It looks like the Dyson hairdryer (which uses the same effect), though I'm sure this one would dry hair much more quickly...
Hell yeah, it'll dry the hair right off your head. Lol
Hair fryer
@@AlphaCharlieFour bruh
Can't have wet hair if you have no hair
oh for sure, but i feel like there would be some,,, unplanned side effects, like burns perhaps
I'm not sure about the jet-engine thing, but it would definitely sell as a hair dryer. Just avoid the "satisfied or money back" scheme...
im sure you mean hair fryer
This idea has already and still being done and sold by Dyson. Any attempt of selling this would mean counterfeiting and getting sued lol 😆

@@OdysseyABMS you seem to have missed the 'lol' at the end of my comment...
@@5oglock474 that one spit hot air this one spit fire
In all fairness, Dyson does not refer to their product as a “fan”, but as an “air multiplier”…which is exactly what it is/does.
They did explicitly express "no fan" both txt and imply, in many commercials and still do.

Average fan vs average air multiplier
@@arnoldswaggerson6938 AHAHAHAHAHA
maybe just one day or something like it would work better than that but we could get the same thing for him and you guys are going on to the house in about an hr or something and they don't know how long 😂
I recommend getting some upgrades for your filament printer specifically for high temperature builds , some parts that are polymers of more than one material have some pretty impressive material properties one good example is carbon fiber nylon which boasts a high resistance to both heat and stress nearly on par with some weaker metals like aluminum, I've been using it after electroplating it in industrial uses for the last couple years with some impressive results given it only required some relatively simple modifications to my existing ender series printer , I personally invested in a filament heater , Heated bed and glass as to prevent bed adhesion and a full metal hot end and tubing as a bear minimum to start dabbling with some of the more hardcore filaments out there and I've had no regrets , some learning curves sure but it opens up a whole world of applications that traditional filaments and 3d printing just could never hope to achieve due to one material property or another
Next video idea related to this one, (this time explained well for real)
Have a line that goes through the impacted areas of the plastic piece, to where a liquid that in this case can be water, as we don't care about weight like somone suggested, and have it flow, that then comes out of the other side of the and goes into a radiator that cools off the water again and re flows it inside, to have an infinite loop of cold water that will prevent the heat to melt the plastic.
It's a good idea but quite over engineered imo, it would take quite a bit to make, but what's not over engineered in this channel 😂
@@rombularengine5279 some rockets engines and probably jet engines use a similar concept, but instead of extra weight for a coolant such as water, they just pass the liquid fuel itself which doesn't have an oxidizer around the combustion chamber in small tubes, I believe this is called regenerative cooling.
@@2k7u yea that would make sense but image if a little bit of the plastic melts and penetrates inside the line of fuel 😅
@@notscar Well, guess that's pretty much where the limits of this plastic is. It's not a material meant for surviving such a large amount of heat, maybe thermoplastics would do slightly better, but honestly I would much prefer to see this channel start making metallic designs
YOUR PFP!!! THAT SYMBOL AGAIN!!
Video Idea: Try to create a version where the fuel is injected directly in the resin part. this way you can have many small channels that act as a nebulizer, potentially with a better fuel too and the best oxidizer available. Then you could try it in the real world on a RC plane, maybe in collaboration with FliteTest. (right now they are making some pretty cool Star wars pod racers that would really fit this innovative motor).
By the way, I really appreciate you making informative and fun videos linked to 3d printing, rocketry and new ideas. It's really inspiring!
Also Tomatoes are disgusting!
This comment must be the winner.
@@prof.tahseen6104 thanks! I think the idea is good and especially fun. Maybe the pilot can be a tomato too, like this if everything explodes integza will be happy
yup 100% winner
Yes, just yes
Gotta route the liquid propane around the combustion chamber to help cool the parts too. That should cool the parts, preheat the fuel, and there'll no more mucking about with brass tubes.
How about change the combustion point to see if it makes a difference in the heat transfer. Also how about measuring the air flow vs the fuel to make sure it has a good ratio for complete combustion.
7:50 that was beautiful! Didn't expect anything close. Good job and best of luck for better future prototypes.
I saw you had some repeated issues with "flame-outs" when the air velocity got too high and basically blew the flame front out the exhaust. In jet engines, they have similar issues, and deal with it using a simple structure known as a "flame holder", which is just a small baffle that keeps some combustion going in its wake turbulence. Worth a try.
