The bypass ratio is planned for 10:1. [2] The fan is housed in 134 in (340 cm) diameter case. [26] The GE9X has 16 blades, whereas the similarly sized GE90 has 22 and the smaller GEnx has 18. Having fewer fan blades reduces the engine weight, improves aerodynamic efficiency, and allows the low pressure (LP) fan and booster to spin faster to ...
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.The first engine was run on 14 June 2010, it first flew on an A380 testbed on 18 February 2012, it was certified in early 2013, and it first flew on an A350 on 14 June 2013.
By June 1999, the 8104 served as a basis for the proposed 115,000 lbf (510 kN) Trent 8115, with a scaled core by 2.5% geometrically and 5% aerodynamically and a fan enlarged from 2.8 to 3.0 m (110 to 118 in), while keeping the Trent 800 architecture: an eight-stage IP compressor and a six-stage HP compressor both driven by a single-stage ...
General Electric GE9X The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777 , with thrust ratings from 81,000 to 115,000 pounds-force (360 to 510 kilonewtons ).
The Trent 1000 is the launch engine on both initial 787 variants, the -8 with ANA and the -9 with Air New Zealand. [6] On 27 September 2007, British Airways announced the selection of the Trent 1000 to power 24 Boeing 787. On 2 August 2010, a Trent 1000 suffered an uncontained engine failure of the intermediate turbine on a test stand. [7]
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.
