GE test-flies the world's largest jet engine
Airliners are growing ever bigger to haul more people per flight, which means they need appropriately massive engines -- and GE Aviation is happy to oblige. It recently conducted the first test flight of the GE9X, widely billed as the world's largest jet engine. It's easy to believe the claim from a glimpse (it's as wide as a Boeing 737), but the specs back it up as well: it has a whopping 11.2ft diameter front fan that, combined with carbon fiber blades, a next-gen high-pressure compressor and a new combustor, puts out over 100,000 pounds of thrust. For comparison, some of the earliest GE90 engines aboard Boeing 777s kicked out 'just' 74,000 pounds.
GE is working on a massive 3D printer for jet engine parts
3D printing is coming of age in numerous ways. On a large scale, MIT researchers built a 50-foot-wide, 12-foot tall igloo in just 13 hours. They've also debuted the first completely 3D-printed rocket engine. On a much smaller level, our own Sean Buckley printed a little d-pad for his Nintendo Switch, while medical researchers have produced a 3D-printed patch that can heal scarred heart tissue. Now we're seeing this technology coming to the industrial world with a new laser-powered metal 3D printer from GE.
