Different Modules of Aircraft engine

There are mainly 17 different modular structures in an Aircraft engine. 1. Fan module. a) Spinner Code b) Fan blades c) Fan forward Case d) LPC stator e) LPC rotor f) Fan shaft g) Fan frame 2. Core module a) HPC Stator b) HPC rotor c) compressor rear frame d) combustor e) HPT stage 1 module assy 3. HPT module a) HPT stator b) HPT rotor 4. LPT module a) LPT assy b) Turbine rear frame 5. AGB- Accessory Gearbox

ATA numbering system

 An aircarft has a lot of parts, manufacturing them is one thing maintaining them is some other level challange. Thus to describe what needs to be done for what part requires a lot of documentation.  The easy way engineers have come up is to name each section of the aircraft as different title numbers.  ATA- Air Traffic association. It was created by people in ATA so called ATA chapters.  with 100 chapters ATA  So when some one says ATA chapter 72 it will always mean engine. ATA 27 flight controls ATA 32 landing gear ATA 72 is engine  and so on If we go even deeper. ATA 72-00-01 is fan module ATA 72-00-02 is core module ATA 72-00-03 is HPT Module ATA 72-00-04 is LPT module ATA 72-00-05 is AGB module and so on
