In order to verify the atomic oxygen durability of the ISS's solar arrays, this paper presents the results of functional testing of an actual solar array validation coupon. The validation coupon was exposed to a directed atomic oxygen beam with sweeping arrival while under normal tensioning.
Atomic Oxygen Exposure of Polyimide Foam for International …
2006年2月1日 · Onorbit photos of the International Space Station (ISS) solar array blanket box foam pad assembly indicate degradation of the Kapton film covering the foam, leading to atomic oxygen (AO) exposure of the foam.
ATOMIC OXYGEN EXPOSURE OF POLYIMIDE FOAM FOR INTERNATIONAL SPACE STATION SOLAR ARRAY WING BLANKET BOX 1. INTRODUCTION Solar arrays were del vered to the International Space Station (ISS) and deployed dur ng Flight 4A in November 2000. Photographs taken during Shuttle rendezvous and flyarounds have shown
polymers on ISS are collectively called the MISSE PEACE Polymers. The objective of the MISSE PEACE Polymers experiment is to accurately determine the atomic oxygen (AO) erosion yield of a wide variety of polymeric materials. The polymers range from those commonly used for spacecraft applications, such as
The Glenn MISSE experiments address atomic oxygen (AO) effects such as erosion and undercutting of polymers, AO scattering, stress effects on AO erosion, and in-situ AO fluence monitoring.
Atomic Oxygen Durability Testing of an International Space Station ...
Exposure to atomic oxygen and intermittent tensioning of the solar array were conducted to verify the solar array’s durability to low Earth orbital atomic oxygen and to the docking threat of plume loading, both of which are anticipated over its expected mission life of fifteen years.
