The Generalized Trajectory Simulation System. Volume V. Weight Estimation Models for Sizing Applications.

摘要

The Generalized Trajectory Simulation (GTS) system provides a vehicle design and trajectory simulation capability. GTS is written in FORTRAN compatible with CDC 7000/6000 series computer systems. User-oriented input data specifications, computational efficiency, diverse program applicability, and convenient program modifications have been primary considerations in the design of the GTS system. The trajectory simulation capability can accommodate diverse types of vehicle configurations, flight profiles, and mission objectives. Additionally, the GTS system contains an extensive vehicle sizing capability and a state-of-the-art optimization capability. This volume documents the GTS library of weight estimation models which provide a vehicle sizing capability for space and missile vehicles that use solid propellant rocket motors. Liquid propelled vehicles can also be accommodated within the sizing procedure; however, they require the development of specialized weight estimation models to represent particular characteristics of the desired liquid propellant system. Primary applications include preliminary design studies, booster subsystem trade-off studies, and growth studies of existing systems, including the analysis of advanced propellant technology or new launch concepts.
