Therefore, when Zhao Chuanxin and Miao Cuihua appeared on the deck, Rachel Kweis's face was still red.

She didn't even dare to look at the two of them, there was a sense that if she looked at them more, she would be seen through.

Zhao Chuanxin didn't pay much attention to it, but Rachel Cwis was always dodging, so he was curious: "Is it the sea breeze and I am confused?" ”

Rachel Cavis feels very excited: "No, no no ......"

Originally, they were all from the past, and they were no strangers to this kind of thing.

But the protagonist is Zhao Chuanxin.

At this time, Samuel Goldberg and Benjamin Goldberg, who were unaware, were engaged in a conversation about making a staff.

Samuel Goldberg said, "Benjamin, you should give me the money. You know what Dad is capable of, and when you make money, you can buy you a car or a house. ”

Benjamin Goldberg said: "It's the same with me, I have more money ability, and when I earn more, Dad, I will buy you a house and a yacht." ”

Money won't be given to you anyway.

Jiang Bo grinned when he heard it: One of these two can brag more than the other.

Zhao Chuanxin laughed and said: "You two are painting cakes in front of each other, see who can support them!" ”

The two masters: "......"

Benjamin Goldberg took out a book and asked Zhao Chuanxin: "Master, you see, this word is very obscure, what do you read?" ”

Zhao Chuanxin looked at it: "It's Yan, read bi." ”

"What do you mean by Master?"

"Master is what Master means, the death of the father is the test, the death of the mother is the concubine, and the master is better to live forever."

"......" Benjamin Goldberg nodded: "Master, then if I die, how can I write it?" Is it written about the love disciple Benjamin? ”

"Nope." Zhao Chuanxin shook his head: "If you die, write a great good!" ”

Miao Cuihua couldn't help laughing: "It's not in shape." ”

Zhao Chuanxin smiled: "Criminal, don't read too many books, your brain stem will be knotted if you read too much." ”

Samuel Goldberg, who couldn't understand Chinese, was next to him discussing clothes with Jiang Bo.

"What do you think of my custom suit?" Samuel Goldberg asked with a stinking fart.

This is something he paid a lot of money to customize.

Jiang Bo looked up and down: "It's not very good." ”

Samuel Goldberg's face froze.

Zhao Chuanxin knew that this kid had some goods in his stomach, so he asked, "What do you think of me?" ”

Jiang Bo sighed: "Shocking ugliness, this body will cause your dignity to ......"

"Blanch!" Zhao Chuanxin slapped him on the head: "Damn, dare to say such things to the boss, it's really nonsense." ”

Jiang Bo instinctively stiffened his neck: "I'm not wrong, one of the people present is counted as one, and only Sister Hua has the best taste in dressing." ”

Hey?

Zhao Chuanxin said, is it true?

He has always felt that his clothes are good, but he knows that Miao Cuihua has a unique talent for aesthetics.

Since there is an anchor point, it means that Jiang Bo is not deliberately suppressing it for the sake of pretending to be coercive.

He said: "In view of your dignity and inferiority, I will punish you to make me a custom set of clothes, just to examine your craftsmanship." ”

Jiang Bo stretched out his hand: "I have tools, but no fabric." ”

"I've got it ready for you, go to the cabin and get it."

Jiang Bo: "......"

There was nothing to do on the boat, and Zhao Chuanxin said he would do it.

When Jiang Bo came to the cargo hold, he found that there were all kinds of fabrics stacked inside, including tweed, fine wool and silk blends, worsted wool, and canvas......

He was shocked: "Zhao, are you going to take it back and sell it?" ”

"Nope." Zhao Chuanxin leaned against the cabin door: "This is all for me and my relatives and friends." The rest will be used for the tailor's shop. ”

Jiang Bo picked and chosen, selected the rolled cloth, took out the tools, and on the deck, with the bright natural light, began to tailor Zhao Chuanxin.

Samuel Goldberg grimaced and said, "By the way, make me a set too." ”

Jiang Bo rolled his eyes: "Why?" He is my boss, and you spend money on what you do, and the cost of fabrics and handicrafts is all indispensable. ”

Zhao Chuanxin blocked his vision with his body and secretly gave him a thumbs up.

See, that's a good partner.

Seeing that Zhao Chuanxin was rare enough to praise people, Jiang Bo was even more proud.

Samuel Goldberg muttered dissatisfiedly, "I don't know your craft yet, let's take a look." ”

He's right.

Jiang Bo said while measuring Zhao Chuanxin: "Traditional suits, in general, there are only three styles of British, American and Italian. If I go to work in Asia, I definitely want to make a suit that is tailored to the Asian body and fits the Asian body. ”

Zhao Chuanxin felt that he had found the right person.

He has seen photos of Sun Gongwu, his tunic, the starting point of the modification is good, but the rotator cuff is not handled well, resulting in the sleeve being crutched. Then there is not enough margin, resulting in a slightly split hem and stretched.

So a lot of things can't be just copied.

After measuring, Jiang Bo hurried back to his cabin with his tools.

Benjamin Goldberg said, "Master, let's study RPGs." ”

Zhao Chuanxin had just finished working, and he wanted to take a recliner, cover a blanket and rest on the deck for a while, flipping through the diary or something.

Because "I" is about to return to the city-state.

