GE Aviation started testing its new fourth-generation composite fan blades for the new GE9X turbofan, the company announced last week. Chosen to power the new Boeing 777X, the 100,000-pound-thrust-class engine promises a 10-percent fuel burn improvement over the GE90-115B–the engine that powers the Boeing 777-300ER.

Certification testing is under way on the first Passport development engine at GE Aviation’s test facility in Peebles, Ohio. The engine, which will power the Bombardier Global 7000 and 8000, began ground testing on Monday and ran for more than three hours, reaching more than 18,000 pounds of thrust. This first full engine test launches a certification program that will include more than 4,000 ground hours and 8,000 cycles of testing. Certification is expected in 2015. Flight-testing on GE’s flying testbed is scheduled to begin next year.

GE has finished the first round of checks on all in-service and spare GEnx turbofans ahead of the September 21 publication of a U.S. Federal Aviation Administration airworthiness directive (AD) that calls for ultrasonic inspection of early-build engines’ fan midshafts every 90 days. GE has developed a field ultrasonic method to inspect the suspect area of the engines while they remain on the airplanes.

An all-new RB3025 engine concept has been created by Rolls-Royce following a Boeing request also extended to General Electric and Pratt & Whitney for a powerplant for a future 777-size aircraft in around 2020. The current 777 is powered exclusively by the GE90.

Rolls-Royce has selected a 132.5-inch diameter for the composite fan for the 99,500-pound-thrust engine, which will sport a 12:1 bypass ratio and a 62:1 overall pressure ratio that would be the highest achieved on a commercial aircraft.

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.

Italian propulsion component company Avio has made the trip to Farnborough to showcase its role in some of the engine industry’s latest and most advanced offerings.

A GE partner, Avio holds a 12-percent share in the GEnx engine (an option for the Boeing 787) and carries responsibility for the accessory drive gearbox, stator parts of the low-pressure turbine and lubrication system.
