Sorry for this but there's a scam going on my comment section. I only use the email integza@gmail.com to contact the winners of the printers. Be careful! Do not transfer money to anyone, the printers are 100% free.
Ok thank you have you thought about getting a metal 3d printer for your projects they might hold up better than the resin ones
haha gotcha and I thought won something 😅 all good!
What's the telegram thing going on right now?
Ive spent half a day with this scammer. So do I still win the printer?
@@allen44p im not overly financially gifted and have a business idea id like to do in plastic
Hang on a minute, you're actually doing more backyard ballistics than I do!
What do you mean backyard. Haha
No, he is doing workshop ballistics.

Sounds like you need to tighten up then lol
@@Hackerisitic Nah, he's doing attic ballistic
As someone who spent 15 years in the reserves around jet engines, Integza needs to add ear protection to his personal protective equipment. I wasn't careful enough when I was his age, and now have the hearing loss to prove it. Nowadays you can get electronic ear protection that actually lets you hear quieter sounds than normal and only blocks sounds loud enough to damage your ears.
I lack your 15y being around jet engines, but I was thinking the exact same thing throughout the video :D For me....it was concerts. Now I have this lovely ringing.
@@AsmodeusMictian in the next 10 years we'll probably have a cure for tinnitus to be honest so its not too much of a big deal
Also important if you’re into shooting ranges
I built a shockwave jet engine. It was very loud. I needed to add ear protection to my personal protective equipment. The engine created a lot of thrust and was very powerful. It was an amazing experience.
Ayo, would you be able to link to the electronic protection you are speaking of? Would be awesome for my work.
You could create multiple combustion cylinders that converge into one exhaust pipe, something that looks similar to a Rolls Royce Derwent jet engine. I would combust them in rotation of a clock that way you will have higher pulse rates of combustion kinda like a radial piston engine.
only reason the ramjet isnt implemented more is the noise...
@@harleyme3163what? No, pure ramjet engines aren’t used because they create no thrust while stationary and thus require an assisted take off or something that serves the same purpose. Unless you’re talking about shock-ramjet engines which just aren’t practical for anything that isn’t supersonic 100% of the time.
Instead of electrical valves which would operate at a fixed frequency, you can try mechanical pin-activated valves that are activated when the pressure in the chamber is minimal. Thus, the valves would activate at the exact rate to resonate with the detonation cycles, like in an IC engine. Edit: Tomatoes are disgusting!
So basically a reevalve?
What is an IC engine? Also in what situations would you say electrical valves are more effective than mechanical pin valves in engines?
@@thed_ani The primary limitation of electrical valves, especially logic controlled, is response and repeat time. Integza is already pushing the practical limits for that in this video. The main benefits are the ability to activate at distance, and to activate on a particular schedule or frequency, within the practical limits as established. The only way to increase frequency in the case of this video would be to add more valve assemblies and fire them in sequence.
@@jono3952 Not " THE ONLY WAY " but yeah , one way
I just made a post on something similar however instead of the exact resonance frequency a 2/3 harmonic would likely be better as it would place the point of highest pressure at the exist of the exhaust.
Technically, this is a rocket engine, since it uses it's own oxidizer. Even cooler than a jet engine!
Its a rocket engine way slowed down, theirs a gradient between what we see as continuously and the amount of detonations, some rocket engines are measure in pulses, honestly I was hoping to see a v1 type of pulse engine with 2 valves, an exit to exhaust the pressure wave, and and entry one in the front sucking air due to the vacuum of the last pulse.
@@darkzide1178 you mean a ramjet, basically?
@@ThePinskinator Ramjet has no moving parts, a pulse jet has at least 1 moving valve, so no, not a ram jet.
I know these as Pulse Detonation Engines
@@darkzide1178 im aware of a fairly popular valveless pulse jet design. I don't think valves are a requirement.
thank you for being one of the only KZheadrs I can't understand on 2x speed ❤😂 you don't purposely extend your videos by talking slow and I love it bravo sir I applaud you
You could double your gas valve speed by putting two supply valves into the combustion chamber and set up your Arduino code to do an alternating trigger between the two valves.
