Homemade orbital rocket?

Picture of Homemade orbital rocket?
I recently seen on tv, The U.S. government has stated that anyone who could prove they could reach and maintain orbit would be allowed, ofcorse that comes with many stipulations.
Here is my ideas and attempts at building one.
Admittedly this is a work in progress but progressing.

Here I will open my project to you the public to help me to perfect it,watch as I build and hopefully you will get to view the test trials and also the maiden voiage.

In the first few steps I will show my plans,materials and reveal my intenssions for this project.
I will leave this iable open ended untill the project is compleate the downside is you wont get to build just yet but after compleation of this project you should be able to atleast duplicate my work if not improve upon it.
So come on all you Rocket scientist and millionaire's I need your help.

Step 1: Step1

Picture of step1
I was browseing the web for some cool thing to call my next project I swooped by Mike Davis's web page where there is alot of cool stuff and was checking out his homebuilt jet engine and it reminded me of a drawing I had in my fileing cabinet from years ago when I was still in grade school. I dug a little and whiped it out and asked my girl friend if she want to see something cool, she replied yeah so I showed my drawing,she said what is that a new toilet invention.
I kinda giggled and said yeah. So after some hard thought planning I thought, "why not" and started to redraw my picture on windows paint, so I got my initial layout ready to post on i'ables, first here is picture of a model rocket I found online perhaps an ideal candidate for my fusilage design. ofcorse mine will have to be different,unique,personalized.

there is a huge difference betwee orbital altitude and orbit, anything this rudimentary barely has a chance of even making the altitude, let alone circularising an orbit. you need rcs or reaction wheels along with a gimbal nozzel and instead of phone gps you need a custom transmitter or computer, could be run on raspberry pi or arduino. you also need a gps module enabled at higher altitudes. they normally cut out well below upper atmosphere, let alone space. for fuel you need liquid oxygen and hydrogen, not impossible, but definitely a bit of work. staging is also a key factor
You can go to Google and download there free version of Google Sketch up 7 or buy it it is a fraction of the cost of a cad drawing system; the free will probably be all you need. This is a 3D drawing system and will help you design the rocket ship; hint ditch the pc paint drawing and use this it will make you look more professional. When I see something I like I will give you another hint, I don't build other persons aircraft but I may lend a hand.
Are you still trying to make that rocket? Because i'm trying to do the same thing with lox and kerosene.
ok srry to rain on your parade but im a college physicist and that rocket wouldnt even reach the upper atmosphere,giving the intensity of the wind at such great height even on a not so windy day. That rocket would need to be either at least 10 feet tall or it would have to be a very heavy, because the wind would blow it away. Since it would be heavy you would need better thrusters, if anything i would suggest c-42 v67 thrusters ,there about 2 feet long and 6 inches in diameter. They give good thrust and they maintain that thrust for about 2 mins. Now u would need to make an coco clock like device that would move a board after a certain amount of time to release the fuel. You could have so if lifts of the ground with one thruster, then you have 4 thrusters (one on each side) take it another certain distance,then 4 more take it the rest of the way. That should probably work. But i dont know y im getting your hopes up because once the rocket gets high enough the air pressure would lessen and that would let the rocket temperature drop and then ice would form and it would freeze the thrusters AND weigh down the rocket, so u need an internal heating system to kepp the rocket warm
of course, since it is LIQUID fuel, there should be a coolant for until it reaches that point.

you need to hit 17000 mph to reach orbit im told. ive just bought some hobby rocket kits that with the right rocket motors can reach a hight of  8400 ft. im in the process of building a harness so i can strap them to a 2300gram weather balloon. my intension is to launch them when the balloon pops, however ive not figured out how to trigger the launch the moment this happens. but such a balloon should reach at least 100000ft. at that height  the atmosphere is about 1% of  ground level. so less resistance more altitude? ten times more? hobby wireless do an outstanding tracker. plenty of mini digi cams on market, but they  need a 3 hour battery life. ive got some helmet action cams,cold a problem -50 or less. parachute ebay get military surplus drone and flare ones.  best i can figure hobby rockets reach 2000 mph on a ground level  launch, maybe wrong though. if i succeed ill post video on youtube. good luck.. dave uk.
a pressure sensor in the balloon should suffice for release. simply hook it up so it is triggered a few seconds before popping.

