Rolls-Royce (Stand 1028) said at the Dubai Airshow 2017 that it is close to carrying out the first run of the Advance3 core demonstrator. The new engine core is designed to deliver maximum fuel efficiency and low emissions, and forms a key part of the company’s Advance and UltraFan engine designs.

“The new core architecture being tested in this demonstrator is a critical part of our stategy and will help us to deliver even better economic and environmental performance for our customers,” said Eric Schulz, Rolls-Royce president for civil aerospace.

The test program is designed to gather data on engine performance across more than 2,800 parameters.

The test engine features a high-power gearbox, designed to deliver efficiency at high bypass ratios, which earlier this year achieved 70,000 hp while on test, a new record in the aerospace industry, according to Rolls-Royce.

With the Advance3 core, UltraFan will offer a 25-percent fuel efficiency improvement compared with the first generation of Trent engines, and it is expected to be available for service in 2025.

Also at the Dubai Air Show, the UK OEM launched a new range of apps for airline pilots, "to give them better insight into their engines." The Pilot App will help pilots to monitor engines and manage fuel consumption, and will initially cover the Trent XWB, which powers the Airbus A350XWB, and the Trent 1000, which powers the Boeing 787.