Was thinking same thing ... although for 450 Hz he may need up to 45 valves per line (since he could do 10 Hz per valve ) at least I guess
Can you please explain bro why's there 4 relay? Two for valve one for High voltage generator and one more?...
Impressive tomato blaster, you should load it with a cherry tomato
Fascinating project! 👏😎
Aye margizmo!
If you are keeping the older builds, a video I'd love to see would be how they all compare to eachother in a proper and recorded testing session
The Shchelkin spiral spring was interesting how it improved the effect. I once tried a tall, curvy or ribbed brass candle holder one time where the "exhaust end" was very wide with not hardly any confinement yet it made a good bang just being misted with methanol and lit from the open narrow end with a Bic lighter. If you try that same trumpet shape with an aluminum baseball bat with the the ends cut off the flame front becomes terribly slow and won't produce a bang. But this narrow wide narrow repeating channel shape accelerates the combustion quite suddenly. If you turn up the volume you can get an idea of the sound from this video entitled Candlestick Holder with Methanol, maybe of interest and only just as an aside or tidbit.
Video Suggestion: Adding some sort of a nozzle to this would be interesting. The pressure is not irrelevant in jet or rocket engines. it is manipulated through forced expansion to increase velocity which does create huge amounts of thrust. perhaps a little known fact: the pressure at the end of a rocket nozzle is very close to zero. Ideally it would be zero but there are issues with being close and creating negative pressure that cause the bell to resonate and explode.
Exactly, adding a bell would also give a greater surface area for the expanding gasses reflecting off the slower air to push the engine forward.
This resonating is also the reason why there are different sized engine bells. With a smaller bell the pressure isn't that low, so it is better in an environment with higher air pressure.
I'd love to see a CNC'd rocket nozzle attached to this thing!
Maybe impossible but perhaps a cnc cone with reflection channels in the outer rim to not only take advantage of the expanding pressure zone in a more efficient way but if in the right area could smooth out some of the losses
To sum up the comments. PUT A FRICKING BELL NOZZLE ON THIS THING!!!
For the valves I would go for LPG injectors used in car engine LPG conversions. They should be able to open with required frequency still being relatively cheap.
I wonder if the exhaust can be funneled through a nozzle to further increase the momentum. The mushroom plume does not look particularly efficient.
RDE development is fascinating, im excited beyond measure that you're making one
10:46 NO FULL AUTO IN BUILDINGS
I just think that due to the engines rapidly heating up, it might be a good idea on the metal versions to add a heat shroud, such as on MG’s. This would help with cooling and allow you to conduct longer tests while reducing the possibility of overheating and issues associated with that. Just seems like it would be a nice quality of life fix.
you mean like on the lewis?
water cooling the thing would also give you a controllable meter. you could change the water flow rate and get different rates of cooling to keep the engine at the optimal temps for detonation. much like a gasoline engine.
"not a gun"
事实上你有没有想过，通过倒流部分气体出来到涡轮管冷端的气体温度可以降低到-40°，比用水冷跟散热罩好很多，并且所需要的气体量只需要很小就足够了
In order to conduct longer tests while reducing the possibility of overheating and issues associated with that, it is important to built a shockwave jet engine. The shockwave jet engine is designed to provide high-pressure air to the test area, which will allow for longer testing periods. Additionally, the shockwave jet engine will also help to cool the area, which will reduce the possibility of overheating and issues associated with that.
After seeing you try many many other engines, I feel like a video on a radial engine is deserved!
I look forward to seeing your rotating donation engine. I also look forward to seeing the previously unimagined engine I hope you eventually invent.
You have gained a ton of knowledge, tools, and expertise over the course of these videos. A theme for a future video that I would love, would be to see you tackle some of your earlier failures with with your new knowledge, to see if you can get things working!
Do you wonder why no neighbours complained aboud the 120dB noise? they probably all though Integza was trying new automatic weaponery. #10:43
Given everything else engine wise that you’ve created, I’m surprised I haven’t seen a video with a small scale version of the Orion concept rocket. You know, the one that was going to use nuclear warheads and a pusher plate to get into space? I guess consider this an idea for a future video if you haven’t already done something like this?
