Chapter 467

Qin Guan slept very comfortably. Under his own promotion, Spey's imitation went smoothly, and has begun to improve. Domestic military aircraft will soon have a reliable heart.

Yes, it's reliable. This is what Qin Guan values most. After all, the research and development of turbofan engine is not so easy. Moreover, it involves all aspects. Even if you pull the F119 production line and send it to the factory, the factory can't process it immediately.

And look at the self-developed engine. How many years has it been used?

Qin Guan didn't have much psychological pressure. In contrast, the heads of the engine factory who came here were actually in a state of confusion.

"General manager Qin Guan is very tired and needs a rest." Xiang Jing said to several visitors, "your business will be discussed tomorrow."

With that, Xiang Jing wanted to go out. At this time, a middle-aged man left his seat with a box in his hand: "Comrade Xiang Jing, you are the Secretary of general manager Qin Guan. You still need your help for many things. It's a small gift. It's no respect."

Xiang Jing looked at each other with disdainful eyes and looked at the small box in each other's hand. Although she didn't open it, she also knew what was inside.

It must be a watch. I'm afraid the price is not low. Hum, do you want to bribe me? Xiang Jing wanted to refuse immediately, but later, an idea came to her mind. You might as well tease them.

"Well, OK, no problem." Xiang Jing took the small box: "if I have a chance, I'll say good words. Tomorrow, you should do well."

"Yes, yes, we must." the other party immediately said happily. Watching Xiang Jing put the box into her pocket, her hanging heart fell down.

Back in her room, Xiang Jing opened the box. Suddenly, it was glittering. This watch cost a lot! Even the watch he saw in NiuGuo is comparable.

These people are doing this. Look how I tease you! Xiang Jing thought in her heart.

The climate in the old revolutionary base area is still good. Now, it is the season of warm flowers in spring. Qin Guan slept comfortably and didn't wake up until half a day ago.

"It would be great if you could sleep in every day," said Qin Guan. As he said, Qin Guan looked at Xiang Jing. "In China, you don't have to protect me so closely?"

Qin Guan's meaning is very clear. Hey, men and women don't give and receive. I have a wife and children, and you are also pursued. In this way, if we stay in the same room, we will be gossip. Even if we are innocent, people's words are terrible, especially the general manager and the secret book. There are too many stories to tell.

Qin Guan was worried. Xiang Jing had blackened her face: "I just came to see if you wake up. Those guests have been in a hurry."

Qin Guanyi patted his forehead. No, I forgot!

"Tell them to come in," Qin Guan said.

After all, this is not the territory of Qin Guan. Without Qin Guan's office, Qin Guan is embarrassed to use other people's office. Anyway, the hostel has a large place, so we'll talk about it here.

"Come in," Xiang Jing shouted to the door.

It's at the door? Qin Guan was surprised. Are these people too anxious?

Outside, a dozen people swarmed in. Although the guest house's room was large, it was almost crowded.

"It's okay, everyone sit on the bed. Don't stand. Well, you tall boy, don't pestle there. Sit next to me." Qin Guan greeted me back and forth.

"President Qin is really polite. He doesn't have the airs of leadership at all." an old man said, "we have been entrusted by President Gu and want to report to you on the development of turbofan 6."

"The report can't be talked about. I'm glad you want to talk to me." Qin Guan said, "don't be shy. Let's speak freely."

Qin Guan was so kind that the visitor was not so nervous. He said to Qin Guan: "Our turbofan 6 project was initiated in 1964 to cooperate with the development of the new Jian. Later, it began to be officially developed in 1966. This is a high thrust turbofan engine with a maximum afterburner thrust of more than 12 tons. Its development has brought our engine development level to the ranks of the world's advanced level."

Qin Guan is no stranger to the situation of turbofan 6. The existing J-7 in the Han country can not adapt to the new air threat. Therefore, the Han air force put forward the technical requirements for designing a new aircraft more advanced than the J-7 fighter. After discussion between the air force and the aviation industry department, it was decided that the design of the new aircraft should be divided into two steps. The first step is to design a new aircraft and install two vortex ejectors with improved design The second step is to design a more advanced high-altitude high-speed fighter, code j-9, equipped with a newly designed afterburner turbofan engine, code ws-6.

The development index of turbofan VI is quite high, but is there such a foundation in the Han Dynasty?

No, before that, there was no self-developed engine in Han country. Even the backward turbojet was produced by introducing technology, which was too difficult.

How difficult is the advanced third-generation engine? Just look at the eagle country now. Their F100 engine can be awesome, but its reliability is not good. As a result, the F-15 is prone to engine problems.

Without any technical reserves and any pre research, if you want to get turbofan 6 out, it is a castle in the air.

Qin Guan is very patient now and listens to each other's explanation.

Even if the other party said the specific technical data, Qin Guan simply couldn't understand what transonic fans, afterburner with parallel inlet, etc. Qin Guan nodded while listening: "good, good."

Looking at Qin Guan's statement, the other party was even happier.

Finally, after more than an hour's report, Qin Guan said to the people: "this engine sounds very good. Our majority of scientific researchers have worked hard for more than ten years. For our country's advanced engine, we can make continuous progress with countless selfless researchers in our motherland."

Then Qin Guan yawned: "Oh, what's the matter? I'm sleepy again. It's noon. It's time for a lunch break. What else, everyone?"

Qin Guan's statement just made them very happy, but now, Qin Guan has this expression again?

"Well, Mr. Qin, let's introduce to you. You already know our turbofan VI. this engine, focusing on high altitude and high speed, is the most suitable power for our fighter. Look, can our newly developed aircraft use our engine?"

That's why they're here.
