AI magazine called "An Expert System for Aerospace".
NASA's Contamination Control Engineering Design Guidelines
Expert System, was developed by Rockwell International's Space Systems
Division. Its objective is to educate individuals on the fundamentals
of the contamination control process, and to serve as an interactive
guide to assist with quantifying contamination requirements for
sensitive surfaces, and predicting expected end of life contamination
levels.
The tool enables the user to quantify molecular and particulate
contamination requirements for solar arrays, thermal control surfaces,
or optical sensors. The tool will also enable predictions of end
of life levels, so that on orbit performance may be verified and
critical ground/on orbit contamination control procedures may be
identified. The tool is interactive in that the user is prompted
to input various quantifiable parameters that will tailor the end
result to a specific application.
