Radiation-resistant gas-turbine-lubricant development during 1958 was centered around the expanded study of polyphenyl ethers and alkylated aromatic ethers. Meta-linked polyphenyl ethers (uninhibited) show promise for use in the 0 to 700 F range and at exposures up to 1 x 10/sup 11/ ergs g/sup -1/(C). Alkylated aromatic ethers (containing antioxidants) are somewhat less radiation stable, but show a useful temperature range of approximately -35 to 600 F. Alkylated diphenyl ethers and diaryl alkanes show the most promise for use in conventional hydraulic systems under irradiation conditions. In hydraulic systems which would tolerate high pour points (about 5 F) and marginal high- temperature viscosity, unsubstituted polyphenyl ethers could be used to advantage. The combination of radiation-stable fluids and modified soap (terephthalamatesl or nonsoap thickeners has resulted in greases of adequate radiation stability for anticipated ANP needs. Likewise, commercially available dry-film lubricants show adequate radiation stability for anticipated ANP applications. (auth)
