3 minutes and 08 seconds, 430 meters away, so that the Olympic torch lit.
This is Zhang Xiangnong's biggest wish to join the opening ceremony of the project team. He led the guard rail car running group since landed on the roof at the bird's nest, for the opening ceremony and ignition specially laid on the runway sprint running. Different from the center of the bird's nest is 400 meters standard runway, the runway to the bird's nest ceiling is longer, more difficult to run, because the car they escort, is driven by the opening ceremony of the Beijing Olympic Games torch hand Lining flying stroll, lit the main torch of core power.
Once the rear of the track vehicle power failure occurs, they will use their own arm to promote the weight of 650 kg of rail cars, let Lining continue to fly.
In the night of August 8th, 4 billion viewers around the world watched, Lining soar with electronic auspicious clouds to walk on air reel, 3 minutes after the success of the Beijing Olympic torch lit. In the bird's nest ceiling command Zhang Xiangnong, finally breathed a sigh of relief, he led the team of 11 people, and finally successfully completed their mission.
In fact, Zhang Xiangnong's research team, the total equipment design institute (hereinafter referred to as the Design Institute) has long been well known. Dean of Design Institute Zhou Fengguang told reporters that they have been involved in the completion of a series of national key projects, the most famous is the Shenzhou six launch tower opening and closing equipment.
In 2008, Zhou Fengguang led the team, will assume the opening ceremony of the Beijing Olympic Games on the ground stage machinery and equipment design, production, installation, operation and operation tasks. The bird's nest over the rail car at the beginning of planning, just a general equipment, but when the opening ceremony of the "flying" ignition is determined, the Design Institute of the more than and 30 people, Zhang Xiangnong in the organization, around the car and began their journey of the Olympic games.
430 meter journey
Flying ignition program, the setting of the electronic cloud scroll start time of 3 minutes and 08 seconds, the top of the bird's nest, the special guard runner, but also must follow the track to complete the sprint in the corresponding time.
Typically, 3 minutes and 08 seconds to run the 430 meters away is not difficult for the players trained with regularity is much easier.
But let the team unexpectedly, boarded the nest at the top to see the track terrain, they realize that this is a difficult task: track the bird's nest ceiling 430 meters around the inner perimeter, but the gap is nearly 10 meters in height.
Due to the existence of downhill, rail cars to uniform speed around the field for a week, in different sections of the required power on the strength of points. This requires more power on the back of the car, in several uphill road, cars must increase the output power, at this time, the power car is likely to malfunction, and restart takes 6 seconds.
But the opening ceremony must be absolutely safe, and Lining's walk can't stop. Rail car protection running group mission, is in the event of a sudden situation, with their own arm to promote the rail car, driving the pace of Lining continue to move forward, for the car to fight for 6 seconds to restart time.
In addition to the height of the gap, 430 meters high difficulty runway, to protect the running group has brought greater challenges. On the side of the car running track, with a width of only seventy or eighty cm of the tunnel, the depth with the terrain and shades. When Lining not take the occasion, supporting run group members is in this special "runway" follow the rail car forward, paved by steel plate tunnel on the ground, every 2-3 meters with steel diaphragm a about 15 cm.
Due to the high degree of confidentiality of the opening ceremony, all training arrangements in the evening. Night training, due to not see the tunnel pavement, players often in training by some steel head tripping, "black and blue is more", a player injury is he rested for three days.
Finally, however, the team finally came up with a coup, placed in the barrier after the fluorescent rod, training significantly reduced injuries. At the same time, in order to measure the time, they are still in the tunnel every 1 meters set the logo.
Track on the slope of several sections of the road, the probability of a mechanical failure of the vehicle is relatively high. To this end, the protective run group at the beginning of 100 meters, 245 meters and 270 meters to carry out targeted training.
Special celebration of bird's nest ceiling
In August 8th, the bird's nest became the focus of global attention. The final ignition, it is the focus of the focus.
This will undoubtedly bring great pressure on the rail car protection run group. 4 in the afternoon, all the players will be gathered to the bird's nest ceiling, but they have no chance to drill again. On the day of the opening ceremony, the bird's nest gathered nearly more than and 200 staff members of each team.
Zhang Xiangnong asked the members of the team to run over and over again in their heads, and to examine their various equipment - backpacks, fluorescent rods, military kettles, and towels. Once the rainy weather, towels can be used to wipe the track.
The night close to 24 points, when the spotlight on the Beijing Olympic torch hand Lining body, control director issued to enhance the password, Lining soar, after reaching a predetermined position, supporting car running group began a journey of their most critical.
100 meters, 245 meters and 270 meters, the most difficult of the three nodes are successfully passed.
When Lining finally arrived at the place where the main torch, the stopwatch in the hands of the figure is 2 minutes and 59 seconds to display the 87. burst into a blaze
