In large-scale development of the rocket, the state deputy chief lunar exploration project, is currently China Academy of Launch Vehicle Technology architect Long Yue Hao carrier rocket series academicians have used wake up early, get up late, vividly depicts our large rocket development of the situation. He said that China's rocket carrying the coefficient in the mid-1990s to reach third in the world. However, due to various reasons, the past 10 years, China's rocket technology is not synchronized to achieve greater breakthroughs, could not continue to maintain their lead. Thus, to adapt to the development needs of China's aerospace industry, the development of large rocket technology is imminent now, Chinese Long March series of carrier rockets in geosynchronous orbit carrying capacity of the largest is the Long March III carrier rocket, carrying capacity of 5 tons; near-Earth orbit carrying capacity of the largest of the Long March II F carrier rocket, carrying capacity 9 tons or so. But this is far from meeting the future development of China's aerospace industry needs. The East is Red V of the next generation of communications satellites in the next 20-ton long-term manned space station, return lunar probe, deep space probes, super-heavy-duty applications satellites, as well as future lunar exploration project, are required to carry the amount of more large rocket launch. Long Yue Hao academician said: The new generation of carrier rockets will significantly enhance our ability to enter the space. Chinese Academy of Engineering, the Shenzhou spacecraft's first chief designer Qi Faren also believes that the development of very large rocket is necessary: If there is no rocket , our country's manned third step can not be achieved, the second step can not be achieved lunar from lunar future development, from manned development, China needs a rocket with a larger carrying capacity.
Since large-scale rocket basic officially approved project, the Chinese scientists to enter engineering design stage, and the development of a variety of devices. In the technical research, the engine, the rocket has been hailed as big heart of the research is very important. Since the late 1990s, China to begin developing the 120-ton and 50-ton liquid oxygen kerosene engine liquid oxygen hydrogen engines. At present, China has mastered a large staged combustion cycle liquid oxygen and liquid oxygen kerosene engine series of key technologies hydrogen engines, and became the second after Russia fully grasp the high-pressure liquid oxygen kerosene staged combustion cycle liquid rocket engine core technology of the country one can not help Curious, compared with China's existing launch vehicles, launch vehicles What are the characteristics of large future it? nike shox turbo 13 womens
Long Yue Hao in the Prospects of development of expendable launch vehicle, the article pointed out, China's new generation of carrier rockets follow the one family, two engines, three modules the general idea, modular combinations. Long March V 'will use liquid hydrogen and liquid oxygen kerosene and liquid oxygen propellant, the propellant non-toxic and non-polluting high reliability. China Academy of Space Technology researcher Pang Zhihao interview In an interview with the author, said, It is reported that the Long March V biggest near-Earth orbit carrying capacity will reach 25 tons, geosynchronous transfer orbit maximum carrying capacity will reach 14 tons. Long March the 6th. Quick launch vehicle for the new, with a height of 700 km sun-synchronous orbit of not less than one ton carrying capacity. Academician of the rocket trajectory design experts, China Academy of Launch Vehicle Technology Department researcher Yu Menglun comes to the overall design, Long March the 7th Near-Earth orbit with 13.5 tons, 700 km sun-synchronous orbit 5.5 tons carrying capacity of China's space experts pointed out that, at present, the world's next-generation carrier rocket engine or hydroxide liquid oxygen kerosene engine as the active asics gel kayano 18 womens
force; And, in order to enhance the launch vehicle mission adaptability, countries actively develop upper stage technology, the formation has a variety of carrying capacity, can perform a variety of tasks carrier rocket series; completion by the major mainstream launch vehicle into space missions, but also actively developing launch vehicles for special applications And our country is still a Long March carrier rocket family series, each carrying models are derived from the development of specific requirements, the model state of technology vary greatly, there are also carrying capacity overlapping phenomena, however, China made a large launch vehicle breakthrough can not be underestimated. Aerospace Technology Group six Dean Tan Yonghua said that China is developing the level of the Long March V rocket developed by the European Ariane 5 rocket level equivalent, to some extent, even more powerful.
