Chapter 115 Similar to Zulong!

Zhu Yuanzhang said this sentence is the most appropriate.

After all, he was a beggar before.

If you look at it at a glance, it seems that in that turbulent era, a beggar like him would not live long. He might just lie down and end his life hastily.

How could it be possible that he later single-handedly established the Ming Dynasty!

How could it be possible to end the turmoil at the end of the Yuan Dynasty and establish the last dynasty of the Han people?

So he is particularly qualified to say this, and when he says it, he is particularly convincing!

Fortunately, the descendants of the flower grower have perfectly inherited this fine tradition from Zhu Yuanzhang.

Yes, even if you know that this lunar rover may not be able to complete its mission.

It is possible that all the early work and hard work will be in vain, and in the end, everything will have to be started again.

However, at this moment, they still did not give up their goal!

…

[As for the landing of extraterrestrial objects, the key is to slow down.]

【People have thought of many ways to do this.】

[There are airbag bouncing solutions, aerial crane solutions, landing legs, etc.]

[Among the three options, the airbag will limit the weight of the lander.]

[The crane technology is also too complex.]

[In the end, the flower grower decided to adopt the third option, which is the landing leg solution. 】

…

Although the emperors did not understand it, they seemed to gradually understand it with the understanding in the picture.

It is equivalent to custom-making a chair for one person...

Hmm...that's all I can understand for the time being.

…

[And this plan brings many thorny problems. 】

[When landing on Aquamarine, you can use a parachute to slow down the speed.]

[But on the moon, there is no air, so the engine can only rely on reverse propulsion to achieve smooth deceleration. ]

[Among them, there is a core issue, which is to ensure that the power system can be changed. 】

[So there must be an engine with variable thrust.]

[Just like driving a car, the speed can be downshifted or upshifted at any time according to the need.]

[It can even work with continuously changing thrust within the range of 7500 N to 1500 N, under each thrust magnitude. 】

…

When the emperors saw this, they were a little dumbfounded.

Use an inappropriate metaphor.

It's as if a primary school student has entered a college student's class. It makes people a little confused as to what car gear and what 7,500 Nm.

However, everyone still tried to understand him. In short, it was too difficult!

And once it is built, it will become a national weapon!

…

[Variable thrust engine has become the first key technology to ensure soft landing.]

[But at that time, there were no ready-made variable-thrust engines among flower growers.]

[At that time, the team dedicated to solving this technical problem only had two years. 】

[After you get it done, you can get the model number, and then you can work on it in the future.]

[But once it fails, the entire Chang'e-3 mission will be blocked, and the plan will need to be changed again!]

[It can be said to have a significant impact!]

…

"Familiar, so familiar."

When Li Shimin saw this, he was also moved.

When flower growers made their own mushroom bombs, didn't they only give them a few years?

If you do it, it will shock the world.

If we fail to do so, we will once again fall behind and be beaten.

The situation at that time was much more difficult than it is now.

But to the critical extent of the problem, some people have taken care of it before.

Now, this team has to start from scratch!

Everything must be studied by oneself. Although the emperors do not understand, they also know that this is still a big problem!

And will the team succeed in the end?

It has become an unavoidable question in the minds of everyone looking at the sky.

The key is that even if it succeeds in the end, no one can be sure that problems of this kind will not occur when it is finally implemented.

After all, this is something from scratch!

There is nothing wrong at all, it is simply impossible.

So until now, it can be said that everyone still maintains a pessimistic attitude.

…

[In two years, this team started from scratch, explored and made mistakes over and over again.]

[Several key technologies of variable thrust engines have been broken through successively.]

[Finally, Chang'e-3 sees hope.]

[But design is only the first step. The more important thing is to find problems in the design through continuous testing. 】

[During actual flight operations, the surroundings are vacuum, so it is necessary to create a test condition that simulates vacuum. 】

[That is to install the engine in a vacuum chamber and conduct long-term and long-distance assessments.]

[However, another big problem has arisen. The existing vacuum operating tables do not meet the existing requirements. 】

【what to do?】

…

Zulong: "Build one yourself!"

Qin Shihuang's infrastructure gene awakened again.

The video seems to echo Zulong’s thoughts——

…

[If it doesn’t work, build another one!]

[From then on, under one of the ridges, it continued day and night. 】

[There are only four years until the scheduled launch of Chang'e-3.]

[The team responsible for the construction of the test bed did not dare to delay even a day.]

[The tasks received in April of that year were required to be completed in September. 】

[You know, this is not about building a house, just as many people as possible.]

[The variable thrust engine team is created from scratch;]

[The construction of this test vacuum platform was also made from scratch!]

[The time left for others is at least measured in years.]

[However, the time given to this team is measured in months.]

[And there is not even half a year, only five months! 】

[In five months, it’s not about designing, but actually building a plan from scratch into reality!]

[If one part of the construction is wrong, then all the efforts in less than half a year will be in vain!]

[So, the difficulty the team faces is not only to innovate, but also to not make mistakes! 】

[On this basis, we must also create a final product that meets all the questions raised by the design team. 】
