This report provides an insight into the mallaunch associated with multiple firings of free flight rockets from a mobile platform. The effects of resonance with the structure and firing rate are presented. As the mass of the load decreases (as rockets are fired), the launcher's structural frequency changes and passes through this resonant condition. An analog simulation program developed to demonstrate this resonant condition, is included in Appendix A. This program, has been developed and is presented as a tool for future use. It will be useful in developing a General Support Rocket System. Curves presented show typical mallaunch values due to thrust misalignment and malaim magnitudes associated with multiple firings.
