In history, the Han state has successfully purchased the civil model of Black Hawk helicopter. Therefore, there will be no big problem with the purchase proposed by Qin Guan. Then, discuss with Sikorsky company about the moisture-proof and salt proof treatment of the civil model, and it will be a shipborne helicopter. As for the anti submarine weapons above, I can think of another way.

In the future, with the easing of relations with Eagle country, it is also possible to directly import anti submarine helicopters. Then, it is our own side that imitates this helicopter. It seems that we are too optimistic to introduce the production line of black eagle helicopter.

We have to base ourselves on self-study.

Just thinking of this, Qin Guan suddenly thought of something. Unconsciously, 1980 was approaching the end of the year. At the beginning, old Lu patted his chest and said that the mapping and imitation of male cats would be completed by the end of the year. I don't know how it was going?

I have nothing to do recently. Why don't you sneak in and have a look?

Moreover, last time at the air show, I fooled Grumman with a stealth model. Grumman finally decided to exchange their vacuum electron beam welding technology with their own stealth technology. Now, I don't know how it is going?

Without their own participation, I don't know whether Grumman has carried out cooperation.

With this idea, Qin Guan came to 6650 Institute.

It's winter now. There is heavy snow in the north. 6650 is located in the south. In contrast, winter is more difficult than the north.

Because in the north, heating has begun. The heating is very hot. The workshop is warm. If the sun shines in again, it will be more comfortable.

In the south, it is cold and chilly.

In such cold weather, the workshop under 6650 is still in full swing. Slogans can be seen at the gate of the plant.

"Fight for 100 days to repair the second batch of male cats."

"Work hard and successfully complete the repair task assigned by the superior."

"Contribute to the construction of the air force!"

Slogans, flying in the cold wind, bring people's blood, and when you go to the workshop, you can see the enthusiasm of the workers.

At the beginning, it was difficult for them to repair the fighter, because they did not understand and were not familiar with it. With the continuous repair work, it was easy to repair after they were familiar with the various structures of the male cat fighter.

Of course, we still order parts from Grumman company, take those parts, replace the broken parts, and then the maintenance can be completed.

The workers are working hard.

At the same time, the staff of the institute focused on the mapping imitation. A complete male cat was disassembled, all parts were mapped and drawn into drawings. This is a huge project.

Then, we need to replace it with our own self-developed parts.

For example, the engine needs to be replaced with its own Spey modified engine, and the radar needs to be replaced with the radar of institute 114. These need to be modified on the design drawing.

For researchers, it is also an absolute tight time and heavy task to complete the surveying and mapping task and then draw the map within this year.

Many people have moved their bedding here. When they are tired, they lie in their bedding and sleep for a while. When they are hungry, they chew the steamed bread. They work most of the time.

At the same time, a large number of drawings were input into the computer. In 6650 Institute, the latest batch of Hansen computers came a few months ago, and the designers also started computer-aided design.

Six months later, old Lu's hair turned white. His eyes were tired, but his face was full of excitement. When he saw Qin Guan, old Lu was even more happy.

"Mr. Qin, are you here?"

"Old Lu, you should also pay attention to your health." looking at old Lu's white hair, Qin Guan knew that he was burning his own life. Although he patted his chest at the meeting of the Ministry of aviation at that time, Qin Guan was very worried about being so desperate.

"It doesn't matter," said Lu. "For me, the J-11 is my life. President Qin, after our efforts day and night, we have completed all the mapping of the male cat fighter. Now, we have input all the data into our computer. Come here."

The computer room is very large. Obviously, it was transformed from a previous workshop. Here, relying on the heat emitted by the computer, the room is actually very warm. There are people surging in front of each computer. Generally, two or three people are constantly studying one computer.

"Thanks to Hanxin technology company for its strong support to us. We have the right to use these computers. Moreover, we still owe part of the required funds. We used these computers to speed up the design and finally completed all the surveying and mapping work."

Said, in front of a terminal, Lu Lao opened the interface.

Qin Guan opened his eyes and looked at the image above.

Computer design requires the powerful computing power of the computer. In the past, it could only be done with medium-sized computers or mainframes, but now, the computing power of hanson-1 chip is quite powerful and can fully meet the needs.

What are the advantages of computer design?

Of course, there are too many. In short, if you modify a part, you can change it directly on the computer. After modification, you can also calculate whether it is consistent with other parts through the computer.

After completing all the design, a trial assembly can be carried out on the computer, which greatly saves time and labor cost.

Otherwise, if you modify a part, you don't know how many drawings to change.

"Now, our telex operating system has matured, so we want to use digital telex control in the newly developed J-11."

Hearing what Lu said, Qin Guan frowned: "are you sure?"

In the current era, telex control is also an advanced technology. Even Eagle country only adopts telex control on the latest F-16. This technology can greatly improve the maneuverability of fighters, but it also contains great risks.

When developing fighters, the West almost always stumbled over the Telex system.

Now, the Han country has also begun to use a large number of j-14, but telex is used in the pitch direction. J-10 is already a stable three-axis four redundancy digital telex.

It's not just transplanting the J-10. The flight control rates of the two aircraft are different.

"Although it is reverse mapping, we have also carried out a large number of wind tunnel experiments on this aircraft and are finding out its control rate step by step." Lu said: "what we need is a third-generation aircraft that is ahead of the times. If we surpass it on the third-generation aircraft, we must take risks."

Lu is always stubborn and radical.
