Abstract

The results of calculation and operational studies on the estimation offrictional losses in rolling bearings of air¬craft engines when operating in a medium of low-viscosity fuel liquids are presented. The friction losses in the bearing are proposed to be considered on the basis of the superposition principle as the sum of the losses in friction pairs formed by conjugations of its parts. Slip friction coefficients for real combinations offriction pairs in aviation kerosene TC-f water and synthetic oil B-3B are determined experimentally.
