Abstract:
In order to improve the firing dispersion of Long Range Multiple Launch Rocket System ( LRMLRS) by reducing the initial disturbance,the rocket initial disturbance of a simple control LRMLRS is theoretically and numerically researched. The traditional concept of the rocket initial disturbance is expanded by using a launch dynamics theory. The equations of the rocket initial disturbance of the simple control LRMLRS are developed. The rocket initial disturbance and the firing dispersion of the simple control LRMLRS in control and without control are simulated. The simulation results are validated by experiments. The simulation results show that the rocket initial disturbance is still the main influence factor for the firing dispersion of the simple control LRMLRS. The results can provide references for reducing rocket initial disturbance and improving the firing dispersion of a simple control LRMLRS by optimizing simple control.
