China News Service, Beijing, November 4 (Guo Chaokai) According to China Aerospace Science and Technology Corporation Limited’s news on the 4th, China’s first vertical take-off and landing reusable launch vehicle is expected to be completed around 2025, realizing the full range of vertical recovery and reusable launch vehicle technology. breakthrough.
A high-end forum on aerospace and navigation international engineering technology strategy was held in Chengdu recently.
Wu Yansheng, Secretary of the Party Leadership Group and Chairman of China Aerospace Science and Technology Corporation, pointed out at the forum that "carrying capacity", "reliability/safety", "launch cost" and "development efficiency" are four dimensions to measure the level of a country's access to space; Develop reusable launch vehicles and heavy launch vehicles, further optimize the rocket type spectrum, realize the intelligence of the space transportation system, and comprehensively improve the carrying capacity of China's space transportation system.
Wu Yansheng said that China's first vertical take-off and landing reusable launch vehicle is expected to be completed around 2025, achieving a comprehensive breakthrough in vertical recovery and reusable launch vehicle technology.
At the same time, flight intelligence has become an important direction to improve the reliability/safety of launch vehicles. 2035 will be the era of intelligent launch vehicles. With the empowerment of intelligent technology, launch vehicles will have the ability to sense, learn and adapt to the environment independently to meet high efficiency. , Reliable and adaptable to the needs of complex missions in and out of space, has become one of the solid foundations for the construction of a space power.
Previously, China Aerospace Science and Technology Corporation had revealed that the improved version of the Long March 8 launch vehicle intends to achieve the overall vertical recovery and reuse of the core first stage and booster, which will lead to new developments in China's launch vehicle technology, further reduce launch costs, and increase the market. Competitiveness.
In recent years, China has continued to carry out relevant experiments to reuse launch vehicle technology.
On July 26, 2019, the Long March 2C carrier rocket carried out a fairing/parachute and a sub-stage/grid rudder separation area safety control technology test at the same time during a launch, making China the second successful in the world Countries that have verified this technology have laid the foundation for the subsequent development of launch vehicle landing control and even reusability.
On October 26, 2020, the Long March 2C carrier rocket successfully sent the 3 satellites of the remote sensing 30 group 07 and the Apocalypse constellation 06 into a predetermined orbit in the manner of "one arrow and four stars".
In this mission, the fairing of the Long March 2C launch vehicle was again equipped with the landing zone safety control system, and its main electronic equipment was recovered from the fairing landing zone safety control system during the flight test on July 26, 2019. For the first time in the history of China's space transportation, sophisticated electronic equipment was reused at the "system level".
