NASA-LLIS-0438 : Lessons Learned - Voyager Photopolarimeter Subsystem (PPS) Filter & Analyzer Wheel Step Problems (~1977)
سازمان: NASA - National Aeronautics and Space Administration (NASA)
کلید واژه: Contamination , Electrical Contacts , Hardware , Parts Materials & Processes
سال: 1996
زبان: English
قیمت: 290000 تومان
Abstract:
Palladium is a particularly efficient catalyst for the formation of polymers. Palladium in the potentiometer wiper contacts on the Voyager Photopolarimeter Subsystem formed a frictional polymer that prevented the stepping of both the analyzer and filter wheels.
Catalytic material, including palladium-containing substances, should not be utilized in designs for sliding wipers, relay contacts, etc.
