2013年3月23日 · The GE90-115B delivers around 92klbf uninstalled so this has most likely been the determining factor for the TO thrust of the engine. Finally the working line at the initial cruise FL , this shows what happens with things like N1 (the Low spool = fan relative RPM ) as you throttle back the thrust, further what happens to TSFC, PR and BPR:

2016年5月14日 · GE90-115B horsepower at 100% thrust, sea level ISA Thrust 115 klb or 511545 N x 0 m/s = 0 MW GE90-115B horsepower at cruise thrust, 36089 ft ISA Thrust 16104 lb x 510 knots = 25,000 HP 71634 N x 262 m/s = 18.8 MW From GE90-115 Analysis — Tech Ops Forum | …

2007年12月14日 · I can confirm that the base GE90 (aka 94B family) and the growth GE90 (aka 115B family) have nearly identical fan case dimensions. This is by design, so that the fan stator fits in a 747F cargo door for transport.

2002年12月15日 · The GE90-115B's new blades are thicker, have a greater chord and provide an estimated extra 2,000lb thrust.

2009年9月10日 · All commercial engines have been tested successfully at considerably higher thrust than the max certified thrust while exceeding the red lines by well calculated values. For the GE90-115B that test happened to max out at 127,900 lbs. That means that one GE90-115B has survived that treatment. It doesn't mean that it is a "safe" 127,900 lbs engine.

2012年12月3日 · From ferpe's link, the published takeoff fuel flow was 4.690 kg per second. Multiply by 3600 to get kg/hr gets you 16,884 kg per hour. Convert that to pounds and you end up with about 37,144 lbs/hour takeoff flow for a GE90-115B.

2017年11月9日 · "Confirming that the GE9X is “a little heavier” than the GE90-115B, mainly because it has a larger fan diameter..." The article also outlines a new, revised testing philosophy specifically focused and optimised for the ME3's harsher running conditions: "“Our mission is to stress-test it harder, run it hotter and expose it to dust.”

GE90-94B. GE90-115B ===== Aircraft: 777-300LR (1998) Maximum Thrust: 114,900lb - - 512 kN Entry Into Service: 2003 Launch Customer: Japan Airlines (JAL) GE90-115B technical features include toughened composite fan blade material, blade-out load reduction features, increased torque fan midshaft material,

2002年11月18日 · The GE90-115B incorporated new blades that are thicker, have a greater chord and provide an estimated extra 2,000lb thrust. Fan diameter was increased from 3.12m (123in) to 3.25m (128in). The fan containment case, however, was increased by only 1.33in.

2007年6月3日 · 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).
