---> NASA CHALLENGE 2020 <--- NASA RASSOR DRUM - 3 entries · 模型 267793
This is my entry for the NASA Challange. 3-scoops design with spiral structure of the drum internal space with intended fill ratio over 70% (over 35 liters). The spiral structure allows 2 aspects of main function: - to direct the collected regolith deep into the drum, reducing the resistance to collecting of new portions of regolith at entry area - to unload regolith due to reverse rotation at the unloading point evenly, which reduces the chance of regolith jam and sticking During transportation the drum stops. This reduces losses as regolith spillage is possible only from a small entry area of the spiral. Material of a drum is mostly carbon fiber because of a weight limit (calculation link: https://docs.google.com/spreadsheets/d/1ee9JULr8QjGDX7upZeuKtGVvxd2IF4I9Nd5RXKK6HgI/edit?usp=sharing), with antifriction alloys used for scoops. The 3D Model was created in Blender v. 2.79b + 2.81, the simulation of regolith grain excavation was created in Houdini v.18. Maximum total width of scoops engaged at any given time is less than 175 mm.
