Satair (All 1 Stand C12) has completed a deal to be the authorized worldwide distributor in the aftermarket for certain Ducommun cable assemblies, specifically for the GE90 and CFM56 engines. Satair is wholly owned by Airbus and brings together the proprietary parts division of the OEM with the existing Satair portfolio, offering a global spares logistics service. Los Angeles-based Ducommun is a provider of engineering manufacturing services spanning aerospace, defense and industrial sectors.

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.

The Trent 900EP2 is the new-build standard for the engine that is to power the Airbus A380.

Rolls-Royce (Hall 4 Stand H3) is maintaining a continuous effort to improve in-service Trent performance, both for production engines and as retrofits. The newest version of the Trent 1000–the TEN for the Boeing 787-8,-9 and -10–is to be certified next year.

GE Aviation is preparing to begin flight tests of its new Leap-1C and Passport engines featuring nacelles developed for them by the group’s Nexcelle joint venture with Safran subsidiary Aircelle. Last month, Nexcelle delivered the first full new-generation nacelles for both programs. They are due to fly soon on the engine maker’s Boeing 787 testbed. The Leap-1C is to power Comac’s C919 narrowbody airliner, while the Passport has been selected for Bombardier’s Global 7000 and 8000 business jets.

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.

Pratt’s envisioned NGRT engine would feature an all-new compressor, a miniaturized version of P&W’s Talon combustor and possibly an eight-blade propeller.

While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with a powerplant it believes will deliver a 20-percent fuel burn improvement over existing engines in the 5,000- to 7,000-shp range by the turn of the decade. Dubbed the Next Generation Regional Turboprop (NGRT), the engine would feature an all-new compressor, a miniaturized version of Pratt & Whitney’s patented Talon combustor and (probably) an eight-blade propeller.

Pratt & Whitney expects to gain certification of the first version of the PW1100G for the Airbus A320neo during this year’s fourth quarter.

While calling extending its geared turbofan engine family’s thrust rating by another 2,000 pounds “a big deal,” Pratt & Whitney next-generation product family vice president Bob Saia sees still bigger things in the company’s future, including what he called an Advanced GTF that could rival an open-rotor design in fuel efficiency by the middle of the next decade. For now, though, Saia finds himself “busy as a bee” with the five core programs already under way at the U.S. company.

Pratt & Whitney identified the source of the failure of one of the PW1500Gs on the first Bombardier CSeries flight-test aircraft as a “seal issue” in the oil system, not the low-pressure turbine as previously indicated by Bombardier.

July 14, 2014 - 1:45am

As Bombardier readies to resume flying its CSeries CS100 test aircraft in “the coming weeks,” it remains confident in Pratt & Whitney’s ability to deliver on its commercial promises that the airplane’s PW1500G geared turbofans will perform at the level and with the reliability both companies expected.

The technology stakes are high for the GE9X engine that will power Boeing’s new 777X twinjet, but GE Aviation believes its big bet on the weight savings to be delivered by unprecedented use of composites is about to pay off. The U.S. engine maker, which currently holds orders for some 600 of the engines, is leaving nothing to chance and, with more than two years of technology maturation behind it, the company is now stepping up its test program en route to certification in 2018.
