Load distribution system for gas turbine engine

摘要

There is provided an axial bearing load distribution system (20) for a gas turbine engine of the type having a low pressure rotor (21) supported by axial bearings (22,24). The system comprises a line (30) having an inlet end positioned in a highpressure compressor gas path downstream of any compressor stage provided with a variable geometry. The line (30) is adapted to sense static pressure in the highpressure compressor gas path. The line (30) has an outlet end producing the static pressure. An air-tight pressure actuator (26) is operatively connected to the outlet end and to one of the axial bearings (24) to exert a force on the axial bearing (24) proportionally to a pressure of the outlet end.
