Abstract
The wind tunnel test of two-dimensional airfoil is usually carried out in the special wind tunnel for the airfoil test, but this kind of wind tunnel is usually small in size and low in Reynolds number. On the contrary, the conventional wind tunnel test is generally large in size, in which higher test Reynolds number can be obtained, but there is wall interference and other problems to overcome at the same time. In this study, the RAE2822 airfoil was used to carry out the wind tunnel test of high-speed two-dimensional airfoil in FL-3, which is a large-scale conventional high-speed wind tunnel and the section pressure coefficient was measured. Experimental data after calculation and correction comparing with the standard model data shows that it is practically possible to carry out airfoil wind tunnel test in conventional high-speed wind tunnel.
