Would it be feasible from a regulatory or cost standpoint for Loki?
Well what can I say. My customers pay attention.
Most of my answers have been given above, thanks guys, but given again below in order of importance as I see it.
Case spacers are-
- another point of failure if hardware internals are not kept very clean deep down inside the case,
- another part to machine and inventory for each diameter This adds more inventory cost for little return because case spacers would be
- maxed out with the current hardware being 2 grain sizes apart as they are. That and they are still
- going to require the purchase of another single nozzle size. For a little more you have an entire motor case.
-also heavy and reduce ultimate flight performance if you are over optimal mass.
Thanks for the inquiry just the same. Personally, this company isn't capable of producing ever conceivable case size, nor would I every really want to unless there is a huge hole somewhere. How big is a big hole? That depends on who you talk to. To me, unless it's a 54/4000 and the grains are 10.5" long, adding one singe grain to a motor case doesn't do a whole lot to get me excited about a "bigger" motor. That's just me though and I know customer wants/needs are important, but some things are easier to accommodate than others.
The 76mm current 76mm bulkhead protrudes from the from any 76mm Loki case by a distance of 1 & 9/16" (1.5625)
This includes the head bolt.
The front of the thrust ring is located .760" from the end of the case and the 76/8000 case is 40.875" long.
So from the top of the head bolt to the front of the thrust ring on the 76/8000, the distance is 41.678. Round it up and make it 41 & 11/16"
