Yuanwang 3: the 100th time to the sea of stars ■ Ni Dongliang Yuanwang-3 of the China Satellite maritime monitoring and control department is on a mission in the ocean. Photo by zhangqingchi The vast ocean is cloudless. "Changjiang 3, find the target!" The order was broadcast all over Yuanwang 3. At this moment, the machinery in the engine room is roaring. Below the waterline, you can see all kinds of equipment and pipelines. In the eyes of engineer liutianshui, there seems to be a flash of light, just like the trajectory of a rocket cutting through the sky thousands of miles away. "Coming!" In the central control room, liutianshui observed the fluctuation of the power meter pointer. As time went by, when the pointer returned to stability, liutianshui was still nervous - the hidden risk of the task was not over. "Yes!" It was not until the news of the success of the mission came that Yuanwang 3 escorted the Shenzhou 14 manned spacecraft into orbit accurately that liutianshui was relieved and embraced the other crew members. This is the 100th time that Yuanwang 3 has carried out marine measurement and control tasks, and also the 100th victory that Yuanwang 3 has welcomed. Return is still a teenager When the joy of victory faded, Yuanwang 3 recovered its tranquility. The 28 year old ship is still completely white, and the corridor cabin is spotless. As soon as the engine room door was opened, a billowing heat wave came to my face and a strong noise filled my ears. The author followed Liu Tianshui along the daily route and found that this "iron forest" was surprisingly clean. "In the cabin, rags can be seen everywhere. They are all prepared for the equipment." Liutianshui sometimes picked up the listening stick, resisted the equipment and listened carefully to the sound, sometimes bent down to pick up the dishcloth and rubbed the nearby oil stains back and forth. "Your home should be clean." The engineer, nearly 50 years old, raised his cuffs at random, wiped the sweat off his forehead and continued his inspection. In the cabin of Yuanwang 3, any tiny oil stain will be cleaned immediately. Sometimes, the crew members are afraid of soiling the floor after repairing the equipment, and even take off their shoes and walk back to the cabin barefoot... These details contain the secret that Yuanwang 3 can remain "young" after 28 years of intensive work. It is normal for the hull to be clean and tidy, and it is also normal for the crew in the engine room to be covered with oil. That year, liutianshui and his colleagues went down to the bottom of the ship to clean up the bottom hold. When the iron plate was lifted, the cabin bottom was dark, various pipelines were interspersed, and the strong stench was mixed with the smell of engine oil, which made people sick. Liutianshui took the lead to go down to the bottom cabin, and the greasy mixture didn't cross his legs in an instant. …… The clean-up work lasted more than half a month. About 10 marine engineers cleaned out the garbage bit by bit, and the bottom of the bilge was finally seen. Around the machinery all year round, they are covered with oil and sweat, and the engineers always smell a little. "The oil is hard to wash!" In those days, Liu Tianshui always rubbed the washing powder twice and then washed it twice with shower gel. "I always feel fresh without washing. However, seeing that our boat is getting whiter and whiter, I feel very fresh." He said. Thirty years ago, Liu Tianshui, in his hometown in Dezhou, Shandong Province, built roads, set up stalls and sold fried dough sticks. "He can only sell 2 yuan for picking up beer bottles at noon.". He never dreamed that when he was 18 years old, he would make friends with a large ship called Yuanwang, and he never dreamed that he could sail with the ship to the "sea of stars" of China Aerospace again and again. Now, looking back, it seems that everything is doomed. "Liu Tianshui, is to stay in the place of Tianhe water!" Lao Liu hehe smiled. As one of the first crew members, liutianshui watched Yuanwang No. 3 "sail" out of the drawing. At the beginning, he never dreamed that he would accompany the ship for 28 years, and even more unexpectedly, he could achieve "100 wins" with the ship. "Nothing makes me happier than a smooth mission." In the past 28 years, like a treasure chest, liutianshui has churned out urgently needed parts one after another in the ocean. In his eyes, the ship is always in the same state and young as him. "As long as I need it on the ship, I will always work.". "I can't say how different each task is, but I remember it." Liutianshui is fond of collecting stamps. Since he came to China's satellite marine monitoring and control department in 1992, he has started collecting envelopes, stamps and commemorative coins with aerospace themes. Gradually, his space themed collection was collected into more than 100 books, which were stacked almost one person high. "It takes a long time to go to sea. Sometimes I get tired of it. I'll feel at ease when I look through the mail books." In 28 years, during the long voyage of the Pacific Ocean, the Indian Ocean, the Atlantic Ocean... Enough to circle the earth 35 times, Liu Tianshui returned to his room from the deep cabin on countless ocean nights, and looked through these mailing lists again and again with rough hands. The smell of engine oil that could not be washed off his body was also stained on the mail album. Touching the familiar collection, liutianshui, who was not good at words, became talkative—— "Look, this envelope is the Autographed name of the leaders present when the No. 3 ship was launched..." "So far, we have carried out 12 Shenzhou missions out of 14. Although I have commemorative stamps for Shenzhou 11 and Shenzhou 12 missions, it's a pity that we didn't go on those two missions..." "Sometimes, I feel like I am in the stamps. The stamps tell my story, Shenzhou, Beidou, Chang'e, Tiangong, Fengyun..." Looking at the spectacular scene of various types of rockets taking off on the stamps, Liu Tianshui felt that his vision was very broad: "I have witnessed the Yuanwang 3 becoming a 'famous Chinese ship', China's' Yuanwang 'advancing into the ocean and the vigorous development of the aerospace industry of his ancestors." Since it was put into operation in 1995, Yuanwang 3 has completed 17 missions in its first 10 years; In the second 10 years, 43 missions were completed; In the last 8 years, the number of tasks has reached 40. Once the root is planted, time flies. Liutianshui remembers that in 1993, he picked up the ship at Jiangnan Shipyard. At that time, Yuanwang 3 was just a steel plate, lying