9:09 you should use polysulfone, polyphenylsulfone (Radel), or polyetherimide (ultem) for that translucent tubing. Those materials are actually meant to be used at high temperatures, unlike acrylic. Siraya Sculpt Ultra resin will hold up to higher temperatures too.
I love this comment. Answers like this could lead to the next bit of amazing content from Integza!
Good idea but even polysulfone heat resistance isn't anywhere near the temp of burning butane or propane, if using plastic for the top I think the best option although tedious, is to try to add water cooling channels throughout the plastic
@@julianburr1832 I was wondering about this

Hello Integza, I know you only since December, but I really like your videos. You should try to create a fan-less turbine but with the explosion chamber in between two Dyson fans, in this way you can use even better materials to make the chamber
Good advice!!
Blu number one
Clever, Smart, and funny. You’re great Blu!
Very interesting 👍🏻
Ok
I think it would be cool to see integza make an actual rocket. Considering that he already has a lot of examples of working propulsion systems, it would be pretty interesting to see it in practice.
Edit: Welp, I lost :p, but thanks for all the likes.
Well, working might be a bit of an overstatment...
@@markinipannini Sugar rockets should not be impossible for him since he has so much experience already
He has made several working rockets, usually they are on sleds or skateboards.
Well, he probably does have enough experience but I don’t think he has the budget, equipment or materials to do it.
@@camhollo1139 He can make engines, he can probably rob a bank. It's not that hard...
That was brilliant, beautiful material science in action!
Bro, i love that you're doing this in your freaking living room with your computer and monitor setup BEHIND THE JET ENGINE.
I really would like to see you build a coil gun , not a classic one, but one structured in a loop, like a particle accelerator. Probably the "bullet" would reach much higher speeds. I guess it would be perfect to smash some tomatoes, by the way 😂
That would ve SUPER dangerous, since youd continously accelerate the bullet untill your accelerting force is the same as the friction, so it could reach insane speeds and tear itself apart.
Also it probably wouldn't work, because Railguns are typicaly run on capacitors, wich works great, since you dont need a continuos power output, but only a very short one. But on a circular accelerator you'd need a continuos powersupply, with absolutely insane Wattage.
Good sir, this is a cool gun, not a railgun
A railgun would be so cool!
If are using a coilgun or linear gun instead of a railgun, should be able to accelerate continuously.
@@niemanddings9517 okay so I agree with your point, it's an absolutely stupid idea due to the amount of danger involved, but using more capacitors and discharging them a bit more slowly, while also using a smaller projectile should work. In my mind it just looks an insanely dangerous hot wheels track or something. (Also the more i think of it the more dangerous it seems.)
Hi Integza, I believe having combustion inside the loop will be more effective and produce more thrust. Although you still have to find out a solution for the loop to withstand heat. I’d suggest you to try it with metal filament you showed in Aerospike nozzle video
thats a too complicated geometry for a that complex type of filament, he would have spoke about it if possible
@@__razor__ i agree with your point. But I guess making the loop bigger might make it less intricate during printing and processing.
Line the inside with starlite?
Hi! Great video! I think that the white flame may actually be from the polycarbonate burning. A cool addition would be a infrared camera to analyze how heat distribution could lead to improved performance.
I don’t really have a suggestion for a future video but I have just found out channel and loving it. I have been binging all day
Me: *reads title*
Also me: "of course you did"
Nice one man!

It may be worth it to design cooling channels into the walls, hook up a small water pump and make it liquid cooled similar to some rocket nozzles.
I love your videos! Keep up the cool work!
Wouldn’t that condense the exhaust gas making the engine less efficient?
Maybe but a engine that shatters itself isn’t terribly efficient.
@@Mourningstar-kc7ft you got me there
The geometry of the inside could remain the same. I was thinking the channels could be part of the walls like the F1 engine or other similar rocket engines.
10:14 Plasterer here, there are other plaster mixes that are far more sturdy than quick dry varieties, which would indeed be really weak. Keene's Cement should work pretty well as it's very durable and hard. Awesome video!
