A 1 MW radiatively-driven hypersonic wind tunnel experiment: Preliminary results Conference Paper uri icon


  • The results of recent experiments adding up to 800 kW of electron beam energy to a supersonic flow are reported. These experiments are intended to demonstrate the viability of the downstream energy addition concept as a solution to the run time and air quality limitations associated with hypersonic ground test facilities. An electron beam with energies up to 600 keV and currents up to 1.8 amps was directed into a supersonic air flow using magnetic steering and focusing fields. Pressure profiles along the nozzle and shadowgraph Mach angle images taken at 8 kHz indicate that flow properties are in agreement with CFD predictions.
