METHOD FOR INSPECTING AND PREDICTING CONDITION OF GAS- TURBINE ENGINES PRIMARILY THOSE WITH INTERSHAFT BEARINGS

摘要

FIELD: aviation; power engineering; gas-transfer stations in gas and oil industries. SUBSTANCE: method involves periodic measurements of iron particles in lubricating oil while engine is running. In the process threshold concentration of iron particles for normal wear C_g≠ 1,8÷2,0 g/t is determined and if further growth of C_g is detected, operating time of engine to pre-failure condition (300-400 h) is evaluated. EFFECT: improved safety and in-service maintenance of engine. 8 dwg
