Solar Atmospheres Vacuum Heat Treats Titanium Manifold for Artemis 1 Mission

November 23, 2022

For the 2014 Orion launch, NASA introduced the Launch Abort System (LAS). This large manifold housing made from 6AL-4V titanium is designed to rapidly propel astronauts away from the main rocket in case of a catastrophic explosion or any other unexpected event. Once fired, the LAS will accelerate the astronauts away from the main rocket at forces up to 10 to 15 times normal gravity (“G’s”). This critical part of the safety system was once again vacuum heat treated by Solar Atmospheres of Western PA for their most recent launch.

Test Facility Simulation Results for Aerospace Loss-of-Lubrication of Spur Gears

June 1, 2015

Prior to receiving airworthiness certification, extensive testing is required during the development of rotary wing aircraft drive systems. Many of these tests are conducted to demonstrate the drive system’s ability to operate at extreme conditions, i.e. — beyond that called for in the normal to maximum power operating range.

3-D Printing: We Ain't Seen Nothing Yet

NASA is now 3-D-printing spare parts up at the ISS (International Space Station). And in zero-gravity environments. And some of these parts are small gears and actuators, for starters. Every indication is that the list of power transmission-type parts to be converted will soon grow.

SARJ Repairs Show Promise for Space Station Solar Power

January 1, 2009

Much has happened since we last reported on the malfunctioning solar array rotary joint (SARJ) attached to the International Space Station. Space shuttle Endeavour dropped in for a two-week visit in November during which repairs were made and invaluable data collected.
