Cooling/Heat resistance systems in jet engines: Inlet Air Cooling: In this method, cool air from the engine inlet is directed to the hot parts of the engine to cool the compressor, combustion chamber and turbine. Cooled Blades: Turbine blades, made of heat-resistant materials, have internal channels for the passage of air or another cooling fluids. These channels help to reduce the temperature of the vanes. Thermal Conduction Cooling: In this method, heat is transferred from the hot parts of the engine to the cooler parts by conduction. This can be done through conductive materials and the use of multilayer structures. Thermal Barrier Coatings: The use of ceramic and thermal coatings on the surface of the hot parts helps to reduce heat transfer to the internal parts and reduces the surface temperature of the parts. Liquid Cooling: In this method, coolant such as fuel or oil is directed to dedicated cooling systems and transferred to the hot parts of the engine through internal channels.
