Abstract

The performance of airfoil plays an important role in the performance of model aircraft. Three types of airfoils are selected in this paper: the GOE 480, MH 114, and MH 115, which are all flat-convex airfoils. Firstly, three types of airfoil were numerically analyzed by using Profili software. The results show that among the three types of flat-convex airfoils, the lift-drag ratio of MH series airfoils is higher than that of GOE 480. Then, the FEA software was used to analyze the aerodynamic performance of the wings. And the lift and drag coefficient obtained from calculation was compared with the results by Profili software. To compare the actual flight performance of the three airfoils, the control variable method and UAV self speed measurement method based on sequence images were used for the real field test. The results show that the type of MH 115 has the largest max level speed among the three types of wings.