flat in the open dock. The jingling sound of the hammer still seems to be ringing in his ears. Yuanwang 3 crossed the sea in 2001 when carrying out the Shenzhou II TT & C mission. He made a telephone appointment with his fiancee to get married when he went back, telling her to clean up the old house and book a hotel first He became a father during the Shenzhou V survey and control mission in 2003. At that time, the photos could not be transmitted to the sea, so it was difficult to call home. When the task was over and he came home, his son was full moon. The last overhaul of Yuanwang 3 was in 2017. On the day of undocking, the sun was shining brightly. Yuanwang No. 3 took on a new look and sailed into the river and sea again. He sighed: "return is still a teenager, I and the boat are..." The thick album also left many blank pages waiting for liutianshui and his ship to fill up with the next track. Acceleration in the new era Liutianshui just got off work when he met the dispatcher in the corridor. The 27 year old young sailor has worked as a dispatcher for two years. "If I sit at the dispatcher's desk, I will not be me. I represent the Yangtze River No. 3." Sitting in the dispatching hall for the first time, Gao Gao was excited and nervous. Turn on the dispatching radio and listen to the password of Beijing direction. The voice he answered was simply loud: "Changjiang 3, normal listening! How do you like my voice?" The dispatcher hesitated for a while, and then came the feedback: "Changjiang 3, I hear your voice is a little loud... Pay attention to adjustment." There was a burst of relaxed laughter in the originally serious and tense dispatching hall. After several major tasks, the shy young man in Dalian became more calm and crisp, as if he had changed his personality. "320 do you understand?" "Yes..." during a drill, the leader of a system gave a wrong answer when scheduling. At the review meeting, Gaochao changed his usual mild attitude and seriously pointed out: "the task should not be lost, and the operation password should not be wrong." In 2020, superb ushers in a special test. "Emergency measurement and control! Emergency measurement and control! Changjiang 3 will start preparing immediately." Two hours before the start of a certain type of task, the superior suddenly issued a notice: due to the sudden failure of a radar of a measurement and control station, some tasks in the charge of the station were temporarily assigned to Yuanwang 3 ship. How to allocate power, organize and dispatch, and ensure smoothness? The changes came suddenly, and the tasks increased abruptly. For a while, thousands of things rushed to the top of my mind. Although it is a temporary test, Gaogao is familiar with the task scheme and process operation. In the last drill assessment, he used only half of the specified time to accurately issue a full set of dispatching instructions. After a short study and communication, Gaochao quickly clarified the task and prepared for it. According to the post characteristics of each professional group, he methodically issued the command: "301, adjust the course; 330, organize calibration..." In the sound of dispatching, the participants divided into two routes, ran away from their seats, rushed into the conference room, received task documents, studied and formulated plans, and confirmed the technical status A few hours later, "the target is out of the horizon!" "Changjiang 3, find the target!" The dispatching and command were orderly and the task was successfully completed. 10 minutes for emergency, 10 years behind the scenes. The story of the young crew member reflects the growth track of the crew member Yuanwang 3 from generation to generation. How fast is a sharp sword made in 28 years? Under the tests of new tasks, new sea areas and new technologies, Yuanwang 3 is constantly meeting new challenges and maintaining its best state at all times. Haoyongai, a 32 year old radar operator, competed with him. In his spare time, he often practiced "left-hand and right-hand fighting" like the great Xia in the martial arts novels, drawing a square with his left hand and a circle with his right hand. Why should we practice this multi-purpose skill? Because his job "target capture" requires a reasonable distribution of attention. Although he is young, this task is the 45th task he has completed. Kangqi, a new student in the marine engineering system, drills the engine room with a picture album every day. Open the iron plate, he went down to the bottom of the cabin and lay down on the pipe to draw the direction of the pipe. After a month, the young man lost about 10 kilograms and drew 10 kilograms of paper, which depicted the internal organs and tendons of the cabin in his mind Last year, the qualification rate of Yuanwang 3 reached 100%. For countless days and nights, the lights in the ship's test engine room were bright, the talent matrix was tempered in an all-round way, and a large number of backbones became "understanding people" and "pillars" of various disciplines. "The acceleration of the new era gives us a strong sense of pushing back." On a quiet noon, Gao Gao was buried in the middle of two thick stacks of data files, browsing the task chronology from the computer screen. He held his glasses, created a new line, and solemnly knocked down: "No.: 100, task: Shenzhou 14." This stage is big enough With the roar, the UAV was close and far away, circling around Yuanwang 3 along the set track. "UAV is a controllable moving target, which helps us complete radar calibration efficiently." Huangguoxiong, a senior engineer, took down the UAV from the block and returned to the computer room. At this moment, the data analysis has been completed, and the radar begins to calibrate independently. In the past, survey ships were calibrated by calibration towers or balloons. The former is fixed on the shore and is not suitable for sailing; The latter is to carry a beacon in a helium filled balloon and put it into high altitude for signal simulation. "Each calibration consumes a beacon ball, and tens of thousands of yuan is gone. It hurts." The high cost, complicated procedures and low efficiency of offshore calibration have always troubled senior engineer Huang. The golden idea of calibration using UAVs is rooted in a fertile land of innovation. As early as the beginning of the construction of the ship, the Party committee of Yuanwang 3 put forward the slogan of "innovation + task", aimed at the goal of "innovation ship", cultivated multiple innovation teams, explored and built an innovation reward mechanism, and promoted the development of the ship
