I am a rivet, tiny but deeply embedded in the steel chest, holding up every soaring eagle... "At the beginning of this year, three aviation repair soldiers recited a poem created by mechanical technician and first grade sergeant Jia Shijia on a stage of a cultural performance in a certain brigade of the Army Aviation Academy -" I am at ease sailing under the wings. Word by word, with a resounding sound, Jia Shijia sitting in the audience couldn't help but blush. In his mind, the images of his comrades climbing up and down around the fighter jet came to mind one after another. Rooted in the ground and looking up at the sky, although Jia Shijia has never flown high with a fighter jet, he and his comrades are full of enthusiasm for the aviation repair industry. At the end of the program, the comrades on stage shouted out their hearts together: "Love fighter jets like life, lift up hope for takeoff. With me under your wings, please rest assured to set sail!" "I would rather work hard ten thousand times than let my comrades take risks" "To be a good aviation repairman, starting from learning how to count tools. ”This is the first thing that every new recruit is told by the mechanical technician and third level sergeant in the army when they arrive at the aviation repair company. Going back 20 years, the army remembers that it was his first support mission as a mechanic. After completing the maintenance work, he suddenly found that a thumb sized sleeve was missing. Oh no! ”The army felt a tingling sensation and quickly searched with their comrades for the missing parts. A whole day passed before everyone found the sleeve in the gap of the helicopter engine. Any small operation is related to the safety of the war eagle. ”That experience sharpened the Army's impetuous nature and taught him the art of "details win" in aviation maintenance: "It's better to work hard ten thousand times than to let comrades take risks." Hard work pays off. Three years later, the army became the earliest mechanical technician among the same batch of soldiers to complete the "release of orders" assessment. He can accurately detect subtle deviations in pipeline interfaces and hear abnormal sounds during engine operation. That day, the army and his comrades conducted regular inspections on a helicopter, and the strange noise inside the tail reducer caught his attention. He leaned his ear close to the fuselage, repeatedly turning the tail rotor blades, and the faint "rustling" sound remained. The army immediately applied to the higher authorities for disassembly inspection. Removing the outer cover, inspecting the tooth surface, and positioning the probe... Indeed, the fixing nut of the internal bearing has become loose. Da, da, da... "As the army rhythmically turned the wrench in an orderly manner, the malfunction was successfully resolved. We must never allow fighter jets to take off with hidden dangers. ”The army said that this is not a grandiose statement, but the true voice of aviation repair officers and soldiers. Sergeant Wang Jiacheng also felt a lot about this sentence. As an avionics officer, he needs to ensure that tens of thousands of electronic components in the helicopter are connected properly and operate smoothly. In a recent competition, Wang Jiacheng won first place in the electronic soldering project: "Circuit board soldering is a skill on the tip of a needle, and even a 0.1 millimeter error can affect the 'meridians' of a helicopter, causing fatal danger." In order to practice stable, accurate, and ruthless soldering skills, Wang Jiacheng "soldered" himself in the workshop every day during his break time, repeatedly practicing on components the size of rice grains on the circuit board. Fingers were scalded with a soldering iron, causing blisters. Apply a band aid and continue with the operation. Repeating tens of thousands of times is just to make the welding points smoother and more secure, so that the fighter can safely take off. Sergeant Major Cheng Xiaojiang is a flight analysis technician. He often said that as an aviation repairman who "checks the pulse" of helicopters, the word "almost" has never been in the dictionary. The flight data of a helicopter is extremely complex, and any parameter may contain hidden faults. When interpreting, one must be meticulous and cautious. ”Cheng Xiaojiang said that before each flight is launched, they need to conduct repeated inspections. Engaging in aviation repair work requires extreme responsibility to capture extremely subtle anomalies from thousands of data curves. That year, Cheng Xiaojiang discovered an abnormal signal in the engine bleed valve of a helicopter. He suddenly felt a tightness in his heart and quickly conducted a survey of all helicopters of the aircraft model, discovering that there were also fighter jets with similar problems. If the air release valve suddenly strikes when the helicopter is urgently avoiding obstacles, it may cause the flight power to not keep up, resulting in a tragedy of aircraft destruction and loss of life. ”Realizing the seriousness of the problem, Cheng Xiaojiang immediately reported the situation and proposed the suggestion of grounding and returning to the factory for decomposition and testing. Some comrades believed that he was overthinking: "No problems were found in the external inspection, and the abnormal parameters may be related to the recent training environment, which is a normal phenomenon." However, Cheng Xiaojiang insisted on his own judgment: "From historical data, under the same flight course and meteorological conditions, the deflation valve signal is normal. Why did the abnormality occur this time?" After comprehensive consideration, the military leaders canceled the flight mission of the problematic helicopter and returned the components for factory testing. Shortly thereafter, the military received feedback from the manufacturer that the malfunction was caused by a rupture in the internal welding joint. After troubleshooting this issue, the helicopter was successfully launched. If we delay for one second, the deployment of the fighter jet may be delayed by one step, "Gao Gongwei Xinliang received an emergency maintenance task. He fired a bullet from his seat, hastily bid farewell, and quickly headed to the hangar, leaving behind a running figure. Accelerating and running is the norm for this group of aviation repair officers and soldiers. Wei Xinliang said that in recent years, the intensity of practical training has been increasing, and the deployment rate of brigade helicopters has repeatedly reached new highs. Aviation equipment maintenance is also facing new challenges. That year, a helicopter suffered fuselage damage after