2027 IREC Changes

#6 shear pins, at least 4 (maybe 6?)
- Do the actual math on drag separation forces and force generated, instead of just using what has worked in the past
- Tighter shear pin holes with thread engagement.
- Intentional thread engagement, not in all tubes
- White shear pins
- Testing at various preload?
Research vent holes in recovery tubes
- What size, how many, do the math on what effect it has and how much we need it.
Test Single separation, dual deploy system with tender descenders
- We need to figure out a lines diagram and do lots and lots of subscale testing for this, Cooper is willing to fly L3 at SOD in September/October (Sasha L3 ASAP)
- Demonstrate repeatable successful deployment and recovery with flight testing.
Chute bag VS SRAD Nomex
- Can also run an SRAD chute bag, but we should fly a cots one a couple times first
- Reasoning for chute bag is predictability in maximum outer diameter, your main chute can't get stuck as it is physically constrained. It takes a lot of the guess work out of the fold
SRAD ballistic drogue
SRAD nose cone
- Conical VS VK
- Laid up VS filament wound
Payload in nose cone
Motor assembled way before we go to IREC, need copies of closures and casing (last years?)
Test RC2 and RC3+ flight computers with charge authority.
- Maybe, keep in mind we didn't have a single failure due to flight computers this year
Better setup of recovery wiring
- Avoid pinch points
- Going to need a complete revision for single sep dual deploy, need to figure out where we are going to seperate (nosecone vs airbrake)
Thread retaining bolts and shear pins into bulkheads
Make team leads read their portion of the DTEG
