Abstract: The test method and simulation technology about the non-full loading firing dispersion for multiple launch rocket system (MLRS) are studied. A new method for reducing the rocket consumption in dispersion test of MLRS is presented. A parameterized simulation model of MLRS is established by use of the virtual-prototype-based dynamics simulation technology and multi-island genetic algorithm. The proposed model is integrated in the multidisciplinary optimization software ISIGHT. Based on the idea of equal initial disturbance deviation, a firing dispersion test method of a non-full loading MLRS is presented by using the multi island genetic algorithm as the optimization control strategy. The initial disturbance and firing dispersion are calculated via simulation in the case of full loading salvo and non-full loading continuous fire. The simulated results show that the two schemes have the same initial disturbance, and the system firing dispersion is satisfied with F test, which proves that the proposed firing dispersion test method with the non-full loading for MLRS is completely feasible. The rocket consumption in firing dispersion test of a MLRS can be decreased by 41.7% using the proposed non-full loading scheme. Key
