The theory of the lubricants is an engineering and applied discipline related to the field of chemistry.

The minimum necessary training of aviation specialists in the field of the theory of the use of lubricants helps to improve the quality of service for aviation equipment and ensure flight safety.

The main purpose of the lubrication of any mechanism is to reduce the wear of rubbing parts and reduce the power that is spent on it. In addition, lubricants remove heat from heated engine components, protect machine parts from corrosion, clean the space between rubbing surfaces from wear products, mechanical impurities, etc.

Elements of hydraulic systems, according to the functions they perform, are divided into several large groups:

Pressure sources, these are the elements of hydraulic systems that are designed for the creation of hydraulic pressure and its maintenance during the whole flight. These are different types of hydraulic pumps and hydro-accumulators.
