Core Major Module
Purpose:
Provide the energy to drive the LPT
Components:
The core major module consists of eight maintenance modules as follows: HPC rotor, HPC front stator, HPC
rear stator, combustion case, combustion chamber, HPT nozzle, HPT rotor, HPT shroud and first stage LPT
nozzle.
Description:
HPC rotor is a nine stage, high speed, unitized spool-disk structure. The rotor consists of five major parts: the
front shaft, the 1st and 2nd stage spool, the third stage disk, the 4th through 9th stage spool and the compressor
rear (CDP) seal.
HPC front stator, consists of: front casing halves, extension casing halves (configuration 1), IGV’s and first 5
stages of stator vanes. The IGV’s and the 1st through 3rd stage vanes are variable, the 4th and 5th stage vanes
are fixed. The
HPC rear stator consists of: rear casing halves, liners (Configuration 1), three stages of fixed vanes, and vane
shrouds. The rear stator is located inside the front stator extension and is cantilever-mounted to the rear stator
support. The rear stator support outer flange is mounted between the compressor front stator extension and the
combustion case.
Combustion case is a fabricated structural weldment located between the HPC and the LPT. It provides
structural interface, transmits engine axial loads, and provides gas flow path between the compressor and the
LPT.
Combustion chamber contained in the combustion case, consists of outer and inner cowls, 20 primary and 20
secondary swirl nozzles, dome, and outer and inner liners.................................................. |
