What Is the Jet Engine Oil System?

For a jet engine to properly function with high performance and reliability, it requires a continuous flow of oil. Oil plays various roles for an engine assembly, serving to cool hot parts, lubricate moving assemblies, and remove the buildup of debris. For the oil system to function with ease, all parts need to function together so that oil can be stored, cooled, directed, and distributed as necessary. With the grand importance of the jet engine oil system, it can be very beneficial to have a general understanding of its design and functionality for proper care and use.

In order for oil to reach various aircraft engine components, it must be transported through various pipes and internal flow passages. When the engine is completely shut off, there is a possibility of a siphoning effect occurring, that of which causes tank draining when the tank is situated above the supply nozzle. To prevent such issues from happening, an anti-siphon system should be installed. Another issue faced by oil systems is unusual output pressure values that come about during cold starts, that of which poses a risk to the supply pump. To prevent damage, a pressure relief valve will be installed.

For a pilot to guarantee the proper functionality and health of the jet engine oil system during flight, a monitoring system is typically used. This system ensures that a pilot can remain aware of oil supply pressure, temperature, and quantity, as well as the amount of debris released by oil sumps. With more advanced systems, pilots may also be able to record and analyze monitored data for maintenance endeavors.

As stated beforehand, one of the main roles of the oil system is to supply oil to various aircraft hardware parts for a means of achieving lubrication. Lubricating oils are especially important for all bearings and gears of the engine assembly, those of which use oil to minimize the amount of friction and wear faced during standard operations. When transporting oil for lubrication, it is important that the pressure within the sumps is always lower than the exterior pressure, ensuring that leaks do not occur. If a leak were to happen, pollution may spread to air bleed components, potentially leading to an engine fire. Because of this hazard, it is paramount that regular inspections are carried out for all aircraft engine components, oil system parts, carbon seals, and other related items.

Lubricating oil is supplied through two or more oil sumps, and each is pressurized and sealed for proper functionality. To prevent poor oil quality and excessive heat, a proper amount of oil should always be supplied. Additionally, different types of oils may vary in their level of maintenance, speed ranges, and other properties, making it important that operators properly choose products that accommodate their needs.
