DEVELOPMENT OF GAS-LUBRICATED BEARINGS FOR CLOSED-CYCLE GAS-TURBINE ROTORS

Abstract

The development is reviewed of gas bearings for a closed-cycle gas-turbine rotor. Design and experimental data are given showing the problems involved in the application of these bearings. The journal bearings and the thrust bearing developed for the rotor are externally-pressurized without tilting pads. Each bearing surface is divided into three equal segments by appropriate grooving. Full loads were successfully carried by the bearings under non-rotational tests. The gas bearings operate at the same speed and with the same loads as the original oil-lubricated bearings and they fit into the space originally allocated to the oil bearings. (Author)
