"Thank you Mr. Wu for your support and understanding."
Zhou Xiangming showed a grateful expression. It is definitely a blessing in this life to have such a considerate boss.
Wu Hao waved his hand, then motioned for him to continue.
Upon seeing this, Zhou Xiangming nodded and continued: "In fact, there are still a series of problems when moving to the recovery of rocket bodies on the sea. For example, the sea is changing and the weather changes normally. How to recover the rocket body and even the fairing in such an environment? Will bring a series of troubles and problems.
In addition, the special high-salt-alkali and high-humidity environment at sea will also cause a series of problems for the launch and recovery of rocket bodies.
Time relationship, I won't repeat them.
However, compared to the advantages or advantages of moving to the South China Sea landing site, this shortcoming or shortcoming is trivial.
First of all, the first one is the dimensional advantage brought by the low-latitude launch site, which means we have more orbits and launch angle windows.
Secondly, at low latitudes, the centrifugal force brought about by the rotation of the earth can save rocket fuel and increase the rocket's capacity, which is not possible at high latitude launch sites.
Increasing the capacity of the rocket means that we can send more and heavier loads into space. The benefits that this brings are also much higher than the costs it brings.
Finally, it is the rocket wreckage and even the recovery of the rocket body.
In the past, inland, when we launched one-off conventional rockets, we had to control the first and second stage wreckage of the rocket and the fall area of ​​the fairing.
And contact these places in the landing area in advance to do a good job in the evacuation and transfer of personnel and other livestock and property in the landing area.
This work is not only very troublesome, but also very restricted, and the relevant approval process is very strict. And this will also incur an additional cost.
If there is a deviation, it will also bring a series of problems and troubles.
But if you put it at the South China Sea launch site, you don’t have to worry about this problem, because the rocket is launched either east or south, so you don’t have to worry about the rocket debris falling down and hitting something.
Of course, this is possible even if it is placed on the sea. The wreckage of the rocket fell down and hit a ship passing through the relevant area.
But this odds is too low, lower than the odds of winning the lottery.
In general, before launching the rocket, the international maritime department and related areas will be notified of the area where the rocket wreckage will be announced, so that some ships passing through this area will evade in advance.
Next, let's talk about the recovery aspect of recoverable rockets. In the past, inland areas were fixed landing sites. This also means that the landing of the rocket body must be carried out on a fixed landing field, which greatly limits the rocket's launch flight path.
And this kind of fixed landing site requires constant adjustment of the rocket body, which will waste a part of the fuel.
As for the offshore mobile landing platform, it can be arranged at the best target position we need, and can be changed at any time according to the relevant launch needs, so as to achieve an optimal landing field position.
This is something that an inland fixed landing field cannot achieve, and the benefits it brings are considerable.
Finally, in terms of policy, the South China Sea Launch Site is an international spaceport created by the space authority. Compared with other inland launch sites, it is more open here.
This also means that we will enjoy more preferential policies, convenient conditions and superior environment here.
And we can also use this platform to absorb more international orders, which will also be an important measure for us to go overseas. "
Bang bang bang...
Wu Hao took the lead in applauding, and then admiring Zhou Xiangming while applauding: "It's a good speech. It can be seen that you have done hard work in this aspect. This aspect is worthy of recognition. You all should also be more positive. Ming learning."
Having said that, Wu Hao also gave Yang Fan a special look. After Yang Fan noticed Wu Hao's gaze, he immediately avoided. He couldn't know what Wu Hao meant.
Seeing Yang Fan’s reaction, Wu Hao smiled, then took a sip from his teacup, and said to Zhou Xiangming,
Let’s talk about the rocket, let’s talk about our smart lunar rover. project.
It’s almost a year since we announced the launch time. I want to know whether the entire launch plan can proceed as scheduled. "
Upon hearing this, Zhou Xiangming nodded and said: "I am personally responsible for our smart lunar rover project.
At present, the progress of this project is generally relatively smooth, and the launch plan can basically be guaranteed as scheduled. "
What is basically guaranteed to proceed as scheduled? Wu Hao became a little unhappy. He hated such ambiguous answers most, especially when it came to work.
Faced with Wu Hao's unhappy tone, Zhou Xiangming quickly explained: "This smart lunar rover project does have some technical problems that we haven't solved yet. At present, we are increasing manpower and working overtime to overcome them.
It's just that what we are currently working on is a brand new project that has never had a precedent, without any reference, so we need to explore all of this ourselves.
According to the design, this intelligent lunar rover will be launched by Jianmu 7 rocket and enter the Earth-Moon transfer orbit.
After entering the lunar orbit, the intelligent lunar rover will choose an opportunity to land on the moon after decelerating ~EbookFREE.me~ Unlike other lunar exploration projects, this time we will use a black technology in Laomi's Mars exploration project .
That is to use sky crane technology to hang our smart lunar rover to land on the moon.
After the intelligent lunar rover successfully landed on the moon, the suspension cable of the sky crane will be quickly separated, and the sky crane will immediately fly away and fall.
Any difference or failure during this period will cause the entire project to fail.
For example, the sky crane hangs several steel cables of the intelligent lunar rover. After the intelligent lunar rover lands on the moon, if one of the several steel cables is not disconnected in time, the sky crane will directly connect the intelligent moon The rover was hung up and fell down, even being pulled and damaged.
Or, the sky crane cannot be detached normally, and directly hits the intelligent lunar rover.
For another example, if one of the thrust engines on the sky crane fails, it will also cause the entire landing mission to fail and the intelligent lunar rover will crash.
Even the descent angle posture of the sky crane and intelligent lunar rover during landing will directly determine the success or failure of this mission. "
