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 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]
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 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.
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
The Trent was based on an invention by Sir Frank Whittle. It was a Derwent Mark II turbojet engine with a cropped impeller (turbine unchanged) [ 2 ] and a reduction gearbox (designed by A A Rubbra ) connected to a five-bladed Rotol propeller .
The 280 cm (110 in) fan has 26 wide chord titanium fan blades. [10]The Trent 800 is an axial flow, high bypass turbofan with three coaxial shafts. The fan is driven by a 5-stage axial LP turbine (3300 rpm), the 8-stage IP compressor (7000 rpm) and the 6-stage HP compressor (10611 rpm) are each powered by a single stage turbine.
