grain length and core size

[lmt56]

I would like to put together info on grain lenght and core dia. for AT, AMW, Loki & Gorilla motors. 38mm up to 98mm.
Any one have a spread sheet all ready made up?

Aerotech grain length is on thier drawings in the resource center.

Loki website has total propellant lenght, and suggested bates geometry.

i have never measeured the cores on loki or aerotech.

This data can vary. For example, not every AT 38mm motor has the same grain length or core diameter. Sometimes there are even different geometries in the same motor.
This list would be either very long, with lots of special cases, or not complete.

With all due respect, the size of the data field should never be a disincentive for creating or using the data. Incomplete data is an indication of failure to exercise due dilligence, with exception for the obvious time and resource constraints. I for one would be very interested in exactly this type of information as it would help to understand more completely the burn charachteristics through direct observation of motor performance against the propellant grain geometry data.
