context_page_description: The Rolls-Royce Trent 7000 is a high-bypass turbofan engine produced by Rolls-Royce, an iteration of the Trent family powering exclusively the Airbus A330neo.
  Announced on 14 July 2014, it first ran on 27 November 2015.
  It made its first flight on 19 October 2017 aboard on the A330neo.
  It received its EASA type certification on 20 July 2018 as a Trent 1000 variant.
  It was first delivered on 26 November,
  and was cleared for ETOPS 330 by 20 December.
  Compared to the A330's Trent 700, the 68,000–72,000 lbf engine doubles the bypass ratio to 10:1 and halves emitted noise. Pressure ratio is increased to 50:1, and it has a 112 in fan and a bleed air system.
  Fuel consumption is improved by 11%.
context_section_description: Announced on 14 July 2014 at the Farnborough Airshow, the Trent 7000 is the exclusive engine for the Airbus A330neo, succeeding the Trent 700 used for the Airbus A330.
  It first ran on 27 November 2015 on a test bed in Derby.
  Although the first two test engines will be made in Derby, further test engines and production Trent 7000 will be assembled in the Rolls-Royce Singapore facility.
  In 2015 Rolls experienced development problems with the Trent 1000 TEN, and had to involve extra resources to support the on-time March 2017 787-10 maiden flight but it led to delaying the Trent 7000.
  The first pair of engines were shipped to Airbus in June 2017.
  It made its first flight on 19 October 2017 aboard its A330neo application, directly after ground testing which included altitude, icing, cross-wind, noise and cyclic testing in USA, and endurance, operability and functional performance testing in UK.
  As it is based on the Trent 1000, it could share its durability problems and that could deter buyers, fixes should be available six months after the plane is introduced in summer 2018. Rolls-Royce's CEO Warren East said the 7000 was not affected by the Trent 1000 issues.
  It received its EASA type certification on 20 July 2018.
  It is certified as a Trent 1000 variant.
  This was delayed from the initially planned first quarter of 2017.
  At the time, ETOPS testing was halfway through as 3,000 engine cycles are planned, to be completed by early August.
  The engine should then be stripped and reported by the end of September, for an ETOPS certification in time for the year-end introduction.
  By August 2018, quantity production was challenging and in October Rolls-Royce expected 500 large engines deliveries in 2018, down from 550.
  Rolls confirmed 10 deliveries by the end of October, below the 30 needed for 15 A330neos deliveries by year-end.
  The A330-900 was initially cleared for 180 min ETOPS with a limitation of 500 engine cycles for the first delivery to TAP Portugal
  on 26 November.
  Full ETOPS requires an EASA approval plan with a 3,000 cycles validation test plus three simulated diversions followed by disassembly and examination before the end of December.
  ETOPS 330 was secured by 20 December.
  In 2019, Rolls-Royce delivered 106 Trent 7000s, up from eight in 2018, while it achieved a 99.9% dispatch reliability.
