Boeing’s ability to use the same engine for the 737-900ER as it uses on the standard -900 undoubtedly helped the company justify its investment in the project, but that doesn’t mean the newest 737 won’t benefit from new powerplant technology.

Never before has commercial air transport come under such scrutiny for its environmental impact. While aircraft have made far more progress in terms of reducing fuel consumption and emissions per passenger carried in recent years, the relentless overall growth of air traffic has led to increasing pressure from the environmental lobby to reduce the noise and emissions produced by modern powerplants.
The General Electric/Pratt & Whitney Engine Alliance partnership was last month awarded certification of the GP7200 by the U.S. Federal Aviation Administration (FAA) and is now preparing for its first flight powering the giant Airbus A380 airliner.
Rolls-Royce has completed its first run of its Trent 1000, the engine competing with General Electric’s GEnx to power the Boeing 787.
No problems were encountered during the test, although the engine departs from tradition in being designed with a mechanical offtake for electrical power.
Pratt & Whitney’s efforts to ensure it takes pole position in the next generation of medium-sized powerplants are materializing, with several major technology programs under way aimed at ensuring its geared turbofan (GTF) demonstrator beats the competition.
Since its rejection from the Boeing 787 engine contest in April 2004 Pratt & Whitney has had to face up to a harsh new reality–that for the foreseeable future the U.S.’s most venerable engine manufacturer is effectively out of the huge market for the new medium twins from Airbus and Boeing–the A350 and 787.
In an unprecedented move, Pratt & Whitney is to manufacture components for an engine it competes with, the CFM56, in order to capitalize on the lucrative spares market for the General Electric/Snecma powerplant.
The planetary gearbox on Pratt & Whitney’s Asian Aerospace stand (A909), may not look very exciting, but it could represent the future of aircraft propulsion technology.
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.
China’s Avic I Commercial Aircraft Co. (ACAC) may carry out final assembly of the General Electric CF34-10A turbofan powering the ARJ21 regional jet if talks between the two companies bear fruit.
It would be the first time a Chinese manufacturer has taken on final assembly of a commercial engine designed in the West and would reflect China’s long-term intention to develop an aero-engine design and manufacturing capability.
