Does anyone on here have any crazy amazing facts about the GE90-110/115B? We all know the thrust numbers and technical info, but what about any other cool facts. (Kinda like on Boeing's homepage with their fun facts about their aircraft.) Just a thread to break up the monotany.


We often judge others by their actions, but ourselves by our intentions.

From Wikipedia:

A fan blade from the GE90-115B has been placed on display at the Museum of Modern Art in New York City, New York.

Claims have been made that a single engine moves enough air to empty a building the size of the Madison Square Garden in one minute.

The diameter of the engine (3.43 m) and nacelle are larger than the fuselage of a Boeing 737 (3.4 m).

Hope that's a good start!

B-52s don't take off. They scare the ground away.

Stated on the Boeing Everett tour while taxiing by a B-52:

A single 777 engine has more thrust than all eight engines on the B-52 combined.

That was true for early B-52s but not for the last couple of of models, including those still in service, equipped with P&W TF-33 turbofans (military version of the JT3D on most 707s and DC-8s). I believe the TF-33 on the B-52 has about 17,000 lbs of thrust, or 136,000 lbs. for the 8 engines combined. Still not that much more than a single GE90-115B!

But technical facts are fun! GE states that at take-off power, the fan is spinning at 2552 RPM. GE also states that the GE90-115B delivers an equivalent of 145,000 hp (108,126 kW). Assuming this to mean the maximum power delivered by the fan at take off conditions, there is about 298,415 ft-lb (404,597 Nm) of torque being delivered by the LP turbine to the fan under these conditions. The LP turbine would probably need to deliver more torque than this to the LP spool, as it also needs to provide power to the booster section. IIRC, GE had to develop an new alloy for the LP shaft to withstand this phenomenal amount of torque.

Just very recently, the GE90-110/115B reached its 3 years Entry Into Service anniversary.

- 3 years of service and fleet leader has a little bit more than 3,000 cycles... that's amazingly over 1000 cycles per year average for a long ranger like 777-300ER

- 1,000,000 flight hours mark also passed, and STILL not a single IFSD or engine related rejected takeoff.

- Dispatch reliability is 99.96%.

Great engine! GEnx has alot of do to go one step further and better than this boy!
