AbstractThere is an application area for turbomachines where using of gas-lubricated bearings is economically resonable in regard to rather heavy rotors. It is referring to turbogenerators with 500..2000 kW capacity value equipped with high-freguency electrogenerators. Mathematical modelling results are presented in the paper for gas flows within lubrication layer of tilting-pad hydrostatic gas bearings. Experimental data are described to demonstrate bearing strength and rigidity for discussed bearings.
Keywords:gas-lubricated bearings; hydrostatic gas bearings; tilting-pad bearings
