Two Indian airlines have between them chosen General Electric CF6-80E1, GEnx and GE90-115B engines worth more than $2.5 billion to power new Boeing aircraft while a third has opted for GE/Snecma CFM56-5Bs to power its new Airbus A320s.
General Electric GEnx
Since Snecma dropped the idea of taking a share in General Electric’s GEnx turbofan program the two long-time partners now find themselves competing in the regional jet engine arena.
General Electric (Hall 4 Stand B7) expects its revenues to grow to a record $12.8 billion in 2006–almost 8 percent more than last year. The U.S. engine maker said here that services are driving the increase.
Sales continue to be brisk, with 1,600 CFM56 orders last year and an expectation for approximately as many this year. Meanwhile, the order book for the GEnx has swelled to almost 600 engines.
Airbus’ confirmation that it is to go ahead with the A350 XWB, requiring much higher thrust engines than the original A350, has put the cat among the pigeons in the U.S. engine industry, with General Electric and Pratt & Whitney apparently poles apart on what they will offer.
CFM International predicts a huge demand over the next 20 years for up to 30,000 engines to power single-aisle aircraft as China, India, Latin America and Russia increase their fleet densities to the levels of western countries.
Volvo Aero has delivered a number of post-certification enhancements to the RM12 twin turboshaft engine that powers the Saab Gripen. Some of these have been adopted by General Electric, whose F404 was adapted by Volvo for the single-engine Swedish fighter. The company said further improvements are possible, although its main emphasis is on developing lighter weight components for commercial airliner powerplants.
GE Honda Aero Engines recently completed component and engine core tests to validate several performance enhancements for its in-development 1,700-pound-thrust HF118 turbofan. These refinements have already resulted in a 4-percent improvement in specific fuel consumption and an 8-percent weight reduction.
