Integrated modular engine (IME) system, a different propulsion system from today's conventional multi engine configuration, uses common manifolds to join all turbopumps and thrust chambers together. It has a capability of “component out” rather than “engine out”. The IME concept offers potential advantages of increasing reliability, improving operability, enhancing performance and lowering cost. In this paper, IME's applications and benefits are briefly described, and a comparison is made between...
