Textron AirLand Scorpion jet

The Textron AirLand joint venture said its Scorpion light strike and intelligence, surveillance and reconnaissance (ISR) jet has completed 50 hours of flight-tests since it first flew on December 12 last year. The prototype has flown to 30,000 feet and at 120 to 310 knots calibrated airspeed, with a maximum airspeed tested of 430 KTAS.

Scientists in the propulsion system laboratory (PSL) at NASA’s Glenn research center in Cleveland, Ohio, have developed a test facility that can recreate high-altitude engine icing, a long-awaited capability that should equip the aviation industry to tackle a poorly understood hazard.

Over the last 20 years, the aviation industry has documented more than 200 incidents in which turbofans have lost power during high-altitude flights, according to NASA.

Rolls-Royce on Wednesday revealed plans for a new generation of engine designs to replace the current Trent family. The first, called Advance, would reach the market by the end of this decade, burning at least 20 percent less fuel and emitting 20 percent less CO2 than the first generation of Trent engine. The second, dubbed UltraFan, would enter service by 2025 and use a geared design and a variable-pitch fan system capable of delivering at least a 25-percent improvement in fuel burn and emissions.

Liebherr-Aerospace recently delivered the first bleed air system for the C919 narrowbody to Chinese aircraft manufacturer Comac, the Toulouse, France-based aerosystems supplier announced on Tuesday. Comac chose Liebherr-Aerospace to develop, manufacture, qualify and certify the C919’s integrated air management sytem in 2010.

Almost 30 years on since Pratt & Whitney Canada’s PW100 engine entered service, the manufacturer has continued to invest in boosting the performance of the turboprop family with improvements such as reduced maintenance requirements.

Regional airliner rivals ATR and Bombardier may still be no closer to announcing their long-anticipated new 90-seat twin turboprops, but Pratt & Whitney Canada (P&WC) is determined to be ready with the necessary powerplant for program launches that it views as inevitable. Next month, the engine maker will resume testing of the compressor unit for its proposed New Generation Regional Turboprop engine and it expects to have all testing complete by mid-year.

The FAA is proposing to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada PT6A engines. The proposed AD was prompted by in-service events involving the perforation of engine cases as a result of the liberation of power-turbine blades and the fracture/displacement of the power-turbine containment ring.

Boeing has advised GEnx engine operators that it is revising the 787’s and the 747-8’s flight manuals to prohibit flight within 50 nm of thunderstorms that may contain ice crystals. Following Boeing’s recommendation, Japan Airlines immediately announced it would switch aircraft on two routes. From April to November, GEnx-powered aircraft suffered six engine-icing events, according to a GE statement. All aircraft landed at their planned destinations, said the engine maker, and none of the incidents involved in-flight shutdowns–only temporary thrust losses.

What turned out to be a big week for Boeing with the formal launch of its new 777X widebody also promises to be a big week for the engine that will power it, the GE9X. Dubai Airshow visitors can get a sneak preview of the 102,000-pound thrust turbofan through a new 3-D representation of the equipment at the GE Aviation exhibit (Chalet A9).

The E-Airbus will have six electric fans and one gas power unit that will act as both a turbofan and a generator.

EADS has set itself an ambitious target for its E-Thrust hybrid propulsion concept, a joint effort with British engine maker Rolls-Royce that went relatively unnoticed when it was revealed at the Paris Air Show in June. The E-Airbus, under its new moniker, is to enter into service in 2030 as a 100-seat regional aircraft.
