摘要

摘要: 针对无人机系统安全性需求,首先根据载人航空器适航审定规范及安全性评估依据,表明由于无人机系统的特殊性造成直接应用现有安全性评估流程和评估方法具有局限性.在此基础上提出无人机系统适航安全性评估的几点改进:①考虑无人机系统包括无人机和综合保障设备,扩大安全性评估边界进行无人机系统级的功能危险分析;②考虑无人机系统“人机分离”特点,需要对无人机系统失效状态的严重程度进行重新分级和定义;③考虑无人机系统本身受起飞质量的影响很大,强调必须根据无人机系统分类对地面撞击和空中碰撞两个关键事件进行安全性分析.结果表明:上述改进从无人机系统本身特点出发,通过给定的目标安全水平进一步确保安全性.

Abstract: Aiming at safety requirement for unmanned aircraft system(UAS),it was initially demonstrated that current safety assessment process and methodology based on regulation and reference for manned aircraft were limited for UAS because of its unique features.In views of this principle,some improvements for UAS safety assessment were proposed:(1) take consideration of UAS including the unmanned aerial vehicle and assured equipments,and enlarge the scope of safety assessment during functional hazard analysis at system level;(2) take consideration of the feature that pilot and unmanned aircraft are physically separated,and reclassify and redefine the serious level of UAS failures.(3) consider that the quality of take-off has a huge impact on system,and the safety analysis must be conducted for two key events-‘air collision’ and ‘ground impact’.The result indicates that the above improvements are in accordance with features of UAV and ensures safety through establishing targeted safety level.
