The Generalized Trajectory Simulation System. Volume 4. Numerical Operators

Abstract : The Generalized Trajectory Simulation (GTS) system provides a vehicle design and trajectory simulation capability. GTS is written in FORTRAN and is compatible with CDC 6000/7000 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 optimization, integration, and interpolation operators. Included with the description of each operator is a description of the input data required to execute the operators and recommendations concerning the types of problems for which each operator is best suited.
