Investigation of Thermal Fatigue in Non-Tubular Regeneratively Cooled Thrust Chambers. Volume 1

Abstract

An analytical method for predicting the thermal cycle life capability of nontubular regeneratively cooled thrust chambers was developed. Included in the method are the effects of time-dependent creep damage and strain range- dependent fatigue damage. The method was calibrated using material mechanical properties, isothermal fatigue, and tensile creep specimen data. Isothermal cyclic data on laboratory specimens to determine the effect of strain rate, temperature, strain range, and tensile and/or compression hold time on fatigue life of four candidate rocket engine thrust chamber materials was obtained. The experimental data and test procedure are presented. Also obtained was basic material data on the materials of interest.
