Inert..show and tell motor

[tfish]

I made some "inert" grains for a show and tell motor. I replaced the AP with table salt. It came out pretty good. I did run out of table salt and had to use some sea salt which made then not so realistic.

Here's a good gif to use also...attached? Link?

Most excellent .gif, Tony!

Great display item! (did you get angry one day and decide to saw a motor case in half?)

I remember finding that gif when 1st learning about high power motors to compete in IREC. Did you create it (or know who did?)

Either you've got a little mistake, or (much more likely) I've got something to learn from this. On the tight side as pictured, i.e. the top of the motor, above the propellant grains, is what I take to be a delay grain. But there's no ejection charge or opening in the forward closure for ejection gas. Is it just for tracking smoke?

Also, nice job. Really nice.

That motor was a spent AT M 98mm motor. There are no 98mm or 75mm motors that use motor ejection.

I know there aren't, but wow, it didn't look that big. So is it a tracking smoke grain, or something else?

 

[Nytrunner]

It is tracking smoke

Tony, when is the last time you've used a motor eject motor?

Just look at the Aerotech directions......
