Chapter 1013 Gyro

"Not only do you have to build it, you also have to be responsible for training the comrades who come to study at the Yuedong Shipyard. If the first step goes smoothly and all the standards are met, we will move east and south at the same time."

The Navy and the Naval Equipment Bureau are very satisfied with this frigate, whose design indicators are extremely high at first glance. As long as it is basically manufactured to meet the design indicators and there is enough manufacturing experience, the two sides will prepare to build it together and strive to produce a certain number as soon as possible.

Fortunately, the enemy's naval and air forces were severely compressed in the strait in the middle of Danggui Province. It was not like what Gao Zhendong knew in his previous life. Because it was not navigable, all the ships of the Southern Fleet had to be built in eastern Guangdong, and all the parts had to be transported by train.

Now we can build it wherever we want, and the mutual transfer among the three sea areas is not a problem at all.

"Well, don't worry, we have made all the preparations. The comrades from Guangdong East Shipyard are here with us, just like they are in their own factory. We will teach them until they learn it. If they don't, we will dispatch another group of comrades to support them in the early stage." The comrades from Songjiang Shipyard said with a smile.

"Okay, then we'll wait for your good news." The comrades from the Marine Equipment Bureau were very optimistic about the construction of this ship. This ship is not big, nor complicated, so it shouldn't be slow.

In fact, the original Type II frigate took only a little over a year to build during those difficult times. The reason why it was built slowly in later generations was that they had to consider the overall renewal plan. In fact, if the production capacity was really increased, this type of ship weighing more than 1 tons could be built much faster.

The comrade from the Ship Research Institute smiled and said, "You can wait for good news now, but we still have bigger and more difficult tasks waiting for us."

The comrade from the Naval Equipment Bureau knew what he was talking about and laughed, "It's a good thing to have a mission. As for the specific details of this matter, we still suggest that you go to Beijing before officially starting. I think you will gain a lot. At least you can grasp the latest developments in electronic technology and plan the configuration of shipborne electronic equipment in advance."

"Well, we will definitely visit Comrade Gao Zhendong before we start the design." Everyone knows that Comrade Gao Zhendong has many ideas, both in terms of planning and specific technical details, and has provided a lot of suggestions and technologies, which have been of great help in the renewal of this batch of navy ships. Some of them are even decisive.

It's better to take a chance and ask.

Thinking about the new shipborne radar that is becoming more and more promising at the Ship Electronics Research Institute, the comrades at the Ship Research Institute are very excited and they must go and take a look at that place.
-
Gao Zhendong didn't know about this good news. At this moment, he was looking at a report in his hand with a happy expression on his face, concentrating on it.

Sitting in front of him was Mr. Mo, a comrade from the original research institute, who was responsible for the specific work of the laser gyroscope.

At this moment, his face was full of joy: "Chief Engineer Gao, after more than two years, I finally lived up to your expectations and finally made this thing."

In addition to the materials in Gao Zhendong's hand, there was also a box in front of him containing a device.

At first glance, it looks like an equilateral triangle of glass. There are some accessory devices installed in the corners and the middle of the glass block, and some cables are connected. It looks that simple at first glance.

But Gao Zhendong knew that this was the current domestic laser gyroscope, and it was also the top product of laser gyroscopes in the world, and it was absolutely leading. According to the time calculation, the Citigroup should have made the first laser gyroscope experimental device by now, after all, that thing was made in February 63. However, regardless of the accuracy of this device, its total optical path length was 2 meters!
If this thing is used on a missile, I'm afraid everyone will flip the table.

Truly practical gyroscopes appeared between 1972 and 75. There is no standard date for the exact time, but they were first used on airplanes in 1975.

The gyroscope in front of Gao Zhendong is the only practical laser gyroscope in the world, and it will remain so for a long time to come.

The principle of this thing is known to all major countries in the world, but it took almost ten years before it was made truly practical.

"Chief Engineer Gao, you see, after our efforts, the zero drift, resolution, scale factor, dynamic range and bandwidth of this gyroscope can meet the current needs, and even greatly exceed them. It is the highest performance laser gyroscope in the world..."

At this point, Mr. Mo even laughed. Currently, only this company has this thing. Even if he makes it out of shit, it will be of the highest quality.

However, according to the absolute values ​​of the actual performance of this gyroscope, it is definitely not inferior to other gyroscopes, even the best air-floating, liquid-floating, and magnetic-floating mechanical gyroscopes currently available.

Forget it, there’s nothing good to brag about this, let’s find something else to brag about.