Honestly, dude, one, I think a cell phone would not work in space, two, I don't think that any home made rocket could reach mars, let alone a wormhole, which would be lightyears away. Also, I doubt aliens can read English.
most of this is correct. also, no sentient life lives on mars.

 If your phone was a satellite phone it might work, but if not it wouldn't get a signal in space.  You could try one of those tracking phones.  I like your enthusiasm and I really like the idea.  One I actually have a good fuel supply idea.  Normal rockets use hydrogen and oxygen so the provide fuel and stuff.  You could boost it to a good hight with solid boosters, then drop them when the air gets thin.  Then, using electrolysis create a hydrogen/oxygen rocket and you shouldn't have to separate them unless 5000psi would fuse them back together.

holy crap dude grade nine and u know all this i started to learn science and math like this in grade 6 but still not many ppl can do that like u and me lmao
your speech makes you sound like a three-year-old texting.
While solid state rockets are efficient up to about 1.5 miles of the atmosphere, anywhere above that it becomes not very efficient to use solid state. While solid state rockets work fairly well, they don't pack the same lasting punch that liquid state rockets do. Solid state rockets are more for ballistic rockets, traveling at an angle, toward a target on earth.

The solid state rockets can be compared to a shooting gun, with a lot of force packed into a short burst, while the liquid state fuels can be compared to jet engine on an airplane.

 I think a two-stage rocket would be your best bet. --Launch a bigger rocket with the smaller, primary rocket as the top half of it. then have a remote or some kind of timer to set off the primary when the bigger runs out of fuel. This process will get your primary up high enough to launch through the atmosphere with the most possible fuel conserved, and it will be more accurate than the balloon idea. Good Luck!
Drill a hole in the top of the uppermost solid rocket booster, then attach a fuse to ignite the next stage. that or maybe attach a filament to a very small Normally Closed relay. when the rocket gets to the end of its burn, it melts the filament, the relay closes the circuit and ignites the liquid stage or whatever.
most model rockets have what is called a "separation charge" which does two jobs: separating the boosters and ignition of the next stage.
why not try that in small scale?

considering the size of rocket it would take to reach orbit from sea level, take a look at high weather ballooning. you could easily construct a carbon fiber or cardboard launch tube that can be hauled up with 4 old weather balloons, and programmed to launch at a certain height or time limit. great idea by the way
this sounds like an idea I had some time ago, however the balloons were many feet apart. also, in the case of any launch similar to this, an autopilot would be needed for keeping it straight, but that should not be a problem.
Been done--about 45 years ago the US launched Project Farside 4-stage rockets from Eniwetok Atoll. Not orbital, but an altitude record at the time at 4,000 miles.

it wouldnt be stable so the rocket might not fire straight up and the wind would push the rocket away
I like the idea of using weather balloons. To simplify construction, you could use several large model rocket engines that fire in stages.
keyuboard cleaner wont work try liquid hydrogen
can u say illegal?
no?
how about death?

sorry to be a buzzkill
yes that exactly why i decided a while ago not to build a rocket.
feel free to make rockets, but dont go do something stupid like makeyour own motors. Those are a free trip to the ER.
kill joy
I admit, I was a bit anal about safety last year, which was before I actually made rocket engines. I then realized that they aren't that dangerous.
of course, hybrid motors ore very safe to make.
you're just molding rubber.
Its not illegal and i dont think he was gunna launch himself in the rocket.

Before anyone starts blasting this project I know its incomplete,got allot of wholes,needs work,add your comments and ideas help me make it better,finish it. keep in mind this is an expensive build and may take a year to finish.
You spelled holes wrong, just like all the other words in your instructable.
calm down!
jaronnix2 years ago
needs some work. Keep up the dreaming! i like that! but really? a bible? i already hate you christians spreading your religion, i doubt aliens would appreciate it.
ouch. that hurts.
Thank you for speaking on the behalf of anyone educated on this instructable.

