【 摘 要 】

In the present work, it's proposed to study the aerodynamic characteristics of the S9023 airfoil for the various angle of attack with different Reynolds number. With a view to extending the knowledge of the aerodynamics of pressure distribution and lifting surfaces over S9023 airfoil has been measured in a low-speed subsonic wind tunnel. Experiments were carried out by varying the angle of attack, from 00 to 150 and the Reynolds number ranges from 1.3 X 105 to 4.5 X 105. The lift coefficient and drag coefficients for S9023 airfoil are obtained by measuring the pressure distribution from the pressure ports which is situated over the airfoil surface. The aerodynamics parameters at different Reynolds number is plotted i.e. Cp vs. x/c, Cp vs. y/c, Cl vs. α. Cd vs. α and L/D vs. α. The non-dimensional aerodynamics characteristics for S9023 2D airfoil described in details for different Reynolds number.
