At the Nanhai Launch Site in early July, the weather became much cooler due to a heavy rain that lasted for more than half a month.
Early in the morning, Zhou Xiangming and Yu Chengwu had breakfast, and then arrived at the vertical assembly house early.
Today is the day when the Jianmu-9 heavy-lift launch vehicle and lunar cargo spacecraft combination will be transferred to the launch tower, so whether it is Yu Chengwu, Zhou Xiangming and other technical experts representing rockets and spacecraft, or the technical team of the Nanhai launch site, they also attach great importance to it.
.
After having breakfast early, we started to get busy at the station.
To transfer this giant, which is more than 70 meters high and has a take-off mass of more than 1,000 tons, the entire process must be extremely careful. Any problems in the details will affect the combination of the Jianmu-9 and the lunar cargo spacecraft.
body safety and subsequent launch safety.
Therefore, during the transfer, there are strict requirements for the surrounding environment, temperature, wind speed, humidity, and even ground vibration. For example, on the day of rocket transfer, no heavy machinery is allowed to operate within a certain distance around it. Some large-scale
All projects must be shut down.
The purpose is to prevent ground vibrations from being transmitted during these large-scale engineering operations, thus affecting the safety of the entire transfer process and even the safety of the entire rocket and spacecraft assembly.
Of course, this will not happen under normal circumstances. On the one hand, it is because the launch site is huge enough and the construction sites are far enough away from here to prevent them from being transmitted.
In addition to ground vibration, temperature, humidity, and wind speed, especially wind speed, are very important to the entire transfer process. If the wind speed is too high, it will directly affect the safety of the rocket during transfer.
Although the transfer platform at the Nanhai launch site has a stable support tower that fixes the rocket body, it can withstand sudden strong winds to a certain extent.
However, the overall volume and mass of the Jianmu-9 rocket transported to the Jianmu-9 rocket is too large, so for safety reasons, there are very strict requirements on the wind speed on the day of transfer to avoid accidents.
The entire vertical assembly plant is about three kilometers away from the launch tower. Even though it is only three thousand meters, it took more than three hours to move. This is equivalent to traveling only about one thousand meters per hour.
Such a slow speed is equivalent to a turtle crawling, but considering that this is a transfer launch platform of nearly 2,000 tons carrying a launch vehicle and assembly with a take-off mass of more than 1,000 tons, then this speed is already fast enough.
.
Seeing the entire transfer platform carrying the Jianmu-9 and the lunar cargo spacecraft assembly slowly advancing, Yu Chengwu and Zhou Xiangming, who were following the crowd behind, breathed a sigh of relief.
The combination of Jianmu-9 and the lunar cargo spacecraft is being assembled vertically. It has been prepared and tested in the test factory of the Nanhai launch site for more than a month. It has been tested for more than half a month after being hoisted in the vertical assembly factory. Today,
This rocket is pushing the lunar cargo spacecraft assembly, and it is like a young lady who has come out of the palace, finally revealing its mysterious veil.
In fact, this is also the first time that people across the country and even the world have seen the entire Jianmu-9 and lunar cargo spacecraft combination through live broadcast channels.
The entire vertical transfer process was not only broadcast live online on the aerospace system website, the official website of Haoyu Technology and related network channels, but also the official media conducted a special live broadcast report to report the entire transfer process live.
The entire Jianmu-9 rocket is white in color and has an overall length of 75 meters. It is very tall and majestic. The top is a long fairing. The entire fairing is very huge, about 289 meters, and the diameter is more than ten meters.
.So it looks very thick and very long.
There are two connected flags on the fairing. The first and most eye-catching one is of course the conspicuous red flag, which represents the country to which the rocket belongs. Connected to the red flag is a blue flag, with the flag directly above it.
It is the white logo of Haoyu Aerospace. Under the two flags, there is a string of English abbreviations of the country and Haoyu Aerospace.
Next is the core second-stage rocket of the entire Jianmu rocket. The entire core second-stage rocket is shorter than the first-stage rocket, and the overall length is only about half of the length of the core first-stage rocket.
The most eye-catching thing on the core two-stage rocket is the four large characters of Haoyu Aerospace in dark blue. The entire font is relatively square and follows the font and color scheme of the aerospace system, making it very upright and generous.
These four words represent an identity, as well as an external image and performance of strength. You must know that there are few heavy-lift launch vehicles like this in the world. Among the heavy-duty launch vehicles in active service, Jianmu
The overall carrying capacity of No. 9 ranks among the top.
In the private aerospace field, there are only so many rockets of this level that you can count them without using your hands.
As for worldwide, this is definitely a leading presence in the field of human aerospace technology. It can basically kill 99% of the countries and aerospace companies in the world in an instant.
Not to mention, this time, the rocket fairing is carrying a global lunar cargo spacecraft for the United States, which will transport 20 tons of equipment and materials to the world's first lunar commercial scientific research station. This is even more unprecedented.
Several unique ones.
Therefore, the name Haoyu Aerospace is shining enough, and it is enough to make the entire Haoyu Aerospace, Haoyu Technology, and even the Chinese people proud.
Just a domestic private aerospace company has accomplished something that 99% of the world's countries have not accomplished. Isn't this something to be proud of?
Under the core two-stage rocket, there is the most eye-catching core first-stage rocket, and two boosters the same size as the core first-stage rocket.
In fact, both the core first-stage rocket and the two boosters are the core first-stage rocket of the Jianmu-7 rocket. This time, the two boosters are both first-stage rockets that have completed several launch missions.
Rocket.
It was slightly modified by Zhou Xiangming and others, and an arrow cap was added to the top to reduce wind resistance, and it was tied to the Jianmu-9 launch vehicle.
The same is true for this core-stage rocket. It is also a core-stage rocket, but this rocket is a brand new rocket and has not performed a launch mission.
Therefore, this has also led to a big difference between the external coating of the core first stage of the Jianmu-9 launch vehicle and the coating of the two boosters. Although for this mission and for publicity, the two boosters
The core first-stage rocket used in the thruster was repainted after maintenance and repairs. However, it may be because it burned too much in the previous launches, so even after repainting, the color was dark.
As for the brand new core first-stage rocket, the external color painting is particularly new and clean, so there is such a difference.
