GAS-TURBINE ENGINE

摘要

FIELD: engine manufacture. SUBSTANCE: engine has stator with bearing supports provided with air cavities communicating at outlet with atmosphere and supporting rotors mounted on common shaft with compressor and turbine. Radial air cavities are made at stator inlet providing compressor communication with air cavities of shaft and bearing supports through holes in hollow shaft. Holes are spaced apart through 4-15 of shaft cavity diameter. EFFECT: improved reliability of engine due to reduced temperature and clean cooling air flowing over bearing supports. 7 dwg
