A Comparison of an AEDC and a Russian Developed Pressure Sensitive Paint in the AEDC Propulsion Wind Tunnel 16T
Abstract
A comparison of a pressure sensitive paint (PSP) developed at Arnold Engineering Development Center (AEDC) with a PSP developed in Russia was performed in the AEDC Propulsion Wind Tunnel 16T. A Generic Wall Interference Model similar to an old AEDC model used to study wall interference effects was fabricated at the Central Aerohydrodynamics Institute (TSAGI) in Zhukovsky, Russia. The model has been tested in TSAGI's T-128 wind tunnel, and was sent to AEDC with the balance and sting support hardware for the 16T test. The AEDC PSP and the Russian PSP were applied to separate wings of the model. Conventional pressure, PSP, and force data were acquired simultaneously at Mach numbers 0.60, 0.85, and 0.95 while angle of attack was varied from -10 to 10 deg. The stagnation pressure and temperature were also varied to permit evaluations of the pressure and temperature sensitivity of each paint. Comparisons of the conventional pressure and PSP measurements are presented.