Couple of things I am seeing… 1)you have a fuel starvation issue at the highest speeds. 2) it seems like a lot of the energy from combustion is acting perpendicular to the axis of thrust you want, try to move the injectors so they are internal to the “fan” part rather then the impeller. If not the injectors, then maybe an ignition system so you can measure the air/fuel ratio in the up-tube and get an optimal combustion ratio for a given airflow. This will also mix the air/fuel more, allowing for more efficient combustion . 3). You will probably need to use either a hear resistant ceramic like you tried, or use a metal that can withstand high temps for your initial tests. (Option 2, run a coolest loop around the housing and a cryogenic fuel similar to a rocket bell). What you did was amazing, so don’t give up on it. I think you are close. One other thing…have you thought about applying fuel to the airstream coming though the center of the engine and igniting that somehow as well? Good luck
How can I contact you to talk about some “ideas”?
Video Idea: Try to make a hydrogen powered rocket
Like, a usual rocket?
I almost died making one don’t do it it explodes violently
Maybe such that gets the hydrogen from a hyrdrogen generator (car battery or such, some electrolyte, water and metal sheets) - you'd get the perfect oxygen to hydrogen ratio automatically since the burnable gas is generated from a burning product of hydrogen (water) - a simple blowback valve/ a few of them should make it decently safe too
He should also make a 20‘ x 5‘ airship with hydrogen hehe
Electricity would be better
Video suggestion: try using heat-resistant resin! We use it often in my lab and it's able to sustain about 250°C and pressure up to 0.45 MPa. It might help with this prototype! 😁
I would assume the temps are going well above 250C
They might be close to 500C
@@IIGrayfoxII a sustained flame would heat the part to well above 1000C.
@@Rudy97 Was thinking 1000C, similar to what a real turbo or jet engine would do.
But turbos and jet engines get ideal fuel ratios and have been engineered to get to an ideal temp.
A home thing will run less efficiently.
@John Thomas Well, this guy sort of remade it th-cam.com/video/0IbWampaEcM/w-d-xo.html
And by his explanation, it wouldn't work in this case, because the material expands.
@John Thomas Starlight (or other more modern intumescent materials) wouldn't be a great option, the expanding carbon foam that makes them work is going to block airflow. Check out Nighthawk in Light's series on it.
On your next jet engine you should make it have a bypass air system to cool the engine like on a turbojet engine. Air flows through the outside case to help cool the engine.
First video I have seen from you. Interesting and fun so I subbed. Looking forward to more!
For ignition, you should look into glow plugs. They're DESIGN to ignite fuel. They stay on, and you can use a less complicated power source. They're a pretty cool, basic technology that work very well.
They are not designed to ignite fuel. They are designed to heat up the cylinders in a Diesel engine to help the diesel fuel burn. They do not stay on either, they will turn off after a few seconds and in modern diesels they will come on and off while the engine is running to help it be more economical. Spark plugs ignite petroleum fuel but they also don’t stay on.
@@Alexander_l322 I believe he's referring to r/c glow plugs which do provide ignition for nitro based fuels. They don't run on the diesel cycle, they're traditional two strokes. The glow plugs although not powered the whole time do retain heat from the previous combustion cycle to ignite the fresh air fuel charge.
He used some in a past video so he might have some
@@Alexander_l322 They arent designed to heat up the cylinders per say they are really more analogous to spark plugs because they are the source of energy that allows for the detonation to take place when otherwise it wouldn't like when the engine is cold during start up. So its a starting aid in diesels that provides the small nudge that is needed to allow for the proper conditions for detonation to occur. When cold the cold engine block can absorb the heat from compession and not allow it to ignite but once it does they turn off. Now if your talking about R/C glow plugs on engnes using nitromethane then the key factor is that they have a platinum catalyst which when heated up to start catalyses the nitro to ignite and creates heat that continues to ignite during each stroke, Its self sustaining so doesnt require external electrical or anything to keep it going and is somewhat self governing/ timing since as rpms increase it gets hotter which intern ignites faster.
Regardless, glow plugs rely on combustion of pressurizing fuel in the cylinder
As the nozzle of your experiments always comes out on fire, it would be interesting to try a cooling system that uses the fuel itself (or water), as real rockets do. It could consist of leaving some tubes inside the walls of the nozzle and making the fuel pass through it before going out to the combustion chamber.
Yup! man uses no cooling at all. That's why he's always burning his mustache.
