Dispersion Simulation Technique of Multiple Tube Weapon

It is very important to simulate the precision of fire of Multiple Launch Rocket System (MLRS) for improving the dispersion and for reducing the number of rockets used in test. Launch dynamics of MLRS is deeply studied both in theory and through test from the view point of whole system including rockets, launcher, propellant and envirment. The launch dynamic equations of multibody coupling rigid bodies and elastic bodies of MLRS are established. The dynamic response of MLRS is analysed by using transfer matrix method of multibody system. The dispersion simulation technique of multiple tube weapon is established based on the launch and flight dynamic equations by using Monte-Carlo method. The dispersion of a MLRS and the programming test scheme to reduce rocket consumption in the MLRS test are simulated. The results of simulation are verified by test.
