Chapter 168 Competition with Zhongjiang Shipyard
Active phased array radar and passive phased array radar differ by one word, but they seem to be almost the same. In fact, the principles of the two are quite different.
Phased array radar works by changing the phase of radar waves, so there is no need to rotate the antenna. In theory, if it is fixed there, it can cover the entire sky in front, and the limit can even reach 180 degrees.
However, the passive phased array radar, like the previous antenna, still uses a waveguide to emit electromagnetic waves, but a large number of phase shifters are installed on the front plate to change the phase of the electromagnetic waves.
Active phased array radar is composed of T/R components. Each component is an independent radiating and receiving unit. It is a semiconductor product.
The individual power may be very small, only a few watts or dozens of watts, but when thousands of units are combined together, the power is quite powerful.
Due to the simple technology of passive phased array radar, this type of radar is currently installed on warships, whether it is Lao Maozi or the United States.
However, if the country wants to catch up and surpass, it must bypass the passive phased array radar stage and directly develop active phased array radar.
This is a difficult process of catching up and surpassing. With limited funds, there are many uncertainties from the beginning of the project. However, no matter what, with Ben Lao leading the team, the 14th Institute will definitely overcome obstacles and pioneer and innovate. Keep moving forward until we finally develop qualified products.
At this time, when the material of the T/R component was mentioned, Mr. Ben was also very emotional.
"We are conducting a principle analysis and we should be able to make gallium arsenide components. However, the yield rate will be very low and the production cost will be high. The cost of silicon bipolar transistors can be reduced, but the performance of this component is not good. "
“Then two components can be combined together. In an antenna array, one-third of gallium arsenide is used to improve performance, and two-thirds of silicon bipolar transistors are used to reduce costs.”
Lao Ben opened his eyes wide again, this is really the case! Unexpectedly, Mr. Qin's few words could really show them a way.
“Mr. Qin, it would be great if a talent like you could come to our 14th institute.”
“I’m just talking on paper.” Qin Tao said.
"Mr. Qin, don't hide your clumsiness. Everyone knows your abilities. The relevant units have been struggling for so long to solve the helicopter landing system. You went up and found two wrongly connected wires in a few minutes. ." Mr. Ben said: "Your ability has long been spread in our circle. If we encounter any difficulties in research and development in the future, you will have to lend a helping hand!"
Qin Tao was embarrassed for a while. Those things were really made by me. I am a time traveler! Of course we know that we connected two wrong wires, but we are laymen when it comes to developing the most critical phased array radar!
However, looking at the current situation, no matter what Qin Tao says, the other party will not believe it.
"Yes, Mr. Qin is a capable man." At this time, the two of them were walking and talking. When they entered the cafeteria, someone happened to approach and interrupted, but the words were strange.
Qin Tao glanced at the other party: "Who is this?"
“President Qin is famous, I’m just a nobody.” The other party continued.
“Mr. Qin, this is Ma Guoqiang, the director of Zhongjiang Shipyard. He is sitting in the area where the person in charge of your shipyard is. Don’t you recognize him?” Mr. Ben asked.
Zhongjiang Shipyard?
Qin Tao realized that it was the factory that stole his own design drawings and then built substandard missile boats.
“Director Ma, you are a veteran in the system, please forgive me for my blindness.” Qin Tao was very polite.
“Young man, you also know how to respect the old and love the young. So, tell me, what’s so weird about the design of the missile boat?” Ma Guoqiang looked like he was relying on his old age.
"Missile boat, design drawing? Didn't you design it yourself? Why do you ask me what's weird?" Qin Tao glanced at him: "Did you steal our design drawing?"
"What is stealing? In the past, the design drawings were shared by everyone, and whoever had the production capacity would produce them!"
“That was before, Director Ma. Times have changed. If you don’t change, living in the past world is pitiful, sad and deplorable!”
“What did you say? Huh, young man, you are so arrogant, you can’t survive in this system!”
