Abstract
The first-order second-moment reliability method is used to predict th e service life of rocket motors subjected to environmental temperature variations. All mechanical and thermal variables have statistical var iations and correlation between variables, specifically between streng th and modulus, as well as various distribution functions such as norm al, lognormal, and Weibull.
