FUEL Systems
Jet fuel is prone to solid particulate contamination, water, and biological contamination. There are many sources of contamination and they can be introduced at different stages of the engine life-cycle:
Manufacture of new aircraft fuel tanks/fuel systems
- Built-in and break-in wear debris
Service operation
- Environmental contamination during fuel storage or transport, including biological contamination
- Environmental contamination ingressed into the aircraft fuel tanks
- Component wear debris generated during operation
- Thermo-oxidative fuel breakdown products (e.g. varnish or carbonaceous deposits)
Maintenance
- Built-in and break-in wear debris
- Environmental contamination
Fuel system contamination and build-up of deposits in the fuel controls can negatively impact system performance. Problems include:
- Accelerated wear of fuel pumps, controls, etc.
- Corrosion
- Erosion of fuel nozzles and valves
- Jamming or incorrect response of fuel controls
- Fuel degradation
LUBRICATION systems
On any engine, the lubricant fluid is a natural repository for particulate contamination. This contamination comes from several sources and at different phases of engine operation:
Manufacture of new engines
- Built-in and break-in wear debris
Service operation
- Environmental contamination ingressed into the engine lubrication system
- Thermo-oxidative lubricant breakdown products (e.g. coke and carbonaceous deposits)
- Component wear debris generated during operation
Maintenance
- Built-in and break-in wear debris
- Environmental contamination
If this contamination is allowed to accumulate it can cause numerous problems including:
- Accelerated component wear of bearings, pumps, etc. wear
- Corrosion (water collection during engine storage)
- Coke formation and deposition on component surfaces (e.g., inner shaft coking)
With the largest and broadest portfolio of OEM-approved solutions that protect engines, auxiliary power units (APUs),
and integrated generators, we can help operators reduce their maintenance costs
and avoid unscheduled engine or component removals.
