Abstract:

Hypersonic missiles re-entering the atmosphere are subjected to severe aerodynamic heating. In order to closely simulate these severe thermal conditions for testing laboratory models, a program was undertaken which consisted of the design, construction, and testing of 1 an airstabilized ac arc, and 2 a vacuum and cooling system to evacuate the high-temperature plasma generated by the arc. Stable and reliable operation was achieved with the ac powered arc, but it was relatively inefficient in utilizing the available power. The vacuum and cooling system to receive, cool, and exhaust to the atmosphere the plasma generated by a 1.5-megawatt airstabilized dc arc makes testing possible with a low-density plasma and subatmospheric stagnation pressure and permits the heat flux to be adjusted independently of the enthalpy difference.
