The FAA is adopting a new airworthiness directive for all Pratt & Whitney Canada PT6A-114 and PT6A-114A turboprop engines. It requires initial and repetitive borescope inspection of compressor turbine blades (CT), and the removal from service of blades that fail inspection. This AD was prompted by several incidents of CT blade failure, causing power loss and engine failure. The purpose of the AD is to prevent failure of CT blades, which could result in damage to the engine and the airplane.

Bombardier confirmed on Friday that the modified Pratt & Whitney PW1524G engines for the CSeries flight-test vehicles have successfully completed the testing required for return to flight test and that the second test vehicle (FTV2) will return to the air this month.

Rolls-Royce is making progress in the development of its next generation of Trent engines with the completion of testing of the composite carbon/titanium (CTi) fan systems for its Advance and Ultrafan turbofan designs. The CTi was tested at the engine maker’s John C.

The 2014 Farnborough International Airshow (July 14-20) was a dynamic and captivating edition of the long-running biennial event–packed with high-octane sales activity, novelty and a touch of controversy. As of press time, the show was on track to surpass all the main metrics for the 2012 event, with more than twice the volume of announced sales; more than 100,000 visitors on the five trade days; and approximately 1,500 exhibitors (of which 26 percent were newcomers and 15 percent had expanded their presence).

Eaton has been selected by Rolls-Royce to continue providing its engine build-up for another Trent engine program, the Trent XWB-97. The 97,000 pound-thrust turbofan will power the new Airbus A350-1000 platform.

Pratt & Whitney on Sunday announced that is has managed to reduce fuel burn on the PW1100G-JM for the A320neo family by another 2 percent. Dubbed the PurePower Engine Advantage, the enhancement centers on improved aerodynamics and cooling.

The Engine Alliance, a 50-50 joint venture of GE and Pratt & Whitney, has received EASA approval for two new thrust ratings for the GP7200 turbofan engine, one of the two engines available to power the Airbus A380. The new ratings bring the GP7200 to four thrust rating configurations.

The Bauhaus Luftfahrt aerospace think-tank in May unveiled a concept for a “propulsive fuselage” aircraft, opening a new possibility for fuel burn reduction. It is part of a European Union-funded project in cooperation with a number of research centers, as well as MTU Aero Engines and Airbus Group Innovations (OE13). The latter company is also studying a hybrid-power regional airliner with Rolls-Royce (Hall 4 Stand H3). Meanwhile, it is flying a hybrid-lift quadcopter demonstrator for unmanned military and civil missions, the Quadcruiser.

Titanium-aluminide low-pressure turbine blades and proposed cooling arrangements on Rolls-Royce’s proposed future UltraFan engine may owe much to the RB3025 powerplant unsuccessfully offered to power the Boeing 777X. For example, the RB3025 featured a “vortex amplifier” to simplify turbine-blade cooling with HPC air.

New engines planned by Rolls-Royce (R-R) reflect recent powerplant trends, including steadily increasing propulsive efficiency obtained with larger-diameter fans, higher bypass ratios and smaller engine cores. The engines could power updated contemporary widebody platforms, with R-R civil large engines president Eric Schulz confirming “very live” discussions with Airbus. “If it decides to re-engine the A330 or A380, we will be here to provide support,” he said during a pre-show briefing.
