Good for use at high-altitudes (20k ft+) b/c completely pressure sealed
Takes up approximately 5 inches in length of mpt

This is an article someone wrote about how they designed/built/tested a CO2 deployment mechanism using a solenoid
CO2 has lower pressure impulse than black powder
Need a mechanism to poke hole into CO2 canister
Spring-loaded system
Spring forces may be unpredictable at higher altitudes
Solenoid
Pyrotechnic Valves
Servo
Avionics potentially in nose cone depending on direction of gas canister
Need to figure out if one way is more effective for parachute deployment
Issues to test for:
Leaking of CO2
Premature puncturing
Failure to puncture
Tests should take into account low temperatures at higher altitudes, forces/vibrations during flight, etc.