carrying out a difficult course training mission and was unable to take off again. Looking at the damaged area, Wei Xinliang fell into deep thought: "If we contact the manufacturer to repair it, it will take a long time to tinker around, and the training progress will be affected. If there is no one on the battlefield, how can the enemy give us time to wait for technicians to come and repair?" That night, Wei Xinliang couldn't sleep all night: "We must take the initiative to attack and overcome the repair problem." The next day, Wei Xinliang volunteered to form a research team with other comrades, determined to tackle this hard bone. After opening the helicopter roof, they realized a series of practical problems in front of them: in addition to repairing the damaged surface of the fuselage, the internal fractured parts also needed to be repaired, which was much more difficult than they expected. Although the rivet is light, it connects to the frontline battlefield; Although nuts are small, they are crucial for winning battles. ”Wei Xinliang said, 'If we delay for one second, the fighter jets may be delayed.' Afterwards, the studio added a few more lights at night, and brainstorming sessions quickly unfolded one after another. There is no ready-made technical solution, so they work overtime to search for information, deduce technical indicators from the guarantee requirements, and scroll through dozens of professional manuals; Without mature process standards, they simulate various environments and repeatedly test the performance of repair materials. The members of the research and development team are responsible for the daily maintenance of the helicopter during the day, and can only use their rest time at night to overcome difficulties. In order to find the repair method as soon as possible, in the late night inspection hangar, Wei Xinliang and his comrades crouched down and repeatedly adjusted the material ratio, polishing and repairing the coating. After repeated research and development, the maintenance method that everyone started from scratch has finally passed the inspection of a professional department. Afterwards, they carried out multiple rounds of improvement and successfully applied the repair technology to the maintenance of various types of aviation equipment components. It is gratifying that the achievements of independent innovation by aviation repair officers and soldiers have helped helicopters to move faster and their ability to win has been steadily increasing. Above the helicopter nose, a soldier is maintaining and repairing a generator, and the carrier holding it is actually a homemade invention that weighs less than a quarter of its own weight. Engineer Wang Jiong is the designer of this invention. He said that in the past, everyone needed to work together to move the dismantled generator to the ground for maintenance, which was not only time-consuming and laborious, but also prone to damage parts. Now, with this multifunctional workbench, the dismantled generator can be directly placed on the device for maintenance, and one person can complete the entire operation process, greatly reducing the maintenance and repair time. To safeguard flight safety and prevent abilities from being stuck by 'fences', "Kong He, a second level sergeant, opened the electronic record of his training. He had rich and diverse experiences of studying abroad, such as" going to the manufacturer to master a certain advanced welding technology "and" going to colleges to learn about oil monitoring methods ". Over the years, his educational journey has spread throughout most of China, and every time he sets off, he moves towards the goal of being versatile and specialized. The pursuit of "multi energy" stems from an urgent laboratory task. Due to a shortage of personnel for oil analysis, Kong He was temporarily called to the oil analysis room to assist with the work. At that time, I only knew some simple operations and struggled for most of the day before barely completing the task under the guidance of my comrades, "he said. Guarding flight safety, abilities cannot be blocked by 'fences'. ”This incident deeply touched Kong He. In recent years, with the increasing frequency of the installation of new fighter jets, everyone's work has become busier and busier. "Only by strengthening the 'eighteen martial arts' can we remain calm and capable in the face of tasks." "One specialization and multiple abilities are not only the' addition 'of skills, but also the' multiplication 'of battlefield positioning and efficiency enhancement. ”With this clarity of mind, Kong He embarked on a path of interdisciplinary learning. That year, the brigade was equipped with a new type of fighter jet. Faced with unfamiliar process standards and technical parameters, he actively applied to participate in the special training organized by the manufacturer, and never left to learn new technologies in various majors from engineers. Over the course of three months, Kong He learned and practiced while summarizing the "three-step maintenance method", which played an important role in the rapid formation of combat effectiveness for this type of fighter jet. Captain Kong is a true 'hexagonal warrior', proficient in various professional skills such as metrology, process preparation, oil analysis, and flight reference interpretation. ”Nowadays, Kong He is seen by his comrades as the vanguard of support, capable of standing up wherever needed. In the summer of that year, the team organized a helicopter emergency landing in the wilderness for repair drills. Upon receiving instructions, Kong He immediately led the team with spare parts to rush to the rescue. After arriving at the scene, he found that some of the temporary replacement team members were not proficient enough in operating non professional skills and frequently got stuck, resulting in slow repair progress. This experience made Kong He realize that "battlefield support relies on teamwork, and individual 'multi ability' is far from enough." In order to achieve the transformation from 'individual multi ability' to 'team strong ability', Kong He led his comrades to learn and master knowledge such as oil analysis and flight parameter interpretation, explore and repair new technologies and methods, and constantly make up for their own shortcomings in abilities. Under the influence of Kong He, more and more aviation repair officers and soldiers are embarking on the path of cross disciplinary growth and success. Over the years, he has taught more than 100 apprentices, the vast majority of whom are proficient in two or more professional skills, becoming the backbone of the brigade's aviation maintenance support.
