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 · Hi Tom, I was interested in the dimensions of the nacelle, mainly the max. external diameter (which I believe is either 156in or 165in), the extreme front diameter (lip of the intake), the extreme aft diameter (cold stream exaust diameter), nacelle length and, if possible, the exaust cone dimensions.

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.

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.

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.

2017年11月9日 · 747classic wrote:AFAIK the GE9X low speed rotor is operating at a higher RPM than the GE90-115B, requiring a stronger (= heavier) fan and core engine casing to avoid an uncointaned engine (fan blade) failure, also the fan casing has a larger diameter (= extra weight.) .

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,

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).

2013年5月7日 · I recently posted a video and some pictures of the nose landing gear I made for my model 777-300ER project… many of you seemed curious about my progress and so I'd like to share a few more things!
