The invention discloses a structure and function integrated main shaft design method of a coaxial rotor aircraft, and belongs to the field of aircraft design. Main shaft parts, cables, weak current devices, shock pads and part of a power supply are integrally designed and manufactured. When the cable is practically applied to small and medium-sized coaxial dual-rotor unmanned aerial vehicles and other products having assembling and matching requirements for mechanical structures, structural strength and rigidity and structural parts and power cables, the product design is integrally designed, and cable assembling, strong and weak current separation and signal shielding are completed in the manufacturing stage; part of the circuit board and the main shaft are subjected to function integration, and parts which are time-consuming and tedious in assembly and the main shaft are integrally cured in a manufacturing stage, so that the structural vibration transmission and assembly time is shortened; the rigidity and strength of the main shaft structure can be designed in different areas, the weight of the main shaft is further reduced, the structural compactness of small and medium-sized coaxial dual-rotor unmanned aerial vehicles is improved, and the assembly and maintenance time is greatly shortened.

    一种共轴旋翼飞行器的结构功能一体化主轴设计方法,属于飞行器设计领域。将主轴零件与线缆、弱电器件、减震垫和部分电源进行一体化设计和制造。本发明在实际应用于中小型共轴双旋翼无人机等同时对机械结构、结构强度刚度、以及结构零件与电源线缆有装配配合要求的产品,在产品的设计进行一体设计,在制造阶段完成了线缆的装配和强弱电分离、信号屏蔽,将部分电路板与主轴进行了功能集成,将装配耗时繁琐的零件在制造阶段就与主轴进行整体的固化,减小了结构振动传递和装配时间;可以对主轴结构刚度强度进行分区域设计,进一步减少主轴重量,提高中小型共轴双旋翼无人机结构紧凑性,极大减少装配和维修时间。
