Jim's Valveless Pulsejet Engine

[phadil]

What type of fuel use and what's the fuel consumption rate?

[sberg32]

Nice space heater

[MMX3SE]

I want to see it cool back down

[FUCKisrahell]

taste like hot.

[DynaDuctINC]

The sparks coming out of the top nozzle is the carbon in the steel burning.

[MrRogueBot]

TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT TOUCH IT

[Riggormortus]

Hey Jim! Its Mike from August Enterprises, just found your video, COOL AS HELL!

[dieselducy]

That thing gets hot!

[vil64]

You did a great job making that beast. My question is how can you use it? You can't fit this into a model plane 'cos it would burn.

[killer013ful]

DAM!!!!



[TylerReedsMusic]

hmm..now touch it!



[bennyworldwide]

That is fucking cool!!!!

[jednootenboom]

spray some cold water on it....hahahaha

[Deathstar11978]

these things are really impressive......but i still struggle to understand why u make them :)

[inspectorcritic]

It makes a nosie will it go anywhere?

[brandongeiger2]

what does the curve do exactly like why wouldn't it work if you just chopped off the curve and ran it like a normal valveless jet

[ShasOFish]

@brandongeiger2

Probably just to let it fit in a confined space.

[illidur]

@brandongeiger2 see the fire coming out the intake? its curved so that blowout from the intake doesn't go against its propulsion.

[TheBackslash1]

*tries to fart as hard as that thing just did*

[AaronISB]

This may be a stupid question but if one is the intake and the other is the exhaust then why are flames coming out of both of them?

[nasanasa3]

@AaronISB valveless pulsejets constantly alternate.

[DIRT3GYMKHANA1]

put your dick on the lightsaber"!!!!

[27CLUSKER]

ive gone deaf and so has he

[hristijank2]

hahahah xD i actually laughed at the text box that says: "do not touch!" xD

[Steve181]

I guess that's what the Nazi V1 rocket sounded like.

[Agrimoths]

But the question ist -- > Will it blend ?

[deoxynchro]

what the heck. i came from sweet child o mine guitar cover then i end up on this.

[clarissafulkner22654]

hihi come to my room I'm all burning

[spartan7126]

what did you say

[MrGruaba96]

the name of the pulsejet is " hot dog " :D

[FlexxArtist]

Thanks for this, I just watched a Justin Bieber video to take the piss out of him and I needed to re-insert the testosterone I lost in that moment of time.

[nosehacernada]

tengo que hacer uno igual para la universidad por favor me pueden ayudar con los planos

[violabonbon]

need that on my car :-)

[irelandbloke]

Cool

[joshyperk]

is that Chuck Norris's Heater?

[EpicScandinavian]

bet that makes one hell of a shop heater

[neonbluen851]

that pipe is about to melt

[malehakhanam]

hihi i am an uk girly

[nuke583]

how do you stop it? put some sort of cover over the intake hole?

[giannba]

@nuke583 Just cut the fuel circuit

[Jeffnz020]

@nuke583 Shut off the propane supply, how else do you think it runs?

[LifeforArt]

99% of power is used for heating a steel-tube and making noise, 1% for thrust, but another 100% for having fun!

[jonesy66691]

doodlebug engine



[kcollspac]

hollow all the way through

[mikeBURRITO]

so is there anything inside of it that pushes air through or just the suction from the original blast of air?

[tautvydukass]

i'd like one of those on my bike

[Dayao12]

So what does this do? does it create propulsion?

Why do I imagine those Star Wars racer things from Phantom menace? lolz

[Dayao12]

@Dayao12

nevermind...just googled it =P

[offroad2madness]

mmm hot curry



[kingmanted]

If there was one small flaw in that metal,that whole building could get pretty fucked up i think.

[flanksteak2]

Why for your intake have an afterburner?

[headjammer]

looks more like it would heat a garage better then anything else

[lovelygirl9191]

hmz just turned 18 and want to learn what fun is all about

[torquemenistan]

The red hot motherfucker!

[gustavo44367]

eitaaa porraaa 

[MadCow10123]

How do they work?

[sk8ingonfire]

what about adding metals - like a cat converter uses !!

[clapp62]

BTW, the German V-1 had almost 800 pound of thrust vs. 50 here. I can only image the noise it made.

[skyprop]

@clapp62 Really loud. Do a youtube search for "V-1 Audio/Sound" and you can hear it



[clapp62]

These things were used on the German V-1. How terrifying it must have been to hear this thing screaming over head and then silence just before it hit.

[mobeus5019]

seems horribly inefficient. Alot of heat for not alot of thrust. But still, very nice.

[mccelf]

@mobeus5019 Pulse jet engines aren't really famous for being efficient.

[mobeus5019]

@mccelf Touche salesman. For some reason, the Undergrad Aerospace in me kicked in and was like waitasecond, thats a awful thrust to output ratio.

