Abstract:

The operation of an xisting subatmospheric plasma arc facility was characterized to assist the user in selecting the proper simulation conditions for materials test application. Eight principal test conditions were established within the operating limits of the arc, and the pertinent parameters describing the thermal environment were determined and tabulated. Subsequently, the hypersonic re-entry conditions corresponding to the thermal environment of the test conditions were computed and plotted on a velocity-altitude chart. In addition, an arc unit with water-cooled, non-consumable electrodes was developed to reduce contamination of the arc plasma. This arc, having double-ring electrode configuration, will generate plasma with a net average enthalpy of 8000 Btulb. The final phase concerned testing various materials under different exposure conditions. Author
