A Combined Probe for Measurement of Mass Flow, Stagnation Temperature, and Stagnation Pressure in Supersonic Boundary Layers,

Abstract

A combined probe for measurement of mass flow, stagnation temperature, and stagnation pressure in supersonic boundary layers has been built and tested. The mass flow is evaluated from the rate of change of pressure in a volume connected to the probe. The probe incorporates a thermocouple and provision is made for the establishment of a controlled mass flow past the thermocouple during the temperature measurements. The probe has been tested at different pressures and temperatures in the boundary layer on the nozzle wall of the FFA Hyp 500 facilities. The results were compared with the results from simultaneous measurements with the AVA combined pressure-temperature probe. The results agreed within the expected limits of accuracy. (Author)
