Plasma Influence on Characteristics of Aerodynamic Friction and Separation Lines Location
Abstract
This report results from a contract tasking Moscow Technical Company Institute of High Temperature RAS as follows: The contractor will analyze experimental plasma data already obtained on different aerodynamic shapes and produce an experiment at plate model. Three types of surface discharges will be tested in this work: HF multi-streamer discharge, micro hollow cathode discharge and glide surface discharge. The project objectives are 1) analysis of data from previous experiments; 2) preparation of experiment on a surface discharge plasma influence; 3) modification of test equipment: test runs in short operation wind tunnel; 4) report on analysis of experimental data. The technical parameters of the experiment are the following: Mach number- 0.1-0.4, 2.0; static pressure 50-240 Torr and 15 Torr; typical size of AD models 40-200 mm; kind of discharges, pulsed HF discharge; Micro hollow cathode; glide surface discharge. Operation mode of discharges pulse repetition and quasi-continuous. Repetition rate up to 10kHz. Mean input power of discharges 0.1-1kW. Operation time > 10 ms. The following parameters will be measured: gas temperature, Tg; surface temperature, Ts, ; static and stagnation pressure on a surface, Po, Pst, plasma energetic parameters; drag and lift forces. These parameters will be measured by means of the following diagnostic methods: electrical probes, Schlieren method, pressure transducers, optical spectrometer, tenso-balances, and high speed photo camera.
