About this file
This document is a parts list for a gas turbine engine system, organized by National Stock Number (NSN), Ordnance Part Number, and nomenclature. The list contains approximately 200+ components spanning multiple functional categories including compressor stages, turbine assemblies, housings, bearings, seals, valves, shafts, rotors, discs, nozzles, liners, and ancillary equipment such as fuel systems, oil systems, and control mechanisms.
The components are categorized by function and include high-pressure compressor (HPC) and low-pressure compressor (LPC) elements; high-pressure turbine (HPT) and low-pressure turbine (LPT) sections; bearing assemblies and associated housings across multiple positions; intake and compressor vane sets; combustor components including liners and covers; diffuser assemblies; sealing and bearing support hardware; fuel metering and pressurization systems; ignition systems; and accessory gear box (AGB) components. Several items reference "No USG Reference," indicating government-unique parts without commercial equivalents. The list also includes modification kits for field service and consumable items such as filter elements and humidity indicators. This parts catalog appears to support procurement, maintenance, and supply chain management for a specific military or government gas turbine engine platform, potentially for aircraft propulsion or power generation applications.
