进口和出口之间应布置一条合适的雷电防护主通路;本发明在提出一种具有主通路的直升机机体结构雷电防护网设计方法的同时,详细给出了不同情况下不同构型结构之间的电搭接处理方法、铜网的铺设原则以及导流条的铺设原则;为直升机机体结构雷电防护设计提供了极大的参考意义。
