GEnx Engine for Boeing 787 Test

[FanRailer]

still haven't fixed the title i c..... =p

[GuruPilot]

@FanRailer Done

[Enanon]

What's the big round thing that comes in at 1:39 plz?

[icyplanetnhc]

GEnx-2B is for the 747-8. The 787 uses the GEnx-1B series.

[MusicLover11325]

4 dislikes are from CFM, RR, PW, IAE lol

[TheBreakdanzkat]

@MusicLover11325 CFM is part GE, so the 4 dislikes are from Snecma, RR, PW, and IAE.

[MusicLover11325]

@TheBreakdanzkat  Oh,....

[Riechode]

RR Trent XWB will have blisks, compressor blades and disk in one solid piece.

And did you know Rolls Royce hold the patent for the swept fan blade that makes these new generation turbofans possible

[turbojetta100]

@Riechode The original swept fan blade design is patented by the germans from the 1950's. They called it the "triple inflection leading edge". Probably why Pratt, GE and Lycoming all use swept blades. The RR patent is meaningless.

[JunatHaisee]

Nice vid. I think this engine is better than that Rolls Royce, because those Rolls Royce engines keeps exploding. Rolls Royce exploded in A380, exploded in 787...

[rb21122b]

@JunatHaisee True. It also happened on the British Airways flight 38 crash (777-200) a few years back. Ten of the passengers are trying to sue Boeing for something that RR was at fault at.

[UstadonKaUstad]

I would like to just remind every one that the old axis countries are prohibited from making any aero-engines/aircraft. If this arcane warsaw act is thoroughly abolished, then watch out! BMW/MTU, Snecma, several other engine makerss and of course Airbus and the japanese will be rightfully producing the best engines and airplanes.

[PaganEgyptian]

Great Video. In response to the older post, remember, The US Air Force only uses General Electric Engines. The CFG6 is on the KC10's. Here is why I love GE engines over Rolls. .geae.com/engines/commercial/g­e90/

[dwildkat]

Does anyone know what the big ball at 1:40 is and how it works?

[05u16hep]

Airbus rejected the GEnx for the A-350 because it dindnt match the efficiency requirments. Trent XWB however :-0

And to the comment below, the fan disk did explode on a GE-Cf6 on a DC-10 AND left the fan casing, two catastrophic faliures in one.

[scaremengaviation]

@05u16hep Airbus didn't reject it. I thought GE Aviation refused to sell it to them.

[TheBreakdanzkat]

@scaremengaviation I'm pretty sure they didn't want to power an aircraft that will compete with their GE90 powered 777s.

[scaremengaviation]

@TheBreakdanzkat Iit's a deep, complicated, agreement with Boeing. I'm sure that even if Airbus wanted the GEnx, GE might make more out of an "exclusivity" deal to power almost-all 777's. Boeing might pay GE a premium to keep that deal valid... not to mention the two-engines per frame. Not sure. Aviation politics! =/

[mike40842]

Have GE managed to actually deliver their attempt at an engine for the 787 yet or are they still Imagining

[jeetendrag10]

jet engines are impressive by nature.

old or new,big or small,running or static,they are simply awesome pieces of engineering.

their symmetry instinctively reminds the human brain of something extraordinary,cyclones,galaxie­s,black holes,vortex,and what not.

SOmekind of circumstancial poetry carved with mathematics and physics in a sculpture of titanium and ceramics.

[steve45coe]

get over it little american buddy, I had told you it was my last post and you continue your drama. I know that engine, you govrnment wanted to cut the program because it was proving to be very expensive and wanted to stay with Pratt's engine ony but they did not. I just hope you understood the explanation about the HP Turbine cooling system, VSV systems, etc. Take care

[EpiDemic117]

@steve45coe "you govrnment wanted to cut the program because it was proving to be very expensive and wanted to stay with Pratt's engine ony but they did not" My government? Why does your profile show Country of origins as the United States? The F35 is a investment between Europe and the United States. There are Two engine variants for it. Next time you want to comment. Check your facts and don't be a douche.

[steve45coe]

@EpiDemic117 I never said it was not aN investemen between EU and USA, read what i wrote again. I did say your government wanted to cut the GE/RR engine option, which is true. And it is so true that GE was promoting that US citizens write a letter to their corresponding senator in support of the alternate engine, you should know this since you are one little american citizem (i guess).

[EpiDemic117]

@steve45coe " read what i wrote again"

"you govrnment wanted to cut the program because it was proving to be very expensive and wanted to stay with Pratt's engine ony but they did not" <----- Quotes don't lie.

[steve45coe]

@EpiDemic117 I guess the pressure ratio in your skull is so high that is causing your brains to be ejected out of your ears at supersonic exhaust velocities causing you millions of punds of thurst of ignorance. Please have some some dignity and do not reply to this.

