The objective of this program is to gather data that will permit the Air Force to assess the long term storage characteristics of water, particularly with regard to formation of particulate matter, so that the feasibility of long-term storage of water for use as a transpiration coolant can be determined. Five metallic materials of construction are included in the program 304 stainless steel, A-286 aged steel, 17-4 aged stainless steel, Inconel 718 aged, 6Al-4V titanium STA. Two types of water are used in the program oxygen-saturated, deionized, filtered, and oxygen-free, deionized, filtered. Five-year storage tests have been initiated in 304 and 17-4pH stainless steels, A-286 steel, Inconel 718, and 6Al-4V titanium STA containers using the filtered, deionized waters. Evaluation of water and containers stored for thirty months and thirty-six months has been completed. The data show that both oxygen-saturated and oxygen-free water can be stored in appropriate metal containers for the selected time periods without detrimental particulate matter formation or significant changes in the quality of the water. It is in excellent condition for transpiration coolant purposes. Author
