Armadillo LOX Alcohol 500lbf rocket

[juanadedios]

intersante el video , quisiera me diagn si en realidad el combustible que usa este motor a reaccion es exclusivo 100% alcohol, ya que ve que si produce una fuerza de empuje leve, aunque se necesita mas fuerza para poder lograr un empuje relacional al peso de la maquina y la fuerza de gravedad existente....me gustaria construir uno de manera personal, siempre fui un fanatico de los cohetes.

@coinageboy If you do some research on the lunar lander you will find some very interesting information and you'd probably find the answer to your question. Careful though there is a lot of mis-information on the web.

[tomboi1978]

@coinageboy simple. This is not the type of engine they used on the LEM. The uploader has no real understanding of even basic principles of rocket propulsion and must therefore attempt to "prove" his case by misdirection and innuendo.

[radumotisan]

stability with only a single thruster can be a big issue to solve

[sierra043]

it farts every time it cuts off

[kffive]

Damn, NICE!

[monsenrm]

I am always amazed at the moon landing hoax morons that decide they don't believe and then look for "evidence" to support their theories.

The tiniest bit of research and a modicum of gray matter shows no correlation of a much larger nozzle, massively throttled back, hypergolic descent propulsion engine operating in a vacuum to a narrow nozzle rubber/lox/whatever engine operating in air.

Oh well. They won’t be deterred…..

[gymkhanadog]

That thing has some pretty good oscillation control, especially for only being a single exhaust device.

[ZETTWIN]

LOL Летающия табуретка.

[TheZachoftheglen1]

flying school desk. lol jk nice :)

[ThoughtfulAtheist]

that would make one hell of a grilled cheese...

[zillionz]

can i go home now?

[CosmicDamian]

Check out the most recent images of the lunar landing sites taken from satellites. They're only going to get sharper and sharper, making hoaxers look more and more foolish.

[lolle18]

@CosmicDamian Next step of the hoaxer is: "That's of course photoshopped. I can tell by the pixels..."

[CosmicDamian]

Check out the most recent images of the lunar landing sites taken from satellites. They're only going to get sharper and sharper, making you hoaxers look more and more like paranoid idiots.

[dansmith57]

yes, you need to learn more about the finer dynamics on how materials such as dust on the moon work...........

[fleafrier1]

Ist, ditto occhamite's comment. Take an oxy/acetylene torch to concrete and it will do the same thing, while producing very little actual thrust. Where safety glasses if you try it, BTW. 2nd, Thanks for including the link to the LM photograph in which can clearly be seen patterns in the dust radiating out from under the descent engine nozzle. Gee, I wonder how they got there? Very nice video, though, if a bit misinterpreted.

[magna59]

Very impressive......who need the flying beadstead, when you can get a flying coffee table ! Keep at it you guys.

[mypyro2]

how did you make it

[ThiagoMarquardt]

Really need fasters actuators for the thrust vector control

[AndreisEntaro]

Please normalize the volume on these rocket videos or place a warning in the top of the description.

[david1513]

not sure whats going on here but alcohol burns blue and dureing the day you can't see the flame? plus the things top heavey it would just fall over if lifted off the ground by the bottom like it is ,,weight forword thing i build rocket this is what happens,

[raveman100]

r.i.p my headphones

[acidalby98]

useless jetpack

[aeastes11]

You conspiracy people are hilarious

[Kai420yee]

wtf are you guys talking about

[Slugg0matic]

FWIW the LEM was down to 20% thrust before landing and it had a larger engine bell for a broader distribution of thrust than this pistol-butted rocket, and as stated by NZbobNZ, it was shut off somewhere around 6 feet before the legs touched the surface.

Did we land on the moon or was it a hoax? Doesn't really matter to me one way or the other but I've never seen any of the hoax pics or stories stand up to REAL science, and I've seen tons of them.

