[BProckets] Cluster ejection

[Dan Durachko]

I imagine the engine loading procedure and mount design would preclude such
a measure but could you cross-match (w/quickmatch) all three of the ejection
charges to synchronize them and ensure ejection?  Also, I imagine there's
enough slop in powder amounts for efficient ejection that you could load
each of the three engines in the cluster with 1/2 the amount needed for
positive ejection and even if all three fired you still wouldn't cause any
damage?  Let me know how things work out and how you did it.


Good point, I guess the dilemma isuse one ejection charge and if that motor
dosnt ignite the fiberglass nosecone turns into a pretty dangerous
projectile. But if I use 3 unsyncronised ejection charges the result could
burn up the chute(s).
