DESCRIPTION: • This bucket drum is the combination of NASA’s RASSOR 1.0 and RASSOR 2.0.• The design is also ipired by the bucket wheel of the world’s largest excavator machine (The Bagger 288).• It is designed with keeping the weight, dimeional specs, fill capacity, fill rate, holding and unloading regolith efficiently, manufacturability and simplicity in mind. COTRUCTION:• Designed on: Solidworks• Rendered on: Solidworks Photoview 360• It coists of a bucket drum, although it’s separated in 4 parts in the render and the model, it can be made into a single piece or 4 pieces depending on the manufacturing process (recommend to 3D print the bucket drum in one piece for simplicity).MATERIALS USED:• Scoop blades: Titanium (Ti-6AI-4V)• Side blades: Titanium (Ti-6AI-4V)• Bucket drum: Carbon fiber• Side cap: Carbon fiberWORKING:• When the bucket rotates clockwise it scoops up regolith from the lunar surface and passes between the baffles into the drum chamber.• There will be no regolith dropout until it fills to its max capacity.• When the bucket rotates anti-clockwise the unloading begi.• The gradual reduction of the baffles in radius eures that larger stones don’t get into the main chamber and saves holding space.• This bucket is designed to have the least maintenance possible.• The side cap can be uncovered in case.• The side blades have grooves to have a grip on rocks while scaling tough terrain and it also helps in guiding and cutting through the ICATIO ACHIEVED:• Width of scoop: under 175 mm• Maximum bucket drum mass: 4.55 kg• Maximum bucket drum Diameter: 450 mm• Maximum bucket drum length: 360 mm• Max volume of regolith captured: max 37.18 - 40 lite• Fill ratio: close to 80%• Wall thickness (sub to change): 1.50 mmNote: The appearance and the logos in the rende is for visual representation only and the model is neither owned nor spoored by any company.I would like to thank GRABCAD for this opportunity; it has been a great learning experience accomplishing this challenge. THANK YOU ALL FOR VISITING! :)