Qin Tao glanced at him: "I can't survive? Do you know who my dad is?"
“Your dad? Isn’t your dad the old factory director Qin Baoshan? Huh, if it were him, he would definitely give us the drawings!”
Qin Tao gave him a look of disdain. You don’t even know who is behind me, and you actually said that I can’t survive? As expected, I can't communicate with the self-righteous old retard.
He wanted to know the problems in the design drawings, how could he tell him? Did you tell him and wait for him to **** the missile boat order from you?
Even when Wu Shengli asked, Qin Tao didn't say anything.
The work he had to do was actually very simple. In the set of drawings submitted to the ship design institute, he reduced the cross-sectional area of the water jet propulsion channel by one-third!
The water jet thruster cannot absorb enough water flow, so of course it cannot output at full power. However, that thing is inside the hull of the missile boat. After welding, only by cutting it can we know how big the water channel should be. Thick.
Can the Navy’s missile boats be separated from Zhongjiang Shipyard for research? Of course it's impossible. At most, it's just a look at the appearance. From the outside, nothing can be seen.
The 022 missile boat relies on speed to win. The missile boat produced by Zhongjiang Shipyard according to the artificial drawings is not fast enough, so of course the navy does not want it.
During this period, Ma Guoqiang did not know how many people he had contacted for research. However, none of the domestic ship designers had ever been exposed to waterjet thrusters, so it was impossible to know the weirdness in them. Only Qin Tao knew the secrets inside. .
Ma Guoqiang wants to know? Dream on!
Ten years from now, twenty years from now, when the Navy no longer needs the 022 missile boat, it will not be too late to tell him.
Qin Tao did not continue to talk to Ma Guoqiang. This guy has a brain disease and needs to be cured.
Ma Guoqiang stamped his feet and huffed angrily. In fact, he also knew today that Qin Tao might not tell him, but he had no other choice. Their shipyard specializes in building military ships, so he had to try. In the end, he hit the wall without a doubt. .
For other people, eating is secondary. During the meal, communicating with each other and reaching various agreements are the main thing. However, Qin Tao is not familiar with them anyway, so he will eat first before talking.
However, soon, Mr. Wu, Mr. Pan, and Mr. Ben all came close and sat next to Qin Tao.
Many people looked envious. These people are all leaders in the industry! How could Qin Tao, a young man, be appreciated by so many people?
If it weren't for Mr. Wu today, Qin Tao wouldn't have a chance to speak at all!
afternoon.
“After careful study, we believe that the plan of the 14th Institute is more in line with the needs of our navy.” Sure enough, a navy leader spoke, and at noon, after their discussion, they finally reached a consensus.
The people in 23 all looked very ugly.
“In the next meeting, our shipbuilding industry will speak and think about the development of our future destroyers.” Wu Shengli said: “First of all, let Mr. Pan speak.”
As the designer of two destroyers, Mr. Pan has a lofty status in the warship industry. At this time, he deserves to speak.
"We are currently building two Type 052 destroyers, which will play a role in the development of our warships. However, due to the embargo problem of the above power system, this destroyer will not be able to continue to be built. Next, if we want to continue If it develops, then we can only use the four gas turbines obtained from secret channels to continue to build two destroyers. Based on the power of these gas turbines, two destroyers can drive five to six thousand tons. Therefore, the next destroyers, I think it is more appropriate to enlarge the displacement to five to six thousand tons, and if the ship is well designed, it can be increased to more than seven thousand tons."
The four Lao Maozi gas turbines are no longer a big secret and have been spread in the industry. However, how these gas turbines were obtained is still a secret.
This also means that they can build two more warships in the future. These two hard-won warships will become the objects of competition for countless shipyards!
"Dear leaders, please give this glorious task to our Zhongjiang Shipyard!" Ma Guoqiang couldn't help but say: "Our shipyard has a long history and has built many warships for the navy. We will definitely be able to complete this task now. !”
