Abstract
Starting from the propeller design, a favorable propeller slipstream form was obtained by designing a suitable propeller to improve the aerodynamic characteristics of the wing in the propeller/wing configuration. The propeller slipstream was controlled by changing the radial thrust distribution of the propeller. A method of propeller design based on the given thrust distribution was proposed and the feasibility of the method was verified. Propellers designed with minimum energy loss and different thrust distributions were applied to multi-propeller/wing configuration, so as to study the effect of the propeller on the wing. Results showed that changing the propeller force distribution can change the propeller slipstream, which in turn changed the aerodynamic characteristics of the wing. The propeller with a gentle thrust distribution can increase the lift and reduce the drag on the wing, despite of its efficiency decrease. And compared with the minimum energy loss design results, the lift-drag ratio can be increased by 9.94%.
