The Rolls-Royce Trent 1000 is a turbofan designed for the Boeing 787 Dreamliner. It powered the aircraft's entry into passenger service with All Nippon Airways on 26 October 2011. Unlike earlier airliner applications, its integration emphasised mechanical power extraction for the 787's electrically driven aircraft systems.[1]Rolls-Royce receives new approval for Trent 1000Rolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details[2]Trent 1000Rolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details
Aircraft integration
The engine uses three shafts and takes electrical-system drive power from the intermediate-pressure system. Rolls-Royce describes up to 500 kW of power extraction from each engine. This installation supports the 787's architecture without the conventional engine bleed-air supply for major aircraft services, while the fan and core continue to provide propulsive thrust.[2]Trent 1000Rolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details
A bypass ratio of approximately 10:1 and a fan around 2.8 metres in diameter characterise the design. The large bypass flow supplies most of the propulsive force. The intermediate-pressure power take-off also helps engine handling at low power, when the aircraft's electrical demand remains important despite a relatively low thrust setting.[2]Trent 1000Rolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details
Successive standards
Rolls-Royce announced EASA approval for the Package B version in December 2011, with certification to 70,000 lbf take-off thrust. Subsequent standards included Package C and Trent 1000 TEN. These developments increased the programme's capability and adapted the engine to the expanding 787 family.[1]Rolls-Royce receives new approval for Trent 1000Rolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details[3]Trading and Trent 1000 UpdateRolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details
Durability problems
In its November 2019 update, Rolls-Royce described technical problems affecting Package B, Package C and TEN engines. The company was introducing redesigns and expanding maintenance capacity and spare-engine availability to address disruption. An improved TEN high-pressure turbine blade remained a significant outstanding redesign at that time.[3]Trading and Trent 1000 UpdateRolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details
Later development
The later Trent 1000 XE standard incorporates a redesigned high-pressure turbine blade and cooling system. Rolls-Royce reports a 40 percent increase in cooling flow from that package, intended to lower blade temperature and improve service life. This gives the programme's later development a strong emphasis on durability alongside its original efficiency and aircraft-integration objectives.[2]Trent 1000Rolls-Royce · rolls-royce.com · Accessed 2026-09-13Open source details