[steve45coe]

This engine sucks. It was designed mostly by the GE global engineering team (cheap engineers from india, mexico and poland). And the few parts that were designed in america, well ... you know the reputation of american products 8say chrysler).

[EpiDemic117]

@steve45coe This engine does NOT suck i can tell you that for certain. Do you know how much it costs to make just one of these? It isn't cheap that's for certain. And no most of iit's design is done in north America.

[steve45coe]

I don't know how much it costs to make one of those but one thing is for certain, american products have poor quality and i don't want to fly in something that has a bad reputation. Personally, I always try to fly in airbus planes with RR engines (eurepean technology with good quality). Make some research, most of the air accidents have been caused by american engineering problems

[steve45coe]

[EpiDemic117]

@steve45coe "american products have poor quality and i don't want to fly in something that has a bad reputation." What the hell are you talking about? GE probably has one of the best reputations for reliability. You are trying to compare airplanes like you compare cars? No no no no. That's not the way the Aviation industry works. These engines are rigorously tested in some of the most extreme conditions. Some even more harsh than what would be expected in real life conditions.

[EpiDemic117]

@steve45coe "Personally, I always try to fly in airbus planes with RR engines (eurepean technology with good quality)."

I think you need to research a little about some of the problems airbus had in the past as well as Rolls Royce. They are still both excellent airplane manufacturers but their quality is no different than Boeings. You cannot compare the two like you can easily do with American Vs European cars. It simply does NOT work!

[steve45coe]

@EpiDemic117 By the way you defend GE, i can tell you are a GE employee. Don't let the bonds between your financial support and yourself blind you when it comes to assess relaiability. "Aircraft Engines are incredibly difficult to make due to the thousands of parts they contain" you mean GE makes difficult to make aircraft engines due to the millions of parts. GE should keep it simple, RR has made unnecesary the use of VSV to achieve a free stall operation, reducing a lot the number of parts.

[EpiDemic117]

@steve45coe Boy are you quick to be making wrong assumptions. And NO i don't work for GE. I simply know what i'm talking about.

[EpiDemic117]

@steve45coe " you mean GE makes difficult to make aircraft engines due to the millions of parts." Yeah GE makes engines so complicated. That way rolls royce has it the easy way to just but 1 part inside the entire engine.......

It almost sounds as sarcastic as you but I'm no master at acting stubborn and ignorant.

[EpiDemic117]

@steve45coe Respond to this video..."RR has made unnecessary the use of VSV to achieve a free stall operation" Believe me. No aircraft is stallproof. MY advice is to do a little research before heavily talking shit about something. Both Rolls Royce and GE make almost identical products in certain areas and have to undergo punishing tests to even be certified. Trent 900, Ge 90. Both similar in design. Now stop being a little troll and get your head out of your ass.

[steve45coe]

@EpiDemic117 Ok, you crossed the line and stared talking with bad words, which displays how edgy, uneducated and ignorant you are. This is my last review and hope helps you a little. I'm going to stick to the FACTS.

[EpiDemic117]

@steve45coe "Ok, you crossed the line and stared talking with bad words,"

You've already crossed the line by being completely ignorant and close minded and failure to acknowledge other aircraft manufacturers.

[steve45coe]

@EpiDemic117 1. GE still needs Variable Stator Vanes to avoid a stalled compressor, while RR avoids it with a better compressor blade design, better controlled core speed, better compressor inlet guides. The bottom line is, RR needs less number of parts which means simpler products with more reliability.

[steve45coe]

@EpiDemic117 2. Many airlines cancelled their flight due to the iceland volcano ashes because some of them have GE engines. GE uses a cooling system in the high pressure turbine blades that consist of a series of holes that provide cooling air from the compressor. The ashes could melt in the combustor and solidify in the turbine vanes and clog these holes

@steve45coe "Many airlines cancelled their flight due to the iceland volcano ashes because some of them have GE engines."

Yeah so instead they can let all the airplanes go with the RR engines straight into the ash cloud!

"GE uses a cooling system in the high pressure turbine blades that consist of a series of holes that provide cooling air from the compressor" Rolls royce does the same thing. Otherwise the blades on the Trents would melt.

[steve45coe]

@EpiDemic117 clogged holes mean turbine vanes likely to melt or deform. RR just manages the temperature at the entry of the HP turbine better without compromising the engine efficiency and uses better materiales with inovating heat treats. If everyone had RR engies, probably flight wouldn't have been cancelled

[EpiDemic117]

@steve45coe "and uses better materiales with inovating heat treats" GE does the SAME THING! And by the way. You can't even spell "materials" right or even "innovating" How the hell can people take you seriously in an argument? You are just trying to be a little troll.

