I have a small EXCEL spreadsheet that somebody might find useful that I will gladly share with you. When I took over TMT in late 2016 I had only a vague familiarity with commercial motors, because I have been almost exclusively an EX guy for about 20 years. So, to make it easier for me to get instant access to the core data relevant to any particular motor, not just Aerotech, I began compiling this mini-data-base. It is constructed mainly from three different data sources: The Comprehensive CAR/NAR/TRA Rocket Motor Certification List, published in "Sport Rocketry" every year and found on the NAR website [columns B through H], the online catalogues maintained by the manufacturers themselves [columns J through O], and
www.thrustcurve.org [columns Q through X]. Column P is something that you are probably not interested in, but which might concern me a lot in the future, so just ignore that. If the motor is listed in either Thrustcurve or the manufacturers catalogue, but not in the "Combined" list, the data appears under the combined list in yellow text (I needed text in that column so that I could do some sorting functions, but I didn't want to imply that the motor is certified for use).
As you can see, almost all perms and comms of which list a motor appears in can be seen in this spreadsheet. Life is full of uncertainty and unknowns, we must learn to live with it.
I make no claims for perfection here, this was just a quick assembly of published data that I put together so that when somebody mentioned, for example, a J535, I didn't need to stay completely ignorant for long. If someone wants to proofread me and offer corrections, they will have my gratitude. Enjoy!

p.s. one more thing, if you sort on column A, all the manufacturers get mixed up, but the list sorts in a smallest to largest order. I'm leaving town this weekend to attend the big Labor Day Launch in Camden, SC, so I will not crank up the computer again until maybe Tuesday. Y'all have a good time at LDRS!!
