Influence of Damage Degree of UAV Propeller on its Dynamic Parameters

The propeller is the primary propulsion source for some UAVs. When damaged by external factors, the dynamic parameters change significantly, affecting the flight's stability, controllability, and safety. Using theory and fluid simulation, the dynamic performance parameters caused by random blade fractures are calculated. These parameters are measured using a propeller lift test platform to assess the propeller's condition. Observing parameter changes at different damage levels provides a reference for the continued use of damaged propellers.
