Hi
I am fairly new to rocketry and have tried making some rockets in the past but have not had much luck. The only real method I have ever tried was dissolving Sodium Chlorate in water, pouring it over some kitchen paper and letting it dry. I then would compact it in a cardboard tube and seal the end but leave a small hole. When lit, these would go 10-15 feet in the air. I am interested in expanding my knowlege in rocketry and was wondering if anybody knew any sites or links that would tell me more. I know about the theory side of it e.g a fuel and oxidiser are mixed and compacted. When lit, they produce a lot of gas and if there is only a small escape, it will push the object forwared ect.

Thanks

Hi

Thanks for the info. In the message I was going to ask where aluminum powder could be bought from because I heard that it was good for use in rockets which sounds about right because it is fairly reactive.

Thanks

You definately want to check out Richard Nakka's website if your interested in rocket motors. Very interesting reading.
Click here

I think I might move this thread into the rocketry forum, will leave it here for a little while.

Thanks for all the information, this sounds like a nice freindly forum and you should be hearing more from me. As a little favour in return go to http://www.gardenchemicals.co.uk/ to buy some interesting chemicals. I have not bought from there, know what the chemicals are like or whether anybody would be interested in them but still, have a look anyway

I could only find four chemicals on there and they are out of KNO3 and its a rip off. I get mine from a farmer for free.
Try coming out into the country, the air is fine.

Yes that site is a rip off. Garden Direct or a farmer are best bet for KNO3.

Only posting this reply so I can get a star.

Is that cheating?

I was referring to gardenchemicals - (in the hyperlink a few posts above), not garden direct - but then i think we have worked this one to death.

Honestly though, do chat up a farmer or two, out here in the country KNO3 comes in tonne sacks, craned off the back of a lorry.

P.S.

Before you all jump on me i'm exagerating, mine came from someone with a couple of 25kg tubs:rolleyes:

but it was free.

Can't find Garden Direct - are they web based?
