Long-March Rocket Technology Meets International Standards
( 2003-05-31 13:57) (china.org.cn)
With the successful launch of
the Beidou navigation and positioning satellite, the Long-March launchers have
raised the success rate of this Chinese technology to 90 percent. Chinese
aeronautical experts said the overall technology embodied in China's Long-March
carrier rockets has already met international standards.
The successful launch of the Beidou navigation and positioning satellite has
raised the success rate of the Long-March launchers to 90 percent from 89.8
percent. According to relevant statistics, the success rate of America’s Delta
carrier rockets is 94 percent, the success rate of the European Ariane carrier
rockets is 93 percent, and the Russian Proton carrier rockets, 90 percent.
Since the Long-March launcher put China’s first man-made satellite,
Dongfanghong (Red East) 1, into orbit, the carrier rockets have successfully
sent 52 different Chinese-made satellites, 27 foreign satellites and four
Shenzhou space shuttles into space. Over the past 14 years, China’s astronautic
technology has developed rapidly and continuously. The Long-March carrier
rockets alone have made 50 launches. The 28 continuously successful launches of
the Long-March carrier rockets since October 1996 show China’s astronautic
technology capability.
From propulsion in normal to low temperature, from series connection rocket
to carrier rocket, from launching satellite load to launching manned spaceship,
Long-March launchers have passed many different technology experiences.
Now the Long-March family has 12 different kinds of rockets, and they are
capable of launching spacecraft in different orbits.
According to experts, in order to raise the rockets’ competitive edge in the
world launch market, scientists are actively researching and developing a new
carrier rocket that is non-polluting, low cost, reliable, adaptable and secure.
