드론 날개의 형상에 따른 유동 성능에 관한 연구

Abstract

In this study, the flow rate at the drone and the pressure around the drone were investigated by carrying out the flow analysis due to the wing shape of drone. At models 1, 2 and 3, the positions of areas with the maximum flow rate around the drone according to the shape of the wing were seen to be same at the rear wing of drone. Model 2 has the fastest flow rate, followed by model 1 and model 3. At the distribution of flow pressure by model around the drone according to the wing shape of drone, models 1, 2 and 3 had the same highest pressures at the center of drone. In comparison with the maximum pressures of models near the wing shape of the drone, the flow pressure at model 2 was higher compared with models 1 and 3. At the wing shape of the drone, model 2 is considered to carry the flow performance better than models 1 and 3. So, the result of this study is thought to be useful for designing the wing shape of the drone. Without the test of flow performance due to the shape of drone wing, the flow performance can be seen as the flow rate and pressure are investigated through the flow analysis.
