- Attach a longer wire to the reefing line which ties onto one of the loops (this should prevent cinching of the parachute when reefed)
- Do wind tunnel testing to make sure the loops can withstand force from reefing
Nov 17: Prototype 2 Ideas
Problem: Can’t reef the parachute as small as we were hoping
- Maintain one reefing line at the bottom, accept that the diameter will be bigger than we hoped
- Accept up to 5.5 ft drogue
- Multiple horizontal reefing lines, stacked up the parachute, potentially connected
- One reefing line, pleating the sides of the parachute before running the reefing line through
Problem: Pyro wires are unprotected and snapped during tow test
- Secure wires better: solder connections and use heat shrink tubing, run wire and some rope through the heat shrink
- Move rope up to where the line cutters are attached to reefing line
- Braided kevlar (bc that’s what we’re using for the parachute lines and it’s what we have in lab)
- Solder and heat shrink the line cutter wires to the ignition wires
- Use more wire, ensure there’s extra length
- 1.5x length we’re expecting
- 25.5 ft (1.5 times MPT riser)
Problem: Parachute was singed where the line cutter was
- Make a bag of the fire-retardant nylon fabric to cover the line cutter
