Gentle people:
I'm designing/building my first 6" diameter rocket and I have some doubts as to deployment tech.
It seems to me that at 6" the volumes within the airframe are becoming rather large for just igniting a deployment charge and blowing it up/apart.
Also, in >4" diameter I'm unsure about sealing the chute+shockcord assembly from the hot discharge of a deployment charge.
I know from experience that for 4" diameter rockets I can separate the sections, protect the chute assembly, and deploy the chute.
This leads me to thinking about a 3"/4" chute deployment cansiter/cannon within the 6" airframe.
Having not built a chute canister/cannon, the drawing is as I see it at this point.
I would like to hear opinions on the options/design..., and will appreciate any guidance on the subject.
