Chapter 979: Top King

The performance of the Black Hawk helicopter is definitely the best, but the price is also leveraged. After this time, Qin Guan reduced the unit price to 5 million eagle yuan, which is already acceptable.
Although Qin Guan can exchange more gold by relying on the system, if he spends a lot of money and is like a local rich man, it will have a bad impact on the international community. Even the local rich man will have to change when he goes out. Cheng Grande, that's it.
The price of the Black Hawk helicopter is very suitable. You can buy a batch in China. As for the surveying and copying of the Black Hawk, it will inevitably encounter great difficulties. We should start with the A109 helicopter and develop our own helicopter industry. .
During this period of time, Qin Guan has been busy with the introduction of helicopters. In a blink of an eye, it has already entered April. Just after signing a contract with Sikorsky to import fifty Black Hawk helicopters, there is a new piece of good news. Has arrived. The Kidd-class destroyer has returned!
These four destroyers are the biggest breakthrough of the Han Chinese Navy in recent years. From the 3,000-ton Luda-class destroyer to the 10,000-ton destroyer!
Now, the biggest threat to the motherland is the North. Therefore, these four warships will join the North Sea Fleet and their station is in Bencheng.
This was the most important moment for the Navy, and Qin Guan was definitely going to join in the fun.
Qin Guan had already been to Bincheng last time. At that time, Qin Guan also exchanged the 022 guided missile speedboat. He didn't know how well the navy surveyed and imitated it. Now, I happened to have a look together.
By the way, there is an inertial navigation system! Qin Guan thought of the original personal promise, but during this period of time, he has forgotten it.
The accuracy of the inertial navigation system is of great importance. It is not only required for nuclear submarines, but also for fighters, missiles and the like. If advanced laser gyros are available, it will certainly greatly improve the country's high-tech level.
At present, the liquid floating gyro is still used, which is an order of magnitude away from the advanced laser gyro.
In terms of domestic navigation system development, mainly the 7707 Institute. With the assistance of relevant units, after long-term and arduous efforts, they finally equipped the first missile nuclear submarine with an inertial navigation system and a starlight navigation system for correcting accumulated errors in inertial navigation. And satellite navigation system.
As for the leader in the development of gyros, it is Professor Lin.
Professor Lin, born in 1913, after being famous, his father was once the pioneer of the most important revolution to overthrow that feudal society, and he was also the most authentic person in the Capital University of Aeronautics and Astronautics.
He graduated from the Electrical Engineering Department of Huating Jiaotong University in 1935. In 1939, he received a Ph.D. in Aeronautical Engineering from the Department of Aeronautics, Massachusetts Institute of Technology, Eagle Country.
He is the founder of aviation automatic control discipline and gyro inertial navigation discipline, so he is also known as the king of gyro.
Now, Professor Lin is almost 70 years old, but he still works in the front line, for example, he continues to teach in the University of Aeronautics and Astronautics.
Without disturbing others, Qin Guan quietly walked into the Capital University of Aeronautics and Astronautics. The spring breeze blew and the big trees made a rustle, and there was a vibrant scene everywhere.
Qin Guan rarely comes to university, because after coming here, he always feels his superficiality. The proud children here are the true pillars of the motherland. As for himself, that has the advantage of the system in his brain.
The outside of the teaching building was covered with creepers. With the arrival of spring, countless green teeth began to spit out on the withered branches and vines. At this time, inside the teaching building, the voice of the professor was lecturing.
Qin Guan walked in slowly through the back door and sat in the last row.
At the table, Professor Lin is the one who has a big face, wears black-rimmed glasses, and his hair is gray. He wears a Chinese tunic suit, washed out, but very clean and tidy.
"This is the method of finding the complex roots of the real coefficient algebraic equations. I hope everyone can keep it in mind." Professor Lin said, after drinking, he heard some students talking below.
"Professor Lin, this method of yours is great. Compared with other methods, it avoids complex number operations and greatly simplifies the problem solving steps."
Classes in colleges and universities are different from middle schools and elementary schools, especially some experienced old professors who give lectures at will, and students can speak freely.
Now, Professor Lin's class is like this.
Hearing what this student said, Professor Lin was very proud: "Yes, this is our high-order equation splitting the root method. Now, let's practice a few more and master the following."
"Professor Lin, I heard that this solution is named'Lin method' in the international mathematics circle, is it true?"
Professor Lin drank the water on it, and when he heard this, his face was full of smiles: "Yes, it was in 1938. At that time, I was 25 years old. This calculation method invented, now, this The method is not only for us to perform calculations on paper, but also for the calculations of the computer, using my method."
"Professor Lin, you are awesome, and we just want to be like you."
The students below all cast admiring glances. Lin Jiaoshu still had a smile on his face. Just then, he swept to a young man sitting in the back row of the classroom.
When Professor Lin was in class, he always attracted a lot of students. A large number of students from other departments came to observe, but everyone didn’t like sitting in the back row. Many of them moved a small horse to sit on the open space in the front row. In order to see more clearly, Qin Guan seemed abrupt when he was there.
Qin Guan was immediately embarrassed when he was seen by Professor Lin like this. To tell the truth, when I was in college, I didn’t study hard for this high-order equation. forgotten.
Now, looking at the deductions on the blackboard, I really can’t remember.
"Okay, let's end today's class." Professor Lin finished speaking and walked slowly towards the back.
Qin Guan stood up: "Professor Lin, you are really good."
Young Junjie, Professor Lin is also admirable throughout his life. In Eagle Country, he gave up his high-paying job and returned to the motherland resolutely. He contributed his life to the aviation industry of the motherland and made outstanding contributions to the navigation system.
"No, you are old, President Qin, you are truly young and promising." Professor Lin said.
Qin Guan was suddenly surprised: "Professor Lin, do you actually recognize me?"
Although Qin Guan presided over a lot of work, for the sake of Qin Guan's safety, the country deliberately kept a low profile. Who would have thought that he would be recognized by a professor in the university.
This is so strange.
"President Qin, I have been waiting for you for a long time." Professor Lin said, "Let's go, go to my office and talk."
