Piston
Used on Phoenix, Staging Demo and HADES
Piston failure experienced on Staging Demo II (resulted in sustainer destruction)
Pressure sealed so can be used at high-altitudes
Although risk of no pressure seal on the firebolts (mitigated using hydrostatic testing)
Overall black powder is less reliable at higher altitudes (lower pressure slows down combustion propagation)
Takes up 8 inches in length of mpt
Can be reused
Look into & test shorter pistons?
CO2 Canisters
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
