TURBINE ENGINES
A turbine engine has a section dedicated to each function, the cis performed continuously
The parts of a turbine engine are:
An air inlet
Compressor Section
Combustion Section
Turbine Section
Exhaust Section
Accesory Section
Systems for starting, Lubrication, Fuel Supply, and auxiliary purpo

Components of turbine engines are basically the samenomenclature of the various component parts becamanufacturer's terminology.
There are 4 types of turbine engines:
Turbofan.
Turboprop.
Turboshaft.
Turbojet.

ACCESSORY
SECTION
This space is for mounting ofaccessories necessary for operationand
control of the engine.
The basic elements of the accessorysection are:

COMPRESSOR SECTION
Its function is to provide sufficient air
amount to meet the requirements of thecombustion burners.
another function of compressor is suppliedbleed air for various purposes in the engine andthe aircraft.
Compressor Types
The two principal types of comprecurrently being used in gas turbinengines are centrifugal flow and a

DIFFUSER
The diffuser is the divergent section of the engine after the cand before the combustion section. It has the all-important freducing high-velocity compressor discharge air to increasedat a slower velocity.

COMBUSTION SECTION
The primary function of the combustion
section is, of course, to burn the fuel/airmixture, thereby adding heat energy tothe air. All combustion
chambers contain the same basicelements:
1. Casing
2. Perforated inner liner
3. Fuel injection system 4. Some means for initial ignition
5. Fuel drainage system to drain offunburned fuel after
engine shutdown
