Trent 7000

Visão geral

The Trent 7000 é a planta motriz construída especificamente pela Rolls-Royce para o Airbus A330neo family, combining the advanced Trent XWB core with the low-pressure architecture of the Trent 1000-TEN that powers the Boeing 787. This technology fusion strategy — sem precedentes in Rolls-Royce's history — allowed the Trent 7000 to achieve aproximadamente 25% better fuel economy than the Trent 700 que substitui on the A330, while minimizing development cost and risk by leveraging proven sub-systems from two mature Trent variants already in airline service. The result is the world's most efficient engine in the 300 kN thrust class at its entrada em serviço in 2018.

The Trent 7000 is the motor exclusivo for the A330neo — Rolls-Royce secured fonte única status against competition from GE Aerospace's CF6-80E1 and Pratt & Whitney's PW4000. The 112-inch (2.85 m) three-shaft fan delivers a 10:1 razão de bypass, up from 5:1 on the Trent 700, enabling the dramatic eficiência de combustível gain. Like all Trent engines, the three-shaft configuration provides separate spool speeds for the fan, IP compressor, and HP compressor, allowing optimal efficiency across the engine's operating range. The Trent 7000 retains the ar sangrado system required by the A330neo's conventional (non-totalmente elétrica) pneumatic architecture, unlike the no-bleed GEnx-1B on the 787.

Especificações técnicas

Variantes

The Trent 7000 is produced in two primary configurations aligned to the two A330neo variants. The Trent 7000-72 (72,000 lbf) is optimized for the lighter A330-900neo, the larger and more popular of the two A330neo variants. The Trent 7000-68 (68,000 lbf) powers the smaller A330-800neo. Unlike the Trent XWB which required a fundamentally different -97 variant for the A350-1000's thrust increase, the Trent 7000's two variants differ primarily in FADEC calibration and minor turbine settings — a reflection of the relatively modest thrust difference between the two A330neo variants and their shared structural baseline. Both variants are maintained under Rolls-Royce's TotalCare power-by-the-hour service agreements standard across the Trent family.

Aplicações em aeronaves

• Airbus A330-800neo: Trent 7000-68 (68,000 lbf) — A330neo mais curto, competindo com 787-8 on thin longa distância routes
• Airbus A330-900neo: Trent 7000-72 (72,000 lbf) — A330neo mais longo, variante mais vendida, competindo com 787-9

História do desenvolvimento

Rolls-Royce launched the Trent 7000 program in 2014 when Airbus confirmed the A330neo, and Rolls-Royce was selected as the motor exclusivo supplier. The development strategy of combining Trent XWB core technology with the Trent 1000-TEN LP system proved a rapid development path: the first Trent 7000 test ran in April 2016 — just 24 months after program launch. EASA certification was achieved in October 2017, followed by FAA certification in November 2017. TAP Air Portugal launched A330-900neo serviço comercial powered by the Trent 7000 in December 2018, becoming the first operator. The program benefited enormously from the mature component supply chains already established for both Trent XWB and Trent 1000 production. No entanto, the A330neo's market position proved more challenging than anticipated: the 787 had already captured many of the A330's traditional markets, and only 340+ A330neo orders had been placed as of 2024. The Trent 7000 thus has a smaller installed base than its Trent XWB and Trent 1000 siblings, though it forms a critical part of Rolls-Royce's fuselagem larga pós-venda portfolio alongside those engines.
