    Abstract

    A probe - traverse - mechanism is developed to measure flow parameters, static pressure, total pressure, total temperature, and flow direction behind blade rows in rotating turbomachines. The mechanism would position the probe, in various axial locations, at different radial 88 well 88 circumferential positions, with in wi11 acceptable accuracy margin, aligning itself automatically along the flow. The mechanism would position the The calibration of the mechanism shews a radial traversing accuracy of 0.001 inch and a yav probe nulling of the order of 0.15 degree in a range of 4quot; of rapid traverse. A discussion of various flow measurement probes designed to Built the requirements of the Transonic Compressor Research Rig is also included as a13; appendix.