@@cmwgfo2024 Well, maybe it's true that a lot of chamber pressure is needed from, but we could also say that to create a nozzle you have to use very high quality materials, and integza does it with PLA and other 3d printing materials, I think he's capable of make a cooling system that work for the nozzle... at least for some minutes XD.
I loved to see this project completed!
Very cool! Have you thought of using heat resistant engine paint? Some brands claim to resist up to 2,000 degrees Fahrenheit, you could easily apply a few coats to the surfaces exposed to high temps. You may need a primer or something to bond the paint to the engine to maximize integrity
The paint would probably only add a couple of extra seconds until the plastic softens and melts at which point you basically have a fragile fluid filled bag rather than just the fluid which is pretty much the same thing when using it to shape the flow of a pressurized gas
Hey, love your videos! It seems that all your projects fail because of the generated heat. You know what would help? Aluminum ! As you already have a kiln, and have some experience with molds - try aluminum casting. This should definitely help to get some progress with your projects.
aluminum is less heat resistant than the resin he is using. that should put into perspective how hot the engine gets
I would say steel melding is the best. Go heavy metal.
@@sakarrc5001 or you can compromise and use titanium... Not as strong as steel or as light as aluminum, but it's lighter than steel and stronger than aluminum
If you want REAL heavy metal though, go with inconel x, the same material used for the X-15 space plane, which set a record speed of about Mach 7... Inconel X is extremely heat resistant...
Suggestion... Use the impeller to compress air, inject fuel through the front, burn out the back. Basically build an afterburner. For heat you could line the inside of the combustion chamber with aluminum ducting tape and build in piping for water cooling.
while that could work but it is not the heat in the combustion chamber that he his having a problem with but what i think is that the fan head is not designed for high flow but smooth low flow to take full effect of the viscosity transferred to pull air as we don't need the jet equivalent of air in our normal fans so i propose a new head that will work with the high flow as it seems that it produces some back pressure in its current shape
@@stuartpratt3662 Interesting. Are you suggesting something like a ramjet, but using the high pressure air from the impeller to drive it without needing for it to be moving at high speed? If that could work, it might allow for ramjets to take off on their own without needing a conventional jet engine. I like it.
I would love to see a jet attached to a remote controlled car. Maybe even get the car to fly if enough thrust can be produced.
you can protect the build using refractory material or simply clay. but you should allow it to dry real well before applying heat.
Hello Integza, as a concept for a future video, you could make a turbine based on Vortex Induced Vibrations.
Tomatoes are disgusting!!
I like tomatoes. By the way i agree
A bright white is a sign of nitromethane. The 'nitro', likely, is coming from the decomposition of the resin. So not only is the flame burning the resin, the fuel is likely reacting with the resin as well, before also burning.
Try adding a chunk of resin to some of the fuel in a container and see if they react. Can't really use materials that react with the fuel being burned :)
Basically, even if you can't find a plastic that is completely heat resistant, if you can find one that at least doesn't react with the fuel, you will be MUCH better off.
Would somehow coating resin help as a heat shield maybe? Similiar to dipping parts in paint, or similiar to Cerakote.
It DID look like a Nitro flame..
I’m way behind on the timeline of this subject but will try to catch up. I just found your videos and subscribed! Your videos are great and inspiring! There are so many things I’ve wanted to design and research over the years and was beginning to lose hope. Now I’m excited again! I’ve been researching jet engines to see if I could build one and how small could I build a working one, with the RC models in mind. I’ll keep watching to see this develop.
Granted you'd have to purchase them but for heat stability try using black pipe and fittings to create the housing for the coanda effect. It will probably also increase ignition efficiency due to the absorption of heat, but need a way to keep it from melting your acrylic. The fan seems to be able to keep the heat away from the impeller so no worries there
@@integza1.. responding to winner notification?
Loving the concept of a Jet Engine with the Dyson Fan design. I think your Air / Fuel Ratio is getting messed up when all the extra air gets drawn in. Try leaving the motor where it is and moving your fuel manifold and ignition to the location where the air exits. Like an Afterburner on the F-14 Tom Cat. And print your air chambers in such a way that after leaving the compress and being funneled to the housing with vanes to creat a vortex. Then your Flame would only effect the tail end. And print the end out of ceramic. Now everything would only have cool air on the acrylic parts.
I think that would work and prevent the flameout, but it also won't produce that much thrust, I *think*.