I'd love to see this engine with a nozzle/exhaust on the end. It would be interesting to see the difference between the non nozzled, a wide nozzle and a small nozzle.
A shockwave jet engine is a type of jet engine that uses a nozzle to create a shockwave. The shockwave helps to compress the air, making it more dense and thus more powerful. This type of engine is often used in racing applications, as it can provide a significant power boost. Building a shockwave jet engine is not overly difficult, but it does require some specialized knowledge and tools. The most important part of the process is choosing the right nozzle size. If the nozzle is too small, the engine will not be able to create enough power. If the nozzle is too large, the engine will be less efficient and may even stall. Once you have chosen an appropriate nozzle size, you can begin building your shockwave jet engine. The process is relatively simple and can be completed in a few hours.
A nozzle won't be need, it's too powerfull
So much yes! Pulse Detonation Engines are awesome. Thank you for this, on a side note I saw two different designs of air intake for pulse detonation engines that worked very well-one is like a powered air compressor piston assembly that as the piston goes up and down it pushes air and fuel into the exhaust tube (basically the exhaust pipe) and it acts like a backfire tune on a car. The second design utilizes a Tesla valve to allow one way transfer of the air/fuel mixture into the detonation tube.
6:14 you made a *_SCIENTIFIC MASS ACCELERATOR_* ... congratulations on your *_EDUCATIONAL_* achievement!
you can use three or more shockwave jet engine in order to have a rotation effect like a fan with a slight angle towerd the flower so you kan use the trust for it and from the fan rotation
Would love to see you try out making the rotating detonation engine!
I love that you take all these technologies that would seem impossible to do in your house, then.... you do them in your house lol. You inspire the shit out of me man!
Search for "Colin Furze" and "Robert Maddox". They build pulsejet-engines themselves and strapped them to all sorts of vehicles. Colin made a jet-bicycle. Enjoy.
This video also reminded me of the absolutely insane *Project Orion* . Which was a research project by NASA where they were trying to determine the feasibility of a spacecraft powered by nuclear bombs (they even built a scaled down version...that ran on conventional explosives of course. It effectively fired grenades behind it, these 'grenades' made a shockwave that then pushed on a thrust plate, which pushed the craft forward. A somewhat similar thing is happening to your pulsejet except instead of hitting a thrust plate, the dense stationary air is acting like a thrust plate.)
So sticky jumping in real life?
@@fragmissle5932 with nuclear bombs yes
@@fragmissle5932 Pretty much, but with the intention of scaling it up as far as a city-sized spacecraft basically 'putting a cup over' thermonuclear explosives and using enormous shock absorbers to turn the recoil of the cup getting slammed into the ship into a (somewhat) smoother propulsive force. Not the most efficient or safe type of engine, but VERY, VERY powerful, and _theoretically_ buildable with a fairly low level of technology (IIRC they developed a combination of steel and oil coating for the thrust plate/cup that should handle being repeatedly nuked at a certain distance surprisingly well, apparently).
@@05Matz the oil ends up protecting the steel extremely well, i think because of the leidenfrost effect
@@05Matz Yeah, IIRC the biggest concern was that considering how often it detonated, that would mean mass producing nuclear bombs in the millions.... Yeah... that's something to be concerned about. Don't get me wrong, they figured out how to do it and it's relatively easy. That's the concerning part.
Gotta love pulse detonation engines. Boeing had a design about 20 years ago, used dozens of pulsetubes like you created operating with an offset timing. They attached it to a tech demo stealth drone, looked like some kind of bird, stinking sweet.
Love ur content keep it up
Video idea: You should make a small Ion propulsion Engine!
But make it out of an air purifier.
Air purifiers that are 'ionic' are ozone generators. Ozone is a large component of smog. He could actually permanently hurt himself with that... If all precautions are taken, then it's a great idea!
@real So? It’s a concept engine, it’s not supposed to make any work or smth.
I'm a grad student running tests and writing my thesis on some RDE research! Excited to see what kind of work you are going to do with them!
Same
I’d love a 3d printer so I thought I’d suggest instead of oxygen why don’t you use electrolysis to generate your own hydrogen to burn in your rockets? It’s simple to do and it looks like you’d have most of the equipment to compress the hydrogen…. You can also use galvanised tubes for strength and 3D print the jet nozzles or machine carbon nozzles for the best thrust.
