How does the gas turbine's lubrication system primarily work?

The lubrication system of a gas turbine primarily works through a continuous flow of oil, which is critical for maintaining the proper function and longevity of the engine. In a gas turbine, various components such as bearings, gears, and shafts generate considerable friction and heat during operation. To mitigate wear and potential damage, oil is continuously circulated through these components.

This oil provides a protective film between moving parts, minimizing direct contact and reducing friction. Additionally, the oil helps to dissipate heat generated during operation and carries away contaminants that could lead to component failure. The design of the lubrication system usually includes an oil reservoir, pumps, filters, and cooling components to ensure that the oil remains at the correct temperature and is free from impurities.

In contrast, other methods mentioned are not used for gas turbine lubrication. Compressed air is often used for a variety of auxiliary systems, but not for lubrication. A gravitational system may be found in some mechanical systems but does not apply to the controlled lubrication needed in gas turbines. Water circulation is typical in cooling systems but is not suitable for lubrication due to water's corrosive properties and inability to create an effective lubricant film under the operational stresses of a gas turbine. Thus, the continuous flow of oil is the essential method for effective lubrication in
