SOLID PROPELLANT COMBUSTION MECHANISM STUDIES
Abstract
Two composite solid propellant combustion experiments aimed at further elucidation of combustion mechanism are reported; one deals with burning surface photomacroscopy, the other, with low pressure combustion and oxidizer particle size influences on it. The first investigation involved photography of the surfaces of 1/4 inch square polysulfide-ammonium perchlorate (unmetallized) propellant strands during combustion in a coaxially-flowing nitrogen environment. Intense electronic flash illumination was used to render the luminosity of the flame photographically negligible, and the externallylighted surface was thereby viewed obliquely through the propellant flame zone at up to seven times magnification. The second investigation dealt with the dependence of the sub-atmospheric pressure burning rates of 1/4 inch square strands of ammonium perchlorate (polybutadieneacrylic acid and polysulfide, unmetallized) propellants on pressure and oxidizer particle size.
