the engines are getting so powerful and reliable now they dont even need 2 anymore. you may find one day that aircraft might have two engines but only one will be used and the other will just be a backup for emergencies. that could be possible i think. GE and rr have plans for a even more powerful engine than the ge90-115b.
The Airline industry always endeavour to save fuel costs. Period. So carrying a redundant engine means an extra 4-5 tonnes. I'd doubt they'd consider this idea.
@bertyUK that 4 or 5 tons you mention would be the same as having an extra engine anyway. you would save fuel by using just one engine and having an emergency backup. Who knows? Anything might be possible in the future with new designs being thought of all the time
@houshidar558 you are looking at the FAN of the engine and saying it dwarfs other engines that don't have a fan. How is that a fair comparison? What about the engine core?
@houshidar558 Yeah, The fan is not the N1 nor is it the intake. Most people don't realize this. That was my point. Of course it is an impressive engine. I have received GE factory training at their facility and have my class picture taken in front of this engine.
@MrGopherhead wow i never knew this, thanks for the info so what is the N1 in a video of a cockpit flight the pilot pointed to the N1 in his screen and said " thats the big fan up front in the engine"
@houshidar558 N1 is the low-pressure spool.In other words,the"first stage"or"large fan"at the front of the engine,and the forward set of core compressor blades spin with this.The rearmost turbine blades also spin with this N1 spool.N2 is the high-pressure spool.The rest of the core compressor blades not spun by the N1 spool are connected to the N2 spool.The forward-most turbine blades closest to the combustion process also are connected to the n2 spool. There you go: N1 = first stage/Big Fan :D
@applesweeter We are attracted to things that are different and that we shouldn't be doing and that's why we are fascinated by flying. We naturally shouldn't fly, but because of our minds we are! On a lower animal level, we know it's something special.
They're language sounds like they're talking backward it sounds kinda freaky i have a friend who can speak this language but it didn't sound like that maybe they are different languages?
Metal fan blades are both heavier and less durable than composites. I think composites are here to stay, especially with the GEnx having an entire fan assembly made completely out of carbon fiber.
RR actually had the Trent 8115 that matched the GE90-115B, but due to the exclusivity deal that GE did with Boeing, (GE willing to share part financial risk on the 777-300er), RR shelved it.
No denying the GE90 is a stunning piece of engineering!
@gcoochy. I agree. GE have resorted to composite fan blades because they can't match the weight of the Trent 1000 on the 787. But they maybe the future as they must be cheaper to produce than hollow-filled titanium. Better?
Gorgeous piece of engineering. I thank GE for this engine it took me across the Pacific and back no less than four times last year without the slightest hiccup.
If you want to get into the training to work on Aircraft & Powerplant/Engines, spend two years in training, about 6 more months to get your Federal Licenses (A&P), then spend another 3 to 5 years in work experience. It all clicks together. Aviation isn't that big a deal, there's a few simple principles most of which are Force = Pressure x Area, which make everything work. It's all relative with piston engines, jet engines, automotive and aviation. But you gotta be having fun first. lol
Developing Thrust is all about how much Mass Airflow can be pushed in Lbs/Sec.
Force-Thrust in Lbs = [Jet Nozzle Pressure in PSI] x [Jet Nozzle Cross-Sectional Area in Sq. In.]
There's two jet nozzles overlapping each other on a Turbofan Engine, Fan and Core Jet Exhaust Nozzles. The hot gas Core Jet Velocity stream is enveloped by the Fan cold air Jet Velocity stream. Their Jet Velocities are equalized by different exhaust nozzle areas. This is also why they run quieter than Turbojets.
@DraXterzor hey man im in toronto doing the aircraft maintenence engineer program, but i am intersed in closley working with the a380 and the ge90s and trent900s any tips, i have just started the program but my goal is to be working very closely with a380 i went to dubai in the emirates a380 and i seen it up close it is a beautiful machine
This is the GE90 stripped of it's engine nacelle, it needs to be this big to produce the maximum amount of thrust it needs. It is enormous and therefore is extemely powerful.
starting it up was noisy though, i mean when we got into the plane the engines where off, and then when they started them, the startup noise was unbelievable from the inside of the plane. it was so strong and it feels loud in your head.
I heard the f-35 which will have a turbofan is going to be 4x louder than an f-15. I have no idea what it sounds like, (but I know it will sounds cool) but they're already starting to fly some f-35's

Dear All,
I have some questions about psychology:
(1) Why do we love flying?
(2) Why do we like jet engines?
(3) Why do we like to see a very big jet engines?
(4) Why does the high-pitch-sound of an jet engine is so attractive to us?
THANK YOU IN ADVANCE for your creative ideas and brainstorm!!! :)

HP & NET THRUST PER ENGINE FLYING AT 500 MPH:
500 MPH = [500] x [22 /15] = 733.33 Ft/Sec
Fg = [Ms x V2] / [32.2]
V2 = [115,300 x 32.2] / [3,000] = 1,237.55 Ft/Sec Jet Velocity
Fn = [3,000] x [1,237.55 -733.33] / [32.2] = 46, 977.02 Lbt
THP = [(46,977.02) x (733.33)] / [550] = 62,635.74 HP PER ENGINE @ 500 MPH
Fg = Gross Thrust = Max. Thrust while at rest = 115,300 Lbt
Fn = [Fg - Ram Drag] = Net Thrust per Engine flying @ 500 MPH = 46,977.02 Lbt

This engine is the biggest ever jet engine to be installed on a plane its being used in two Boeing models which are the: 777-300ER and the 777-200LR
The GE90-115B fan is an advanced design made from composite materials and is the first production engine to feature swept rotor blades.
Its so massive and to be honest scary to stand beside it :)
I was lucky to fly in a 777-300ER a month ago coming from Qatar to Dubai and it was an awesome experience.
