Utilizing high-temperature and high-strength materials, along with advanced cooling technology, the system operates in a high-temperature and high-pressure environment. In this environment, the gas expands and performs work within the turbine, propelling it to rotate at high speed and thereby driving the compressor. Turbine wheel - turbine blade is an airfoil component that converts the energy of gas flow in the turbine passage of an aeroengine, and is one of the core components of an aeroengine. High-temperature, high-pressure gas flows through the stator blade passage and expands, resulting in a decrease in pressure and an increase in velocity; as the gas flows through the rotor blade passage, a pressure difference is generated on the pressure side and suction side of the rotor blades, which drives the turbine rotor to rotate at high speed and produce mechanical work.
