The General Electric GE9X is a high-bypass turbofan developed by GE Aerospace exclusively for the Boeing 777X. It first ran on the ground in April 2016 and first flew on March 13, 2018; it powered the 777-9's maiden flight in early 2020.
The Rolls-Royce Trent XWB is a high-bypass turbofan produced by Rolls-Royce Holdings.In July 2006, the Trent XWB was selected to exclusively power the Airbus A350. [2] The first engine was run on 14 June 2010, [3] it first flew on an A380 testbed on 18 February 2012, [4] was certified in early 2013, [5] and first flew on an A350 on 14 June 2013. [6]
The 62,264–81,028 lbf (276.96–360.43 kN) engine has a bypass ratio over 10:1, a 2.85 m (112 in) fan and keeps the characteristic three-spool layout of the Trent series. The updated Trent 1000 TEN with technology from the Trent XWB and the Advance3 aims for up to 3% better fuel burn. It first ran in mid-2014, was EASA certified in July 2016 ...
It is one of three engines for the 777-200 and -200ER, and the exclusive engine of the -200LR, -300ER, and 777F. It was the largest jet engine, [3] until being surpassed in January 2020 by its successor, the 110,000 lbf (490 kN) GE9X, which has a larger fan diameter by 6 inches (15 cm). However, the GE90-115B, the most recent variant of the ...
GEnx on 747-8I prototype. As of 2016, the GEnx and the Rolls-Royce Trent 1000 were selected by Boeing following a run-off between the three big engine manufacturers. The GEnx uses some technology from the GE90 turbofan, [1] including swept composite fan blades and the 10-stage high-pressure compressor (HPC) featured in earlier variants of the engine.
The 62,264–81,028 lbf (276.96–360.43 kN) engine has a bypass ratio over 10:1, a 2.85 m (9 ft 4 in) fan and keeps the characteristic three-spool layout of the Trent series. The updated Trent 1000 TEN with technology from the Trent XWB and the Advance3 aims for up to 3% better fuel burn. It first ran in mid-2014, was EASA certified in July ...
The Rolls-Royce Trent 700 from the 1990s, with a pressure ratio of 36:1 and 3 separate compressor rotors, needs 3 rows of variable blades and 7 bleed valves. In the beginning higher pressure ratios had to be obtained with many stages because stage pressure ratios were low, about 1.16 for the J79 compressor which needed 17 stages. [ 58 ]
The competing Rolls-Royce Trent 900 was named as the lead engine for the then-named A3XX in 1996 and was initially selected by almost all A380 customers. However, the GE/PW engine increased its share of the A380 engine market to the point where, as of September 2007, it will power 47% of the super-jumbo fleet.
