Chapter 1148 Lunar Rover

After listening to what Zhao Zhongyao said, Qu Yuqian really yearns for this kind of life traveling around the universe. It's just that she feels that this matter is too illusory. I can only imagine it now.

"Zhongyao, what you said is quite good, but we want to realize the dream of traveling around the universe. I'm afraid we won't be able to realize it in this life. Maybe we can only wait until the next life to realize it."

Although Qu Yuqian is very yearning for what Zhao Zhongyao said, she also knows that such a dream is difficult to realize.

At this time, Zhao Zhongyao looked at Qu Yuqian again and said, "It depends on human effort. Maybe I can realize my dream of traveling around the universe in this lifetime."

Zhao Zhongyao has always been a person who dares to think and do. In this world, he has done many seemingly impossible things. This dream of traveling around the world seems impossible. However, Zhao Zhongyao still wanted to give it a try.

Of course, he is just thinking about it now, and he knows that this great dream may be much more difficult than realizing a dream like landing on the moon. But no matter how difficult it is, Zhao Zhongyao still wants to give it a try.

"Okay, Zhongyao, stop joking, let's continue playing!"

Although Zhao Zhongyao had his own ideas in mind. However, Qu Yuqian would not take what Zhao Zhongyao said seriously at all. She just felt that what Zhao Zhongyao said was just a joke, and she didn't have to take it seriously at all.

"Come on, let's continue playing!" After Zhao Zhongyao finished speaking, he took his wife and children to play in the World Park again.

On this day, Zhao Zhongyao and his wife and children played outside for a day. It wasn't until late at night that he returned home.

The two children seemed very happy to see their father with them. From time to time, he ran around beside Zhao Zhongyao.

Looking at the two lovely children, Zhao Zhongyao felt a sense of happiness that he had never experienced before. He now suddenly feels how happy his life is. In fact, what a person pursues is not fame and fortune. It's the joy of being with family and children.

Look at the cheerful smiling faces of the children. Zhao Zhongyao thought, if one day, he could stay at home for a long time, and then take his wife and children outside to play every day, how great it would be!

But Zhao Zhongyao knows better that he still has a lot to do now. It can be said that this matter of landing on the moon has always been on Zhao Zhongyao's mind. He knows that as long as this great dream is realized, he can take a long vacation for himself, and then travel around the world with his wife and children.

But no matter what, Zhao Zhongyao still has to work now. After staying at home for a week, he returned to the 'Feitian Group'.

The next work is still very heavy. Although the "Lunar One" probe was launched successfully. But the next step is to launch the lunar rover probe.

This lunar rover probe is much more important than this satellite probe. Of course, it is also more difficult to develop. This satellite probe, speaking, can only be regarded as a satellite. But this lunar rover probe is different. It's a brand new thing. It is something that Zhao Zhongyao and the others have not developed before.

Zhao Zhongyao has never heard of this lunar rover thing in this world. In this world, every scientific research conducted by Zhao Zhongyao can be said to be unique.

After all, the moon landing plan that Huaguo is going to carry out now can be said to be unprecedented. In this parallel world, no country dares to carry out this great plan. Even country m, which has always been the most developed country, has no such plan.

until now. What country m can do is to quickly complete their "manned spaceflight experiment". Although it failed once, an astronaut was sacrificed. But Country M still hasn't given up their dream of sending astronauts into space.

But no matter what. China has long sent astronauts into space. Such things as "manned spaceflight experiment" have been completed long ago.

And what Huaguo wants to do now is to represent all mankind and send astronauts to the moon. At that time, Huaguo will become the only superpower in the world. No country can be compared with Hua Guo.

A technologically advanced country like country m has no dream of landing on the moon. They haven't sent astronauts into space yet, so don't try to send astronauts to the moon.

Zhao Zhongyao knew that what he had to do was to let Huaguo realize his great dream of landing on the moon. Then let Huaguo become the only superpower in the world.

But to realize this great dream of landing on the moon, we must first develop a lunar rover probe. Just develop a lunar rover probe first. In order to simulate launching a spacecraft to the moon first.

After Zhao Zhongyao returned to the'Feitian Group'. Then a mobilization meeting was held in a hurry. Now all the scientific researchers of his "Feitian Group" gathered in the meeting room of the "Space Technology Research Institute".

Zhao Zhongyao is sitting on the rostrum now, and he looked at everyone and began to speak.

"Comrades, let's sit together for a meeting today. There is only one purpose, which is to discuss how to complete the next step of aerospace work.

The next step, what we have to do is to launch the rover probe to the moon

surface. It is necessary to conduct a field survey of the surface of the moon.

Although last time, we have already launched a lunar probe. But this lunar probe is just a satellite probe. It is just to be able to take some pictures of the topography of the moon's surface in the sky above the moon. It is not possible to conduct field visits to the earth.

If we want to send astronauts to the moon, the first thing is to conduct a field trip to the moon. And to conduct on-the-spot investigations on the moon, the only way is to launch the lunar rover probe to the moon.

Therefore, our main work in the next step is to develop the lunar rover probe. This is the focus of our next work. Of course, this lunar rover probe was mainly designed by myself.

After I design it, I will let everyone work together to develop this lunar rover probe. After we develop this lunar rover probe, we can launch it. If we can successfully launch the lunar rover probe, it will be very important for our next step of astronaut landing experiments.

If we want to experiment with this great moon landing plan, we must start with the development of a high-quality lunar rover probe. As long as this lunar rover probe is developed first, we can proceed to the next step.

