Got a question for ya'll...
I like the idea of using a containment tube to confine the blast of plack powder, but I'm confused as to whether or not the tube is closed or open on the end opposite the charge. If it is open it will protect the chute and lines from being burned, and the entire parachute bay will be pressurized. If it is closed, everything will be protected as well and the charge will pressurize a much smaller area. Do people use both methods or is one preferred?
I am building a large rocket (11.5" body tube) and it seems to me that if the containment tube is closed and is located on one side of the parachute compartment the force might cause the two sections to jam at an angle and not separate cleanly. If I use two charges opposite each other I can hope, but not be guaranteed, that they both ignite at the same time. So, maybe the entire compartment should be pressurized?
Ok, enough rambling. Any thoughts or wisdom would be appreciated.
Thanks,
Leland
