    Abstract

    A methodology to correct for the temperature effects of pressure sensitive paint data in a blowdown wind tunnel has been suggested. PSP measurements using Optrod-B1 paint were made on an aircraft model instrumented with thermocouples and conventional pressure taps. The tests were made at freestream Mach numbers of 0 .6 and 0.8 and at model incidences of 6° and 10°. The temperature correction is based on a mean model temperature concept for a given blowdown and the corrected PSP data is validated using pressure port data. It has been found that the accuracy of temperature corrected PSP results is as good as those obtained at transonic speeds in other tunnels elsewhere.
