Are you referring to a Word attachment describing a depth that is 2-3 times the tube diameter?
In this case one might consider it "absurdly short"
The ejection charge can blow through the middle of the fluffy cellulose insulation.
That certainly makes sense, but I think because we where using a parachute protector it repressed that tendency. Interestingly there was still quite a bit of barf left in then tube. I was expecting it all to be blown out, particularly with the force of the ejection which was surprising. I was convinced just for a second that the ejection charge failed to push the cone out because the rocket was well on the way down, but when it finally (seemed like forever) did it was out in an instant.
My observation would suggest the the ejection charges on Composites are substantially more force full than BP motor. Anyone else conclude or know the same?
If one is worried about producing adequate pressure and volume in a large diameter airframe will dog barf help? Could it mean the difference in getting chute out of the tube? Can you use to much?
