A TRAVERSING PROBE FOR PITOT-PRESSURE MAPPING IN A HYPERVELOCITY TUNNEL
STANFORD UNIV CA
An account is given of the design, construction, and operation of a multi-probed axially traversing pitot-pressure rake, which was designed to measure wake pressure profiles behind models in the Stanford sparkheated wind tunnel. Criteria considered in the design of the traversing probe are discussed. The mechanical operation of the probe during bench tests and during initial experiments in the tunnel is described, and velocity-time diagrams are given. Examples of the pressure data that have been taken in the wake behind a cylindrical model are presented and discussed briefly.
