Chapter 1148 Lunar Rover

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

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

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

At this time, Zhao Zhongyao looked at Qu Yuqian again and said: "It's man-made, maybe I will be able to realize my dream of traveling around the universe in this life." ”

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

Of course, he only thinks 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, don't laugh, let's continue to play!"

Although Zhao Zhongyao has his own thoughts in his heart. However, Qu Yuqian didn't take Zhao Zhongyao's statement as one thing at all, she just felt that what Zhao Zhongyao said was a joke, and she didn't have to take it as a thing at all.

"Let's go, 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 went out for a day. It wasn't until the evening that I returned home.

The two children were also very happy to see their father with them. From time to time, he was running around Zhao Zhongyao.

Looking at the two lovely children, Zhao Zhongyao felt a sense of happiness that he had never had. He now suddenly felt how happy his life was. In fact, what a person pursues is not fame and money. It's this kind of family fun with family and children.

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

But Zhao Zhongyao knows that there is still a lot of work to do now. This moon landing can be said to have been pressing on Zhao Zhongyao's heart. He knew that as long as this great dream came true, then he could give himself a long vacation, and then take his wife and children to play around the world.

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

The rest of the work is still very heavy. This 'Luna-1' probe, although it was successfully launched. But the next step is to launch a 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, to put it mildly, can only be regarded as a satellite. But this lunar rover probe, that's different. It's a whole new thing. It's something that Zhao Zhongyao hasn't developed before.

Regarding the matter of this lunar rover, Zhao Zhongyao is in this world, which is something that he has never heard of. In this world, every scientific research conducted by Zhao Zhongyao can be said to be something unique.

After all, the moon landing program 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 project. Even country M, which has always been the most developed, has no such plans.

What China can do is to complete their 'manned space experiment' as soon as possible. Although it was a failure once, at the expense of an astronaut. But country M still hasn't given up on their dream of sending astronauts into space.

But no matter what. Huaguo has long sent astronauts into space. Such a thing as a 'manned space experiment' has long been completed.

And what China wants to do now is to send astronauts to the moon on behalf of all mankind. At that time, Huaguo will also become the only superpower in the world. No other country can compare with China.

Even 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 complete the great dream of landing on the moon. Then let China become the only superpower in the world.

But to realize this great dream of landing on the moon, it is necessary to first develop a lunar rover probe. As long as the lunar rover probe is developed first. Let's simulate a spacecraft launch to the moon first.

After Zhao Zhongyao returned to the 'Feitian Group'. I hurriedly convened a mobilization meeting first. Now all the scientific researchers of his 'Feitian Group' have gathered in the conference room of the 'Space Technology Research Institute'.

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

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

The next step is to launch the rover probe to the surface of the moon. 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's just that you can take some pictures of the topography of the lunar surface in the sky above the moon. And you can't do a field survey of the earth.

If we want to send astronauts to the moon, the first thing we need to do is to do a field trip to the moon. The only way to conduct a field trip to the moon is to launch a rover probe to the moon.

Therefore, our next main task is to develop a lunar rover probe. That's where we focus next. 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 rover probe, it will be very important for the astronaut landing experiment that we will carry out next.

If we want to experiment with this great lunar landing program, 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 else. After the meeting is adjourned, let's all go to work!"

After Zhao Zhongyao held a mobilization meeting for everyone, he asked everyone to go to work. And he was back in his office.

What Zhao Zhongyao has to 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 wanted to design a lunar rover, he would have to look for a lunar rover from his memories before his death.

A lunar rover is a specialized vehicle that can travel on the lunar surface and complete complex tasks such as lunar exploration, investigation, collection and analysis of samples. In order to make the lunar rover run smoothly on the lunar surface, the United States and the former Soviet Union have launched a series of satellite explorations and carried out repeated scientific experiments on the lunar environment, laying a reliable foundation for the success of carrying the lunar rover on the lunar surface. Scientists have analyzed and studied the valuable data brought back from the field trip to the lunar surface of the lunar rover, which has greatly deepened mankind's understanding of the moon.

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

The rover chassis is made of aluminum tubular material and has a hinge in the middle to facilitate the storage of items. Each aluminum wheel has its own electric drive and mechanical brakes. The tires are made of braided steel mesh coated with a zinc layer. All the lunar rovers ended up on the moon.

Zhao Zhongyao also has a good understanding of the types and functions of the lunar rover in the world when he was alive. After all, in the world before Zhao Zhongyao's death. The level of science and technology of mankind is quite developed.

There are already many countries that have completed such great programs as the moon landing. Dozens of astronauts have successfully landed on the moon. Footprints of human activity were 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 would not be easy for him to design a real lunar rover. After all, he hadn't done it before, and even before his death, he hadn't designed a lunar rover.

But Zhao Zhongyao knows that in this world, he is the best scientist who represents all mankind. What others can do, he can certainly do. What others can't do, he can do.

Therefore, Zhao Zhongyao firmly believes that he can design a lunar rover. Although this task is somewhat difficult. But Zhao Zhongyao's heart is full of strength, and he knows 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 them develop it, so that the real lunar rover can be developed.

Therefore, when Zhao Zhongyao really wanted to do this, he had to seriously think about the functions of some specific systems of the lunar rover. In a sense, the lunar rover belongs to robotics.

The lunar rover, whether wheeled or legged, should have basic functions such as forward, backward, turning, climbing, fetching, sampling, and flipping (the ability to roll over after falling), and even have rudimentary artificial intelligence (e.g., identifying, climbing, or bypassing obstacles, etc.). These are all similar to the functions that modern robots have. However, these features are not enough for the lunar rover.

It is a kind of robot that performs exploration tasks in the special environment of space - space robot, which has the attributes of a robot and the characteristics of a spacecraft, which is different from industrial robots, medical robots and household robots used on the ground. "Light weight, small size, low power consumption" has always been the golden rule of spacecraft design, and it is called "conventional three" in the evaluation index of recent aerospace superior products; The pursuit of "light, small and low" is the eternal theme of spacecraft research and development.

The longer the voyage and the higher the requirements, the lighter, smaller and lower the mass, size and power consumption requirements for the lunar probe. According to the capabilities that China's launch vehicles can expect to achieve, one lunar rover needs to be launched by a launch vehicle 300 times heavier than it, which is 4~6 times the mass of a launch vehicle launching an Earth satellite of the same mass.

The rover is a movable platform that carries several payloads, such as probes or excavation samplers. These devices and devices must be miniaturized and lightweight. The rover is usually used as a payload for a lunar orbiter, which in turn is mounted as a payload for a launch vehicle in a narrowly diameter fairing at the tip of the rocket.

The rover should be made foldable in order to reduce the launch volume as much as possible. The power supply of the lunar rover is not easy to come by, and the area and mass of the solar cell to generate electricity are proportional to the power consumption; In the case of disposable batteries, the mass is proportional to the time of use, and in order to reduce the mass, the power consumption must also be reduced. Therefore, the design of the lunar rover must fully use microelectronic devices, micromechanics and lightweight materials, and a breakthrough should be made in the development and application of microelectromechanical systems in the lunar rover.

When the mission is officially accepted, the lunar exploration project will generally put forward the index requirements for the mass, size and power consumption of the lunar rover. The lunar rover should be developed in accordance with the specified technical indicators. According to what the chief scientist has learned, the mass of the prototype of the lunar rover that has been made is many times higher than the envisaged indicators, and 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; Shocks, overloads and possibly multiple bounces and rolls from landing with airbags during the landing of the braking rocket. The lunar rover must withstand these "falls, hits, rolls, climbs" and other tosses.
