The role of aircraft engine turbine blades

Aircraft engine turbine blades are key components that convert high-temperature combustion gas energy into mechanical energy. Located in the hot section of the engine, turbine blades operate in an extremely harsh environment, withstanding temperatures exceeding 1000°C and the immense centrifugal and aerodynamic forces generated by high-speed rotation.

The primary function of turbine blades is to receive the thrust of the hot exhaust gases from the combustion chamber and convert their kinetic energy into rotational energy for the rotor shaft, enabling continuous engine operation. To achieve efficient operation, blades are typically constructed of high-temperature resistant alloys and feature hollow cooling channels and thermal barrier coatings to enhance their heat resistance and service life in high-temperature environments.

The high performance of modern aircraft engines relies heavily on the advanced manufacturing technology and materials used in turbine blades. Therefore, turbine blades are not only technology-intensive products but also a crucial indicator of aircraft engine performance.
