1February, 983, Xing Qiujue became the president of the Fourth Hospital. He led all the staff wholeheartedly and launched a general attack on high technology, vowing to win the model of that year and carry out ground hot test at the end of the year. This is the first time that China has developed an organic fiber wound shell. The design, technology and technology are difficult, but the factory building and equipment conditions are very poor. Xing Qiujue often goes deep into factories and research institutes to encourage employees to adhere to a scientific attitude and dare to take the lead in scientific research. To this end, 43 workers modified the domestic first-generation mechanical winding machine for winding the secondary FRP shell; The technical problems such as formula, tensile test and sand removal were studied repeatedly, and a large composite shell was packaged in a short time. ?
In order to make the first ground test of two new types of engines at the end of that year, all contractors took the time to complete the tasks of each process. However, when a product is charged, the problem of shell debonding suddenly appears. Dean Xing came to the scene and said seriously, "This will not work. Don't send it for test run under the condition of debonding. We must come up with a solution as soon as possible. " Soon, the suggestion was put forward, that is, dig out some medicine in the shell first and then repair it. At that time, XX tons had been loaded. Suppose a person got into the shell and cut the medicine with a steel knife. Many people feel unsafe for fear of causing friction explosion. Dean Xing discussed its feasibility extensively with front-line technicians. A craftsman surnamed Xiong said that he used a steel knife to cut medicine. Because the steel knife is sharp and hard, the friction is small and it is not easy to have an accident. Dean Xing thought it was reasonable and agreed to implement this plan, and said that he never left the scene during the process of digging medicine. It was summer, and the medicine in the small shell was pungent and sultry. After Dean Xing entered the shell for the first time to see the truth, the master began to control the medicine, changing one person for half an hour, and then changing it every 15 minutes. After two days of continuous work, the medicine in the debonding part was dug out, and the whole digging process was smooth and safe. Subsequently, the debonding part was repaired to meet the design technical requirements.
1983 65438+On February 25th, the repaired engine was hot tested as scheduled. After the ignition command was given, the roar shook the earth, and the dragon-like flame spewed out from the tail of the nozzle. All kinds of test instruments are normal and the trial operation is successful. Three days later, a new large engine ignition test was conducted, which was also a complete success! ?
Hearing the good news, Zhang Aiping, Deputy Secretary-General of the Military Commission, took a day off from his busy schedule and made a special trip to the Fourth Hospital on June 5438+0984+1October1May to watch the commissioning video and the engine parts after the commissioning with great interest. He said happily: "The success of the first and second stage tests is a new major breakthrough in solid rocket technology, which has enabled China's launch vehicle technology to enter a new generation." He instructed: "We should also pay close attention to the third level." Xing Qiujue asked Zhang Aiping to write an inscription for the Fourth Hospital. He happily wrote eight words: "Saving the day, infinite wisdom". Dean Xing issued a military order to him to ensure that the third-stage engine would be tested in the first half of the year.
To this end, Xing Qiuji traveled a long way and led the staff of the whole hospital to develop a three-stage engine, which was successfully tested as scheduled on June 30 of that year, making the engine technology a big step forward to the world advanced level. To this end, the people of the Fourth Hospital are still proud of their series of scientific and technological achievements, climbing the peak in the aerospace field and taking off the pearl of victory.
Because the successful test run of large engines laid a technical foundation for the establishment of strategic missiles in the future, after the launch of the "most important" model, the above two large engines were used as the first and second stage engines of the missiles respectively. As the director of the Science and Technology Committee of the Institute, Xing Qiuji presided over and participated in the technical review and comprehensive technical review at all stages. After the delivery of this model, three consecutive test flights were a complete success. When a large missile team passed Tiananmen Square at a ceremony to celebrate the 50th anniversary of the founding of People's Republic of China (PRC), the people of China were very excited, and the ball marker in front of the TV set was in tears.
