Test method of non-full loading firing dispersion for an airborne multiple launch rocket system

The non-full loading firing test method for airborne Multiple Launch Rocket System(MLRS) is studied. The new test method for reducing rockets consumption in dispersion test of airborne MLRS is presented. Applying the theory of launch dynamics and transfer matrix method of multibody system, based on the idea of equal initial disturbance, the launch dynamics model of airborne multiple launch rocket system is built, and the equations of vibration characteristics and dynamic response are deduced. Using random integer programming, the method for the reduction of rocket consumption in airborne multiple launch rocket system test s is presented. 6 tubes firing dispersion test scheme for a 19 tubes airborne multiple launch rocket system was presented using the proposed method. Using the new scheme, rocket consumption is decreased by 68.4%, and the test cost is reduced greatly.
