Because the convoy was going to continue to set off for training, early the next morning, Jiang Chen and others saw off the convoy. The pen fun pavilion www.biquge.info said that it was a send-off, that is, an ordinary breakfast, but the master of the kitchen specially made ramen for Jiang Chen and them today. In his words, this is the authentic Kawasai ramen, and the ramen that is used all over the country is just a branch of Kawasai ramen. The noodles are really strong, especially with the radish and beef, and they are especially delicious. In the early spring, when it is still relatively cold, it is definitely the best choice for a cold breakfast after all. Under Jiang Chen's adjustment, everyone's emotions did not seem a little lost. It's just that there is a girl in the accompanying team, and she seems to be in eye contact with a driver of the team, and the affectionate and life-threatening look makes Jiang Chen feel a little sadistic when he sees it. However, the overall atmosphere was good, but when everyone was talking and laughing, I saw Chang Qing rushing over.

Lu Lao saw Chang Qing's appearance, and then said with some dissatisfaction: "It's in a hurry, what does it look like, how like a person who does big things." ”

And Jiang Chen looked at him and said with a smile: "It's been like this for a long time, you went there, hurry up and eat it, this is authentic Hexi ramen." ”

Chang Qing didn't pay attention to Jiang Chen, but said excitedly to Lu Lao: "Teacher, there is a result over there in Nanshan." ”

Hearing this, everyone was interested, and then they all stared at Chang Qing, while Lu Lao looked at him and asked with a smile, "There is a solution." ”

"Yes. Chang Qing handed the paper in his hand to Lu Lao and said.

Lu Lao took it to his hand and looked at it, then handed it to Cui Lao on the side and said with a smile: "It's about the same as what we calculated yesterday." ”

Cui Lao and Liu Lao took their hands and looked at them for a while, and then they both smiled and said, "Okay, just have this result, so that we can recover a lot of losses." ”

And Jiang Chen, who was next to him, saw this scene and smiled: "Old Lu, it's solved?"

Lu Lao nodded and said with a smile: "It's solved, eat first, wait for this to send the team away, and then discuss it to see how we should build." ”

Well, everyone nodded, and fell into the lively atmosphere again.

After eating, the convoy began to set off. This time, Jiang Chen and Lu Lao and their group of scientific researchers will no longer follow the team, so the team side is much more concise, in addition to the original ten racing cars, the others only have five support vehicles and some accompanying support personnel. This is the member of the entire team, Jiang Chen deliberately let go this time, just to exercise their individual handling ability. The real game, Jiang Chen can't pass, so everything still needs their own ingenuity. The road from here to Grape Valley is basically a desert Gobi terrain and climate, which is very similar to the entire Dakar African schedule, so this is also the reason why Jiang Chen formulated this route.

Under the farewell of everyone, the team embarked on a long journey. As for Jiang Chen, they cleaned up a little, and then got together again. And Cui Lao saw that Jiang Chen and they were all here, and then took out the page and pointed to the drawings and introduced to everyone: "I believe everyone has heard about it when they are eating, and the comrades in Nanshan have already made a solution." According to their calculations, they calculated that we only need to change the direction angle of this runway to three degrees west, that is, from the current 53.2 degrees west of due north to 56.2 degrees west of due north. The elevation angle of the pavement (surface) is plus or minus two degrees from northwest to southeast, and this problem can be solved. This result is similar to the result of our calculations yesterday by a few old fellows, and our calculations yesterday were also around fifty-six degrees, so we think this result is correct and feasible. At present, we need to solve the problem of how to carry out the construction and renovation of the existing runway, so as to minimize the amount and time of construction, as well as the loss. ”

Mr. Liu, who is in charge of the construction of the runway of this airport, said: "If you turn three degrees, it is actually very easy to operate." We can follow the center point of the runway, rotate it three degrees, and then cut it out of the excess and make up for the missing parts, and that's fine. It's just that I don't know if the steel structure of the entire runway is vertically bundled and laid according to the runway, and the cutting and rotation of the excess part will affect the strength of the runway. ”

Lu Lao nodded and said: "This is a problem, when the plane is taxiing and taking off and landing, the impact on the airport is huge. And this design is to strengthen the strength of the airport to cope with such an impact. If you cut the whole and deviate to three degrees, there may be no problem in a short time, but I am worried that there will be no problem in the case of such a large temperature difference between day and night in the northwest for a long time. ”

And Du Lao on the side also nodded and said, "I think we should pay attention to this issue." Rather than waiting for it to have problems in the future, let's solve it in advance. You know, building a runway is much cheaper than repairing one. ”

Seeing Jiang Chen sitting there silently, but holding a notebook and calculating something. Lu Lao opened his mouth and said, "Xiao Jiang, do you have any good solutions?"

Jiang Chen put down the pen and then looked at everyone looking at him, so he smiled slightly: "I just listened to everyone's concerns, so I also calculated it." I'm a layman, so listen to it and see if my idea works?"

"Hehe, what kind of layman, don't our ancestors often say that three stinkers can top one Zhuge Liang. To be bold, it's okay to be wrong. Cui Lao said with a smile.

"That's all I have to say. In response to the plan that everyone said, I made a summary. I generally agree with the solution proposed by Mr. Liu. However, I would recommend that this runway not be cut, but rather complement what is missing after steering. And this supplementary part, the foundation must be solid, and the filling part on both sides must be used to wrap the runway. In this way, the structure of the original runway that we do not move will not reduce its own strength. The two sides, not the four sides, as well as the head and tail, are wrapped and consolidated on these four sides, so that to a large extent, the impact of the weakening of the strength caused by the change of the force angle of the reinforcement structure can be reduced. Jiang Chen swallowed his saliva and continued: "This is the first method, and there is a second method. Isn't our runway pavement not yet paved, so let's lay another layer of steel frame under this pavement. It's just that the direction of this reinforcement layer network is perpendicular to the direction of the new runway, so that the two layers of reinforcement form an angle. We weld these two layers of steel to form a single unit. In this way, the angle formed by the two layers of steel bar makes each area a small triangular structure. As you know, this triangular structure is the strongest in mechanics. So in this way, the strength of the runway does not decrease, but increases. ”
