Damage and Failure of Aeroengine Blades Under Small UAV Impacts
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.Unmanned aerial vehicles (UAVs) may collide with vulnerable parts of other aircrafts, such as engine blades, causing accidents. The research on small UAV impact is limited. Besides, UAV impact with propeller and rotor blades is poorly understood. In this paper, a finite element (FE) model of a UAV with a weight of 4.78 kg, turbofan blades, propeller ...
