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.

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 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

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.

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

Dyson "bladeless" fan is just 100% marketing. Not only does it use blades internally but there's no actual "multiplication". There's no free lunch or free energy.

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.

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

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).

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.

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.

@BarneyDesmond

2 жыл бұрын

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

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.

I challenge you to build an air cycle machine that an air craft uses to cool/heat the plane. You could do this using the Dyson fan motors as the compressors.

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.

Considering most jet engines keep everything outside the turbine cool using an air cooling barrier layer, it's not surprising your fan element is melting. What you need to do is channel some of the air into the front of the intake, and form a barrier around the flame exit. You also probably don't want to burn in the vertical chamber, but in that upper element, again so you can surround the burn chamber with a barrier of air.

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

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.

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.

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

0:30 Fan on steroids. 😂😂😂

My suggestion for an upcoming video is to learn to make Silicone molds! And in turn, teach us how to make Silicone molds.

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

You definitely need an anemometer to compare the efficiency of the different engines. Video idea with the creation of a testing rig, maybe?

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

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.

​@@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.

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 saw this and needed it in my life.

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.

@marshallwilson9344

Heads up a printer has a big learning curve

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

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.

I think afterburners are a way to get extra thrust, but not very fuel efficient.

since you are printing everything, it's possible to print water cooling lines, fill it with wax, then cover everything with high temp epoxy, pus it in a vacuum pot, pull all the air out, let it outgas, then put in in a preassure pot and add 40 psi. After curing user hair dryer and heat part to 50-60C and push all wax with compressor. run hot water thru the loop and flush it. and voalia you have a liquid cooled rocket. This is very simmilar to how saturn V was constructed.

you can protect the build using refractory material or simply clay. but you should allow it to dry real well before applying heat.

1:27 POV you’re using the timed beta comment section

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 KZread). The problem is that they require a lot of tuning to get working.

Dude, This project is Omaze-ing :D

Video idea: Make a centrifuge tomato launcher!

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.

You only make your invention complicated unlike others! They make Burner and Tube air to enter it from fire to exit it!

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

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!

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.

@innacrisis6991

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)

I would LOVE to see a video with a RC airplane on a bladeless fan. Jet or not. Love your channel

If you look into Jet engines, the process for thrust is "Suck, Squeeze, Bang, Blow". Suck and squeeze is already occuring in the compressor, but there isn't really a bang, rather just a flame, and the blow is being redirected by the bladeless fan. The Bladless fan portion isn't really doing anything in the system besides redirecting the exhaust to make a cool flame.

Hey so maybe make a rocket actually fly. Shouldn't be impossible for you. Also you could make the robot arm thing from iron man to take care of the fires you cause every day. Also it should purposely burn tomatoes when it sees them.

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. 🙃

If you flip this fan inside-out, it might be the drive system for the Tic Tac seen by US Navy pilots. An ionic skin drive could cause a craft to move without a visible propulsion source. And if you turn up the power and create a thin plasma membrane around it, this is supposed to be ideal for hypersonic flight.

You should put one of your engines on a model airplane and fly it!
