Aviation manufacturing is the most concentrated field of high-tech in the manufacturing industry. The entire manufacturing process has extremely high requirements for materials, processes, processing methods, test and test, and aero-engine technology is the cutting-edge representative of high-tech. Aeroengine technical features: complex working conditions, high manufacturing requirements, long development cycle, and high development costs. After more than half a century of development, the global aviation turbine engine technology has made great progress. The foreign aviation engine manufacturing has reached a fairly high level of technology. Its development trend is mainly reflected in three types of fighter aircraft, transport aircraft and helicopters. On the engine. Countries in the forefront of aero-engine technology continue to implement various technological development plans to promote the improvement of engine performance. In the process of implementing these technological development plans, new technologies are emerging, and efficiency and economy are the future development direction of the engine.
Military aviation engines still have a generation difference at home and abroad: China's aviation engine development level still has a large gap compared with the world's leading countries. At present, China's third-generation fighters are beginning to be equipped with troops, and the Taihang engine will realize the localization of the third-generation fighters. The fourth-generation fighters are already under development, as well as carrier-based aircraft, etc., and the matching engines are also under development. The successful development of Taihang engine is an important leap in the history of China's aviation engine development, making China into the ranks of the third-generation aero engine development country, and achieving a leap from medium thrust to large thrust in the independent development of aero-engine.
The status quo of civil aviation engines: the monopoly of foreign companies and the start of domestic enterprises. The global civil aviation engine market is almost entirely occupied by several giants such as GE, PW, RR and SNECMA or their joint ventures. China is almost blank in the field of civil aviation engines. It is expected that the engines of the first batch of domestic commercial aircraft will obtain airworthiness certificates in 2016, which is mainly matched with the time of domestic large aircraft.
Industrial gas turbines are widely used: industrial gas turbines are similar to aerospace gas turbine engines, but their output power is more widely used. It is understood that the Western Navy has more than 1,300 ships of various types and employs more than 3,000 gas turbines for power. China's ships use diesel engines, steam turbines, etc., and most of the gas turbines used are mostly imported. However, the localization rate of marine gas turbines will be further improved, and domestically produced gas turbine models will appear more and more on China's naval vessels. China's heavy-duty gas turbine manufacturing mainly takes Nanjing Steam Turbine Works, Harbin Steam Turbine Works, Dongfang Steam Turbine Works, Shanghai Steam Turbine Works, Hangzhou Steam Turbine Works as the main units, and the development of light gas turbines is concentrated in aero engine manufacturing units.
