Chapter 370 Difficulty
Engineer Xu had already made up his mind that if Wu Tong made outstanding contributions in this area, he would immediately report it to him. What's wrong with becoming Wu Tong's assistant and helping her?
Completing their aircraft carrier dream is the most important core element. Everything else can be ignored for this group of purely patriotic scientific researchers!
Wu Tong flipped through the gas turbine information in her hand. The design concept of the gas turbine was so different from that of aircraft engines that she couldn't help but feel ashamed of her previous thoughts.
Wu Tong accepted Li Huaimin's request and did a lot of research and study in preparation for the academic conference while preparing for the conference. She studied almost all the information about ships that she could collect, laying a solid foundation.
When she really started studying this field, Wu Tong felt that she had been a little too confident when she first agreed to it.
The ship sector is completely different from the aerospace sector that Wu Tong has been working on for the past two years. The large diesel engine used by the Ningliao aircraft carrier, which is her focus, is fundamentally different from the aircraft engine!
She is now very familiar with aviation. When she sees the wing, her mind will jump out and generate a series of design and development concepts for wing surface vortices; when she sees the belly, she will directly start to consider the lifting body layout and aerodynamic layout, and how to make it more perfect. When she sees the all-moving horizontal tail, Wu Tong can almost spontaneously deduce the control and fly-by-wire system...
Wu Tong can immediately give results and deductions for some simple data and designs without thinking, and this is almost becoming a habitual instinct. In her mind, she has fully mastered the logical chain of knowledge related to aerospace. This is Wu Tong's biggest gain in the past two years.
However, when it comes to the ship section, she is still only at the superficial theoretical level. It's just that, having remembered those theories, there is still some distance to go before she can truly connect them to practical application!
When her research on aircraft carriers can be as easy to use as on aircraft engines, it can be considered a true success!
Gas turbine is a very large technical field, and its complexity is no less than that of the aviation WS engine at that time!
No matter how things change, the gas turbine remains essentially the same. It is an internal combustion power machine that uses a continuously flowing gas as the working fluid to drive the impeller to rotate at high speed, converting the energy of the fuel into useful work. It is a rotating impeller heat engine.
In the main process of air and gas in a gas turbine, the gas turbine cycle consists of only three major components: the compressor, the combustion chamber and the gas turbine. It is generally called a simple cycle, and most gas turbines adopt a simple cycle scheme.
As soon as Wu Tong read the information about gas turbines, the theoretical knowledge about this part began to come alive in her mind. She was even able to do two things at once, scanning the information with her hands and eyes, and consulting with Xugong on the development and current status of domestic gas turbines.
"In the past, during those years, we had a hard time!
In the 1980s, relations between China and its overseas partners improved and recovered, entering a brief ten-year honeymoon period, and China began to cooperate with China in the fields of military, economy, science and technology, and trade.
Especially in the field of military cooperation, the United States lifted its nearly 30-year arms embargo on China and opened the door to arms exports to China.
At that time, China was extremely eager for advanced weapons and equipment, and was very eager to obtain advanced weapons and equipment from Western countries in order to change the backward situation of China's defense industry. It was at that time that we imported LM2500 gas turbines from abroad, which were intended to be used on the 112th "Ice City" ship and the 113th "Green Island" ship equipped with the Type 052 missile destroyer, and at the same time imitated them. "
Xu Gong knew all the development history very well. He introduced them to Wu Tong one by one and then he sighed deeply.
"However, the attempt to copy it ultimately failed. Although we are good at reverse engineering, we did not have the intermediate test data, no solid principles to rely on, and no way to solve the material problem. It was so difficult to copy the highly precise LM2500 out of thin air with only enthusiasm. It was normal for us to be laughed at and said we were dreaming!"
"No matter what, Mr. Xu, you predecessors had the courage to try at that time. We, the younger generations, should worship and admire you!" Wu Tong gave a thumbs up.
Without the stubborn trial and error of these predecessors, how could the two bombs and one satellite, as well as more scientific research results, be gradually established and born in China? Without these powerful deterrents, how could we have the peace and prosperity we have today!
The peace they enjoy today is all maintained by these ancestors who fought bloody battles and carried heavy burdens forward!
"Hehe... I don't need a young kid like you to comfort me. Failure is the mother of success. Failure in scientific research is commonplace. We are used to it!" Engineer Xu laughed, but was still moved by Wu Tong's recognition. The young kids today don't look down on their efforts back then. Instead, they admire them!
How wonderful, Lao Li, Lao Qian, did you see it? I saw it for you! Our great China has produced an amazing child. Now, she has taken over your stick and participated in the research and development of gas turbines. She is called a miracle. Maybe she will launch a big satellite for you. When the time comes, Lao Xu will toast you!
Wiping his face, Xu Gong pretended to be calm and continued: "In those years, importing was the mainstream. Later, we had a new goal. Ukraine inherited the Soviet Union's assets. We facilitated and successfully introduced the UGT-25000 gas turbine from Ukraine. It was the most advanced gas turbine developed by the Soviet Union. At that time, we were eager to change the situation that there were no gas turbines in our country!
In 1993, we successfully signed the "UGT-25000 Gas Turbine Production License and Single Unit Sales Contract" with Ukraine, and they provided 10 UGT-25000 gas turbines and transferred related technologies for domestic production! "
"After the successful introduction, it took another ten years. In 2004, we finally digested a lot of technology and completed the imitation. Although it was just a starting point, the power of the imitation was only a pitiful 28 megawatts! However, we had the foundation of the gas turbine!
It was not until last year, in 2011, that our state-owned gas turbines were truly fully localized and were first used on the second batch of Type 052C destroyers. After full localization, they were named QC-280 gas turbines and are expected to be fully used on Type 052D guided missile destroyers! "
