SUMMARY OF INSTRUMENTATION DEVELOPMENT AND AERODYNAMIC RESEARCH IN A HYPERSONIC SHOCK TUNNEL

摘要

Analytical and experimental research devoted to devising, developing, and applying instrumentation and techniques to measuring aerodynamic forces and heat transfer rates on a cone at an angle of attack are reported. The development of a thin metal resistance thermometer mounted on an insulating body is summarized, and experimental heat transfer rates measured on a cone in the C.A.L. hypersonic shock tunnel are presented. An accelerometer balance system is described and experimental force measurements on a cone are also reported. A preliminary theoretical analysis of the flow about yawed cones at hypersonic speeds is reported.nThe flow uniformity in the test section and the time required for the flow about a model to become completely established have also been studied.
