Elevon Control Power Effective of VTOL Tail-sitter in Hover Mode
Abstract
The project aims to assess the control power and efficiency of the control surface at the trailing edge of tail-sitter VTOL called Elevon. It leverages the advantage of mitigating propwash induced flow from the propeller blowing pass into the control surface on the wings trailing edge to control its attitude. However, stability issues arise during the vertical hovering and in particular in landing phase. The investigation focuses on determining the optimal installation position of propeller, size of propeller, and size of control surface through laboratory experiments. The results showed the sizing of propeller 15inch and 33.3 percent C control surface gives the highest pitching moment. Testing with the wind coming from the trailing edge, the pitching moment can be reduced up to 50 percent during landing phase. While current achievements are confined to the laboratory experiments, those contribute to enhancing UAV and AAM platform efficiency.
