What Wu Hao said really aroused the fighting spirit of everyone present, and also allowed everyone to see Wu Hao's huge space program.
Everyone couldn't help but get excited at the thought of being lucky enough to participate in this project.
Looking at the countdown sign on the wall, Wu Hao couldn't help but say: "Less than thirty hours until launch."
Yu Chengwu nodded and said: "
According to meteorological satellite cloud images and comprehensive current weather data across the country and the entire region, there will be a launch window from 18 to 20 o'clock tomorrow evening, and we plan to choose an opportunity to launch during this period.
If the launch is delayed, it may take a few days."
Wu Hao nodded when he heard this, then looked at the Rockets monitoring screen in the middle of the big screen and said, "Are the Rockets ready for whatever happens now?"
Zhou Xiangming nodded in response: "Because we use a new type of semi-solid foam propulsion fuel developed by ourselves, this fuel is more convenient to store than conventional liquid rocket fuel, so the fuel has been filled three days ago.
Moreover, we have conducted two systematic tests and two launch drills, and are now undergoing the third systematic test and launch drill.
It is expected to be completed in the evening and can be transferred to the launch procedure."
Yu Chengwu added: "We have worked with local authorities to go to areas where rocket debris may fall, do ideological work for the people, and conduct evacuation during launch. In addition, we have also installed a Beidou locator on the rocket, which can track it in real time.
The specific location where the rocket debris fell, so that we can deal with it as soon as possible.
In addition, we also cooperate with the satellite measurement and control centers in Anxi and Daocheng. They track and monitor the flight trajectories of rockets and satellites and transmit them to me in real time.
At the same time, the tracking and monitoring data of this launch and the two satellite measurement and control centers will be uploaded to the Beijing Aerospace Flight Control Center, which will conduct 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: "Representatives from the developers of the three satellites have arrived. They are undergoing final debugging of the satellites these days. Do you want to meet them?"
Wu Hao smiled and shook his head and said: "Forget it, there is no need to make special arrangements. We should be able to bump into each other when we watch the launch tomorrow. Just say hello then."
Hearing what Wu Hao said, Yu Chengwu also nodded and stopped talking.
After chatting for a while, Zou Xiaodong immediately suggested that he wanted to visit the rocket launch site, which involuntarily aroused the interest of other casual people.
It stands to reason that after the rocket fuel filling is completed, no other idle personnel are allowed to approach. However, they use a new type of semi-solid foam propulsion fuel, which is relatively safe in terms of safety.
So Yu Chengwu immediately agreed to their request, and then everyone got on several open-top 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 previously rolling sand dunes have been flattened. Therefore, you can see the launch site's launch tower from a distance, as well as the white and blue tower erected on the tower.
Alternate rockets.
Although the rocket was only less than thirty meters, the closer they got, the more people were shocked by his majestic body. It was hard to imagine that such a large rocket could only transport less than three tons of items to low-Earth orbit. It was unbelievable.
Needless to say, the money and resources consumed by humans to fly into space in the future will definitely be huge, which is why rocket launch loads are so expensive.
After arriving at the launch site, after putting on their safety helmets, everyone was finally able to look up at the launch vehicle up close, which had been erected on the launch platform and was about to be launched.
Looking at the rocket, Yu Chengwu and Wu Hao's eyes couldn't help but soften. It felt like looking at their own child, and he was also a 'promising child'.
"This rocket was assembled horizontally in the final assembly and testing plant at the base and was tested for the first time. After the test is completed, it will be handed over to our transport vehicles to transport the rocket through the hardened roads of our base and launch site to
launch site and then erected on the launch platform.
Compared with the vertical assembly and vertical transfer used in our country, the technical difficulty and requirements of horizontal assembly and transfer are much lower, and the corresponding costs are much lower.
Of course, the entire transfer process is actually very complicated. For example, the hardened road we just walked on was specially paved by us with great effort.
Don’t underestimate this road. The construction is very difficult and the construction cost is enough to pave two airport runways.”
Yu Chengwu saw everyone's surprise and affectionate smile and said: "Yes, it costs a lot. Because this road must not only be straight, but also as smooth as possible. We control the horizontal gap of the entire road to five millimeters. This is
A pretty high standard.
In other words, the gap from that end of the road to this section is less than half a centimeter.
Secondly, this road is required to have ultra-high resistance to subsidence, pressure and load. Rockets of dozens and hundreds of tons have to pass over it, which imposes very strict requirements on the road and the foundation below the road.
.
This may not matter in the mainland, but this is a desert with sand underneath, which is very easy to sink. Therefore, when building roads, we must first drive pile foundations and then build roads on the pile foundations. This is equivalent to what we have done before.
It’s like building a bridge to extremely high standards.
Finally, as the rocket's carrier vehicle, we have introduced the world's most advanced self-propelled modular transport vehicle. This vehicle not only carries a heavy load, but can also be modularly assembled as needed to increase the length arbitrarily.
This means that we can transport longer and heavier rockets in the future."
Having said this, Yu Chengwu smiled awkwardly and said: "However, according to the latest regulations of the aerospace authorities, medium- and heavy-duty commercial launch vehicles like our private companies must be launched at regular launch centers and handed over to the launch centers for launch.
In other words, we can only launch light rockets here in the future, and we need to apply to the aerospace authorities one month in advance."
Wu Hao nodded when he heard this, and then asked: "Are there any questions or difficulties?"
Yu Chengwu smiled bitterly and shook his head: "I can't say it's difficult, it's just more troublesome.
First of all, because the tunnels are limited, the diameter of the rocket 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 decided to build a launch center in the South China Sea and transport large rockets through port shipping."
