Radiation Stability of Low-Viscosity Base Oils for Aerospace Engineering Control Systems

The results of radiation exposure on low–viscosity mineral bases for hydraulic oils for aerospace engineering control systems are reported. Isoparaffinic structures with different degrees of branching are best among the dearomatized low–viscosity oils with respect to radiation stability. Hydrogen and hydrocarbon gases are the basic components of the products of radiation decomposition of mixtures with a viscosity of 4 mm2/sec at 50°C.
