RESPONSE OF A BURNING PROPELLANT SURFACE TO EROSIVE TRANSIENTS

Abstract

It was previously found that the heat release in the solid phase was associated with the driving process of unstable combustion. Since most of the propellants of interest are based on ammonium perchlorate (which has been shown to endow propellants with instability), it was considered necessary to identify the processes which could attenuate acoustic waves. A study of loss mechanism demonstrated that end losses are significant and enhance both axial and transverse stability. In the case of axial instability the enhanced heat transfer to the end closure was examined using heat transfer gages. Theoretical studies are continuing in an attempt to integrate combustion response to the gas dynamics of the cavity.