Oh, I cannot wait to see you do a rotating detonation engine!
Video suggestion: Making a radial engine, would be cool to have an engine with many sparks timed. I don't believe you have done that. I think they look so cool. Maybe even attach a propeller to make a moving machine
Video Suggestion: a VTOL (vertical take-off and landing) Jet powered 3D printed aircraft/plane. With maybe some kind of autopilot. I mean, something that with the power os some jet engines can vertical take-off and then switch to some kind of horizontal flight. Should be cool !!!
Your videos are great and you provide amazing content 🔥
This is the first video of yours I've watched. You've a different style than few other science geeks I follow. Not sure if I like it your style or don't but will try catch up with another few of your videos! Good work anyway, all the best.
Mano, os teu videos continuam a ser de melhor qualidade que os anteriores. É fascinante ver a evolução do teu canal, das tuas experiências, da qualidade do vídeo, da tua confiança! Fazes-nos todos portugueses orgulhosos! Admiro-te muito, Integza, e estou aqui para te ver crescer. Boa sorte, bro!
hey Integza. Love the video. I thought of using two cylinders to counteract one an other that would double pulses. further instead of opening and closing a solenoid you could make siphoning fuel source similar to a carberator but with an turbo compressor pushing air in and a reid valve to direct flow. also you could do different nozzle such as on traditional jet engines to further stabilize air flow. cant wait to see the next video! thanks, Ollie
I really enjoyed this video!
First time seeing integza without any failure Keep up the good work.
Judging by how loud that engine sounded in the video, may I suggest doing a video on making some DIY hearing protection.
Literally dangerous, you should NEVER skimp on protection.
tomato based hearing protections is key
Love the jet engine series! With all the comparisons between your pulse jet engine and a "projectile launcher," you should probably add ear protection to your PPE. It would be cool if you could do a video on custom molded ear protection or 3D printed ear protection based on a model of your ears.
Would love to see you try building a Radial engine! Like in an airplane!
Hey integza I was just putting a idea out there I seen your homemade gyrojet I was thinking of storing compressed steam to make a gu- I mean projectile launcher. I appreciate the opportunity to find a really fun and entertaining way to learn about jets, engines, chemical reactoins, and more keep up the good work and yeah, don't blow your self up
you could use multiple out of synchronisation engines so that there is always thrust coming out of the shock wave engine continuously .
I'd love to see you do one of those fancy multicycle piston engines. The ones where there's two cylinders that are normal four stroke, and then a third larger cylinder which recovers more energy from the waste gases. I don't remember what it's called.
Finally, a sponsor that actually makes a good product. I love onshape
You could also use a standard turbo for a rocket using compressed air and a fuel injection system and ignition with either a printed or milled nozzle. Try running the exhaust from the turbo back into the turbo with a fuel sprayer and ignition system? Once the compressed air gets it going redirect some of the exhaust back to the intake turbine a mixture of the exhaust and combustion should keep it going.
Please make a radial engine, I would love to see it!
yes
@@user-sb5kc9rb8c no
Instead of relays, you could potentially use a rotor + stator setup to time everything.
Was thinking the same. Like a hydraulic motor valve or a cam shaft. A stepper motor or BLDC are very easy to time. But any electric motor will work with Pwm
The limit is the valve itself. Inertia, momentum, and magnetic field strength, among other variables, finding their detent.
@@MadScientist267 I’d imagine the bottleneck would be the gas purge and mixing rather than a faster valve.
Love your videos! Looking forward to being able to do the same some day
Cooking up an RDE at home... This will be so awesome! It will be difficult, but a success would be more than rewarding.
PDE's are so cool! Love ur vids. Still sticking it out for an ultra-high bypass turbofan!
Using this engine, maybe using two valves in parallel and opening and closing them one after another, can maybe increase the speed at which the engine can run ?
thanks for the video
Love your videos, from trouble shooting hurtles to working the problem & success 👍😎😎
double or triple the engines to get continuous thrust, you need to time them so they will work in sequence, exhausting from single nozzle. similar to car engine. good luck.
the Nazis didn't need multiple engines and the doodlebugs lol
The logical conclusion of this is rotating detonation, which is like an infinite number of 'engines' in one detonation chamber.
