Description
technical field
[0001] The invention relates to the technical field of aviation structural materials, in particular to a SiC f / SiC composite material flame cylinder and its automatic preparation method. Background technique
[0002] The combustion chamber is one of the core components of an aero-engine. Its main function is to convert the chemical energy of the fuel into heat energy through combustion, so as to improve the ability of the gas to expand in the turbine and nozzle. In the structural composition of the combustion chamber, the flame tube is The place where the combustion is organized is a key component to ensure air splitting, sufficient combustion, uniform mixing and effective cooling of the wall. The reliability, economy and life of the combustion chamber depend to a large extent on the reliability and reliability of the flame tube. Therefore, the development of a high-performance and long-life combustor flame cylinder plays a vital role in improving engine pe...
