Determination of Optimum Operating Parameters for the AEDC-PWT 4-Ft Transonic Tunnel with Variable Porosity Test Section Walls

Abstract

Tests were conducted in the AEDC Aerodynamic Wind Tunnel, Transonic (4T), to determine optimum operating parameters which minimize tunnel interference effects. The tunnel is equipped with inclined hole, variable porosity, test section walls. Pressure distributions on a 20-deg cone-cylinder model having a blockage ratio of 1 percent were used to select optimum test section wall porosity, wall angle, and tunnel pressure ratio through the Mach number range from 0.1 to 1.3.