[maxpower700]

up to 50lbs of force on the exhaust, white glowing hot-as-hell metal, and it DIDN'T bend itself? what the hell did you make it from? forged reinforced hardened steel to 10.000degrees C? LOL

[LeMieux250]

lick it

[bahrainTVchannel]

Will it Blend?

[voon100]

@bahrainTVchannel Yes it will fucking blend just like your mom.

[bahrainTVchannel]

@voon100 this Valveless Pulsejet Engine remind me of your mom vegaina..

[xoxoXoieoxox]

do u think it will ever smelt it self??? O.o

[VortexNL]

Why isn't the intake also thrusting gas out? How is it that almost all the gas is coming from the short tube?

[fishchipsandpeasTV]

What percentage of the fuel's energy is converted into thrust. It looks like the majority converts to heat and noise.

[alexgd0193]

"I dare you to touch it..."

[PinoyPowWa]

i wanna touch it

[ugry96PLINK]

Hmm so interesting,using a lightsaber as jet engine...

[recacon3]

Dude, this shit is about to blow up! COOL!!!!

[apismellifera1000]

Hey Sheetmetalguru, Thats a cool Lockwood pulse jet you got running there. You may want to put some thrust augmentation ducts on the exhaust then mount it on a gokart. Cool vid thanks for uploading

[Grabowski420]

SS?? wont that melt??

[Harriisoon]

Surely if you were just to prod it, the pipes would just sort of collapse as they are so hot? It must be pretty much melting point right there!

[AnarchyEngineer]

Can someone please explain to me why the 'jet stream' (let's call it) is coming out of the exhaust and the exhaust looks like an intake (no flames etc coming out of it- looks like it's in taking)

[thestrokeds10]

@AnarchyEngineer because the combustion chamber is so close to the intake. th flame looks like it's "flickering" because it burns, then sucks in air, then burns again.

[M3iscool]

No hearing protection?!

[thistlechin]

chuck norrises dick after wanking

[TheDontlogoff]

@thistlechin



[B0bTheMelonMan]

holy shit that things glowing reder than the devils asshole!

[libertytennessee3709]

You gotta be kiddin me, I wouldn't get within 50 feet of something that glows WHITE hot, that sum bitch must be hitting 1200 degrees running temp, what about the propane feed tube melting down and WAM!!!! buy buy NECK? no thanks on that motor. As a video, big thumbs up!!! I can't dog the video, it's informative and high quality but the value of a valveless pulse jet = 0.

Seriously is there a way to control all that heat with heat sinking or something?? How a bout a liquid sodium jacket.

[Mazzzki12]

from witch pipe does the power come from?

[RippedWookie]

@Mazzzki12 Exhaust. The power will always come from the exhaust.

[niflap]

How much thrust does it produce & how much does it weigh?

[cobrachoppergirl]

I need that on my ultralight. Screw this rotax, I want a pulse jet engine. If I can just insulate it....

[Blueberry954]

@captinofpineapples You go ahead...

[captainofpineapples]

TOUCH IT!!!!!!!!

[BIGBEASTYBURGER]

but will it blend

[spotlightman1234]

I know lets touch that bright yellow pipe.

[efd5803]

This reminds me of the Bill Engvall bit, if after you drive a car, you grab the exhaust and say, "Dang that's HOT!" Here's your sign! That was awesome!

[Jonathan219234]

im surprised that the engine didn't explode. The metal isn't supposed to get white-hot right?

[MrInventWorld]

Nice.

[catklyst]

Jesus could you imagine those v1s during the second world war with this sound I would shit my pants if i heard that,

[imaudie43]

Hmm less shiny then what I remember

[Acelera89]

What happens if the metal were to crack/ break/ or explode ?

[boltjet135]

@Acelera89 some fuel, very hot flame and pressure. what do you think would happen?

[rube1995]

Now that... is one big fart

[FASTBOOBS]

YOU'RE CRAZY !!! THE MATERIAL AT THAT TEMPHERATURE CAN DESTROY AND break into 1000 pieces!!!!!..IN A SECOND!!! CAREFUL!!!!!!!

[dinosaursarecewl]

@FASTBOOBS or melt...

[biometal28]

I could see the potential hazard with this.

[scooterforlife37]

i liked the do not touch annotation. and why is there a flame from the intake?

[capetaquebratudo]

Why did you do that?

[ryfin2000]

@capetaquebratudo Why not?

[ecfnw85]

ill give some body a shiny nickel to touch it

[migueyeah123]

cool color.. can i touch?

[rox1317]

damn hot!!! how hot is that? Is it steel?

[SSPiota]

"do not touch"...but its so pretty

[spacetweek]

The quicker we get rid of fossil fuel engines the better. Can't believe this bullshit.

[Suprastar77]

@spacetweek shut the fuck up. without fossil fueled engines. half the world would come to a complete stop

[bassblair11]

no PPE?

[doyoung2win]

This is cool. It's like the drones from Battle L.A.

[shortinos]

Reminds me when i go to the toilet after a hot curry.

[Patrickclimbs]

how is that table not taking flight?