[6541Alex]

I wish to put my meat down on the engine

[occhamite]

@trodas This video of yours proves nothing except that you do not know what you are talking about: The flying debris has ABSOLUTELY NOTHING to do with the thrust of the rocket, but is the result of a phenomenon known as "Explosive Concrete Spalling". The HEAT (not the thrust) of the rocket flame produces stresses in the material; due to thermal expansion, as well as pressure due to trapped superheated steam. The result is chunks of material flying off. (cont'd)

[CDennis402]

@occhamite what? We never went to Moon, drink more kool aid stupid

[occhamite]

@CDennis402 Huh? Quit drinking altogether, genius.

[occhamite]

(2of2) Question: Why do you suppose it wasn't until around 00:50 the debris began to fly? If force was the cause, the effect should have been immediate. Could it be that it took time for the concrete to heat-up, and steam to form inside? The same thing can by done with a propane plumber's torch (heat, no thrust). A burning vehicle in a concrete highway tunnel will sometimes produce flying concrete shrapnel.

DON”T THINK SO? Google “explosive concrete spalling”. Take this lie DOWN.

[NZbobNZ]

hahaha at 0:50



[Fontomovsky]

The LEM descent engine was turned off at around 2m above the surface.

[Postie218]

Listen, you guys fix this up and get it all worked out working fine. Then, you bring it to my house, we'll hook my video camera to it, and take pictures of the two hot babes that live next door who spend most of their afternoons nude sunbathing.

[benscardude]

freakin amazing

[rpblcan]

not moving up....

[Gracana]

@rpblcan There's no sense in letting it get too high only to fall violently onto the tether. All testing can easily be done just a few feet in the air.

[rpblcan]

@Gracana what for?

[Gracana]

@rpblcan This looks like research/testing for one of Armadillo Aerospace's Lunar Lander Challenge entries. The challenge is to perform a vertical takeoff and landing with sufficient thrust to be successful on the moon. VTOL requires exception hovering ability, which they seem to be working on in the video.

[hulago1234]

propellant thrust = total weight of load

therefore it will forever stay aloft

[monzter555]

cool!!!!

[NelielTuOderswank]

And perhaps the center of your retardation, space is an insulator. No heat escapes, because there is no matter to convey the heat, which only allows for radiation of heat. Because of this, the hot gases from the engine cannot impart enough heat to the lunar surface to create a crater or burn-mark, because they simply are not in contact long enough, as conduction is very poor between gases and solids.

[NelielTuOderswank]

Even worse, you fail to understand Bernoulli's law, the standard for all forms of flight. The moon is a vacuum, because of this, rocket's cause much less backdraft because there is no atmosphere to bite into, which in turn would create a vacuum, pulling even more air into the backdraft.

[NelielTuOderswank]

Trodas you utterly fail to understand the concept of an engine bell. Cooling is not a problem. Furthermore, the moon is not just a big pile of dust. Its a layer of regolith only about two inches deep, under that is solid rock. Any dust blown away would just show a slight depression from where the dust departed from, no crater.

[hendricks217]

in a near vacuum, gases disperse much more quickly, and when the lunar lander was near enough to the surface of the moon to actually effect it, its engines were not operating anywhere near 100% thrust.

[occhamite]

OK trodas, time to make a decision: Tell the truth or lie. No crater digging occurred in this video. You can do exactly the same thing to concrete with a welding torch(heat, no thrust)that the rocket plume is doing. Any welder will tell you concrete explodes if you apply a flame to it. Now you know, so which will it be, truth or lie?

[ltnrig]

The lunar dust is vacuum welded. What is more, the dust cannot weather, so its incredibly pointed and sharp (so it sticks to itself very well). The regolith is hard stuff and not easily cratered.

[datzfast]

@long pointed and sharp doesnt stick to each other. try using science in your statement. sharp rock does not interlock, it doesnt penetrate each other. its not magnetic, it doesnt compact well, it doesnt retain electostaic forces, in short is simple pumice. minus the moisture of course. and i find your statement false and intentionally deceptive, that makes you a creep. i know your innocent because your just parroting words you have read in a book, that makes you a dangerous creep.

[colinshark]

Nothing happened to the concrete, you complete moron.

Awesome footage, by the way.

[juro080]
