Hi Guys

I have joined this forum in order to research slow burn propellants. I will most probably never darken your message board again after I have done this.

I am coming at this from a different angle to most of you since I am not amazingly interested in developing new and super efficient formulae. What I really want to do is develop, learn to produce, a small solid fuel rocket motor which is capable of powering small scale free flight and R/C model aircraft. These things are normally weighed in Grams and usually well under 250 Grams so I do not need high power and fast burn rates. Have a look"HERE" to see what I mean.


I need something with a long, 20 seconds upwards, burn and a thrust of between 50 and 200 Micro Newtons. It must be a simple mix and achievable without the necessity of having to replace my garden shed if it goes wrong.

The “normal” tool would be either a Jetex motor or a Rapier solid fuel rocket, both of which were developed to provide thrust in the minute quantities required for this kind of model but due to the increasing paranoia about terrorist action there are problems with postage of the Rapier and the Jetex has once again gone out of production.

So there you have the problem. Can anyone help?



Regards

Jim
