Transonic sting interference

Abstract

One of the problems that has to be solved in order to improve the accuracy of the results obtained in ground facilities is that of support interference, especially in regard to dynamic test data. While the dynamic sting interference has been well documented for hypersonic flow, it is generally only expected at transonic speeds in the cases where the body has a bulbous, dome-shaped base or a boattail. However, it is shown in the present paper that when boundary-layer transition occurs on the aft body, sting interference becomes a problem for all body geometries.
