Effects of trailing edge thickness on the aerodynamic characteristics of NACA symmetric airfoil

摘要：

　　In this paper,a study on the analysis of the effects of trailing edge thickness on the aerodynamic characteristics of an airfoil is described.In this research,modification of the formula representing NACA symmetric airfoil is studied to change the airfoil shape with different trailing edge thickness of users choice.According to the result of aerodynamic characteristics,as the trailing edge thickness increases the maximum lift coefficient increases while the lift-to-drag ratio decreases.In this paper flow calculation results are demonstrated and the analysis on those results and findings on the effects of non-zero thickness of trailing edge are suggested.
