CFMI PROPRIETARY INFORMATION
The High Pressure Compressor (HPC) is mounted between the fan frame module and the combustion case.
The HPC, which has 9 stages, increases the pressure of the air as it passes from stage to stage, to supply the combustor section.
It consists of the following modules :
- The compressor rotor
- The compressor stator
The compressor stator is made up of two parts. The front is supported by the fan frame and the rear is attached to the combustion case.
The HPC has pipe connections that duct bleed air for both engine and aircraft use.

Borescope ports
The lower stator case has a series of plugged ports to allow for borescope inspection of the rotor and stator vanes.
There are 9 borescope inspection ports located at approximately the 5 o’clock position and they are numbered S1 thru S9, where S1 is the most forward.
S7, S8 and S9 plugs are double plugs connected by a shaft. A spring-loaded system enables the outer plug to drive the inner plug.
Both inner and outer plugs have specific torque values.
