Military Technology

What Wu Hao said really aroused the fighting spirit of everyone present, and let everyone 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 board on the wall, Wu Hao couldn't help saying: "It's less than thirty hours until 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 whole region, there will be a launch window from 18:00 to 20:00 tomorrow evening, and we plan to choose an opportunity to launch during this period.

If the launch is delayed, it may be a few days later. "

Wu Hao nodded when he heard the words, then looked at the rocket monitoring screen in the middle of the big screen and asked, "What's the situation with the rocket now, are you ready?"

Zhou Xiangming nodded and replied, "Because we use a new type of semi-solid foam propellant developed by ourselves, this fuel is easier to store than conventional liquid rocket fuel, so the fuel has been filled as early as three days ago.

Moreover, we have conducted two systematic tests and two launch drills, and are now conducting the third systematic test and launch drills.

It is expected to be completed in the evening and can be transferred to the launch program. "

Yu Chengwu added: "We have already gone to the area where the rocket wreckage may fall together with the local government, to do ideological work for the people, and to evacuate during the launch. In addition, we also installed a Beidou locator on the rocket, which can track it in real time The specific location where the rocket wreckage fell, so that it can be disposed of on the spot as soon as possible.

In addition, we also cooperated with the satellite measurement and control center in Anxi and Daocheng, and they tracked and monitored the flight trajectories of rockets and satellites, and sent them to me in real time.

At the same time, the launch and the tracking and monitoring data 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: "Representatives from the developers of the three satellites have come, and they are undergoing the final commissioning of the satellites these days. Would you like to meet?"

Wu Hao shook his head with a smile and said: "Forget it, there is no need to make special arrangements. You should be able to meet it when watching the launch tomorrow.

It's time to say hello. "

Hearing what Wu Hao said, Yu Chengwu also nodded and stopped talking.

After chatting for a while, Zou Xiaodong immediately proposed to visit the rocket launch site, and this also aroused the interest of other casual people.

It stands to reason that after the rocket fuel filling is completed, other idlers are not allowed to approach. However, they use a new type of semi-solid foam propellant, which is relatively reliable in terms of safety.

So Yu Chengwu immediately agreed to their request, and then everyone got on several 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 that had been rising and falling before have been bulldozed. So from a long distance, you can see the launch tower of the launch site and the white and blue rockets erected on the tower.

Although the rocket was less than thirty meters long, the closer it got, the more shocked everyone was by his majestic body. It is hard 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 of human beings flying into space in the future will be absolutely huge, which is why the price of rocket launch loads is so expensive.

Arriving at the launch site, after putting on their safety helmets, everyone was finally able to look up at the launch vehicle that had been erected on the launch platform and was about to be launched.

Looking at the rocket, Yu Chengwu, including Wu Hao, couldn't help but soften their eyes. That feeling is like looking at your own child, and it's still a 'promising child'.

"This rocket was assembled horizontally in the final assembly and test plant at the base, and we conducted the first test. 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 The launch site, then erected on the launch platform.

Compared with the vertical assembly, vertical transfer, and horizontal assembly and transfer adopted in our country, the technical difficulty and requirements will be much lower, and the corresponding cost will be much lower.

Of course, the whole transfer process is actually very complicated. For example, the hardened road we walked on just now was specially paved with great effort.

Don't underestimate this road, the construction difficulty is very high, and its construction cost is enough to lay two airport runways. "

Yu Chengwu saw everyone's surprised and affectionate smile and said: "That's right, the cost is huge. Because this road must not only be straight, but also as flat as possible. We control the level difference of the entire road to five millimeters. A pretty high standard.

That is to say, from that end of the road to this section, the drop is less than half a centimeter.

Secondly, it is required that this road has super high anti-subsidence and anti-compression and anti-load capabilities. Dozens of hundreds of tons of rockets have to pass by, and there are very strict requirements on the road and the foundation below the road.

This may be nothing in the interior, but this is a desert, with sand underneath, and it is very easy to sink. Therefore, when building roads, we have to lay pile foundations first, and then build roads on the pile foundations, which is equivalent to building a bridge with super high standards.

Finally, it is the carrier vehicle of this rocket. We have introduced the world's most advanced self-propelled modular transport vehicle. This car not only has a heavy load, but also can be modularly assembled according to needs, and the length can be increased arbitrarily.

This also means that we can transfer longer and heavier rockets in the future. "

Speaking of this, Yu Chengwu smiled awkwardly and said: "However, according to the latest regulations of the aerospace authority, the medium and heavy commercial launch vehicles of our private companies must be launched at the regular launch center and handed over to the launch center.

In other words, we can only launch light rockets here in the future, and we need to apply to the aerospace authority one month in advance. "

Wu Hao nodded upon hearing this, and then asked, "Are there any problems or difficulties?"

Yu Chengwu smiled wryly and shook his head, "It's not difficult, but it's more troublesome.

First of all, because the tunnel is limited, the diameter of the rocket that can be transported is actually limited. This is also one of the problems that restrict the launch of large rockets in our country.

It is also because of this that our country decided to establish a launch center in the South China Sea and ship large rockets through the port. "
