The Devil Is In The Details: How GE Found A Way To Bring 3D Printing To Mass Production

Tomas Kellner
October 03, 2018

3D printing has rightfully gotten a lot of buzz because of the marvels it can do. Also known as additive manufacturing, it has opened new paths for designers to create custom shapes that were previously too expensive or downright impossible to make. The technology's potential is enormous, but GE engineer Peter Martinello offers a dose of perspective. “This is true if you have to print just one part,” he says.

Back in 2008, long before the Federal Government recently doubled down on Australian Industry Capability (AIC) requirements of suppliers to the Australian Defence Forces, GE Aviation was collaborating locally to support the safe and efficient flight of Australia’s Classic Hornets and Super Hornets.

In Alabama, 3D Printing Is Helping One Professor Teach The Engineers Of Tomorrow

Dorothy Pomerantz
September 14, 2018
Two years ago, Bart Prorok, a professor of materials engineering at Auburn University in Alabama, decided his students needed to learn about additive manufacturing, also known as 3D printing, if they were going to be prepared for the jobs of tomorrow. But buying a commercial metal additive manufacturing machine was out of the question because of the price.

A Quieter Sonic Boom: GE Is Helping NASA, Lockheed Martin Design A New Supersonic Jet

Fred Guterl
September 11, 2018
When Chuck Yeager flew NASA’s first rocket plane, the X-1, past the sound barrier for the first time in October 1947, confirmation of his feat rang out across the desert in the form of a sonic boom — the thunder caused by compression of sound waves at the bow of the plane as it reached Mach 1. In the seven decades since, the boom has remained an impediment to widespread supersonic travel, outside of the military.

Workers Wanted: Wing Walkers And All, The World’s Largest Airshow Is The Perfect Place To Look For Jet Engine Factory Prospects

Tomas Kellner

Every year at the end of July, acrobatic pilots turn the sky above Oshkosh, Wisconsin, into a special kind of canvas, their planes’ smoke flares painting it with giant loops, corkscrews and figure eights. On a recent Wednesday, a Red Bull pilot was turning somersaults with his helicopter, flying it upside-down high above the admiring crowds attending the annual EAA AirVenture Oshkosh airshow.

August 01, 2018
One of the biggest hits at this year’s Oshkosh airshow wasn’t even there. It’s been busy proving its mettle in a test chamber half a world away, on the outskirts of Prague.

One-Week Wonders: Oshkosh Volunteers Learn How To Build A Plane In Seven Days

Tomas Kellner
July 28, 2018
"Mark Johnson designs new jet engines for living, a process than can take half a decade or more. But this week he’s working around the clock inside a hangar in Oshkosh, Wisconsin, racing to build a functional plane in just seven days. “As soon as I saw the opportunity pop up, I thought about it for maybe an hour and said, ‘I'm going to go do it,’” he says. “I was excited. It was going be a new experience for me.”

You Won’t See This On Television: This Company Is Doing Extreme Makeovers For Planes

Tomas Kellner
July 27, 2018
Randy Znamenak has spent the last few decades in the aviation business, but he should really try his hand at television. In an age when makeover reality shows involving homes and restaurants as well as human bodies are all the rage, Znamenak’s job fits the bill perfectly. His company, Nextant Aerospace, takes legacy turboprop planes and jets and turns them into new flying machines.

Ladies And Gentlemen, Start Your Engines: The Greatest Airshow On Earth Takes Place This Week In Oshkosh

July 25, 2018
There’s a brass plaque hanging on a redbrick wall in downtown Oshkosh, Wisconsin, dedicated to the woodworkers who once animated this quiet midwestern town and turned it into the “sawdust capital of the world.” The sign is a nice touch, but there’s no need for Oshkosh to live in the past. The lumber mills and sawdust are mostly gone, but there’s still plenty of wood — as well as steel, aluminum, carbon fiber and other materials used for building planes — buzzing through the air, especially in summer.

Loop The Loop: This GE Engine Comes With A Twist

Kristin Kloberdanz
July 25, 2018
Over the last few years, engineers at GE Aviation have been teaching new tricks to a workhorse turboprop engine designed to power planes that can fly through the harsh Siberian winter or the hot Saharan desert. Now with an upgraded lubrication system that keeps the oil flowing even at zero-gravity conditions, the new H75-100 turboprop engine can finally have some fun. It has started out by powering the zippy Dart 550, the just-released aerobatic plane from Austria’s Diamond Aircraft that’s destined to fly the entire suite of unusual all-attitude maneuvers.
