I love the long propane hose (for safety reasons), and then leave the tank right next to the jet.

That is not only a nice but also powerful looking pulsejet! You should mount that on a bike or a canoe

Heel goed en heel mooi ! The JT8D engines on the DC-9s, MDs and B-717 we flew required so many compressor stages. These pulsejets somehow manage to pull in (suck) enough air to keep the engine from Melting ........Dank je wel, tot ziens.

i bet the neighborhood loves you guys!

Great sound !

Обожаю этот звук 👍

Dude! That's awesome!

its an experimental engine, was developed back in the 40s by germany, in simple terms it detonates the fuel while regular engine just burn, it was thought that it could replace jet engines and turbofans, there being no moving parts and over all simpler, but they have been phased out by ramjets scramjets and most recently the SABRE engine

Tune it to about 7 Hz and it will drive people literally crazy.

a properly tuned pulsejet produces significantly more thrust than an exhaust pipe. they are less effective than a conventional jet engine but produce enough thrust to easily power a plane. In fact the V1 flying bomb weighing 5000 lbs,was powered by a pulsejet engine, which the German Luftwaffe fired around 100 per day at London in WWII

Were you able to measure thrust generated? Extreml;y cool, congratulations on the successful test run.

Bet your neighbours just love you ... :o) seriously though, a very fine project.

I landscape all day. i use my hoody for ear protection too.

I'd love to make one of those. Stainless steel, yes? I would consider adding fins along the length on the pipe to help disperse the heat.

@ChineseSweatShoppe This is the first test, its just running stationairy because we didnt want to flip the tank yet. We will let it run on fluid propellant shortly.

can u please , explain what is in the middle of combustion chamber,injector like thing.

In order to bend metal tubes like that, you need heat, and a bending tool. And for this tube, probably sand inside the tube to keep it from collapsing in on itself during the bending process.

I can in theory:::: a pulcejet is just an open pipe that works becouse of ITS SHAPE....... hehe Notice the kone shaped exaust pipe! as soon as the fuel explode, it blasts out the EASYEST WAY,, THE EXAUST KONE, and create vacum sucking in air at the other end, which mixes with the pressurised fuel coming from the gas tank and it explodes again in the ignitionchamber WHICH IS HOT, thats why they preheat it! It goes faster and faster, no valves,, just explosion-pressure-VACUM,,, thats why we hear B-R-R-R-R-R-R-R hehe

Klopt, éérste test. En op zich viel het geluid op een paar meter afstand wel mee, heel zwaar diep geluid. Maarjah hij draait alleen nog maar stationair :P volgende keer zetten we de propaan in een bak water om het bevriezen tegen te gaan, en word de gastoevoer groter.

oh i understand now, also could that mean you could use diesel as a fuel ? as it requires heat ?

@GAV63 Actually, it sounds EXACTLY like a V1 rocket, because it had the same type of engine ! The V2 had an alcohol fueled rocket engine, not a pulse jet engine.

I am so making toast with one of those!!!

I can see the spark plug not being connected to anything, so there is no spark-induced explosion, right? The motion direction of the combustion gas is directed at the beginning by the compressor. This is the valveless pulseless jet engine :)

@GAV63 Here's a great example of a working life-size replica of a V1 pulse jet engine : WCsKs2NhdWg (copy and paste in KZread search bar). The sound is therefor also exactly like the original V1's. Running idle on the ground the engine is less efficient than when it is flying high, at high speed. The air inlet speed and pressure is higher, the engine performs much better then, and also sounds a little bit different. The pulse rate goes up a little. Incredibly noisy machines, too, btw.

Looks like you're using propane, could you also add a little bit of compressed oxygen in with the mix and get a little bit more power?

@sjoerdbeukers yea, it is pretty weak, just giving you a hard time :D

Look up the German V1 . They used a version of the pulse jet during WW2 and they used them to attack England.

How much thrust does/did it have?

can I use it together with my bicycle?

Is zoiets moeilijk om te bouwen?

wats the thrust on this one?

Great!

Which is the intake aperture?

Thats ok I was a little upset but I am feeling better now thank you for being kind and apologising.

@GAV63 There are different types of pulse jets. The engine of the V1 was a straight tube and had no bent pipe. The V1's engine was more efficient then the type of engine shown in this picture. And no, it's next to impossible to get more energy out of this curved type of pulse jet. They all glow. Still, they are fairly efficient and were only used once. So the Germans never cared, as long as they hit the target.

You are crazy men!! but its awesome!

why is the spark plug not being used ?

How much thrust?

Pulse jets are very inefficient due to their low compression ratio (at most 1.2:1). In addition your resonator would have a very short lifetime due to extreme fatigue in the materials used- this problem also affects pulse jets themselves if they are of the valved type (the valves wear out very quickly). You'd be much better off burning the gas in an 4-stroke piston engine spinning a traditional A/C generator. If you really must use a pulse jet, be aware that the vast majority of the heat from your fuel is going straight out the exhaust of the jet without doing anything useful (I'd imagine that you would be lucky to get more than 5% thermal efficiency). You could recover more energy by using the heat coming off the jet and its exhaust to boil water and drive a steam engine than you could get from directly driving some kind of resonator or turbine, though obviously it would be best to do both.

@handleismyhandle

Unless you could develop a piezoelectric converter that could also make use of heat. . . Anyway, it's an interesting train of thought, somebody could make it work somehow, I'm sure. I just like the idea of a singing crystal making electric power I guess. Even 5% conversion would be pretty good around here where there is unlimited wood that is slowly oxidizing anyway. I reckon anything to be possible. Thanks for the input.

Question: Is the top part the exhaust, and the bottom the intake and combustion chamber?

@Max_Chooch

Fuel is being pumped into the larger combustion chamber from the propane cylinder and as you can see, he uses a compressed air tank to push air into the chamber to create an ideal fuel/air ratio. I see there is a spark plug attached but it appears he is using some other flammable medium to provide the ignition source. When the fuel/air mixture is ignited the shock wave from combustion blows out each end, but because one tube is longer, and one is shorter, the flame never leaves the longer tube. After combustion and the expansion of gasses has taken place there is a vacuum created inside the combustion chamber which pulls fresh air into the combustion chamber via the shorter tube, and because the flame never left the longer tube, it gets pulled back into the combustion chamber and re-lights the fresh mixture of fuel and air. This entire process happens extremely fast, many times a second.
