03.4 - Applied AerodynamicsAPPLICATION OF HIGH-ROBUSTNESS BEMT FOR SIMULATION OF UAV-VTOL PROPELLER AT LOW/HIGH ADVANCE RATIOZ. Fan¹, Z. Zhou¹, X. Zhu, Science and Technology on UAV Laboratory, NPU, China; ¹School of Aeronautics,Northwestern Polytechnical University, China For VTOL propeller design, lots of nonlinear effect should be considered such as low-Re, transonic and large AOA effect. When considering the propeller-wing interaction in the design, the flow details of the propeller should be obtained. In this paper, an improved BEMT is derived for nonlinear wide-range propeller analysis and able to obtain the blade circulation at both low/high advance ratio. |
