Was there an AT G45? Did you mean G55? https://www.thrustcurve.org/motors/AeroTech/G55/

Or maybe the old G42?

No thrust curve but it looks like AT had a G45, see pg 3:

I checked my records and can't find the data. Just a reference to it in one of our nozzle drawings.

I always forget how long Aerotech has been around. (Sorry, Gary, I'm old too )

The first crawl of the Aerotech website I could find was from January 1998, when the SU motor lineup (at least the ones listed) was much like it is today but with many fewer offerings: https://web.archive.org/web/1998011...rocketry.com/products/motors/SUmotorlist.html

There was a lot going on before then that I guess only survives on paper and the odd random scan.

Maybe in an old copy of wRasp?

Good suggestion, but the oldest one I could find, from 1997, doesn't have the G45.

I think mine is '95-96, but that PC isn't exchanging pleasantries right now to check.

I found a later 1992 catalog from AAA at https://plans.rocketshoppe.com/pubs/AAA/AAA-1992.pdf that lists the G45 as a 29mm motor with 120 N-s total impulse and a burn time of 2.7s, but still no thrust curve.
