In the development of modern industry, a heavy equipment can play a very key role, it is heavy gas turbine , this technology has long been monopolized by foreign countries, China Not only did it start late, but it also experienced a period of technological gaps, which led to the gap of gas turbine technology being further opened by foreign countries, but now there is exciting news! That is, domestically produced gas turbines have broken the monopoly of the West for 70 years and achieved 100% localization? As the domestic heavy-duty gas turbine technology is put into use, people can't help but ask, how important is this equipment?

I believe that many people are unfamiliar with gas turbines, because in daily life, gasoline engines and diesel engines, or electric motors , are actually a type of gas turbine. Power, but mainly used in the field of large-scale industrial equipment, ship power equipment, and a small number of main battle tanks will be equipped with gas turbines as power. Compared with jet aeroengines, although the principles of the two are relatively similar, the era of the birth of gas turbines is even Before the turbojet and turbofan engines, China's gas turbine started after the founding of the People's Republic of China. At that time, we relied on the technology provided by the Soviet Union to master the domestic gas turbine technology.

. However, due to the influence of the relationship between the two countries, the development of gas turbine technology was stagnant. At that time, Western countries also began to fiddle, making the people think that gas turbine is just a backward technology and there is no need for large-scale development. Many domestic colleges and universities specializing in gas turbines also stopped enrolling students for a while, leading to gaps in our talent pool. However, with the development of the economy, the Chinese people once again realize the importance of gas turbines. China must master its own advanced Gas turbine technology.
The earliest domestic demand for gas turbines was in the field of ship power. At that time, due to the lack of advanced gas turbines, we could only buy them from abroad at high prices.For example, the UGT-25000 type provided by Ukraine, and China also planned to introduce advanced heavy-duty gas turbines developed by General Dynamics of the United States. However, even for the civilian market, Western countries still impose technical blockades on us. The only way to break the situation is to develop independent knowledge of China. Proprietary domestic gas turbine.

At present, in addition to the domestic destroyers, the West-East Gas Transmission Project and the West-East Power Transmission Project have already used self-developed heavy-duty gas turbines. In terms of breaking gas turbine technology, China has also chosen two-pronged approach. On the one hand, it vigorously promoted the development of domestic gas turbine technology. On the other hand, it also chose to go out and acquire western gas turbine companies. This has allowed domestic gas turbines to achieve such a major breakthrough in a short period of time. The main difficulties of this technology are actually mainly concentrated in In the field of blades, like aero engines, when a gas turbine is working, the temperature of its internal combustion chamber will reach thousands of degrees Celsius, and a high-pressure environment will be formed. If the blade material does not pass, it will directly affect the performance of the gas turbine.
At present, China has completely achieved technological breakthroughs in the technology of heavy-duty F-class gas turbines. However, in the H-class gas turbines with more outstanding performance, only a few countries in the world have mastered them. Therefore, in the next step, we need to continue to work towards H-class gas turbines. Among the technologies that China has made breakthroughs in the past, which ones did not come from nothing, and then gradually reached the world's advanced level, and now the gas turbine technology is the same, maybe with China's current scientific and technological strength, it can once again achieve the miracle of corner overtaking.
