Ammonium Perchlorate alternative

[Charles_McG]

The latest C&EN has a little article about a less polluting solid oxidizer than AP.

NABTNE (nitraminodiacetic acid bis 2,2,2-trinitroethyl ester) is said to have a similar density to AP, a high decomp temp, is insensitive to friction and impact and has the same specific impulse as AP. And it doesn't leave a smoke trail, apparently.

Anyone here heard anything else?

Yes, extremely expensive. And has no use in consumer/amateur rocketry.

 

[Charles_McG]

Odd hazards? Or just the expense?
Other than not being approved by our various governing bodies. I don’t think that would stop the amateur (not MR/HPR) side.

Gee.....
Fischer Scientific sells it for $1.28 per gram
A 2 grain H motor in tiger tail would be $181.96 just for the oxidizer.

Seems like a deal breaker.

 

[Charles_McG]

The C&EN article noted that some of the intermediate reagents are by no consideration ’green’ and it’s unlikely that it can be scaled up and made much cheaper.

Grab some ADN while you're shopping

There are no serious and practical alternatives to AP as an oxidizer at this time.

However, the Adranos invention of using a lithium-aluminum alloy to scavenge the HCL in the exhaust has promise, if the cost could ever be reduced to reasonable levels.
