Laser Heating for High Enthalpy Aerodynamic Test Facilities.
Abstract
A feasibility study has been made of the 'laser heated wind tunnel'. The analytical portion of the study indicates that it should be possible to achieve stagnation conditions of 10,000 degrees Kelvin and 1-2,000 atmosphere with laser powers of a few megawatts. Heat transfer at the throat is large, and will limit run time. An expreimental program initiated to study breakdown at high pressures, was of limited success due to state-of-the-art limitations on high power infrared window design. These limitations currently constitute the major unknown in assessing the ultimate success of the LHWT concept.
