Research on parachute manufacturers:
Deployment
Multistage recovery system
Think about the snatch load - reduce snatch load by keeping it in a deployment bag or shell
Should have two sections - a section for the canopy and a section for the lines - to reduce tangling
Individual lines stored in individual sleeves to prevent tangling
****want lines first deployment
Could put the lines in a bag and put the canopy inside a sleeve which is stored in a protective flap
Material - fire-resistant Nomex (to shield parachute from heat of expulsion charge)
Drogue shell?
parachute liner as replacement?(Fruity chutes sells them lol)
simplified parachute bag; good for CO2 deployment?
...
What we want to test:
Deployment and inflation behaviour of the parachute.
Stability of the parachute throughout the entire flight envelope.
Opening load of the parachute.
