RASSOR Bucket Drum · 模型 267804
The submitted bucket drum design utilizes curved internal baffles that allow for efficient loading, hauling and dumping. The assembly is lightweight, simple to manufacture, and can be easily adjusted or scaled to support a wide range of missions and conditions. During loading, the ten offset scoops allow for low engagement width values at all times. The regolith enters the drum through non-concentric baffles which allow for an increasing opening size and a more efficient loading process. The smaller baffle set is positioned such that regolith will flow from one enclosed side to another while the drum rotates in the loading direction. During hauling, the pathways are very limited for regolith to be released once the bucket drum is not in motion, regardless of orientation. During dumping, the regolith is free to slide out through the baffles while the drum rotates in the unloading direction. Depending on mission conditions, the efficiency of this cycle may be increase by utilizing a lower RPM or indexing the bucket drum assembly, if possible. While I do not currently have access to simulation software, I am confident that the design meets all requirements and will perform efficiently due to its unique internal baffle design. The available space within the assembly is approximately 90% and this design is expected to achieve a fill ratio of 75% or greater, once tested. Thank you for your consideration.
