che malfidente .....:biggrin:on the axis missing the bearings :biggrin:

that front fan with the blades in the flag wide equal from the root to the end "no se po' vedè"!
Couldn't you give him a slippery hair and widen it at the end?
And then...
we want to see the section along the axis with bearings !!!

Maybe light incautious, you would have agreed to start with something simpler.
I think you don't need to draw a reactor. but it's my opinion.
at your age I drew and cotruiii this below, and I do not know what satisfaction when, even if for a few seconds, the engine came to life.
in the image attached a 2-time motor designed and built by me
in 1991.
designed on block notes (not joke, as soon as I find the originals knead them and place them) and made with lathe hobbies and fresa traballante.
in 2003, finding the original project, I played it in solidworks.
My studies are media license. lower.
passion is everything... with studies... is better:finger:.

attach the images to the post, there is the appropriate tool (the "graffetta"), without requiring users to go on another site.
I attach a section of a turbofan (a little particular, it is part of a patent to have counter-rotating trees), it could be a basis to understand how the trees are supported.

3 crown ball bearings??????? ? ? ? ? ?
roller bearings?????? ? ? ? ?
I have enough, I come down.

Before starting a job you should do a "knowledge investigation" to get an idea of what you are talking about.
when you have carefully garded, 10 minutes a, one hundred photos and/or drawings from google, you would have the possibility to create a simplified and conceptual model, at least, credible.
instead you prefer to throw down anything.. .

only for the "chronaca", on the compressor side there can be rolling bearings, on the turbine side is difficult, temperatures are prohibitive.
often you prefer to use bearings to "oil fog", bushings, to say it in "soldoni".
But everything depends on application and size.

I associate myself with mike's thinking, try to design a different application that is within your reach, you can't leave with an object that could definitely be subject to a graduation thesis.
Finally devote at least one full day to the study of bearings in general, you will realize their great importance when it comes to design.
Start with the basics, if you want everything to stand.

I looked at our friend's old messages, and he came back to my mind where I read it.
He was looking for a model for a gas turbine for an examination where he had to show a moving object.
Now I say, what's more boring than seeing a schematized turbine in motion I don't know exactly. so much worth making a wheel, the degrees of freedom of the wheel are the same as the turbine shaft.
with all the machines that have interesting cinemas has chosen the most difficult to model and the most trivial to put in motion.
If then the prof who will see the model as soon as he knows how a turbofan is made, I have horrified, starting from the front fan with those shrivels.
"light incautious", imho you have wasted a lot of time that you could devote to modeling (better) something more interesting from the cinematic point of view

If he took a graduation thesis on a complete turbofan, they'd take it the next day as executive here. http://www.geae.com/engines/index.html As long as they do not read this thread :tongue: :smile:

What I cannot understand is:
Why do you always have such high goals when you are still being studied and even at the beginning?
I don't even know what a turbofan is (a groupie unleashed), I wouldn't even dream of typing the word on the gogol to understand what it is.
Let's put it on my own, so I'm starting to inform myself.
As the exiled president says, I look for literature, I look at photos, I fear and I pass to something in my reach.
that type of product is carried behind (and in front ) dozens if not hundreds of thinking heads, for a few decades we use fjor programs of design, calculation and analysis, we do tests and occasionally explodes something.
as you can think of introducing yourself to light heart in a theme so, I just do not understand it, I will be limited.
Bye.

I apologize, in a hurry I posted the photo of a torbojet and not a turbofan.
I hope I haven't confused the ideas even more, though I've done the debris distinctions, the example is valid for a general approach.
