DOC AIRBUS | AMM A320FHPC REAR STATOR ASSEMBLY - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
1. General
The compressor rear stator consists of the rear casing halves, 3 stages of fixed vanes, and interstage honeycomb seals. The halves are attached together at the 3 and 9 o'clock splitline with bolts. The rear stator assembly is found inside the front stator assembly and is cantilever mounted to the rear stator support. The outer flange of the rear stator support is installed between the front stator of the compressor and the combustion case. The rear flange has rabbets for close tolerance concentricity with the combustion case. The forward end is radially restrained by manifold supports attached to the front case to maintain concentricity.

Compressor Rear Stator Assembly2. Description
A. Casing
The rear casing halves are a matched set machined from an incoloy forging.
The casings have internally machined circumferential slots that retain stages 6, 7, and 8 stator vane segments. Stage 6, 7, 8, and 9 rub lands are hard-coated.
The casing contains ports for borescope inspection of internal area.

B. Vanes
The vanes in stages 6,7, and 8 are made into segments consisting of several vanes each. These segments are installed in circumferential slots in the casing. Each stage of vanes has shrouds with removable honeycomb seal segments attached to the inner platforms.
