A RAPIDLY CONVERGING ITERATIVE TECHNIQUE FOR COMPUTING WIND COMPENSATION LAUNCHER SETTINGS FOR UNGUIDED ROCKETS

Abstract

The paper presents the development and evaluation of two algorithms for the determination of wind compensating launcher settings for unguided rockets. The algorithms are designed for use in an iterative trajectory simulation process and can be used to determine launch angles which will yield one of many possible trajectory objectives. One algorithm provides the first estimate as a function of the ballistic wind; the other controls the iteration. Four test cases are presented to evaluate the technique. Sixteen different wind profiles were applied to four separate unguided rockets. Two different trajectory objectives were considered - nominal burnout attitude and nominal impact. The tests show that the process converges rapidly, usually requiring only one or two iterations.
