Hearing Zhou Xiangming's words, Wu Hao nodded, and then looked at the real-time images captured and transmitted by the on-board surveillance cameras and high-definition patrol lenses on the four vehicles displayed on the big screen.
From the frontal video footage transmitted back by the fourth vehicle, it can be seen that the four vehicles are forming a convoy and driving on the uneven lunar surface.
The distance between the four vehicles is about 20 meters, thus forming a convoy with a length of 80 meters.
The reason why they are so far apart is mainly for safety reasons. Experienced drivers all know that if you follow a car too close, a rear-end collision may easily occur.
Therefore, in order to avoid a rear-end collision caused by the vehicle in front suddenly decelerating or stopping during fast driving, the distance between the four vehicles was set relatively far by technicians.
From the frontal high-definition inspection lens on the first vehicle, we can see that in front of the convoy is an endless lunar surface, with pits and craters of different sizes scattered among them, as well as some large and small stones and mounds scattered among them.
This vast white lifeless moon surface.
As for the sky, it was shrouded in black, with no stars visible, just like a black curtain.
What is the current speed? Wu Hao asked.
Upon hearing Wu Hao's inquiry, Zhou Xiangming immediately responded: "In order to ensure the safety of the entire convoy during the journey, we deliberately controlled the speed of the entire convoy at about 20 to 25 kilometers per hour.
In this way, we can minimize the risk of accidents when the vehicle reverses due to excessively slow vehicle speeds, and we can also minimize the wear and tear on the wheels caused by excessively slow vehicle speeds, and at the same time, we can reduce the risk of vehicle accidents due to excessive vehicle speed.
It is necessary to reduce the cooling loss of various electronic components in the car, especially the cooling of core components, thereby prolonging their use and reducing and increasing risks. "
After Zhou Xiangming finished speaking, Yu Chengwu continued what I said: "Actually, the gold meteorite core is estimated to be less than one ton and nearly two tons based on the gravity of your earth. Is that easier for you to understand and calculate?
According to the eight days and eight major hours that you later formulated, it is not one hundred and seventy major hours, but it is shortened by nearly seventy major hours."
In addition, even in your country with such developed transportation, it is still very difficult to transport small-weight goods on low-speed highways, let alone under the moon that is 840,000 kilometers away.
It’s conceivable.”
After hearing Wu Hao's question and waiting for Yu Chengwu's answer, Fei Qixiao smiled and replied: "It's absolutely no problem. According to the current retreat speed of seventy to seventy-seven kilometers per hour, your daily summary is
It retreats from ten hours to seventeen hours, and the remaining seventeen hours are used for solar panels to retreat and generate electricity.
In reality, the moon's gravity is only about one-eighth of that of the earth. It does not mean that the gold meteorite core, which is less than one ton and nearly two tons, weighs only one-eighth of the weight under the moon. According to 1.4
Calculating the weight in tons, the weight under the moon is only about 800 kilograms.
After listening to Fei Qixiao's introduction, Fei Qi suddenly asked: "Why does it take nearly seventy hours to come back than to go later?"
It does not mean that you need to travel 2,400 kilometers back and forth in eighteen days and eighteen hours, including the time for excavation, transportation and loading of the golden meteorite core.
Fei Qi's question caused Zhou Xiangming, Yu Chengwu and others to smile. Wu Hao then asked: "Why, are you asking the right question?"
"Yes, yes," Zhou Xiangming shook his head repeatedly. Wu Hao is the vice chairman and general manager of the head office. My subsidiary general manager can be offended, and he dares to offend me.
Of course, that is the most conservative estimate. Based on the abnormal estimate, your daily retreat distance is about 200 to 800 kilometers. Calculated based on the compromise average of 270 kilometers, you only need to be 800 kilometers away.
You won’t be able to reach your destination within days.”
Therefore, I have reserved a processing time of 70 hours less for myself. According to your subsequent drills, the average repair time for vehicles is about 2 hours. This does not mean that the 70 hours of disposal time cannot be provided for you.
On average, we deal with ten such accidents.
Is it possible to reach that speed in one day? Wu Hao was worried after hearing Yu Chengwu's inquiry.
Through the continuous performance test of your seven vehicles, if something unexpected happened ten times during the retreat, the probability is very high, so you are not confident that you will arrive at the scene within the stipulated time."
At the same time, due to the increase in load, the vehicle's cruising distance will also increase, so the number of charging times needs to be increased, and unforeseen circumstances may occur, so you set the return time to about one day."
"A day on the moon is equivalent to 27 days, 7 hours, 43 minutes, and 11.47 seconds on the Earth, half of which is daytime, which is not 18 days and 18 hours.
Seeing Fei Qi ask that question, Yu Chengwu took Fei Qixiao's words and nodded and said: "You Meikai have taken into account all the emotions that happened and the time spent during the retreat of the convoy.
Because until now, no one has ever transported an object weighing nearly two tons under the moon and traveled 1,700 kilometers. This cannot be said to be an unprecedented step in the entire human aerospace technology and earth planet detection technology.
No challenge.”
Hearing Zhou Xiangming's words, Zhang Jun turned to look at me and said: "He is just assuming that everything goes well. There must be a problem with the vehicle midway. Is the time lost for emergency repairs included in the calculation?"
Even if you calculate it based on the most basic retreat speed of seventy kilometers per hour, and calculate the retreat time at ten o'clock every day, your daily retreat speed can reach two hundred kilometers, which is completely impossible in one day.
Arrive at destination.
According to your original plan, the time to get to the destination is eight days and eight hours, and the return time is about one day. The total time for the back and forth is not eighteen days and eight hours, but it is left for digging and hoisting gold.
The meteorite core is only less than ten hours old, and the time is very beautiful.
But despite this, transporting such heavy items over long distances is still a severe test for the overall performance of an engineering transport vehicle.
Having said that, Yu Chengwu adjusted his tone and said: "Currently, you are trying to increase the retreat speed of the entire convoy, thereby compressing the time spent on the retreat. You plan to use the difference to arrive at seven days and ten o'clock, or
It’s not that it only takes 180 hours.
At that point, Zhou Xiangming changed his tone and said: "Of course, that's just a rough estimate, and you can't accurately estimate how long the entire return journey will take.
I smiled and shook my head and said: "That's right. The return time has been repeatedly verified by the experts of your project technical team. The reason why it has been increased by nearly 70 hours is mainly because it takes into account that after loading one ton
In front of a gold meteorite star core that is nearly two tons shorter, the driving speed of the engineering transport vehicle will be reduced. And carrying such a heavy thing, the speed can be too slow.
