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.
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.
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.
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.
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.
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".
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.
BisdremisKostas based on the lack of dust on everything around him, not to mention the reputation of this company, hes probably polishing or buffing the blade in one of the final steps.
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?
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.
+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.
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?
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.
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?
Moonshine (the drink) was made from materials at hand in a one-off, ad-hoc sort of way. In lean manufacturing, moonshine is similar in that it’s a way to provide solutions to problems by creatively adapting materials that are already on hand.
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)?
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.
I am wondering if these blades would resist canadians geese impact. That's exactly what captain Sullesburger had to deal 10 years ago when he landed in the Hudson River.
William Acuna you do realize these engines for certification purposes had 15lb frozen birds fired into them at takeoff power. This is not new, 777’s have been flying for a long ass time.
Couldn't they also attach a protective wire mesh screen on the front of the engine to keep birds, people, or other objects from accidentally being sucked in? Just a thought.
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.
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.
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
why jus not using precise metal such as solid stainless stell,,,,on same size pressure test,,carbon fibre only hold about 2.400 kg,,then solid stainless stell hold 15.100 kg is 15 ton,,wonderfull right,,thanks,,hhe
Yat Sum Leung The question deserved a negative answer anyway. I suppose the biggest difference between Trents and GE products is that Rolls Royce uses a three spool design.
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
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?
4:15 a company that produces some of the most advanced technological products, and yet they fail to replace a hydraulic table that leaks oil and loses the selected height over time :)
Draylogic sorry, I cant accept that explanation. You can see him adjusting it himself at some point. So there is no need for it to drop by itself. Besides, it drops very slow it would not be noticeable at normal speed
+loyd ala The higher the speed and the mass of the air coming out of the back of the engine, the more thrust it delivers. On fighter jets, for example, they have a secondary burner stage called an "afterburner" which increases the heat (and therefore the pressure) of the exhaust gasses. -jcr
Carbon fiber’s melting point is around 600 deg c, which is the same as Aluminum. Standard Epoxy resin, heat cured, start breaking down around 300 deg c. I believe these amazing fans have no problems sustaining a high temperatures. How is it done? And what’s the difference between traditional metal fan blades regarding temperatures. Is temperature a big issue for the fan blades in general?
No, it is the turbine blades that are exposed to high tempratures, not the propeller fans. a jet engine has blades for compressors to compress air for combustion, then the compressed air is mixed with sprayed fuel then combusted in a seperate chamber , the air is further shifted to the turbine that harnesses the kinetic energy from the combusted hot air. the turbine is connected to the propeller via a shaft. the ones in the video are propeller blades.
They don't _need_ to sustain high temperatures. They're at the front of the engine a long way in front of the hot bits. (ie, if they're getting hot, then something is going seriously wrong) On the other hand, where things are hot, R&D into ceramics (coatings and complete units) has been continuing apace for the last 40 years. Incremental improvements....
@@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!
The lips of the engine is left unpainted, because of the risk of paint traces may damage the compressor blades , then why the propeller fan is painted ?
Imagine, finding a solution as cheap as masking tape. The engineers must be the best money can buy. What would be your solution instead into the manufacturing process that would lower the cost while keeping a perfect quality of the product?
Scotch tape, Uline, 3M tape is pretty much used in a lot of industries for a lot of tasks or procedures. And there is a whole lot of special tape to choose from. This is nothing unusual.
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.
Earned a spot in the museum of modern art? Iv'e been to this museum. These blades and someones welded pieces are the only art in the place. The rest requires no skill to produce.
There has to be individual correlation between unconsciously negative behavior versus positively productive state, that said fellas know the difference between filleted and unfiltered or tamed or untamed bagger, need I say anymore.
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.
Bulbous Cock21 @3000 rippers leading edges begin to heat up. @30000 rippers you can imagine a high amount of heat. Titanium has the highest melting point to weight/ strength coefficient.
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.

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!
"In GE we THRUST", too!
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. :-)

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...

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.

@@DimMakTen I agree, defiantly not a sanding operation
The only thing I noticed that looked like "sanding" was the polishing of the titanium edges.
Only humans of skill and passion can build such things.
Reminds me of Japanese Masters of Steel ... and their tools & productions.

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.
Amazing workmanship...
I hope they will keep it mostly hand crafted.
