Identify AT Propellent by 'Serial#' on Grains??

I have a 4grain aerotech motor that I loaded last year & never flew (yes, the caps were loosened, and no ejection charge was ever added).

I HAD the paperwork rubberbanded to it, but that's gone missing, so I'm wondering if anyone here can tell me what propellant I have. The grains have labels that say: 00110801

I called AT, but they're gone for the weekend...so iffen anyone 'speaks' AT codes, I thought I'd toss you a challenge

If not, I guess I'll have to wait to call them next week.

Thanks!

that is a date and a lot code from that date.

day day , month month, year year, batch batch

don't hold you breath waiting for a call back

If you post a picture, I'm sure I, or someone else, could identify it by sight.

Agreed. I can recognize most of them, and I'm sure that many other people can as well.

00110801

What month has a day 00?

Aerotech has always been very good to me.

Scrape a couple grains off with an exacto knife. You don't need a large amount - a sixteenth-inch grain is probably enough.

Find a safe way to ignite it. Putting it on a piece of scrap metal and using an Estes launch controller is sufficient.

You should be able to get the color from even that tiny flame. Telling Vmax from Blue Thunder fight be a bit tricky, but ejection charge means it's not Vmax.

Vmax is made by CTI. You're thinking of Warp9.

Yep. Also, blue thunder is a pretty vivid blue when it burns outside a motor. It shouldn't be very difficult at all to tell from W9.

This is why I should not be allowed online the night after finishing a thesis paper...:blush:

The motor MUST have applied to something you had in the "que" at the time. Think back.

Stick it in a rocket and fly it. Once you do, you will know what color it is and since you know the case you will be able to extrapolate which reaload.

Other clues for identifying a motor:

• Delay length and color of the delay spacer. This data is published on the AT homepage.
• Nozzle diameter. A little harder to measure without the necessary equipment. Things with known diameter (drill bits, bolts, etc.) may be used to probe the hole. Wrapping paper around a suitable mandrel until it fits snuggly can be done too and allows for an easy measurement of the circumference. Nozzle diameters are documented in the AT assembly drawings.
• Grain core diameter. This is apparently only documented when a "non standard" core diameter is used, which is usually not the case (examples are the I-600R or the J-350W). Rough dimensions can be deduced from the assembly drawings.
• Grain length/Number of grains. This differs only in rare cases, like the I-1299N or the J-510W.
