Try dumping nitromethane into it just make sure you’ve got a flash arrester in the line that stuff is pretty damn volatile when it burns it produces oxygen like NOS but the difference is nitromethane is combustible by itself and NOS isn’t
Good Job!! Test to failure indicates the awesome power of the venturi effect to deform the heated tail pipe. Also, very interesting the deformation of the pipe had a trefoil pattern. It may be that the pressure wave in the pipe actually has a trefoil symmetry. That is, the normal mode of the sound waves that are excited by the combustion and/or air intake manifold may have the same shape as the deformation. Maybe the frequency of that mode would match the sound you hear when operating it.
The sound vibrating your throat begins at 140 db but you cant swallow when you reach 153 db from his angle he was hearing around 153+db and at the back it might reach 160 db.
Was that the way the original V1 engine was valved? I always thought it was it was more of a set of hinged valves that went across the front of it. I was also curious if you were timing the ignition, or just maintaining a high frequency spark.
imagine if the gas turbine engine was just impossible to build due to the materials used to make blades, being not available. imagine instead 16 or 20 of these pulsejets used in the place of the gas turbine instead.
I like the part where it nearly comes of the stand and kills you :D What do you call those things holding it down? Come again? R-r-r ocks? Rocks? You should legally change your name to Capt. Robert Safetydox.
Wow, I was thinking that very same thing! (using nitrous). I would have thought that using nitrous would allow you to push more fuel through to get a more powerful blast thus more thrust and noise. I also wondered what it would do if you used just straight oxygen. Your results are really enlightening. Do you know what the chamber pressure is at max?
Is it just me, or does it sound like an echo of the engine around 1:33 min in film? If so , sound travels at 5 seconds a mile , the echo was 50 seconds from engine shut down which is 10 miles, so 5 miles out and 5 miles back....any large mountains around to reflect the sound........ I was listening to this with a set of headphones...... any comments?
Hey,
I did a bunch of testing with Nitrous, the engine would take a lot more fuel but would not make more thrust.

Mr Maddox, you are an inspiration!
I will get to it as soon as I can!

wild man! I love those engines. new bild as a presentation for oldfashioned simpel functional engines
Sir, I like your pulsejet engine and is really so good. can you add some jet fan too I think it will work more powerful?
This is epic
GREAT WORK DUDE ,KEEP IT UP ,SCIENCE IS FUN AND COOL
The scenery is just like parts of Australia............but wow the neighbours must really wonder what the hell is going on =)
That's epic!

You ever think of Giving one of these things a Boost with a Shot of Nitrous?

i can think of 2 or 3 different ways to use the explosive force of the engine in operation to be its own pump.
Lov it
素晴らしいパワーです
In fact I can almost hear it start around 1:14 and throttle up and down a little with the volume turned up!

Resonance problem ?

That was a distant Jake break the echo would of had bin longer since he ran it for 20 seconds.
Where do you get the read valves
What is the thrust on this puppy?
wild
Is this in Oregon
think it needs to be thicker look at what happened to the end of it 40 seconds in bent it
Great! I need one of those for when Jehova's witness comes for a visit
So 8 years later......Ive yet to see the "finished project" ?
You just bent the exterior of the engine
If you leave anymore religious stuff here I will block you.
deformataion :o
#OMG