"It has a volume of 18*19*5cm and weighs 3kg. Compared with the suspended gyroscopes with the same accuracy, its volume and weight are greatly reduced. This means that the total weight of a set of three-axis gyroscopes does not exceed 10kg. This has great advantages whether it is used in inertial navigation platforms or strapdown inertial navigation systems."

For a high-precision mechanical gyroscope, it must have a large enough moment of inertia and a small enough rotational friction. Otherwise, the gyroscope's zero-point drift alone can directly guide a missile or aircraft into the sky, let alone its resolution. Zero-point drift is the most important indicator of a gyroscope, even more important than resolution.

The reason why the V-2 missile had poor accuracy was because it used a ball bearing gyroscope, which could drift up to 15 degrees per hour. If it hadn't flown close, its accuracy would not even be as good as that of an unguided rocket. The reason is simple: it's better not to command blindly than to command blindly. In this case, it is necessary to use air suspension, liquid suspension, or even magnetic suspension technology. Once these technologies are used, the weight and volume of a single set of gyroscopes will increase rapidly.

A set of high-precision three-axis gyroscopes, even without the inertial platform, weighing hundreds of kilograms is commonplace.

Moreover, another problem for us is that there are no high-precision mechanical gyroscopes at all!
"Boss Mo, have you submitted this for acceptance?"

"Not yet. You will definitely be the leader in the acceptance. However, some comrades have already requested a few, and I produced them a few days ago for them to take away. Hahaha." Thinking of the anxious looks of the comrades who were working on missiles, President Mo smiled unusually happily.

The production speed of this thing can't be increased at present, but even if it is done manually, it will not be a problem to supply the newly produced long-range missiles, fighters and bombers. After all, the production of these things can't be increased quickly.

"I think it's ready. Let's submit it for inspection. With this set of equipment, our planes and missiles can finally find their way on their own."

This thing can be used not only for missiles, but also for airplanes and ships. However, ships have relatively more means to determine their own positions, and the requirements for accuracy and positioning speed are relatively low, so this kind of advanced stuff is probably not needed for the time being.

"Okay, if you think so, then let's take care of this matter. It's finally bearing fruit, haha." Mr. Mo came here this time just for this matter.

After that, he said to Gao Zhendong: "By the way, we have written an article about this thing, and you are the corresponding author. Here is the article. Take a look. If there is no problem, we will send it out later."

Gao Zhendong had no objection to publishing the article. In fact, the principles and some technical details of the laser gyroscope were known to several major countries, but no one had been able to figure it out in advance.

It is not easy to restore this thing based on the paper as long as most of the technical details are erased or processed.

The comrades from the original research institute got all the theories, derivation details and processes, and with Gao Zhendong's occasional help, it took two or three years to develop this thing. You can imagine how difficult it was.

"Has the Defense Work Committee agreed?" Gao Zhendong asked with a smile.

"The Defense Work Committee has discussed this with our Academy of Science and Technology and they agree. In addition, many comrades from various parties helped us to desensitize this article. There is no problem in this regard. As for whether the Defense Work Committee agrees that your name should appear on the article, we have also asked for the Defense Work Committee's opinion. Because you are the inventor of the laser and a well-known scientist in the field of lasers, it is natural for you to appear in the field of laser applications, especially for the top-level achievements such as the laser gyroscope. It would be strange if you did not appear on the article. The Defense Work Committee also agreed."

If it doesn't appear where it should appear, then there is most likely a problem.

Gao Zhendong nodded when he heard this. Since all parties agreed, there would be no problem. In terms of scientific and technological strength, if they wanted to gain a certain voice, they still had to create momentum. It was estimated that several units had considered this issue.

He quickly glanced through the paper, signed his name and handed it back to Mr. Mo.

His main concern was whether there was any content that should not be disclosed, which was also the main purpose of Mr. Mo giving him the article for review.

As for the writing style, structure, foreign language translation, etc. of the thesis, Gao Zhendong is not as good as others in this aspect.

"What are your ideas for the next step?" Gao Zhendong asked Mr. Mo after signing.

"Idea? Just to improve this gyroscope." Mr. Mo was a little surprised. Isn't this a basic operation?

Gao Zhendong thought for a moment and said, "Well, I have some ideas. How about this? You can mention it during the acceptance. That way, there will be fewer formalities."

He whispered something to Mr. Mo and the others, who laughed with joy as they listened. Mr. Gao's operation was simply dazzling. Was he planning to finalize the next plan and funding in front of everyone during the acceptance?

"Okay, we'll go back and put it in the acceptance report as a research prospect chapter, and try to get the project approved smoothly."
