Abstract
The engineering problem for this project was related to designing a payload to take photographs of the sun, while being subject to higher altitudes, and low temperatures, as well as any instabilities. The goal was to make a reliable, stable device in these conditions. This device was to be used during the 2024 eclipse in Texas as part of the Nationwide Eclipse Ballooning Project.
First, once the early sketches were developed, analysis was performed for different components and systems where dimensions or other specifications were calculated. Dynamics, materials, statics, and fluids were all considered in the design. Next, the manufacturing plan was created and executed, mostly involving 3d printing and laser cutting, modifications were made along the way to adapt to any errors. Finally, through testing, the device was evaluated in its abilities. Various tools and processes would be used in these three steps to ensure a working device.
Test showed that the payload could survive cold temperatures with minimal deviation on the equipment readings, of near .5%, below the requirement, and could last about eight hours on battery power, more than the entire required six hours. Also, due to the parachute selection and the ring profile, its fall speed was less than the required 50 ft/sec at about 40 ft/sec, allowing relatively soft landings.
