Abstract : The objective of this program is to gather data that will permit the Air Force to assess the long-term storage characteristics of water with respect to biological grwoth, galvanic corrosion, and changes in composition of the water, so that the feasibility of long-term storage of water for use as a transpiration coolant can be determined. Eleven metallic and twelve nonmetallic materials are investigated. Basic fluid/material compatibility tests, galvanic couple measurements, biological growth tests, and long-term storage tests are carried out. Two types of water are used. Oxygen-saturated, deionized, filtered and oxygen-free, deionized, filtered. An extensive literature survey and critical review are conducted in conjunction with formulating the experimental portion of the program. In addition, a complete analysis is made on a LAR coolant tank in which water had been stored for 2.5 years. (Author, modified-PL)
