THE PREDICTION OF HEAT TRANSFER AND ABLATION IN THE AFT-CLOSURE OF A SOLID PROPELLANT ROCKET MOTOR

Abstract

A mathematical design model has been developed for the prediction of insulation requirements in the aft-closure of a solid propellant rocket motor. This model and the associated calculation technique represent only a first approximation to the exact solution of a problem concerned with various complex phenomena. The behavior of ablative elastomeric insulation materials in such an application is considered. The choice of the assumptions used to calculate the forced convective and radiative heat fluxes is based on recent experimental results. A summary is made of the information still to be determined in order that this model can be fully utilized.
