INTENTIONAL COMBUSTION OSCILLATIONS IN PROPULSION SYSTEMS.

Abstract

Combustion oscillations for the improvement of the 'conventional' MHD open cycle may be used. The resulting pressure modulation of the plasma can circumvent the sigma-e(U sq.) limitation of the classical generator by the possibility of increasing both conductivity (sigma-e) and gas velocity U over that of the steady flow case. The conductivity amplitude (delta-sigma)/sigma-eo was measured experimentally and plotted against the pressure amplitude (delta P)/P for a vortex MHD generator modulated by the first order travelling tangential mode of combustion oscillation.
