Abstract

There is an area of applications of turbomachines where use of gas-lubricated bearings is economically expedient at rather heavy rotors. It is a question of turbogenerators capacity of 500—2000 kw with high-frequency electrogenerators. In article results of designing and experimental researches of gas bearings of a turbogenerator by capacity of 1000 kw are presented.
