Supplemental Calibration Results for the AEDC Propulsion Wind Tunnel (16T)

Abstract

Tests were conducted in the AEDC Propulsion Wind Tunnel (16T) to determine the centerline Mach number distributions and the corresponding tunnel calibration parameters. The tests were conducted over the Mach number range from 0.20 to 1.00. A quantitative evaluation of the effects of Mach number, tunnel pressure ratio, test section wall angle, and diffuser flap position upon the centerline Mach number distributions was determined by analysis of the local Mach number deviations and the longitudinal Mach number gradients. The results indicate that the centerline Mach number distributions are better than the wall distributions obtained during a previous calibration. For most operating conditions, the difference between the present centerline calibration and the previous calibration is considered negligible.
