SRR Key Takeaways

https://cloud.wikis.utexas.edu/wiki/x/LwdtD

Overall

  • we need to define how we are going to do reference points on the mold, and confirm that the knowledge is transferred

Aerodynamics

  • We need to solidify the plan for splitting up work and creating different parts of the shell(nose, tail, how to we avoid it messing up the overall geometrey)

  • Talk about roll cage in an intersystem meeting, because thats the next big thing that defines what we do

Composites

  • Figure out design of windshield with respect to the polycarb and what materials we should use

  • LOTS of wesley notes, not worth putting all in this spot since its lot of smaller specific notes

  • resin infusion is a risk and will cost a lot of money (vacuum)

  • consider having aeroshell PDR at the same time as dynamics and frame CDR

Weekly Updates

  • Need to do more daybreak work

  • Might need to redo/rethink some of the cooling solution due to new regs

  • Adjust module mounting and bus bar location since we are removing load from midpanel

Daybreak Progress

  • Extending daybreak controls arms by 2

  • BPS and Contactor layout complete

  • Main enclosure complete, need to add mounting locks and roller wheel

  • Dashboard layout and connections finalized - controls has v1 done, waiting for review and order

  • Opened up battery and identified broken modules. Prat and Frank will have ppl go up and start fixing it to start motor testing.
