I am giving serious consideration to making my own tracking smoke canisters in 29mm and 38mm sizes... just right to fit into a Pro38 or AT motor casing and then into a motor tube either set up as one tube of a cluster at the aft end... or into a tube built into the nosecone.
I need lots of thick smoke and I need it to last (at my discretion) anywhere from a minute to 4 minutes or so.
Ignition of smoke along with motor ignition at launch... smoke all the way up and all the way down.
Ignition of smoke in the nosecone tube set off by a breakwire when the nosecone is ejected (to avoid the obvious problems incurred when smoke goes off with the nosecone still attached).
I have visited the Firefox website and they have several formulas, some being already premixed and 'just add oxidizer' - others being a 'do it yourself' kit (non hazmat).
So here's the question - it would appear that there MANY variations on smoke generation formulas.... does anyone have any source materials for a non-chemist to make use of. Better yet, anyone have a tried and proven formula?
TIA
