Alphonse couldn’t help but nodded. The French instruments, rulers, and inches currently used in France have fluctuations. Although they are more precise, due to the underdeveloped gun casting industry and shipbuilding industry, their tolerances are definitely higher than those of gun casting.

The inches used by Britain, a large country, are larger; in this kind of precision industry, a 2% tolerance or a 5% tolerance can sometimes go very wrong!

It turns out that the rapid-fire cannon has a bronze body, and its smoothness and ductility are far better than cast iron. Using a 5% tolerance is not a big problem, but now it is obviously more dangerous. He thought for a while, and according to Yasuo's design, a solid hemisphere

It is about 165kg, and the three-stage gun body is 1484kg. After taking out the 220kg of the 5-inch inner tube, plus the gun lugs and the flintlock engine, the overall weight still does not exceed 3200 pounds (1452kg)!

Although the barrel length of the cannon is 4cm shorter than the original, its reduced power can be equalized by the further increase in air tightness. It can be said that Yasuo's greatest achievement lies in the creative hemispherical base and the 200-pound reduction that does not affect the mass.

Weight!

"I can't wait to see the birth of this artillery piece. Yasuo, let's have a drink." Alphonse raised his cup and smiled.

"In five days at most, I can cast the prototype." Yasuo smiled.

"It seems that I won't be able to see the test firing of the new cannon." An said with some regret, after all, she was going to Amsterdam soon.

"Maybe when you come back from Amsterdam, we can finalize the shape and start mass production." Yasuo laughed...

After Julia left, Alphonse sent Bardis to help Yasuo draw the design, so he took some time out of his busy schedule to watch the moonlight with An in the empty backyard.

"Are you not happy?" An looked strangely at Alphonse, who looked nostalgic.

"You are leaving, but if I am still happy, wouldn't it be too heartless?" Alphonse joked. In fact, he found that the moon in foreign countries is not that round, but he just doesn't know what is happening to his hometown, which was already the first year of Kangxi's reign.

.

"Hmph, who knows if you are leaving because of Julia?" Ann hummed proudly.

"By the way, part of the payment paid by Benjamin Hawkins is your commission. Do you need my help to send this money home?" Alphonse quickly changed the subject.

"Forget it, let's talk about it when I get back." An suddenly fell silent, probably thinking of something unhappy, and reached out to pour the hot cocoa on the table. Alphonse quickly poured the hot cocoa for her, and

According to her habit, she added half of the goat milk. After thinking about it, she suddenly asked strangely: "You seem to have never added sugar?"

"I don't like sugar." An immediately made a serious face, which made Alphonse a little confused. Cocoa is originally a sour and bitter chocolate flavor. After adding milk, the mellow flavor will be stronger, and a faint taste will burst out.

Sweetness comes, and Ann likes to drink hot cocoa. It is obviously unreasonable not to like sweetness, especially when she looks angry, which is even weirder.

Thinking of this, he reached out and held An's little hand tightly and said softly: "Did it remind you of anything unhappy?"

An was silent for a moment and then thought for a while before saying: "When I was a child, my family's conditions were very average and we rarely bought candies. My younger brother really liked eating candies, so every time I bought candies, it was my younger brother who ate them. My mother never gave them to me.

Slowly, I told myself that I don’t like sugar, and it didn’t feel so bad.”

"You should have told me a long time ago." Alfons held An in his arms. In fact, he cared very little about An, and in and out of his words, it seemed that she loved her family very much and would not hesitate to work and earn money to help.

My family was still in debt, but I didn’t expect to live in such an environment that favored sons over daughters throughout my childhood.

"So what if I tell you? They are my family." An replied with a pout. They are Catholics. No matter how unreliable her parents are, if they do not support her, it will be difficult for her to get a dowry and blessing when she gets married.

.

This often leads to her eventually becoming the mistress of a powerful person and living a life where she cannot raise her head to meet others; so even for her own future, she cannot blatantly break with her parents until she becomes

Until the wife of a certain family’s official matchmaker is marrying.

"You can also treat me as your family member. You know, I don't have any relatives anymore. I was even kicked out by my brother." Alphonse shrugged and joked to himself.

"At least you still have money and Mr. Alfred." Ann replied, nestling in his arms.

"Don't worry, you will soon be richer than me now. When the time comes, donate to a nobleman. What do you think, Lady Charles?" Alphonse said jokingly.

"It's too expensive." An rolled her eyes. A lord costs livres, and being a baron costs about 100,000. The viscount needs to invest at least 20,000 to 300,000 livres together with the purchase of land. With this money, she can be her own boss.

Aren’t capitalists good?

Alphonse smiled and said nothing. The earl plan he planned for Little William even required an investment of 1.8 million livres. If it weren't for the fact that the highest level of the nobility system is to sell to a viscount, he might even want to spend money to buy a duke in the future.<

/p>

"By the way, I've sent someone to prepare the mold. I'll get you a mirror in a few days. Aren't we going to participate in the auction next month? We'll get a piece for auction then." Alphonse smiled: "

I’ll use the money from the sale to take pictures of your exhibit.”

"Are you really good at making mirrors?" An suddenly became energetic.

"I am a person with magical powers. As long as I want to do something, I will find a way. Just wait and receive the gift when you come back." Alphonse smiled.

