"I intend to install forty guns, twenty on each side"

Yang Bo was completely immersed in his own conjecture: "I will paint all the hull black and hang the symbol of the black skull, well, just call her the Black Pearl, powerful firepower, streamlined shape, and unparalleled speed, enough to make her a new generation of overlords at sea!" What Zheng Yiguan, Liu Xianglao? It's all a scumbag in front of her......"

"Lord Yang, is your spring dream finished?" Chen Bilian coldly interrupted Yang Bo's memories

"What's wrong?" Yang Bo was inexplicable

"Lord Yang treats this girl as a three-year-old, right?" Chen Bilian sneered, revealing a mouthful of snow-white glutinous teeth

"But the girl thinks something is wrong?" Yang Bo was stunned, this is a complete copy of the clips in the movie, what's wrong?

"It's okay for Lord Yang to fool others, but you want to fool this girl? Hmph," Chen Bilian shook her head, "Lord Yang, you might as well send me back."

"If the girl has something to say, she will say directly" Yang Bo is very modest, and he is not traveling through the encyclopedia, where does he know so many things?

"First, this artillery can't hit 300 steps at all, and the water in your lord's words is very heavy?" Chen Bilian turned her back and motioned for Yang Bo to let go of her hand, Yang Bo waved his hand at He Jiu and stepped forward to untie her.

Chen Bilian rubbed her wrists, looked at Yang Bo with a smile and continued: "Second, twenty artillery pieces on each side? Have you ever counted how long this ship is? ”

"Nope"

Yang Bo's scalp was a little numb, so he said it casually, it seems that the cowhide blowing hair was caught by Chen Bilian.

"Third, since the ship is full of artillery, where does the speed of this ship come from?"

"This ......"

Yang Bo was speechless for a while, he forgot that Captain Jack's ship didn't need power to run fast, and this copycat Black Pearl didn't have that ability.

"My lord, do you want me to continue?" Seeing Yang Bo's embarrassment, Chen Bilian was extremely happy, and the depression of the past few days was swept away.

Yang Bo was silent for a long time, and suddenly squatted down

"Come!"

Chen Bilian hesitated slightly, walked to Yang Bo's side, but saw what he was drawing on the sand.

"Miss Chen, please look, these are two ships facing each other at sea."

Yang Bo drew the appearance of two boats on the sand: "Suppose the distance is three hundred steps!" ”

"Huh? So what? Chen Bilian was attracted and squatted beside Yang Bo

"This ship" Yang Bo pointed to the sea: "I will change it into two layers, the lower layer is opened, and the small cannon of the Franc machine is placed, and the firing range is about 300 paces......"

"Wait, that kind of Furlong cannon can shoot three hundred paces?" Chen Bilian is a veteran on the ship, and she is very clear about this kind of common sense problem

"Of course, other Furlong cannons can't reach it, but my Maojiatun can" Yang Bo patted his chest.

The main disadvantage of the Furlong machine not being able to shoot far should be the airtight surname between the son and the mother, because the connection is not tight, there will be a large amount of gas leakage during launch, resulting in the weakening of the range power.

Yang Bo will try to solve this problem from several aspects:

First, at the part where the sub-gun is connected to the mother, that is, the mouth of the sub-gun, a ring of sealing hoops is made of lead or lead alloy, and the sealing hoops are heated and expanded when the gun is fired

sealing, thereby reducing gas leakage and increasing the power of artillery, if this is not enough, use cork chips to solve the problem of gas leakage

Second, the problem of low ignition rate of gunpowder is solved with granular gunpowder

Third, the problem of barrel pressure can be solved by using the method of iron-core copper cannon, so that more gunpowder can be loaded, and the problem of insufficient firing range can be solved accordingly.

The small cannon of the Furlong machine mentioned by Yang Bo is actually the No. 4 Furlong machine recorded in the Wubei Chronicles, which is "more than three feet long, each containing lead weighs 3 taels, and uses 3 taels of medicine" The record on the Wubei Chronicle is slightly exaggerated, but Yang Bo believes that the improved No. 4 Fran machine will definitely be able to achieve the predetermined range.

