TURBINE SECTION - DESCRIPTION AND OPERATION
___________________________________________
1. General
_______
The modules of the turbine are the high pressure turbine and the low
pressure turbine.
A. High pressure turbine module (Ref. Fig. 001) The HPT module consists of 1-stage nozzle and rotor. The nozzles are supported by the HPT case, the rotor is attached to the high pressure compressor rotor.
B. Low pressure turbine module (Ref. Fig. 002) The LPT module consists of 4-stage turbine, rotor, nozzles, stator case and rear frame. The rotor is connected to the fan. Surrounding the stator case is a clearance control manifold system.

HPT NOZZLE ASSEMBLY - DESCRIPTION AND OPERATION
_______________________________________________
1. General
_______ (Ref. Fig. 001, 002) The high pressure turbine (HPT) nozzle is a single-stage air cooled assembly that mounts in the combustion case and directs the gas flow from the combustion chamber onto the blades of the HPT rotor at the optimum angle. The major parts of the nozzle are 21 nozzle segments and inner support. The aft support and seal assembly, while not integral components of the HPT nozzle module are included since they attach to the HPT stator parts. 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320飛機維護手冊 AMM ENGINE 發動機 2(50)
