Rolls-Royce is preparing technologies for the next generation of business jet turbofans and the design engineers’ motto seems to be “smaller, faster, leaner.” Karsten Mühlenfeld, Rolls-Royce executive v-p of engineering and technology for civil small and medium engines, provided AIN with details on future designs that will feature swifter development cycles, near-perfect reliability and reduced acquisition costs.
The European Aviation Safety Agency has issued type certification for the higher efficiency and thrust “package C” version of Rolls-Royce’s Trent 1000 engine. The approval comes ahead of the anticipated first flight of Boeing’s 787-9 widebody. The 74,000-pound-thrust turbofan is set to power Air New Zealand’s first 787-9 when the new version of the Dreamliner family enters service next year, and it is also available for the existing 787-8.
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.
The Australian Transport Safety Bureau said the the failure of a Rolls-Royce RB211 engine on a Qantas Boeing 747-400, which occurred during climbout from San Francisco International Airport on Aug. 30, 2010, was caused by a fatigue fracture of a single-stage, low-pressure turbine blade.
Chromalloy, one of the world’s largest independent providers of advanced coatings and repairs for gas turbine engines and a manufacturer of approved engine replacement parts, this year marks its 60th anniversary with ongoing growth and a change in scenery. The company this fall will relocate its corporate headquarters from Orangeburg, New York, to Palm Beach Gardens, Florida.
U.S. energy group Solena is accelerating its efforts to establish a plant in the London area that from 2014 could be turning 500,000 metric tons of domestic waste into jet fuel each year. Its GreenSky program has already attracted its first customer in British Airways, which has committed to buying the new factory’s complete annual output as part of its goal to halve its total carbon dioxide emissions by 2050.
Rolls-Royce is putting all its cards on a new engine to power future single-aisle aircraft and told AIN that as far as it is concerned, “the numbers do not stack up” for re-engining either the Airbus A320 or Boeing 737.
Under a plan first revealed two years ago, Rolls-Royce and British Airways have invited fuel suppliers to participate in tests to evaluate alternative aviation fuels in a study to seek practical alternatives to kerosene, the current standard fuel. The two companies have requested samples for possible laboratory and rig trials and, ultimately, tests on a Rolls-Royce RB211-524G engine from a British Airways Boeing 747-400.
Gulf Air has selected the Rolls-Royce Trent 700EP turbofan to power 20 previously ordered Airbus A330 aircraft, along with a TotalCare long-term service agreement. With the spares, the order totals 44 engines for $1.5 billion. Deliveries are scheduled to start in 2012.
Safran and General Electric are stepping up activities at their newly formed nacelle joint venture with the appointment of Steve Walters as president. The Cincinnati-based alliance between Safran subsidiary Aircelle and GE’s Middle River Aircraft Systems business was launched in December 2008.
