RESULTS OF THE 1 MW RADIATIVELY-DRIVEN HYPERSONIC WIND TUNNEL EXPERIMENTS

The results of experiments involving the addition of over 800 kW of electron beam power injected into a supersonic air are reported. Using externally applied magnetic fields, a high-energy electron beam was directed and focused into a nozzle sustaining supersonic airflow. The experiments were undertaken to denJonstrate that downstream energy addition could be a viable solution to the limitations on run time and air quality that are encountered by hypersonic ground test facilities. In this work the total enthalpy of the flow was increased by a factor of -3, an amount similar to what will be required for a full scale Mach 12 facility.
