They call it 'tendons'.
This kind of rib will be spread throughout the inner and outer layers of the hull. The force dissipation effect of one rib may not be visible, but when there are a large number of ribs, the effect it plays will not be much worse than the keel.
This is a special structure that they came up with after racking their brains.
It looks no different from an ordinary ancient ship on the outside, but it is a completely different world on the inside.
After some sample tests, Team 9 believed that there would be no problem for the entire ship to bear a weight of 500 kilograms.
Xu Kai even recorded this structure completely in the shipbuilding drawings.
As the deductions and calculations of the entire team of Team Nine were realistic simulations, although there was still no plank built on the hull, the progress was officially on track.
After that, they were all busy with the problems with the hull.
Although new problems arise from time to time.
But they had completely changed their minds and did not encounter any real difficulties, and they continued to proceed in an orderly manner.
And in order to ensure the quality, they conduct a test every time they complete the splicing of a wooden board.
The most common test is waterproof testing.
For this purpose, they even got a large bucket of sea water.
Only if the newly put up wooden board can withstand twenty-one splashes of sea water without any leakage, will they consider it qualified.
And they will be marked with unique marks.
Of course, this kind of test is only during the construction. After the first layer is completed, they will conduct an overall test.
But then they would be in the sea, and they were looking forward to it.
I am also very fortunate that the warehouse rented by Teacher Ren has a seawater shipbuilding area on one side, otherwise it would be a problem to put a half-built ship into the sea.
Two days passed in this situation with a clear goal.
Two days later, the first-level bottom warehouse, which was about one meter high, was completely completed by Team 9.
It was glued and painted, and all measures were taken to prevent water, moisture and insects.
On the side of the shipbuilding area close to the sea, Team Nine laid a large number of rolling logs, and propped up their half-built ship from high to low. With a concerted effort, they pushed the ship that gave them hope into the sea.
When the waves splashed, everyone felt a strong sense of accomplishment.
After about a month, the boat built by their ninth shift was finally launched into the sea.
Although it is still just an embryo, it can finally be called a ship.
Apart from this sense of accomplishment, all that was left for Class 9 was worry.
They were worried whether the ship could really float on the ocean as they hoped.
The ropes used to secure the boat were tied to a corner of the warehouse.
Amid the tension and prayers of Class 9, time passed by minute by minute.
Even netizens and judges had some different emotions in their hearts.
They hope that the ship will float steadily.
Even though some of them opposed Ren Yan's plan to "go overseas" before, it is still the same now.
But at this moment, they really hoped from the bottom of their hearts that the ship would be successful.
These days, they witnessed the efforts of Class 9, and they didn't want to let this effort go to waste.
Even if this effort will bring hidden dangers to future events.
But they still have hope, and they feel in their hearts that the efforts these children have made in recent days "deserve" such success.
As for going out to sea, it is different from my current feelings.
In the parent group, the parents who often chatted and gossiped also fell silent.
A large number of 'digital' users have flocked to the live broadcast.
In the General Administration of Education, Ding Guoxiang was also watching this scene intently.
Everyone has a hint of expectation.
Ren Yan also watched everything in front of him.
Time passed by minute by minute, as if everyone was holding their breath.
The entire warehouse seemed unusually quiet.
One point, two points...
Five points, ten points...
There was still no sign of moisture inside the ship.
It was not until forty-five minutes later that Class 9 began to shout excitedly.
The entire warehouse immediately became noisy.
Many students even hugged their classmates next to them and took a big sip.
All the efforts for so long have not been in vain!
Forty-five minutes is the main time frame of their test.
At the same time, this time is also the time they calculated for paint and gum to become ineffective and fall off in sea water.
As long as there is no water leakage after this period of time, it means that there is no problem with their ship as a whole!
It seems that he was infected by Class 9.
Various netizens and judges also smiled heartily.
In the live broadcast room, various comments like "Class 9 is awesome" kept flashing by.
In the director's room, the judges were generous in their praise.
However, as they praised it more and more, they found that something seemed to be wrong.
How come after such a long time, Ren Yan, the teacher, doesn’t seem to be happy for even a moment?
Instead, the look he gave to Class 9 was filled with an indescribable "sympathy?"
"I'm talking to you, what's going on?"
Everyone was shocked and looked carefully at the "small half" of the ships on the screen again.
Then, their smiles stopped and were replaced by an extremely conflicted look.
Damn, this ship seems to be missing something...
No wonder it looks so awkward...
At this time, Class 9 followed Ren Yan's gaze and seemed to realize this problem.
They looked at each other with dejected and speechless expressions, and then all looked at Xu Kai.
"Mad, where's Fan?
!”
