Step 2: step2

ok so now we see the initial design, a liquid fueled ramjet rocket engine with o2 assist for upper atmosphere assistance. the fules I have chosen is "either" or starting fluid and "keyboarb cleaner"compressed air o2 for the accelorant and upper level assist.

now I was afraid at first to post this because of terrorist useing dirty weapons but because of its scale and the velocity of the fuel exiting the aerosol cans I dont think it is possible for it to actualy carry a dangerous payload.

here you will see all the devices I have planned for my orbital rocket

1st I describe the micro controler, a parallax BS2 homework board available in an education kit at Radio Shack for under -$100.

2nd I describe the calculator A TI86 z80 based programable graphing engineering calculator.avalible -wallmart$120 or a pawn shop under -$50.

3rd I describe the cellphone,maybe not everyone has one -under$100.

4th I describe the ignition system basicly a old flash cammera I modified into a "shocker" found here on i'ables and a automotive sparkplug

5th I describe the altimeter, accelorometer and FM Transmitter these are daughter boards available through parallax.com for accessories to the microcontroller sometimes used in hobby r/c planes roughly $50each.

6th the parachute trigger will have to be homemade or found for sale.

7th the engine and gas valvebody ,maybe a commercialy avaliable gasvalve from marine R/V propane heat under$200 if not it will need be machined 2-$600 estimated.

8th fuelbase manifolds homemade or machined under $200 estimated.

9th fuel & air must be calculated around $6 per can.

engine actualy came from a memory drawing of an engine I seen in an 1950's encyclopedia
the rest is prety much parts from a bobot kit from parallax,cell phone and a calculator I hobby with writeing programs for.

the can manifold bases and decision on fuels was all my idea.
<p>And also you would have to construct your own rocket engines. Hobby rockets rely on more on readily available oxygen from the surrounding environment, although the chemicals in them do produce a oxidizer but way up in the atmosphere those rockets would probably perform and burn poorly and wouldn't create enough thrust to propel the rocket high enough. The engines would have to rely solely on a oxidized fuel source to be able to perform well enough to break orbit. </p>
<p>I've thought about doing this and I still think of doing it till this day. Launching a weather balloon as high as it can go and then launching the rocket from there. Rather than timing the burst of the balloon you can razor the edges of the rocket, so when the rocket launches it slices through the balloon. While this is happening the energy released from the balloon can also help push the rocket but it would be hard to find a way to direct that energy in the right way. Your propellants I think would have a hard time cooping with the space enviorment, a can of duster would probably explode due to the vacuum of space. But this has inspired me to start working towards this goal again. </p>
<p>i am eleven years old in new orleans and i would love to pull this off with my dad i liked the weather balloon idea. what if 4 weather balloons where seperated by four long rods with a launch cylinder in the middle</p>
<p>glad you're young and interested. the wheather balloons wouldn't keep the same altitude each, since they don't have engines or a CPU that can manipulate their floating.</p>
Thanks I never really thought about that.the only way it could work is if you had one balloon that launched the rocket for balance
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&nbsp; 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&nbsp; the atmosphere is about 1% of&nbsp; 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&nbsp; 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.&nbsp; best i can figure hobby rockets reach 2000 mph on a ground level&nbsp; launch, maybe wrong though. if i succeed ill post video on youtube. good luck.. dave uk.
<p>+daveinUK Dave, the hobby rocket kits would probably not work to get you into orbit. You might want to consider liquid rocket fuel. I dont know if the acceleration would be high enough to get you past the upper atmosphere, you might want to buy some heat shields also to stop the friction from burning the rocket.</p>
<p>.....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. </p>
<p>&quot;some puncture mechanism&quot; would work, but it would be easier to just put a filiment and relay around the ballon. Close the relay, and the coil melts the cord.</p>
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&nbsp;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.<br />
<p>Mars and wormholes are not even mentioned.</p>
<p>Did you even Ctrl+F?</p><p>Better read the whole thing before commenting.</p>
&nbsp;If your phone was a&nbsp;satellite&nbsp;phone it might work, but if not it wouldn't get a signal in space. &nbsp;You could try one of those tracking phones. &nbsp;I like your enthusiasm and I really like the idea. &nbsp;One I actually have a good fuel supply idea. &nbsp;Normal rockets use hydrogen and&nbsp;oxygen&nbsp;so the provide fuel and stuff. &nbsp;You could boost it to a good hight with solid boosters, then drop them when the air gets thin. &nbsp;Then, using&nbsp;electrolysis&nbsp;create a hydrogen/oxygen rocket and you shouldn't have to separate them unless 5000psi would fuse them back together.
<p>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.</p>
most of this is correct. also, no sentient life lives on mars.
<p>Who said that the life would be on mars?</p><p>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. </p>
<p>hey if a bunch of kerbals can do it, why can't we?</p>
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
To all of you people saying that satellite phones would not work, you are wrong. there are satellites that are much further away.
<p>BTW wormholes are not proven and you will need over one billion dollars to get to Mars...</p>
<p>Take sample sounds of space. I'm face-palming sooooo much right now.</p>
<p>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.</p><p>Aidan,</p>
<p>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: Charlesdorksquared@gmail.com I wish to speak with you soon. </p>
<p>Sorry to say, but maybe you should learn to spell before you start asking people to donate thousands of dollars to someone who does not know how to build a nose cone in the first place...</p>
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
<p>GPS would not work outside of the position of a geostationary satellite.</p>
<p>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 </p>
<p>which is why it would not work.</p>
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. <br>
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.
&nbsp;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 &quot;separation charge&quot; which does two jobs: separating the boosters and ignition of the next stage. <br>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.<br><br>www.youtube.com/watch?v=N8KrEvT-wYQ
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?<br />no? <br />how about death?<br /><br />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. <br>you're just molding rubber.
Its not illegal and i dont think he was gunna launch himself in the rocket.
