A Study of the Effects of Electric Fields on Solid Propellant Burning Rates
Abstract
An experimental study, guided by theoretical considerations, was made on the effects of electric fields on burning rate of two metallized composite propellants. Mechanisms causing observed burning rate changes were sought. Experimental data include flame elctron number densities, electrical conductivities, electric field strengths, electric currents, combustion efficiencies, exhaust emissions spectra and continuous measurement of burning rates. Results show that burning rate increases are due to current heating of the nonburning propellant and that burning rate decreases involve flame electrons, causing inhibited combustion under proper voltage conditions. Non- collective reactional interference was inferred for this latter case.