Amazing how this engine is using the sound barrier (im assuming the difference in pressure) to push itself, like a person punching a wall to go forwards
You could pre-mix the fuel in a seperate box. Then make one connection to your actual chamber and break them with a ball valve. If you want to make it really fun, you could take out the blockade, that stops a normal opperator from overturning it and connect it to an electric motor. The faster the motor spins the more often your valve is open and the more pulses you can make
Love your content Integza:) and my eldest loves watching with me, you are an inspiration. Thank you.

Have you ever consider using topology optimization and A.i generative design tool for your next video ? 1 ) Generative design is a form of artificial intelligence that leverages the power of the cloud and machine learning while accelerating the entire design-to-make process. 2 ) It lets you use the full breadth of automation and machine intelligence to generate outcomes you didn't ever dream about 3 ) It's a great way to quickly prototype and iterate on ideas while getting feedback from the machine learning algorithms about what is and isn't working. 4 ) In the context of jet engine design, generative design could be used to quickly iterate on engine designs and find the most efficient design for a given set of constraints. 5) Topology optimization is a great way to design more efficient structures for 3D printing can be used to create prototypes of those structures quickly and easily. You can use it to find the optimal shape for a jet engine turbine blade. 6) You can use it to create a lattice structure that is optimized for strength and stiffness. 7) You can use it to create a honeycomb structure that is lightweight and has a high strength-to-weight ratio. 8) You can use it to create a variety of other structures that are optimized for different performance characteristics. I imagine that a jet engine designed with the help of A.i. would be incredibly efficient and powerful and would love to see you launch your neighborhood on the Moon with it =) Here some useful link if you are interested to try it : a)all3dp.com/2/fusion-360-generative-design-tutorial/ ( generative design ) b) www.autodesk.com/solutions/topology-optimization (topology optimization )
I don't know much about topology optimization but using generative design every day , I confirm it's a game changer !
@@coquelicotfingerblues2079 Topology optimization is also a game changer because it allows engineers to explore a much larger design space. With generative designs engineers (or self taught Makers like me )can quickly generate a wide variety of design options and then use topology optimisation to further optimize those options. This combination of tools provides a powerful way to explore and optimize complex designs.
You are awesome man waiting for your next video
Hey integza, an engine like this (pressure optimised) are best used as prop/shaft engines. It's much more efficient to extract the energy using a turbine rather than trying to push against the atmosphere
Hey Integza, great video! You always have interesting videos. Good to see you using eye protection. Along with that protection, definitely use hearing protection when doing this stuff!
Repeated Denonations without ear protection is probably not good on the ear drums.
@@kreynolds1123 Probably not good on the ear drums? Slight understatement lol, the sound from a PDE can be up to 171dB and the quietest they can be is still 100dB+ so even the quietest PDE can cause hearing damage after a few mins without hearing protection and the loudest ones at 171dB would very likely cause serious damage after just several seconds without protection
@@martinpeel1820 is it a kind of sarcastic humor in understatements?
Very interesting idea dude, can't wait to see what this becomes. Keep up the good work 🙂🙂🙂
Honestly this guy make a great tunner for cars !
I would love to see you create a video where you begin your decent into the rabbit hole of sound waves 🔊!
It always make me happy to see a new Integza video.
Hey integza, I've always wondered whether you could make a tip jet setup such as in a few helicopters with small versions of your pulse or other jet designs. You could either use two small jets, or one jet which feeds output to multiple angled tip outlets. Look at the hiller hornet. Amazing video as always!!!
Great job on wearing safety goggles! The next step would be to wear ear protection because bigger explosions == bigger noises.
Pretty sure I saw him using earplugs. Proper ones are just as effective as over the ear ear pro.
@@giin97 What do you reckon the odds are those are proper ones?
Have tried using mesh like the Saturn 5 rockets to even out the combustion? Excellent video
That's really impressive! You should try mounting one of you best motors on a car or a plane, or could be nice!
