A quick video on how I use graphite nozzles in Aerotech Hardware. This is the setup I'm now using to characterize propellants in 54/852 AT cases. Obviously be smart and this isn't a full tutorial, and may not even be good advice. That's why it's experimental rocketry. Be safe!

I have used graphite nozzles in Aerotech motors for some time. There are Two things to consider. The graphite portion of the nozzle that extends past the closure tends to break very easily when the rocket lands. Also graphite doesn't insulate and conducts heat very well when compared to AT nozzles. I have learned that using a graphite nozzle in an AT case with anything more than a two grain motor, will cook your case. AT cases are thinner than snap ring EX cases.

Nice video. Were those your grains you made? If so that was a great burn. Also what was the formula and Impulse? This is Anthony btw...🤘

Those were some of my grains! It’s basically a tiger tail formula with 4% AL. Since no one seems to be flying this winter I’ve been doing a little mixing. Probably a J200 something. I need to get a better load cell than a bathroom scale and go pro haha. Not high performance at all but dead simple to make.

Great work! That was a really clean burn! Hopefully we can meet up somewhere this spring and drag those motors!

Flown a lot of graphite nozzles in Aerotech cases. Two things. One is that the nozzles that protrude beyond the case tend to break VERY easily when the rocket lands. Also phenolic nozzles transfer heat MUCH better and insulate LESS from the heat during flight than the Aerotech nozzles. I have found that anything more than a 3 grain WILL cook your case! Graphite nozzles are great in two grain motors. This has been my experience.
