Essentials of Test-Bed Design: Compensating for Impact in Fighter-Jet Refueling
Machine Design - Industry Applications, August 06, 2014
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
Machine Design - Industry Applications, July 28, 2014
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...
