Abstract
A single-stage-to-orbit launch vehicle is used to assess the applicability of Soviet Energia high pressure hydrocarbon engines to advanced U.S. manned space transportation systems. Two of the Soviet engines are used with three Space Shuttle main engines. When applied to a baseline vehicle that utilized advanced hydrocarbon engines, the higher weight of the Soviet engines resulted in a 20 percent loss of payload capability and necessitated a change in the crew compartment size and location from mid-body to fore-body in order to balance the vehicle. Various combinations of Soviet and Shuttle engines were evaluated for comparison purposes, including an all hydrogen system using all Space Shuttle main engines. Operational aspects of the baseline vehicles are also discussed. A new mass properties program entitled Weights and Moments of Inertia (WAMI) is used in the study.
