Korea “Lo Lo” rocket exploded moments

World Wide Web (microblogging) correspondent Chang reported in the “Temple” After the successful launch of “Shenzhou 8″ spacecraft to the international community to look again to invest in China. Global Network reporter interviewed Han Guoren Holland School of Mechanical Engineering Aerospace Engineering Professor Cui Donghuan (sound), he said, docking is a super advanced technology to determine the level of technology can not just success.

When asked how to treat the “Shenzhou VIII” and “Temple” of the rendezvous and docking test, Professor Cui Donghuan said, “because of its technology in this area are not many open only to understand ‘Temple One ‘has been successfully launched, so I can not exactly determine the technical level of China’s butt, “” but, to judge a country’s level of technology can not just success stories, failures with relevant experience must also be reviewed. ”

He stressed that the two spacecraft docked to achieve in the universe, the body requires between ground personnel close to the flight speed, distance, coordinates and other properties of ultra-precise control. Close to the speed if too fast, the two aircraft may conflict; and too slow, it is possible in the docking process waste too much time. In addition, the acceleration control, and precise control of position coordinates of each other is also very important. When flying close to the body in two, not only horizontally, but also compound rotary movement.

In short, control of the aircraft position, velocity and acceleration control belong to the technical level of the “frontier.” Therefore, the ability to effectively fulfill the command of hardware facilities, such as posture control computer, reaction wheel system (reaction wheel), ultra-precision propulsion is particularly important, which is what the process of docking in space vehicles need to be solved.

to master space docking technology has been the country, Professor Cui Donghuan said: “The United States and Russia are known to master space docking two countries, but as far as I know, there are technical cooperation with the United States Japan and other countries are also being developed and docking technology, and the universe trying to butt their flight module. “★
