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.
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
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.
There is a blade on display at the Austin airport. It is amazing to look at.
"In GE we THRUST", too!
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.
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. :-)
And the blades are beautiful too. they look like a work of art
Did you see how fast those workers were going....amazing 👍
Every maintenance tips are valuable for all the engine maintenance technician s
Absolutely amazing. Thx for the video. Keep up the great work and art.
Very speedy fan presentation is very impressive thanks for sharing
I am Ex employee of GE i wish I would rejoin one day.. GE is the Best organization in this World.
Art and work all together.
Only humans of skill and passion can build such things.
Reminds me of Japanese Masters of Steel ... and their tools & productions.
Amazing workmanship...
I hope they will keep it mostly hand crafted.
I wrk at an airport and the GE90 engines are huge
Interesting!!! One of the finest job in the production world.
Very educational and informative video. Thanks for producing it.
The best part starts at 3:37... it's so visually satisfying.
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.

Great technology!
I'm a big fan!
This video made me a fan
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.
very nice i work with composites and your factory runs well great job
Beautiful
Nice job guys!
I just want to be a cleaner there so I can always look at the amazing work these men and women do
Fantastic!!!
Awesome!
Yes a good team who cares about the company and wants to be the best team in the world do have the best people
I wanna work there... impressed..
amazing video.
Sweet blades bro...
Great video.☺️ My favourite Jet engine is the GE90.☺️ I think I’ve watched this video before.☺️
Awesome technology (y)
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.
Great people great job
very cool!
Best job in the world!
WOOWW AMAZINK👈👈
Hand made how nice
COOL!
Euler its great
great nice video
Looks like a dream to work there
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".
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...
That’s a pretty blade.
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?
Huge!
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
GE Aviation, you need to get a synchronized swimming team to recreate the shot at 6:49.
Thanks for the fantastic video!
God speed ge
blade is 100% composite, the leading and trailing edges are bonded with titanium. BEST blade in the business. :)
Ge the only way to fly
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
amazing quality.

Good job 👍 I want to work there
Great, opportunity for everyone...
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?
ขอบคุณครับ
Good
AWESOME !!!! freaking awesomeHigh dilution report,max footprint in minimum space.
Wow nice kapan saya bisa ke workshop kamu
being a mechanical engineer myself i always favoured the titanium fan blade approach by RR much more because of the borderline insane properties of that metal when it comes to shaping it into the form you want to. it's much more of a challenge obviously...
with that said i really appreciate the effort by GE and this company by making it work with carbon fibers, the blades look absolutely great.
GE. And Boeing The very best
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?
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.
Because of the composite fan!
You should see what it takes to make the hub that holds all of them together. Thats another story on its own.
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.
6:05 yup could not have been done without ye ol white lighting
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)?
Are the titanium sheaths that go on the edges made in house as well?
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.
i love airplanes i would like to be an aircraft technician
magnificent....
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.
moonshine :)
The cutting tools for machining aerospace parts must be very carefully selected.
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?
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!
composites i never knew ( i neeed to get out more)
Niceeeee
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?
The thing I noticed was all the machine labels, signage and cetain tools were blurred out. Proprietary secrets need their protection.
Salute to American Ingenuity 🇺🇸🇺🇸🇺🇸
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!
Where are the engineers who designed these things?
GE is still producing its engines manually ?
How about Tech Now whats new fiture on the GE for star the future
RR must still be reluctant to use all composite fan blades since their RB-211 fiasco with composites.
They use titanium in their fan blades.
Can this technology be retrofitted into older engines? It could make a world of difference for planes from the mid-century--way cheaper and faster than a complete re-engine.
Did composite blades ever take off?
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
