Aeropropulsion Systems Test Facility Rake Calibration Test in Tunnel A.

摘要

A pressure test was conducted in the VKF Tunnel A to obtain calibration data on the APTU Free-Jet Nozzle Calibration Rake. The test covered the supersonic Mach number range of 1.76, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0, nominally, at a free-stream unit Reynolds number of 5.0 million per foot. The angle-of-attack range was -6 to +6 deg with typical roll angles of 0 and -90 deg. Model flow-field Schlieren photographs were obtained at all Mach numbers of 0 deg and positive angles-of-attack.
