FIELD: chemistry.
SUBSTANCE: present invention can be used in hydraulic systems of aviation equipment with operating temperature ranging from minus 60°C to plus 175°C. The fluid contains, in wt %: 2,6-di-tert-butyl paracresol 0.3-0.5; phenyl-α-naphthylamine 0.2-0.5; tricresyl phosphate 1-3; thermostable dioctyl sebacate 9.6-19.5; polyalphaolefins with 1.7-2.0 mm2/s viscosity at 100°C 34-44.3; polyakyl siloxane liquid with viscosity 14 - 16 mm2/s at 100°C 9.4-48.1.
EFFECT: improved thermal-oxidative stability, viscosity characteristics at sub-zero temperatures, and increased maximum operation temperature.
