Rockets!

I have an old gunpowder rocket lying around in the garage, I am debating whether or not to dig it out. It is a fairly simple thing if I remember correctly, only 2 stages and the payload has a parachute for landing. I would like to know if anybody is interested in seeing a video / slideshow / instrucable on it? While I'm there I might find my old water rocket valve. And if I'm feeling really bored, I might make my own rocket and charges :-)

hobby rocket using rocket candy

Today I tested a homemade rocket engine made with r-candy and clay catlitter (for the nozzle and plug). The nozzle was made from clay catlitter with a tapered hole I used about twenty grams of r-candy then l put a thin plug of catlitter. I had placed the rocket upside down on a bamboo rod clamped to a table with a scale under the engine but when I ignited it the sound was so great that I had to step back and could not get a reading but from the looks and sound of it the small 500 gram scale would be maxed out then at the end of the 3-5 second burn the thin plug at the end popped off shooting the engine up in the air this was becouse the core was not drilled all the way to the end so when the burn was near an end it found it easier to escape threw  the thin plug then the narrow nozzle.

Water Rocket Launchers

Water rockets are fairly new to water warrior technology. To reduce our carbon footprint, water rockets are built using plastic bottles. This forum topic talks about the operation of standard water rockets and launchers, how they can be used in a water war, construction of water rocket launchers, rockets, and add-ons like water balloons on the tips of rockets, ammo clips, and grips as well.

How To Build A Rocket

A few years ago i came up with the idea of strapping a rocket to a merry-go-round. the little ones in playgrounds not the big ones with horses and stuff. i've been trying to find some sort of rocket hobby community since then but there are surprisingly little. and not a whole lot of instructables on rockets with enough power. so tips? hints on how to at least get started?

Water Rocket Launcher- High PSI twin rocket racers.

Ever wanted to know how to build a twin water rocket launcher? Have some expert advice on hand? Feel free to comment and help build a full metal, high PSI twin launcher. I am looking for assistance/advice you may wish to input. I was hoping to build a substantial base for launching multiple water rockets. It has a quad manifold so further expansion is possible. As you can see from the parts, it is very simple. I still need to add a isolating valve to stop water back flow into my pump (which will be located at the end cap, after the gate valve. The release mech has yet to be designed also. Australian gardena hose quick connects are the base for this rockets release system. I hope that is not too confusing. If it is, ask and I will clarify my babblings. Thanks for the assitance

The Ultimate Water-Powered Rocket!

NASA and the Air Force Office of Scientific Research (AFOSR) have launched a water-powered rocket 1300 feet into the atmosphere!The rocket was actually propelled by a frozen mixture of "nanoscale aluminium" (isn't that "dust"?) and water, pumped in at the consistency of toothpaste and then frozen in place. The propellant is known as ALICE (aluminium and ice - convenient, eh?)Earlier this month, the collaborative team, Drs. Steven F. Son and Tim Pourpoint of Purdue, Rich Yetter and Grant Risha of Penn State, Vigor Yang of Georgia Tech, Harold Bell and Frank Bauer of NASA, and Mitat Birkan and Thomas Russell of AFOSR watched as the rocket soared high into the sky, to 1300 feet near Purdue University.ALICE is generating excitement among the researchers because it has the potential to replace some liquid or solid propellants. It is a promising propellant energetically. Theoretically, when it is optimized, it could have a higher performance than a conventional propellant. In addition, because of the abundance and easy handling of the raw materials, ALICE could potentially become the propellant of choice for missions leaving other planets, since it could be (relatively) easy to manufacture from local raw materials and far easier to store than cryogenic fuels.

Water rocket plastic fusing

Hi, I'm a senior in a physics class.  We're currently building and launching water bottle rockets.  Our teacher told us of people that had tried to put two bottles together to increase the pressure they could build up, but said that they had failed because the pressure would leak from the point where they were joined.  Does anybody have ideas on how to make a water-tight double bottle rocket?  I had the idea to fuse the plastic together using heat, but I'm not sure how well this would work. This is my first post, so I'm hoping this is the right section to post in.  Thank you for any help and comments you could offer.

Cheap Two Stage rocket

If you were to take two model rocket motors and remove the secoundary charge (that pushes out the payload) from one and possibly fill the rest of the cartrage with homemade propellant. if you put one cartrage ontop the other and secured it with a little tape, would that work as a two stage rocket. does anyone think that the flame would travel into the secound cartrage and the pressure would blow out the first cartridge. Just wondering if anyone tried this before and is still alive and happy.

How to make (or where to buy) spring loaded fins for a model rocket? Answered

I think it would look really cool if I could launch model rockets from some sort of tube or underground silo. The only problem is that the fins get in the way of securely packing the rocket in the tube. I would like to know if there are plans for spring loaded fins or if there is a place where I could buy a set of spring loaded fins.

Need advice on making a proposed rocket I've devised different to the ones seen on here, before I waste materials?

I was thinking of making a rocket and using the fuses in a party popper as the propulsion, I was going to set up 4 gutted poppers with just the fuses on a 600ml/1 or 2 lt bottle and use a string fuse attached to the popper fuses at equal distrance running into a centre fuse/string to light it and get clear.I would use skewers or something to make it launch straight up.I would have the bottom of the popper housing/film cannister against the ground/launch pad. Has anyone tried this? Would the popper/poppers just simply blow up the thing I put them in and not work? Would I be better of doing the film cannister cannon thing instead of poppers.?

How can a rocket using liquid hydrogen and oxygen force a rocket upwards?

If hydrogen and oxygen are burned together they produce water.  You need a lot of hydrogen and oxygen to make a very small amount of water. If when burning those two gases together produces water, which takes up much less space, how can it possibly propel a rocket into space. You need expanding gases to force something forward. Hydrogen and oxygen when burned together IMPLODE they do not EXPLODE ! The two gases contract into a liquid they do not expand like conventional combustion of solid fuel !
