EXPERIMENTAL STUDIES OF HIGH TEMPERATURE HYPERSONIC DIFFUSERS

Abstract

The effect of various diffuser configurations and blunted cone models on tunnel blockage and pressure recovery of a high temperature hypersonic gasdynamics facility is presented. These studies were conducted in the RTD One- Megawatt Prototype Electrogasdynamic Facility operating continuously with dry air. All data were obtained with frozen flow at Mach number 7.6, a stagnation enthalpy of 3000 BTU/lb, and an arc chamber pressure of 7 atmospheres. To determine the effects of extreme air temperature, the total enthalpy was varied to 6000 BTU/lb with one diffuser configuration.
