Fundamental studies on MPD thrusters. Final progress report, April 1985-December 1986

Technical Report ·
OSTI ID:5073141
A theory was developed that predicts onset and erosion in MPD thrusters. The theory predicts onset currents that are in quantitative agreement with experiment. Erosion rates are predicted for a steady-state hot-cathode thruster. This theory is the first to model the viscous and thermal-electrode boundary layers in MPD thrusters. Stability criteria for diffuse-mode electrode current conduction were found.
