Need a mechanism to poke hole into CO2 canister
Spring-loaded system
Spring forces may be unpredictable at higher altitudes
Vulnerable to vibrations during launch
Needed to by loaded during launch, so risk of early deployment
Solenoid
Arm attached to solenoid that moves to poke hole once
Pyrotechnic Valves
Still contains issues with black powder
Look into finding better way to seal
Reliable on ground, but questionable at high altitude
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.
