Elevon Control Power Effective of VTOL Tail-sitter in Hover Mode
Abstract
Tail-sitter vertical-takeoff-and-landing concept has been introduced since the 1920s and the studies have been continued in form of unmanned aerial vehicle proposes. This research is proposed as the success of tail-sitter VTOL UAV inspired to enlarge from level of unmanned to manned vehicle. The purposes is to examine the control power and efficiency of the control surface at the trailing edge of tail-sitter VTOL called Elevon (the specific-designed control surface that can perform control like both elevator and aileron). This study will focus on only three significant phases of aircraft mission that are takeoff, hovering, and landing. The elevon could provide control power differently in each scenario due to the differences in thrust power, wind condition, or thrust angle. The research will be based on wind tunnel testing with the dedicated model to investigate the effect of each relevant parameters. The analysis of data collection from the test will turned into the relationship of the parameters and the output. The results could show how the sizing of propeller and control surface, wind direction, or tilt thrust angle affect the control power and efficiency of the elevon in different numbers of parameters. The analyzed data are the precious fundamentals for the optimization of tailsitter VTOL design to reach its maximum efficiency in control, especially for future manned-size tailsitter development.
