val77 Posted July 29, 2012 Posted July 29, 2012 hello allI have a question about a concern that opposes me so I want to do a parachute flare but I do not know what to composition in the Bengal light ...I thinkKNO3 59% sulfur 30% and 11% meal powderor75% and 25% KNO3 magnalium What do you think? you have a better solution?
Seymour Posted July 29, 2012 Posted July 29, 2012 The second will be much brighter than the first. To get a brighter flame still (if you desire it) you can add a lot more MgAl, since the excess burns in the air. Some organic fuel is usually added to regulate the burn, hold the mix together, and generally make it less like flash. You might like something like... KNO3 45MgAl 45Red Gum 5Dextrin 5 I chose Red Gum and Dextrin because they are bog standard. Dextrin is the usual binder as well as being a fuel. I wanted more fuel, and Red Gum is the usual choice for this purpose. Ideally I would use Gum Arabic instead of Dextrin, Resinox instead of Red Gum, and Barium nitrate instead of Potassium nitrate (Barium without halogen emits more while light than Potassium), but you have to work with what ya got. If you don't have Red Gum or Resinox, something else will work.
val77 Posted July 29, 2012 Author Posted July 29, 2012 woaw thank you for the quick response!I thank you notes you have
val77 Posted August 12, 2012 Author Posted August 12, 2012 I find a formula but I have doubts45 Barium nitrate / mgal 45/5 red gum / 5 dextrin composition is good?
Neruda Posted August 29, 2012 Posted August 29, 2012 composition is good?Seymour already answered this question:Ideally I would use ... Barium nitrate instead of Potassium nitrate (Barium without halogen emits more while light than Potassium
