I'm building a gap staged Estes Photon Probe. The booster will be four inches long, so there'll be a gap between motors, and I plan on venting via holes drilled in the centering rings.
I know people have done this before, but I haven't found any guidelines on how much ventilation is appropriate. I was thinking four 1/8 inch holes, drilled through both centering rings.
Question is, is there a minimum amount of venting required? Does it depend on how large the gap is? And is there such a thing as too much ventilation, such that the sustainer motor can't effectively blow off the booster at ignition?
Thanks!
