One of biggest aircraft engine manufacturer, Rolls-Royce is going to assembly of prototype of Trent XWB-97 for the brand new Airbus A350-1000. Trent XWB-97 is proposed to be most powerful turbofan engine ever build. The engine is planned to first run in mid-2014 and fully running in mid-2016.
In January Rolls-Royce completed the preliminary design review of Trent XWB-97 and thrust is expected around 97,000-lb. In the making of individual components of engines, the pouring of castings and creating of forgings looks very well. The only issue of all will be fuel pumps and fuel metering units, which have to larger for the big engine like Trent XWB-97.

The design of turbines is increased to get more power and run for much hotter engine. Turbine disc also will be forged from a dual microstructure disc that will provide greater stress capability toward the center of the hub. Also better creep resistance toward the tips. Another improvements is on adaptive bleed system, which is designed to turn cooling air bleed off during cruising phase. The high-pressure compressor is derived from the European new Aero Engine Core Concept program and is connected to the IP by a swan-neck duct.
The test will begin with 84,000-lb-thrust which is Trent XWB-84 and later will follow by Trent XWB-97 in order to find conditions as close as possible the real design. We will see how the greatest engine will be built by Rolls-Royce.
