Rolls-Royce has completed testing of the latest build of a research two-shaft engine core, known as “Core 3/2d,” as part of the E3E (efficiency, environment, economy) program. The core evaluation campaign ends without a previously planned endurance test, however. E3E technology forms the basis of Rolls-Royce’s Advance2 future two-shaft engine program, which targets entry into service in 2018.

GE Aviation Systems is looking to rename its integrated vehicle health monitoring system now that it is ready to see it enter service. The product has a launch application on an undisclosed business jet and is also being evaluated by prospective airline clients. “This turns unscheduled events into scheduled events and could save roughly $8 billion for the industry,” said president and CEO Lynn Bolsinger.

A composite fan blade, a real Rolls-Royce Trent 1000 high-bypass powerplant and a model of the Trent XWB being developed for the Airbus A350 are on the manufacturer’s stand here at Farnborough (Hall 4 Stand H3, and Innovation Zone) to illustrate the state of the engine maker’s art and where the company expects to go next.

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.

3-D woven composites process

The aero-acoustic geometry fan blades, fan case and several other parts of CFM International’s Leap engine series will be the first major engine application of a new technology, 3-D woven composites. The process was pioneered by Albany Engineering Composites (AEC), a U.S. company that has teamed with CFM parent company Snecma and has granted the French engine maker exclusivity for its process (for propulsion applications) for the life of the Leap program.

Pratt & Whitney Canada (P&WC) and GE Aviation are working on new-generation turboprop engines for the 90-seat regional aircraft that may be launched in the coming years. While P&WC is studying a clean-sheet design, dubbed Next-Generation Regional Turboprop (NGRT), GE is planning on a derivative of the GE38 turboshaft: the CPX38
