Reshoring OEM Makes Oilfield Pumps with U.S. Equipment
John Piehl and Tyler Mitchell All fixture and machine-assembly jobs are unique, but one Texas facility was set to manufacture gear casings with enormous dimensions - so it needed machines with fixtures, loaders, and presses that could handle big parts. Here's how they quickly setup the machinery wit...
Essentials of Test-Bed Design: Compensating for Impact in Fighter-Jet Refueling
The Navy wanted a better way to test fighter jets' aerial refueling components, because old setups didn't accurately simulate the impact between a jet's probe and the refueling drogue. So Moog CSA engineered a new test bed to more accurately simulate the forces. read more
Aerial Refueling Just Got Better with Navy''s New Testbed
When Navy jets get refueled in the sky, their tank equipment is hit with high impact forces in extreme environments. So Moog Inc. engineered this testbed to more accurately simulate the forces. It has a probe mounted to a cart that rides on a track and an actively controlled suspension system that s...
