Chapter 465

The air in the meeting room suddenly condensed. No one spoke. All he heard was Stanley swallowing and spitting and making a grunt.

The super-7 fighter added special turbine blades to greatly improve the thrust of the engine in a short time, and realized the excellent flight performance of super-7. This is impossible to fake. Everyone is watching.

Otherwise, Stanley could not have been fooled by Qin Guan's words alone, and this turbine blade must be a secret of the Han state and would never be taken out easily.

NiuGuo has lagged behind Yingguo in engine development. For example, the performance of Yingguo's F100 engine has thrown NiuGuo off the street. Their turbine front temperature has reached more than 1700. Looking at the engine used in Europe's newly developed gale fighter, the turbine front temperature is only 1327 degrees Celsius, which has gathered the technology of the whole of Europe.

Now, Qin Guan says that their turbine blades have reached the level of 1700 Kai, which is amazing. Of course, Luoluo company wants this technology.

"Do you really have such technology? We don't believe it," Stanley said to Qin Guan.

Now, in fact, it can be called doubt or deception. If you have it, take it out.

"Sorry, sorry, I'm late." just then, a voice came from outside. Professor Zhang finally came to 4430 factory after a long journey. He couldn't help but feel sorry when he came in, carrying a briefcase in his hand.

He walked almost all the way to Qin Guan's side, and then opened his handbag.

"This is the blade we made that matches the shape of Spey turbine." Professor Zhang took out a blade carefully wrapped in a special box in his briefcase.

The size of the engine is very large, but the length of the turbine blade is very short. Now it is more than twenty centimeters, almost the same as a ruler. Dozens of blades are finally welded to the blade disc by special welding method.

When Professor Zhang took it out, he took it seriously, while Qin Guan handed Stanley the whole box in a big way: "This is the latest research result of Professor Zhang. You can take it back and test it to see whether its performance meets the standard I said. Otherwise, I'm afraid you won't believe it. Next, we should continue to strive to convert the products in the laboratory into factory production and make this turbine according to the current blade specifications of Spey engine."

Qin Guan said to Professor Zhang, "Professor Zhang has worked hard. Sit here."

Professor Zhang sat next to Qin Guan. Now he has understood Qin Guan's pains.

Although Professor Zhang doesn't want to take credit, the patent of this kind of leaf can only be declared by himself. As his own credit, now it is mainly to fool the Niu people opposite.

With the naked eye, it is impossible to see the internal crystal structure. It can only be observed through an electron microscope. But now, when you open it and look at the shiny turbine blade inside, Stanley knows that the performance of the blade is absolutely good. Look at the color and surface finish. Then, the assistant took a magnifying glass and carefully looked at the metal lines on the blade Li, it really looks like a single crystal blade.

"This is only our initial product." Qin Guan continued, "thanks to our professor Zhang, who has been studying carefully in the material field for many years, its performance can be further improved. At least another 50 Kai is absolutely no problem, right? Professor Zhang?"

Professor Zhang picked up the cup and was about to drink water to moisten his throat. When he heard that Qin Guan was bragging again, he had to open it 50 times more. He almost sprayed out the water.

General manager Qin Guan, are you an expert or a layman? One metal has its limit. There are so many limits of this metal. If you want to improve, it's not so easy unless you use new metal!

Sure enough, this sentence attracted Stanley on the opposite side: "continue to increase by 50 Kai?"

"Yes." Qin Guan said carelessly, "we are still developing new alloys. Needless to say, 50 Kai is our goal. Our ultimate goal is to increase 200 Kai and the turbine front temperature to 190 Kai."

Although this is bragging, now, if the blade in front of us can withstand 1700 Kai, it is quite strong.

Now, the Han people have given this manufactured blade to their own side. What's next?

"If this blade can meet your performance and give us the full set of technology, we can cooperate in improving the Spey engine," Stanley said "If we increase the turbine front temperature and improve the compressor, we will probably increase the thrust of the engine to 11.5 tons. However, it also requires a lot of money. Let's be clear first. We only provide brains, we don't provide funds!"

Just now, Stanley changed his mind. We only provide brains, not funds!

"Of course." Qin Guan said, "the modification of Spey will become a key project of our northern industry. You can rest assured that we have enough funds. At the same time, I suggest that we should take a bigger step. For example, we also have technical reserves for compressor materials, which can further improve the performance."

In the engine, the thrust is only an indicator, and the other indicator is its own gravity. The ratio of the two is the thrust to weight ratio. The larger this value is, the better the performance of the engine.

On the one hand, it is to improve the thrust of the engine, on the other hand, it is to reduce the gravity of the engine. All these require the development of new materials. In addition to turbine blades and compressor blades, the use of new technologies can reduce the self weight.

"Well, after we have measured the performance of this turbine blade, we can discuss the details," Stanley said. "The development of the engine is very expensive. You should be prepared."

Perhaps a small problem will haunt the team for a long time and burn a lot of money. No one dares to make sure.

"Yes, of course," said Qin Guan.

Qin Guan is not afraid of burning money. There are money cemeteries. How much do you want.

"We'll start discussing the specific project in three months," Stanley said. "Let's take this turbine blade with us first."

The purpose of coming to China this time is to the turbine blade. Now, the purpose has finally been achieved. If the Han people cheat after going back, don't count on the further localization of their Spey!
