Numerical Study of Dynamic Ground Effect of a Carrier-Based UAV

Abstract:

The paper uses computational fluid dynamics combined with sliding mesh and dynamic layering methods to study the dynamic ground effect of a UVA during the phase of takeoff. The research focused on longitude characteristics, such as lift, drag and pitching moment. Results showed that the aerodynamic force would vibrate acutely, which affected the stability of the UAV and the safety of takeoff. Pitching angle is the most important factor influencing the aerodynamic forces. Increase the pitching angle properly is benefit to the safety of takeoff operation.
