In 2015 Rolls experienced development problems with the
As it is based on the Trent 1000, it was feared that it could share its durability problems and that could deter buyers.[7] However, Rolls-Royce's CEO Warren East said the 7000 was not affected by the Trent 1000 issues.[8]
It received its EASA
By August 2018, quantity production was challenging and in October Rolls-Royce expected 500 large engines deliveries in 2018, down from 550.[12] Rolls confirmed 10 deliveries by the end of October, below the 30 needed for 15 A330neos deliveries by year-end.[13] The A330-900 was initially cleared for 180 min ETOPS with a limitation of 500 engine cycles for the first delivery to
In 2019, Rolls-Royce delivered 106 Trent 7000s, up from eight in 2018, while it achieved a 99.9% dispatch reliability.[16]
Design
Its architecture comes from the latest version of the Trent 1000, the TEN, using the A330's Trent 700 experience and technology from the
Compared to the 20-year-older Trent 700 introduced in 1995, the Trent 7000 features a smaller fan hub and a larger fan —112 inches (2.8 m) compared to 97 inches (2.5 m). This doubles the bypass ratio from 5 to 10.[18] It has the highest bypass ratio of any Trent engine.[19] The fan has 20 blades.[20]
The
Despite the additional weight and the extra drag resulting from the wider diameter, Rolls-Royce reported
At take-off, the fan displaces up to 1.3 t (2,900 lb) of air per second, the
