An Anti-aircraft Rockets High-low Emission System Design And Engineering Analysis

Along with the rapid development of world military technology, rocket weapon is endued with new mission namely that aerial defense. In view of the problem of low muzzle velocity and bad close grouping of shots. This thesis researches and designs high-low pressure launch principle launch system for rocket weapon, and then it adopts virtual prototype technology to carry out dynamic simulation.First of all, this thesis expounds the principle of high-low launch system, after .the establishment of collectivity design project of high-low system, it researches and designs all subsystem of rocket launch system, such as high-low charging design, nozzle design, launching guider design, this research work provides research platform for the latter chapter. Second, this thesis researches interior ballistic-trajectory and mouse out the rule between each design parameter and rocket muzzle velocity or recoil by numerical simulation. In this chapter preferable high-low pressure system design parameter is established. Third, it carries out dynamic simulation about high-low pressure system, including 3-D modeling, dynamics modeling, dynamics simulation, this part is the emphasis of this thesis. Finally, it researches close grouping of shots of high-low pressure rocket launch and finds out that the close grouping of shots of.high-low pressure rocket launch is better than conventional rocket weapon system.In summary, this thesis's work provides design foundation and theory gist for further researches about high-low pressure rocket launch system, and the research methods provides new thoughts and means for correlative research.
