NASA RASSOR Bucket Drum · 模型 267792
This design consists of 3 circular sections with 2 scoops in each section. In front of each scoop, there will be a set of spikes of an ascendant shape that will prevent objects bigger than a few cms to penetrate the scoops, while allowing the dust in. A spiral inside the drum will allow it to load regolith when rotating in one direction, release it when rotating in the other direction, and holding it when the drum is not rotating. The material used for the drum is carbon fiber, so the weight can be maintained under 5kg. The spikes and the sharp edges of the scoops and the perimeter will be made of steel, which will increase their resistance. The main advantage of this design is that no large objects will get into the drums. As we can see in the properties and technical drawing pictures uploaded, the design satisfies all the requirements: Width of scoops: 98 mm Bucket drum mass: 4,97 kg Bucket drum diameter: 400 mm Bucket drum length: 300 mm Approximate volume of regolith captured: 21,89 L Approximate fill ratio: 58% The volume of regolith captured and the fill ratio is based on the supposition that the approximate ratio that can hold regolith is the one shown in the right view of the technical drawing picture. I estimate that it can actually be higher, but I preferred to prove that it met the requirements even in a more pessimistic case scenario. I think this design would work and would not be complicated to fabricate, as the shapes and structures are kept simple.
