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.

hey if a bunch of kerbals can do it, why can't we?

If I were you I'd go with liquid rocket fuel would have to be LOX and concentrated H2O2 which you can always concentrate by boiling 3% to evaporate the other 96% water and 1% additives or buy bleaching agent. Anything over 53% hydrogen peroxide is considered a VSO (very strong oxidizer) and you'd need to have a Chem license to own a stronger concentrate. Cell phone? Nope go with sattilite telemetry, like an iridium sat phone. The mixture of these two oxidizers will have to be kept cool with a nitrogen sleeve or else kaboom. Your terminal velocity would equal out to 2KG per every lbs that's the rule of thumb for NASA. Depending on your weight you'd have to situate your CG so your rocket will reach a successful TV and not tip or lean which would induce drag you'd want it going as straight as possible because at higher velocities under newtons law one very very small degree off would cause your rocket to slow and prevent you from going into orbit. I believe the hardest part will be to punch through will be the ozone layer because it is so dense [to block solar radiation] then of course you'd have to take gravitational pull from earth into consideration and figure the optimal point you'd need to have your rocket travel in order to escape the gravitational pull. Then of course the fuel consumption it took you if you even attained F (floating point) you'd have to think well hmm now how far can I go. Oh don't forget to take into consideration extreme heat and cold temps for your electronics as well as solar interference, not to mention all the interferance you'd have to succumb to.... Literally by the time you actually build this it's going to cost you enough that you could have gone down to space X and paid for a flight to the moon xD just being a realist here bro...
2kg per every ounce srry I use my phone and it types on autocorrect lol

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.

.....That could actually work. The weather balloon thing. Using it as a launching platform. And as for the sensing the balloons pop, you could always time the pop. I mean puncture the balloon yourself with some puncture mechanism so as to make the process more streamlined. But great idea, I know ill be thinking about that.

a pressure sensor in the balloon should suffice for release. simply hook it up so it is triggered a few seconds before popping.
To all of you people saying that satellite phones would not work, you are wrong. there are satellites that are much further away.

Hate to break it to you but the smallest rocket that could reach orbit would be around 30 feet tall, this is not because of gravity but because of the dense atmosphere we live in and if you do the maths behind how rockets work that's the basic minimum. If you look on the bright side a 30 ft rocket is achievable. I am 15 years old from Australia trying to complete the same task as you and so far my best rocket has reached an altitude of 70,000 ft and that rocket was 10 ft high. Also think about building a 2 stage hybrid rocket they are really easy for amateur rocketry and cost effective, But by all means keep dreaming if you push yourself and learn the maths behind rocketry and stick with it you could get there one day.


Dear Aidan, I am a rocketeer like you and I would like some help to build my own. So far I have been building sugar rockets that have been getting over 2,500 feet high. Do you use liquid oxogyen and liquid hydrogyen? Respond at my email: I wish to speak with you soon.

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

GPS would not work outside of the position of a geostationary satellite.

sorry that was proven incorrect a while back, GPS in space works, both below the orbits and above the orbits. Wierd, but it was tested. the problem is that there might not be enough signal at 100,000 miles to get a reading

which is why it would not work.

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. wrdplay4 years ago
 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.
evilmadcow jj.inc5 months ago

satellite phones wouldn't actually work in space. their low range, power, and dependency of a SATELLITE TO BE POINTING AT THEM, when all the satellites are busy being pointed at the ground, makes it impossible. assuming your phone DID have the range for a signal to mars, and you could stand the forty-minute delay time, you could theoretically bounce the signal to another satellite with a dish, but the math required would be gargantuan, and not reasonably computable in time. it's literally like trying to play catch with a friend who is an a car. at several thouasd kilomieters per hour.

most of this is correct. also, no sentient life lives on mars.

Who said that the life would be on mars?

Also, while the chances of life being on mars is incredibly slim, we still have barely scratched the surface. Its the equivalent of Columbus thinking he knew everything about the Native Americans within a week. And all know how that went. We shouldn't fool ourselves with thinking anything is certain.

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.

... Liquid state IS a jet on a plane...(minus the oxidizer i suppose)

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.
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.

 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?
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
