摘　　要：随着无人作战飞机纳入作战体系,全天候的作战使用需求对无人机雷电防护提出了更高需求,由于无人机通过地面测控系统进行人机交互,无法向有人机一样具备主动避开复杂气象环境的能力,其雷电总体防护设计显得尤为重要。基于MBSE的系统工程理论,描述了无人作战飞机雷电防护设计总体需求,阐述了无人机雷电防护总体设计流程及主要设计内容,对雷电效应对飞机机体和机载系统的损伤机理进行了分析和研究;综述了飞机系统雷电效应的总体防护设计原则和技术措施,对机体结构和外部设备给出了雷电直接效应防护设计措施,并给出了机载设备雷电间接效应的防护总体设计原则及典型技术方案。With the integration of unmanned combat aircraft into the combat system,the all-weather operational use demands of unmanned aerial vehicles put forward higher requirements for lightning protection.As unmanned aerial vehicles interact with each other through the ground measurement and control system,they cannot actively avoid the complex meteorological environment like manned aerial vehicle.Therefore,the overall lightning protection design of unmanned aerial vehicles is particularly important.Based on the system engineering theory of MBSE,the requirements of the design of the lightning protection for unmanned combat aircraft are described,the overall design process and main design contents of the lightning protection for UAV are described,and the damage mechanism of the lightning effect on the aircraft body and the airborne system is analyzed and studied.The general protection design principles and technical measures for the lightning effect of aircraft system are summarized,the direct protection design measures for the airframe structure and external equipment are given,the protection design principles for the indirect lightning effect of airborne equipment are described,and the typical protection technology schemes are analyzed with examples.
