Space Shuttle Orbiter

Abstract This article gives details on the preliminary design considerations involving the Space Shuttle. Basic requirements and effects on design had to be studied. Since the Shuttle was entirely different from any other spacecrafts, engineering teams had to be organized. The reusable main engine was a major advance in rocket engineering and development of the main engine is discussed. Orbiter specifications are given. Various orbiter systems include: Crew compartments, Guidance, Navigation control, Hydraulics, Auxillary power unit, Communications, Environmental control, Life support, Payload deployment, Payload retrieval systems. The first Space Shuttle vehicle was the Enterprise , and it was not intended to fly. The orbiter was launched from a Boeing 747. Columbia was the first Space Shuttle to be completed and flew for the first time in 1981. Space Shuttles have flown more than 100 missions. Many studies have been conducted to consider replacements for the Shuttle. No system has shown promise yet.
