Please ask me to be the emperor

"Your Highness, please see, this is the 'definite model' of the bird ship made by Chen Rang's craftsmen." Zhang Zizhou, the new director of Tianjin Shipyard, held a wooden model and dedicated it to Zhang Shundao.

"Oh?" Zhang Shun took it and took a look. It turned out to be half a bird ship model. He couldn't help but look at Zhang Zizhou in confusion.

"Determining the side pattern, also known as 'spotting the grass frame', is a method learned from house construction," Zhang Zizhou explained quickly.

"First, use a ruler as a foot, an inch as a ruler, an inch as a centimeter, a centimeter as a centimeter, and a millimeter as a centimeter. Draw a side view of the building on a flat wall..."

"Oh!" Zhang Shun observed carefully first, then listened to his explanation, and immediately understood what it was.

It turns out that when Zhang Shun built a house in his previous life, he first designed the drawings, then made a technical briefing, and finally constructed the project parts by parts according to the drawings.

The average level of education of the craftsmen of this era was naturally not as good as that of later generations. Most of them neither knew how to make standard drawings nor could they understand the drawings, but the project still had to be carried out, so what should we do?

The technicians at that time thought of a simple and easy-to-understand method, which was to make a proportional longitudinal section model.

This can not only show the appearance of the finished product, but also show the internal structure, which can be said to kill two birds with one stone.

The "definite profile" presented by Zhang Zizhou is actually a proportional longitudinal section model of the bird boat.

"Your Highness, please see, this bird boat has three sails and two masts, and two oars behind it. It is most convenient to raise the sails when there is wind and rock the oars when there is no wind." Zhang Zizhou couldn't help but pointed.

"There is an anchor in front, a rudder in the back, a 500-pound cannon at the front and rear, and two thousand-pound furlong machines."

"Compared to the original Haicang ship, it is not only more powerful in firepower, but also more flexible and faster..."

"Hey, why is there a gap in the bow of this ship?" While Zhang Zizhou was talking endlessly, Zhang Shun suddenly pointed at the bow of the ship and asked.

It turns out that in Zhang Shun's past life memory, most sailboats had sharp bows.

This bird boat, on the other hand, not only does not have a sharp bow, but it has a piece less than the other boats. It looks like a gap.

Moreover, not only is a piece missing from the bow of this bird ship, it is also completely dark green. The craftsmen also painted green eyebrows, a red beak, and black eyes, making it look like a strange bird.

"Oh, Your Highness doesn't know, this is the characteristic of bird boats!" Zhang Zizhou couldn't help laughing after hearing this.

"Because this bird ship is very fast and is easily hit by waves, two pairs of side panels were added to the left and right sides to prevent waves, which is how it looks like."

"Then... won't the bow of the boat catch the waves?" Zhang Shun thought to himself: If we want to prevent waves, why not prevent them completely?

"Your Highness, you are an amateur now!" Zhang Zizhou couldn't help laughing, "These ships are generally light in front and heavy in back, with a high bow, so they can ride the wind and waves and sail on the sea."

"The bird is on the sea?" Apparently Zhang Shun also understood that the bird was not a floating bird, but a bird.

Fu, wild duck, also extended to swimming.

In fact, the ancient Chinese ships were not modeled after fish, but at waterfowl.

This is especially true for this bird boat. Its shape also imitates the swimming posture of water birds, with its head held high and its tail raised, walking on the water.

"Oh!" Zhang Shun nodded in sudden realization, then pointed to the sharper bow and said, "Then this place is used to break waves?"

"Your Highness is wise!" Zhang Zizhou nodded and complimented Zhang Shun calmly.

However, Zhang Shun didn't care about this and frowned instead.

It turned out that although this boat was a good boat, its shape was far different from the impression he had in his previous life.

It's just normal, but now is the time to use troops at sea, so you can't be careless.

Thinking of this, Zhang Shun couldn't help but said: "This ship is very good, but besides me, I can build another one for comparison and testing."

"Oh? I wonder what improvements your Highness wants to make?" Zhang Zizhou couldn't help but wonder.

"That's it. Although the bow of the ship looks like an inverted figure, in fact, the sides of the ship's bow are not floating outwards, but buckled inwards." Zhang Shun explained, "Then, can you first put these two sides together?" It changes to a flaring shape, and then the bow of the ship changes to a forward bulge like hitting a corner?"