A jet engine produces thrust by accelerating a large mass of air, which is done by combustion - you burn the fuel and it's basically exploding out the back. It has to happen early inside this model, so that it can expand through the air multiplier section on top, and then get the benefit of entraining air from the outside. So there's no way to avoid having to deal with hot gases inside the thing.
You definitely could move the fuel injection to the late stage as suggested, and it would then be afterburning. The catch is that afterburners are notoriously fuel inefficient, but they do objectively help produce more thrust if that's what you need (in a military plane anyway). An afterburner may also require a nozzle to be effective, I'm not sure on that part (the outgoing air needs something to push against so it produces thrust force). Operating in the air-multiplied stream without a nozzle may just do that for you if the pressure is high enough, I have no idea 😂
Have you ever considered casting your prints in aluminum? I know it's super involved but also will give you relatively strong and heat resistant prints
A funnel hopper for aluminum cans that correctly orients the cans in the correct position to feed into a lever activated can crusher. The lever can be operated by hand or by pneumatic force. Okay, solenoid or motor with cam can work, too.
Jetoptera has a jet driven impeller that pulls in air that is mixed with the exhaust and ducted to the Dyson nozzles. They dont have 2-4 engines to match their nozzle count for exactly the reason your experiments showed, heat damage and fatigue. If you could mix in colder air with the exhaust, you could achieve similar results as Jetoptera.
Once you've concluded tests with this, I'd love to see if it can be scaled down to make like a jet powered drone. That would be sick.
Wow!! Yeah, its all about the heat control.
Sounds so cool but sounds dangerous at the same time
But it's marketed as a bladeless fan?...
@@MrPotnooble bladeless jet engine, maybe. Heatless jet engine, no.
You wont really get more thrust than the straight fan. Back pressure from the expanding gas pushes back against the fan restricting airflow. this also makes it really hard to get a stable flame front.
1:25 6:55 You're thinking of Bernoulli's principle: the high-pressure air, when shot out of the fan, becomes fast velocity air. Very fast air means lower pressure since the air rapidly leaves the area it was passing, leaving empty spaces. This low pressure causes surrounding low-velocity higher-pressure air to rush in and fill the space, in the direction of your face
I'm this case, the principle is the coanda effect, in which moving air drags the air around it along with it.
@@IronBand4 coanda effect would be the sticking of air onto surfaces, especially curved ones. Interestingly it's also to do with bernoulli's principle! The fast moving air causes low pressure. Normally this drags surrounding air into the fast moving air stream (since the surrounding air is higher pressure, it gets pushed towards the low pressure stream), but when one side of the stream is a solid surface, then the low pressure sucks that fast moving stream towards the surface, while the other exposed side of the stream has higher pressure ambient air pushing into the steam towards the surface.
@@Yadobler exactly what is happening here. The slot is at the back of the cylinder and the air travels along the annular airfoil to the trailing edge, dragging the ambient static air with it.
@@IronBand4 Same concept to inflate emergency slides on commercial aircraft.
This video earned my subscirption. Great work!
For a clear, heat-resistant combustion chamber, see if you can source a wide tube of borosilicate glass. It doesn't expand/contract as much as regular glass with changes in temperature, so it's less prone to shattering while heating up and cooling down. It's used in proper laboratory glassware, so if you can't find a borosilicate tube, perhaps find a graduated cylinder or beaker made of borosilicate glass and cut off the bottom and top
Make a super efficient jet engine, like a general electric newest engine
yupp
yes i would love it
Hey Integza,
I was wondering, how about keeping the system like a dyson fan but instead of burning the fuel inside the chamber, why not use it to deliver the air and fuel mixture to the ends of the bladeless fan and igniting the mixture at the point where currently the white exhaust is coming from. Just like an afterburner sort of a thing. This way you can keep the 3D printed parts cool and still use it to combust fuel and air.
You’d still need a nozzle to direct the expanding gas and make meaningful thrust out of the engine.
yeah igniting gas after it has left the engine will not do anything. You would need something to extract the energy released from combustion
@@BharathwajSathishkumar see that’s what I am trying to say. Imagine the same setup shown in this video, but instead of having an igniter inside the fuel chamber, we let the mixture of fuel and air pass through the setup but modify the exhaust end a bit and add multiple igniters of a different type to ignite this amazing air and fuel mixture. Basically the exhaust end needs to be modified.
