Ultra-short-range Air Defense System Launch Device Analyzes

The thesis took the compressed air launcher as the research objective under the background of ultra-close range defence of important target, aimed at designing a compressed air launcher to against the terminal sensitive bullet. Used the combination of fluid-structure coupling theory, principle of electromagnetism and mode analysis theory to accomplish the ballistic design, structure design and the mode responding analysis.According to the combat characteristic of terminal sensitive bullet, the thesis ascertain the inner ballistic requirement of the launcher. Established the analysis and design model of inner ballistic in AUTODYN software, ascertain the length of the launcher and the diameter of the circulation channel of the compressed air. On the basis of the structure parameter gained during the ballistic simulation, designed the launch control device under the condition of highly fast reaction requirement and none initiating explosive device, established the solid model in three dimension model software. Lastly, did the mode analysis of the launch tube to check if the launch tube could be influenced by the automobile platform because of the vibration characteristic.Through the analysis and design above, the principle and tactical feasibility of the compressed air launcher were proved, the work accomplished in the thesis was of reference for compressed air launcher and ultra-close range defence.
