Wow! I just looked up what engines are powering the C5 and the article said that those had 43000 LBS of thrust - these have about 50% more!! Holy Moly, dats a lotta push!
Cheers mate... Whilst we will not lose any sleep over the intricacies of the modern Jet engine, your answer gave me more information than I knew, so on that basis, Thanks for the reply....
Would LOVE to have a plastic cutaway model of this specific engine with rotating parts! That would be a conversation piece for airline nerds worldwide!
You see, the original engine had a base-plate of prefabulated amulite, surmounted by a malleable logarithmic casing, in such a way that the two spurving bearings can run a direct line with the panametric fan...
Nice engine. Brother-in-law just retired from GE as a metalurgical engineer on their jet engines. Said admin is dumber than rocks and company is cheaper than cheap. Hated working for them but said it was a job. Would not want to fly either 747-8 or 380. To many people on board. More people, less service, less heads. Give me the 320/737.
@nrml2001 Your right GE is the world leader in turbine engines and also sells the most. Of all the A380's ordered ( 244 ) as of this date, 55% of them are ordered with the Engine Alliance engines ( a joint venture between GE & P&W )
It`s only a history aircraft from yesterday, design from 1968 and now is on total end . Remember all ex PanAm and TWA Maintenance Staff - during 1970 to 1973 problems after problems with JT9 engine , the Fuel system - the Autopilot system . Many Boeing worker , ex former Pizza or Hamburger engineer on productionline.
Actually the BA 777 was due to a heat exchanger that Rolls Royce did not design properly. The QF A380 was due to an incorrectly manufactured oil feed stub pipe. Both Rolls Royce issues. Look it up. Rolls generally makes good engines but the way they handled the Qantas incident turned me off of their engines.
BOACMach2 is right 02 JUN 2006 Boeing 767-223ER with General Electric CF6-80A2 . The HPT stage 1 disk failed from an intergranular fatigue crack because of GE's inadequate design of the CF6-80 series HPT stage 1 disk. During test the engine experienced an uncontained rupture of the high pressure turbine (HPT) stage 1 disk. Debris punctured the fuselage and fell onto adjacent runway and taxiways
747-8..... Winner, plus its better design where form meets function. Besides all major airports were designed around the 747 at the time. No need really to extend runway lengths unlike 380. Good Job Boeing.... If it aint broke than dont try to fix it, but improve on it....thats exactly what they did. Imporved.
Franciso.... como me gusta ver que si que hay alguien que, aunque mezclando idiomas, lo explica fantástico jajajajajaja. Felicitaciones... A Paco no al video, yo personamente... me quedo con mi Cessna 172 xD
Boeing has to do this to keep up with compitition of A380...I mean the 747-8 looks like a A380 in a 747.. Both are awsome planes, but boeing is still cutting edge in my opinion!
@Linkwizzard The old fuselage design you criticize is a proven workhorse, plus improved operating efficiencies and reliability come from the wing design and engines, both of which have been redesigned from the ground up for amazingly low seat-mile costs. Plus airlines know that the 747 is reliable, will fit existing airports and wont have empty seats on routes that serve 467 customers instead of 555. Airliner success is not based on what enthusasts like. Airlines operate these things.
does any one know why the N2 compressor rotors and the turbines as well as the induction fan is running in the opposite direction as the N1 compressors and turbines? Is that to avoid compressor stalls?
So, when air is pressurised by the compressor blades, heat is generated and that vaporises the water - Is that right?? Hard to believe that pressurising air increases it's temperature, and THANK YOU for your reply...
I'm not an engineer, but from what I do know, 70-80% of all the air passes through the fan and the air that passes through the compressor will be around 1,000 degrees before it reaches combustion. In a nutshell, I'm not that concerned.
Given how close so many of the major 747-400 operators are to Rolls-Royce, it was still nuts to go exclusively with GE engines. British Airways (the largest 747-400 operator) can't afford a repeat of the uproar in the UK when it went with GE engines for the earlier B777s. Every order they make without RR engines is a political issue. All but ensures the supremacy of the A380.
Why is that ?? Unfortunately , Pratt Whitney fell behind GE and Rolls Royce in commercial jet engine market but they are still the number 1 in military jet engine technology..
@05u16hep what i meant is the 747-8 is more fuel efficient the A380 the GE-90 is more fuel efficient and has more power then the RR really doesn't matter about weight
Thanks mate... Now when I see a jet engine in the wet, I'll understand why it still keeps going. You should be a lecturer with your understanding of physics...
Three of these engines cracked their mid shaft, two had never flown and the third had 1000 hours on it. So much for GE's quality. Right now they think it was caused by the assembly lubricant they used while tightening on the nut at the front of the shaft, but the NTSB says all GEnx engines must be inspected before any further flight and frequently thereafter. Everyone makes mistakes and suffers failures, if you think you are perfect you obviously never worked on anything like this.
You should ask Qantas about Rolls Royce engines reliability ...LOL. And regarding 777 ,in the last 12 months Trent 800 has had 3 IFSD whereas GE90 has had 2.....even though GE90 has 4.6 million FH compared to only 1.8 million FH for the Trent. GE90 flew 2.5 times as much over the last year and had fewer total shutdowns and the -115 had none .Source: Boeing First Quarter 2011 ETOPS report
Seems GE aren't immune from problems with their engines either. Urgent safety directives were issed by the NTSB in the light of several uncontained explosions on CF6 engines over the past few years and linked to a variety of aircraft, both Airbus and Boeing. Perhaps we should all accept that nothing is guaranteed failsafe.
If you want to argue with me, let me warn you, i am jet engine expert. And yes, composite blades, turbine feathers with holes etc.. are just minor changes, general principe has not change since WW2, and that is compressor, Comb. chamber, turbine (axial or radial). "turbo" FAN is just fan engine like turbo PROP engine, just optimized for higher speeds (500-800 kmh), it is not real Turbojet engine where you dont have fan, and 100% thrust come from rocket reaction.
So sorry stage, not etages, but gas turbine have another metric like temperatura ratio Temp exit nozzle/Temp inlet = Temp released by axial/Temp inlet * Temp combustión chamber exhaust / Temp released by axial * Temp power turbine exhaust / Temp combustión chamber * Temp exit nozzle / Temp power turbine exhaust, then temp combustión chamber is bigger tan temp released by axial, currently the exhaust of a combustión chamber reach 1000 deg to 1400 deg, the one in the axial is among 800 to 900 deg
Krelle1912 Ice crystals do form in fuel at high altitudes under special circumstances where the temperatures are much lower than expected and especially on long haul flights. However, it was the poor design of the heat exchanger that allowed the ice crystals to clog up the fuel flow thus starving the engines of fuel supply. Subsequent to the accident and demonstration of icing in the fuel line, the heat exchanger design was modified to prevent future issues of the same nature. The A380 was due to manufacturing error in the engine oil stub pipe. The walls of the pipe were thinner than specification due to improper counterbore operation. Bottom line, it is RR responsibility.
Very carefully reread my last post, I mentioned 3 things ,if you are as smart as you think you are you'll find the 3 subjects I mentioned, 2nd there is no such thing as an Me-232 there is an Me 262 with a Junkers Jumo 004 but I'm sure you already know that.
not true. old engines have 11:1 compression and the temp rises to 800 degrees. at a compression ratio double that why would 1000 degrees seem unlikely?
Depends though,the 747-8 still has the ability to land on short runways with higher weights than the 744, but the required landing distance will be more than the 744. However for short field landings,good pilots are required. However if you speak of 2500m runways then abosolutely no problem on the 748i (skilled pilot required though)
boeing + airbus combined = AMAZING
That engine looks amazing, you can really appreciate how far modern technology has come seeing this.
Wow! I just looked up what engines are powering the C5 and the article said that those had 43000 LBS of thrust - these have about 50% more!! Holy Moly, dats a lotta push!

