Open an aircraft carrier to fight against Japan

Different from the speed measurement method used by the Portsmouth shipyard in the United Kingdom, the Lushun shipyard uses a radar speed measurement with higher accuracy. The engineering and technical personnel put a speed measurement radar on the shore of the radar speed measurement area. The speed measurement radar is the most accurate Simple radar, just need to measure the speed. In modern society, traffic police use this kind of radar to catch speeding cars.

When a warship passes through the speed measuring area, the radar can measure the speed of the warship. The speed test of the warship that Lin Yuan visited in the UK was specially arranged by the British side to demonstrate the advanced performance of the dreadnought ship. It was not against the ship at all. For performance testing, if you want to fully test the speed characteristics of a warship, you need to conduct multiple tests at different main engine speeds.

Lin Yuan was in the command room, watching Captain Wu Xinghai pick up the walkie-talkie of the ship's communication system, and ordered loudly: "The speed of the main engine is 5.00%, and pass the radar speed zone." Lin Yuan heard this order, and subconsciously raised his head to look at the ship. The comprehensive display screen in front of the leader shows the working status of each system, and the speed on it drops quickly.

When the warship is sailing, the speed of the main engine is about 80.00% of the maximum speed, which is the most fuel-efficient. Therefore, when the ship sails from the mooring area to the radar speed measurement area, it always travels at 80.00% of the maximum speed of the main engine. Now reduce the speed of the main engine to 5.00%, Lin Yuan obviously felt that the warship slowed down. He looked at his watch and found that the speed slowed down very quickly, which shows that the warship's acceleration and deceleration characteristics are very good.

The warship quickly passed the radar speed measurement area. At this time, the radar control room sent a message. During the driving process just now, the speed of the warship was about two knots. Wu Xinghai ordered: "The warship turns at the limit radius and returns to the speed measurement area."

Lin Yuan thought: "Ultimate radius turn? This is a good opportunity to observe the maneuverability of the warship!" The warship quickly accelerated and turned 180 degrees in the sea. Lin Yuan estimated the diameter of the turn, which was about 500 meters The turning diameter of the warship is about four to five times the length of the hull. The captain of the Xiaofeng Ship is 160 meters, and the turning diameter is more than three times the length of the captain. This shows that the performance of the Xiaofeng Ship is excellent.

The mocking windship turned back to the speed measurement area, and drove through the calculation area again with 5.00% of the main engine speed, and then turned back to increase the main engine speed. The whole test lasted for a day, and the test ended at 35 o'clock in the evening. The test data showed that, The maximum speed of the Xiaofeng ship not only fulfilled the design target, but also slightly exceeded it, reaching [-] knots, and its economic speed was also [-] knots.

Wan Ling asked Lin Yuan: "How is it? The maneuverability of our new warship is pretty good, right?"

Lin Yuan smiled and said: "Very good, but our test is carried out in the offshore, the sea conditions in the offshore are stable, and many problems of the warship cannot be seen. When will we conduct the test in the open sea?"

Wan Ling said: "Tomorrow we will conduct a high-sea test, and it is expected to sail to the Yellow Sea, about [-] nautical miles away from our Lushun base, and we will set off at two o'clock in the morning tomorrow. Only by sailing at night can we inspect the level of the warship. .”

Lin Yuan asked: "Are you ready for the escort work? There are often Japanese warships in the Yellow Sea. What if we encounter them?"

Wan Ling said: "We have arranged for the Jingzhong Ship and the Zhongrui Ship, and Captain Deng Shichang will escort us."

Lin Yuan asked, "Apart from nautical experiments in the Yellow Sea, do we have any other subjects?"

Wan Ling said: "We will also conduct some experiments on the performance of the radar. There are many merchant ships in the Yellow Sea, which happens to be a good opportunity for us to detect."

Lin Yuan knew the test plan for the next day, so he stayed on the warship. When Deng Shichang came to the mock wind ship that night, he was accompanied by radar expert Ma Zhiliang. Deng Shichang laughed when he saw Lin Yuan. Said: "I saw our new warship, it's very beautiful, I don't know when will it be enough for me to command this kind of warship?"

Lin Yuan thought to himself: "There are many technologies on the warship that are beyond the times. These technologies are enough to change the original rules of naval warfare. If I let you command a new type of warship now, you might use it as an ordinary gunboat." Lin Yuan smiled and said: "This kind of warship has many advanced technologies, so you must learn these technologies first."

Deng Shichang said: "Okay, then I will learn these techniques, and when I pass the examination, I will personally command a warship."

After the two laughed, Deng Shichang returned to the Jingzhong ship, and the Xiaofeng ship set sail immediately, and arrived in the Yellow Sea area three hours later. Ma Zhiliang said to Lin Yuan and Wan Ling: "Let's go, go to the radar control room." The three of them were talking, accompanied by Tao Zheng, political commissar of the mocking wind ship, to the radar control room. Tao Zheng was originally the head of the UAV regiment on the Beijing ship, and was always in charge of the special staff department in the war commanded by Lin Yuan. An important member of aviation reconnaissance, this time the mock wind ship needs a political commissar, so Lin Yuan let him come.

When Lin Yuan came in, he felt that the radar control room was very empty, because there was only a long table in the huge cabin, and there was a big cabinet beside it, and the big cabinet was connected to the table by wires.

Lin Yuan asked, "Why is this room so empty?"

Ma Zhiliang replied: "This is the radar control room for maritime security. Because our radar is relatively small in power, the detection distance is only less than [-] kilometers, so the received data is relatively small, and the number of consoles is relatively small. When we improve the radar in the future, the data will increase, so the number of consoles will also increase, and those empty spaces are reserved for the consoles.”

"We haven't installed a fire control radar yet. When a new type of magnetron is developed in the future, we will install a fire control radar that emits electromagnetic waves with a higher frequency. After the target, the target distance, azimuth and speed information will be transmitted to the fire control radar, the fire control radar control room is not here, so we need to install additional information transmission components, that is, the data link system."

Lin Yuan walked to the back of the table while listening, and found that the table was full of dark green screens, and there were five or six rows of buttons below. Lin Yuan asked, "These are the radar screens, right?"

Ma Zhiliang pointed to those screens and said: "That's right, that is our radar screen. Since the picture tube technology is not very developed, all this radar screen cannot display full color." After Ma Zhiliang finished speaking, he saw Lin Yuan frowned. He thought Lin Yuan was dissatisfied with the performance, so he said: "Although full-color display cannot be realized, the performance is sufficient..."

Lin Yuan said: "That's not what I'm talking about. What I want to say is: Why is there no one in this cabin? Isn't it going to conduct a radar test? Why is there no operator?"

Wan Ling and Ma Zhiliang looked back at Tao Zheng when they heard this, but Tao Zheng was also helpless, Lin Yuan asked, "Who is the operator?"

Tao Zheng said: "It's Li Kai who was caught by you while playing games. I don't know where this kid has gone."

At this moment, he heard footsteps coming from outside, and a smiling officer walked in from outside, holding a paper bag in his hand, it was Li Kai, Tao Zheng frowned when he saw him coming in, and asked angrily: "Where did your kid go?"

Li Kai stretched out the paper bag in his hand and said, "I heard that the captain and some experts are coming to visit. Isn't it time for breakfast? I went to buy you a drawer of steamed stuffed buns specially, Captain, Don't be angry, try one first?"
