[RutinaRottis]

Putting that in rc-plane? Are you mad?

[rafarocket]

RIP headphone users

[graffist448]

thats a brave man.. walking in front of the engine that way... I'd have never ever done that

[brssgirl]

flames are coming from the intake? is there no way to design a venturi that will take advantage of this to suck in even more air?

[timhardstyle1]

let's cook some eg's on it?

[Officer94]

try to touch it...

[reddeamon1996]

try puttin your dick there now...

[MrForeverfreedom]

and now....press your balls against it

[MrSafirius]

tooouuucchhh ittttt

[soadpsycho19]

my vaccum is on fire... hmm, what do?

[TheNoisePolluter]

Will make a useful alarm clock.

[FlexxArtist]

How do they work?

[pcferret]

But will it blend? Or fly? Bench test away!

[Groesbeek1994]

now grap it :D

[wikieditspam]

Invest in radiators and heat sinks.

[BeynenHater]

propane tanks in the back and a red hot pipe a few feet away.Try bringing the propane tanks closer,usually safer that way/

[BeckTechnologies]

@BeynenHater First of all, the camera man can stand next to the engine, and even behind it without catching on fire. Second white paint reflects away what little heat there is. Third propane expands so much in volume that it cools whatever container it is in as it is evaporating in the tank. And lastly, a jet engine shooting exhaust out the back at 500 mph means that a lot of cool air has to get sucked in from in front of the engine.

[marek0086]

@BeckTechnologies~ whats the max decibels on one of these?

[gh3mindfreak]

@BeckTechnologies so basically you have this long explanation that stills says what common sense? i threw that out the window a long time ago

[Az3arization]

@BeckTechnologies yes true , but you forgot to say that the propane tank is inside that foam-like isolater first , and second , in cold winters you can sometimes hear the gas inside the tank boiling , propane boils at 0.5 degrees celsius so sometimes you need to heat the tank a bit !

[MRcanadaification]

i still dont get it !!!!!!

[infiniteFTW]

Lick it.

[pogonip8532853]

how the hell do you cool it?

[madisolen14]

is that warm?

[TheNakedasshole]

can i touch it?

[darktide31]

WHY?? That is weak, look at all the propane behind that crap.. looks *safe as hell* to me!!! That is such a dumb R&D mistake they made. I don't trust it.

[skutits69]

Holly crap! That thing is scary as hell!

[NonDairyCreamer77]

that looks hot as FUCK

[1mrhiphop]

WHER IS THE ENGINE?

[zillionz]

@1mrhiphop lol

[VinnWi]

Put water on that @-@

[iTzZTrApPed]

anyone has a sausage??

[anthony3leaves]

does it need fuel? and if so, were does it go?

[zillionz]

@anthony3leaves lol, some peoples questions are so dumb

[anthony3leaves]

@zillionz stfu, i was sirtain it needs fuel, i just didnt see anywere the fuel intake was

[jrw6137]

OMG DON´T TOUCH IT!!!!!

[diegonikki]

most powerfull vuvuzela ever

[muva2000]

@diegonikki best comment ever :D

[kkkInSanity]

thats smart lets put propane tanks right where it would fly if the mount broke...

[eclipse245]

I love how there's propane tanks like 2 metres away.

[franguex]

safety first! this shit near gas cylinders can be a problem ! LOL

[soicansee1111]

looks dangerous

[buttmanroad]

Why not a Thermal Jacket with Super Cooled Gas wrapping around the main. Perhaps Baking Soda? Just Saying.

[skaterboy2711]

i dare you to poke it

[YottaFlop]

@skaterboy2711 Yeah! Poke it with a stick in the white parts!

[MonkeyWithAWrench]

@junmiguel2007 yes, but the cost to build it is greater and they have a limited sevice life of about 30 minutes untill the valve petals snap or chip. the valveless can last as long as the metal will, and if made from stainless, that can be years.

[chair5432]

beck technologies, leave this overrated shit alone for once, what a horrific looking contraption

[Adaboo124]

so ugh why is that soo hott? lol seems like a dumb ? but why?

[14GauLeiTeR88]

was is das ;D

[neo2024atsagichnicht]

That`s what you must do with all the gas- and paint cans in the background...Verry amazing video but when do you upload a video call`d : "how i blow`d myself up" ???

Gr.

[Coyote575]

Is it throttled with fuel?

[MonkeyWithAWrench]

@Coyote575 yes, simular to a diesel engine. more fuel=more thrust

[imthesonofjorel]

looks safe with all those propane tanks in the background

[HouseForLife6]

So does this basically work just by filling the chamber with gas, and then lighting in, and suction & combustion does the rest ?

[SNDYourMother94]

Let's all touch this awesome orange/yellow pipe :)

[23spacecase]

i was waiting for a rock to get sucked up

[Podarias]

i have built one too but when i stop theair suply it doesn't sustain the combustion.it generates a lot of flames but it doesn't work on it's own...how much presure do you have with air?

