Approximate Equations for Evaluating the Impact Dispersion Resulting from Reentry Winds and Deviations in Density.
Abstract
The effects on impact dispersion of winds and density deviations from a standard atmosphere are usually determined by a three- or six-degree-of-freedom trajectory simulation. However, for preliminary design studies and for implementing targeting corrections for wind and density effects, approximate equations for evaluating impact dispersion are required. The necessary equations have been derived and are presented herein. Impact errors computed using the simplified equations are in excellent agreement with three-degree-of-freedom simulation results for the types of trajectories used for current long-range ballistic missiles.
