N2 - For the problems that the fixed-time opening of the cargo delivery projectile for dispersion of the bullet is influenced by the distribution of the trajectory of the carrier projectile, and the central distribution of the bullet cluster is large while the coverage rate of the bullets for the target is low, simulation and analysis were performed for different opening time control strategies and the advantages and the weaknesses of these strategies were compared .On the basis that the opening time is corrected by the opening control strategy that the horizontal distance of the opening points of the carrier projectile is constant, A method was put forward utilizing the relationship between trajectory elements deviations and the falling point range of the bullet to perform the second correction of the opening time, and a simple algorithm was given for predicting the trajectory parameters and for calculating the correction time. It was proved from the Monte Carlo method that the central distribution error of the bullet cluster can be reduced about 83 percent compared with the fixed-time opening control method, moreover, the algorithm has the advantages of small calculation quantity and easy realtime realization.
