To kick off spring, the team held a trade study on engine propellant choice and ultimately chose to use liquid oxygen and ethane. The team also began doing some research into designing a new test stand. They are looking into designing it to be on a trailer, which will make transportation very easy and allow for flexibility with test sites.
Over the summer, the team did a lot of work on the design of the new Prometheus engine design, which will be targeting a thrust of 150 lbs. They also did a lot of development on the test stand trailer that will used for the static fires of the engine.
Towards the end of summer, the team began focusing on onboarding new members once school started in fall. To facilitate this, the team found tasks that would gently introduce new members to the project. This allowed the team to integrate new and inexperienced students while, at the same time, making sure that they would not be overwhelmed with their work.
As the fall semester begins, the team has been hard at work onboarding new members. The team has set a PDR date of November 17, where they will present the redesigned engine, test stand, and many more to a panel of other SHC members and industry professionals.
A Work Breakdown Structure was created by management to further organize the team and give them a set deadline of tasks that need to be accomplished before PDR. The team also ran an integration test confirming that their pressure transducers gathered pressure data accurately. At this time, the team also had three posters created to present at the Von Braun Symposium.
Finishing up the semester, the team decided to switch the material of the engine from stainless steel to copper. Although copper is harder to machine, it provides better thermal conductivity, which is more ideal for the team's needs.
