People who have "physical examination" for missiles ■ likunfeng, yangjieyu, jiangzihan Many years later, Qin Liang still clearly remembers his first visit to a missile laboratory at Naval Aeronautical University. "Did you know that missiles also need health management?" This is the first sentence Qin Liang heard when he reported to the laboratory. "Physical examination" for missiles is the main research direction of the laboratory. When we first arrived at the missile laboratory test center, we saw rows of testing equipment. During the shuttle, the scientific researchers imported the missile status data collected from the army into the analysis software, and a "health management form" was generated... Qin Liang was shocked and excited by this scene. Under the leadership of Professor shixianjun, who has been engaged in missile test technology research for many years, Qin Liang saw the prototype of the three generations of general test system. Pointing to the device, shixianjun told the story behind the device. It was the struggle of countless teams day and night, with the joy of success and the loneliness of failure. "Every setback is a progress, and the more failures, the closer success." Shixianjun said. At the beginning of the establishment of the laboratory, domestic missile testing was still in its infancy. "Lacking reference materials, we can only feel the stones to cross the river." Faced with different types of missile test signals, shixianjun and his team tried to solve the problem of universal test by looking for the internal relationship of signals through simulation modeling. Research site of a missile laboratory. Photographed by liuzeshuai In the day-to-day research and exploration, the imagination has become a reality step by step. In 2001, the first generation of general test system was successfully developed, with full coverage of detection capability, realizing a breakthrough in missile general test technology from zero to one. This technology won the first prize of the military science and technology progress award. What pleased shixianjun most was that he received many calls from grass-roots units. They have reported that "it is easy to use and effective, and the work efficiency has been greatly improved". Walking around the laboratory, a thick notebook is particularly eye-catching - it is full of telephone numbers. This notebook is the "baby" of laboratory researchers, recording the contact information of various troops. Researchers would regularly call all units to learn about the use of missiles. Over time, the book was turned to the side. "Military scientific researchers should not study behind closed doors. They should set up a test-bed on the front battlefield." This is the true feeling of zhoushaolei, a professor in the laboratory. Focusing on missile support research for more than 30 years, he and his team have been like a group of migrating birds. They "fly" to where they are equipped with support needs. "On the summer coast, the outfield temperature was close to 40 ℃, we were busy at the test site against the sun for more than a month, and we never went home..." Zhou shaolei was very impressed with that support experience. At that time, a new type of equipment was "acclimatized" after being installed in the army, and failures occurred frequently. After receiving the call for help, they went to the emergency maintenance. For each signal and component, they combed and analyzed them over and over again, disassembled and tested them one by one, and did not miss any hidden trouble. Through the joint efforts of all, the problem was solved. When he saw the missile's tail flame shining in the sky, zhoushaolei was so excited that tears filled his eyes. He patted the soldiers on the shoulder and said, "I can safely give it to you this time." Such a "tall and high" career needs "grounding gas" most. This is Qin Liang's deepest feeling in the laboratory for many years. Running between the laboratory and the training ground, his skin became darker and his voice became louder. In the laboratory, Qin Liang, who has just been rated as an associate professor, is leading a dozen master's and undergraduate students to conduct analysis and research around a missile. The original newcomer is now in charge of his own affairs. Now he has undertaken research on a number of key topics, completed the development of multiple sets of equipment, and won a number of science and technology and teaching awards and invention patents. Qin Liang has been committed to promoting the "second class" of students. "The interaction between scientific research and teaching feedback is our unremitting goal." Qin Liang said. After years of hard work and development, the research field of the laboratory has covered all aspects of missile equipment technology. Whether it is the early technical preparation or the follow-up demonstration review, whether it is the development site of the industrial department or the launch site of the training exercise, we can always see the presence of the experts and professors in the laboratory. They have become an important bridge between equipment development and battlefield use. (outlook new era)