"What's the use of this?" Zhang Zizhou couldn't help but be surprised.

"I can't tell clearly, but according to my feeling, it should be able to stabilize the hull and increase the speed."

It turned out that Zhang Shun had been thinking for a long time and suddenly remembered the difference between the bows of later ships and this ship.

The bow structure of later ships is different from this ship. One is that the bow has a big nose, and the other is that the two sides of the deep V-shaped bow are straight or flaring. It is rare to have this kind of internal buckle shape. .

Although it is said that due to the different environment between later generations and the late Ming Dynasty, designs that are suitable for later generations may not be suitable for this life.

However, Zhang Shun believed that to the extent of development in later generations, this structural difference must have profound meaning.

Moreover, based on common sense, if the sides of the bow are flaring, it will definitely be beneficial to the stability of the ship.

How can you imagine this Shun? Just this subtle difference is the result of hundreds of years of exploration by later generations.

It turns out that this kind of outward-floating bow is exactly the "flying scissor" bow structure, which was the bow used by the famous "flying scissor ships" in the United States in the 19th century.

The big nose on the bow of the ship is the "bulb nose", a design that emerged in the 20th century that can reduce water resistance and improve sailing speed.

Although it involves many complex principles and designs, this does not prevent Zhang Shun from adopting the "borrowing principle".

"Okay, this is quite simple. When the craftsmen try it out, I'll just ask them to add one more boat!" Zhang Zizhou nodded after hearing this.

Anyway, the other structures are the same, except for the structural changes of the bow and bow. The labor and materials consumed are not large, and it is all just to make His Highness happy.

Of course Zhang Shun didn't know that his suggestion was regarded by Zhang Zizhou as a typical example of "a layman guiding an expert".

"Okay, let's do this for now!" Seeing that things were almost done, Zhang Shun was ready to serve tea to see off the guests.

"Your Highness, Dongjiang Town has sent some wood. Among them is a man who calls himself 'Sai Heihua', who claims to be stronger than steel. I wonder if Your Highness would like to take a look?" At this moment, the sound of rising and diving could be heard outside.

"Oh? It's a good time to bring it in and take a look at it together while Director Zhang is still here!" Zhang Shun heard this and ordered quickly.

"Your Highness, look!" Not long after, Gao Qiqian came in with a few soldiers and presented seven or eight kinds of wood. He pointed at one of them, a dark brown wooden pole about a handful thick, and said with a mysterious face.

"Oh?" Zhang Shun looked at this ordinary leather-covered wooden pole strangely, and said it was a gun pole that was brought up.

He couldn't help but reach out and grasp it, but when he picked it up, it turned out to be heavy.

Zhang Shun couldn't help but laugh and said: "It's so heavy, could it be filled with lead?"

"No, Your Highness, this is what this black birch is. It originally grows in Liaodong, Korea and other places. It is as hard as iron and difficult to cut." Gao Qiqian quickly explained using his new knowledge.

"Oh? In that case, how can this wood be cut down?" Zhang Shun looked at it again and shook his head.

"I have also asked this question. It is said that all things are invincible. Although this wood is difficult to break with gold and water, it is only afraid of fire." Gao Qiqian responded quickly.

"When cutting down, first use fire to burn the iron red, scalding the tree body, and then cut it down."

"Oh? It looks like the cost is not low!" Zhang Shun frowned and turned to Zhang Zizhou and asked, "Do you think this kind of wood can be used on ships?"

"If it can withstand blisters and insects, this wood will be of great use." Zhang Zizhou smiled when he heard this. He couldn't help but stepped forward to take a look and said in surprise, "Hey, this wood is extraordinary, isn't it?"

"how do I say this?"

"Your Highness, look at the texture of this wood. It is extremely tight. This is the first time I have seen it since I supervised the construction of the ship!" Zhang Zizhou couldn't help but explain.

"If it is true as the Dongjiang headquarters said, this wood is so hard that it can be used as a keel, then the giant ship will be indestructible!"

"Hey, don't tell me. According to what the envoy said, this wood is impervious to water and can be chopped with a knife. It's not really suitable for use!" Gao Qiqian heard the words and answered.

"Oh?" In this case, Nachen will return to Tianjin and conduct experiments immediately! "Zhang Zizhou was very excited when he heard this and quickly excused himself.
