Military Technology

After listening to Zhou Xiangming's introduction, everyone finally understood. Originally, everyone thought that it would be driven for twelve hours, and then charged for twelve hours, just like our daily routine, doing the Zhouye rotation.

But in fact this is not the case, but a three-hour alternating rotation. In this way, although each travel time is relatively short and the charging time is also relatively short, it lacks the ability to charge quickly and walk quickly to achieve the effect of a quick trot.

Moreover, during the three-hour alternating charging process, the multi-purpose engineering robot and the Wangshu No. 2 patrol test vehicle can also be used to alternately inspect and maintain the four vehicles in the entire fleet, thereby ensuring that all four vehicles are in optimal condition. This can reduce the occurrence of various failures during travel.

Now this car... Just when Wu Hao was about to speak, several beeps suddenly came from the hall, and then he heard an announcement from the radio.

"Report, Wangshu No. 2 got stuck in the car and the movement was blocked!"

Um?

After hearing the live broadcast, Wu Hao and Zhang Jun couldn't help but be filled with doubts. Was it a coincidence that they arrived, or was it deliberately shown to them by Yu Chengwu and Zhou Xiangming.

Looking at the expressions of Wu Hao and Zhang Jun, Yu Chengwu smiled at them, then turned around and said seriously: "Bring up the scene scene and start the rescue according to the relevant plans."

clear!

Immediately, several picture windows appeared on the big screen, and inside the windows were images taken by Wangshu-2 and the nearest multi-purpose engineering robot.

The picture shows that the Wangshu-2 inspection test site is slipping in a piece of lunar soil. Among the four sets of road wheels, several wheels are already spinning rapidly, digging deep ruts downwards. The sharply turning wheels are spraying towards the lunar surface. Bursts of dust came out.

However, unlike on the earth, these kicked up lunar dust fell to the ground one after another after splashing for tens of meters. It was not like the spectacular scene of flying dust on the earth.

We may have encountered a fluffy covering of lunar soil. Zhou Xiangming, standing aside, looked at the picture on the big screen and said in a deep voice.

Fluffy covering of moon soil?

Hearing this term from Zhou Xiangming's mouth, Wu Hao and Zhang Jun couldn't help but become confused.

Seeing the confused looks on the two people's faces, Zhou Xiangming immediately explained: "It's actually soft lunar soil. Due to the impact of meteorites, the hard lunar soil rocks on the moon will be broken into pieces, thus stirring up a lot of dust. The dust will follow The moon's weak gravitational pull gradually formed a very fluffy soil layer.

It's like we encountered particularly soft mounds of fine soil, volcanic ash layers, or sand on Earth.

Because the gravity on the moon is relatively small, this will cause the lunar rover to become lighter, so the weight will reduce the grip of the tires.

There is no problem in other areas, but when encountering such soft soil and sand dunes, it is easy for the car to get stuck and slip. "

What should we do now? Zhang Jun asked immediately after listening to Zhou Xiangming's explanation.

Yu Chengwu shook his head slightly and said: "Don't worry, we have made sufficient plans for this kind of situation to ensure that the vehicle can get out of trouble safely and smoothly."…

Speaking of which, the intelligent robotic arm on the Wangshu-2 patrol test site has slowly risen under the remote control of the ground controller, and began to carefully observe the situation around it, especially the wheels.

With the close observation of the high-definition gimbal lens on the top of the intelligent robotic arm, everyone could clearly see the specific situation under the car.

I can see that half of the wheels of Wangshu-2 patrolling the test site have been sunk into the lunar soil. If you look carefully, you can see that the lunar soil here is just like what Zhou Xiangming said. It is made of soft rare earths and looks very fluffy. It is expected that It is soil, rather than sand. Very fine sand looks very pure, like fine ash.

You guessed it right, we encountered the fluffy covering layer of lunar soil. Zhou Xiangming said calmly and calmly. "Increase the power output of the driving wheels and see if you can rush out!"

clear!

Immediately, as the operator issued instructions, the four sets of driving wheels of Wangshu 2 began to rotate with increased power, and the vehicle instantly lifted up a large amount of lunar soil, just like a sand blasting machine.

Try moving laterally!

clear!

As the command was issued, the Wangshu-2 patrol test vehicle began to turn and began to squirm in the soft lunar soil.

"This is not the way to go. If it doesn't work, drag it out first and find another way." Yu Chengwu glanced at Wu Hao and Zhang Jun who were watching the big screen, and then said to Zhou Xiangming.

Zhou Xiangming shook his head and said: "We still don't know how large the area of ​​this fluffy lunar soil cover is. If the area is too large, it will take a lot of time to detour.

Let’s give it a try first. This road is also the most ideal road we have planned. Logically speaking, this situation is unlikely to happen. But now that you have encountered it, let’s try it first.

I took into account that the area of ​​​​this fluffy covering was not too large, and it should be crossed quickly. "

Isn't this too risky? If all four cars are stuck, then we will really lose our wives and lose our troops, and we will cry without tears. Yu Chengwu said worriedly.

After hearing Yu Chengwu's words, Zhou Xiangming thought for a moment and then said: "Release the rope and let the other three vehicles wait where they are. If the rope is released and the vehicle in front has not passed the range of the fluffy covering, then resolutely tow it back to the detour."

After hearing this, Yu Chengwu thought for a moment, then nodded and said, "Then give it a try."

As the order was given, the winch behind the Wangshu-2 patrol test site was seen turning, drawing out a composite rope.

This is a rope made of composite materials, totaling 120 meters. The rope is very thin, only 3.2 millimeters, but very strong. It can withstand a pulling force of five tons.

The reason why such a winch rope is equipped is mainly to prevent situations like this from happening, so that the winch rope can be used to escape.

It is not only used to deal with this kind of car trap, but also can be applied to rolling, rolling over, towing, etc.

In the entire fleet, there are a total of two vehicles equipped with such a winch rope. In addition to the Wangshu No. 2 patrol test site, which is equipped with a winch at the back, the engineering transport vehicle is also equipped with such a winch at the front.

The two winches can be used in relay or at the same time. In this way, in theory, objects of more than eight tons can be pulled, and there is still a certain safety redundancy.

And these winches can be quickly disassembled and equipped on other vehicles. This means that even if the engineering transport vehicle carrying the gold meteorite core fails and completely loses power, the other three vehicles can still tow the engineering transport vehicle through the winch rope. march.
