title = "DYNAMIC RESPONSE AND DAMAGE OF THE FAN BLADES DURING UAV INGESTION INTO AN AERO-ENGINE",
abstract = "Based on the potential risk of a drone striking on an aircraft, a numerical model is established on the finite element analysis software PAM-CRASH version 8.6 to simulate the collision between a small drone and full-scale fan blades of a typical turbofan engine. Parameter studies are performed on the impact orientation, location and kinetic energy, and all are proved to have different levels of effects on the fan's dynamic response. In order to investigate the different damage mechanics of hard and soft impact, a comparative study is also conducted between the bird and the Unmanned aerial vehicle (UAV) ingestion with the same impact energy. Results showed that the damage and failure of the fan blades induced by UAV collision is more intense than that by bird strike due to its features of local stress concentration and material failure. The research results provide a reference for the revision of the airworthiness standards for small drones and the exploration of the test research of UAV airborne collision.",
