China successfully launched the Long March VII in the early morning of the Wenchang Aerospace launcher in Hainan (12th) in the early morning of Hainan.The Rockets were developed by the China Lauding Rockets Technology Research Institute of China Aerospace Science and Technology Group, and the test No. 9 was successfully sent to the scheduled track.
According to the China News Agency, the successful launch of the long -seven changes to the Rockets has opened the curtain of China's new generation of carrier rockets in 2021, marking the Chinese new generation of medium -sized carrier rocket family to add new members.The rail load capacity is blank.This launch is the 362th launch of the Long March series of rockets.
Long -seven -changing rocket is a three -and -half rockets formed by the three -semi -semi -rockets formed with the three -semi -class rocket -class combination with the Long March VII Rockets. It is the main structure of the new generation of medium -sized carrier rockets.The rocket arrows are 60.1 meters long, with a take -off weight of about 573 tons. The carrier capacity of the earth's synchronous transfer orbit is not less than 7 tons.
At present, China's main launch vehicle with high -track launch capabilities can send 5.5 tons of valid load to the earth to transfer orbit, while the successful development of the long -seven changes rocket fills 5.5 tons to 7 to 7 to 7 to 7The blank of ton carrying capacity.Meng Gang, chief commander of the long -seven modification rocket, said that the successful launch of the long -seven -changing rocket has further enriched the spectrum of the Long March series of carrier rockets.The upgrading of satellites is of great significance for the construction of the aerospace power.
In the future, on the simultaneous transfer orbit of 36,000 kilometers from the ground, the long -seven -modified rocket with 7 tons of carrier capacity will and the long three -line rocket with a 5.5 -ton carrying capacity, the long five rockets with 14 tons of carrying capacity willTogether, forming a more optimized and reasonable layout, which will vigorously enhance the ability of Chinese aerospace to enter and exit space.
"The successful transformation of the Long March 7 is an important milestone in the development process, but this is just a new starting point. The follow -up work is far away, and we still need to work hard." Meng Gang said.According to the Chinese Lauding Rockets upgrade strategy, the new generation of carrier rockets will initially achieve the update of the active rockets around 2025.According to the current task arrangement, the task arrangement is full before 2025, and the task will be launched three to time each year.
Follow -up, the long -seven -changing rocket will also develop a larger diameter rectifier structural type according to the needs of the task; based on the long -seven modification rocket, through the increase of the above -level solutions, the zero -orbital dumping satellite launch tasks will be achieved.Detective fire exploration and asteroid detection tasks provide a solid guarantee for the construction of Chinese aerospace power.
