Fly to the blue sky —— Chen Liu, deputy stationmaster of a pilot training base of the air force ■ Tang Jun, PLA Daily reporter Li Jianwen [biography] Chen Liu, male, deputy stationmaster of a pilot training base of the air force, first-class pilot. He was commended as an excellent officer of the "Four Haves" by the air force and was awarded second-class merit once and third-class merit four times. Ultra low altitude penetration and high angle of attack evasion... In the early summer, in the air combat simulation training room of a pilot training base of the air force, Chen Liuzheng, deputy stationmaster and pilot of a unit of the base, and his comrades in arms carried out flight simulation training under extreme conditions. After several sorties, a set of multi Aircraft Cooperative tactics is ready to come out. This set of simulation training system was developed by Chen Liu. It took three years before and after. Now it has been gradually popularized and applied in the air force. "Being the best pilot and flying the best fighter" has always been Chen Liu's dream. In 2015, he bid farewell to his relatives and friends and resolutely rushed from the prosperous city to the desert Gobi, just to drive the advanced fighter plane of the motherland - j-20. Chen Liu's new unit has the reputation of "incubator" of new combat effectiveness. In recent years, it has continuously tested weapons and equipment, innovated tactical methods and tested operational capabilities, which has provided strong support for the strategic transformation of the air force. It means not only changing the concept of training, but also changing the training mode. In order to promote the rapid formation of combat effectiveness of the new aircraft, Chen Liu boldly broke the previous real equipment training mode with single means, and explored a set of information simulation training methods to greatly shorten the generation cycle of combat effectiveness. In two years, he completed the modification of type III new aircraft and became one of the pilots of Tongfei j-20, j-16 and j-10c. Three planes fly together, which is not a simple superposition of numbers "1" to "3". In this process, Chen Liu has experienced dangerous situations such as hydraulic system failure, and each time is a test of life and death. In a test mission, after Chen Liu flew 200 kilometers away from the airport, the warning sound of "low hydraulic pressure" in the cockpit suddenly sounded. If it is not handled properly, there is an organic danger of destruction and death. At an altitude of 10000 meters, Chen Liu was fearless in the face of danger, calmly analyzed the cause of the fault, explored the operation method of the fighter under the fault condition, corrected the course and aimed at the runway to slow down, and finally landed the fighter safely on the runway. "Even if I fight to the last second, I will fly the fighter back." For Chen Liu, fighters are not only national property, but also his comrades in arms who have fought side by side for a long time. Turning to the memorabilia of the Department, from the formation of the army to the initial formation of combat effectiveness, Chen Liu charged ahead every time, whether performing major tasks or participating in war trial training exercises. In 2018, a missile was tested for the first time, and Chen Liu volunteered to carry out the test mission. He worked overtime to learn the knowledge of weapons and equipment, formulated the test firing plan, made an emergency plan, and finally led the team to achieve excellent results in the first hit. In 2021, Chen Liu was ordered to participate in the air echelon flight performance of the General Assembly celebrating the 100th anniversary of the founding of the Communist Party of China. This was the second time he piloted a fighter to accept the review of the motherland and the people. During the 2019 National Day military parade, Chen liuzeng flew a j-20 fighter over Tiananmen Square. After two years, when Chen Liu made a wonderful appearance in the same sky again, his j-20 array has changed from one echelon to three echelons and five fighters to 15 fighters. As a fourth generation aircraft pilot who has grown up step by step from the aviation force, Chen Liu has gone through hardships and strengthened the army dream by dream all the way. When asked why he did so, Chen Liu replied, "as a party member and a soldier, I am willing to work hard to verify more high-performance equipment and defend the security of national airspace. When the war comes, I will go up without hesitation and defend the blue sky of the motherland!" (outlook new era)
