【 摘 要 】

The effect of aspect ratio on the airfoil performance is investigated for airflow about axiallysymetric wings as a function of the angle of attack. The magnitudes of aerodynamic forces andmoments on airfoils resulting from the incompressible viscous flow fields are determinedexperimentally. The TE54 wind tunnel used for the experiments is an open conduit and has a 300x300mm x-section with a closed test chamber. The TE81 digital measurement device is used which hasthree components. Three different types of airfoil profiles are tested under the airflow speed of 33.76 ms^-1 and it is concluded that the airfoil with the aspect ratio of 2.761 yields the optimum performance.
