Chapter 351 Modification of the Lunar Rover
It is very difficult for a lunar rover to reach the moon, and it is even more difficult to run on the moon.
If you are not careful, the lunar rover will land on the moon with the lander, and then smash into pieces.
Here you can manually take a look at the Moonship 2 of the Peacock Country.
Even if the landing is successful, the lunar rover may malfunction during use.
Just like Tianxia’s original "Yutu" lunar rover, as Tianxia’s first lunar rover, its design mass reached 140 kilograms. It is a small and exquisite guy in the spacecraft, so many people also call it "little rabbit". .
At first it worked normally and completed many experimental tasks, but before entering the second lunar night dormancy, affected by the complex lunar environment, the lunar rover's mechanism control appeared abnormal.
Afterwards, its scientific research equipment can be successfully awakened and work normally, but it cannot drive the wheels forward.
The Yutu was unable to move after more than a month of operation. Speaking of this malfunction, scientists recalled that there might be two failures in the design.
One is that Tianxia Aerospace Department has knowledge of the lunar environment, but the understanding is not in place, and some designs are not reasonable.
The second is to reduce the weight, and preparations for possible fault handling measures are not in place.
Most people think that because the lunar rover needs to be light and miniaturized, it is designed to be highly integrated. There is no backup for the corresponding parts. The driving mechanism control circuit of all wheels is on the same board. It may be that the power supply of a driving circuit is short-circuited. As a result, Yutu lost its athletic ability.
According to simulation tests and speculation on the ground, due to the lightness and miniaturization, the wire is very thin. It may be that when it passed a large rock when it was walking, the skin of a wire was cut by the rock, and the wire was short-circuited with the lunar rover support. Is the greatest possibility.
Since the Yutu is on the moon, it is difficult to actually verify it and cannot be repaired, so it can only become a lesson. We will fully consider this point and take effective measures when designing similar equipment.
So there was the later Yutu 2 lunar rover.
The No. 2 bunny started working from launch and landing, and it hasn't been broken up to now. He is a real model worker.
I said before that the lunar rover was on the moon. If it broke, there was no way to repair it. That was when no one went to the moon. When humans landed on the moon, they actually repaired the rover on the moon.
At that time, Meriken sent a manned lunar rover to the moon when manned to land on the moon, which was used to transport astronauts.
This "Apollo" lunar rover has a mass of about 210 kilograms and a simple structure. The vehicle is similar to the chassis of a normal vehicle and can be folded. After unfolding, it is 3 meters long, has a wheelbase of 2.3 meters, and is 1.1 meters high. It has 4 wheels.
Each wheel is driven by an engine and powered by a battery. The tires can maintain elasticity even at a low temperature of -100°C.
The power supply uses silver-zinc-potassium hydroxide disposable batteries, which can travel at a speed of 10-12 kilometers per hour and can carry a payload of about 490 kg.
Therefore, this kind of lunar rover is one-time and cannot be charged. The farthest record is 35.89 kilometers, and if the drag racing is released, the speed will not be limited to 12 kilometers per hour. Someone has driven 17 Speed in kilometers per hour.
There are 2 side-by-side foldable seats, each with adjustable pedals and safety belts.A large mesh dish antenna is installed on the front mast of the vehicle.The astronaut controls the rover through a T-shaped manual controller located between the two seats.
There is a control and display module on the front of the handle, which displays the current speed, direction, power supply and temperature.
The Apollo 17 lunar rover, oh, is the car that was racing to 17 kilometers per hour. Its front wheel fender was knocked off by the astronauts. Due to low gravity, the fender was missing. Blocked by the obstacle, the wheel can pick up two-meter-high dust, which greatly affects the driver’s sight.
The astronauts did not have professional tools and extra fenders, and could not repair the vehicle. They could only use tape to stick the broken fender to its original position, but repaired on the moon table and the car was covered with stains. Moon dust, these moon dust will destroy the stickiness of the tape, it will fall off after a while.
Later, scientists on the ground asked the astronauts to find a few pieces of paper in the manned cabin, and then taped them into the shape of a mudguard in the manned cabin.
There was very little moon dust in the manned cabin, so the adhesive tape was very strong, and then they fixed the paper fender to the original fender with a clip to fix the astronomical telescope.
Don't tell me, it's really easy to use.
It's all about repairing a mudguard. It is reasonable to say that it is more difficult to modify a lunar rover on the moon, but in fact it is not that difficult, at least for aerospace mechanical engineers with complete equipment.
The parts are off-the-shelf and are redesigned and manufactured by the scientists of the leader according to the actual situation. Tong Anfu only needs to use special tools to install those parts.
Not only can he, but under his on-site command, the other three astronauts can also complete the installation.
The Navigator’s modification of the lunar rover is also very simple. Although the weight of the Navigator lunar rover is heavier than the previous Meriken’s manned lunar rover, the length and width are not as long, so there is no need for two-person seats. "Standing" for one person.
You are not allowed to sit, because the newly refitted driving position is behind, so in order to increase the field of vision, the astronauts are not allowed to sit down, but a standing bracket is added. There is a hook behind the bracket to hang other vehicles. Or simple car body.
The astronaut is standing behind, and the joystick is installed on hand to connect to the core control system of the lunar rover.
To install the battery pack, remove the amateur battery pack that was roughly installed by the robotic arm and replace it with a new specially made battery pack, which can allow the lunar rover to go further.
"Let's start, Mr. Tang has taught us all the steps in the fantasy space. You should still remember. If you don't understand or have a gap with your memory, you can ask me."
Aerospace mechanical engineer Tong Anfu said with a tool.
"Okay, Fu, then start." Cheng Dong said.
Because there is an example of Merrican moon landing astronauts repairing the lunar rover, the pilot prepared a portable moondust removal device for them. It has an electromagnetic field and can blow air. It can be easily attached to key equipment. The moon dust is removed, and then precise installation.
The installation went well, and it went so well that they still had time to chat.
Of course, it is not purely nonsense, the things they talk about are related to what they are doing now.
"I have the feeling that Mr. Tang, the leader, can do everything. I don’t know if it’s my illusion, but I really feel that he can do everything. Let’s talk about the precautions for survival on the moon. I feel that he has already survived on the moon. It seems like a long time."
"I think so too. If you want to talk about his technological prowess, that is what everyone knows, but he also knows things about the moon very well. It's not just the kind of scholarly understanding, but the kind of personal understanding. , It feels amazing."
"Well, maybe this is a genius, Mr. Tang will definitely stay in history in the future, just like those super celebrities we have learned in history books."
That's it. They refitted two cars in less than an hour.
Yes, two vehicles are enough for the time being. After all, there are only four of them. It is impossible for them to leave the base together and enter the permanent shadow area.
There are two cars. First, let Lin Yang and geologist Peng Zizhen bring the ice back. Cheng Dong and Ah Fu continued to modify the two cars, and then put sandbags.
If everything is in order to find the ice, their sand castle progress will not be slow. If there is danger there, and not all four people are in danger, they can still go to rescue.
After assigning the tasks, attach a simple body to the two modified cars, one with tools, and one with a sealed storage box, and then set off one after the other.
Towards a permanently dark zone.
At the same time on Earth, Meriken Space Agency has been observing the situation of the Lunar Palace base through lunar satellites.
No way, Tianxia set up a base on the moon first. They didn't understand the situation inside, they were in a hurry!
