Up In The Air: The World’s Hardest-Working Jet Engine Has Logged 91,000 Years in Flight

Tomas Kellner
June 07, 2016
How long is 91,000 years? Go back that far in the history of the earth and the Sahara was a wet and fertile plateau. It's also the cumulative amount of time that the world’s most hardest-working jet engine, the CFM56, has spent in the air since its first commercial flight on a DC-8 Super 70 passenger jet in 1981.

Comeback Kid: The Next Sound-Barrier-Busting Passenger Jet Could Be Quietly Supersonic

Tomas Kellner
May 26, 2016
The Concorde was the first and last supersonic jet in passenger service. But that claim comes with a caveat.
The plane could accelerate above the speed of sound only over the ocean. The prospect of noisy sonic booms caused by the plane crossing the sound barrier forced pilots to hold back the throttle above towns and cities after takeoff and before touchdown. “This speed limit actually made the plane much less efficient,” says Karl Wisniewski, director of advanced programs at GE Aviation. “It was designed to fly fast.”

Sir Frank Whittle, wearing a hat in the middle, is talking to GE engineers. Whittle is recognized as the inventor of the jet engine, along with Germany’s Hans von Ohain. They developed their first prototypes independently in the late 1930s. They did not meet in person until 1966. Whittle was knighted for his work on the jet engine.

The Art of Engineering: The World’s Largest Jet Engine Shows Off Composite Curves

April 28, 2016

Nick Kray is no Picasso, yet his work is on display at New York’s Museum of Modern Art. A decade ago, MoMA’s design collection picked up a composite fan blade from the GE90 jet engine that Kray helped create. The blade’s onyx black sinuous curves are pleasing to look at, but for Kray they are no longer state of the art. “We are now working on the fourth generation of that technology,” Kray says.

GE Started Testing The World’s Largest Jet Engine

April 22, 2016
How large is the world’s largest jet engine? So large that a professional basketball player would fit inside it comfortably with several feet to spare. Engineers at GE Aviation just assembled the first of these engines and put it on a test stand at the company’s massive boot camp for jet engines located in the woods near Peebles, Ohio.
It’s a giant.

February 29, 2016
Few airlines demonstrate the latest trends in air transportation better than does Indonesia’s Lion Air. The fast-growing carrier opened for business in 2000, flying to domestic destinations and nearby foreign airports in Singapore and Vietnam. Today, its fleet consists almost entirely of single-aisle aircraft like the Airbus A320 and Boeing 737, with hundreds of the next-generation versions of the planes on order.

The latest-generation Boeing 737 MAX, powered by a pair of advanced LEAP-1B engines, made its maiden flight last Friday in Seattle. The flight lasted 2 hours and 47 minutes. “The flight was a success,” said Captain Ed Wilson, chief pilot for the 737 MAX program. “The 737 MAX just felt right in flight, giving us complete confidence that this airplane will meet our customers’ expectations.”

Sun, Sand and Airplanes: The Best of 2015 Dubai Airshow

Tomas Kellner
November 19, 2015
It takes more than an hour to drive from downtown Dubai to Al Maktoum International Airport, the site of the city’s biannual air show. The runways are still surrounded by red desert sand. But like anything in this booming business capital of the United Arab Emirates, there are already plans to transform the airport into a major transportation hub surrounded by gleaming homes, canals, broad roads and cavernous warehouses.

The World’s Largest Passenger Plane and Other Highlights from Day One at Dubai Air Show

Tomas Kellner
November 08, 2015
The 2015 Dubai Air Show opened for business on Sunday. Cities in the United Arab Emirates like Dubai and Abu Dhabi have become major aviation hubs over the last two decades and carriers based in the Middle East such as Emirates, Etihad and Qatar Airways have become powerful global players. As a result, the Dubai Air Show, which is held every two years at the Al Makhtoum International Airport located in a desert just outside the city, has become a major industry trade event on par with the Paris and Farnborough airshows.

Up, Up and Away: GE’s Billion Dollar Bet on Ceramic Super Material is Taking Off

July 13, 2015
People have been using ceramics for millennia, but the material’s practical applications have been mostly confined to the kitchen. “When you hit it, it fails catastrophically,” says Krishan Luthra, chief scientist for manufacturing and materials technologies at GE Global Research (GRC) in New York.