[steve45coe]

@EpiDemic117 so YOU do some research, ask the airlines for their records of engine malfunctions and see it by yourself. Take care, goodbye.

[EpiDemic117]

@steve45coe I've seen seen an airbus have it's rudder shatered due to pilot error. Did you know that most accidents are caused by pilot error? Mechanical failure is normally rare, But again you need to check what you are talking about.

[EpiDemic117]

@steve45coe Ok i will go straight to the airport out of nowhere and ask the company for their hidden archives and their maintenance log.

[steve45coe]

@EpiDemic117 BTW, when I was talking about the HP turbine, I meant turbine BLADES and not VANES. My bad... anyways, US products suck

[steve45coe]

[EpiDemic117]

@steve45coe "anyways, US products suck" I know plenty of European products that suck. Worse than the us. When it comes to cars. The US sucks. When it comes to Aircraft. NO. Because there is no room for error to suck in the aviation industry.

[EpiDemic117]

@steve45coe I just don't understand why people like you can be so ignorant about half the shit you don't know about. If GE makes such "inferior" products. Please explain the General Electric/Rolls-Royce F136? A partnership between the two companies and both of their expertise to produce this engine for the F-35. Your a complete idiot and waste of time if you think that North American plains are junk. Which they aren't. The 777 has the best safety record.

[steve45coe]

@EpiDemic117 get over it little american buddy, I had told you it was my last post and you continue your drama. I know that engine, you govrnment wanted to cut the program because it was proving to be very expensive and wanted to stay with Pratt's engine ony but they did not. I just hope you understood the explanation about the HP Turbine cooling system, VSV systems, etc. If you need assistance regarding how jet engines and turbofans work just, let me know. Take care

[lekkousa]

Remember the DC10? GE was the exclusive engine supplier to that doomed project, until Northwest Airlines said they wouldn't buy one unless it had PW power, NW President Bill Nyrop, when asked about his demand for PW power said, "GE is a fine company, they make one helluva good light bulb".

It was only the Cf6 Ge powered EDC10's that had the fatal accidents, many because of the engine itself!

[EpiDemic117]

@lekkousa "GE was the exclusive engine supplier to that doomed project," It wasn't doomed. In fact most of them are still in service primarily by Fedex.

"It was only the Cf6 Ge powered EDC10's that had the fatal accidents, many because of the engine itself!" The CF6 is one of the most successful power plants to date. It power's most airplanes in the worlds jet fleet. BTW the CFM-6 was a partnership between GE and a french company. GE has also done partnerships with prat.

[steve45coe]

@EpiDemic117 The CF6s that could not resist bird ingestion in the Hudson is a proof of it, and the engines are supposly FAA certified against that. I just express what I think it's the truth. RR engineering team is all based in UK, they do not try to save money by hiring engineers from 3rd world countries.

[EpiDemic117]

@steve45coe "The CF6s that could not resist bird ingestion in the Hudson is a proof of it" What because of a random engine failure? I've seen plents of RR's that had engine failures due to mechanical faults. But that still doesn't mean RR is a bad company. Aircraft Engines are incredibly difficult to make due to the thousands of parts they contain. Also I've also seen a few CF6's that took bird ingestion like you described without engine failure.

[allaboutconor]

i thought the 787 had Rolls Royce Trent 1000 engines?

[rb21122b]

airlines have a choice of either GEnx or Trent 1000.

[dookiekong007]

@allaboutconor thats the 380

[allaboutconor]

@dookiekong007 no i think they use them on the 787

[viceroytennis]

@allaboutconor. Yes, but both the 787 and A350 are competing for the same customers. Many 787s are being leased through GE, so I presume the GEnx will be bolted on as comes with, but customers can specify RR if they really must. Despite all the carbon fibre of the GE engine the Trent is about 200 Kg lighter. No doubt both will be very good engines.

[NJRocks281]

what the hell is the point of putting a cover on it if it's gonna be flying outside and running over 1,000 degrees F

[operazanotaijin]

BTW, GE vs RR orders: GE-378, RR-220. You do the math.

[viceroytennis]

@operazanotaijin A350, RR-over 1000, GE-0. You do the math!

[operazanotaijin]

We're talking about the 787, to hell with Airbust.

[operazanotaijin]

This is a GE video! For those who love GE! Not for any other engine manufacturer!

[harold562]

@applesweeter

=/ first on fsx now on this, stop this spam, we love flying because we do, its fast and reliabably, want to build new planes for our own comfort and the world's. it is not a success, its a dream that came truth. and because we were chosen and given the inteligence to do so >.> satisfied? stop this S H I T

[applesweeter]

To: harold592

Watch you language!! :(

I have my freedom of speech and my right to aqsk other for opinion.

[venichen1]

this is the best selling 787 engine.

