Super Weapon Swap System

The performance of the Black Hawk helicopter is absolutely the best, but the price is also a lever. Qin Guan reduced the unit price to 5 million Eagle yuan, which is acceptable.

Although Qin Guan relied on the system to exchange more gold, if he spent money recklessly and was just like a local rich man, it would have a bad impact on the world. Even if the local rich man went out, he would have to become Ge Langtai.

The price of Black Hawk helicopter is very appropriate. We can buy a batch in China. As for the mapping imitation of Black Hawk, we will inevitably encounter great difficulties. We should start with A109 helicopter and develop our own helicopter industry first.

During this time, Qin Guan has been busy with the introduction of helicopters. In the twinkling of an eye, it has entered April. After signing the contract with Sikorsky to import 50 Black Hawk helicopters, a new good news has come. Kidd class destroyer, it's back!

These four destroyers are the biggest breakthrough of the Han Navy in recent years. They have jumped from a 3000 ton brigade class destroyer to a 10000 ton class destroyer!

Now, the greatest threat to the motherland is the north. Therefore, these four warships will join the North Sea fleet and stay in Bincheng.

This is the most important moment for the Navy. Qin Guan must go to join the fun.

Last time, Qin Guan had been to Bincheng. At that time, Qin Guan also exchanged 022 missile speedboats. I don't know how the Navy's mapping imitation is. Now, we just go to have a look together.

By the way, and inertial navigation system! Qin Guan thought of his own promise. He had forgotten it during this period of time.

The accuracy of inertial navigation system is of great importance, not only for nuclear submarines, but also for fighters and missiles. If there is an advanced laser gyro, it will greatly improve the country's high-tech level.

At present, the liquid floating gyro is still used, which is an order of magnitude behind the advanced laser gyro.

It should be said that the development of domestic navigation systems is mainly 7707 institutes. With the assistance of relevant units and after long-term and arduous efforts, they finally equipped the first missile nuclear submarine with inertial navigation systems, as well as starlight navigation and satellite navigation systems to correct the accumulated errors of inertial navigation.

The leader in gyro development is Professor Lin.

Professor Lin, born in 1913, his father was the pioneer of the most important revolution to overthrow the feudal society. He was also one of the most talented people in the Capital University of Aeronautics and Astronautics.

He graduated from the Department of electrical engineering of Huating Jiaotong University in 1935. In 1939, he received a doctorate in aeronautical engineering from the Department of Aeronautics, Massachusetts Institute of technology, Eagle kingdom.

He is the founder of aviation automatic control discipline and gyro inertial navigation discipline. Therefore, he is also known as the gyro king.

Now, Professor Lin is nearly 70 years old, but he still works in the front line. For example, he continues to teach in the University of Aeronautics and Astronautics.

Qin Guan did not disturb others. He quietly walked into the University of Aeronautics and Astronautics in the capital. The spring breeze blew, and the trees made a loud noise. There was a scene full of vitality everywhere.

Qin Guan seldom comes to the University, because after he comes here, he always feels superficial. The proud children here are the real pillars of the motherland. As for himself, he has the advantage of the system in the brain.

The outside of the teaching building is covered with Parthenocissus. When spring comes, countless green teeth begin to spit out from the withered branches. At this time, the voice of professors is coming from the teaching building.

Qin Guan slowly walked in through the back door and sat in the last row.

On the lecture table is Professor Lin. his face is very big. He is wearing black framed glasses. His hair is gray. He is wearing a Zhongshan suit. He has been washed old, but he is very clean and tidy.

"This is the method of finding complex roots of algebraic equations with real coefficients. I hope you can keep it in mind." Professor Lin said here. After drinking, he heard some students say.

"Professor Lin, your method is very good. Compared with other methods, it avoids complex operation and greatly simplifies the problem-solving steps."

Classes in Colleges and universities are different from those in middle schools and primary schools. In particular, some experienced old professors give lectures at will, and students can speak freely.

Now, Professor Lin's class is the same.

After hearing the student's words, Professor Lin was very proud: "yes, this is our splitting root method for higher-order equations. Now, let's practice more and master the following."

"Professor Lin, I heard that this solution is named 'Lin * * method' in the international mathematical community. Is it true?"

Professor Lin had finished drinking water on it. When he heard this, his face was even more smiling: "yes, that was 1938. At that time, I was 25 years old. I invented this calculation method. Now, this method is not only our paper operation, but also my method in computer operation."

"Professor Lin, you're great. We'll just like you."

The students below all cast admiring eyes. Professor Lin's face was still smiling. At this time, he swept to a young man sitting in the back of the classroom.

Professor Lin always attracts many students in class. A large number of students from other departments come to attend. However, everyone doesn't like to sit in the back row. Many of them move a small Mazar to sit in the open space in the front row, so that they can see more clearly. Qin Guan is abrupt there.

When Professor Lin looked at Qin Guan, he immediately felt embarrassed. To tell the truth, when he was in college, he didn't study hard. As a result, he forgot after the exam.

Now, looking at the deduction on the blackboard, I really can't remember.

"Well, that's all for today's class." Professor Lin said and walked slowly towards the back.

Qin Guan stood up and said, "Professor Lin, you speak very well."

Young Junjie, Professor Lin's life is also admirable. He gave up his high paying job in Eagle country and resolutely returned to the motherland to contribute his life to the aviation industry of the motherland, especially in the navigation system.

"No, old, Mr. Qin, you are really young and promising," said Professor Lin.

Qin Guan was surprised: "Professor Lin, do you recognize me?"

Although Qin Guan presided over a lot of work, the state deliberately kept a low profile for the safety of Qin Guan. Who would have thought that he was recognized by a professor in the University.

That's strange.

"President Qin, I've been waiting for you for a long time." Professor Lin said, "let's go and talk in my office."
