Daqin started with offering immortal medicine

Gongshu Chu was immediately dumbfounded, his mouth became an "O" shape in shock, and his whole body was messed up!

He suddenly discovered that Li Yang knew how to build a ship better than himself!

Chapter 299 Shivering

"The dean has built ships before?"

Gongshu Chu really didn't believe that Li Yang would come up with so many ways to improve sea-going ships because he had never built a ship before, so he couldn't help asking curiously.

Li Yang smiled and shook his head: "I don't know how to build a ship, I just saw a few sea ships!"

"..." Gongshu Chu showed a look that even he couldn't believe it, and looked at Li Yang dumbfounded.

I have only seen a few sea ships, but I can figure out that I have been building sea ships for more than ten years, but I have been unable to solve the difficulties of tackling key problems. Is this still a human being?

You must know that building a ship is not like building a small object. Shipbuilding is a huge system engineering that covers many fields. In-depth practice can be improved.

For example, if you don't know how to build a ship, don't understand the structure of a sea-going ship, and have no sailing experience, how can you tell the shortcomings of a flat-bottomed boat?

You do not understand shipbuilding, do not understand the structure of seagoing ships, and have no sailing experience, how do you know the disadvantages of hard sails?

Not to mention the theory that increasing the draft at the bottom of the ship can play a role in the stability of the hull.

Gongshu Chu really couldn't believe that these methods of improving seagoing ships came from a court official who had never been in contact with the shipbuilding industry. This is simply unbelievable!

In fact, Li Yang really didn't lie to him.

It is true that he has never built a ship, but he used to like to watch nautical adventure movies and popular science related to nautical science, such as "Pirates of the Caribbean". Li Yang still remembers the appearance of the sailboats in it.Among them, the sailing ships such as the Black Pearl, the Intrepid, and the Flying Dutchman are all three-masted sails with pointed soft sails, that is, three large masts.

This kind of sailboat sails at an extremely fast speed.

If the Qin Dynasty could build this kind of three-masted sailing ship at this time, the travel from Daqin to Shaohao could be shortened by at least half of the previous six months, that is to say, it would only take more than three months from Daqin to Shaohao.

In this way, they can go back and forth twice a year, which is simply a rapid improvement for the navigation industry at this time.

Although Gongshu Chu didn't understand why Li Yang had such a unique opinion on sea-going ships, as a person who has been working on sea-going ships for more than ten years, the method of improving sea-going ships mentioned by Li Yang , he still realized the subtlety of it as soon as he heard it.

For example, the flat bottom is changed to a pointed bottom, and the underwater part of the hull is more, so that the hull below the waterline is indeed increased, and the center of gravity is moved down to below the waterline. The lower the center of gravity, the more stable the ship is, and the ability to resist wind and waves stronger.

There is also a hard sail. Since there is only one support point, the area of ​​the sail is limited, and the extensive use of wooden skeletons also limits its ability to eat wind. Therefore, the speed is very slow, and the efficiency of cross-ocean sailing is low, which is not suitable for ocean trade and exploration.But instead of the soft sail mentioned by Li Yang, there are more support points, the area of ​​the sail can be larger, and the wind is strong, so the sailing speed and load will naturally be greatly improved.

To be honest, after listening to Li Yang's narration, Gong Shuji felt like he was enlightened, enlightened, and suddenly enlightened.

At this moment, he has a solution to all the problems that he has been thinking hard about before, and this feeling of being enlightened and completely awakened also made him feel a burst of excitement and excitement.

At this time, he couldn't control why Li Yang made such profound achievements in shipbuilding, so he immediately said to his subordinates: "Quick, get the model!"

Gongshu Chu actually wanted to improve the plan Li Yang mentioned on the spot on the ship model.

It has to be said that this guy is almost crazy in the study of sea ships.After all, the dean of the State Council is still inspecting at this time, so even if you want to implement Li Yang's idea on the model, you have to do it after the dean of the State Council leaves, right?

