Push-back tugs and taxiing aircraft with engines powered up may well, in a few years, be seen as remnants of the past. Two exhibitors here at the Singapore Airshow are studying electric motors that would drive the aircraft’s wheels on the ground.
GE Aviation and Rolls-Royce ended their self-funded development of an alternative engine for the F-35, bowing to Pentagon opposition and looming, deep reductions in U.S. defense spending.
CFM International is ramping up the production of its CFM56 turbofan engines, driven by a record backlog and helped by new production methods. In 2010, the GE-Snecma joint venture signed 1,584 orders, and its current backlog now stands at a record 7,000-plus engines.
Hawker Beechcraft Global Customer Support will make available factory-completed Hawker 400XPR and 800XPR business jets, the company announced here in Dubai. Through the program, GCS plans to help customers locate and buy airframes for installation of XPR program updates and any other customer-specific options.
The announcement of the new joint venture between Rolls-Royce and Pratt & Whitney on mid-sized engines was hardly a statement of marriage, but the vows made by the two aero-engine giants on 12 October nevertheless secure their long-term future in the huge market for mid-sized aero-engines up to 2030.
CFM International is busy developing the Boeing 737 MAX’s version of its Leap turbofan and is zeroing in on specifications. Critically, the Leap-1B will have a fan diameter somewhere between the current CFM56-7’s 61 inches and the Leap-1A’s (for the Airbus A320neo) 78 inches.
International Aero Engines (IAE) has delivered its 1,000th V2500 SelectOne turbofan. Only three years after the upgrade was first introduced, the group shipped engine V16000 from Rolls-Royce Dahlewitz to Indian low-fare carrier IndiGo.
China has ordered 250 AI-222-25F turbofans from the Ukraine to power production versions of the Hongdu L-15 advanced jet trainer.
The National Research Council of Canada (NRC) has commissioned a wind tunnel to help aircraft manufacturers measure the noise levels generated by aircraft landing gear. Industry historically has focused on measuring and reducing the noise generated only by engines.
Turbomeca plans to reduce the specific fuel consumption (SFC) of its turboshaft engines by 37 percent by 2030, and at the Helitech 2011 show discussed the strategies it is implementing to accomplish that change. While the company plans to make changes to the engine machinery, it expects much of the reduction to come from engine-airframe integration and new practices that make more efficient use of the engine.
