Application of Linearized Transonic Theory to Tunnel Blockage Interference

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.