So he made excuses: "Aren't you cold?" ”

Benjamin Goldberg bent his head: "Since I practiced that kind of magic skill, I have not been invaded by cold and heat!" ”

Zhao Chuanxin saw that his face was really red and fluttering, and he looked very healthy.

Samuel Goldberg and Rachel Cvisjel, on the other hand, were pale.

"That's okay......" Zhao Chuanxin was reluctant to make it difficult.

The rocket launcher itself is very simple in construction, with a smoothbore steel tube, several stamped parts, and a wooden shell wrapped around it for thermal insulation.

The more difficult ones are the rockets, and the ergonomic effects of the launcher.

The weapon needs to be versatile.

One day in the future, Zhao Chuanxin will use it to deal with the first and second generation tanks that come to offend Maozi.

The master and apprentice quickly drew the design of the canister.

"Master, shall we build the launcher first?" Benjamin Goldberg asked.

"No." After all, Zhao Chuanxin knows that rockets are the key. "Let's design rockets to deal with various armored units and make them together."

Benjamin Goldberg couldn't get the point: "Master, are we going to wear armor?" ”

Zhao Chuanxin shook his head: "It's not armor piercing, it's armor piercing." Imagine that the conical head of a rocket hits the steel, not a breakdown, but a simple break, to eject the metal stream out of the projectile, accompanied by high temperatures. In this way, the people and equipment inside the armored unit suffered. ”

Benjamin Goldberg thought for a moment: "Then after the warhead hits the object, the force backward is very small, but the gunpowder has to be pushed forward." So we should design a tapered cavity. ”

Zhao added: "When the rocket is flying, it also needs to be kept stable. ”

Benjamin Goldberg immediately said: "The smoothbore canister needs to fly smoothly, so adding a tail to the rocket is the right choice, and the rocket will rotate." The rear design of the wind-oriented impeller with a relatively large pitch deflection. The launch canister is thin, so the tail fin is gradually opened during the flight. However, in this case, it cannot be launched close to the ground, or in the jungle or in a location where there are wires, because it will be entangled in the tail of the tail by wires and branches, which is really distressing, and there is no suitable way to solve it. ”

Zhao Chuanxin's eyes lit up: "Yes, that's it." You don't have to think about solving all the problems, even a large-caliber rifle is affected by wind resistance, let alone such a large rocket? ”

Cross-sectional drawings of rockets come to life.

In front is a conical head, in the front end there is a conical cavity, in the middle of which is in the shape of a half bowl, in which there is no gunpowder, it is completely empty.

Zhao Chuanxin frowned and watched.

With his knowledge and imagination, he could not understand the principle of this cavity at all.

The apprentice had to explain his confusion: "Master, this rocket should not rely on the power of a large amount of explosives to break the armor, we need to give the rocket a full burning space, the energy generated will be rapidly pressurized in this small space, and the power will be concentrated at one point to break the armor, and the hot metal flow will enter the inside of the car body through the steel plate, thereby destroying the personnel and equipment inside." ”

Zhao Chuanxin roughly understood.

When the rocket flies, gunpowder is fired backwards through the inclined nozzle to ensure rotation.

However, when it hits an obstacle, it ignites the fuse, and it will shoot forward.

This is the secret of why RPGs have such slow rockets and short ranges, but they can pierce armored tanks.

But here a new problem arises.

Zhao Chuanxin said: "How to design the impact fuse? ”

Benjamin Goldberg thought for a moment: "It's only through experimentation." ”

The master and apprentice used a conical round head, put a small amount of gunpowder, and conducted a free-fall experiment on the deck.

But it was found that if it was just an armor-piercing projectile, the classic fuse was acceptable.

But when it comes to high-explosive bombs, Benjamin Goldberg said, "It would be nice if there was electricity, and it could be triggered by electricity." ”

If Nikola Tesla's imagination is unbridled, with a lot of idealistic things in it, then Benjamin Goldberg needs to be based on his own cognition.

In his cognition, there seemed to be nothing other than Master's Mjolnir bracelet that could generate electricity in extremely small units.

Zhao Chuanxin suddenly thought of something - the electronics of the lighter.

But the principle he could not describe in too much detail, and could only say: "Silica crystals have a piezoelectric effect." When the crystal is under pressure, a voltage is generated on both sides. The higher the pressure, the higher the voltage, but not the amount of power. Connect a section of wire to play the role of ignition. ”

Benjamin Goldberg clapped his hands: "Although I haven't heard of it, if it's true, and a very small volume can produce an ignition effect, then the problem is completely solved." ”

Zhao Chuanxin nodded: "When you get ashore, call Nikolai, and you can ask him for advice." ”

Benjamin Goldberg was unconvinced: "Why use him? I was able to do the experiment myself. ”

"Ambitious." Zhao Chuanxin was relieved. "You should also have the ability to experiment independently."

"Of course." Benjamin Goldberg held his head high: "But I'm still used to the feeling that Master has quickly turned my ideas into reality. ”

“……”

The head is diligent and the limbs are lazy, right?

It's easy to build rockets on a ship, but it's not easy to experiment on a ship.

Zhao Chuanxin was not in a hurry.

He waved his hand: "You go back and refine it again, the teacher is now going to meditate on the recliner." ”

As he spoke, without waiting for the apprentice's reaction, he immediately took out the chaise longue and set up a battle, and took out the "Old God Codex......
