Im starting a degree in mechanical/aeronautical engineering this summer. It might be nice to kinda work on plans for this in my free time, hell the spitfire was basically designed in a shed ands its what we british do well. If the british can take pictures from the surface of Titan then sure as hell can i help to stick a mobile phone into orbit.

Basically I realized that a payload system for launching things into orbit is generally either a two stage or three stage rocket. The only problem is that when you do this stuff in your backyard you've got two problems; 1) Recovery isnt easy and you sure as hell want to recover something that expensive, 2) Theres a shit load of research you have to do into the laws of wherever you're launching from. If your thing hits a plane your screwed.

Well the fuel that you would use would have to be assessed from a weight saving perspective if we are to do this on the cheap. Liquid fuelled is off the list as it weighs far to much, the only reason it is used is so that the engines can be controlled, once a solid booster is lit that's it.
Probably a solid fuel with a liquid oxidiser would be a good bet, you could then control the ferocity of the burn for the first stage using a mix of say a hydrocarbon (like rubber or paraffin) with a liquid nitrous oxide. (i know it sounds obvious but its the simplest idea with the fewest drawbacks from my chair)
(if you eventually go to space)In terms of recovery a simple GPS unit housed in each stage would be the best system allowing easy tracking recovery. The orbiter could be calculated to orbit the earth a few times then renter, the design could be made to auto rotate itself so that say a ceramic heat shield would protect whatever we wanted to send up.
However, This is all based of pre university knowledge, but the basis for it is relatively simple in theory. Oh yeah, we would also have to take into account vertical oscillation (pogo resonance) The early Russian rockets shook themselves to pieces and the Saturn V experienced engine shutdown a few times due to it. Model rockets that are larger than 10 ft long also will experience this due to the flex in the build material.
And yes i know that space is to far off but a low orbit might not be to far fetched. Probably is, i just want to make something go as high as possible and recover it to be honest. Probably an idea for my mid life crisis.
If we hit a plane I'm moving to Mexico and setting up a drug business.
The support list is*[B]glowing[/B] with donators.
I've allways wanted to see a star explode :(
Still they are slow like 100 billion miles in 1 second but I would really like to see one.
make it happen, just do it
Good news everybody, the engine construction is almost finished.
I have to use epoxy on some parts and then buy fuel and I should be set. Once again I'll state that I hope to have it finished by the 30th, and probably a video up sometime after that.
How are you planning to recover it after launch?
Some sort of parachute and if I can get my hands on one some sort of beacon locator thingy, have to do more research into that.

Go watch Kids Next Door then come back
Guys, its hard enough getting a rocket into space using Kerbal Space Program
I prefer the weather balloon idea
Good news! The fuel I made has a nice burn, got about 2 seconds with less then a gram of it, which is amazing. Next test is gonna be about 1 gallon of the stuff. Lots of smoke.

Also, what do you guys think about starting up a Kickstarter project for this?
[QUOTE=alphatwo;28060642]Screw copying the goons, we need to make a submarine.[/QUOTE]
Yes, I say we make a one-man submarine and see how far down Jaanus can go under the ocean before he loses all oxygen or gets his ship crushed by the pressure.
How long do you guys think this this will take to actually take flight?
To get to space? A long time. To go pretty high? A few months.
[QUOTE=RidingKeys;31864868]To get to space? A long time. To go pretty high? A few months.[/QUOTE]
I can save time, lets just get pretty high.
Unfortunatley, I don't think I'll be able to cover the full expense of the fuel. It's about $200 for 3 gallons, and I just don't have that kind of money to spend. Next time I do my test i'll be filming it though, hopefully it may convince some people to donate.

Kickstarter is a brilliant idea, by the way!

Go borrow a helicopter and land on the moon,good luck we're counting on you.

I don't understand why people don't do this. I mean helicopters have a button to go up just hold the button down until you're in space!!
I need to buy a really large pot, I can't find one in any store though.
Forecast shows that Hurricane Irene may hit Florida, which sort of dampens my plans for doing another test this week.
I've always wanted to have a Nerf battle in zero-gravity. It'd be some Matrix shit.
[QUOTE=LuaChobo;31932410]It would either not work at all...
Or cause total destruction everywhere.[/QUOTE]
Oh, God. Imagine the Minigun. No mobility issues, noise, low chance of jamming without momentum...
It'd be a gamebreaker.
Hi, I'm now continuing to ask for donations. I'd really appreciate any money that can go towards manufacturing fuel. Thanks.

There is a small problem with a minigun in space, a little thing called recoil. They make quite a lot.
It's not a good idea to go throwing yourself about in random directions in space.

Talkin' 'bout Nerf here. Rarely much recoil from a system that doesn't use anything other than air and electricity.
Edit:
[QUOTE=LuaChobo;31943591]Uh, if you have oxygen (In other words if you can be alive) sound can occur with vibrations.
Unless you mean actually being in space with an oxygen tank.

I meant that, yeah.
