Abs_act A study was performed to evaluate the reliability of Integrated Modular Engine (IME) concepts. Comparisons were made between networked IME systems and non-networked discrete systems using expander cycle configurations. Both redundant and nonredundant systems were analyzed. Binomial approximation and Markov analysis techniques were employed to evaluate total system reliability. In addition, Failure Modes and Effects Analyses (FMEA), Preliminary Hazard Analyses (PHA), and Fault Tree

The required number of valves for the IME is 66, with 4 valves for each thrust chamber, fuel turbopump and oxidizer turbopump, plus 2 turbine bypass valves. Details of this IME design are provided in reference 5.
