The turbine is the main part of the aircraft engine responsible for converting fuel into energy to drive the propeller blades. The article is devoted to the maintenance and repair of an aircraft turbine, including the basic procedures and techniques used to detect and correct defects and damage in the turbine. It also describes the process for diagnosing and analyzing turbine failures, and how to prevent such failures from occurring in the future. Turbine maintenance is critical to flight safety, and the article can be useful to both aviation professionals and the general public interested in aviation and technical issues. Reliability and resource, as practice shows, depend more on the number of load cycles and thermal cycles associated with starts, stops and changes in the engine operating mode than on the total number of hours of operation. The turbine is the most important unit of the engine, which determines its service life and reliability of operation. Cooled rotor blades make it possible to increase the working temperature of the gas in front of the turbine or to use less scarce materials for the manufacture of blades. Currently, two types of cooled rotor blades are mainly used: frame and composite blades.
