"The capacity of the launch vehicle is large, and the space stage is large. The ability to enter the space is the premise and basis for the exploration and utilization of space." Member of the National Committee of the Chinese People's Political Consultative Conference, the former party committee secretary of the China Academy of Launch Vehicle Technology, Aerospace Science and Technology Group Liang Xiaohong On the 2nd, he said in an exclusive interview with Xinhua News Agency.
At present, China's heavy-duty launch vehicle has completed deepening the argument. If a series of key technologies achieve breakthroughs and related work is progressing smoothly, it is expected to achieve the first flight within 15 years. This will greatly enhance China's ability to enter the space autonomously.
At present, the United States and Russia are actively occupying the commanding heights of space and restarting the development plan for heavy-duty launch vehicles. Europe, Japan, India, etc. are also competing to promote the research and demonstration of new large-scale launch vehicles. China also needs a more capable launch vehicle.
"In the blueprint of the researchers of the China Academy of Launch Vehicle Technology, the heavy-duty launch vehicle has a diameter of nearly 10 meters and a total length of nearly 100 meters. The carrying capacity is more than five times that of the existing rocket, which is more than the United States under development. The carrying capacity of a generation of launch vehicles (SLS) can fully meet the needs of future deep-space exploration missions such as manned lunar exploration, Mars sampling return, and solar system planetary exploration, ensuring China's voice in future space exploration and greater and farther space. "Liang Xiaohong said.
It is no easy task to build such a heavyweight rocket. The scientific and technical personnel must solve the larger thrust liquid oxygen kerosene engine technology representing the world-class scientific research level, the larger thrust liquid hydrogen liquid oxygen engine technology, the larger diameter arrow design, manufacturing, testing technology, and the overall design of the rocket. "Total" is a series of problems represented.
"If these cutting-edge technologies break through, they will be able to better promote the leap-forward development of China's new materials, new processes, new devices, new equipment and other basic industries, serve the transformation and upgrading of China's manufacturing industry, innovate and develop, and help the aerospace power strategy and 'Made in China'. 2025' landing," Liang Xiaohong said.
