Reliability is a most critical system requirement and plays a vital role in space systems where risks associated with failure are very high, and hence, quantifying reliability becomes important. Liquid rocket engines (LREs) are an integral part of any space transportation system. Through rigorous hot testing and developmental flights, LREs are flight qualified during the initial phases. Once the LRE becomes operational, the reliability further grows as the system matures. In this paper, reliability growth is estimated for two sets of data, one with all flight engines for a particular LRE (LRE-1) and the other with flight as well as ground test data for a particular variant (LRE-2), using Crow-AMSAA model, and the values are compared using traditional binomial distribution methods at 60% confidence level (CL).
