  • Gas turbine engine compressor and turbine section assembly utilizing tie shaft
    Patent number: 8517687
    Abstract: A gas turbine engine has a compressor section carrying a plurality of compressor rotors and a turbine section carrying a plurality of turbine rotors. The compressor rotors and the turbine rotors are constrained to rotate with the tie shaft. An upstream hub provides an upstream abutment face for the compressor rotors. A downstream hub bounds the downstream end of the compressor rotor to bias the compressor rotors against the upstream hub using an abutment member. The downstream hub has a rearwardly extending arm which provides a stop for the turbine rotors. A second abutment member is tightened on the tie shaft to force the turbine rotors against the downstream hub to hold together the turbine rotors.
