Abstract
As an important part of the aircraft, the wing provides enough lift for the aircraft, but also creates additional drag. An effective wing design guarantees sufficient lift while minimizing the impact of drag on the aircraft. Aerodynamic analysis is an interdisciplinary research in the course of wing design. In this paper, the design of Magnus type is discussed by means of computational fluid dynamics. First, the airfoil with Magnus rollers was designed. Then, the key parameters such as rotational speed and Angle of attack are studied. Through the analysis of the line chart and calculation domain image of the calculation results, the results show that the installation of Magnus roller on the wing can effectively increase the lift and reduce the drag. With the increase of the rotational speed of Magnus Roller, the lift generated is larger. In the process of increasing the rotational speed, the reflux area behind the airfoil keeps decreasing until it disappears. It is proved that the Magnus airfoil can effectively avoid the phenomenon of airflow separation and avoid the stall of the aircraft. The conclusion can provide theoretical basis for the optimization design of the new generation aircraft airfoil.
