On March 15, 2022, Oregon’s first satellite was successfully deployed into low earth orbit. Engineered from the ground up by Portland State Aerospace Society, all designs are completely open source, with the intent of creating an affordable, modular CubeSat system. This way, if you are interested in scientific research on a CubeSat but don’t have the interest or resources to buy or engineer a structure, you can use OreSat’s structure. By going through the process of assembling, integrating, and testing OreSat, areas for improvement were made evident. The goal of the structure optimization UTEAP was to reduce costs, make assembly easier, and keep its ability to be machined on a typical university CNC machine. To approach these issues, the team consulted with the people who assembled the satellite. There were complaints with how delicate the current method was of securing the cards into frames. Several different configurations of parts were consolidated into one and some eliminated completely. There were fewer components to manufacture, and eliminating the start-up costs of each individual element led to a 35% reduction in cost to manufacture. The team came up with an assembly jig created to hold parts in place. Along with the reduction in unique parts, the structure is significantly easier to assemble. The new designs were verified with FEA to ensure they would not yield. They were also checked with CAM software, and they are still able to be machined on a student CNC machine. The team ordered the structure from a rapid prototyping service, and the parts passed physical fit checks. The OreSat structure optimization was a success, making the OreSat structure more accessible for groups wishing to do research with a CubeSat.
