Ballistic Trajectory Extrapolation and Correction of Firing Precision for Multiple Launch Rocket System
【摘要】 The research on multiple launch rocket system(MLRS)is now even more demanding in terms of reducing the time for dynamic calculations and improving the firing accuracy,keeping the cost as low as possible. This study employs multibody system transfer matrix method(MSTMM),to model MLRS. The use of this method provides effective and fast calculations of dynamic characteristics,initial disturbance and firing accuracy. Further,a new method of rapid extrapolation of ballistic trajectory of MLRS is proposed by using the position information of radar tests. That extrapolation point is then simulated and compared with the actual results,which demonstrates a good agreement. The closed-loop fire correction method is used to improve the firing accuracy of MLRS at low cost.
