45 years ago I help to build the original carbon fiber fan blades for GE in a development lab. GE has come a long positive way from our efforts.
I work in a place that makes the smaller compressor blades deep in side these engines. The machine with the probe that went around the outside of the blade is called a CMM machine. Stands for coordinate measuring machine. I use one at least twice a week at my job. It's how we know if the blades have the right pitch/angle to them. If they don't then we have to bend them to get the right angle or tolerance.
From what material are the smaller compressor blades made?
Sounds like you have a cool job. Those engines look like they are amazing machines.
I work at Ge Celma, Brazil, honeycomb cell, it is a pleasure to be part of this Ge Aviation team in the world, where so many technological solutions are developed with quality and safety, it is a fantastic job.
As a P&WC employee, I can respect what GE has accomplished here. Bravo.
The amount of hands on work always suprises me. I always picture things like this are made 100% automated.
Hand made with computer correctness
Absolutely AMAZING video! I flew in a 777-ER for the first time this summer (to Greece), and the GE90's raw thrust blew me away!
the best engines that GE has ever made.
And the blades are beautiful too. they look like a work of art
There is a blade on display at the Austin airport. It is amazing to look at.
"In GE we THRUST", too!
Absolutely amazing. Thx for the video. Keep up the great work and art.
Miss this job. I deflashed the Genx 1b and 2b, and 115b blades. I also prepped the wearstrips. It was a fun job, great people to work with and great environment as well.
+Brendon Milligan Their lightness seems unreal.. 10 pounds? I'm guessing maybe 15?
Cool job Did you guys make the composite fan cases in house as well?
No, just the blades sir! Sangyoon Kim, I don't exactly want to give exact specifications of the blades or measurements out of fear for lawsuits lol! But yes, the blades considering their size, were relatively light-weight. GE115-B blades were of course the heaviest.

Very nice. I especially like the shot where the employees in a circle, each laid down a fan blade and the blades became a fan in the engine. :-)
Did you see how fast those workers were going....amazing 👍
Every maintenance tips are valuable for all the engine maintenance technician s
Interesting!!! One of the finest job in the production world.
Very educational and informative video. Thanks for producing it.
Very speedy fan presentation is very impressive thanks for sharing
Amazing workmanship...
I hope they will keep it mostly hand crafted.
Art and work all together.
I love the ending!!!!!
+Jeffery Jin Definitely. It really makes a mark showing the involvement and importance of their people that make this highly advanced technology possible. A team effort that is advancing the modern turbofan into a new era.
Only humans of skill and passion can build such things.
Reminds me of Japanese Masters of Steel ... and their tools & productions.
Watching this I am wondering how much would the blade profile change if you start using a gearbox between the fan and the turbine driving it. How long before we start seeing engines with reductions between the front and the back end blades?
I just want to be a cleaner there so I can always look at the amazing work these men and women do
I am Ex employee of GE i wish I would rejoin one day.. GE is the Best organization in this World.
That's a very good video.
I'd like to see more detail on how you do the lay-up. I noted a big bunch of fibre cutouts, but how do you know where each one of them fits in the blade? On which layer, and where on the blade form?
I wrk at an airport and the GE90 engines are huge
What is the percentage of carbon fiber volume fraction from Carbon fiber/epoxy composite for the GenX engine fan blade? Also which type of Ti-6Al-4V alloy is used as the Leading Edge of the fan blade?
Great video.☺️ My favourite Jet engine is the GE90.☺️ I think I’ve watched this video before.☺️
Credit also to Rolls-Royce in being the first in trying to get this technology to work with their RB211 engine, even if they failed. As Isaac Newton said "We are all standing on the shoulders of giants".
This video made me a fan
Nice job guys!
Great technology!
Can two blades be made to stick together during a flight to allow for more space in between blades to reduce drag on motor espcly if it needs to turn double it’s speed(supersonic)?
Awesome!
The three dimensional S shape of the blade provides the ultimate in efficiency. Powder high strength ceramic coatings of the blade face could add extra strength to the overall rigidity.
The best part starts at 3:37... it's so visually satisfying.
Fantastic!!!
I'm a big fan!
Nice of GE to include a shot of the 787 prototype with its clearly visible Rolls Royce engines! 2.03 in the video
Considering all the flaws of those RR engines it's no wonder that a change was made.
They were showing you the plane, and listing the engine
I’m curious if the blades for all your engines have the same profile, with the only difference being length, to account for engine size? I realize that there will be different profiles for different applications, but I mean overall.
very nice i work with composites and your factory runs well great job
amazing video.
My brother is none destructive engineer, he worked on the inspection process for the shrouds they make to keep these blades from coming out of the engine housing in the event there is a reason they come apart, IE flock of birds hit the engine fan blades or there is some other failure like they had on the Southwest plane that experienced a broken fan blade. The carbon layup is incredibly strong, the sample section he has of the fan shroud is like 4" think pure carbon fiber. The carbon fiber blades are quiet compared to traditional titanium fan blade, I believe that they are better because the material they are made from allows for them to be shaped to perform a specific duty, the curves you see actual allow for more air flow for given diameter, engine speed, and engine type.
Definitely not 4" thick pure carbon fibre...it'll be a combination of carbon fibre and Kevlar, and won't be 4" thick
@@Penguin_of_Death It's near 4" thick, it's the band that encompasses the primary fan blades...
Sweet blades bro...
Beautiful
Are the titanium sheaths that go on the edges made in house as well?
very cool!
WOOWW AMAZINK👈👈
I wanna work there... impressed..
Awesome technology (y)
Best job in the world!
Great people great job
Yes a good team who cares about the company and wants to be the best team in the world do have the best people
Assuming graphene and carbon fiber become more ubiquitous, would they use that feedstock? Is there any incentive to?
What about unducted fans using graphene carbon fiber?
Where are the engineers who designed these things?
amazing quality.

