A Mass-Fow Probe for Measurement in High-Enthalpy Supersonic Boundary Layers,

Abstract

A system for mass-flow measurement in supersonic boundary layers has been examined. The mass flow is evaluated from measurements of pressure derivatives in a closed volume under controlled temperature conditions. Measurements of boundary-layer properties have been made with the probe side by side with the AVA combined pressure-temperature probe in the FFA Hyp 500 wind tunnel. The mass flows measured with the new system were compared with the mass flows calculated from measurements of stagnation temperature and stagnation pressure with the AVA probe. The results agree within the expected limit of accuracy.