[55dcyinely]

I tried building one like this, but it doesn't sound anything close to being as fine tuned. As your is.

[AgentCROCODILE]

tuba from hell

[inferno922]

cool

[cobrachoppergirl]

If you fed inert ammunition from a hopper at a steady rate, the same diameter of the pulse jet outlet pipe into the exhaust pipe, to propel the ammunition using the jet of air coming out the exhaust, would such a resistance (propelling a projectile out the exhause) interfere with the the function of a pulse jet engine?

[MonkeyWithAWrench]

@cobrachoppergirl yes. i tried this with water injection on one of my engines. it changes the resonance of the tailpipe due to the increased inertia, causing the intake cycle to stop.

[falaqdad15]

how do you stop it?

[TheDarkvader13]

love the orange pipe :D

[tobilius2008]

Looks a little toasty...



[lefterismetalas]

can you give me please any designs of this engine?i want to make one too...

[Podarias]

is there any designs of this engine online?I want to build a Pulsejet myself....

[MonkeyWithAWrench]

@Podarias google pulse-jets. c o m . they have free plans that can be made out of parts from the pluming store. i think that jet is called "the ugly stick" pulsejet. but, it sure does run!

[RichardOhKaNoi]

@Podarias might try asking the Germans they developed it in WWll for there V-1 rocket. and i guess if you looked up the V-1 engine plans it would be on line.

[jimjimthehumanbin]

they used a pulse jet on scrap heap challenge. probably a clip of it on youtube. lovely simple design. would love to strap one to a glider or other light aircraft and see how it does.

[tomterahedrob]

Is the valveless design more fuel efficient than the reed valve pulse jet? would this design have the power to weight ratio to be a good substitute for the Jet Pack?

[MonkeyWithAWrench]

@tomterahedrob the reed valve type is more efficient and has a better power to weight, but the reed valves fail at random times, usually about 30 minutes. that makes the less efficient valveless better because they have no moving parts that can fail



[MrHeavygamer]

you could heat your house with that

[mgibbs88]

What would happen if you touch the red part?

[cancareless92]

AL Gore would not be happy about this...

[Themayseffect]

can this be modified into a dynajet?

[AKhiker343]

GOOOOOOOOOOOOOOAL



[GeneralRimmer]

CAN I COME OVER AND ROAST COCKTAIL SAUSAGES FROM THE FLAME XD LOOKS FUN FOR A FIREWORK

[sariH512]

smart idea to put there near those tanks bottles thing xD

IDIOTT!!

[domenicbobby]

sounds like v tec just kicked in YO!

[femanvate]

That engine's pretty amazing.

How in the world would I mount this on a RC plane without it roasting everything around it.

Maybe on a raised pod???

[ipodmaniac97]

Can i touch it

[buddhafollower]

i would like to see that engine working with water:) instead that fossile fuel...

[Ian400ex1]

@buddhafollower well, thats a stupid idea.

[Lordofdragons16]

Wow, that's like the barbecue from hell.

(Propane joke)

[radicalnegative1]

Are check valves needed in the fuel system at all? Is there any chance of a "backfire" into the fuel line?

[tuchicilina]

that thing is HOT

[Chardiieee]

I dare you to throw a bucket of water on the parts that are white-hot :D Trololol

[AgentCROCODILE]

Leafblower 2.0

[dbedioui]

if you were able to ceramic coat the combustion chamber you would get a lot more life and performance out of your jet....however its still a neat project

[parzifal2]

very dangerous

[GayBoyRunning]

which is the in let & which is the out let?

[xsniper3500x]

right wtf is with all the tanks near that man

[tronicson]

... or how do i make the greatest noise on earth!?

[toribasher123]

i dare you to put ur dick on the hot tube

[kapufa]

vuvuzela!

[Jeffreyshnigity]

I dare u to touch it :)

[hangoutsumtime]

what gauge steel

[BowHunt1229]

hot metal

[moogleye]

wow now you just need to attach wings and a few tanks so it can be a model airplane....... (the plane must look retarded)

[BeckTechnologies]

@alwin523

And how's that going to happen, you can stand next to the engine without catching on fire. The propane tanks get so cold from gas expansion that they form ice on them even in 100 degree weather.

[Andre232323232332323]

@BeckTechnologies i know his wrong... but is it really necesary to put the pulsejet right beside the propane tanks? just saying no ofense intendet

[barronerik]

@alwin523 pussy..

[zythepsarian]

the only problem i ever see with these things is, IT RUNS WAY TOO HOT.

[DJVAUGHN]

DO U THINK U CAN MAKE IT SMALLER LIKE

L: 5in

w:6in

[coondogtheman1234]

not good to have propane tanks nearby when somethings glowing.

[monstercameron]

so you injet air or something

[SquareYourFace]

What's this advanced injector you mention?

[essenem420]

why in all the pulsejet videos I've seen does no one make any efforts at cooling? won't welds eventually fail or something?

[Ittal]

@essenem420 Welds wont fail, as long as u can use a TIG When the most pressure are going out the exhaust

[Laofse]

Could you make a pulsejet out of regualr exhaust piping for cars?

