12Dynamics of Multiple Launch Rocket Systems

12.1 Introduction

As a practical example in important engineering applications of the linear MSTMM, this chapter solves the difficult problem in launch dynamics of MLRSs using the MSTMM.

MLRSs with 40 launch tubes are the best equipped among MLRSs in the world today, for example the Russian БM‐21 type MLRS, shown in Figure 12.1. The number of launchers for an MLRS may be just a few or up to 40, and all the rockets can be launched in one volley in a few seconds, forming a glomerate assaulting strike. As a powerful oppressive weapon in modern war, MLRSs have received enormous attention from every powerful military country for their high speed, high power, violent firepower, long range, high mobility, ability to generate high‐density firepower in a short time, and many other tactical advantages. With the changing features of modern war and the development of new technologies, the status and function of MLRSs are more and more important. How can their firing precision be predicted? How can dynamic performance be guaranteed by dynamic design? How can rocket consumption in MLRS testing be decreased while still guaranteeing the quality of the test? To address these problems in the development, production and testing of MLRSs, it is necessary to solve the theory and technology issues that influence them. These issues have been given attention at home and abroad, for example the computation of vibration characteristics, the orthogonality ...
