Research progress of collision safety characteristics of civil light and small UAVs

Light and small civil UAVs induced accidents happened frequently, such as injuring people by colliding and interfering, even crashing into commercial aircraft, which made the UAVs collision safety a research hotspot by scholars from all over the world. This article analyzed the collision safety risk incentives in the operation of light and small UAVs. Based on two UAVs collision scenarios where drones collide with civil aircraft and people, this paper summarized the collision safety analysis and test methods of light and small UAVs, as well as the collision safety criteria and the damage classification approach. Finally, the collision safety research development of light and small UAVs is prospected.
