Soldier's ingenuity Watching the eagle fight in the sky, staring at the armor galloping on the battlefield, and following the cavalry for thousands of miles... There is such a group of soldiers who may never appear at the front of the battlefield, but study hard with the heart of craftsmen and ensure victory with the heart of victory. In this issue of soldiers' faces, we approached four soldiers "craftsmen" in equipment maintenance positions, felt their persistence and focus, and witnessed their research and perseverance. —— editor Proud moment ■ Liu Hanbao, Xu Bohan [name card] Dou Shujun, first class Sergeant chief of a brigade of the air force aviation force in the northern theater. He has been rated as a model soldier of loving the army and becoming an advanced individual in the country, won the first prize of the excellent non commissioned officer award of the whole army twice, enjoyed the special allowance of the government of the State Council, was awarded the honorary title of "post loving and professional model non commissioned officer" by the air force, and was awarded the first-class merit once, the second-class merit three times and the third-class merit six times. After several days of heavy snow, an airfield of the air force aviation corps in the northern theater was covered with snow, and the temperature exceeded minus 20 degrees Celsius. With the deafening roar, a fighter plane accelerated along the runway, skimmed lightly over the horizon and plunged into the sky like lightning. In the hangar not far from the runway, the maintenance officers and soldiers were busy repairing the fighters. The big red characters on the outer wall of the hangar - "be a soldier like Dou Shujun" stand out against the snow. Who is Dou Shujun? What kind of soldier is he? He is a "soldier expert" in the field of nondestructive testing of the air force. He is a "fighter miracle doctor" who is not allowed to bring faults into flight and has worked for 30 years without errors. With the help of his comrades in arms, Dou Shujun climbed out of the air inlet of the fighter with a diameter of less than 60 cm. The air inlet space is narrow, allowing only one person to crawl. It is like a stove in summer and an ice cellar in winter. Dou Shujun has been dealing with the air inlet for 30 years in the posture of crawling and lying, holding a flaw detector weighing more than 5kg. On a cold day, Dou Shujun was dressed in a thin ground work clothes, and his thin cheeks were blue and white. Putting on the military coat handed over by his comrades in arms and a cup of hot ginger tea, his face gradually ruddy. Dou Shujun, who is not tall and usually has few words, is not prominent among a group of maintenance soldiers, but the rank of first-class Sergeant makes people have to pay attention to him. The engine is like the heart of a fighter, and Dou Shujun is responsible for flaw detection of engine blades. The engine made of steel looks indestructible, but the blade is easily to produce small cracks invisible to the naked eye due to various factors. These cracks will cause the blade to break at high speed, which will bring fatal hidden dangers to flight safety. In order to avoid this hidden danger, the flaw detector needs to take preventive measures through a series of professional detection means. Over the years, Dou Shujun has inspected more than 9000 sorties for 10 types of aircraft and more than 850000 blades of various types. He explored and summarized the three-step positioning flaw detection method, which greatly improved the flaw detection accuracy. A few years ago, several local airlines targeted Dou Shujun, who was famous in the industry, and all sent invitations with generous treatment. Almost without any hesitation, Dou Shujun firmly chose to stay in the army and continue to "feel the pulse" for the War Eagle. In 2020, considering that the army had just been equipped with new fighters and had reached the retirement age, he took the initiative to apply for an extension of service. Up to now, he still sticks to his position and carries out flaw detection for the fighters conscientiously. "The wings are hard and fly for the party!" In Dou Shujun's view, the moment when the pilot thumbs up to him before the fighter takes off is the moment when he is most proud. The wind gradually decreased, and the sun shone through the gaps in the clouds to the earth. The whole airport was shrouded in a golden light. "The plane is in good condition. After checking the remaining blades later, you can continue to participate in the training." Dou Jun's coat slipped into the narrow air inlet again. Like every time, he carefully examined every detail and continued to interpret the perseverance and perseverance of the air force maintenance corps with zero errors and omissions. The lights are bright at night ■ Ding Wenhui [name card] Liu Jiaping, first class Sergeant chief of a brigade of Xinjiang Military Region. He has been rated as a national technical expert, a model of the whole army's love for the army, and a model of the army's first revolutionary soldier in the "Four Haves" new era. He has been awarded second-class merit for three times and third-class merit for one time, and enjoys the special allowance of the government of the State Council. Late at night, the door of the family building was closed. With a "squeak" sound, the door was pushed open from the inside, and Liu Jiaping's tall figure appeared under the dim yellow street lamp. He tightened his collar and disappeared into the darkness. The simulation training system of a certain type of command and control equipment, which took five years to develop, is finally about to be accepted. In order to ensure that everything is safe, Liu Jiaping, as the person in charge, will do the final debugging. Through the dark training ground, a two-story office building - "technician's home" in the distance shows a little light. His studio is among them. The thick and hardened sand and gravel ground and the howling cold wind pull Liu Jiaping's thoughts back to many years ago. Before the official relocation of the unit, it was temporarily stationed in a farm on the Gobi desert. Because the room is limited, officers and soldiers can only work and live together, and there is no room for Liu Jiaping's R & D equipment. Liu Jiaping walked around the farm for several times and finally found a slightly spacious place - vegetable cellar. With the consent of his unit, he moved all the equipment in. At that time, Liu Jiaping often worked late into the night. When he was tired, he leaned against the rice bag to have a rest. The light in the vegetable cellar was dim and the ventilation effect was poor, but Liu Jiaping's progress could not be stopped. He won the third prize for the research