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
- Consider Payload in nose cone
- Do math on effects of bending stress, CG, and separation. See if it affects separation loads and charge effectiveness.
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
- 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)
