A recent Boeing study predicted a demand for up to 23,000 single-aisle airliners over the next 20 years. For the three engine manufacturers involved in the seven single-aisle aircraft currently in development, the business case for developing all-new engines to power them has been more than justified.
Raisbeck Engineering’s swept-blade “turbofan propellers” for the King Air 200 series are now approved in Brazil after the Brazilian National Civil Aviation Agency (ANAC) granted certification late last month.
A spokesperson for Raisbeck Engineering told AIN, “There are about 500 King Airs in Brazil alone, making it a major market for us. We hope that the swept-blade prop reenergizes our presence in the South American region and we’ll be focusing a lot of our attention on the market as it continues to grow.”
Embry-Riddle Aeronautical University in Prescott, Ariz., will incorporate five turbofan components from previously repaired engines, a donation from Snecma America Engine Services (Sames), into its aerospace and mechanical engineering programs.
The donated items (a fan shaft assembly, thrust bearing, compressor rotor shaft, fuel manifold ring and high-pressure turbine rear shaft) came from a CFM56-5A, the engine that powers single-aisle aircraft such as the Airbus A319 and A320. The components will help expand engineering students’ understanding of turbine engines.
A switch from composite to titanium for the inner walls of the thrust reversers on the Boeing 737 Max has allowed designers to increase the fan diameter in the airplane’s CFM International Leap-1B turbofans without a proportional increase in the size of the nacelle. The relatively minimal growth of the nacelle means Boeing could keep its original plans for coping with the small amount of ground clearance margin available while optimizing thrust levels, explained 737 Max program vice president and general manager Keith Leverkuhn.
The price of maintaining Rolls-Royce Spey engines, which power the Gulfstream II and III, has dropped dramatically over the last several years, according to MRO shops and operators. Gulfstream made 460 GIIs and GIIIs between 1966 and 1987, but operators increasingly are scrapping them in response to rising fuel prices and more stringent anti-noise requirements that will require the installation of hush kits or restrict operations.
More than two years after Boeing acknowledged problems with the 747-8’s flight management computer (FMC), the airplane carrying a package of improvements largely centered on the Honeywell FMC took to the air last week. Taking off from Paine Field in Everett, Washington, at 1:30 p.m. local time on May 20, the 747-8 Intercontinental flew for about four hours with the newly upgraded FMC and a performance improvement package (PIP) for its General Electric GEnx-2B turbofans.
GKN Aerospace’s acquisition of Volvo Aero is starting to bear fruit, giving the UK-based aerostructures group a significant boost in this growing market segment. This year, the addition of the Sweden-based engine systems manufacturer is expected to boost total revenues from GKN’s aerospace division by approximately $700 million, to $3.5 billion.
GE Honda Aero Engines has announced that its 2,095-pound-thrust HF120 turbofan intended initially for the HondaJet is nearing completion of certification tests and is on track for delivery of the first entry into service engines before the end of 2013. “We now have a line-of-sight for certification and we are gaining experience on the fleet,” said Terry Sharp, GE Honda Aero president. “We are gearing up for the production environment, which should come by the end of the year.”

Among the few economic forces behind the rather tepid recovery of the market segment covering small and medium-sized business jets, perhaps the most influential rests with the world’s financiers. While the large business jet segment remains buoyant due to its comparative immunity from the vagaries of liquidity availability, for the rest of the market a lack of attractive financing terms remains a serious problem, according Pratt & Whitney Canada (PWC) president John Saabas.
