초록

A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing coolin...

청구항

We claim: 1. A method for cooling a bearing, comprising:flowing a fluid outwardly from a port in a compressor;locating the port, along a meridional length of a shroud line, in accordance with relationships:port location 90% to 95% of the meridional length for a pressure ratio between 1.5 and 2.0;port location 75% to 80% of the meridional length for a pressure ratio between 2.0 and 2.5;port location 65% to 70% of the meridional length for a pressure ratio between 2.5 and 3.0;port location 55% to 65% of the meridional length for a pressure ratio between 3....
