Xinhua News Agency, Beijing, March 2 (Xinhua Bai Guolong, Jiang Xiao China’s heavy-duty launch vehicle development work has been officially launched early key technology research, program deepening demonstration, the current rocket engine technology research has made a breakthrough.
‘At present, the world’s space power have to restart the heavy carrier rocket development plan, Europe, Japan, the United States, the United States, the United States, the United States and other countries, India is competing to advance the research and demonstration of the new large launch vehicle, while Chinese astronauts have stepped up their own heavy-duty launch vehicle.
China Aerospace Science and Technology Corporation, a director of the Institute of the overall designer Qin Xudong said that China’s heavy rocket early key technology research, program deepening demonstration work in June 2016 formally approved the project, the main research content for the ‘one total three’: a total That is, the overall technology and program optimization of heavy rocket, three large 10-meter-scale large-diameter structure of the design, manufacture and testing, 480 tons of large thrust liquid oxygen kerosene engine, 220 tons of large thrust hydrogen and oxygen engine.
At present, the two kinds of large thrust engine research progress smoothly.Tan Yonghua said, 480 tons of liquid oxygen kerosene engine has completed the first generator – turbine pump test, the test to achieve the desired purpose, through the test to verify the engine system and component program Feasibility, marking the 480 tons of liquid oxygen kerosene engine development key technology research breakthrough, while the 220-ton high-performance hydrogen and oxygen engine has also completed a number of components of the program detailed design, the components of the development and testing work.
Prior to the National Space Administration deputy director Wu Yanhua has introduced China’s heavy-duty launch vehicle to be named Long March 9, plans to achieve the first flight in 2030 or so.
Qin Xudong said, compared to the diameter of 5 meters of the rocket Long March 5, heavy carrier rocket Long March 9, the development of more difficult and higher requirements.
‘Rockets to a certain extent, a lot of things become complicated, such as routine modal test, before the Long March is the rocket hanging up to do, but the heavy rocket can not hang up, it is too big, This is what we want to research the content. ‘Qin Xudong said.
Tan Yonghua introduction, the Long March 9 heavy carrier rocket design thrust of more than 3,000 tons, near-Earth orbit carrying capacity of 100 tons or more, the earth transfer orbit carrying capacity of 50 tons or more, to meet the future manned moon, Mars exploration and further Of the deep space exploration needs.If the first flight success, is expected to become the world’s largest carrying capacity of the rocket.
