The three kilometers around the launch center have all been under martial law, and a large number of mechanical guards are constantly patrolling the surroundings. If they find someone approaching, they will be expelled.
After all, this is the first time a rocket has been launched, so Ye Fan invited many highly respected experts in the industry to be stationed and instructed to ensure that nothing went wrong.
On the very side of the launch center, a "steel giant" with a height of 150 meters and a weight of 2500 tons has been established.
This is a large rocket launch tower, shining stars and dots in the dark night.
The largest cantilever of the launch tower, that is, the structure that covers both sides of the rocket before launch is 28 meters long, which can be described as "strong body".
If you look down from the top of the launch tower, you will find that the launch tower and the tower body and cantilever present a "K" shape, and many facilities on the launch tower can be rotated.
This is the design made by Su Ying's team after careful consideration. It is not designed casually, and is closely related to the launch of the rocket.
After the rocket takes off, horizontal drift may occur. In the professional field, this possible drift is called the rocket safety drift.
In order to ensure the safe launch of the rocket, it is necessary to have a certain distance between the launch tower and the rocket to allow the rocket to fly safely.
Because the rocket needs a series of preparations and operations on the launch tower before launching, the launch tower is not close to the rocket.
Therefore, the working platform and service arm on the launch tower are designed to be a rotating type, and the crane is designed to be a boom type.
In this way, the cantilever of the working platform and the crane can be rotated by a large margin before launch, so that various facilities can be close to the rocket while leaving a part of the distance.
Therefore, when launching, leave enough space to ensure the safe launch of the rocket. Before launch, the working platform is closed to enclose the rocket.
At this time, Datang Technology’s rocket launch tower was closed, because the rocket’s final launch preparations were underway at this time.
However, for such a large project, 90% of them use intelligent robots for construction and inspection, and the ratio of human resources is already very small.
Otherwise, the launch center will not be established in such a short time, and it can be quickly put into the rocket launch.
At this time, the cantilever of the launch tower, that is, when the four-segment gyrating platform of the launch tower surrounds the rocket, it can form a closed space for shelter from wind and rain to protect the rocket.
There is also a lifting platform in the maneuvering platform for testers to open and close the doors, unload instruments, connect the plugs of various equipment, test and astronauts enter the cabin.
An aiming window is set on the upper revolving platform to ensure the aiming of the rocket.
On the hundreds of meters high launch tower, there is also this large pendant tower. At this time, the pendant tower is connected to the network, and artificial intelligence is controlling the pendant tower to prepare for the final launch procedure.
In addition to the normal transportation function of the suspended tower, when the spacecraft fails, it can also complete the unloading of the escape tower and the carrier cabin. After the spacecraft has eliminated the fault, the escape tower and the carrier cabin can be lifted and assembled again with the rocket.
Inside the launch tower, various lights were flashing like stars. Through the live broadcast of the live robot authorized by Datang Technology, everyone saw the large rocket inside the launch tower and the spacious launch tower.
On the eve of the rocket launch, the live robot showed various power cables, air pipes, propellant filling pipes, water pipes, ladder climbing and other equipment to audiences across the country.
Thirty minutes later, the launch procedure was completed, and all intelligent robots and the staff under inspection were evacuated.
The audience watching the live broadcast in the live broadcast room became more and more nervous.
We must know that this time the rocket launch did not choose the common Jiuquan satellite launch base, but chose the target location in Jiangcheng.
Jiangcheng is not the same as the Jiuquan Satellite Launch Base. It does not have an advantage in terms of dimensions or other aspects.
Although it was launched in the suburbs, it was only 50 kilometers away from the city. For a rocket that flew into the sky, fifty kilometers was just a distance that could be leaped at once.
Therefore, high-level officials were not allowed to launch rockets in such places. After all, if something went wrong, it would very likely have a serious impact.
However, when Ye Fan took out the electromagnetic defense array, everyone was silent.
After all, this thing is a powerful defensive shield that can block the impact of meteorites. On the day of the natural disaster, everyone is obvious to all. If it were not for the electromagnetic defense array, it is estimated that the large cities along the coast of China would be dead.
So under this guarantee, the top management reluctantly agreed to the rocket launch.
In the eyes of the outside world, Datang Technology is making a brave attempt. After all, this is the first company in the history of the world to launch rockets in urban areas.
Moreover, even if it is a state-owned enterprise, this Datang Technology is still a private enterprise. If it succeeds, it's okay, if it fails, then Datang Technology will be in great trouble.
Twenty minutes before launch.
"D...D...D..."
The rocket launch tower opened slowly. This opening process was very slow, and it opened for nearly ten minutes.
It was not until the launch tower was opened that all the audience saw the true face of the rocket.
The rocket's name is "Qinglong". On the rocket's arrow, four characters are written in bold red font: "Datang Aerospace".
At the same time, the shape of this rocket is much larger than other rockets. From the paper data, it is normal for the Blue Dragon to be so big.
Judging from the paper data, this is simply the largest carrier rocket in human history, with a height of 130 meters, a take-off weight of 4,200 tons, and a total thrust of 3940 tons~EbookFREE.me~The lunar orbital carrying capacity is 60 tons, near the ground. The orbital carrying capacity is 150 tons.
This is a three-stage rocket consisting of the first stage, the second stage, the third stage, the instrument bay and the payload.
The first stage is 50 meters long and 15 meters in diameter. At the end, the diameter increases to 18 meters. The tail section is equipped with 4 stabilizer wings with a wingspan of about 25 meters.
The first stage uses five engines, the propellants are liquid oxygen and kerosene, and are stored in two ten-meter-diameter aluminum propellant storage tanks.
The second stage is 25 meters long and 10 meters in diameter. It uses liquid oxygen and liquid hydrogen propellant. One uses five secondary engines.
The third stage is 18 meters long and 6.6 meters in diameter. It uses a three-stage engine with liquid oxygen and liquid hydrogen as the propellant.
This is like a giant.
It is like a guard, standing quietly in the night.
