摘　　要：大气中子是航空高度下造成航空器机载电子系统翻转故障的主要辐射源。面对航空单粒子效应与航空高度影响关系,该文提出一种基于协同进化的单粒子翻转故障生成方法。生成的故障数据用于模拟实际中子通量随高度变化的规律,为机载电子设备单粒子效应加固和防护实验提供数据支持,同时也可以用于分析航空机组人员飞行期间所接收的中子辐射剂量。验证结果表明,该单粒子翻转故障生成方法生成故障数据与真实高度变化下单粒子失效特征吻合,能够满足器件航空单粒子效应加固测试的需求。Atmospheric neutrons are the main radiation sources that cause the turning fault of the aircraft′s onboard elec-tronic system at avionics altitude.Aiming at the influence relationship between the aviation single event effect and aviation alti-tude,a single event turning fault generation method based on co-evolution is proposed in this paper.The generated fault data is used to simulate the variation rule of actual neutron flux with altitude,provide data support for single event effect reinforcement and protection experiments of the onboard electronic device,and analyze the neutron radiation dose received by the airline crew during flight.The verification results show that the fault generation data of the single event turning fault generation method is consistent with the single event failure characteristics under variation of real altitudes,which can meet the aviation single event effect reinforcement test requirement of the device.
