Many people are fascinated and yearning for the unrestrained and heroic posture of the pilot. Behind them flying in the clouds, there are a group of maintenance soldiers silently guarding the health of the eagle. Flying and watching are the daily combat posture of the maintenance soldiers. Liao Rongmin, a mechanical technician of a regiment of the air force aviation corps of the Western Theater, and chief sergeant of the third grade, is one of them. On September 4 this year, after several rounds of fierce competition, the crew of the regiment won the champion of the military transport crew of the "international military competition-2021" and "air darts" project at liangzanjia jilevo airport, Russia. Captain Liu Wei took the trophy from the leader of the Russian air and space army, and his heart was full of pride. Walking off the podium, Liu Wei held Liao Rongmin's calloused hands tightly and said emotionally, "your efforts and efforts are a strong guarantee for us to win the championship. We can rest assured to fly the plane you maintain!" For pilots, maintenance is the trust of life and victory. The affirmation of the pilot is the greatest praise to the maintenance soldiers. In recent years, as a maintenance veteran, Liao Rongmin has witnessed the rapid development of China's air transport delivery force and aviation maintenance industry—— Maintenance of aircraft, from old models to advanced domestic medium-sized transport aircraft; Flight path, from inland hinterland to plateau and ocean, from domestic to overseas; Tasks performed, from joint exercises and training to international military competition, from rescue and disaster relief to anti epidemic rescue "I'm a maintenance man. The more I work, the more energetic I am!" Liao Rongmin said. Lift up the fighter and be the hero behind the scenes. Liao Rongmin's personal experience is an annotation that the people's air force of the new era has stepped into the threshold of the strategic air force and accelerated its flight to the goal of building a world-class air force in an all-round way. It is also an epitome of the growth and transformation of the noncommissioned officer talent team in the new era. Liao Rongmin, mechanical technician and third Sergeant chief of an aviation regiment of the air force in the Western Theater—— The hero behind the lift off ■ Guo Jin, special reporter of PLA Daily, Yang Jin Maintenance officers and men enter the site to make advance maintenance preparations. Ouyang LingChao "Aircraft is alive. You can understand its words only when you pay more efforts and sweat." "When your starting point is lower than others and you want to fly higher, you have to keep flapping your wings in order to ensure enough lift." Liao Rongmin concluded by reviewing his 17 years of military career. "When I was a child, I was very excited to see the plane across the sky in the field. I didn't expect that one day I could guard the eagle flying in the sky." Liao Rongmin was born in a small village in southern Hunan by the Xiaoshui river. His first impression of the plane came from looking up at the blue sky when he was a child. In 2004, Liao Rongmin joined the army and became a glorious mechanic. The old squad leader said to him, "the maintenance soldier is the 'doctor' of the aircraft, and our duty is to protect its health." Standing in front of the mighty fighter, his heart was excited. On that day, he touched his own future space - blue sky, and found his own dream color - blue sky. However, it is undoubtedly a great challenge for Liao Rongmin, who is not highly educated, to become an excellent mechanic. Every time he looked through professional books and looked at complex structural diagrams, formulas and data, he would be a little scared. So he wrote four words on the title page of his business learning Notebook: "study hard and practice hard". Behind the word "hardship" is the determination to overcome difficulties. For more than a month, Liao Rongmin wrote down two notes, each of which was rolled. He firmly remembered the parameters of hundreds of core parts of the aircraft. After passing the assessment, he was released to work as a mechanic in advance. "Hard work and tenacity are the weapons for the growth of maintenance soldiers." this assiduous learning spirit has been maintained by him until today. Dozens of business learning notes marked with various symbols have become the most intuitive and effective learning materials for novices in the regiment. With a little accumulation and understanding, he gradually developed a unique skill - to accurately judge the cause of aircraft failure from the details of engine sound and oil leakage. "There is not only knowledge support, but also practical perception. The most important thing is to study hard," Liao Rongmin said. "Aircraft are alive. You can understand its words only when you pay more efforts and sweat." Liao Rongmin has spent much more time with the aircraft than his family over the years. In 2006, Liao Rongmin and his comrades in arms were ordered to participate in an important flight support mission. Before the flight, Liao Rongmin found that there was oil leakage from the vacuum valve of a system during routine inspection. Liao Rongmin determined that the root cause of the problem was the stuck vacuum valve. However, to repair the valve, the entire component needs to be removed. Seeing the aircraft take-off time approaching, the crew were extremely anxious. If it is disassembled, repaired and then installed, it will take at least more than an hour, which is bound to affect the progress of the whole task. "Suck with your mouth!" Liao Rongmin found a hose, took a sip of the hose and blew out a breath. He repeated it more than 10 times and successfully eliminated the sticking fault of the vacuum valve. Such a move moved the pilot on one side. He quickly brought his own kettle and asked Liao Rongmin to gargle. At that moment, Liao Rongmin felt that the value of the crew was affirmed. Although they can't fly in the blue sky, their every move is closely related to the cause of flying. "No matter what your status, you should strive to create extraordinary in ordinary posts," Liao Rongmin said. The main wheel of a certain type of transport aircraft exceeds Liao Rongmin's weight. To disassemble it smoothly, it requires very high physical strength and skills. One winter, the regiment organized post training. On the eve of the event, Liao Rongmin braved the severe cold, wind and snow, practiced disassembling and assembling the main wheel more than 100 times outdoors, pushed and rolled the wheel for more than 100 meters, and his palms were worn out. During the competition, a series of movements, such as removing nuts, taking parts and rolling wheels, were dexterous and skillful, which won bursts of applause at the scene. In 2016, Liao