Abstract:

Wind tunnel blockage interference is calculated by the application of linearized transonic theory. The linearized transonic perturbation equation is solved by the Fourier transform technique to obtain blockage interference in a perforated transonic wind tunnel in terms of pressure coefficient. The calculation has been used to determine the applicable Mach number range of subsonic tunnel corrections. An application to a circular arc airfoil is presented to demonstrate the accuracy of the blockage correction.
