Just in case you weren’t aware... the tight tolerance you have does not replicate real turbine engines. Fan blades on full size aircraft have some slop to them. Centrifugal force keeps them pulled away from the hub and “locked” in place.
@@arthurwilliams3479 No...He means that the blades are not rigidly held in place and will move back and fourth. What keeps them locked and not moving is simply the force of the blades spinning quickly in a circle, thus pulling them outward and away from the spinning center of the engine
@@arthurwilliams3479 No, what he is saying is that the fan blades are not rigidly held in the N1 fan disk. The blades have to float for many reasons. The N1 fan blades twist into maximum pitch as power is delivered to the the N1 shaft via the power turbine shaft, N2. Another reason the blades float are to negate any vibrational inputs to the N1 shaft due to a “locked blade.” Locked blades are our number one cause of high vibrations that are indicated to the flight deck crew via their EICAS display. The blades DO make contact with the outer acoustic liner as they grow from centripetal forces. The liner is an ablative material and they are changed when the gap becomes excessive. Typically the N1 fan blades are removed from the N1 disk and lubricated at their roots with a special molybdenum disulfide based lubricant that is applied by spraying. Each N1 blade in a large turbofan engine costs anywhere between $17,000 apiece for a simple titanium blade, up to the mid-$100,000 per blade for the engines on the 777 , 787, and the A-380, which are a magnificent exercise in engineering delivering a blade made of a composite of titanium and carbon fiber. Just saying…
@@arthurwilliams3479 Unfortunately I’m not smart enough to navigate the posting gauntlet that is inherent with RUclips. Would be fun though, explain how these big air pumps work in detail.
So very curious to see just how far you take this project. I'm envisioning a frighteningly accurate turbofan replication somewhere down the line if you're getting into the this sort of level of detail. Very, very cool.
in a normal turbine they do have large tolerance that the blades can even be moved/shaken by hand ( not while operating though). this is to account thermal expansion. it will not shake in place if its rotating at high speeds. the designers are more concerned about the blades inertia as that will certainly make it shake. that is why the blades are segmented.
Congratulations, very cool, can you tell me which printer you used and if not too much what resolution and setup because I found the most perfect print I've ever seen like that! thanks!
Where can I buy your fan? I like that,have you ever tested it in a destructive testing so that we could know what is the limitations of your fan when it come to centrifugal force?
Hi Steven Ginn , yes we do sale the 3d model. For more information please visit our website morethan3d.com or email sales@morethan3d.com so we can assist you further. Thank you

@Howie Murray That Is An Excellent Observation.😯

Perfect job!
a very accurate replica, nice work
You’ve got some curious viewers mate. Have you done any tolerance tests with the design yet? Would love to see them

Not always.
Would have loved to be able to purchase the STL file of this fan only rather the whole kit you sell.
that looks outstanding
How efficient it would be as a wind turbine ?
Congratulations, very cool, can you tell me which printer you used and if not too much what resolution and setup because I found the most perfect print I've ever seen like that! thanks!
Awesome work 😊👍💐🇪🇬🇪🇬
you can replace the blade if one broke? because i cant se you can get it out from the other side.
Marvellous....🤩🤩🤩👍
Looking a great !
so impressive
Will it actually produce thrust ?
What is the largest diameter that you can print? Thank you?
Brilliant mate. Very accurate model. Is this the new Rolls Royce UltraFan engines replica?
Very nice. Is it correct theory for the fan blades to be so axially aligned at the base? they have almost no slope. Is it based on a real engine?
The type of 3D printer you use and what's the price of these printers
I would like to see this setup on a heavy lift drone or a vtol taxi. Where did get the fan blade design from?
i dont think trubofan work on taxi VTOL. are to noise to powerfull biger and consume a lot of fuel. On taxi vtol must be eficient, low noise.
What kind of printer do you use
I would like to see how well it hold togeather if you spin it up
It would withstand very high RPM. balancing it would be the only obstacle
Where can I buy your fan? I like that,have you ever tested it in a destructive testing so that we could know what is the limitations of your fan when it come to centrifugal force?
Hi Audi C. C., yes we do sell 3D Model of this. Please contact sales@morethan3d.com and our team can assist you further. Thank you
What software do you use to design thesr
Очень круто !
what printer did you use to print the blades?
Maybe ultramaker
Chào bạn mình đang thiết kế một cái động cơ phản lực cho máy bay rc, bạn có thể cho mình file 3D để mình tham khảo được ko
Wow that's beautiful! Can anyone tell me where to buy something like this, please...i dont have 3d printing machine anyway
Hi Ryo, if you drop us an email to sales@morethan3d.com , we’ll assist you with the purchase. Thank you 🙂🙏
Hi i know you are werry good knowledge in electrical jet engines please send me edf fan details about 14kg trust and 10000rpm
Olá amigo me manda o link de compra
Hi, are these available for purchase in a kit like this?
Hi Jo Malone, yes we do sell them as a kit so you can assemble them. Please contact us at sales@morethan3d.com so we can assist you further. Thank you
Next step is to balance the fan at 50K rpm
Класс
Hi, do you send this? Yes, what is its price? I need such an engine. If you have a seller, please contact me.
Do You sell these My friend ???
