Boeing’s 787-8 is offered with both the 74,000-pound-thrust Rolls-Royce Trent 1000 engines and General Electric’s GEnx turbofans. The GEnx family has a thrust range of from 53,000 to 75-000 pounds.
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.
Airbus is producing a “final fix” to strengthen parts of the A380’s wing structure that have developed cracks on early examples of the very-large airliner. Aircraft now in production will be modified and the changes will be retrofitted to in-service aircraft. The cracks occurred on wing-rib feet that fasten skin panels to internal wing ribs.
The emergence of “new competitors in very powerful places around the world” has led Airbus to pursue new technologies as a way to differentiate itself, according to strategy and future-programs executive vice president Christian Scherer. For instance, despite the tough economic times, the European airframer is investing around $2.5 billion in environmental research-and-development work this year alone.
Cathay Pacific Airlines has confirmed its plan to replace its aging Boeing 747-400 fleet with Airbus A350-1000s in a new $4.2 billion deal signed at the Farnborough International airshow yesterday. The Hong Kong-based carrier has placed new orders for 10 aircraft, and will convert 16 existing orders for the A350-900 into the larger variant.
General Electric said yesterday that component efficiency improvements on its CF6-80E1 engine would provide up to a 1-percent improvement in fuel efficiency for Airbus’s planned extended-range A330. The airframer announced plans for the new development with an increased maximum takeoff weight at the Farnborough International airshow on Monday. The U.S. engine manufacturer expects to deliver the enhanced engine for the first 240-metric-ton A330 in 2015.
Rolls-Royce is making further performance improvements to its Trent 700 engine, which powers the Airbus A330. Technologies from the Trent 1000, Trent XWB and BR725 engines are being incorporated into this latest Trent 700 variant, increasing efficiency by at least 1 percent.
Rolls-Royce unveiled a new, more efficient 787 engine variant yesterday at its main Farnborough press briefing. The Trent 1000-TEN (Thrust Efficiency New technology) leverages new technologies from the in-development XWB engine for the Airbus A350XWB. The more efficient Trent 1000-TEN will be rated for up to 78,000 pounds of thrust, enabling it to be used as a common powerplant for all Boeing 787 variants, namely the -8, -9 and, if it launched by the U.S. aircraft manufacturer, the -10X.
Arkia Israeli Airlines has signed a purchase agreement for four Airbus A321neos here at the Farnborough International airshow. A new Airbus customer, Arkia will use its aircraft in an all-economy class configuration, seating 220 passengers. Engine selection will be announced later, Airbus said.
Increased range and payload for the Airbus A330 twin-aisle twinjet, announced by the European manufacturer here at the Farnborough International airshow yesterday, will be welcomed by Malaysia Airlines (MAS), whose brand-new A380 very large airliner also opened the week’s flying-displays.
