The work aims to improve the professional ability and technical support capability of the accompanying ammunition during the operation of the weather modification mobile rocket sled in such aspects as the packaging, transportation, storage and safety protection. Through the visit at the grass-root level, literature search and prototype design, the storage and transportation characteristics, environmental factors and the development and current situation of inflammable and explosive articles regarding the packaging, storage and transportation during the operation of weather modification mobile rocket sled were analyzed. The practical application indicated that, the ammunition storage and transportation case of the weather modification rocket sled could carry fifteen WR-98, HJD-82, RYI-6300 and BL-1 weather modification rocket projectiles, which could meet the actual requirements of the current rocket sled and greatly improved the safety performance and operation effect of the multi-missile rocket launcher. The hidden dangers during the ammunition storage, transportation, safety and other aspects of the weather modification rocket sled are effectively eliminated, which improves the operation efficiency and ammunition management capability.