[gcoochy]

Nope, it's the Trent 1000 my friend, already flight tested and has 52% of all orders

[viceroytennis]

It's about time this engine was up and running. The Trent has waited for two years on the Dreamliner to be started up.

[venichen1]

they tested this engine a year ago and is already certified before the 787's original planned first flight date (September 2007).

[yukkmouf]

Should of kept it on the truck and fired it up hard!!!!

[Louis1059]

Would sucked of it fell of the truck

[sloppiexx]

Oh so this new GEnx is going to be used on 747-8 and 787 ?

[Mdl1038spl]

The GEnx 1B is to be used on the 787 and the 2B is to be used on the 747

[gcoochy]

No just the Dreamliner Boeing 787

[jbird0168]

Is there a reason GE wants us to relate their engine to a bad version of Iggy Pop?!

[operazanotaijin]

GE = epic win.

[knight2k72]

Why didn't they just use (or mod) the already awesome GE90s?

Anyone know? (if you're going to rude, just don't bother)

[knight2k72]

By the way, what I meant was, the GE90 is more powerful than the GEnx-2B and Trent-1000 isn't it?

I guess fuel efficiency noise reduction = less power.

[MetalbirdsAviation]

It depends. Some versions of the Trent 1000 are more powerful than the GE-90.

For example the Trent 1000 that will power the 787-9 will be 90,000lbs thrust compared to the GE-90 that powers the 777-200 at about 77,000lbs thrust.

However yes the most powerful GE-90 found on the 777-300ER is the most powerful at about 115,000lbs thrust.

[rb21122b]

Actually, the GE-90 is more around 94,000lbs thrust and the 115b is about 127,000lbs thrust.

[MetalbirdsAviation]

i was going on certified thrust ratings.....

[rb21122b]

oh ok, my fault. sorry.

[TheAeroman]

Well the GE90-115B is quieter yet more powerful than previous models :)

[chuntohk]

Actually, you do not need that much power of GE90 on 787 and 747-8. Putting a too powerful engine on a plane may result in more increased wear than usual.

[MetalbirdsAviation]

Well I am pretty sure the new GEnx engines are derived from the GE-90 so you could say they are "modifed" GE-90's in a way.

I guess from a marketing point of view its nice to give the impression of a new engine seeing as the GE-90 was first brought out mid 90's.

[jimmorris62]

the fan stator is composite as well as the blades

[TV843]

The GEnx are simply upgraded GE90s. More carbon fibre in the blades and overall construction and a redesigned combustion assembly.

[TheAeroman]

One thing leads to another, however newer engines are usually derivatives of the models they come after.

[skylinedesigner]

the GE90 is too big for the 787 and the 747-8, plus, the GEnx is designed to replace the aging CF6, and the GEnx is more efficient than the GE90.

[jimmorris62]

GE don't want to downrate the GE90 they have two engines which do not over lap in thrust and are for different application. They already have the GP7000 which is a pratt GE joint venture

[malicios]

The birth of aviation is in Ohio so ofcourse! Screw North Carolinas first in flight... We gave birth to the ultimate way to travel. O and yes, this is in Ohio.

[GamingDude12]

thats what you call american muscle right there

[gcoochy]

English muscle is better... Rolls-Royce

[operazanotaijin]

@gcoochy Wrong.

[Tata996]

What's with the hick music?

[engieDude]

Are those engineers assembling the engine? Or are they technicians?

[smartbotX]

why did they have that heart sign sticker on the engine?

[aznturtle1]

a airliner with out its engines is only heavy metal just like a person without a heart :D

[engieDude]

Because engineers like to express love for what they do.

[redslownight]

handcock =D

[PaganEgyptian]

awesome job, thanks for posting! I always love to see how GE is keeping ahead of the competition. I Look forwards to wide release of this engine. Maybe it should be given to the USAF instead of the CFM80-C2's for their C5 RERP.

Keep up the great work.

[operazanotaijin]

That machine at 0:04 looked like it was hungry saying, "Feed me!"

[hypersupermamado]

OMG ,thats why i trust every single plane that has one of those,because of all the tests the engine has to pass for a secure validation.

[cddagr]

beautifull engine sound there

[santoichinkie]

We have engine No 5 in our test cell...awesome.

[santoichinkie]

why minus, I stated fact

[AKsProduction]

may i ask what's that sphere thing they put on at the end of the video?

[santoichinkie]

It is a diffuser to cut down turbulance

[steve45coe]

@santoichinkie GE suck man, Remember de Hudson accident. the CF6 couldnt even stand bird strikes, and the are supposly FAA certified against bird ingestion.

[aerochimp]

The GEnx-2B is actually slated to go on the latest and greatest derivative of the 747, the 747-8. The 787 uses the GEnx-1B.
