The reporter learned from the 200-time launch and innovation development symposium of the Long March series of launch vehicles held in Beijing on the 8th that during the 13th Five-Year Plan period, China plans to implement 120 space launches; Long March 5th, 6th, 7th and 11th The rocket will complete its first flight in two years; China plans to complete the development of heavy rockets in about 15 years.
Lei Fanpei, chairman of China Aerospace Science and Technology Corporation, said at the meeting that China’s Long March series of launch vehicles had implemented 200 launches and put 248 spacecraft into orbit. Especially since 2007, the Long March rocket has entered an important stage of accelerated development, and completed 100 launches in 7 years.
Lei Fanpei said that in the past seven years, the Long March series of rockets have successfully completed high-density launch missions, with an average of more than 15 launches per year. A total of 134 spacecraft were launched into space, effectively guaranteeing the implementation of a series of major national engineering tasks; The reliability of the rocket has been greatly improved. The success rate of the launch has increased from 93% in the previous 100 times to 98% in the last 100 times. It surpasses the United States and Russia and ranks first in the world with the European Union. China has broken through a number of international Leading-edge rocket frontier technology, and actively promote the innovative development of a new generation of rockets.
"The Long March 5, 6, 7 and 11 rockets have entered the critical stage and will complete their first flight in the next two years." Lei Fanpei said, "There are four types of rockets flying for the first time in two years. The space industry will be unprecedented." In addition, he also revealed that China will accelerate the implementation of pre-study of key technologies for heavy rockets, and strive to break through the overall design of heavy rockets in four to five years, as well as 460 tons of liquid oxygen kerosene engines, 220 tons of hydrogen-oxygen engines and Key technologies such as the design and manufacture of the rocket structure of the diameter of about 9 meters; the development of heavy rockets was completed in about 15 years.
Niu Hongguang, deputy director of the General Armament Department, said that China's spaceflight has achieved historic achievements, but the next task is arduous and should be fully prepared for the difficulties. He said that in terms of workload, in 2015, China's aerospace model initially planned 21 launches and two new launch vehicles. During the "Thirteenth Five-Year Plan" period, a total of 120 space launches are expected to be implemented. By then, China's on-orbit spacecraft will reach about 200. In terms of difficulty in development, the Long March 5 and 7 rockets are difficult to develop; the manned space station, the lunar exploration phase III, and the Beidou navigation phase II project contain a large number of new products and technologies; some key projects still have key technologies that are not yet complete. Master, there are risks in terms of quality, technology, and progress.
For China's launching measurement and control capabilities, Niu Hongguang introduced that China's space launching center has expanded to four, liquid rocket launching stations reached nine, and the number of launches was nearly 20 times; it has been built to cover land to sea, domestic to foreign, and ground to deep space. The measurement and control network has the ability to manage more than 150 spacecraft in orbit.
