A CHECK CALIBRATION OF THE AEDC-PWT TRANSONIC MODEL TUNNEL

Abstract

A brief investigation was conducted in the PWT Transonic Model Tunnel to check the validity of previous calibration results for two commonly used test section configurations. Static pressure measurements were made along the tunnel centerline and along the centerline of the top wall of the test section; simultaneous measurements of stilling chamber and plenum chamber pressures were obtained. The results of this investigation showed that the previous calibration results for a test section having four perferated walls was still correct, but previous results obtained with two perforated and two solid walls did not agree with those obtained in this investigation. This disagreement was felt to be caused by refinements in wall fabrication techniques and inaccuracies in the instrumentation used for the earlier investigation.
