Vol 2 Chapter 704: Promising "child"

Wu Hao's remarks really aroused the fighting spirit of everyone present, and also made everyone see Wu Hao's huge space program.
At the thought of being able to participate in this project, everyone was excited.
Looking at the countdown card on the wall, Wu Hao couldn't help saying: "It's less than thirty hours away from the launch."
Yu Chengwu nodded and said: "
According to the meteorological satellite cloud image and the current weather data of the whole country and the entire region, there will be a launch window from 18 o'clock to 20 o'clock tomorrow evening. We plan to choose the opportunity to launch during this period.
If the launch is terminated, it may be a few days later. "
Wu Hao nodded, then looked at the rocket monitoring screen in the middle of the big screen and said, "Is the rocket ready for anything?"
Zhou Xiangming nodded and said: "Because the new semi-solid foam propulsion fuel developed by us is used. This fuel is more convenient to store than conventional liquid rocket fuel, so the fuel has been filled as early as three days ago.
In addition, we have conducted two systematic tests and two launch exercises, and are now conducting the third systematic test and launch exercises.
It is expected to be completed at night and can be transferred to the launch procedure. "
Yu Chengwu added: "We have gone to the area where the rocket wreckage may fall, doing ideological work for the people, and evacuating during launch. In addition, we also have Beidou locator installed on the rocket, which can track in real time. The specific location of the rocket's wreckage, so that it can be disposed of as soon as possible.
In addition, we also cooperated with the satellite measurement and control centers in Anxi and Daocheng. They tracked and monitored the flight trajectories of rockets and satellites, and transmitted them to me in real time.
At the same time, the data of this launch and the tracking and monitoring of the two satellite measurement and control centers will be uploaded to the Beijing Aerospace Flight Control Center for real-time monitoring and command.
Of course, under normal circumstances, they will not interfere with us unless there are special circumstances. "
"What about the satellite?" Wu Hao nodded and asked.
Yu Chengwu now replied: "The representatives of the developers of the three satellites have come. The final commissioning of the satellites is underway these days. Do you want to see them?"
Wu Hao smiled and shook his head: "Forget it, no special arrangements. It should be able to be encountered when watching the launch tomorrow, and then just say hello."
Hearing Wu Hao say this, Yu Chengwu also nodded and stopped talking.
After chatting for a while, Zou Xiaodong suggested that he wanted to go to the rocket launch site, and this also caused other casual personnel's interest.
It stands to reason that after the completion of the refueling of the rocket fuel, other idlers are not allowed to approach. However, they use a new type of semi-solid foam propellant fuel, which is relatively reliable in safety.
So Yu Chengwu immediately agreed to their request, and then everyone took a few convertible off-road vehicles at the base and drove to the rocket launch site.
The launch site is about two or three kilometers away from the base, and the terrain is relatively flat. The sand dunes have been flattened. Therefore, Lao Yuan can see the launch tower and the white and blue rockets on the tower.
Although the rocket is less than thirty meters, the closer it is, the more people are shocked by his majestic body. It is difficult to imagine that such a large rocket can only transport less than three tons of items to low-Earth orbit. It has to be said that the cost and resources of humans flying into space in the future are absolutely huge, which is why the rocket launch payload is so expensive.
After arriving at the launch site and wearing a hard hat, the crowd was finally able to look up close at the launch vehicle that had been established on the launch platform and was about to be launched.
Looking at the rocket, Yu Chengwu and Wu Hao could not help softening their eyes. That kind of feeling is like looking at the children in your own family, and it's still a child with a good life.
"This rocket is our horizontal assembly in the base's final assembly test plant and the first test. After the test is completed, it will be handed over to our transport vehicle to transport the rocket through the hardened road surface of our base and launch site to The launch site, then erected on the launch platform.
Compared with the vertical assembly, vertical transshipment and horizontal assembly transshipment adopted in our country, the technical difficulty and requirements of horizontal assembly transshipment will be much lower, and the corresponding cost will be much lower.
Of course, the entire transshipment process is actually very complicated. For example, the hardened pavement we just walked on was paved with great effort.
Don't underestimate this road, the construction is very difficult, and its construction cost is enough to lay two airport runways. "
Yu Chengwu saw the surprised and affectionate smile of everyone and said, "Yes, it costs a lot. Because this road should not only be straight, but also as smooth as possible. The horizontal drop of the entire road surface, we control it at five millimeters, which is A fairly high standard.
In other words, from the end of the road to this section, the drop is less than half a centimeter.
Secondly, it requires the road to have super high anti-subsidence and anti-pressure and anti-load capacity. Several hundred tons of rockets have to pass by from above, and they have very strict requirements on the road and the foundation under the road.
This may be nothing in the mainland, but this is a desert, with sand beneath it, which is very easy to sink. Therefore, when building roads, we have to drive the pile foundation first, and then build the road on the pile foundation, which is the same as we are building a bridge to a very high standard.
Finally, this is the rocket's delivery vehicle. We introduced the world's most advanced self-modular transport vehicle. This car not only carries heavy loads, but can also be modularly assembled as needed. UU reading www.uukanshu.com increases the length arbitrarily.
This means that we can transport longer and heavier rockets in the future. "
Speaking of which, Yu Chengwu smiled a little embarrassedly: "But according to the latest fixed by the aerospace authority, medium and heavy commercial launch vehicles like our private company must be launched at the regular launch center and sent to the launch center.
In other words, we can only launch light rockets here, and we need to apply to the aerospace authorities one month in advance. "
Wu Hao nodded and then asked: "Is there any problem or difficulty?"
Yu Chengwu smiled and shook his head bitterly, "If you can't talk about difficulties, it's more troublesome.
First of all, because of the limited tunnels, the diameter of rockets that can be transported is actually limited. This is also one of the problems that restricts the launch of large rockets inland in our country.
It is also because of this that our country will decide to establish a launch center in the South China Sea to ship large rockets through the port. "
