DYNAMIC STABILITY AND MID AXIAL PRELOAD CONTROL FOR A TIE SHAFT COUPLED AXIAL HIGH PRESSURE ROTOR

摘要

A middle support member is used to provide axial support and control to the tie shaft. The middle support member includes a high pressure compressor coupling nut that applies a preload that allows the high pressure compressor stack to be installed separately from the high pressure turbine rotor through a kickstand.
