The technical difficulty of aircraft engines is extremely high. When aircraft engines are running, the internal temperature can reach thousands of degrees Celsius, and they are subjected to huge mechanical stress and airflow impact. Therefore, finding and developing high-temperature resistant and high-strength materials that can withstand these extreme conditions has become a huge challenge. Any slight error may cause component failure, which in turn affects the performance of the entire engine.
Designers need to design a structural layout that can both efficiently convert energy and maintain stability in a limited space. At the same time, it is also necessary to consider the performance of the engine under different working conditions, as well as factors such as maintainability and reliability, which makes structural design a highly comprehensive problem.
The advancement and complexity of manufacturing processes are also important manifestations of the technical difficulty of aircraft engines. Modern aircraft engines use many advanced manufacturing technologies, such as CNC machining, precision casting, surface coating, etc. The application of these technologies has greatly improved the performance and quality of the engine. However, the mastery and application of these technologies also require a lot of R&D investment and talent support, making the manufacturing process an important bottleneck in the development of aircraft engine technology.
Finally, quality control and reliability assessment are also important components of the technical difficulty of aircraft engines. Since the operating environment of aircraft engines is extremely harsh, the requirements for their quality and reliability are also extremely strict. During the manufacturing process, it is necessary to establish a sound quality management system and testing methods to conduct strict inspection and testing of each component and the entire machine. At the same time, reliability evaluation and verification are also required to ensure that the engine can maintain stable and reliable performance during long-term use. The implementation of these measures requires a lot of manpower, material and financial resources, which further increases the difficulty and cost of aircraft engine technology.
