Computer Program for Simulating the Six-Degree-of-Freedom Motion of Missile Debris Fragments

摘要

The rational modeling and empirical correlations used to build a comprehensive computer code for simulating general six-degree-of-freedom motions of missile debris fragments are described. The approach is deterministic in that a number of possible generic fragment shapes were defined, methods were selected to describe the aerodynamic loads on these shapes, and the results were incorporated in a six-degree-of-freedom trajectory program. The method chosen is simple enough to avoid large computation times and yet represents coning and tumbling conditions as well as trimmed flight. (Author)
