Abstract:

An earlier report presented a method for the numerical analysis of the dynamics of a small vehicle moving in a gravitational force field inside and outside a spherical, nonrotating planetary atmosphere. The method is based on an adaptation of the instantaneous conic concept and apart from computational advantages provides a simple and apparent physical understanding of the effects of atmospheric forces. It is the purpose of this report to give a detailed discussion of the application of the method and to elaborate the physical interpretation as a preliminary to the presentation in subsequent reports of the results of several hundred trajectories. These results will include the effects of coupled lift-drag modulation, acceleration limitation, temperature limitation during entry, multiple reentry and high eccentricity entry trajectories of a variety of realistic vehicle configurations.
