N-STAGE GUIDED DYNAMICS SIMULATION,

Abstract

The N-Stage Guided Dynamics Program is designed as a general tool for three-dimensional trajectory simulations. The sequence of in-flight discrete events, such as stage terminations, and the parameter changes at discrete points are input for the configuration. The number of allowable discrete events in a trajectory is limited only by the amount of storage available for input; which, considering the size of the 709 and 7090 machines, presents virtually no limitation. Present options make it possible to simulate most of the common ballistic impact, orbital, and space probe configurations. Computational considerations of the program include longitudinal drag, aerodynamic normal force, thrust acceleration and weight flow. All forces are applied to a point-mass missile in a twobody gravitational system. Missile attitude control may be obtained from precomputed tables, drifts, instantaneous turns or options for computed pitch commands. The dynamics simulation will accept and apply guidance program commands for attitude control and stage termination.
