DEVELOPMENT OF A TRACER-SPARK TECHNIQUE FOR THE STUDY OF HYPERVELOCITY FLOW FIELDS,

Abstract

A technique was developed for the mapping of velocity fields, with particular application to testing in a spark-heated hypersonic tunnel. Data were obtained in the form of photographs of sparks struck through the flow field under study. Instrumentation to initiate the sparks in the flow was designed and fabricated, and its performance has been studied analytically and experimentally. Velocity profiles were obtained in the empty test section with a high degree of success. Attempts to measure velocity profiles in wakes were not as successful, however. (Author)
