A more detailed article on this system was published in PC 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.
