Rocket Propellent

Unread postAuthor: cannon freak » Thu Aug 17, 2006 12:40 pm

I have been looking around for quite a while to find potassium nitrate for some simple home made rocket motors, however all I have been able to find was ammonium nitrate. Can ammonium nitrate be used in place of potassium nitrate?

Or does anyone know of another rocket propellant recipe involving ammonium nitrate? It can not involve really expensive and hard to get chemicals because I don't have the money.

Thanks.

I don't believe this is against the forum rules since I have no intention of using it with a potato cannon. If I'm wrong just delete it.

Does any one know if it is legal or not to construct your own homemade rocket motors in Canada?

In the US I know that it is illegal to pack you own rocket engines with out a special permet thing. Try the NAR website

...you might try mixing fine, dry NH4*NO3 with fine charcol powder, 80:20. I don't know if it'll work for rockets, but they used to use it for propellent in naval guns.

Well I have always known this but if your in canada this is gonna suck for u. Here's the link http://www.skylighter.com/mall/chemicals.asp?Sort=P#CH5300. The catch only to be shipped in the USA. I was talking to a long time friend and he always finds chemicals that cant be sold by making them. Find out how to make potassium nitrate if you cant buy it.
OH yeah no ammonium nitrate wont work.

Common formulas for pyrotechnics(all measurments are by weight):

Solid rocet fuel (old'en days)
sulfur (powder) 25%
zinc (powder) 75%
(caution!!!: very suseptible to ignition via: shaking or static)

I heard that mixing ammonium nitrate with aluminum powder and then casting them together with a binding agent works fairly well, is this true?

If it is any formulas?

Well if solid fueled rocket motors are illegal perhaps a hybrid motor then.

I know that liquid N2O and paraffin wax are a good, but can the N2O be substituted by another liquid oxidizer?

A hybrid motor will probably be legal wouldn't it since the fuel and oxydizer are not combined until the point of ignition?

You didn't get it... all artisanal rockets are completly prohibited in Canada if you don't own a license.

Artisanal is an home made rocket... So, basically, any rocket made by someone who is an amateur, who does not have a license or expertise in rocketting is absolutly Illegal.