"Hmph, if you can't make it, go to Venice and buy one for me." An gestured with her hands and said, "I want such a big mirror!"…

An went back to pack her luggage and get ready to go out tomorrow, while Alphonse had to prepare himself a cup of rich original hot cocoa and prepare to stay up all night to design the precise shipbuilding drawings. In fact, it was impossible for Alphonse to design the complete shipbuilding drawings.

After all, the truly complete drawings even include the curvature, size and layout from the keel to the ribs, all the way to the design of the mast, rigging and even the blocking!

There are as many as 280 total design drawings for France's iconic 74-ship flagship in the future. Even if Alphonse had three heads and six arms and just put the drawings next to him and asked him to copy them, he would not be able to draw 280 drawings overnight, so

In fact, he only drew six drawings:

The first picture is the keel diagram. In order to tilt the bow forward, Alphonse designed the keel as much as possible for a flying shear ship. However, considering the current processing technology, he only adjusted the inclination angle from 30 degrees to 45 degrees. In addition, he adjusted the keel angle to 45 degrees.

The convex bone reserved for installing the ship's bow image also serves as the bow extension bracket. The logo requires that this triangle be extended to cover the front deck;

At the same time, he painted a bracket structure and a dovetail mortise and tenon structure on the side. This is the wisdom of Eastern woodcraft technology passed down for thousands of years, which can make the connection between the keel and the ribs stronger and the force more even. Alphonse

I think that just by learning the two mortise and tenon structures on this drawing, the Dutch are basically worth a boat.

The second picture is the mast layout and rudder layout. The front mast is connected to the keel elbow, so it has an inclination angle of about 80 degrees. It can obtain greater propulsion when the wind is downwind, and it will also push the bow down slightly.

, lest the bow of the boat almost float out of the water when the wind is too strong!

The mainmast is set at the center of gravity of the ship. How to determine the center of gravity, Alphonse cleverly chose the golden ratio of 0.618 on the deck axis from bow to stern; although this may not be the most accurate point, it is

At a position slightly to the right of the midpoint of the axis of the bottom of the boat, Alphonse knew that his choice was probably right.

The tailmast passes through the poop and falls in front of the turning point of the keel. Because Alfons considered using a rotatable spinnaker for the tailmast, the sailman can stand on the top of the poop and adjust the spinnaker 180 degrees.

direction; this will greatly improve the sail performance of the sailboat, cut the wind quickly, and greatly increase the minimum speed of the sailboat!

The third picture is the layout of the cabin. This is Alphonse's specialty as a sailor for many years. How to pack as many things and people as possible into a ship of limited size while making the best use of the space.

And try to put related functions together as much as possible.

This ship has 22 16-pound guns. Just the sailors to operate the cannons need up to 12 groups of 11 people, which requires nearly 132 people. In addition, it takes at least 22 people to drive the ship. In addition,

There are observers, helmsmen, captains, first mates, damage control teams, cooks and boys, with a standard manpower of up to 170 people!

Food and fresh water reserves must be sufficient, the passages must be as convenient as possible, there must be many isolation compartments, and damage control teams must be distributed in place. Then the gunpowder and ammunition required for the 22 artillery pieces, as well as the future four sets of sails, a pair of spinnakers and

With two bowsprits and spare sails, corresponding cables, repair wood, etc., most of the space in this boat needs to be filled to the brim.

Despite this, Alphonse still needs to carve out four warehouses, two large and two small. After all, if the robbery is successful, it will be embarrassing if there is no place to put the loot...

The fourth picture is the layout of the two decks. Alphonse had to reduce the number of sailors as much as possible, so he opened two doors on the second deck partition so that the gun crews on both sides could use the same manpower: such as powder boys and loaders.

, it will reduce the number of people equipped with two artillery pieces to two on each side, and a total of four artillery pieces equipped with one person. Just in this way, 22 artillery pieces can compress 11 people;

In addition, the gunner and gunner are only configured in 3/4 configuration. 22 guns are equipped with 15 gunners and 11 gunners, and the single-side salvo is only 9 guns. This configuration can be covered anyway, and the gun

The commander himself can also serve as the artilleryman, with a total of 26 people, and there is still a surplus of 4 people that can be lost, so that the configuration of 12 people can be reduced;

The fiber-drawing sailors are also only configured in 3/4, and can reduce the number of 17 people. In this way, the standard configuration of the entire ship can be reduced from 170 people to 131 people.

The other is to move the toilet from the bow to the stern. After all, the boat is moving forward, and the toilet is not at the stern. Doesn’t the excrement and urine go to the hull? In addition, the rudder stock layout is also closely attached to the forecastle.

Maybe the shipyard will find it strange, but Alphonse, who decided to change the steering wheel, thinks there is nothing to explain to the shipyard...

The fifth picture is a three-dimensional view of the ship's appearance. This is to ensure that after the merchant ship is built, whether it can be compact and organically blended together depends on the three-view appearance parameters for verification. It is also the time for Julia to follow

An is the basic reference for ship acceptance. If the three drawings are very different, it goes without saying that the other party did not build the ship according to these drawings.

The sixth picture is the renderings of Alphonse's expected modification. One is a hollow nose bow, the other is a bowsprit, and a steering wheel. As for the movable rigging, hull armor, wing sails, etc.
