Defense Business Brief: Takeaways from America’s first jet engine test site

LYNN, Mass.—Rosie the robot and her automated compatriot Thomas are the stars of GE Aerospace’s automated manufacturing line at the company’s factory here. Decked in yellow, the towering machines are reminiscent of the Transformer Bumblebee’s dislocated arms. They move in concert seamlessly to collect tools, machine parts, and assemble components for the T700, which are found in Boeing’s Apache and Sikorsky’s Black Hawks, and, in the future,T408 engines for the Marine Corps’ CH-53-K King Stallion. It’s part of a multiyear $100 million investment in the plant, which is hyperfocused on upgrades—from machines to workflows—to make more engines and deliver them faster. “This was historically a bottleneck for our businesses,” Dan Martin, who manages manufacturing engineering and leads a team charged with integrating robotics and automation inLynn plant, said of the piece of the business that makes rotating parts, like cooling plates. “We had quality issues here. We had capacity issues here. The robotics piece now comes online, and these lines are no longer constrained for us.”That need to go fast will be key once the military starts putting in high-volume orders for collaborative combat aircraft, or robot wingmen for fighter jets.“We're designing from the very beginning to meet the right production,” starting with small engines, Amy Gowder, GE Aerospace's president and CEO for its defense and systems division, told reporters Monday. For example, “we did a seven-way exercise, and we're like, ‘no, we need a tack time of 100 seconds for each [screw], not an hour and a half,” for 70 screws.In addition to changing techniques and design practices, Gowder said the company is looking for suppliers that are “used to the high volumes we need.” For the F404/F414 engine, which is found in the F/A-18, “we're trying to move to a different supply base that has different commercial off-the-shelf type standards that have operated at this volume,” she said. “And when we tell them we want to go from one engine a month to 20 engines a month in like six months or a year, that doesn't phase them because they're used to handling the volumes. Only when you get to like 100 engines a month do they start to say, ‘hey, I might need some some investments or capacity to meet that.’” GE is also conducting “producibility reviews” as it brings on suppliers, she said. “So we think we designed it correctly. We think we've chosen the right types of suppliers that have the capacity and processes we need, but as they actually get the drawing and figure out how they're going to make it for the first time, we're there with them [to review] other changes before we lock in that final design.” WelcomeYou’ve reached the Defense Business Brief, where we dig into what the Pentagon buys, who they’re buying from, and why.

The Pentagon’s innovation arm tapped GE Aerospace to develop a hypersonic test bed as part of the Hypersonic and High-Cadence Airborne Testing Capabilities, or HyCAT, program. The award follows one for a prototype in 2023. The first flight is targeted for 2028.
