摘要

This report results from a contract tasking Kurchatov Institute for the results of studying a stationary plasma-low power-thruster (SPT) and an ablative pulsed plasma one (APPT). In the first part of the Report the results of studying the module characteristic for a small SPT and for the thruster plume. In particular there are represented the description of test facility and system of thruster performance and plume parameter measurements as well as the results of these measurements. In the second part of the Report, the results of studying some features of the physical processes in APPT, as well as an analysis of the produced results based on the numerical simulation for increasing their efficiency, are represented. A two-dimensional model of APPT has been developed. lnterferometric investigations inside APPT discharge channel, piezoprobe measurements of dynamic pressure distributions and ultra high-speed photography with visualization of plasma flows have been carried out.