Seeing Chen Bilian's suspicious look, Yang Bo smiled: "Why should Miss Chen worry, if my Maojiatun can't solve this problem, then what else is there to talk about with you?" ”

"Okay, let's leave you alone, and then?" Chen Bilian put this question aside first, she needed to understand what Yang Bo's overall plan was

"Okay, Miss Chen, look, even if there are twelve small cannons on each side of the lower ship, how many times can the gunner fire the distance of three hundred paces?"

"If the enemy ship is downwind, three hundred steps to the flying claw to engage in a battle, the gunner will have to be two or three times at most, and he still needs to be proficient" Chen Bilian thought about it, not very sure.

"That's good, even if it's good twice" Yang Bo didn't care, if you didn't consider the problem of cannon barrel heating, three hundred steps was enough for a well-trained gunner to fire four or five times

"I still have a sharp weapon on the upper deck, girl, please see" Yang Bo drew a strange thing on the sand

"What is this?" Chen Bilian didn't understand it for a long time

Yang Bo explained: "I call it a mortar cannon"

"Isn't it just a bowl?"

Chen Bilian glanced at Yang Bo, the thing you painted can only be understood.

"That's right, this mortar cannon is used at a hundred paces, what does the girl think?" Yang Bo is full of confidence

"Isn't the bowl cannon just firing a few stone projectiles, what can it do?" Chen Bilian was suddenly disappointed, the idea of the Franco machine just now was very fresh, and it really made her heart move, if she could reach the distance of three hundred steps that Yang Bo said, but this mortar cannon was cumbersome, and it was difficult to hit the target, even if the people on the deck were waiting for you to fight, it would have to be lucky......

"Shoot stone projectiles? Is the girl joking? "Yang Bo is angry, but Lao Tzu is also a person from later generations, and he still promotes stone bullets in Daming?

"That's?"

Although Chen Bilian is well-informed, she is limited by the times and cannot keep up with Yang Bo's train of thought

"Blossom Bomb!" Yang Bo drew a line from one boat with a twig, connected it to another, and then made a "peng" sound from his mouth

"If this mortar cannon is fired and explodes on the decks waiting for the broadside battle, the girl thinks about it......" Yang Bo felt that he had made it clear.

"What is the principle of this flowering bomb?" Chen Bilian was pleasantly surprised, she was born in a pirate family since she was a child, and she was already very familiar with these conventional things after hearing and seeing them, but she didn't expect Yang Bo's words to let her see another broader world.

Yang Bo drew a circle on the ground

"This is the flowering bomb, pouring hollow iron and lead, adding iron and sand and stone gunpowder inside, inserting it with a slow-burning fuse, if you can control the burning time of the fuse, the power is not small" Yang Bo was very proud, he spent his boss's energy to check those esoteric books, in order to be able to get an inspiration, he felt that his vision was beginning to blur, but it was worth it.

Because the principle of his other sharp weapon, the Daming ** bomb, is similar to this mortar cannon.

"How many moves can you take?"

Chen Bilian suppressed her excitement and asked

"The mortar cannon is not big, it is enough to hit one or two hundred steps, if there is too much gunpowder, it is very easy to explode" Yang Bo has not fully figured out the pouring method of the circular hollow iron shell, and the possibility of this kind of flowering bomb blowing up the chamber is very high.

"Where's this mortar? Take me to see it" Chen Bilian finally couldn't help but be moved,

If according to Yang Bo's plan, at a distance of 300 steps, there will be a salvo of 20 Furlong machines, even if it can't sink the opponent's enemy ship, at least it will be half-disabled, after approaching the distance of 100 steps, the opponent's sailors will pick up their weapons and prepare to board the ship to fight, at this time it will be the turn of the mortar cannon, if Yang Bo said that five or six of the twenty flowering bombs hit the deck and detonate smoothly, it is estimated that it can blow down a large area, of course, Chen Bilian doesn't know, in Yang Bo's plan, if the fire gun equipment is in place, Waiting for the remnants of the enemy on the enemy ship will be the barrels of countless black holes......

"I haven't started building it yet......," Yang Bo replied with a sad face
