GE Invests $4.3 Billion To Build Next-Gen Jet Engines, Open New Factories In The US

Tomas Kellner
February 15, 2017
The GE9X jet engine that GE Aviation is developing for Boeing’s next-generation wide-body passenger jet, the 777X, is wider than the body of a Boeing 737 and more powerful than America’s first manned space rocket. It’s also a big deal for the company’s business. Although the world’s largest engine isn’t scheduled to enter service until around 2020, the company already has recorded some 700 orders and commitments valued at $28 billion at list price.

Jet Engine So Large It Could Swallow A Subway Train Just Powered Through First Set Of Tests

October 26, 2016
The deep woods around Peebles, Ohio, are hiding a secret so big that it could write the next chapter in the history of aviation. At one of many test sites spread over a secluded valley, GE Aviation just completed initial ground testing of the GE9X — the largest jet engine ever built.

Fortune Magazine List Names GE As A Top World Changer

August 21, 2016
It took considerable time and investment to boost the efficiency of GE’s gigantic HA gas turbine, affectionately known as “HArriet”, by just a few percent. The company’s scientists used super materials and other technologies borrowed from jet engines to coax every last bit of performance from the machine, and gained the notice of Guinness when it hit 62 percent efficiency.

People have been making things from iron and steel for more than 3,000 years. Machines built from their alloys have landed on the moon and reached the very bottom of the ocean. But engineers such as GE Aviation’s Sanjay Correa now believe that “we’re running out of headroom in metals.”

Are You Ready For The 18-Hour Flight?

July 12, 2016
The oil embargo of 1973 was a miserable period when American towns banned Christmas lights to save electricity, billboards urged citizens to “turn off the damn lights” and filling stations dispensed gasoline by appointment only. The crisis got everyone thinking seriously about innovation and energy efficiency. One result: the massive and efficient jet engines that power the world’s longest commercial flights today.

A 10 percent increase in fuel efficiency might not sound like a lot, but in aviation, according to Wired, “engineers would step over their own mothers for a one percent bump.”

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

Tomas Kellner
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.

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.
