Pagination or Media Count:
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.