@@NAYI94 not igniting it after leaving the engine, instead igniting it just before it leaves the engine, i.e. at the exhaust ends
I think afterburners are a way to get extra thrust, but not very fuel efficient.
You are an AWESOME inspiration. I am keen on getting a 3D printer myself and see it for myself,what your work was.
You can turn the vertical fire tube, to horizontal and align that fire straight into the exhaust. That way,you can use the design you made before without the geometry changes,you were planning to do. For air intake,you can bleed air in, through the sides.
Heads up a printer has a big learning curve
I love your unfounded optimisim. If you bend fire around plastic surfaces....
Anyway a mate and I were talking about using an underwater version to bladlessly cycle a fish tank. The bet was would they jump in to the loop just for the fun.
Hey Integza, they make brushable ceramic epoxies for high heat applications. A bit expensive, but if you painted that over a printed part it might make it last a lot longer.
If he tries it and it ends up working well then I feel like there are several projects he could revisit. The lack of good heat resistant materials is like a theme of this channel
@@-Kerstin 3d printed metal would work too but I'm sure it would be even more expensive then the resin
That's how they harden the edge of Katanas and leave the spine flexible, ceramic paint wouldn't be to bad an idea. Or alternitively use a clay wash, similar to how mud dries on an object.
@@elliotcutliff7779 I guess in modern times they would use that but more traditionally it was clay
@@jakobfindlay4136 Yea that's what I meant but I'm bad at explaining, Damn muddled brain. lol
You're attempts at creating a part that was heat resistant were interesting. A video showing the different/best ways of creating parts from plaster, foundry metals would be very interesting.
depending on the temperature that occurs in this design, casting aluminium with lost pla method might be worth a shot...
Very nice. I love my Elegoo Saturn. Beast of a machine.
Do you know the trick where you boil water over an open flame in a plastic bottle? The water can't exceed 100°C until it's completely evaporated and the plastic bottle doesn't melt for an impressive amount of time. You could print the part as a hollow shell in resin or pla and fill it with water, might be interesting to see/ a viable way to keep the parts from melting
Thats happening in the car
Amazing! Let's just apreciate how much work this guy have put into it every one of those 3d prints are a major PAIN IN THE
I saw this and needed it in my life.
love you videos, especially the showing the fails, because it shows what works and what does not, keep going, get high temperature concrete next time
hello integza! I would suggest to use the impeller from a used car turbocharger, they are made to withstand over 200k RPMs and very high temperetures while being perfectly balanced, plus they in most cases are free if you know someone that owns a scrapyard or a mechanic shop
Colin furzes has used them to make rockets so yea they'll survive the heat
try making this jet engine with the hydrogen peroxide rocket reaction chamber instead of a combustion chamber. the resin might last longer since the reaction is cooler. it would be awesome to see two previous projects combined into one.
You were just on the precipice of learning something very important about combustor design 😭. Once you get a setup that can take the heat better, you'll probably want to do the clamshell style combustor geometry used in jet engines (sorry I don't know how to better describe it). Basically you want to have a flame holder that prevents the full velocity air from entirely blowing out your combustion.
you should divide the mold into several parts before casting. it's like how to build a concrete column with a mold, so that it's easy to separate the mold
wowww, those white flames looked amazing!! its probably only a bandaid, but you could try to cover the surface of your prints with kapton and then aluminium tape to act as a heat shield.
alternatively, maybe you can cast some parts in JB-weld. it would be a little expensive and maybe the heat resistance still isn't enough, but it would have a much higher limit than the regular resins you are using.
EDIT: J-B Weld extremeheat is rated for 537°C !
A paraffin wax candle burns with a flame of 1000° C. It's about the coolest flame there is. Direct a narrow stream of oxygenated air at the base of the flame and the temperature rises drastically. JB Weld - High Heat burns like any other plastic in direct flame.
Heh, the white flame is probably the engine using itself as fuel, but a cool concept though!
@@3DPDK yeah i vaguely knew that fire is in a temperature range way beyond 500C, but i don't think the materials are reaching those temperatures for quite a while, since they're being cooled by a constant stream of air and would probably take a while to heat soak. not sure though. its definitely not the solution, just a band aid for prototyping at best.
although, for a rocket with a short burn, it might work.
You definitely need an anemometer to compare the efficiency of the different engines.
