GE’s Passport engine marks the commercial debut of ceramic-matrix composite (CMC) material usage for harsh environment parts such as the mixer and center body assemblies. In total it uses 15 CMC parts for a weight savings of more than 40 pounds per engine.

Development is progressing on schedule for GE’s Passport 20 engine, which is scheduled for certification in 2015 and is expected to enter service in 2016 on Bombardier’s Global 7000 and 8000 ultra-long-range twinjets.

While GE has earned renown for its military and commercial engines, until recently its experience in the business aviation arena had been limited to the CF34, which has powered Bombardier’s large-cabin Challengers for the past 30 years (as well as the airframer’s CRJs and Embraer’s ERJ regional jets).

With defense budget cuts starting to bite, GKN Aerospace (Chalets (B) 73, Hall 2b Stand F140) is stepping up its efforts to reduce dependence on military business. At a recent press briefing, the UK-based group’s CEO Marcus Bryson predicted that in 2013 almost 70 percent of revenues are likely to come from civil orders, with Airbus remaining its largest customer (accounting for 32 percent of revenues in 2012).

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.

GE turbofan

General Electric is preparing its new Passport engine for a first test run next month. Intended to power the Bombardier Global 7000 and 8000 jets, the Passport 20 is scheduled for certification in 2015. Assembly of the first engine began in March, and the low-pressure turbine was installed last week. The 52-inch fan section, one of five blisk (single-piece blade disk) stages, is fitted next, followed by the composite fan case.

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.

Rolls-Royce has completed testing of the latest build of a research two-shaft engine core, known as “Core 3/2d,” as part of the E3E (efficiency, environment, economy) program. The core evaluation campaign ends without a previously planned endurance test, however. E3E technology forms the basis of Rolls-Royce’s Advance2 future two-shaft engine program, which targets entry into service in 2018.

GE Aviation has frozen the design of its 16,500-pound-thrust GE Passport 20 engine, which will power the Bombardier Global 7000 and 8000 business jets, the company announced at EBACE yesterday. Consequently, the GE engine has entered the detailed design phase. “Component fabrication will begin soon,” it said, “leading to the start of assembly of the first full engine by year-end.”
