The technology behind a beautiful show
Space technology helps Olympics ceremony soar2008-08-09
BEIJING - China's progress in the area of space technology contributed to the successful Olympics opening ceremony, said a senior engineer in charge of the ceremony's engineering design here on Friday.
"The engineering design at the opening ceremony borrowed many of the latest space technologies. They ensured the stable operation of thousands of devices," said Zhou Fengguang, head of the Engineering Design and Research Institute of the People's Liberation Army General Armament Department.
The main cauldron of the Beijing Olympic Games looked like a bird's eye view of a huge musical note. The design, simple but beautiful for the audience, was complicated for the engineers.
"First, we had to make sure a cauldron of this shape could stand so high over the National Stadium," said Zheng Zhirong, the engineer in charge of its design.
Experts decided to send the cauldron into a wind tunnel to test its stability, just like they did with the Shenzhou spacecraft.
Technologies used to build space vehicles were also applied to the engine control system of the cauldron, he said.
To keep it on track as it moved, monitors were installed at several key joints, from which they simultaneously sent back data to help control the speed and direction.
"The whole process was the most complicated, with the most components, that I have ever seen," said Zheng, who's been designing rocket launching systems for about 20 years.
The control center of the opening ceremony was equipped with the "Shenzhou 4000" control system that was used during space missions.
"About 800 devices were in operation at the same time. If one had a problem, the ceremony could not pause until you fixed it," Zhou said. So all key systems had back-ups.
Engineers also equipped the control system with a "black box" to help technicians detect and repair any problems as quickly as possible.
"The technology support system of the opening ceremony was a challenge as big as a spacecraft launch," said Zhou. "There was no room for error."
Space experts also contributed. They developed a computer system for scheduling that could monitor every step of the three-and-a-half-hour ceremony and alert the directors to the upcoming one in advance.
China sent its first manned spacecraft into space in October 2003 and will launch the third one in October.
"Science and art are two sides of a coin," said Zhou. "I believe more space technology will be applied in civilian sectors and benefit people in their daily lives."

BEIJING, Aug. 10 -- With huge LED screens, eye-catching lighting systems and multimedia video shows, one of the hallmarks of the Games' opening ceremony was its use of cutting-edge technology.
This was thanks to the efforts of Yu Jianping, director of the technology group for the opening ceremony, who led a 500-strong team of experts
From the elevated platform to the video system, the creation team worked hard to ensure that the whole ceremony went without a hitch.
"The technology used at the Games' opening ceremony was some of the most complicated in history," Yu said.
"One of the features of the ceremony was its perfect combination of advanced technology and great originality."
At the event, a 147 m by 22 m LED screen, one of the biggest in the world, was laid at the center of the stadium. There was also a 36-m long by 30-m wide structure, with a total of 11 separate elevated platforms.
"Since all of the facilities were completed on June 10, we had only two months to tackle any problems," Yu, who is also the deputy designer of Shenzhou VII, China's third manned spacecraft, said.
On Yu's initiative, modern technology was introduced to many aspects of the ceremony. Apart from the huge LED screen and elevated platform, the globe that rose up at the end of the performance was another highlight.
With a diameter of 18 m, the globe weighs around 16 tons and can be raised to a height of 24 m. A total of 58 actors performed at the globe, with half of them being upside down for part of the time.
"It was the first time such a huge globe was used in China," Yu said. "The material on its surface was a kind of flexible aluminum."
Their other creations included the huge scroll, 20 mm thick and weighing around 800 g, and the digital direction and control system.
"Apart from the communication system, all of the technology we used was developed by Chinese companies," Yu said.
