Wall Interference Effects on Elliptic Missile Body Configurations in Tunnel 4T

Abstract

Estimates of the test section wall interference effects have been computed for an elliptic missile body configuration in the Aerodynamic Wind Tunnel (4T) of the Propulsion Wind Tunnel Facility. Results are presented for test Mach numbers of 0.95 and 1. 05. Comparisons of test section wall static pressure measurement in 4T with computations show relatively good agreement at Mach 0.95 and follow the general trend at Mach 1. 05. The wall interference produces a 2.5% decrease in 1 i ft coefficient at the highest angle of attack for which calculations were made.
