China's solid carrier rocket development is steadily advancing, is expected to make its first flight next year
Liang Xiaohong, member of the National Committee of the Chinese People's Political Consultative Conference and secretary of the Party Committee of the China Academy of Launch Vehicle Technology, revealed to reporters on the 2nd that the development of China's first solid launch vehicle, the Long March 11, is progressing steadily.
Liang Xiaohong introduced that there are 5 stages of rocket research and development. The Long March 11 rocket has now completed the key technical research and development work in the program demonstration and program design stage. It is currently in the third stage-initial sample design, which is expected to be within this year Can enter the fourth stage, which is the sample stage, to make full preparations for the subsequent first flight. "This year we will also conduct supplementary experiments on some of the technical problems exposed at the initial sample stage at the sample stage, and we will organize production in the future." Liang Xiaohong said.
"The development of the first solid launch vehicle not only filled the gap in China's field, but more importantly, provided China with a basic means of transportation to quickly enter space, and provided strong support for China's future handling of emergency and emergency relief." Liang Xiaohong said .
He also revealed that China's Long March series of launch vehicles has successfully launched more than 170 times, and the solid rocket launch is the first of its kind. The advantage of the liquid rocket is that it has a large carrying capacity, which can reach 5-10 tons, but the disadvantage is that the acceleration time is long, and the entire process from testing to launch takes 20-50 days. Although the solid rocket has a lower carrying capacity than the liquid rocket, its biggest advantage is that after receiving the launch order, it can be completed within 24 hours from the test to the launch. "The solid rocket ’s rapid response capability can respond well to sudden disasters. Communication and observation tasks facilitate targeted measures. "
The Long March 11 launch vehicle system consists of a solid launch vehicle and a launch support system. The first stage uses China ’s largest solid rocket engine with thrust, and can tow the development of large solid engine and launch vehicle solid booster technology.
