Facing Wu Hao's tough tone, Zhou Xiangming opened his mouth. He tried to explain out loud, but after seeing Wu Hao's determined eyes, he swallowed back all his words.
We will do our best. Zhou Xiangming said.
Wu Hao nodded slightly when he heard this, with a smile on his face. What he wanted was Zhou Xiangming's attitude. As for whether it could be completed within two years, he didn't necessarily insist on it. He knew very well that for such a huge project, it would take almost two years to complete it.
It's impossible, but aren't humans constantly creating miracles? Haoyu Technology is a group of companies that are good at creating, so Wu Hao also hopes that through this kind of pressure, they can work hard to act. Time waits for no man.
What about the lunar lander? How is the progress in this regard? Wu Hao then turned to Zhou Xiangming and asked.
Hearing Wu Hao change the topic, Zhou Xiangming breathed a sigh of relief, but he became worried again, and then he shook his head at Wu Hao and said.
Regarding the lunar lander, our progress is not going well.
Wu Hao was not surprised by Zhou Xiangming's answer, nor did he get angry. Instead, he nodded slightly and looked at the other person and said, "Tell me, what problem did you encounter?"
Seeing Wu Hao's reaction, Zhou Xiangming secretly breathed a sigh of relief, and then said to Wu Hao and the others: "If it was just an ordinary one-time lunar lander, we should have no problem in this regard.
The sky crane technology used by our "Wangshu" intelligent lunar surface patrol and exploration vehicle can also be regarded as a lunar lander to a certain extent. Therefore, in this regard, we still have a technical foundation.
If it were just a simple moon landing, then our technology would be ready-made and could be used for reference, redesign, and application without any problems.
But our ship is capable of carrying people to the moon and transporting supplies and equipment.
Let’s not talk about the transportation of supplies and equipment, let’s talk about the manned moon landing. We must consider how to safely land people on the moon, and how to pick up people from the moon.
Docking with our Earth-to-Moon transfer spacecraft.
And this time, this is the problem we are facing now.
As we all know, the traditional lunar lander is divided into two parts, namely the lunar lander and the lunar ascender mounted on it. The lunar lander is called the manned module on the ascender, and then completes the lunar landing.
spacecraft landing on the moon.
When the lunar landing scientific research mission is completed and it is time to return, the personnel return to the lunar ascender, and then the ascender detaches from the lunar lander platform and ascends alone to the orbiter orbiting the moon, which is our Earth-moon transfer spacecraft.
Make the connection.
The personnel were transferred to the Earth-Moon transfer spacecraft, while the ascender was abandoned directly.
This is currently the most mainstream method of landing on the moon. This method was used by the old Apollo lunar landing forty or fifty years ago. This method is also used by our lunar scientific research sampling return project.
The reason why this technology has become the mainstream in lunar exploration projects in various countries is that it is the most feasible method among the current lunar landing and return technology solutions.
In a sense, the lunar lander can also be regarded as a manned spacecraft. It is divided into three parts. From bottom to top, they are the lunar lander platform, the ascender, and the carrier on the ascender.
Human cabin.
However, under normal circumstances, the ascender and the manned cabin are integrated and designed together, which can greatly reduce the structure, weight and volume. Similarly, during the return and ascent stage, only the ascender returns. This design also reduces the risk from
The mass launched on the moon can reduce the load, save fuel, and thus reduce costs.
Each unit performs its own duties and works together to complete the entire lunar landing and return steps."
Speaking of this, Zhou Xiangming slid the transparent folding tablet a few times, then put the picture on a screen in front of them and said to everyone.
“What we have to do now is to abandon this set of very mature and time-tested successful design solutions and find another way, which can even be said to overthrow all previous successful cases.
Our goal is to design and manufacture a reusable lunar landing and return vehicle. In other words, we have to abandon the previous split structure and combine the lunar lander platform and the return vehicle manned module.
It all comes together to design a lunar lander that travels to and from the lunar surface and into lunar orbit."
After saying this, Zhou Xiangming changed to a picture of the surface of the moon, and then continued to introduce to everyone: "Look, everyone, this is the moon. It is about 380,000 kilometers away from our earth and is a natural satellite of the earth.
, is the planet closest to us.
Its average radius is about 1737.10 kilometers, which is only equivalent to 0.273 times the radius of the Earth; its mass is close to 7.342x1022 kilograms, which is only equivalent to 0.0123 times the Earth's radius.
Although it looks small compared to the Earth, it is actually the fifth largest satellite in the solar system.
Because of its proximity, it has always played a vital role in our human culture. It is even given very beautiful stories in some myths. In Chinese, it is commonly known as the moon or the moon.
, Taiyin, Xuantu, Chanjuan, Jade Plate, Golden Toad, etc.
Because the volume and mass are too small, the moon's gravity is very small, so it has no atmosphere, or its atmosphere is very thin and can be ignored.
Therefore, when we land on the moon, we cannot use the same method of landing on the earth, using parachutes to decelerate and land. Therefore, rocket reverse thrust technology is generally used to continuously decelerate the lander and finally land on the moon.
It is also easier to rise above the moon because its gravity is very small, so it is relatively easy to get rid of the moon's gravity and lift off.
Note that what I said here is relatively easy. But in fact, it is also very difficult to lift off the moon.
So how to design a lunar lander that can be reused and returned is a question we have been thinking about for a long time. In this regard, we have done a lot of research and homework, and have designed many plans.
But the difficulty now is that we cannot conduct experiments with our design plans and some technologies and ideas, and intelligently use supercomputers to conduct simulations.
But you also know that the real environment is always much more complex than what is simulated in the computer, so computer simulation alone cannot fully verify our ideas and technologies.
This is also our biggest headache at present. Although we have also asked the aerospace department for help and cooperation in this area, the relevant help and support we can obtain is also very limited. We can refer to very few, so everything
