“It All Started With QCSEE”: A Revolutionary Engine Finally Takes the Spotlight

Christine Gibson
September 22, 2023

The dawn of the jet age gave birth to the concept of the global village. Once jet engines made the jump from military fighters to civilian planes in the 1950s, commercial passenger service could carry people farther and faster than ever before. Fares dropped, ticket sales quadrupled, and by 1972 almost half of all Americans had traveled by air.

A Man On A Mission: Retired Air Force Navigator Zeroes In On Factory Improvements

Maggie Sieger
November 08, 2019

Few sights are more terrifying than a surface-to-air missile (SAM) targeting you while flying a B-1B bomber 25,000 feet over a hostile part of Iraq at 600 mph. But retired U.S. Air Force Lt. Col. William Dobbs surprised himself in 2003 by remaining preternaturally calm when he alerted his crew members that a missile launch tone had sounded. His only concession to anxiety, he acknowledges ruefully: “My voice came out several octaves higher than normal.”

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.

Are You Ready For The 18-Hour Flight?

Tomas Kellner
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.”

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.
