Rolls-Royce is making progress in the development of its next generation of Trent engines with the completion of testing of the composite carbon/titanium (CTi) fan systems for its Advance and Ultrafan turbofan designs. The CTi was tested at the engine maker’s John C.

The engineering team for GE Aviation’s new GE9X turbofan has completed development of the new carbon fiber composite material that will allow the powerplant for Boeing’s new 777X airliner to use fewer, thinner fan blades. Combined with the use of new composite case technology developed for the GEnx program, the engine will be around 1,000 pounds lighter than its predecessor.
Pratt & Whitney and Alcoa recently have revealed that the fan blades of the PW1000G family of geared turbofans will consist mainly of aluminum alloy–an industry first.
Eaton has been selected by Rolls-Royce to continue providing its engine build-up for another Trent engine program, the Trent XWB-97. The 97,000 pound-thrust turbofan will power the new Airbus A350-1000 platform.
Pratt & Whitney on Sunday announced that is has managed to reduce fuel burn on the PW1100G-JM for the A320neo family by another 2 percent. Dubbed the PurePower Engine Advantage, the enhancement centers on improved aerodynamics and cooling.
Rolls-Royce here announced the first run of the Trent XWB-97 turbofan on Tuesday. Selected as the sole engine for the higher-thrust version for the Airbus A350-1000, The 97,000-lb-thrust Trent XWB-97 will begin test flights in 2016. Entry into service is pegged for 2017. The turbofan’s increased thrust is obtained by a combination of new high-temperature turbine technology, a larger core and advanced fan aerodynamics, Rolls-Royce (here at Hall 4 Stand H3) said.
Pratt & Whitney has enlisted IBM to improve the engine fleet management and health “solutions” the engine company offers its customers. Pratt, with IBM’s help, plans to broaden its current engine performance monitoring capabilities.
Unison Industries (Hall 4 Stand C14) has launched a new high-energy, high-temperature turbine engine ignition system designed to meet the “growing trend of climbing engine temperatures and combustion pressures.”
The Acclimate ignition system features solid-state electronics, with exciter performance that can vary depending on specific combustion and environmental requirements, according to Unison. This helps optimize ignition performance and overall system life, the company added.
Firth Rixson (Hall 5 Stand G20) has signed a 10-year agreement with United Technologies (UTC) to supply engine and system components. The components will be part of Pratt & Whitney PurePower engines as well as systems, such as landing gear, on the Airbus A320 and Boeing 787. The agreement is valued at $1 billion.
The Engine Alliance, a 50-50 joint venture of GE and Pratt & Whitney, has received EASA approval for two new thrust ratings for the GP7200 turbofan engine, one of the two engines available to power the Airbus A380. The new ratings bring the GP7200 to four thrust rating configurations.
