Boeing delivered the first 737NG powered by CFM56-7BE turbofans–a 737-800–to China Southern Airlines at Boeing Field in Seattle last week. The new engines, now standard on all new 737s, includes improvements to the high-pressure compressor, a new outlet-guide-vane diffuser, fewer high-pressure-turbine blades and an “optimized” low-pressure turbine.
A second test flight of the X-51A WaveRider has not gone according to plan. Successfully dropped from the left wing of a B-52H Stratofortress, and then accelerated to over Mach 5 by a solid rocket booster, the unmanned, scramjet-powered, hypersonic vehicle crashed in the Pacific Ocean off Point Mugu NAS, Calif. on June 13
EADS has unveiled two new futuristic “Flightpath 2050” aircraft. The Zero Emission Hyper Sonic Transport (ZEHST) would fly above the atmosphere to avoid dumping pollutants in it, except for a relatively small amount during takeoff. The descent would be a unpowered glide, apart from restarting the engines for the final approach and landing. A steep climb on takeoff would leave a relatively small noise footprint around the airport.
Boeing has added Hamilton Sundstrand to its team of suppliers on the KC-46 aerial tanker, awarding it a contract to supply its environmental-control system, electric-power generation system, emergency ram-air turbine system, fans and engine bleed-air system, engine controls and accessories, bleed-air leak detection system and the engine/APU fire detection and overheat detection system.
The first raw materials for Pratt & Whitney Canada’s new regional turboprop demonstrator have begun to arrive at the company’s Longueuil plant in Quebec as technicians prepare to assemble the compression system for the NGRT (next-generation regional turboprop).
On Monday at the Paris Air Show, HyperMach Aerospace Industries plans to unveil a “next generation” supersonic business jet (SSBJ) that can fly from Paris to New York in 1 hour 45 minutes.
GE Aviation announced this week at EBACE that its TechX engine, which Bombardier selected for its Global 7000 and Global 8000, has been rebranded as “Passport.” The first model in what Cincinnati, Ohio-based GE hopes will be a series of turbofans in the 10,000- to 20,000-pound-thrust class will produce up to 16,500 pounds of thrust for the new Global jets.
Flight tests of the first production Sukhoi Su-35S to be built by JSC KNAAPO at Komsomolsk-na-Amur began on May 5. The initial test flight from KNAAPO’s Dzemgi facility lasted around 90 minutes, and was flown by Sergei Bogdan.
Turbomeca chairman and CEO Pierre Fabre knows that for his company to grow and prosper, it is not only necessary to sell engines to helicopter manufacturers that deliver all over the world but also to allow engines to be built in countries like China. But it is naïve to think, Fabre said, that there is no risk of losing control of intellectual property when engines are manufactured by non-Turbomeca-owned entities.
The European Aviation Safety Agency (EASA) yesterday withdrew requirements for repetitive Rolls-Royce Trent 900 inspections it mandated following the uncontained failure of a Qantas Airbus A380 engine last November. The relevant airworthiness directive (AD 2010-0242R1), which applies to all examples of seven engine variants, follows “further assessment of manufacturing data and additional stress analysis.”
