Abstract:

The six-degree-of-freedom equations are developed for a ridid body re-entering the earths atmosphere. These equations are normalized to aid in their systematic study. Their solution by means of both analog and digital computers was demonstrated. The results for specific re-entry conditions are shown together with an analysis of the errors in impact position due to re-entry perturbation sources. For the case of proper time scaling, the results of analog and digital computers compare quite favorably. Author
