Abstract
A gas turbine engine includes a compressor, a combustor and a turbine. A compressor section has an exit upstream of the combustor. A temperature probe extends through a compressor exit housing surrounding the compressor section exit. The temperature probe taps air downstream of the exit into a probe body having a passage leading to a temperature sensor. There is a controlled leakage also allowing air from within the compressor exit housing to leak. A method and a test probe are also disclosed.
