摘要: 无人机(UAV)的任务工况与环境场景对飞行安全影响极大,为研究不同飞行环境对UAV地面撞击风险的影响,需要分析不同运行工况下的UAV地面撞击事故的边界条件。首先分析影响UAV运行安全的飞行环境因素,考虑不同任务场景的地面人口密度和遮蔽物保护能力,并引入环境影响因子,用以分析不同环境场景的气象、地理和通信等要素;然后以每飞行小时地面撞击事故伤亡人数为评价指标,建立UAV地面撞击事故评估模型;最后计算不同UAV在多种任务场景和环境场景工况下的风险参数,并加以对比。结果表明:飞行环境中的气象、地形和通信等因素对UAV地面撞击风险影响较大,随着环境场景的恶化,UAV运行每飞行小时伤亡人数量级也有较大变化,增加幅度从10-8上升至10-5

Abstract: In order to study impacts of different flight environments on UAV ground impact risks, it is necessary to analyze boundary conditions of UAV ground impact accidents under different flight operation conditions considering mission conditions and environment scenarios of UAV have a great impact on flight safety. Firstly, flight environment factors affecting UAV safety were analyzed, in which ground population density and shelter protection capability of various mission scenarios were considered and environment influencing factors were introduced to analyze meteorological, geographical and communication elements. Then, an evaluation model of UAV ground impact accidents was established with number of casualties per flight hour as evaluating indicators. Finally, risk parameters of various UAVs in different mission and environmental scenarios were calculated and compared. The results show that meteorological, terrain and communication factors of flight environment have a great impact on UAV ground impact risk. With the deterioration of environment, number of casualties per flight hour of UAV operation would change significantly with an increase rate from 10-8 to 10-5.
