Unified Study of Plasma/Surface Interactions for Space Power and Propulsion.

Abstract

High specific impulse, high specific power devices, such as magnetoplasmadynamic arcjets, laser or microwave propulsion channels, and MHD generators, involve the flow of modest temperature (0.5 - 5 eV) partially ionized gases at speeds of 5 - 20 km/sec. The interactions of such flows with solid surfaces containing, channeling or penetrating the flow provide a principal source of concern for the efficiency and lifetime of high specific power systems. The present report describes a basic research effort that examines the plasma/surface interaction experimentally in an arrangement providing diagnostic access usually unavailable in mission-oriented, device-development projects.
