Abstract : The transient combustion analysis developed under this program is compared with other treatments. Earlier analyses have failed to predict the observed effect of surface exotherms on combustion instability, whereas the SRI treatment is consistent with the observations. It is shown that this difference arises from the method of treating surface reaction kinetics in the solid propellant combustion model. Also presented are initial experimental observations based on a fiber-optic technique for viewing the burning propellant surface. These observations provide illuminating information concerning the ammonium-perchlorate deflagration at the surface and give a clear indication of the flame-zone thickness. (Author)
