Super Weapon Swap System

Like father, like son. Naturally, his son is also an outstanding engineer. How could this engineer be here? Even if the current conditions in xiongguo are not good, such families should not worry about their own lives?

Qin Guan glanced again and found that there were more than a dozen Xiong people here. Although Qin Guan had long fooled Xiong experts, it was still very strange to see these people here.

"Let me introduce it to you." it seems that knowing Qin Guan's doubts, old Kang said to Qin Guan: "This is Fedotov. He once took on the main task in the R & D team of r79 engine. Later, the project was terminated and hired by us. He has become an excellent R & D personnel of our turbofan-15 team. He has not returned home for a year."

The r-79 engine is the engine of the Jacques 141 vertical takeoff and landing fighter of Xiong Guo. This fighter project is actually marginalized in Xiong Guo. The people of Xiong Guo invested very little money and did not see much results. Later, the Han people joined in.

One of the most important schemes implemented by the Han Dynasty is the lift fan. In this way, the ablation of the deck by the lift engine is reduced, so that the project really has practical value.

The matching of lift fan and r79 engine has been carried out all the time. However, as we all know, the technology of r79 engine is not advanced. It is only a large thrust. In terms of thrust weight ratio, it is less than 6, even three generations of engines.

(many publications say that the technology of turbofan-15 comes from r79, and the thrust weight ratio rises from 6 to 10. Even if it comes from r79, it is a comprehensive upgrading and the crystallization of the hard work of Han's own technicians.)

Even such an engine is actually in the R & D stage and has not really completed the R & D. in the process of contacting with the technicians of Han country, Xiong Guoren began to admire the development of Han country and have a deeper understanding of Han country.

Therefore, it is normal that the turbofan-15 project led by Pan Lao needs a large number of technicians. These engine experts of Xiong Guo still have several brushes. After joining their own projects, they also put forward a large number of opinions, which makes the rapid progress of engine research and development in Han country. At the same time, Han country also gives them a stage to display, and both sides take their own So they signed a confidentiality agreement and joined the project.

Unexpectedly, some time ago, I asked the other party to buy 50 r79. Now, the project has ended! I know Xiong Guo is unreliable. Fortunately, the project has not been carried out and has not lost much.

"Is your father Sergei? He is a famous engine designer in the state of bear. We appreciate him very much. If you have the opportunity, please also invite your father to visit the state of Han." Qin Guan said.

Now, xiongguo is about to disappear. After the collapse of xiongguo, their engine technology has also stopped. The AL-41F engine comparable to the West has been completely abandoned. It is enough for them to show off that they have improved the third uncle with the obtained technology and turned into a 117s engine.

Research on engines requires a lot of capital investment. After the collapse of xiongguo, they no longer have the ability to do this. Their engine technicians will also lose a lot, and they can just continue to deceive.

"Yes, but he probably won't come. I've broken up with him for my sake," Fedotov said.

As a designer of Xiong Guo, he actually joined the R & D team of Han Guo. When his news came back, his father was of course very angry. When there was no hope of persuasion, he cut off the relationship with him. For Fedotov, it was nothing. Here, he developed the most advanced engine, which made him excited.

For an engineer, they are always the most eager for technology. Fedotov, a foreign monk, came to the state of Han and realized his life value. They have developed four generations of engines. What a great achievement! He was even more impressed by the advanced technology one by one.

"President Qin, you see, this turbine blade reflects your technological progress. Its processing technology is the most perfect, and Xiong Guo can't do it!" Fedotov said, picking up a magnifying glass and letting Qin Guan watch.

Qin Guan really can't see what's in it?

"Look at these small holes. After a long test run, they still work well without any signs of ablation. It's perfect! Look, do these small holes look like cat ears? It uses the advanced special-shaped hole laser processing system to process the special-shaped hole gas film cooling device of cat ears. With it, the temperature can be reduced by at least 150 degrees!"

Film cooling? As a military fan, Qin Guan can still understand it.

The turbine temperature of an aeroengine has a great impact on the performance of the engine. In the first generation of engines, the turbine temperature is only a few hundred degrees Celsius. Now, in the third generation of engines, the turbine temperature has reached more than 1500 degrees Celsius. If you want to have a thrust weight ratio of more than 10, the front temperature of the turbine must reach 17800 degrees Celsius.

At this temperature, ordinary materials have long been melted. This turbine blade is one of the key technologies of aeroengine. Whoever has powerful materials and high temperature will have advanced engine performance. All kinds of rare metals are used on it.

On the one hand is the material, on the other hand is the structure, such as spraying various high-temperature resistant coatings on it and using gas film cooling technology.

In fact, the film cooling technology is to make the blade hollow, fill the blade with air, and then spray it through the film cooling holes distributed on the blade surface, so as to form a coating on the blade surface and isolate the high-temperature and high-pressure gas ejected from the combustion chamber. If you have done University experiments, the principle of air cushion guide rail is like this.

However, the key to this technology is how to drill holes. Only by drilling high-density straight circular holes on the blade can the cooling performance be achieved. Drilling will inevitably reduce the structural strength and service life of single crystal blade. Therefore, the drilling process is very important.

Xiong Guo also has its own uniqueness in the technology of the engine of the third generation machine. However, Xiong Guo's processing technology is not strong. They use their advanced integration ability to realize the progress of the engine.

The technology of Han is beyond the reach of Xiong itself.

This technology is three-dimensional special-shaped hole!
