Abstract:

OUTLINE Examples of micro propulsion ablative devices Fundamentals of ablation Detailed analysis of specific devices Micro-Pulsed Plasma Thruster -- Micro-Laser Plasma Thruster -- Micro-Vacuum Arc Thruster SUMMARY Various microthruster technologies based on ablative mechanism were developed. Self-consistent modeling approach for ablative micro-thrusters was formulated based on a kinetic ablation model and particle plume simulation. Most extensive validation of the modeling approach was performed for micro-pulsed plasma thruster. Plasma density, surface temperature, ablation rate, ablation profile were compared with experiment. Optimization criteria were formulated for some devices, such as microPPT.