Looks like a dream to work there
Hand made how nice
I'm extremely impressed and would like to say thank you for your help with the policy's and and procedures you're amazing work and timely matter is much appreciated and think can we fix your magnetic pool on your fan blade make one side positive the other side negative so that it can allow for push ball bearings and a copper plate to help with your rotation of your energy
what about the inner turbine blades inside the combustion chamber? are those still made of level 5 titanium alloy?
Inside chamber has no any blade but it has afterward. Those are made from nikle alloy.
COOL!
great nice video
How about Tech Now whats new fiture on the GE for star the future
GE Aviation, you need to get a synchronized swimming team to recreate the shot at 6:49.
Thanks for the fantastic video!
Good job 👍 I want to work there
As the victim of four propeller fatigue failures, I want to know more about how the blades are built up, and I would like to know such as if any moment force is carried by the "fir tree" blade root and what do the blades weigh. Nice look at your operation, anyhow.
FOUR propeller failures?? I think maybe at least you've used up your bad luck!
That’s a pretty blade.
God speed ge
Euler its great
Ge the only way to fly
GE is still producing its engines manually ?
Anybody know how much each blade weighs.
A very interesting video. Carbon fiber is difficult to work with. I'm trying to build a Schreckling turbine with 100% carbon fiber compressor,,,not easy.
ขอบคุณครับ
Huge!
The cutting tools for machining aerospace parts must be very carefully selected.
Did composite blades ever take off?
I would say most of the blade is C.F. with the exception of the leading edge,but I did notice that the entire perimeter of the blade is capped off with the titianum.I would have to get a close look to see.Rolls Royce engines usewtal blades,and the have a very unique and cool way they produce them.
I bet they're working on automating this process.
Some work done manually and maximum work done by autoclave molding process just like oven structure of component is designed and put into the mold after laying of papers and doing vacuum processing they send it into autoclave molding machine removal of material is done at the end.
Using monkeys?
Wow nice kapan saya bisa ke workshop kamu
blade is 100% composite, the leading and trailing edges are bonded with titanium. BEST blade in the business. :)
NICE!! I'd like to see what the blades look like after Bird strike testing....
Exactly what bankrupted Rolls Royce in 1971. They built the RB211 engine with carbon fibre blades and it failed the bird strike test.
IIRC it was the Concorde engine's development that almost took R-R down.
You should see what it takes to make the hub that holds all of them together. Thats another story on its own.
So... You have a group dedicated to producing moonshine? Dang.

How many CSN the blade have?? I am an inspector of RR LPC Fan Blade. I HATE FULL Ti FAN BLADE!!!
I was wondering when the day would come that they would make an engine like this, that could produce upwards & over 100,000 lbs. WTG guys!
Christofer Riche dude have you been living under a rock? The GE90-115B is almost 15 years old (maybe older)
@@superskullmaster : I didn't know. New engines are not something I stay informed about. Okay, so it's old to you & others, but to me it's not. Do you really expect that people stay current with this info.? I think not. Please give me the benefit of the doubt. Thx!
Good
Isn't CFM the joint-venture between GE and Snecma???
sir how to apply ur company GE..
Can I buy a model of these engines?
6:05 yup could not have been done without ye ol white lighting
AWESOME !!!! freaking awesomeHigh dilution report,max footprint in minimum space.
I really want to know of the high tech WATER sprays , how do they recycle all the hundreds of gallons of H2O to use again ? Certainly the used water has to be purified over and over to make sure absolutely no type of materials are in the water which could damage the blade fans.
It's extremely important to continually make sure that the water is as pure as water can possibly be .
To think that the consumption of water is gigantic in terms of number of gallons continuously used. If anyone knows the answer , it sure would be a good thing to know your input. Thanks.
composites i never knew ( i neeed to get out more)
The thing I noticed was all the machine labels, signage and cetain tools were blurred out. Proprietary secrets need their protection.
GE. And Boeing The very best
I would like to learn more about GE Aviation’s use of composite material but your video is private. Please open this video.
Ge90 Jet engine ki bled kuch bejo🙏
I think just one fan blade cost as much as a family car am pretty sure I heard that somewhere like roughly around £ 7000 carbon fibre is very strong and very light and exactly what fishing rods are made from
