Long March 5 rocket using China 's newly developed hydrogen and oxygen engine

Long March 5 rocket is China's largest active capacity, the largest rocket
Xi'an, August 19 (Reporter Tian Jin) at the Xi'an Aerospace Base of China Aerospace Science and Technology Group held a meeting on the 19th Long March 5 first flight into the mobilization meeting. The Institute for the Long March 5 rocket to provide core level, two, boost, auxiliary power system and other engines, the newly developed two models of hydrogen and oxygen engine as a rocket one or two main force, the first commitment to flight test mission, will achieve China 's hydrogen and oxygen engine development technology across. Long March 5 rocket is China's largest active capacity of the rocket, the largest rocket, 56.97 meters high, the core diameter of 5 meters, the maximum takeoff quality of 867 tons, carrying capacity to reach the Earth synchronous transfer track 13 tons, 25 tons of near-Earth orbit. As a new generation of large-scale launch vehicle with non-toxic and non-polluting propellant in China, the rocket is also a milestone and important symbol of the upgrading of China's launch vehicle. It is responsible for the comprehensive strength of China's space transportation system, Meaning is very important. China's future space station construction, lunar exploration and other deep space exploration will use the implementation of the rocket. According to reports, the newly developed two models of hydrogen and oxygen engine as a rocket one or two main force, is the first commitment to flight test mission, will achieve the development of China's hydrogen and oxygen engine technology across. Boosted the use of eight 120 tons of liquid oxygen kerosene engine, in the Long March 7, Long March 6 flight performance in the first flight perfect. For the upper level of the two main engines, a number of top-level attitude control engine to assume the "space ferry" role, the payload accurately sent to the scheduled track. China Aerospace Science and Technology Group Liu Zhiyuan, president of the Long March five rocket is the first time in China in recent years developed a new generation of rocket engine comprehensive system assessment, the hospital has sent more than 60 scientific research personnel composed of the test team to the launch site task.
