High Subsonic Airfoil Test Technique on Flexible Adaptive Wind Tunnel

In this paper,a new iterative testing strategy is described for two dimensional model testing in transonic flexible adaptive wall wind tunnel by using the transonic small perturbation equation to com- pute the exterior flow fields.According to this strategy,experiments had been done in Northwestern Polytechnic University high speed flexible adaptive wall test section with a NACA0012 airfoil with 8%of block- age. The experimental results agree well with the interference-free data by large wind tunnel abr oad.Another strategy is also described in this paper,that is one-step method. The streamlined wall shapes computed by the two strategies are compared and found that they agree well,with each other.The study in this paper displays good prospects that the two strategies could apply to future transonic airfoil test.
