Technology: breaking the hegemony that monopolizes the world

"Also, in addition to the high-temperature alloys for parts, I have seen your project progress. The development progress of powder alloy components and spare parts for maintenance and modification is still relatively slow. You need to pay attention to this.

After all, all the equipment of aerospace projects need excellent materials to cooperate with maintenance and extend the service life.

American P\u0026W Corporation first pioneered the use of powder superalloy discs for aero-engines, and our research on powder superalloys in Daxia started relatively late, but caught up quickly, and even developed the highest strength powder superalloy FGH95. Its maximum operating temperature is 650°C, and according to our design environment, the maximum operating temperature of powdered superalloys should be close to 900°C. "

Listening to Gu Qing's "nagging", Sun Ke skillfully took out the curly panel that he carried with him, flicked it casually, and a tablet appeared in his hand.

While recording, he quickly recorded the text. When he encountered some important project reminders, he had to dig out the project plan and draw the emphasis mark. At the same time, he had to keep up with Gu Qing's thinking and give feedback at all times.

The salary of Kyushu R\u0026D personnel is high, but the pressure is really high.

Those ordinary Ph.D.s who enter the project team often need to drink Taoyao and struggle for a period of time to adapt to this high-intensity work.

Therefore, outside netizens complained about the scientific research and technology of Kyushu Science and Technology all day long, but the technicians in the Kyushu Science and Technology Research and Development Post did not respond much.

Looking at the data, adjusting the process, and sorting out the materials every day is very busy. Who has time to socialize?

When Sun Ke once again realized how much Gu Qing attached importance to the materials of each component, his eyes became much quieter and deeper.

The requirements made by Mr. Gu are not the material requirements for ordinary aerospace equipment, and even some extreme conditions are set higher than the requirements of some military projects he has participated in.

Most of the main maintenance items of aero-engines are to replace the hot end components made of superalloy and other materials.

When he was working in an aircraft manufacturing group, Sun Ke learned that the major forces of Blue Star now attach great importance to spacecraft, and even the overhaul and maintenance of space shuttles and fighter jets cost a lot of money.

For example, the performance recovery of major components: damage to components caused by high temperature, corrosion and fatigue will eventually cause the performance of the core machine to decline.

There is also engine performance recovery, dismantling the core engine, checking the condition of air path components such as blades and turbines, and performing necessary repairs and replacements.

As well as consumable parts such as drums, discs, bearings of compressors and turbine discs, which have a fixed life, they need to be replaced once they reach the end of their life, regardless of their condition.

With so many requirements, Sun Ke guessed that his company was probably engaged in fighter jets when he thought of the set of design drawings made by the design department that looked like recreational fighter jets, and the old test planes he had seen several times in the wind tunnel.

After all, don't look at how the major forces of Blue Star boast about the new generation of fighter jets and the next generation of future fighter jets. In fact, every performance innovation and upgrade of fighter jets comes from the innovation and upgrade of materials.

Without good enough high-temperature alloys, the core material of the first-generation turbojet engine would not be able to keep the turbojet engine running. For the turbofan engine, the core material of the engine can reach an astonishing 1200°C operating temperature. At the same time, the high-temperature alloy has been upgraded and innovated to the technology of single crystal superalloy to complete the landing of the fourth-generation turbofan engine.

Now Kyushu Science and Technology has a Titan Star department working on materials, and at the same time, Sun Ke and others are in charge of major material project research laboratories to cooperate with Titan Star's large projects to tackle key materials.

Because of the outstanding scientists and engineers at home and abroad, as well as the inclination of resources within the company, Kyushu Technology has developed and manufactured deformation, casting, equiaxed crystals, directionally solidified columnar crystals and single crystals in the field of superalloys in just a few years. Alloys and some materials have reached the international first-class level.

It is precisely because of the progress of these materials that the Aerospace Department of Kyushu Science and Technology can send Ergou to the sky with such confidence, and arrange manned spaceflight in full swing.

In fact, the aerospace department also thought about reducing a part of the resource investment in the early stage. If these alloy materials can be made in China, use domestically produced materials, and if they can reduce "extravagance and waste", they should be diligent and thrifty, because the project of material research and development is not directly proportional to the input and output. Often, a few million dollars can buy enough ready-made materials for a few million dollars.

It's just that among the high-temperature alloy purchase channels currently open to Kyushu Technology in Daxia, there are still many problems with these alloys that engineers don't want to see.

Many metallurgical defects, poor structure uniformity, high content of impurity elements, etc., directly lead to low strength and service life of the material, so that some aerospace equipment developed by the aerospace department in the early stage can directly change from the height of the chart scheme to the original design. Into the real fight Xixi.

While Gu Qing was instructing various projects, he was also looking at some information provided by Xuanwu and Sun Ke at the same time.

When we see that partners such as Daxia Shunfu Special Steel, Gangyan Nagao, and Western Superconductor have implemented production capacity expansion and research base projects, and these cooperative enterprises are also very cooperative in starting new process manufacturing while developing and updating process materials. At that time, he had a hope that he, a top laner, had endured the pressure for several years, and finally saw that other lanes developed and could play in a team.

Xuanwu even quoted some comments from the media: The concentrated expansion of superalloy enterprises fully shows that the industry is booming, but it also reflects from the side that the international environment is unstable. The shadow of war is gradually affecting enterprises. Wartime may be about to arrival.

When seeing this comment, Gu Qing neither underestimated nor ignored it. Because after reading that document, he knew clearly that wartime was indeed not far away.

When Gu, the founder of Kyushu Technology, finished his "suggestion", Sun Ke had already recorded an audio file that lasted forty minutes, and the page number of the file on the tablet also reached 29 pages, which shows that his "content is rich" ".

Even if there are professors from ordinary universities who can understand the content recorded on Sun Ke's tablet, I am afraid that all future papers will be settled!

After Sun Ke finished recording the content, he also reviewed what he had just recorded, and said with emotion in his heart: "If these projects are successful, I am afraid that the Nobel Prize in Chemistry will not need to worry about screening and review issues for more than ten years, and go directly to the company's project Just choose someone from the department.”

When Gu Qing saw that the person in charge stopped writing, he asked slowly: "Do you remember clearly?"
