Study on range correction coefficient arithmetic of attitude-stabilized rocket projectiles

A range correction method of attitude-stabilized rocket projectiles is introduced, which will enhance the longitudinal compactness of rocket projectiles through adjusting deployment time of the drag device. Aiming at improving the traditional RCC arithmetic, a regression arithmetic based on random sample is put forward. In random sample arithmetic, more factors of range are taken into account and the statistics optimization is deduced. But the approach requires much more computer time, therefore it is disadvantageous to the rapid reaction of the artillery rocket weapon system. By adopting the experiment design technology, the RCC fast arithmetic is put forward based on orthogonal design or homogeneous design in which the factors and their levels are arranged according some regulation. The computer time for fast arithmetic is comparable to traditional one, and the accuracy is a little inferior than that of random arithmetic but much better than that of traditional arithmetic.