Well, I won't say much about other things. After the meeting is over, let's all go to work separately! "

After Zhao Zhongyao held a mobilization meeting for everyone, he asked everyone to go to work separately. And he returned to his office.

What Zhao Zhongyao will do next is of course to develop this lunar rover probe.

Regarding the development of a lunar rover, Zhao Zhongyao knew that in this world, there was nothing else to learn from. In this world, there is no such thing as a lunar rover. If he wants to design a lunar rover, he can only find a lunar rover from his memory during his lifetime as a reference.

A lunar rover is a special vehicle capable of driving on the surface of the moon and completing complex tasks such as lunar exploration, investigation, collection and analysis of samples. In the laboratory, the scientific name of this important role is "lunar surface inspection probe". In order to make the lunar rover travel smoothly on the lunar surface, the United States and the former Soviet Union have launched a series of satellites to detect and monitor the lunar environment. Repeated scientific experiments have laid a reliable foundation for the success of carrying the lunar rover on the probe. Scientists have analyzed and studied the precious data brought back by the field investigation of the lunar surface by the lunar rover, which has greatly deepened human understanding of the moon.

Lunar vehicles can be divided into unmanned lunar vehicles and manned lunar vehicles. The unmanned lunar rover consists of a wheeled chassis and an instrument cabin, powered by solar cells and batteries. The world's first unmanned lunar rover was sent to the moon by the Luna 17 probe launched by the former Soviet Union on November 17, 1970.

The lunar rover chassis is made of aluminum alloy tubular material, and is hinged in the middle to store items. Each aluminum wheel has its own electric drive and mechanical brake. The tires are made of woven steel mesh coated with a layer of zinc. All rovers were eventually left on the moon.

Zhao Zhongyao also knew quite well the types and functions of lunar rovers in the world before his death. After all, in the world that Zhao Zhongyao lived in. The technological level of human beings is quite advanced.

Many countries have already completed such great plans as landing on the moon. Dozens of astronauts have successfully landed on the moon. Footprints of human activities have been left on the moon.

But Zhao Zhongyao also knew that although he knew something about the lunar rover in the world before his death, it was not easy for him to design a real lunar rover. After all, he had never done this before, and even in his lifetime, he had never designed a lunar rover.

But Zhao Zhongyao knew that in this world, he was the best scientist representing all mankind. He can certainly do what others can do. He can do what others cannot do.

Therefore, Zhao Zhongyao firmly believes that he can design the lunar rover. Although this task is somewhat difficult. But Zhao Zhongyao's heart was full of strength, and he knew that he must develop this lunar rover.

But if you want to develop a lunar rover, you must first design the shape and internal structure of a lunar rover, and then let Cheng Yu and others develop it, so that the real lunar rover can be developed.

Therefore, when Zhao Zhongyao really wants to do this, he has to seriously think about what he knows about the functions of some specific aspects of the lunar rover. In a sense, lunar rovers belong to robotics.

Whether the lunar rover is wheeled or legged, it should have basic functions such as forward, backward, turning, climbing, fetching, sampling and turning over (turning over after falling), and even have basic artificial intelligence (for example, recognition, over or around obstacles, etc.). These are similar to the functions that modern robots have. However, these functions of the lunar rover are not enough.

It is a robot that performs detection tasks in a special environment in space—a space robot, which has both the attributes of a robot and the characteristics of a spacecraft, and is different from industrial robots, medical robots and household robots used on the ground. "Light weight, small size, and low power consumption" has always been the golden rule of spacecraft design, and it is called the "conventional three items" in the evaluation indicators of recent aerospace superior products; eternal theme.

The farther the voyage, the higher the requirements, and the lighter, smaller and lower the requirements for the mass, volume and power consumption of the lunar probe. According to the expected capability of China's launch vehicle, a lunar rover needs to be launched by a launch vehicle 300 times heavier than it, which is

4~6 times the mass of the launch vehicle launching the same mass earth satellite.

A lunar rover is a mobile platform that carries several payloads, such as detection instruments or excavation samplers. These equipment and devices must be miniaturized and lightweight. The lunar rover is usually used as the payload of the lunar orbiter, and the orbiter is used as the payload of the launch vehicle installed in the narrow diameter fairing at the top of the rocket.

The lunar rover should be made collapsible to reduce the launch volume as much as possible. The power supply of the lunar rover is hard-won. Solar cells are used to generate electricity, and its area and mass are proportional to the power consumption; if disposable batteries are used, the quality is proportional to the use time. In order to reduce the mass, power consumption must also be reduced. Therefore, the design of the lunar rover must make full use of microelectronic devices, micro-machines and light materials, and breakthroughs should be made in the development and application of MEMS lunar rover.

When officially accepting the mission, the lunar exploration project will generally put forward the index requirements for the quality, size and power consumption of the lunar rover. The lunar rover should be developed according to the specified technical indicators. According to the situation learned by the chief scientist, the quality of the prototype of the lunar rover that has been made is many times higher than the expected index, even an order of magnitude higher.

The lunar rover must adapt to the special environment of spaceflight, including the mechanical environment and the space environment. The mechanical environment refers to the shock, vibration, overload and noise generated by the launch vehicle during the launch and ascent of the lunar rover; the shock and overload generated by the braking rocket during the landing on the lunar surface, and the multiple bounces and rolls that may be caused by the use of airbags to cushion the landing. The lunar rover must withstand these "falling, hitting, rolling, climbing" and other toss.
