( khap khun khrap )
I must admit that I did it as such:
google pictures
type turbo fan.
Extend the search.
And you see the pictures.
Do a final check by blade count and it should be fine.
The blade count took most time, about 1 minute.
But...as I learned from Flanker, a blade count can be misleading !

555, but when you refer to the blades, use the term "Fan Blades" it sounds more professional...;-)...

just as a side note: manufacturing those blades is a very complicated process, even if they are made in the old fashioned way out of solid titanium.
The billet has to be preformed and what follows is squeezing the material in a die under enormous pressure. These kind of blades with a 90° support is an extra challenge to fill the blade in every corner.

some manufacturers active in this field:
http://www.leistritz.com/remscheid/en/0 ... ufeln.html
http://www.mettis.com/markets_aeroengines.html

besides of pressing/forging, those aerofoils can also be cast ( hollow ! ) and new trends are to make them in carbon fibre material.

If you see the process it looks very simple. But I can asure you that they belong to the parts on an aircraft that ask the most of manufacturing techniques.

OK, back to the quizz... ;)

You are right khun Regi, they also are very expensive...

I think Techspace Aero in Liege is manufacturing the LP compressor disk for the GE90 on the first quizz picture.

I would like to say RB211 - but I am not sure because of the curves.
Anyway, because there were many variants of the RB211, that is my bet.
