I am working on the design of a dual deploy recovery system for the Madcow Cowabunga Mammoth that I plan to purchase soon. I'm planning to put a 6" diameter chute cannon mounted in the middle of the airframe tube. Apogee ejection charges will separate the nose cone and release the drogue. The main ejection charges will blow the main chute out of the chute cannon tube. The chute cannon tube will have a cap, held on by shear pins, to prevent the main chute from coming out prematurely. The chute cannon tube will be removable, bolted to a centering ring in the 11.25" diameter airframe. The av-bay will be bolted to the aft end of the chute cannon tube. The main chute ejection charge canisters will be located on the top of the av-bay, firing up into the chute cannon. My question is about the location of the apogee charge canisters. The only place I can locate them will be on the centering ring that the chute cannon is mounted to. This ring will only be about 2" wide, so the apogee charges would be close to the wall of the 11.25" airframe tube.
So is there any problem with locating the ejection charge canisters close to the wall of the 11.25" airframe tube? Or is there some reason that the charge canisters need to be near the center of the airframe tube? Is it correct to assume that if the only purpose of the charge canisters is to pressurize the compartment, then it should make no difference where the canisters are located?