Love it.
thanks for the vid dude
Kandungan video sangat baik, tahniah
I love this stuff
A380 is a engineering master peace the 747-8 is just a upgrade
This engine is the future, a far leap ahead of other engines in its thrust class
this is the best engine that GE produced ever !!!
Would LOVE to have a plastic cutaway model of this specific engine with rotating parts!
That would be a conversation piece for airline nerds worldwide!
Quality and Technology.
You see, the original engine had a base-plate of prefabulated amulite, surmounted by a malleable logarithmic casing, in such a way that the two spurving bearings can run a direct line with the panametric fan...

Removal propulsor module. Radical!

en mi opinión no limitará carga límite y dará 1/4 potencia devolver 2000 metro.

@iogaro
For a lot of RUclips videos - if you have realplayer installed you can directly download the video in .flv format.
Nice engine
Why is it that GE can build these engines but can't build a washer, dryer, dishwasher or refrigerator worth a damn?
I would agree, but Im biased, I work for UTC and machine some of the parts.
i luv both aircrafts but i like the Airbus A380 better than the Boeing 747, in my opinion, both aircrafts are beautiful

Are there other applications for this engine beside the 748? The latest jumbo doesn't look to be a best seller.
@averredude101
Well ok then, I would say it large enough, but yeah; they could have made the width a bit wider to 20'10"
I totally organismed 8x when i saw this
does any one know why the N2 compressor rotors and the turbines as well as the induction fan is running in the opposite direction as the N1 compressors and turbines? Is that to avoid compressor stalls?
GE's new engine is like a lego set... Just take it apart and replace it when damaged... lols
they are. They do it for military and have a small share in passenger jets.
GENX-1B, GENX-2B CNG
Equipped of A330-200, A380-900
So, when air is pressurised by the compressor blades, heat is generated and that vaporises the water - Is that right?? Hard to believe that pressurising air increases it's temperature, and THANK YOU for your reply...

free hummers
If it's not Boeing, I ain't going.
LMAO Too funny! Well said!!
2010 for the freighter version and 2011 for the passenger version
The A380 grounding was only Qantas, because its a higher rated Rolls Royce engine!
@luuko656 Absolutely.
if you try with this search in internet you can find a interesting simulation "Journey through a jet engine"
I looked at some boeing videos, some engines are made by roles royce apparently
Thanks mate... Now when I see a jet engine in the wet, I'll understand why it still keeps going. You should be a lecturer with your understanding of physics...
Dois eixos?
how does this compare with the 777 engine?
Three of these engines cracked their mid shaft, two had never flown and the third had 1000 hours on it. So much for GE's quality. Right now they think it was caused by the assembly lubricant they used while tightening on the nut at the front of the shaft, but the NTSB says all GEnx engines must be inspected before any further flight and frequently thereafter.

