THREE DEGREES-OF-FREEDOM TRAJECTORY ANALYSIS PROGRAM
Abstract
The translational motion of a multi-stage missile with respect to a non-rotating spherical earth, with a 1/R squared gravitational field nd a real atmosphere was programmed for the 7090 hig sp ed digital computer. The program includes the effects of aerodynamic lift and drag, booster thrusting, and spin due to aerodynamic fins and spin rockets. Th output fro the program includes the trajectory of the vehicle with respect to both inertial space and earth fixed coordinates, the velocity and total acceleration time histories of the vehicle and the laminar and turbulent heat transfer at the vehicle's stagnation and sonic points r spectively. In addition the resul s of a run ic simulates the Trailblazer II trajectory are presented. Provisions were made to determine the range, azimu l vation and their first and second derivatives for the vehicle from any point in space. Incremental valves during stage separations may also be found. These computa ions are performed in an auxiliary program entitled Radar Trajectory. (Author)
