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 engine doubles the bypass ratio to 10:1 and halves emitted noise. Pressure ratio is increased to 50:1, and it has a fan and a bleed air system. Fuel consumption is improved by 11%. Development 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 were made in Derby, further test engines and production Trent 7000 is 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 was feared that it could share its durability problems and that could deter buyers. However, 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 was then planned to be disassembled, examined 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
