NASA Teams With Army to Analyze Helicopter Parts Failure

From left: James Van Hoose and Dr. Po Chen, engineers with Qualis Corporation inThe Materials and Processes Laboratory at NASA’s Marshall Space Flight Center has partnered with the Aviation Engineering Directorate of the U.S. Army’s Aviation and Missile Research, Development, and Engineering Center to conduct failure analysis on helicopter parts. Using Marshall’s capabilities in metallurgy, the lab analyzed aircraft components such as engine parts, swash plates, and fasteners from Army helicopters that flew in the war in Iraq and Afghanistan. It was found that the parts all experienced some type of failure with metal castings, forgings, or extrusions.

NASA Studies Benefits of Exercise for Astronauts and Public

The 20-G Centrifuge facility at NASA Ames has a radius of 29 feet and is human-rated to 12.5 G. (NASA)NASA's Ames Research Center in California has teamed with the University of Kentucky in Lexington and Vanderbilt University in Nashville, TN, to study ways to reduce adverse effects of space travel on an astronaut’s health. The study is being done on the 20-G Centrifuge at Ames, a machine that creates artificial gravity forces by spinning, and that can simulate up to 20 times the normal forces of gravity experienced on Earth.

NASA Imaging Technology Used to Fight Diabetes

This photomicrograph of a sliced rat beta cell has been processed with the modified NASA imaging technology. Insulin granules are the dark black spots surrounded by the white halo area. The colored borders around the granules are labels added to identify and classify them. (NASA/Tim McClanahan)NASA image processing technology used to explore orbital images of Earth is being modified for use in diabetes research. A team from George Washington University (Washington, DC) and Cornell University (Ithaca, NY) modified the technology, which has increased the speed of the research.
