Chapter 1201: How to solve the electromagnetic compatibility problem

Those who design warships are of course only responsible for the overall design. It is impossible to research and develop each of the subsystems. In this case, what a huge organization is the 7701 income.
They are mainly responsible for the integration of various systems.
What ordinary people see is what is installed on the surface, but as a warship designer, you have to see through the entire structure.
Apart from other things, such as naval guns, what everyone can see seems to be the turrets and barrels on the deck, but in fact, under the deck, there is a larger mechanism than the turret. How the shells are loaded Yes, how the whole system rotates, etc. There are a lot of equipment inside.
For another example, everyone can only see where the chimney is, but the designer has to think about how the chimney's flue should be deployed, where and where to go, how the pipelines in these spaces go, and so on.
Now, this is only the first meeting, which is also very important, because then everyone will design and develop according to Qin Guan's model.
Director Pan looked the most carefully. After reading the anti-aircraft missiles in front, he felt that he was most at ease here. In particular, there was an automatic reloading system at the back. After the shooting was completed, the automatic reloading was even more difficult. Up.
How to solve the accuracy problem of automatic loading on the swaying sea, etc.
"There is also this near-anti-cannon. It is said that the rate of fire is amazing. It must have a restriction mechanism and cannot shoot onto our own deck."
If you don't limit it, if you turn around and shoot on your own deck, you don't know how much damage it will cause.
Qin nodded in view.
Director Pan frowned more and more looking at various weapons.
"Naval guns must have artillery sighting radars, air defense missiles, and air defense radars. This kind of close-in guns must also have their own radars, anti-ship missiles, radar guidance, and long-range sea and air search radars. , There must also be a satellite communication system. In this case, there will be nearly ten electromagnetic radiation sources on our small warship. The interference between these electromagnetic radiation sources is probably a big problem."
This has not been done before. The first generation of Luda level did not have much electromagnetic equipment. Now, with so many, what should be done?
No matter what era, the interference and compatibility of various electronic devices on warships are a big problem.
Director Pan deserves to be a graduate of the Department of Mechanical and Electrical Engineering, and he can see the problem at this glance. This problem is also the most troubled Qin Guan.
There is no mature plan to learn from. Although Qin Guan can find the design drawings of the later 053H Jiangwei-class frigate, the electronic equipment is different. The current development of his own has even exceeded the later 90s. At the same time, in this case, the problem of electromagnetic interference is a big problem.
How to solve?
"Establish a land-based simulation experiment model. All systems should be docked and debugged on land first." Qin Guan said: "In this way, in the design stage, we can solve a large number of problems and save it after loading. Endless debugging."
When Qin Guan said this, Director Pan's eyes suddenly lit up: "Yes, why didn't we think of it?"
Establishing a land simulation model, using cement to build it, is definitely less expensive than a warship. Put all kinds of weapons on it, let’s test it first!
Qin Guan was amused when he heard it. This method was actually proposed by Director Pan.
In the history of that parallel time and space, in the mid-1980s, Director Pan served as the chief designer of the second-generation Type 052 guided missile destroyer in China. He boldly adopted the latest domestic scientific research results, established a land test field, personally presided over the docking and debugging of weapon systems, and solved a large number of technical problems; and on the basis of the 051 guided missile destroyer, he continued to strengthen the "system engineering" design concept for design, emphasizing The various systems of the ship are organically coordinated, and the overall performance is excellent. For the first time, the weapons and electronic systems and equipment on the ship form a combat system to realize the automation of combat command. The formation of the combat system has taken an important step in the development of ship combat command and control.
The benefits of the land proving ground are really too great, so when the aircraft carrier was built later, everyone followed the same pattern and built a cement aircraft carrier of the same proportion.
What is this aircraft carrier doing?
It is good to verify whether the design is reasonable, whether the various systems on the bridge are compatible, and so on!
This is essentially the same as making wooden models for fighter jets, but in the navy, the ones made are quite tall.
At the same time, electromagnetic compatibility can also be solved in this way.
Back then, the Type 052 guided missile destroyer had many electronic equipment and various antennas. How could the electronic equipment on the ship not interfere with each other and be compatible? Director Pan organized a research team to analyze various possible reasons for the poor anti-interference effect, lined them up, and tested them one by one. Finally, a new source of interference was discovered among hundreds of suspicious reasons. .
After repeated research and debugging, they have overcome the problem that satellite communications and radar are turned on at the same time without interference.
The chief designer of our warship was originally engaged in electromechanics. This is the biggest advantage. Therefore, although it is difficult, Qin Guan believes that Director Pan can definitely solve this problem.
Director Pan also agreed with Qin Guan's ideas. The construction of a land proving ground must start as soon as possible. After all, if this kind of warship is to be built within a year, the design and commissioning must be completed as soon as possible.
One problem after another, there is a solution now. Director Pan has continued to have questions since the beginning, and gradually became confident.
When he finished thinking about the weapon system, suddenly he thought of something: "What kind of power system does the order placed abroad require?"
The power system is the heart of the warship and the weakest place in the country. Now Director Pan wants to know what to do with the power system.
There are only steam turbines in China, so do we need to get boilers?
"There is no need to worry about the power system at the moment. All of our customers have chosen outsourcing." Qin Guan said: "Some choose Hansi's diesel engines, and some choose Yingguo's LM2500 gas turbines. We just use these machines. After practicing, we will selectively install diesel engines or gas turbines on the warships we build ourselves."
The power plant is the heart of the guided missile destroyer. Director Pan also encountered this situation when he was designing the Type 052 destroyer. At that time, advanced foreign guided missile destroyers used gas turbines, but domestic only steam power, which greatly affected the maneuverability and flexibility of warships. .
At that time, Director Pan was also the one who rejected all the opinions and used foreign equipment on the power plant of the second-generation guided missile destroyer.
Therefore, Qin Guan didn't worry, Director Pan would definitely be able to solve the problem of power unit coordination. Anyway, he used foreign warships to train his hands. In the future, when one's own country builds its own battleship, it will be easy to find how to match it.
