NESC Technical Update Portrait of Andrew Ring

Each year, the NESC produces the NESC Technical Update, which highlights two or three individuals from each Center and includes assessments throughout the year. Because of the critical contributions to the NESC mission this year, Rob Jankovsky, NESC Chief Engineer at GRC, chose two individuals to be highlighted. This year, it is Andrew Ring and Michael Cooper. Mr. Ring, pictured here, performs stress and fatigue testing on all manner of materials in various environments and research on jet engine materials, looking for ways to increase the performance and safety of turbine blades and disks. Several NESC assessments have benefited from his expertise, most recently in understanding crack initiation and propagation in the aluminum-magnesium alloys that make up the modules of the ISS. He has also used image processing techniques to quantify the variables in parachute energy modulator production and performance and investigate flaws in the composite weave of overwrapped pressure vessels.