"Everyone should already know." Wu Shengli said: "Only through competition can progress be achieved. Therefore, the Navy has passed relevant decisions. From now on, the Navy's warships will be designed through competitive bidding. The Navy is only responsible for formulating the basic parameters. For everything else, relevant departments need to provide design plans and specific drawings, and then our Navy will decide.”
The bidding method has been laid for a long time. In the past few months, many shipyards have opposed it, and they even went to their superiors.
However, with the navy's firm attitude, this plan was approved by the superiors. From then on, it was impossible to express determination and ask for orders while crying about one's difficulties.
“Dear leaders, our Zhongjiang Shipyard has entrusted the Ship Design Institute to design a product for us. Now, I would like to speak.” Ma Guoqiang continued.
Of course he also knows about the bidding, so he has made preparations in advance.
“Okay, let’s ask Director Ma to introduce us.”
Turning on the slide projector, Ma Guoqiang solemnly took out his own slide and inserted it on it. On the screen, a beautiful-looking warship appeared in front of everyone.
"The hull of our warship is enlarged by the mature 051 destroyer, so we call it the 051B destroyer. It has complete air, sea and ship attack capabilities."
Qin Tao sat there and looked at this destroyer with interest. Yes, it was really 051B.
At the bow of the ship are twin-mounted naval guns, behind them are Sea Sidewinders, behind the chimneys are anti-ship missiles, and finally there are helicopter hangars and take-off decks.
The overall design is pretty good, after all, it is a product of a ship design institute.
It seems that Zhongjiang Shipyard is in a hurry. They also know that if they can't receive orders from the Navy, their shipyard will be on the verge of collapse. However... they seem to have forgotten what the Navy urgently needs right now!
Ma Guoqiang talked non-stop for more than half an hour.
When the Navy decided to use competitive bidding to determine the next warship construction, Ma Guoqiang once strongly opposed it. In the past six months, he has been active in the capital, lobbying various leaders, trying to get the Navy to give up.
After the plan was finally implemented, Ma Guoqiang immediately went to the Ship Design Institute and commissioned the design. In short, no matter what, he must get this order, which was related to the life and death of their shipyard.
Other large shipyards along the coast have construction contracts for foreign cargo ships. Therefore, they can survive even if they do not need the order for these two warships. The Zhongjiang Shipyard is different. Due to geographical restrictions, if they take it Foreign cargo ships of 10,000 tons, even if they are built, will not be able to sail at all!
They can only grab the contract for these two destroyers. Even if they used to build missile boats, they still want to build destroyers now!
“Are there any other plans for other shipyards?” Wu Shengli asked.
“We, Mingzhou Shipbuilding Industry Group, also have a special design plan for an air defense ship.” Qin Tao stood up: “Since the product of the brother unit is called 051B, then let’s call ours 051C!”
“Air defense ship? Are you planning to use Sea Sidewinder or our Hongqi-61?” Someone was immediately curious.
At present, these two models are the only ones that have matured in China. However, they seem to be useless and cannot bear the title of air defense ship.
“Neither.” Qin Tao answered as he walked up.
“Should we use the new model from our Second Aerospace Institute? This model is still a few years away from being successfully developed, right?”
“Nor.”
After Qin Tao answered this question, he walked to the slide projector and put up the slide he had hastily drawn. When the image on the screen became clear, everyone was shocked.
“The firing mechanism of a revolver?”
“Look at the thickness, is it the launch tube of the S-300 missile?”
“Is that flat panel at the back a phased array radar?”
“Where’s the helicopter hangar? It’s unscientific!”
"Cough, cough." Qin Tao coughed and looked at the people below. When everyone calmed down from the surprise, Qin Tao said: "Our warship is called a professional air defense destroyer. Therefore, our warship mainly does One thing is air defense! It will provide the navy with the 100-kilometer-level air defense firepower network it needs most!"
