General Electric is stepping up studies to provide a new engine for Boeing’s planned 777X. GE90 program manager Bill Millhaem has confirmed that the proposed GE9X turbofan will deliver 10 percent greater fuel efficiency than existing engines in the family.

The U.S. engine maker expects to achieve a first run of the high-pressure compressor rig early in 2013. The first test of the full core should be achieved by 2015.

S.S. White Technologies (Hall 4 Stand A4) has been selected to provide flexible rotary shafts for the Pratt & Whitney PW1000G engine’s nacelle. The shafts will transfer power on the variable area fan nozzle (VAFN) and synchronize actuators on the thrust reversers. The U.S. company has already provided two flexible rotary shafts for the thrust reverser rig, and previously supplied two flexible shafts for the VAFN test setup.

Honeywell has shipped the first two new TFE731-40BR engines to Bombardier for the airframer’s new Learjet 70/75 program. The new engine adds 10 percent more takeoff thrust by replacing the -20AR or -20BR engines in the Learjet 40/45 with the -40BR. “We’re turning up the wick, and putting more power to it,” said Michael Bevans, Honeywell director of technical sales, Business and General Aviation.

Pratt & Whitney Canada claims to have improved turnaround times for customers by 20 percent through a number of advances and innovations. For example, its online diagnostic tool enables customers using its PW300 turbofan, PW100 turboprop and PW200 turboshaft engine families to diagnose their engine issues quickly.

Here at the EBACE show, the engine maker is introducing a new product called flight acquisition storage transmission (FAST). This automatically acquires, stores and transmits engine and aircraft flight data for analysis for planned maintenance.
