Bi-directional Drum · 模型 267761
Submission Specifications: Diameter 449.9mm Max Engaged Scoop Width: 175 mm Volume: 1683.37cm^3 Material Selection: Aluminum 1060 Alloy Theoretical Fill Maximum: 32.98 Liters Fill Ratio: 75% Length: 360mm Mass: 4455.68 grams Description: Our design utilizes a unique bidirectional spiral to store regolith drum will be primarily made of Aluminum 1060 alloy which due to its high durability and low weight and thermal resistance. We took inspiration from the structure of snail shells and their helical nature. Regolith is shifted further into the center of the spiral with each rotation via the force of gravity and expelled when rotated in the opposite direction. The spiral structure functions as an internal support. Stress tests show minimal deformation on scoops and drum at forces of 1000 newtons. We chose not to implement a segmented assembly method due to the intrusive nature of regolith particle. Future Improvements/Modifications: This design was created with the assumption that manufacturing and assembly occurs on earth. Future designs can incorporate a more storage friendly design or different material choices.
