Simulation research on improving precision of a certain type of laser guided aerial bomb

In order to improve the precision of laser guidance, it is necessary to analyze the degrading effects of various factors on precision of laser guidance of a certain type of aerial bomb. We now present our simulation research results on such degrading effects with a view to improving the precision of a certain type of laser guided aerial bomb. In the paper, we explain in detail our simulation research results. The mathematical model of various factors influencing guidance precision and the method of calculation are proposed. The characterises of laser guidance, the effect of imperfect bomb release, the effect of the vicissitudes of flow field on aircraft, and the effect of imperfect laser tracking of target are presented. The numerical simulation results for a certain type of aerial bomb are given. Such simulation already took into consideration the degrading effects of the above-mentioned four factors. The results indicate preliminarily that this type of aerial bomb as originally designed can satisfy the design requirements on precision under typical release conditions.
