That the engine of a Boeing B777
-
@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
-
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.

@Danielyeoh5885 Almost... about 12 inches shy but yes, very large engine!

holly shit...

@houshidar558 Np mate :D
-
@ollo1982 ahh, thanks for that info!
-
@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

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.

@DraXterzor Ok then, how much oil does that tank hold at the bottom?

Boeing 767-400 thrust reverser test.by luisgustavo781,415,231 views
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.