Rongmin successfully won the first place in the project of disassembling and assembling wheels in the mass post training competition of "top maintenance soldiers" organized by the air force. When his comrades in arms asked him about his secret collection of winning the championship, he smiled and said, "no matter whether life is good or bad, every day's efforts count. For this day, I am always ready to work immediately when the opportunity comes." Liao Rongmin's work photo "The credo of the maintenance crew should not stop at responsibility, but should be extremely responsible. Behind the word 'extreme' is responsibility, but also the love of all body and mind." One spring, Liao Rongmin followed his troops to a military factory to pick up and install a domestic transport aircraft. Careful Liao Rongmin found that a part of the aircraft needs to be disassembled and disassembled repeatedly during daily maintenance, which is very inconvenient to operate. After careful study, he suggested that the support and maintenance experience of a certain type of aircraft previously maintained be "grafted" to this type of aircraft. "According to the original design, we can also complete the task, but every minute counts. If we consider the maintenance support efficiency with practical thinking, we need to think and work hard on every detail," Liao Rongmin said. When you are sincere, gold and stone are open. At first, Liao Rongmin's plan did not receive enough attention. However, at his insistence, the reasonable proposal was finally supported by the factory leaders and technical experts - the design of relevant components of this type of transport aircraft is the improvement scheme of Liao Rongmin. Liao Rongmin's phone book records the phone numbers of many manufacturers and college experts. If you have any questions, call for advice immediately; If you don't understand the principle, you have to figure it out no matter how long it takes. "The credo of the maintenance crew should not stop at being responsible, but should be extremely responsible. Behind the word 'extreme' is responsibility, but also the love of all body and mind." in the maintenance post, Liao Rongmin often thinks: why do you do this, and is there a better way to improve it? Over the years, Liao Rongmin's pace of innovation has never stopped. He integrates his knowledge with practice and constantly innovates and improves maintenance means. "In fact, the idea at the beginning was very simple, that is, to make the maintenance support work faster and more standardized." when it comes to his "small inventions and small creations", Liao Rongmin believes that as long as you use your brain to think about problems and make efforts, you will eventually get results. During an outfield support task, Liao Rongmin found that the oil filler was too small to grasp the amount of oil and the refueling efficiency was also very low. Seeing that the water cup he carried with him was marked with a scale, he had an idea. He removed a faucet from a waste water dispenser, tied it with a ball point pen, and aligned the faucet with the narrow filler. Fill the water cup with hydraulic oil, open the faucet valve, and the hydraulic oil will flow in automatically. In this way, there is no need to dump with a long nozzle oil pot, which not only improves the refueling efficiency, but also can observe whether the refueling volume meets the standard at any time. Small innovation, large use, this bold innovation has been recognized by the superior. Soon after, Liao Rongmin's improved achievements were popularized and applied throughout the regiment. Since then, he has taken another step forward on the road of innovation. The outbreak of novel coronavirus pneumonia occurred early last year. Seeing the newly added infrared temperature gun in the regiment, an inspiration flashed in Liao Rongmin's mind: "when a person is ill, his temperature will change, and there will certainly be changes when the aircraft breaks down. Can you also measure the 'temperature' of the fighter?" Teachers from colleges and universities were invited to explain the principle of body temperature gun, search equipment data online, and demonstrate the feasibility in combination with maintenance experience... More than a month later, a set of application scheme of infrared thermal imaging technology for Fighter maintenance was born, which was applied in aircraft anti ice heating, oil and electrical system inspection. Bearing maintenance device, hub fairing loading and unloading device, touch screen fluid constant pressure control system... Now, Liao Rongmin has obtained six national patents, and these innovative achievements have been widely used in the practice of locomotive maintenance support. A few years ago, Liao Rongmin found that there were defects in the refueling and replacement of an aircraft. He carefully studied the advanced experience of foreign military aviation maintenance support, summarized and thought about the current maintenance support work, designed improved equipment, and effectively improved work efficiency. "The windshield wiper of this type of aircraft works for a long time and may fail. This problem can be avoided by adjusting the installation position..." Liao Rongmin found that there are design defects in the windshield wiper of a certain type of aircraft, immediately called the manufacturer and put forward improvement suggestions. A few months later, Liao Rongmin was invited to attend the quality review meeting organized by the manufacturer. At the meeting, he reported according to the first-hand information and detailed data accumulated in his work, which was unanimously recognized by the participating experts. Finally, the manufacturer optimized and improved according to the scheme he put forward. There are many "micro innovations" like this. In the past, Liao Rongmin put forward improvement suggestions to the manufacturer after finding problems. Now, before designing products, manufacturers take the initiative to call Liao Rongmin for advice. The leader of an aircraft manufacturer heard that he put forward a series of optimization design suggestions during the assembly process, and took the initiative to call the regiment and ask for work for him. "The maintenance work seems ordinary, but in the journey of strengthening the army in pursuit of dreams, small people also have great achievements!" said Hu Yuqian, deputy head of the regiment. In August this year, as a maintenance support personnel, Liao Rongmin and his comrades in arms set foot on the field of "international military competition-2021" and "aviation darts". In order to stand out in the international arena, it is a great test for the ability and quality of maintenance support personnel. Liao Rongmin worked with his comrades in arms to carefully analyze the data and videos