and development of a military intelligent command system and power supply system for two years. Climb to the second floor of the "technician's home", and Liu Jiaping stops at the door of the third office after turning left. The sign "Liu Jiaping studio" is embedded on the brownish red wooden door. He gazed at this sign countless times, and his heart was filled with more responsibility and mission than moving. A few years ago, with the completion of the new camp, the repair workshop was officially put into use. That day, Liu Jiaping and his comrades in arms excitedly walked into the workshop. When he stepped into an office on the second floor, Liu Jiaping was stunned - a room of more than ten square meters was neatly placed with scientific research equipment and maintenance tools, which was simply his dream office. At this time, Captain Guo Lei solemnly handed a bunch of keys to his palm: "this is the studio prepared for you with special funds." Liu Jiaping clenched the key, excited and delighted... Complex emotions filled his heart. Under the gaze of comrades in arms, "Liu Jiaping studio" was officially established. On many brightly lit nights, the "Liu Jiaping studio" sometimes sounds the crackling sound of taking off and tapping the keyboard, sometimes a wisp of green smoke of soldering iron welding components, and sometimes fierce debates among the team members... These efforts have finally paid off -- over the years, the studio has collected tens of thousands of technical parameters; Maintain more than 1000 sets of main battle equipment; Put forward more than 60 innovation suggestions; Nine innovation achievements won the military science and technology progress award. In 2020, the repair workshop was transformed into a "technician's home", and a group of "makers" like Liu Jiaping applied for settlement. A large number of innovative ideas took root, germinated and grew here. At 3 a.m., Liu Jiaping turned off the lights and walked out of the studio. His appearance was reflected in the military appearance mirror at the door of the building - broad shoulders, tall, slightly hunchbacked, serious eyes shining under the thick lenses, and his black hair had been stained with wind and frost. Liu Jiaping tried to straighten his back in front of the mirror and couldn't help but sigh that time flies - this is his 26th year as a soldier. The moonlight is cold, the Star River is bright, and the "technician's home" is covered with a layer of silver. Looking at the lights in the window, Liu Jiaping was full of comfort and confidence. Armored position ■ Yu yaya [name card] Wang Youwu, second Sergeant chief of an experimental training base of the army. It has been rated as "excellent soldier" for seven times and won the third class merit once. In 2018, it was identified as the first batch of training objects of technical excellence in the army. The time of separation has come again. Two newly repaired guns were solemnly hung with eye-catching red flowers on the barrel, which was a parting gift from Wang Youwu and his comrades in arms to the "old guys". The numbers were erased and the firing parts were removed, and they have completed their combat mission in the shooting range with honor. One day soon, they will officially appear in a national defense education base or military museum to tell visitors about their past glory. Wang Youwu's technical support team manages and maintains more than 40 types of tanks, armored vehicles, artillery and other equipment, with a total of more than 300 sets. The scrapped, retired, in-service and unshaped ones span more than 60 years, which is enough to form a large-scale "exhibition hall". In the quiet of the night, Wang Youwu, as a team leader, has developed the habit of carefully overhauling equipment and updating accounts for many years. The rough Palmprint and the lingering smell of engine oil are the traces left by years of maintenance equipment. Wang Youwu has a clear account of the war technical indicators of each equipment, when to maintain it and when to replace parts. He has special feelings for these equipment. In his opinion, although these equipment can't speak, they also have their own temper: if you are more patient with them, they will naturally treat you better; The deeper you study and understand them, the more confidence they give you. In the eyes of his comrades in arms, monitor Wang is a practical and capable man. After 23 years in the army, he has mastered the driving and maintenance skills of 22 types of tanks and armored vehicles and the operation and use of more than 20 kinds of artillery. He can judge whether tanks and armored vehicles are normal only from the driving track, motor sound and operation of variable speed manipulator. Several leaders spoke highly of him: as long as Lao Wang was there, there would be nothing to worry about in various businesses of tanks and armor. Wang Youwu feels that he is not so divine. He has no systematic learning experience in Colleges and universities. His post is his classroom. He, who has been responsible for the task of assembly for many years, explores while practicing. From the oil circuit, circuit, firing parts to the chassis, he checks and verifies the parts one by one. Often after the equipment acceptance, he has mastered the basic operation and maintenance skills. After dealing with tanks, armored vehicles and artillery for a long time, Wang Youwu has a temper similar to these equipment. Yang Zhichao, as an apprentice, has a deep understanding of this: "if you can't learn all kinds of operation demonstration twice, monitor Wang is anxious." The unit has many types of equipment and intensive tasks. Wang Youwu always gives everything. I hope the disciples can learn their skills as soon as possible. Under the rough appearance of the northwest man, Wang Youwu works very carefully. In a test, the tank responsible for the test task broke down suddenly. After investigation, Wang Youwu found that it was caused by the falling off of fuse and the loosening of oil pipe. After rapid troubleshooting, the same problem occurred again a few days later. Therefore, Wang Youwu tried repeatedly and found that after the tank travels at the speed of 20-30 km / h for a period of time, it will cause resonance of parts in the vehicle and eventually lead to the falling off of the link interface. The unit timely fed back the problems and improvement suggestions to the military factory. In recent years, Wang youwulu has put forward more than 20 similar suggestions for equipment improvement. In snowy plateau and desert Gobi, field test is not only the limit assessment of equipment performance, but also a great challenge to the ability and quality of participating officers and soldiers. There is always Wang you in the army
