CORRELATION OF WIND TUNNEL BLOCKAGE DATA

Abstract

An experimental investigation of the test section flow blockage characteristics was conducted at Mach 4 in the High Temperature Hypersonic Gas dynamics Facility. The models utilized in this program were pointed and blunted cones from 5 degree half angle to 90-degree half angle, flat plates, delta winged shapes, and hemispherical models, some of which were run up to 40-degree angle of attack. Comparison of the data with other facilities resulted in a correlation of the maximum model size compared to the potential flow core size with Mach number and drag coeffi cient for both open and closed test section con figurations for Mach numbers from 1.5 to greater than 10.
