The new Rolls-Royce Trent APS engine transportation stand
The Rolls-Royce Trent is a British turbofan engine, developed from earlier Trent series engines. The Trent powered the Boeing Dreamliner on its maiden flight, and on its first commercial flight. On 6 April Boeing announced that it had selected two engine partners for its new Initially, Boeing toyed with the idea of sole sourcing the powerplant for the , with GE being the most likely candidate.
However, potential customers demanded choices and Boeing relented. For the first time in commercial aviation, both engine types will have a standard interface with the aircraft, allowing any to be fitted with either a GE or Rolls-Royce engine at any time as long as the pylon is also modified. As with earlier variants of the Trent family, Rolls partnered with risk and revenue sharing partners on the Trent program.
This time there were six partners: Kawasaki Heavy Industries intermediate compressor module , Mitsubishi Heavy Industries combustor and low pressure turbine blades , Industria de Turbo Propulsores low pressure turbine , Carlton Forge Works fan case , Hamilton Sundstrand gearbox and Goodrich Corporation engine control system.
Altogether, these partners have a 35 percent stake in the program. In June , the first public engine selection was made by Air New Zealand who chose the Trent for its two firm orders. The Trent family makes extensive use of technology derived from the Trent demonstrator.
In order to fulfill Boeing's requirement for a "more-electric" engine, the Trent is a bleedless design, with power take-off from the intermediate-pressure IP spool instead of the high-pressure HP spool found in other members of the Trent family. The bypass ratio has been increased over previous variants by suitable adjustments to the core flow. A high pressure ratio along with contra-rotating the IP and HP spools improves efficiency,  and the use of more legacy components reduces the parts count to minimise maintenance costs.
A tiled combustor is featured. The initial design failed to meet the Boeing required specific fuel consumption SFC. Rolls-Royce developed an improved version of the Trent , which achieves reduced fuel burn via an improved intermediate pressure compressor, in which the aft rear stages spin at higher speeds; three blade blisks were introduced in the new compressor. Variants were certified by the EASA . Data from EASA .

The cost of such a change would require a significant operating cost difference between the two engine types to make it economical. A difference that does not exist with the engines today.
