Analysis of a Liquid Rocket Combustion Chamber Cooling

This paper analyzes the ablation in a liquid rocket combustion chamber´s high altitude simulation tests. Based on the characteristic of combustion chamber and the history of the malfunction, our proposed corrective measure of the chamber and relevant product reliability validation tests were conducted. The validation tests showed that our corrective measure is feasible and relevant reliability met our requirements. The investigation of purchased products should start during the phases of product manufacturing, especially for the design of combustion chamber cooling.
