| Abstract: | The ablation mechanism and the performance of carbon-phenolic material of solid propellant rocket nozzles are studied. The influences of chemical reactions, particle impingement and the shear stresses in boundary layers on the recession process are also analysed and calculated in this paper.Based on the comparison of experimental results with the predicted ones, an empirical correlation to predict the total recession including both chemical and mechanical effects is developed. |
