某高速无人机飞行事故分析:高速无人机控制失效分析及控制参数匹配

Accident Analysis of One Type of High-Speed UAV:Control Action Invalidation and Control Parameter Match of High-Speed UAV

某型高亚声速无人机连续出现两起飞行事故,在基本排除了机载设备故障的原因后,针对飞行控制失效的原因展开了深入的理论分析与飞控系统仿真试验,最终确定故障原因是在大飞行动压情况下,该型无人机控制参数出现不匹配。这为该型无人机以后的正常使用提供了理论依据,也为其他高速无人机的研制和使用提供了借鉴经验。采取相应改进措施后,后续该型无人机放飞取得成功。

One type of subsonic unmanned aerial vehicles（UAVs） has continuously taken place two accidents. After eliminating the possibility of the equipment went blooey, the reason of the control action invalidation by theoretical analysis is searched and simulation. Finally, the reason is that the control parameters do not match under over much dynamic pressure. It provides a theoretical basis for normally use the type of UAV and experiences for developing other high-speed UAVs. By using the improved measures, the type of UAVs is more success for the sub-sequent flight.
