Domestic turbofan engine: Launched in China-made jet turbofan engine In the past few decades,international trade database turbofan engine has become the mainstay of modern aviation, and it has been widely used in various types of aircraft. However, due to technological limitations and the needs of national strategies, China's aviation industry has not been able to launch its own domestic turbofan engine, but has to rely on imports.Until recently, after more than ten years of research and technical efforts, China's most advanced turbofan engine, the WS-20, has been successfully put into use, which also means that China's aviation industry has entered a new era. The WS-20 engine is developed and produced by China Aviation Industry Corporation (AVIC). It is the first high-channel ratio double-rotor turbofan engine in China with completely independent intellectual property rights. The engine has the advantages of advanced technology, simple maintenance and reliable performance. It also has the remarkable characteristics of low noise, low emissions, economy and energy saving. It is one of the aviation engines representing the highest level of aviation technology in China. The thrust of the WS-20 engine can reach the 12-ton level, which is suitable for a full range of large military and civilian aircraft, especially for C919 civil airliners and Y-20 large transportation.The development of aircraft and other national key projects has filled the gap in the field of China's aviation engines and achieved an important breakthrough in China's independent innovation. At the same time, the WS-20 engine uses a large number of new technologies and materials in the design, manufacturing and testing process, such as advanced coatings used to manufacture internal high-temperature components, new alloys to increase material strength and toughness, composite materials that reduce the quality of sound-absorbing structures and have better sound insulation effect, etc., which enhance The breakthrough performance and service life of the WS-20 engine have made China's aviation industry more competitive and internationally influential. In addition to the WS-20 engine, China's aviation industry is also actively developing other models of advanced turbofan engines, such as the WS-15 for medium-sized transport aircraft and medium-sized passenger aircraft, and the WS-13 for medium-altitude drones and missiles.The launch of these engines will help improve China's technical strength and market competitiveness in the field of aviation, and also lay a solid foundation for the future development of China's aviation industry. Although the WS-20 engine is one of the successes of China's aviation industry, its launch also means that China's aviation industry still faces many challenges and opportunities in technological innovation and international market competition. Therefore, China's aviation industry needs to further strengthen scientific and technological innovation, improve product quality and technical level, actively expand the international market, further improve its voice and core competitiveness in the field of aviation, and make greater contributions to the rapid development of China's aerospace industry. In a word, China's turbofan engine technology is making leaps and bounds, and the launch of the WS-20 engine has also opened up new space for the development of China's aviation industry.It is believed that in the near future, China's aviation industry will make more brilliant achievements in turbofan engines and other fields, creating more flight devices and aviation devices with independent intellectual property rights and innovative high-end standards for China.
