Id recommend pla, cover it with aluminium around the engine

@@mindhealer3497 petg is stronger and little more heat resistant

I'm still alive, just very busy atm. I will try to pick up my projects in the next month.

Wonderful! Glad to hear you’re alive!

At the moment, you can't really. I am considering making the plans available online.

You mostly get to see the big view videos on RUclips thanks to the algorithm. In reality 90% or more of the videos have far less than 1,7k views. So I'm not complaining, but I did like to have more views😉

@@enginesandmore1013 this is an excellent presentation of a great project. You should have more views.

You might want to take a look at my latest video. 😉

Nope, it's radial. Axial pushes the air along the axle, radial throws it away from the axle.

​@@enginesandmore1013 nope.. the system on the video is axial.. even if type of the rotor is radial...if you rotate the diffuser 90 degree with the rotor you can not call it "compressor" anymore. It will be something else and system does not act like a compressor. (Act like an axial fan). I am pretty sure that slip factor is around 0.6-0.65 on this system aspecially on motor start. If you block the outlet on start for few seconds and open the outlet probably it will start to suck the air from outlet. Don't misunderstand me. I was trying to point out a common mistake. Can you please share the difference mechanical power, and electrical power of this system?

When using the terms axial and radial when talking about compressors, it refers to how they achieve compression. In this case compression is achieved by a centrifugal rotor, also known as a radial rotor. Once the air leaves the rotor, it Indeed starts flowing axial. This however has no effect on the name of the compressor. I have no idea what the "slip" is that you are talking about. Do you perhaps mean efficiency?

@@enginesandmore1013 slip factor does not mean efficiency but anyways.. nothing to talk about...

Its not engine is compressor but rotary (me not like a pistons)

Awesome to hear , happy to see yours working to.

Yes , electric. Multiple stage EDF

There is a little grease in there. Just not a lot.

@@enginesandmore1013 ah cool

Awesome to hear from a fellow RUclipsr.

Never thought of graffiti as a lubricant, I will look into that. Thanks

No idea honestly, I just started making this video. And for some reason it turned out way better then the rest of my videos. Although im not to happy with the amount of jet you get to see in the video. Im trying to figure out how to make it a bit better.

@@enginesandmore1013 looks like you have a lot of potential - for making videos and for the engineering part. As for some (not requested) constructive criticism, try to be as precise as possible with EVERYTHING - dimensions, cleanliness, tolerances. A resin 3D printer might help quite a lot. Looks like your builds can get a lot better just by this. Also, isn't those fan blades' (the counterrotating ones) pitch a little too steep? On the other hand you CAD and design game is absolutely on point.

Thanks for the nice words. For the steepness of the blades, I have honestly no Idea if they are good , I usually try to make them around 40° as thats what is common for rc plane and drone propeller's.

Thank you.

Its running at 7,2v lipo battery at 0,9kW. Id you wanne lake a plane for it , its gonne have to be a massive glider, because the thrust us low and the weight is 1,2kg

@@enginesandmore1013 wow, that's kinda heavy! however, as you said, a glider with a wingspan of 2m should be enough to fly with this beast!

The best so far out this thing is 750 gram of thrust. Im hoping to get more with these counter rotating propellers. Although I noticed that in general bigger is better.

Thank you

Yea lol , I told you I would improve it.😂, There was something seriously wrong with that old ring gear.

Thanks

Im have been thinking on putting up a little shop, the thing that has been holding me back is the danger of one of these exploding when someone is spinning it up, or someone putting a finger in the intake. Last thing I want is for one of my viewers to get hurt. Im currently thinking on making a desk model of my jets that cant have a motor attached to it unless the buyer actually designs a part himself.

@@enginesandmore1013 I’ll sign a hold harmless-no liability waiver 😂 I’m really just looking for a model I can physically put my hands on that’ll move air, to aid me in the r&d of a vortex reliant combustion chamber and uncoupled exhaust turbine I’ve designed and started fabricating.

@@enginesandmore1013 Its pretty Tesla-esk in design

Yea yea , its being fixed😂

@@enginesandmore1013 a bit of silicone grease would give it more lifespan for testing purposes...did you consider modifying a drill bit gearbox? that operates at a similar rpm value and its really solid!

This gearbox runs really smooth actually, but I have a hard time attaching the output axle perfectly in the centre. I took away the openings in the gearbox to keep the noise down , now I need to find a way to attach that axle correctly. Im thinking to redesign the encoder disk so that it allows me to make a longer part for the axles to attach to. Edit: so its the output axle not being perfectly centred that creates this noise.

Bet , things will only get crazier, there is currently a counter rotating prop attached to it. I probably put that in the video after next weeks video.

Yip , wont be a problem in my next video , I already made changes to the gearbox after filming this.

@@enginesandmore1013 I’m trying to build my own, and am looking at others for inspiration.

@@stevenkempton7469 my tip , dont make a planetary gearbox and go with a simpel gearbox

@@enginesandmore1013 mine is far simpler, and still on cad.

@@enginesandmore1013 just getting started really. I have set my sights high though. I’m going big.
