Proof of principle energy addition experiments for the RDHWT/MARIAH II hypersonic wind tunnel
- View All
Lasers and electron beams have been used to study radiative energy addition to supersonic flow as part of the radiatively driven hypersonic wind tunnel (RDHWT)/Mariah II program. Over the last three years this extensive test program has provided proof of principle demonstrations of supersonic energy addition as well as characterization of the resulting radiatively heated flow properties. This paper discusses the three major experiments that have been performed in support of this program, including the experimental design, and characterization of the flow and the radiative sources used. These proof of principle experiments consist of a laser and an electron beam energy addition at the 10 kW level and a more recent 100 kW electron beam experiment. Where possible, these results have been compared with both I-D and 2-D CFD models. © 2000 by the American Institute of Aeronautics and Astronautics, Inc.
