Boeing’s confirmation in March that GE Aviation will provide the new GE9X engine to power its proposed 777X development marked the culmination of three years of preliminary work between the engine maker and the airframer in their quest to be in a position to promise a 10 percent reduction in fuel burn compared with the GE90-115B engines on the existing 777-300ER. Also promised is a 5 percent improvement in specific fuel consumption over rival widebody engines by 2020.

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.

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.

Snecma Silvercrest

Snecma appears to be giving itself more time before beginning flight-testing of its first business jet engine: the Silvercrest. But the apparent delay in what had been projected at last year’s EBACE show as a first flight in the first half of 2013 will likely have little bearing on the certification path for the new turbofan’s first applications.

Despite some vacillation on the part of airframe OEMs still studying the form their respective 90-seat turboprop might finally take, development of Pratt & Whitney Canada’s engine offering continues on what company vice president of marketing Richard Dussault called a critical path leading to expected launch next year.

GE Aviation has started assembling the first Passport development engine for the Bombardier Global 7000 and Global 8000, the company announced yesterday. Testing of the 16,500-pound-thrust turbofan is scheduled to begin in the second quarter.

In a widely unexpected move, Embraer has switched partnership alliances from GE to Pratt & Whitney with its choice of the Geared Turbofan to power the next generation of E-Jets. The decision, announced last Tuesday, gives Pratt & Whitney its fifth application for the engine line also known as the PurePower PW1000G, and leaves Boeing as the last of the four major Western airframe manufacturers not to have adopted the design.

The Silvercrest turbofan, which is to power the Cessna Longitude, was run for the first time on Snecma’s testbed in Villaroche, near Paris in September.

Snecma has started running the first Silvercrest turbofan at its Villaroche test facility near Paris, France. With 11,000 pounds of thrust, two of the units will power the Cessna Longitude super-midsize business jet.

GE Passport 20 engine

GE Aviation (Booth No. 3900) is planning on testing the first full Passport 20 engine, slated to power the Bombardier Global 7000 and 8000, in the second quarter of next year. The design of the 16,500-pound-thrust turbofan was frozen in April this year. A series of thorough safety trials is well under way.
