Maneuvering engines for Space Shuttle Orbiter.

Review of the orbit maneuvering system, i.e. the propulsion system which is to provide the thrust for all major maneuvers while the shuttle orbiter is functioning as a spacecraft. The design and operational philosophy of the shuttle vehicle and orbital maneuvering system are discussed, along with the selection rationale for the current baseline orbit maneuvering system. Critical development issues and potential design alternatives are examined.
