Recently, the growing amount of unmanned aerial vehicles (UAVs) has brought a huge threat to the safety management of manned aircraft operation, in which the UAV airborne collision is an incident that would lead to serious damage to the manned aircraft and will affect its operational safety significantly. In the present paper, the bird strike data over the year of 1990∼2019 is analyzed, which demonstrates that the engine is the most vulnerable component under bird strike, and the most severe hazard would happen during the flight phases of take-off, climb and approach. The dynamic response of UAV airborne collision with the manned aircraft engine is simulated based on the combination of FEM (Finite Element Method) and CFD (Computational Fluid Dynamics) simulations. Not only the damage of fan blades but also the thrust loss of the engine core caused by the damage in the compressor core is taken into account. The damage severity level of the engine under UAV airborne collision is studied by considering different collision configurations, different collision positions and different flight phases. Both the damage of fan blades and the percentage of thrust loss are considered to reflect the influence of UAV airborne collision on the aircraft operation. It is expected that this study can be used to guide the airborne safety assessment of UAV airborne collision.

近来，无人驾驶飞机（UAV）数量的增加对有人驾驶飞机的安全管理构成了巨大的威胁，在这种情况下，无人机的空降事故将导致对有人驾驶飞机的严重损害，并影响其运行。安全性显着。本文对1990〜2019年的鸟击数据进行了分析，结果表明发动机是鸟击下最易受伤害的部件，在起飞，爬升的飞行阶段会发生最严重的危险。和方法。基于有限元方法和CFD（计算流体动力学）模拟的结合，模拟了无人机与有人驾驶飞机的机载碰撞的动力响应。不仅要考虑风扇叶片的损坏，还要考虑由于压缩机芯的损坏而导致的发动机芯的推力损失。通过考虑不同的碰撞配置，不同的碰撞位置和不同的飞行阶段，研究了无人机在空降下的发动机损伤严重程度。风扇叶片的损坏和推力损失的百分比都被认为反映了无人机机载碰撞对飞机运行的影响。预期该研究可用于指导无人机空中碰撞的空中安全评估。风扇叶片的损坏和推力损失的百分比都被认为反映了无人机空中碰撞对飞机运行的影响。预期该研究可用于指导无人机空中碰撞的空中安全评估。风扇叶片的损坏和推力损失的百分比都被认为反映了无人机空中碰撞对飞机运行的影响。预期该研究可用于指导无人机空中碰撞的空中安全评估。
