Different from the speed measurement method used in the shipyard of Portsmouth in the United Kingdom, the shipyard in Lushun uses a radar speed measurement with higher accuracy, and the engineering technicians put a speed measurement radar on the shore of the radar speed measurement area, the speed measurement radar is the simplest radar, only need to measure the speed, in modern society, the traffic police use this kind of radar to catch speeding cars.

When the warship sails through the speed measurement area, the radar can measure the speed of the warship, and the speed test of the warship that Lin Yuan visited in the United Kingdom was specially arranged by the British side in order to show the advanced performance of the dreadnought, and it is not a thorough test of the ship's performance at all.

Lin Yuan was in the command room, watching the captain Wu Xinghai pick up the walkie-talkie of the ship's communication system, and ordered in a loud voice: "The speed of the main engine is five percent, and it will pass through the radar speed measurement area." When Lin Yuan heard this order, he subconsciously looked up at the comprehensive display screen in front of the captain, on which there was the working status of each system, and saw that the speed on it quickly decreased.

When the warship is sailing, the speed of the main engine is about 80% of the maximum speed, which is the most fuel-efficient, so the mocking wind ship has been traveling with 80% of the maximum speed of the main engine when it sails from the mooring area to the radar speed measurement area, and now the speed of the main engine is reduced to 5 percent, 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 acceleration and deceleration characteristics of the warship are very good.

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

Lin Yuan thought to himself: "Extreme radius turn? This is a great opportunity to observe the maneuverability of the battleship! Lin Yuan estimated the diameter of the turn, about five hundred hundred meters, the diameter of the warship's turn was about four to five times the length of the hull, and the length of the mocking wind ship was 160 meters, and the turning diameter was more than three times the length of the ship, which showed the excellent performance of the mocking wind ship.

The mocking wind ship turned back to the speed measurement area, and then used five percent of the main engine speed to drive back through the calculation area, and then turned back, increased the speed of the main engine, the whole test lasted for a day, and the test ended at six o'clock in the evening, the test data showed that the maximum speed of the mocking wind ship not only completed the design index, but also slightly exceeded, reaching 35 knots, and the economic speed also had 18 knots.

Wan Ling asked Lin Yuan, "How is it?" Our new warship is not badly maneuverable. ”

Lin Yuan said with a smile: "Very good, but our test test is carried out in the near sea, the sea conditions in the near sea 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 test in the open sea, and it is expected to sail to the Yellow Sea, about 50 nautical miles away from our Lushun base, and our departure time is at two o'clock tomorrow morning, and we can only test the level of the warship by sailing at night." ”

Lin Yuan asked, "Are the escort work ready?" The waters of the Yellow Sea are often infaunted by Japanese warships, what if we run into 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, "In addition to the navigation test in the Yellow Sea, do we have any other subjects?" ”

Wan Ling said: "We will also test the performance of the radar, and there are many merchant ships in the Yellow Sea, which is a good opportunity for us to detect." ”

Lin Yuan knew that the next day's test plan was planned, so he stayed on the warship, and so on the same night, Deng Shichang came to the mocking wind ship, and he came with radar expert Ma Zhiliang, Deng Shichang saw Lin Yuan and smiled: "I have seen our new warship, it is very beautiful, I don't know when Lu Dao is more enough for me to command this kind of warship?" ”

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

Deng Shichang said: "Okay, I'll go and learn these skills, and when I pass the assessment, I will personally command a warship." ”

The two laughed, Deng Shichang returned to the Jingzhong ship, and the mocking wind ship set sail immediately, and arrived in the Yellow Sea three hours later, Ma Zhiliang said to Lin Yuan and Wan Ling: "Let's go, go to the radar control room and have a look." The three of them talked and went to the radar control room accompanied by Tao Zheng, the political commissar of the mocking wind ship, Tao Zheng was the head of the unmanned aerial vehicle regiment on the original Beijing ship, and he had always been an important member of the special staff department responsible for aviation reconnaissance in the war commanded by Lin Yuan.

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 large cabinet on the side, and the big cabinet had wires connected to the platform.

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

Ma Zhiliang replied: "This is the control room of the sea guard radar, because our radar power is relatively small, and the distance that can be detected is only less than 50 kilometers, so the data received is relatively small, and the number of consoles is relatively small. ”

"We have not yet installed the fire control radar, and when the new magnetron is developed in the future, we will install the fire control radar with a higher frequency of electromagnetic waves, and when fighting, the coast alert radar is responsible for searching and discovering the target, and after the target is found, the target distance, azimuth and speed information will be transmitted to the fire control radar, and the fire control radar control room is not here, so we also need to install information transmission components, that is, the data link system."

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

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

Lin Yuan said: "I'm not talking about this, what I want to say is: why is there no one in this cabin?" Isn't it a radar test? Why don't you see the operator? ”

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

Tao Zheng said: "It's Li Kai who was caught by you playing a game, I don't know where this kid ran away." ”

At this moment, I heard footsteps outside, and an officer with a smile on his face walked in from outside, holding a paper bag in his hand, it was Li Kai, Tao Zheng frowned when he saw him come in, and asked angrily: "Where did you kid go?" ”

Li Kai stretched out the paper bag in his hand and said, "I heard that the captain and several experts are coming to visit, isn't it time for breakfast?" I went to buy you a drawer of steamed buns, head of the group, don't be angry, try one first? ”