Nothing more exciting than waking up and seeing a notification for Integza. Love your work. Keep it up you are such an inspiration.
Love the videos you make
I'm a big fan of your videos and like learning new things. I have a good mechanical background and would love to start making things with a 3D printer. Thank you.
Also Ingegza, please, man, put on a full-face shield when standing around resin 3d printed parts that may explode. Eyepro isn't enough to prevent facial injuries. ;)
VIDEO SUGGESTION: It would be very entertaining and informal to make a combination of two pulse-jet engines in one machine that alternate their detonations so to provide a constant level of thrust. I'd be curious to see you create a twin of this engine and combine/program the two with a delay in pulses to oppose each other's explosion all contained inside one unit. 2 combustion chambers maybe? When engine 1 fires, engine 2 would be refueling and resting. Once engine 1 completes its pulse/detonation, engine 2 would fire and engine 1 would rest and refuel. 🚀 Get the timing right and you might just create your own variant of an "alternating" pulse-jet engine that overcomes one of the problems of pulsed thrust engines and their inability to maintain a constant force of thrust. I love your videos and the personality you throw into each one. Regardless of the content I always smile when I see one of your new videos and fun projects. Stay awesome and thanks for sharing your informational and exciting explorations with the world. I'd love to be able to dabble in the likes of your fun projects but until then I will continue to live through your excitement and adventure 😆 Stay well friend! I'll be looking out for the next one!!

really love your videos you explain things in a good and fun way. i was going threw your video's maybe a idea but i came accros this video to 3d print ball bearings maybe you could take a look at it and can use it in next video or so.
I would love to see you try to miniaturize this more and see if you can actually make something fly using this! Even if you can't get it to fly it'd be really freaking cool to see this mobile the rail is cool and a small train powered by jet engine would be awesome!
Idea for a future video: Since you use compressed air so often in your videos it’d be cool to make a 3D printed air compressor. You could use it to test out some other things you’ve built that require compressed air. It could be electric powered or for a bit more of an Integza style video you could use a gas turbine.
Yeah this would definitely be a good one
while it would be a fun idea, trying to build your own pressure vessels with a 3d printer is absurdly dangerous and the possibility of a catastrophic failure is very very high.
@@DuriensBane print hollow volumes to be stuffed with glass fibre matt then resin?
@@stevecummins324 it wouldnt be the container itself, it would be at the interface of the vessel and the connection that would be the weak point. Im reading now that you can have carbon fiber vessels but i would almost 100% assume that the connections are either brass/stainless/carbon steel in some form. Which would severly limit the viability of 3d printing. I dont see an issue with making an air pump, but a compressor is a different animal.
@@DuriensBane True. Perhaps just the pump or compressor assembly etc. rather than the the pressure vessel. Might reduce the danger factor and anyway this guy builds jet engines in his garage sometimes without eye protection and awfully close to high-rpm blades so a lil bit of danger if handled well wouldn’t be out of the ordinary.
super om te zien ik kan zulke dingen wel in mijn les gebruiken ik ben zelf docent op een praktijk school dit is echt gaaf
thats so cool !
Hey integza, love the video, how about you start working towards a full project from the beginning, a plane for example, you build the engine, the landing gear ...
I personally use onshape and its really useful. I designed an electrical demo board with it.
Hey integza, maybe for your next project try integrating the fuel/oxidizer injector of a pulse jet with a much shorter pipe, then add in a ramjet-style compressor. might help make th system more compact.
thats one kool engine imagine the possibility a jet with agility kool
Dear Mr. Integza, I’ve been watching your videos for quite some time, and they are amazing! I have been watching a lot of videos on sound and how sound waves affect salt on a flat plane. I was wondering is there any way of making a Sound engine or sound turbine? This is really fascinated me especially since a lot of scientists have been recovering data on crop circles that have a frequency that is left behind.
I'd love to see a destination engines performance underwater. I bet the shockwave would be phenomenal.
contue i love this series
You should try and try to build/install one of your shockwave engines or pulse engines to propel you up a drive way or a ramp/hill
make a nozzle cooled by the fule of the engine, it should prevent overheating, i think
nice
