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 ...
Trent 1000 Engine on British Airways Boeing 787-10. The Trent 1000 is a high bypass turbofan with three independent, coaxial shafts and a single annular combustor with 18 spray nozzles. The Low Pressure shaft with a swept-bladed, 2.85 m (9 ft 4 in) fan is powered by six axial turbines.
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 Trent 7000's architecture comes from the latest version of the Trent 1000, the TEN, using the A330's Trent 700 experience and technology from the Trent XWB.The 68,000–72,000 lbf (300–320 kN) engine doubles the bypass ratio and halves emitted noise compared to the Trent 700. [2]
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific.
The bypass ratio (BPR) of a turbofan engine is the ratio between the mass flow rate of the bypass stream to the mass flow rate entering the core. [1] A 10:1 bypass ratio, for example, means that 10 kg of air passes through the bypass duct for every 1 kg of air passing through the core.
The Trent 500 is essentially a scaled Trent 800, with a 2.47 m (97 in) fan with 26 unswept blades like the Trent 700. The IP and HP compressors and scaled-down by 20% from the Trent 892, while the turbines are scaled-down by 90% and are made of single crystal CMSX-4 alloy with thermal barrier coatings. Fuel burn is 1% lower because of 3D ...
