WAIT! ALL THESE YEARS IVE BEEN MARRIED TO A PULSEJET AND I DIDNT EVEN KNOW IT!

Make it so small that the sound it produce is over our hearing frequency, that would be cool. Some grams of force but not a single sound.

Incredible! soo small and so high frequency

Thanks for your video it showed up a lot of faults with pulse jets but it also provided a lot of answeres. I have machined up a version that takes advantage of the wasted heat,in doing so, heats incomming gases while cooling the motor internals, this should also reduce. decibels to a tolerable level. The intake speed is also increased without moving parts to 1to3 times exhaust gas speed. Internal design prevents the oscillating gas from making an exit other than Exhaust! adding efficiency

Man I can only hope that vise is tight.

Bring on the pulsejet orchestra!

Sounds Like a Titan Engine starting up

chillin out max and relaxin out cool

The size and frequency are intriguing, but what about thrust? Can we get some thrust measurements?

Wow! Cute little design! How much thrust?

This project is very cool anyhow! I would like to see a Hydrogen Peroxide engine like the old military torpedos.

They generally don't generate much thrust despite the noise; They aren't very efficient... but I wish they measured it because I'm curious too.

what did you use to spark the spark plug?

super video!

Please tell me. For gas do you need any atomizer or injector inside the engine? Or just a regular pipe takes the gas?

Hunter In a tank, acteylene is not it in its liquid state. In fact, it is dissolved in acetone.

What is the blue cloud you can see on the gas tube (upper part)

how much thrust does the engine produce?

How did you make the sparkplug fire by hand ?

So, how much thrust does this produce?

aw, so cute...

Hi I want to do one of these for a science fair project, I was wondering what did you use for fuel, and what did you hook your spark plug up to for power?

do you have a link to a video that shows how you can make this?

Awesome! Now you just need a smaller, lighter spark plug and a titanium tube. You would have a hell of a thrust to weight ratio.

is a generic grill ignitor you can find them at menards

What would the ratio be between the size of the combustion chamber and the size of the exhaust pipe be, and the ratio between the combustion chamber and the intake pipe be?

How do you know the frequency that it is resonating at?

Very Good!...

Woah hey same here. I would really like to meet someone with the same plans!

The interesting question would be what levels of thrust were you getting from it. The fact that it runs at 1200 Hz is neither here not there if it only produces the thrust of a sneezing gerbil.

clever,so the right frequency sets it off ? hows it work ?

my weird ass actually searched for this

How much grams is the. Trust of the engine?

I love these, they would really piss the neighbours off

Did you used va?

@13bROT8N With an ignition coil, an condensator , 12 Volt Batery and an switch. Everytime you open the circuit it makes an spark.

now this would make a great hover

is that flame coming out of the intake pipe where the gas goes in? and if yes, isn't that dangerous?

do you have the design/plans for it still? I know this video is really old, but I think its extremely cool :) I want to try and replicate something similar lol

@sassobasso

Did you made it? i want to replicate it

Its a wierd process but surorisingly simple. Once you light the fuel and air it expands down the tube, decreasig the pressure in the combustion chamber. Then when the gasses are expelled out of the tube, air is rapidly sucked back into the chamber and the residual heat re-ignites it. All this happening over a 1000 times a second

tell me, os the intake bigger or smaller in diameter than the thrust pipe?

what thrust has it?

cool!how much thrust?

Also possibly from, a tach on the spark

how much propain are you using?

how much power would this have? like in pounds of push?

Very cool indeed

did you shorten the intake and exhaust?

Does it produce any thrust ????

they can create some useful thrust, the german v1 flying bomb was powered by an pulsejet.

mig welded?

How are you measuring the frequency? PS I am too lazy to read all the comments.

holy hell thats loud!!!

i want to make one but how do you get the spark plug to spark?? can neone help

Sweet! A pulsejet Hair dryer, lol!

do you run air into it constantly? could you use a fan for compression? i guess you dont have an idea of thrust in lbs eh?

Producing thrust?

What if you make it WITHOUT intake tube? I say the intake be the exhaust tube. Pardon mi poor English.

thrust?

Whats the THRUST at 125mm?

Do you have the measurements? I've built large ones but would like to make a much smaller version. - Thanks!

can you build me one(valveless pulsed engine and how much?

How much thrust can It give?

Someone should make a pulse jet organ. But how to make it start instantly when a key is pressed?

ha, it sounds like a die grinder you should power an rc car with it

propane powered fire whistle

good ! but now can they hear a whistling train coming at six feet away?

why arent these available to buy online for under $50

that a hella high pitch pulse jet

noisy torch.. you neighbors like you every time you turn that thing on :P

why would you set up the camera then stand in front of it?

Sounds like you're beating a dachshund to death!

I like the biological ignition system!

@elchicoboy looks? :D

its an engine, although it would be used in missles i would think....

@euklid216 lol exactly!

my dentist has one of this

Very interesting. The pulsecombustion.com website in the video appears to be gone.

i have the same question but id like to follow it up with what the hell is the point in everyone building these things....what the hell are you gonna do with em....or are you just buildin them to have something to do...i want one and dont know why..

hola y para que sirve esto. no comprendo . saludos ... argentina..

what is the smallest valveless engine that you think i can manage to run on propane. I need a very small engine to power a rotary rectifier for public demonstrations. If you can provide length and inside diameter, that would be awesome. I need one with front intake.

@carbon1255

+ifocoeur desir well I imagine the jam jar design is the smallest and simplest. Also no valveless jet engine has a front intake, all holes provide thrust. Valveless are also inappropriate for providing rotary power, basically useless in that regard.

@ 1200hz thats a noisy little bugger!

by any chance, do you have any rc cars? if u do, that + 1 + a video lots of people would probably watch.

if it has enough thrust you should rc it on something.e.g. pland,car....etc....

there is a type of pulse jet exactly like you say lol

jeah the GAS bottles on the Right :DDD

The self evident genius of this palm sized pulse jet is found in Santilli H+H+CO stochiometric carbon arc rod plasma generated fuel requiring water, immersed carbon arc rods, and 36v DC 40-50 amps. This elegant Solid State jet should be used in near closed-loop (having only fuel/air intake) Heat Pump, Powerplant, HVAC, Blast Furnace. Energy, steam, diamonds/rubies/saphires, diodes, hot water, anyone ?

(when the guy in the blue was in fron to the engine) with its screaming it sounds like the guy in the blue is passing wind (farted)

@maxinpains ?? what? Just a quick Google and Wikipedia shows "The French inventor Georges Marconnet patented his valveless pulsejet engine in 1908" And everyone knows Sir Frank whittle invented the Jet engine.

dont understand.. why he should block our sight/

looks like a sten gun.

Secondary exhaust I think. It's valveless, so it uses an "aerodynamic valve", a u bend as an intake. So thrust essentially comes out of 2 pipes. That's my take at least. Any other suggestions?

You can see the spark plug through the meatl! YO

Es una clase de reactor. Se utiliza como impulsor. Lo utilizó por primera vez con éxito la bomba v1 de los alemanes en la segunda guerra mundial pero el desarrollo viene de los años 20. Saludos.