@averredude101
so are you saying the 747-8 should be classified as a small plane???
You should ask Qantas about Rolls Royce engines reliability ...LOL. And regarding 777 ,in the last 12 months Trent 800 has had 3 IFSD whereas GE90 has had 2.....even though GE90 has 4.6 million FH compared to only 1.8 million FH for the Trent.

Will the Trent 1000 be available on the new 747?
the most of the air passes through the fan is used for cooling only 20% or 30% is used in combustión purposes
Seems GE aren't immune from problems with their engines either. Urgent safety directives were issed by the NTSB in the light of several uncontained explosions on CF6 engines over the past few years and linked to a variety of aircraft, both Airbus and Boeing.

Cool engine, too bad I only see the Jumbo Dash 8 hauling cargo..
fail.. these rollout colors arent in service anymore, they have a new rollout color wich is pink and orange mixed together and it looks red!
So sorry stage, not etages, but gas turbine have another metric like temperatura ratio Temp exit nozzle/Temp inlet = Temp released by axial/Temp inlet * Temp combustión chamber exhaust / Temp released by axial * Temp power turbine exhaust / Temp combustión chamber * Temp exit nozzle / Temp power turbine exhaust, then temp combustión chamber is bigger tan temp released by axial, currently the exhaust of a combustión chamber reach 1000 deg to 1400 deg, the one in the axial is among 800 to 900 deg
I just have one question is this engine an in line 4 or a v6.
Perhaps a V16 because it is smooth and has a lower pitched sound than a V12
e oído este motor y es diferente
depend on cost how much passenger can it take
i like the 747 but the A-380 is in the top
And 2009 for first flight! (HOPEFULLY!)
GE engines produce more thrust so 3 stage is just a waste of time. But nice development there.
A380 was due to a broken oilpipe. B777 was Ice Crystals in fuel = not R&R's fault.
The A380 that failed was a 1:1000000 scenario.
Krelle1912 Ice crystals do form in fuel at high altitudes under special circumstances where the temperatures are much lower than expected and especially on long haul flights. However, it was the poor design of the heat exchanger that allowed the ice crystals to clog up the fuel flow thus starving the engines of fuel supply.
Subsequent to the accident and demonstration of icing in the fuel line, the heat exchanger design was modified to prevent future issues of the same nature.
The A380 was due to manufacturing error in the engine oil stub pipe. The walls of the pipe were thinner than specification due to improper counterbore operation.
Bottom line, it is RR responsibility.
en los aeropuertos del mundo
@beavertown2006 how? this is GE's design, they came up with it on their own
2 people missed the "like" button:)
boeing 747-8 is way better than a380(this is my personal feeling)
These types of engine rarely produce full thrust.
Very carefully reread my last post, I mentioned 3 things ,if you are as smart as you think you are you'll find the 3 subjects I mentioned, 2nd there is no such thing as an Me-232 there is an Me 262 with a Junkers Jumo 004 but I'm sure you already know that.
I like flying boeing 747-8 international better than a380
Higher efficiency and less out of balance torque load.
It's kind of funny. The same company that makes light bulbs and refrigerators makes jet engines for intercontinental planes.
not true. old engines have 11:1 compression and the temp rises to 800 degrees. at a compression ratio double that why would 1000 degrees seem unlikely?
Turbofan?
@biggestMetallicAfan so true lol
That's why they grounded the A380 fleet temporally right? And why a BA 777 crash landed at Heathrow? yeah......ok :P
What kind of oil does it take for the Barings and Engine?
No really ? How about Mineral oil ?
Many modern jet engines use a syntehic oil called 2380 turbo oil
@108107643 if a airport is able to land a 747 just now will it still be able to land the new one then with out extending the run way?
Depends though,the 747-8 still has the ability to land on short runways with higher weights than the 744, but the required landing distance will be more than the 744. However for short field landings,good pilots are required. However if you speak of 2500m runways then abosolutely no problem on the 748i (skilled pilot required though)
i think the airbus that had the uncontained engine failure had rolls royce engines
im not really afraid of flying--im afraid of crashing
@cycc1111 "if it aint boeing iam not going...'
Hi, where i can download this video?
@ncolinco me too !!!!!!!!!!!!!
Oh, sure. just ask the Qantas airline how well they like RR engines...
Nope Only GE NX 2-B will be used for the new boeing 747-8... Its is the upgraded version of the GE NX...
Yes I am a Rolls employee, your GE engines are not as advanced as our engines we have 3 stage compressors & Turbines. But GE are still good though :)
there is no way for have 1000 degrees in the exit of an axial compressor
@IHI4ZZx lol good idea
You Fail" the same ? " composite fan blades ,more fuel efficient ,quieter
