"Thank you Mr. Wu for your support and understanding."
Zhou Xiangming showed a grateful expression. To have such a considerate boss is definitely a blessing for technical people like them.
Wu Hao waved his hand and motioned for him to continue.
Seeing this, Zhou Xiangming nodded and continued: "Actually, there are still a series of problems in moving rocket bodies to sea for recovery. For example, the sea is changeable and the weather changes normally. How to recover rocket bodies and even fairings in such an environment?
It will bring about a series of troubles and problems.
In addition, the special high-saline-alkali and high-humidity environment at sea will also bring a series of problems to the launch and recovery of rocket bodies, etc.
Due to time constraints, I won’t go into details on these.
However, compared to the advantages or benefits brought by moving to the South China Sea landing site, this little disadvantage or shortcoming is insignificant.
First of all, the first one is the dimensional advantage brought by low-latitude launch sites, which means that we have more orbit and launch angle windows.
Secondly, low latitudes can rely on the centrifugal force brought by the earth's rotation to save rocket fuel and increase rocket capacity, which is something that high-latitude launch sites cannot do.
Increasing the capacity of rockets means that we can send more and heavier payloads into space. And the benefits this brings are far higher than the costs it brings.
Finally, there is the recovery of rocket debris and even rocket bodies.
In the past, when we launched one-time conventional rockets inland, we had to control the first and second stage debris of the rocket and the fall area of the fairing.
And contact the places in these landing areas in advance to carry out the evacuation and transfer of people, other livestock and property in the landing area.
This work is not only very troublesome, but also very restrictive, and the relevant approval process is very strict. It will also incur an additional cost.
If there is a deviation, it will also bring about a series of problems and troubles.
If you place it at the Nanhai launch site, you don't have to worry about this problem, because whether the rocket is launched to the east or south, there is the sea, so you don't have to worry about the rocket debris falling down and hitting something.
Of course, even if it is placed on the sea, it is still possible. The debris of the rocket will fall down and hit a ship passing through the relevant area.
However, this chance is too low, lower than the chance of winning the lottery.
And under normal circumstances, before a rocket is launched, the international maritime authorities and relevant areas will be notified of the crash area of the rocket wreckage, so that some ships passing through this area can avoid it in advance.
Next, let’s talk about the recovery of the rocket body of the recyclable rocket. In the past, there were fixed landing sites in the inland areas. This also means that the rocket body must be landed on a fixed landing site, which is extremely difficult.
This greatly limits the launch trajectory of the rocket.
Moreover, this kind of fixed landing site requires constant adjustments of the rocket body, which will waste some fuel.
As for the maritime mobile landing platform, it can be arranged at the best target location we need, and can be changed at any time according to the relevant launch needs to achieve the optimal landing site location.
This is something that fixed landing sites inland cannot achieve, and the benefits it brings are also considerable.
Finally, in terms of policies, the Nanhai Launch Site is an international space port built by the aerospace authorities. Compared with other inland launch sites, it is more open.
This also means that we will enjoy more preferential policies, convenient conditions and superior environment here.
And we can also use this platform to attract more international orders, which will also be an important move for us to enter overseas markets."
Bang bang bang bang...
Wu Hao took the lead in applauding, and then praised Zhou Xiangming while applauding: "That's good. It can be seen that you have worked hard in this aspect. This aspect is worthy of recognition. You all should also pay more attention to
Study tomorrow."
Speaking of this, Wu Hao even glanced at Yang Fan. Yang Fan immediately dodged after noticing Wu Hao's gaze. He knew exactly what Wu Hao meant.
Seeing Yang Fan's reaction, Wu Hao smiled, then picked up the tea cup and took a sip slowly, and then said to Zhou Xiangming: "Let's stop talking about rockets. Next, let's talk about our intelligent lunar exploration rover.
project.
It’s almost only a year away from the launch time we announced. I want to know whether the entire launch plan can go ahead as scheduled.”
Zhou Xiangming nodded when he heard this and said: "I am personally responsible for our intelligent lunar exploration rover project.
At present, the progress of this project is generally relatively smooth, and the launch plan can basically be guaranteed to proceed as scheduled."
What is basically guaranteed to be carried out as scheduled? Wu Hao became a little unhappy. He hated such ambiguous answers, especially when it came to work.
Faced with Wu Hao's displeased tone, Zhou Xiangming quickly explained: "This intelligent lunar exploration rover project does still have some technical problems that we have not yet solved. We are currently increasing manpower and working overtime to overcome them.
However, what we are currently undertaking is a brand-new project that has never been done before, without any reference, so we need to explore it ourselves.
According to the design, this intelligent lunar exploration rover will be launched by the Jianmu-7 rocket and enter the Earth-moon transfer orbit.
After entering the lunar orbit, the intelligent lunar exploration rover will decelerate and then choose an opportunity to land on the moon. Unlike other lunar exploration projects, this time we will use a black technology from Laomi's Mars exploration project.
That is to use sky crane technology to hoist our intelligent lunar exploration rover to land on the moon.
After the intelligent lunar exploration rover successfully lands on the moon, the sky crane's suspension cable will quickly detach, and then the sky crane will immediately fly away and fall.
Any errors or failures during this period will cause the entire project to fail.
For example, the Sky Crane hangs several steel cables of the intelligent lunar exploration rover. After the intelligent lunar exploration rover lands on the moon, if one of these steel cables does not break away in time, the sky crane will directly lift the intelligent lunar exploration vehicle.
The rover was hoisted and fell, or even pulled and damaged.
Or, the sky crane could not detach normally and directly hit the intelligent lunar exploration rover.
For another example, if one of the thrust engines on the sky crane fails, it will cause the entire landing mission to fail and the intelligent lunar exploration rover to crash.
Even the descent angle and posture of the sky crane and the intelligent lunar exploration rover during landing will directly determine the success or failure of the mission."
