hybrid rocket engine (sort of)

- taking another shot at producing something that looks like a rocket engine from a tin can and compressed air. Produces zero thrust, but it is a very efficient heat generator...
I've been getting a lot of questions about what fuel i am using: it is just newspapers rolled up into a tube and soaked in gasoline.
pretty freakin sweet for newspapers and compressed air
Used to do something similar to create a small blast furnace. Injected air in a spiral pattern into a can with oil soaked papers. Could melt the can!
I'd bet there IS some thrust to that, there has to be, after all, you are adding heat to compressed air causing expansion and rapid expulsion.
F = dp/dt
if there is aceleration in a mass of gas, so there is thrust..
I suggest something with more BTUs? Try motor oil or diesel and motor oil and then use a propellant of NOS. If it gets hot enough, it should split and look awesome.
although it works pretty good, and it looks like it was made at no cost, which is always excellent, did it occur to u at any point that its not a good idea to use wood in an engine?
One serious nozzle you got there :D
That's genius! What's its total impulse? Is it possible to use in a rocket? You should try it! Genius! A simple soup can... pure genius. What did you use for fuel and oxidizer?
Anyone else reading this can say I'm wrong, for that I can apologize. The concept is loosely related to a scram-jet if you could only get the air coming through in greater volume and at high Mach speed, just throw fuel into it and the compressed Mach air flow will combust it and provide thrust with no moving parts it's not even an engine. I did machining of components on the X47 launched off the end of a Pegasus rocket to reach the necessary speed for the scram-jet to work, keep the fire's out!
any actual thrust or does it just look like it? Can't imagine it's much more than just the force from the compressed air, very little from the combustion of the gasolline
Dang man put a leashe on that thing MAN! It's lethal yet COOL!
That was awesome.
lol@emergency procedures
-squirts water on the damn thing-
XD
i have to say that very original and engenious!
I think it is more like a welding torch than a rocket because the flame coming out is obviously very hot but there is little thrust.
haha i love the dousing with water.
whoa there fella, now , with a little refinement, a high temp ceramic chamber liner, nozzle and holder, you could REALLY have something here. IF perhaps you would attach this to the tips of two gimbal mounted airfoils (see NASA specs), with tuning , it COULD actually propel them fast enough to make a 'backpack' helicopter. The USAF experimented with such way back in the 60's. Check it out....!
Thats insane, please make a detailed how-to! I would feature your vid on my page if you did!
would this really have any more thrust than just using the straight compressed air??
My apologies for not being clean. I meant to use oxygen or nitrous oxide as an oxidizer for the newspaper fuel instead of just regular compressed air that the video was using.
why do you think theres zero thrust?? put a rolling chair with 50 lbs of weight on it in front and see what happens.. youve got plenty of thrust
zero thrust eh? is that enough to get to the mun?
Mun? This is real life not kerbal
and also just so we are clear a hybrid rocket motor consists of 2 things a solid fule and a liquid or gasious oxodizer like parifin wax and nos (NO2) or maybe somthing a bit more hi tech like oxy cetaline and solid sodium thows combinations are highly volitle but could prove more then efficent in launching a rocket out into space....
looks and sounds pretty cool ;)
you dont know how jealous i am! whats actually burning because i know that compressed air itself is not flammable?
what were the sparks at the end?
It looks like it has the power to move a matchbox car ^^
This would make a nice torch though:)
What you've made is a giant bunsen burner.
Cool, but what could it be used for? Looks more like a blow torch then a rocket motor.
lol ahhh its on fire *mum wheres the water pistal!*
btw a better fuel than that tha happens to givesmore thrust is polyethelene hose bunched up inside
@thumasta666 if you read the description it says that it doesn't produce any thrust
@G3org3Master
fire can also eat CO2 and produce coal and another oxide
thats why you cant use CO2 extinguishers on burning metal
it sounds cool
ooohh i thought you just had it mainlined to a propane tank with no regulator and just put it on low at first, then lit it, and then ramped it up...thats how id do it anyway...longer run time. btw how long can that thing run anyways?
great! now go strap it to your back and be the first person to fly to the moon without a rocket ship!
dude this is sweet what is it just regular propane?
Hmmm? Why do you think no thrust is developed? Could it be that you do not have a rocket engine nozzle in there . i think it is called a Bournulli Nozzle.
What would happen if you changed the news paper to paper towel?
@DrGreTuLR ,Hi,was that wood or ceramic at the end at the flames?
That is so cool :)
what were you pumping into the can? propane or something of that nature?
What the fuel ? Gasoline and compressed air ?
Try 30% gas and 70% diesel. Diesel has a higher BTU content than gasoline but is harder to ignite; that's why you have to mix gas in with it.
If you want a rocket, you'll need an oxygen tank.
did you connnect it to dinamometer to count a propulsive power???
because it is fun to watch shit blow up...
how is that wood not instantly incinerating?
try parafine mixed with charcoal they say it gives a good boost too
air compressor+ fuel?
it seemes to match the combustion chamber of a turbine engine and it can be done.
increiblemente peligrosos. . :O
pero interesante..
nice!
to make a real good rocket u shld get a water blaster but instead of putting water thru it put petrol thru it and light it up
Fire roasted tomatoes...
nice
Dude was that a can?
Would work much better running nitrous oxide or even pure oxygen
how fast could it go?
Oh, I just found out. Never mind!
wait what aluminum melts at 1400 degrees right
The steel is tin coated.
cool dude. post a video how to make ur own engine.
how did u make it
how do you build it
how much psi are you pushing.
make it fly :)
it looks more like a LPG gas welding unit...
can you make a tutorial?
dude! put charcoals in there next time
y dnt you attach it to something
just compressed air and gass your best off just using the compressed air for a rocket motor this is not a hybrid rocket motor this is just somone messn round in there back yard with a home made blow tourch
thats scary :)
Self sustaining.
wow
can u stand right behidn it and show us a video?
lol im making smaller versions of that with hopefully more thrust so i can strap them on my feet and be like iron man lol no jok i swear im goin to....but u shuld strap that to a car or yur feet or sumtin
green place
KOOL
great, you have built a furnace by accident.
i wanna make tht!!!!!!!
actually hes using a compressor..
hehe you need lox, otherwise use rocket candy and a thrust cone...
thrust? no more than 2-3N :))
It couldn't even push itself
the hillbilly hybrid rocket.
it wouldnt run on pure oxygen...it has to have fuel...mix it with like hyrdrogen or acetalene then were talkin
think of if you actually put pure oxygen to that.
danm put that shit on a bike.....hehehe do it hat janx would go fast
@SoNDgs
yeah rly
Spray pure oxygen thru it...then you have a rocket!
@guiltyguildleader o rly?
pegou fogo kkkkk
i did this and it melted the tin can
ogpaliłbym od tego papieroska oj odpaliłbym :] ale sie puszka po owocach z puszki nagrzała
huh?
motor jet
für was wird sowas denn genutzt? oda is das nur aus scheiß gemacht?...
@ficklefab fire eats oxygen and shits CO2
NITRO ohne auto :) :) :)
use seramic tiles and use a differnt fuel too much carbon was produced ruining your motor
More like a glorified lighter.
это что за твою мать?
why on God's earthwould somone build a rocket out of wood !!!!!!!!!!!!!!!!!
nice try though
