I turned my Dyson Fan into a Bladeless Jet Engine 

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

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.

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

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...

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

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.

​@@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.

How can I contact you to talk about some “ideas”?

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

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.

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.)

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...

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0IbWampaEcM.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.

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.

I like tomatoes. By the way i agree

Thats happening in the car

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 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 😂

Not much more thrust. No compression stage so it's just a fan-boosted blowlamp.

yupp

yes i would love it

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..

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.

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.

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

YES! It would be awesome if it worked

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😂

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

Colin furzes has used them to make rockets so yea they'll survive the heat

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.

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.

colin furze hasn't done this?

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.

Heads up a printer has a big learning curve

@integza1.. responding to winner notification?

This would also mean that you need to funnel the propellant through the parts affected by the heat in extra channels. Effectively building a liquid/gas cooling for the parts. It would probably be easier to just water cool the part as suggested in another comment, at least for now. Also cooling with your propellant makes only sense if you really cannot cool otherwise, which are normally only rockets. If the design is an aircraft engine as in this case air or water cooing would probably be more efficient. The reason for this is, you want the propellant as cool as possible when you inject it into the engine because then it is as dense as possible which means for the same volume you get more energy.

​@@FactoryofRedstone I agree but to water cool it will mean that you have a radiator that can keep up with the eat and that the water don't move too slowly to displace that heat elsewhere. Also cooling with the propellant as the advantage that you don't need the extra setup of the water-cooling, and can (detente of the propellant used) improve the trust output.
