Chapter 1138: safe question

"Mr. Qin, you are frightened." A police officer said: "This is our negligence. We have been following these people for a few days. When we learned that they had come to Neuschwanstein Castle, we knew it was not good, but unfortunately there was still nothing. Stop them early."
No wonder the police came so quickly, in fact, they have been following these guys all the time.
At this moment, there is only one left to clean the battlefield inside. Thinking about the experience just now, everyone was sweating. Qin Guan secretly called for luck. He brought his wife, children and old people to go abroad for fun, absolutely not. Come to the abuser.
Look at Chen Rui again. This excellent test pilot is the most precious in the country. If he has any shortcomings, he will feel even more ashamed.
"What about Kelly? How is Kelly?" At this time, Chen Rui suddenly asked the woman again, and Qin Guan's expression became even worse when she heard Chen Rui's question.
Kelly? If it weren't for this woman, we would have been out of the way the first time, what is the dirty bullet, what is it for us?
Qin Guan was very dissatisfied: "It's still dangerous here, let's go."
Chen Rui looked back and saw that the police were constantly escorting the people out of the hall, but did not see Kaili.
"Let's go."
Qin Guan said.
The crowd followed Qin Guan and left in a vehicle provided by the police.
In the end, Qin Guan used his energy to harvest, but unfortunately he didn’t make it in time. He planned to reap the harvest when the police came in. The result was a step slower and let the last member of the so-called urban guerrilla team start. Fortunately, these people lost consciousness at the last minute and were killed by snipers, so no one would doubt themselves.
This experience was truly thrilling.
"Mr. Qin, the superior has come to instruct you to return to your country." Sure enough, Xiang Jing came to report just after he settled in a safe place.
Qin Guan's safety is of great importance, especially this time with his wife and children.
The first thing Qin Guan did when he went abroad was to complete the project with Hans State. This project was beautifully completed, defeating Mirage 2000, defeating F16, and finally let others have nothing to say, and can continue to advance this project.
And the second thing is to travel with your family. I have been traveling now. Although it is not very enjoyable, how can we continue traveling after such an accident?
Hearing Xiang Jing's words, Qin Guan couldn't help sighing. I still want to go to the chicken country, and I want to see the Arc de Triomphe. In the Arc de Triomphe, there must be a lot of mental power remaining, and I can absorb more spirits. Power to increase the upper limit of mental points. Now, these are all in vain. If Qin Guan wants to go, the domestic leaders will not agree. Qin Guan's safety is of great importance.
There are many protections of comrades on the secret front. Qin Guan's safety can be guaranteed, but who would have thought that various accidents would happen?
For example, this time, the so-called urban guerrillas hit their own side by surprise. No one expected that such a person would appear.
Therefore, Qin Guan can no longer stay abroad, he must leave Europa and return to his motherland.
Moreover, it is now in the country of Hans. Because of the agreement with the country of Hans, the Hans people value Qin Guan very much, but the country of chickens is different. Now people of the country of chickens can't wait to kill the troublemaker Qin Guan.
Therefore, if Qin Guan proposed to go to the chicken country at this time, I am afraid that he would not get consent.
"Well, let's go back to China," Qin Guan said.
After I go back, I can just try the latest production line cemetery, the production line of the F404 engine is exchanged.
Every time, Qin Guan couldn't enjoy himself. This time, with regret, he returned to the country. After living in the capital for a few days, he immediately went to the 4430 factory.
The research and development of the modified Spey engine has all ended. Therefore, the technical experts of Rolls-Royce from Niu Country have also returned. Now the 4430 factory is almost all the original scientific research personnel.
Of course, everyone knows that there is a huge gap between the engine field and foreign countries, so scientific researchers are working hard. During the New Year, almost all of them are spent in engine factories, and everyone is studying three generations of engines with great concentration.
A qualified engine is not only the design, but more importantly the material. If there is no qualified material, there will be no qualified engine.
Domestic material experts almost stayed in the 4430 factory, contributing their own strength to the development of new engines.
When Qin Guan arrived here, it happened to be in time for the ignition of the new core machine.
If you are developing an engine, the first thing you need to do is the core engine. With the core engine, a series of engines will appear.
For example, take this engine of its own, the Eagle State Air Force instructed GE to develop F101DFE on the basis of F101, so the F110 series was created. At the same time, GE and CFM, a joint venture of Safran, developed the CFM56 series of engines with the F101 core engine.
Therefore, later generations will have a new saying that the heart turbofan-10 of the third-generation domestic aircraft has a great relationship with the F110.
After Han Guo introduced the Boeing 737 in the 1980s, the CMF56 engine entered China's civil aviation. To some extent, the core aircraft of the F110 also came in.
It is said that the core engine of the WS10 engine comes from the core engine of CFM56-3, that is, the core engine of F101, and the F110 engine is developed from the F101 engine, so in a sense, the WS10 engine and the F110 engine are the same master. Cousin.
Rumors aside, the basic structure and parameters of Taihang engines are very similar to F110. They are all three-stage titanium alloy wide-string fans, nine-stage high-pressure compressors, single-stage high-pressure turbines and two-stage low-pressure turbine design schemes, namely 3-9-1 -2 structure.
Looking at the design indicators, some key parameters are also very similar, one is the channel ratio, the other is the fan diameter, and the third is the intake air flow.
For example, the bypass ratio of the F110 engine is 0.87, the bypass ratio of the WS10 engine is also above 0.8, the fan diameter of the F110 engine is 970mm, and the fan diameter of the Taihang engine is more than 950mm. The maximum air flow of F110 engine is 122KG/S, and the maximum air flow of WS10 engine is 120KG/S or more.
However, if you direct surveying and mapping and reverse engineering, you know it but you don’t know why. It takes a long way to figure out why this design is done.
Qin Guan doesn't want to go into details, after all, it's something for the future. Looking at it now, he has first-hand F110 design materials, and he can learn from it from the positive direction.
Qin Guan was also very excited when he heard that the core machine was ready to ignite, and went to the test bench together.
At this time, Qin Guan couldn't help but think of the turbofan-6 test run. What a pity, if they can seriously engage in scientific research, how about giving them F404?
Qin Guan really didn't dare now, for fear that they would ruin this project.
