Industry-specific tariff code reference

Large engine (heavy! The Industry-specific tariff code referencelarge engine is shockingly launched!) Large engines play a crucial role in the development of today's world. They provide power support for aviation, navy, industry and other fields. Of course, the complexity of such a "big" machine itself is also limited. However, today, with the continuous improvement of technology, large engines have also undergone great changes. Therefore, today we will talk about the recent new progress of large engines in technology, application and other aspects. One. LaserCutting technology With the continuous development of laser cutting technology, laser cutting technology is also more used in the manufacture of parts inside the engine. Laser cutting has the characteristics of high accuracy, fast speed and not easy to damage. This innovative process can greatly shorten the production time, and the quality and stability of the machine parts with higher requirements are also greatly improved. At present, the regulation of laser cutting technology is relaxed, and the cost of use is further reduced, attracting more and more institutions and companies to participate. II. Aerodynamic design In the design of large aircraft engines, aerodynamics is a very important factor. The calculation and simulation technology of modern aerodynamics has made great progress, which can simulate airflow, combustion and noise under various working conditions. Thus, the design of the engine can better meet the needs of customers, improve the service life, and ensure related factors such as flight efficiency and safety.Three. Digital control With the development and maturity of artificial intelligence, the design of the large engine control system has also been subverted. After a long period of learning and accumulation, the application of digital control technology is gradually being integrated into engine control. Compared with the original control method, digital control technology can carry out more accurate control according to the set conditions, and even optimize the problems brought about by the design, bringing more usage scenarios to large engines. Four. The improvement of gas turbines is an irreplaceable and important part of large engines. Strictly speaking, it is a thermal system and an engine component that generates power by the flow of high-temperature and high-pressure gas. In order to keep the performance of large engines in an excellent state for a longer time, the mechanism is constantly being optimized, such as guide blades and turbine blades.Material and process improvement, etc., new gas turbine driving systems are also gradually emerging, and have been promoted and applied in the industrial sector. Five. Optimization of thermal protection materials With the improvement of the comprehensive performance of large engines, the research and development of new materials is crucial to the optimization of engine performance. As a key manufacturing material, thermal protection materials have been widely developed and applied. These materials can effectively resist oxidation, wear and other problems under high temperature and high pressure conditions, greatly improving the sustainability and service life of large engines. In general, with the development of science and technology, the application fields of large engines are becoming more and more extensive. Although it is limited in use, it is constantly optimized and improved in details. Large engines have become an important technology and market presence. We believe that in the near future, large engines will usher in new breakthroughs and progress.