[asst9999]

you could try it possibility of explosion is low

[theleakytaps]

how much thrust do these make, enough to puse a minibike or gokart?

[BeckTechnologies]

This one puts out about 25 lbs thrust. 50-70 lbs thrust works well on a gokart.

[ioan21121221]

so these things arent very powerfull compared to their size compared to other jet engines?

[madnesscombat5]

compaired to their weight it produces FAR more thrust. and i think by size you mean weight :P also it has no moving parts so these things are cheap as hell too.

[MUKULIADESIGN]

im sure it would be pricey. but if you cut one of these out of high heat steel alloy bar. with fin like heat sinks. ran a shroud overit with a fan sucking air into intake and blowing over heatsink fins. it would cool alot better and be quiter

[BeckTechnologies]

Congrats, you just found a way to turn the worlds simplest engine into something just as complicated, expensive, and hard to make as a turbine.

They have no internal parts that need cooling, the hotter you can run them, the better they will perform. Same with turbines, except turbine parts will melt and explode over a certain temp.

[MUKULIADESIGN]

actually if u have access to scrap bar and donated cnc time. depending on scale this could a finned cnc cut version with a shroud and a fan that could use same electrical as spark to start motor and be driven off of vacuum at higher throttle--- could be built for several hundred dollars. also valves that could kill gas flow - and a coil that could deliver spark anytime. could throttle engine on and off even in flight if the electric fan could be used to start it

[newdecade]

wonder how many uses that metal tubing can withstand before it eventually fails?

[BeckTechnologies]

As long as its not abused, like having water dumped on it after its running, or poorly mounted so that the forces damage it, they last a long time. I've run a few engines for many dozens of combined hours with virtually no sings of wear, I've never had one wear out or break that wasnt an extreme condition or intentionally destructive test to see just how much abuse they could handle.

[tropangUDO]

how do you make throttle control? is it just controlling the amount of gas you put in?

[tekkentool]

yes

[Gammaclipper]

A million billion trillion gazillion tons.

[rcfreak2493]

lol

[mikez2]

how did that not burn the hair off his legs

[BaseStationZero]

He shaves them? :)

[tomixx6]

alguien me explica como funsiona? gracias

[egarzavaldez]

Es un motor muy simple que funciona generalmente a base de gas propano, son 3 partes, la cámara de combustión que es el cilindro mas ancho y corto, el tubo de admisión de aire, que es al más delgado y corto, y el tubo de escape que es el curvo y más largo, genera una propulsión menor a la de un motor jet, pero como vez es muy simple, este motor es el principio de propulsión de las bombas V1 que Hitler lanzo a Gran Bretaña en la segunda guerra mundial. Saludos

[tomixx6]

muchas gracias valdez te lo agradesco

[vonlyf]

Dear Beck Tech: CRAP! MOVE THOSE PROPANE TANKS

further away and to one side of the engine!! That thing could melt loose and drive right into one!~ otherwise great build. I've been to Hiller and seen the protos... amazing.

[Gammaclipper]

I don't know that it has sufficient thrust to break free and fly into the tanks. I am curious as to why so many of these are bent the way they are.

[crezzyman]

Smaller package, easier to put into something, makes more thrust for the size, more effective.

[Gammaclipper]

Actually I looked it up. Turns out that unless a valveless is moving at a pretty good clip the exhaust will come out the intake and reduce the thrust unless the intake is bent back. This makes it harder for the engine to suck air against the stream when it gets moving but sticking thust augmentors featured in other videos over the intakes would help with this. Another interesting design I've come by is wrapping the fuel line around the exhaust to put some of that glow to work and vaporize fuel.

[BeckTechnologies]

There is no appreciable difference in the engine breathing with a rear facing intake statically or at high speed. Depending on the type of flare you use, you can actually get significant ram air pressure with a rear facing intake.

[Gammaclipper]

The now semi-inaccessable paper still hosted on your site by Bruno Ogorelec seemed, to me at least, to tell a different story. I'm not certain who to believe yet but it would seem that when an engine is moving that having the intake bent back could be a problem for drawing air into the chamber at sufficiently high speeds. But since most pulsejet craft don't fly faster than mach 0.5 it wouldn't be a problem in most cases.

[FireIwithoutIwire]

...oooooh yea

[redm7441]

ROFLMAO Viadimir

[xXtortionXx]

touch the red part!

[BeckTechnologies]

That would be very bad for the metal and welds. The bigger engines at low throttle I can actually stick my hand in the intake because of the unique running characteristics of the design, but you shouldnt do that unless you are willing to be burned very badly if anything goes wrong.

[kristovanskilazy]

chuck a bucket of water on it

[casey963]

Stick youre finger in the air intake, I dare you.

[KanzlerM]

Tssss... ouch!

[vladimir2277]

More like Tsss... where'd my finger go???

[BeckTechnologies]

Check my other video 'sticking your finger in a pulsejet engine' I did it with a much larger engine.