However, Li Yang didn't feel displeased in the slightest, instead he happily participated in it.

Soon, someone placed a sea ship model in front of everyone.

The model should be built with a ratio of 200:1, about 50 cm long, very delicate.

Gongshu Book directly turned over the model of the sea-going ship, dismantled the flat bottom in a few strokes, and then took wooden boards to make the pointed bottom.

At the same time that Gongshuji was modifying the bottom of the ship, Li Yang did not forget to add:

"In the future, the pointed bottom of the boat can be covered with copper skin to prevent the destruction of shellfish and enhance its service life and safety."

"In addition, a water-proof compartment should be installed at the bottom of the ship. Once a compartment leaks, it can be closed to prevent water from flowing to other compartments, and the ship will still not sink."

"In order to increase the stability of the ship, try to let the ship sail close to the water surface, and its underwater shape should also be designed to minimize resistance to increase the speed, but maintain a certain transverse resistance profile. The waterline surface of the bow can be designed to be long and wide The sharp curve scissors type can cut waves (cut waves) and move forward to reduce wave resistance at sea..."

"As for soft sails, it is best to design three-masted and four-masted full-rigged sails, using tall masts, and hanging moon sails and stay sails on the top-mast sails. It is also possible to design outrigger yards on both sides of the ship, which can be called It is a wing sail bar, which can be hung with a wing sail, so that the lateral extension area of ​​the sail can be increased. In addition, a slash can be extended outside the hull along the stem, so that some support triangle sails can be hung on the bow, which is conducive to expanding The holding capacity of the sail..."

"........."

Listening to Li Yangbi's boastful talk, Gong Shuji and everyone present were completely dumbfounded!

Everyone stared at him dumbfounded, as if they had seen a ghost.

Because Li Yang is not proposing an improvement plan at all, but is designing a brand new advanced long-distance sailing ship!

It’s fine if you want to state a brand-new advanced sea-going ship. What surprised Gong Shuji the most is that, according to Li Yang’s eloquent statement, this new-type sea-going ship is not just a concept, but is already very mature. up.

What kind of concept is this?

It means that this brand-new advanced sea-going ship hardly needs to be researched or designed, but it can be built directly according to the plan mentioned by Li Yang.

From the bottom of the boat, to the cabin, to the shape of the boat, the mast sail, and even how to design the shape of the bow, from the details to the naming of various sails, he has already named it for you.

Everything is extremely mature.

It was as if the boat Li Yang mentioned already existed.

"Dean, when did you start researching sea ships?" Seeing Li Yang paused, Gong Shuji swallowed and asked hastily.

In his view, without several years of research and continuous improvement, it is impossible to present such a comprehensive and mature sea-going ship design plan.

He Zhang was also very curious, because before that, he had never heard that Li Yang was researching sea ships.

I saw Li Yang glanced at the Gongshu Book in surprise, shook his head and said, "Research? I don't have time to study such things. I just talk about whatever comes to my mind!"

Upon hearing this, Gongshu Chu staggered, almost lost his footing, and fell headlong to the ground.

He was really shocked!

A brand-new and advanced long-distance ship with a mature design in all aspects, he actually... came up with it now!

Gong Shuchu swallowed subconsciously, and his body trembled a little.

Yes, this is really shocking!

"What, Dean, do you have anything to add?" Gong Shuchu was completely afraid to think about why Li Yang was so awesome, because he found that this problem had surpassed his own cognition.

Li Yang pondered for a moment, as if he finally had no more thoughts.

Seeing that Li Yang finally had no way to continue talking, Gong Shuchu felt a sense of relief, because this somehow made him regain a sense of reality.

It seems that Zhen Guojun's ideas have an end, and it is impossible to keep flowing. After all, Zhen Guojun is a human being, not a god.

And at this moment, I heard Li Yang say: "If I have to add, it is to build a hollow bow, because the hollow bow can make the bow of the ship easier to lift in the waves and improve the stability of the ship's course in the waves."