Heres what i have learned after looking into building a liquid fueled engine. The biggest problem with fuel selection is the oxidizer. Gaseous and cryogenic oxidizer tanks are heavy and difficult to make. The most widely available liquid oxidizer is H2O2, which can be bought at 30% online and VERY CAREFULLY refined up to 85% though fractional separation and sparging. The big problem with hydrogen peroxide is that it requires very clean tanks and hard ware as it may DETONATE if it is exposed to even microscopic amounts of a catalyst material. However, this is also a good thing since it can be used to drive the turbo pump in a premix chamber as it acts as a monopropelent when exposed to a catalyst. For fuel kerosene works fine, a refined version with less dissolved waxes like napatha would be best.
Basic components: tanks, turbopump/ h2o2 premix chamber, injection nozzle, combustion chamber, combustion chamber cooling jacket (fuel or oxidizer pumped through on way to combustion chamber), exhaust nozzle, throttle valves, tank isolation valves.

Seems easy enough, however the flame temp in a rocket motor can reach over 6000 degrees with thousands of pounds PSI in the combustion chamber. Making an engine is easy, making an engine that doesn't explode after a 30 second burn is not.

Jeepers! You desperately need to get some books and do a LOT of study. I suggest Rocket propulsion elements by Sutton as a primer, plus a LOT of reading on the net. Richard Nakka's, site Jimmy Yawn, JP Aerospace etc etc. You can basically ignore most of the comments here as they are confused, inaccurate and misleading. Join your local rocket society and listen to their advice.
Some Info
Space is officially defined as 100km 62 miles up. An up and down by amateurs to this altitude has been done. See CSXT civilianspace.com
To leave earths your satellite has to achieve a velocity of greater than 11.2km/s
Look at escape velocity and orbital velocity on Wikipedia

I think it would be incredibly hard for your rocket to successfully make it into orbit. You need use H2O2 (standard professional rocket fuel) to get the most "bang" (H2O2 is illegal without a licence in large quantities, and the FBI will put you on their "watch list" when purchasing ANY amount of H2O2) Also, O2 wont be enough of an accelorant to get your rocket going. You need liquid O3 combined with h2o2 in a specific ratio.

Escape velocity is calculated by the formula:

ve = √2GM / r

where G is the universal gravitational constant, M the mass of the planet, star or other body, and r the distance from the centre of gravity.
In this equation atmospheric friction or air drag, is not taken into account.

Use this equation to make an estimate of how fast you need to get your puppy goin'. Also, you might want to consult a professional chemist, pyrotechnic, and/or physicist to make sure you don't blow your brains out.

NOTICE: You need to get a certain level of clearance in order to even launch a model solid state rocket with an engine over "E." I cannot even imagine the background checks, the questioning, the computer history searching they would have to do to you to give you the clearance needed.

Also, you would need an approved space to launch. The only place I can think of off the top of my head would be 3 miles off shore, in international waters.

Well, best of luck, and I hope my information helped you a bit. :)
H2O2 is Hydrogen Peroxide, which is not rocket fuel. There are some who use it for an oxidizer, but for the most part it is skipped due to the difficulty in handling it.

For simplicities sake, a solid or a hybrid propellant would work best. If you are to pursue a liquid, look into the hypergolics. They require more care in handling, but will prove far simpler for a first time rocket person. Fuming Nitric Acid with Turpentine, kerosene or Furfuryl Alchohol is an example of a hypergolic fuel option which is available to the home rocket engine person. The Nitric Acid is the expensive part, typically running $50+ per liter.

Another option which is easier to handle, but not as easy to operate, is Nitrous Oxide, like you'd get for race cars, mixed with a fuel such as Kerosene or Ethanol. Unlike the above fuels, this is not hypergolic, so it needs an ignition system which adds to the complexities of the design.
