Do It on EX day and we will treat it like a Shawn motor ( sorry Shawn couldn't
resist ) and put it at the away cell.

Yes, those are C-slot grains.

Suggest you think and consider for a while before selecting the
nozzle for something like this. Those AT 18m D loads have some seriously small
nozzle throats.
Tripling up the grains will triple the burn surface area. To keep the
Kn ratio in the realm of the realistic, a good starting place would be to also
triple the nozzle throat area. You have some geometry homework to do... 8^)
Even then... No guarantees. Might go boom. IIRC, those are C-slot
grains.

No clue to be honest. Brian was talking to me at DA about wishing he could
put all three grains from an aerotech 18mm 3pk of reloads in one case. So I
said I can do that. Last night I finally got around to it. The case holds all
three grains and a delay grain for possible tracking. The forward closure is
plugged on this one but could use the delay and charge. Will it work? Someone
else will definately know better than I.

Cool, that is a pretty long 18mm... what is the max impulse range?

Have Rob do some sugar loads for you for testing.

Brian, I finally got around to machining the 18mm hardware we talked
about back at DA. Not sure if it will work but I think it looks pretty cool. I
will bring a set to October Skies for you. The shiny object in the center is a
dime for scale.