Video idea with the creation of a testing rig, maybe?
Starlight will work for sure!!! It's basically what they use on space shuttles for re-entering the atmosphere and not blowing up.
After seeing this video, I want to see you do a couple of things:
1. Build a fairly low-cost rocket with autopilot/guided system
1b. Bonus points if you make it do a precision landing.
2. Build a drone capable of firing paintballs that can withstand the recoil of the paintball gun.
I love your videos by the way. Never stop!
I think a nice idea would be to give your future engines a soft start which could also help them survive longer; keep up the great videos!
Probably would help, but it looks like tuning the air/fuel mixture seems to be half the battle so maybe once that is dialed in, a soft start would be possible.
I am always stoked to see what you come up with. Fantastic video! 😁 Glad to see the safety goggles in use.
not sure if the giveaway already happened but, i enjoyed the video more than i thought i would. and a build for thrust or rocket science would be... if you dont have a exhaust system already, since you seem to like to open the door, make a fan system with said technology and integrate i to the ceiling. best of luck
Lost foam casting could make a duct that would withstand the heat. Brass or bronze are relatively easy to cast, cheap, and should handle most fuels maximum temperatures pretty well
Don't know if it is possible or not, but watching this video got me thinking:
Could you make a super powerful *JET ENGINE VACUUM?*
Could be fun. I don't know😂
And it would incinerate the dust at the same time! I can see some practical use for this! (E.g. sucking up seeds from pest plants, instantly recycling them into plant feed... Or to suck insect swarms from the air in malaria regions or in Lapland)
@@lukearts2954 I didn't really have any practicality in mind, but yeah!
I have seen a compressed air vacuum cleaner, it uses the venturi effect which is basically how this was supposed to work.
I hope he does this.
@@theyeetus1428 me too😂
I think you should change the ignition spot! I think this would help with the temperature problem!
Great stuff! I didn’t realise the ceramic printing limited the complexity of what you can print. Form Labs do a printer that has a ceramic resin that needs to be proofed afterwards in an oven, I wonder would it do the job for you??… what about as a theme for next time ‘thrust vectoring’… looking forward to see what you do next! 👍👏👏👏
Amazing project!
Maybe it’d be a good idea to change the combustion point from the inside to the upper part which you made out of resin.
Abraços
It would be sick to see integza build a rc plane that uses a jet turbine he makes.
YES! It would be awesome if it worked
Personally, I would ignite the pressurized air/fuel mix in the upper part near the back end, it would preserve everything of scotching heat and avoid self destruction.
Agreed, though this would reduce the efficiency of the engine, since there is a shorter expanding tube for for the air to flow through meaning it's harder to cause as much decompression, limiting the amount of air that gets sucked through the front and the overall thrust (sorry for the bad explanation)
Would love to see you tackle producing a practical, usable Sterling Engine.
Video Idea: to improve accuracy on your heat resistant designs try to do a 2 step procedure ... 1st 3d print it in parts and make a silicon mold of it ... 2nd create a wax model of it in the silicone mold and assemble the entire piece (trim the excess parts and defects, smooth the surfaces when necessary, etc) ... 3rd make a plaster (or heat resistant silicon ) mold and burn the wax ... 4th pour the material (liquid metal, cement, etc.. on the mold) and enjoy. You will have the 1st silicon molds that let you make new wax models and make changes on the design if necessary. Tks
Video Idea: Pulse Detonation engine.
You could use an air compressor, psi sensor and spark plug to get the Detonation system and with you ability to 3d print in metal you should be able to make a functioning prototype. (and you would be the first to do it on TH-cam). The problem is that they require a lot of tuning to get working.
colin furze hasn't done this?
I just went through a marathon watching your videos... Love your content!!! One idea that came up to mind after watching your previous videos was having a weight scale in front of your next rocket build. That way you can measure how much force it puts out in pounds/kilos or having weights hooked up to your model and see how much it could pull.
Crazy idea... A Rocket Powered Generator that could produce energy more efficient!
Jetoptera intends to use an APU to drive two air compressors to power the thrusters. APU exhaust is ported.
I have seen them test their thrusters by porting jet exhaust through them, but I think they also had thermal issues.
have you tried using a silicone negative mold to make your ceramic dyson fan? Using the mold to cast the ceramic, letting it dry and then removing the silicone before putting the ceramic mold into the kiln?
