Electric cars have become common, but building a commercial electric plane is a different story. Just ask Mohamed Ali, vice president for engineering at GE Aerospace. “Electric motors behave very differently at altitudes above 10,000 feet,” he says. “They are susceptible to plasma arcing, for example, and much more difficult to manage.”
With the summer holiday season underway, air travel has bounced back from its lockdown doldrums. But so has the awareness of commercial aviation’s impact on the climate.
Airlines and aircraft and engine manufacturers want to be part of the conversation.
The weather was mostly fair on April 24, 1982, when a Delta Air Lines plane flew on a routine flight from Atlanta to Savannah, Georgia. It was hardly routine, however, for CFM International, a 50-50 joint company between GE and Safran Aircraft Engines. That flight, on a McDonnell Douglas DC-8-71 aircraft, marked the first commercial use of a CFM engine, the CFM56-2.
Alex Hills developed a passion for 3D printing like most hobbyists: He bought a printer and began “tinkering around” with some simple print builds.
A decade ago, Hills, who works as a test hardware engineer at GE Aviation, printed his first generic jet engine design from plans he found online. “It was a real simple model that spun with some bearings,” he says. “I thought it was cool and printed another one that I put on my desk.”
Images sent back from NASA’s James Webb Space Telescope last week not only stunned the world visually; they changed the way humans think about the universe. But not every paradigm-shifting NASA project takes place so far away. Much closer to home, the agency is doing groundbreaking and essential work on more sustainable aviation, working with partners like GE to develop quieter, safer and more efficient technologies that promise to change the future of commercial air travel.
It’s been four years since aviation fans, industry executives, aerospace engineers and investors last descended on the local airport in Farnborough, a quiet town about an hour southwest of London. Normally, the Farnborough International Airshow takes place every two years, alternating with the Paris Air Show. Together, they are the focal point for the aerospace industry. The pandemic disrupted this rhythm, but starting Monday the Farnborough show is back on track.
It’s been a week splashed with sunshine at the Farnborough International Airshow — an unusual sight for England in July — but GE Aviation still made it rain. The GE unit that makes aircraft engines, plane components, avionics and other aerospace technology said it and its partner, CFM International, have won orders valued at more than $22 billion at list price.
