中文摘要: |
微型无人机呈现爆炸式增长,对民航飞机造成了极大的安全威胁。为探索微型无人机与鸟体对飞机结构碰撞损伤的差异性,本文开展市场上常见的消费级微小型无人机和等重鸟体对飞机风挡撞击的对比性实验。实验采用空气炮法,利用高速摄像观察两者撞击过程并测算撞击速度,对比实验后风挡损伤面积。研究结果表明,等质量鸟体和微型无人机在同等冲击速度下,由于无人机和鸟体组织构成不同,微型无人机的穿透力大于鸟体穿透力,速度衰减小于鸟体速度衰减,对风挡造成的损伤面积小于鸟体的损伤面积。所以微型无人机更容易穿透风挡对舱内人员和内部设施造成损伤,具备更大的破坏力。 |
英文摘要: |
The exploding growth of micro-UAV causes a great security threat to civil aviation aircraft. In order to explore the difference between the impact damage of micro-UAV and bird body on aircraft structure, a comparative experiment is carried out in this paper for the common consumer class micro-UAV and equal weight bird body impact on aircraft windshield. The experiment was carried out by air gun method. High speed camera was used to observe the impact process and calculate the impact velocity. The damage area of windshield is compared after the experiment. Experimental results show that under the condition of equal weight of both micro-UAV and bird body and with same impact velocity, due to their structure difference, the penetration force of micro-UAV is greater than that of bird body, and its velocity attenuation is less than that of bird body. The damage area of windshield caused by micro-UAV is smaller than that of bird body. So micro-UAV is easier to penetrate the windshield and cause damage to people and internal facilities in the cabin, and has more destructive power. |
