Numerical Simulation Analysis on Repairing Hole of UAV Wing

Abstract:

Parachute recovery of UAV is often caused of holes and other injuries on wings, that are required repair and maintenance. The surface of the patch will form the high stress area, that affects UAV using life and safety .But repair method is good or bad directly affects size of the high stress area. Based on finite element method, the broken hole repairing method was formulated and validated by ANSYS. The method could minimize the high stress area as far as possible, and economically repair broken hole of wing in certain precision and safety standards condition. It has a certain reference value for UAV repair and management, and has reference significance for extending the service life of the UAV. Key words: Finite element method; Unmanned Aerial Vehicle (UAV); Simulation; Hole of wings