[porksmash1]

@Patrickclimbs intake and exhaust are facing the same direction

[almcken]

you forgot the marshmallows 

[1jimmarch]

"Do not touch." Really? I think it's more like "do not get anywhere NEAR this fucking thing!"

[OktoberStorm]

I'm speechless!

[robertoszwas]

Propane and Propane accessories‏

[colloredbrothers]

haha "do not touch" NO SHIT

[lullie0911]

Dear Santa....

[tenforce]

holy shit, i dont know what it is, but i dont want it to stand in my house!!

[TurtleSwagger]

Holy cocks.

[Melthornal]

I think he may have a cooling problem.

[servo310]

Dude, your neon light sounds fucked up.

[espiraldehierro]

disculpen mi ignorancia,para que serviria este tipo de aparato solo veo que se pone rojo por dentro ,¿no explota? gracias .de pachucahgo. Mexico xotene.

[flashfast2007]

@espiraldehierro esto es una especie de motor a reaccion, es el antecesor de las turbinas de avion, aunque solo son experimentales, se llaman pulsoreactores su unico uso es en el aeromodelismo, aunque hoy en dia se ven pocos, saludos desde españa...

[alecdepalect]

that is my read lamp :D

[K80sharpshooter]

A light bulb and heater all in one!!! Every home needs one of these!!!

[dodgedakotafan]

imagine add 4 to a go cart



[ironandbrass]

Hey Jim

What size gas valve regulator are you using?

[KATZENZITRONE]

Hi Jim

I've been checking these pulse jet videos and you're the only one who really shows easily how it's done and what's it take.

I just thought, have I understood right, that the base components of the engine are the spark plug, which can be made of metal and screw on. And other than that the butane fuel. What I want to know, is that can the fuel also be delivered through metal pipe so it wouldn't melt the pipe?

[jorjethezebra]

that is one sick bug zapper

[yamahonkawazuki]

i gave a thumbs up because the guy had the balls to stand there sans hearing protection :O

[bloodgasses]

JESUS !!

[kaidma]

you wouldnt like it

[felixcasio]

now I understand the importance of intercoolers.

[mejawmeyaw]

what is this metal ??

[Spaceman002]

@mejawmeyaw gotta be steel at a minimum...best would be a nickel superalloy lined with a ceramic

[jack9102]

the last frame of the video shows it exploding.. jk lol cool engine though, some of the miniature ones people make are cool too

[Podarias]

how much presure does your blower generate?i have built one but after i take away he air it stops...mine generates up to 8 bars...do you use propane?

[krazor8]

god damn, so when do these become avalble for purchase to put on a go kart

]

[jack9102]

@krazor8 why purchase when you can build one out of plumbing for 15-20$ ?!

[BikerFail16]

the light bulb has already been invented 

[sixsagoonj]

try touch it very fun

[assasin424]

Why is the intake shooting out flames?!?! that makes no scenes the exhaust should be shooting out all the flames? do explain please!

[Podarias]

@assasin424 the hot gases generated from the combustion come out from both the intake and exhaust pipes!!That happens because the combustion chamber is open at both ends, so the gases expand and go both ways. Now because the intake pipe is shorter the gases come out from it faster than the exhaust pipe itself, so the engines 'inhales' new air faster. That's why you see more action happening there

[Kx2fity22]

Dare ya to touch it

[128pro]

very nice. good run!!

[Jeffnz020]

His ears will be ringin for a month after standing next to that sucker!

[Danielkchoi]

I can just bet if you converted the heat coming from that thing into energy it would run 50x longer.

[vali45666]

can you touch it ??

[hugomaster50]

ima firin maaaaaah laaaaaazaaaaaaaa XD

[bostonj24]

did the spark plug melt?

[hud42cdo]

THAT SOUNDS LIKE IT RUNS WELL,AND SO EASY TO START,WE BUILT A REED VALVE ONE OVER 20 YEARS AGO-AND THAT WAS A S.O.A.B. TO START-neat.

[JOCKATEO]

pimped out crack pipe

[tsubakki1]

was kind of expecting it to droop over half-way through from it melting,

[DotCmaker01]

he is now deaf...

[amor00]

"Ground control to major Tom"

[Pasc1979]

Wow, glowing quite a bit.. Would make a great desk light if it wasn't that loud..

[iliveonjupiter]

Could someone open a window

[jims72]

anyone got a hotdog?

[b0bsaget007]

if you touch it, forget about burns, you'll just disintegrate/melt. ;)

[slipstream0011]

I swear I was just watching Minecraft videos a second ago....

[tvoice1]

This thing scares the crap out of me

[kaelwd]

when it starts to get hot enough to glow you can see what looks like bits of molten metal coming out the exhaust

[partyman6666]

I dare you to lick that engine while it's running.

[Carbide195]

I think the words 'holy' and 'shit' apply here.

[jonnyjb69]

hmm...seems to be gettin a bit hot there. lol

[ntaznsol]

rocketeerr

[offom]

How many bar/psi is this compressor ??

[BaahFuckOff]

@offom read : 35 to 50 lbs of thrust
