摘要

An airborne collision between civil Unmanned Aerial Systems (UASs) and manned aircraft is a potential threat to the aircraft operation safety. In this paper, a structure level UAS collision ground test was performed on a commercial airliner horizontal stabilizer section to investigate the dynamic response of this primary operation component. The projectile was a 3.4 kg quadcopter named ‘Inspire I’. Explicit dynamic code PAM-CRASHR was employed to simulate the collision process and the modeling procedures were modified through comparison with test data, followed by series of simulations to assess the hazard of different collision scenarios. The results showed that 3.4 kg drone impact at the airliner cruising speed could cause some damage on the horizontal stabilizer front spar and the situation is more serious than 3.6 kg bird strike in which the hardness of drone components rather than kinetic energy is a decisive factor. The lithium-ion battery penetrated into the airframe had a smoke sign in the test, which might be a potential ignition source.
