Test Section Temperature Calibration of the AEDC PWT 16-Ft Transonic Tunnel at Stagnation Temperatures From -30 to 30F
Abstract
Tests were conducted in the Propulsion Wind Tunnel, Transonic (16T) of the Propulsion Wind Tunnel Facility to determine the test section temperature distribution and calibration relationship to a mean nozzle reference temperature while using a cryogenic cooling system to produce stagnation temperatures from - 30 to 30F. Data were obtained over the Mach number range 0.20 < or = M < or = 0. 55 for subsynchronous operation and 0.55 < or = M < or = 1.2 for synchronous operation. The temperature deviation in a 6- by 6-ft core was found to be less than plus or minus 8F in the stagnation temperature range -30F < or = T sub t < or = 30F. It was also determined that an offset calibration factor of -2F must be applied to the mean nozzle reference temperature to obtain the average test section temperature in a 6- by 6-ft core.
