The Rolls-Royce Trent 900 is a British series of turbofan engines, developed from the RB211 and is one of the family of Trent engines. It is one of the powerplant options available for the Airbus A380, along with the Engine Alliance GP7000.
In the early 1990s, Airbus had begun development of a larger competitor to the Boeing 747, an aircraft designated A3XX, which was later to be formally launched as the A380. By 1996, its definition had progressed to the extent that Rolls-Royce was able to announce that it would develop the Trent 900 to power the A380. In October 2000, the Trent 900 became the A380's launch engine when Singapore Airlines specified the engine for its order for 10 A380s; this was quickly followed by Qantas in February 2001.
Rolls-Royce has seven risk and revenue sharing partners on the Trent 900: Industria de Turbo Propulsores (low-pressure turbine), Hamilton Sundstrand (electronic engine controls), Avio S.p.A. (gearbox module), Marubeni Corporation (engine components), Volvo Aero (intermediate compressor case), Goodrich Corporation (fan casings and sensors) and Honeywell (pneumatic systems). In addition, Samsung Techwin, Kawasaki Heavy Industries and Ishikawajima-Harima Heavy Industries (IHI) are programme associates.
The Trent 900 made its maiden flight on 17 May 2004 on Airbus' A340-300 testbed, replacing the port inner CFM56-5 engine, and its final certification was granted by EASA on 29 October 2004 and the FAA on 4 December 2006. Rolls-Royce announced in October 2007 that production of the Trent 900 had been restarted after a twelve-month suspension caused by delays to the A380.
