Abstract: An optimal fire distribution method based on distributed firing efficiency evaluation is proposed to improve the firing efficiency of a rocket launcher. The models of firing efficiency evaluation and fire distribution are established. The mean relative damage area is considered as the index of firing efficiency evaluation, and the maximal firing efficiency is considered as the object function. The firing point and coordinate could be calculated by integrating the microgrid of area target. Two firing methods, i.e., single point firing and distributed multi-point firing, are designed for the calculation of firing efficiency. The calculated results show that the firing efficiencies of both methods increase with the increase in ammunition consumption, and the firing efficiency of optimal fire distribution method is 17.28% higher than that of single point firing method.
