Update 5/4/2015 – The Gang’s Parade Gets Rained Upon

Hi all,

The gang has been hard at work over the past week to correct problems identified in the last pressure test. The LPRD team successfully fixed some data issues with the Arduino, including data shifts, time skips, and temperatures. In addition, the team received guidance from a mentor aiding the gang in fixing the valves, and, hopefully, eliminating the leakage. Over the past week, the team discussed regenerative cooling and the possibilities for improving the current engine. Also, Ansys simulations yielded some interesting and unexpected results, pictured below!

At the 5/3/2015 meeting, the sub-teams presented their progress from this past week to the group. The LPRD team learned a bit about fundraising, including how to use the “gift pyramid” and the concept of stewardship! The LPRD group will work over the summer to secure funding and needs to identify assets that would make it an appealing investment for possible contributors. The team also heard about some embarrassing, fun, explosive stories from team members!

After the meeting, the team attempted to do another round of pressure testing. However, the weather did not agree with this plan at all; the test was rained, or, rather, hailed out. Such is the struggle of living in Minnesota. The team still plans to run another pressure test in the coming weeks, and, although the team is taking a break for finals, the LPRD crew wishes to successfully hot-fire the engine by the end of the semester. Fingers crossed, and good luck with finals!
