TRAJECTORY ERROR ANALYSIS COMPUTER PROGRAM FOR TWO-DEGREE OF FREEDOM TRAJECTORIES

Abstract

Estimates of the cumulative error associated with the third-order Runge-Kutta solution of the two degree of freedom equations of motion are presented. These estimates constitute a simple, but not rigorous, approach to automatic increment selection. Details of the computer program TEA-2 which utilize these equations are described. Sample calculations are included. TEA-2 is between 2.0 and 1.7 times faster than the previous trajectory program in addition to providing greater consistency and reliability.
