Lubrication System

 

A lubrication system is an essential component of a micro gas turbine engine, as it helps to reduce friction and wear on the engine's moving parts. The lubrication system is responsible for distributing lubricant, typically oil, throughout the engine to the various bearings, gears and other components that require lubrication.

Here is an outline of a typical lubrication system in a micro gas turbine engine:

1. Oil Pump: The lubrication system starts with an oil pump, which is responsible for drawing oil from the oil reservoir and pressurizing it. The oil pump is typically driven by the turbine's gearbox or an electric motor.
2. Oil Filter: The oil is then passed through an oil filter, which removes any contaminants or debris that may have entered the lubrication system.
3. Oil Cooler: The oil is then cooled by passing it through an oil cooler, which helps to dissipate heat generated by the engine's moving parts.
4. Oil Gallery: The cooled and filtered oil is then distributed throughout the engine via an oil gallery, which is a network of channels and passages that carry the oil to the various components that require lubrication.
5. Oil Jets: Oil jets, which are small nozzles that spray oil onto the components that require lubrication, are located at various points throughout the engine.
6. Control Unit: A control unit, which is responsible for monitoring the lubrication system and ensuring that the appropriate amount of oil is being distributed throughout the engine, is also typically included.
7. Drainage: Finally, a drainage system is typically included to remove any excess oil from the engine.

It is important to note that lubrication systems can vary from one engine to another, and this outline is a general representation of a lubrication system, the specific details and design would depend on the engine's architecture and the manufacturer's design.