As for the Dyson jet engine idea, it might be better to print it in layers that are assembled or interlocking versus one solid piece, or apply a heat resistant paint on the surfaces.
0:30 Fan on steroids. 😂😂😂
I think that putting the spark plugs near the exit will reduce the heat generated in the case and the upward force.
Maybe it will even increase the air multipication effect as the fluid will expand as it exits
Hey Integza. You should try lost pla casting to make metal nozzles. You could diy a forge fairly easily.
VI: make a fuel controller with valves and corresponding buttons as well as igniter ports. This way you can test all your engines with more precision than simply cracking open a thing of butane :) you if you included a data logging system you could have it send the perfect air fuel mix every time
Even commercial turbines don't worry about air fuel ratio to that extent. RPM and EGT are the numbers to know and watch, but that's to stop it from melting itself or flying apart, which is already an expected result of his tests, so there's really no point.
Perhaps weighing the can of butane would be practical? Otherwise, I don't know any affordable sensors that can measure flow, especially at such low levels, accurately enough to be useful in this application.
@@ParadigmUnkn0wn yeah, I know he doesn’t need this kind of precision, but it might be useful to save some time
@@ParadigmUnkn0wn it looks like he’s spending a lot of time on some engines like the pulse jet engines to get them to ignite, and it might be more useful to have his hands free
@@babayaga6662 i agree entirely with a valve and/or electronic solenoid system being useful. It's the measurement and closed-loop air-fuel ratio that's an incredibly complex engineering challenge. Even cars, at least a few years ago, only run closed-loop fueling at idle and low loads, anything more and they fall back on an open-loop system based on a lookup table equating injector duty cycle to fuel demand based on load and throttle position. I think new vehicles might be doing things differently, as wideband oxygen sensors have become more affordable and consumer demand for better fuel economy and lower emissions.
Suggestion Time: You should try to use the "LOST PLA Casting" method, where you cast a metal in the PLA mould and the PLA burns off, leaving the metal form for the jet engine!
Unfortunately the pla would melt before the metal reaches a low enough temperature to remain a stable structure.
@@jaricmcghee5931 you misunderstand how lost pla casting works. you create a fire resistant mold around a pla object then burn out the pla in a kiln leaving an empty void that is filled with metal during the real casting.
@@TheNitroG1 Ahh thank you for clarifying. My mistake.
@@jaricmcghee5931 no problem. I only know because I looked into it myself. it's a difficult multi-step process. requiring a forge, kiln, and some sort of mold material that can stand up to like 1200+ degrees.
Nice video! Kinda there is a way to make really bladeless fan. For example electron wind. But it can be dangerous.

This put a smile on my face. Liked and subscribed.
Have to be honest, I was always slightly curious about how Dyson fans work.. seeing you turn it into a jet with 3D printing was a fun way of learning!
You really need to start designing cooling channels into your parts. Your rocket nozzles need to be part nozzle, part heat exchanger, and use water to take the heat away from the surface of the combustion side of the nozzle
You could do with a cone shaped diverter to regulate the flow from the impeller to the curved manifold.
I would LOVE to see a video with a RC airplane on a bladeless fan. Jet or not. Love your channel
Idea for improvement: Have you tried moving the fuel ignition to the fan outlet? This way, you would take advantage of the acceleration of the fuel (by achieving a super thrust) while protecting the fan (because the combustion will be outside the fan). You would get an amazing tomato incinerator =)
This won’t work as the reason the engine is producing thrust is due to the expansion of air and fuel mixture when it combusts. This expansion naturally causes an increase in pressure, which leads to the exhaust to be ‘forced’ out 100s of times faster then the air mixture that’s being fed into the jet before being combusted. The mixture has to be combusted at a point before the centre line of the current outlet to ensure all exhaust goes out the correct direction which would mean it would still cause the outlet to heat up.
I would really love to see you continue this rocket and jet engine quest. One day, integza may be flying around in something he built himself. 🙃
Thanks for the awesome build. You are an included space. No ventilation. Seems like part of your home. I'd be concerned about those fumes. Next time outside or some ventilation would do your lungs well. Stay safe.
The oval shaped perimeter of some of those engine layouts reminds me of a closed wing. I wonder if additional weight can be saved by using the engine cowling as a lifting surface?
