As the Spring Festival approaches, many people have already embarked on their return journey or immersed themselves in the joy of the festival, but the laboratory of the School of Control Science and Engineering at Dalian University of Technology is still busy. Professor Zhao Jun and his team of teachers and students are working hard to achieve a breakthrough in the "reusable testing" technology for key components of reusable launch vehicles. In the center of the laboratory, Zhao Jun stared intently at the jumping data on the screen. On the whiteboard behind, formulas and flowcharts are densely written, witnessing the team's months of day and night research and development. Reusable launch vehicles can significantly reduce launch costs and improve mission turnover efficiency. It is very important to ensure the safety and reliability of key components of reusable launch vehicles in multiple uses. These subsystems must be thoroughly inspected before each use, "Zhao Jun said. ”PhD student Yang Ruizhe chose to stay at school during the Spring Festival holiday to ensure the progress of the experiment and work side by side with the team. Zhang Zhenyu, a master's student who also stayed on campus, said, "I am fortunate to have been exposed to the most cutting-edge and urgent technological breakthroughs in the country at school. Everyone is holding back their energy and hopes to invest more time to truly use the 'wisdom' in algorithm design." He pointed to the densely packed curves on the screen, "The timing subsystem we are responsible for is the 'nerve center' that commands the rocket. Currently, the equipment has been validated on key components of a certain type of rocket, reducing the detection time from 'hour level' to 'minute level', and the efficiency improvement is very significant!" As the Spring Festival approaches, the team's atmosphere is tense and orderly. Everyone has clear division of labor, some are responsible for data analysis, some are responsible for algorithm optimization, and some are responsible for system debugging, with each link closely connected. In the laboratory, the sounds of keyboard typing, instrument operation, and team discussions interweave to form a special "scientific research march". (New Society)
