"Whoa...... Look, it's amazing! Bush was still in extreme excitement and did not understand what Hong Tao meant by giving him a small stick. Pen ~ fun ~ Pavilion www.biquge.info his master usually doesn't have a door, nine and a half sentences out of ten sentences are nonsense, who knows which sentence should be listened to carefully, which sentence is useless. In order to make the master a little happier, Bush picked up a bucket of water and poured it directly on the candle that was still burning. A miracle happened, this candle was not afraid of water, and even burned brighter.

"What's in it besides aluminum powder?" Hong Tao was really convinced, and he couldn't make such a thing even if he did it. I've heard of the incendiary stick, but I don't know how to do it, so I have to ask my apprentice.

"Chlorine, acid, potassium 40%, potassium nitrate 20%, aluminum powder 40%, diluted with fish gelatin and cured. The rope in the middle is not for ignition, and if there is no rope, the rod will break, and it is much stronger with a rope. This is what Uncle Qi taught me, and he said that he used to make candles himself. Bush didn't have so many thieves, and not only did he explain the ingredients, but he also explained the detailed proportions very clearly.

"Chlorine\Acid\Potassium...... You have to pay attention to this thing, it's very unstable, don't do too much until you get a way to make it stable. You have to live to discover more new substances, and you can't take risks, you know? If you have to do unknown and dangerous experiments, let the apprentice do it. It's not that the master is ruthless, you have to listen to the master on this issue. Your life is worth more than 10,000 apprentices, don't forget, you are walking in front of everyone, you are exploring the way for everyone, you must not die! ”

Chlorine, acid, potassium, potassium nitrate and aluminum powder are mixed together, why they do not extinguish when exposed to water, this chemical reaction Hong Tao probably figured out. Chlorine, acid, and potassium are strong oxidizing agents, which themselves can provide oxygen for combustion. The combustion temperature of aluminum powder is extremely high, which in turn provides the temperature for combustion. Potassium nitrate is a combustible, and the three elements of combustion are all complete, and the combustion reaction will not stop. However, chlorine, acid, and potassium are very dangerous, and they will react strongly when encountering high temperatures, humidity, and collisions.

"Well, don't worry, the apprentice you taught will definitely not die. Before I figured out the nature of the test object, I was reluctant to use it for my own apprentices, and they were all slaves...... But you are a thief, in the past few years, every year there have been slaves poisoned and injured, if I had been replaced, I would have become crippled long ago. In response to Hong Tao's warning, Bush's ears were about to hear a calluse. But he didn't bother, because the facts told him that what Hong Tao said was absolutely correct, which was one of the reasons why he trusted and admired his master so much. Without the guidance of the master, let alone researching new substances, I would not be able to save my life.

"Hey, hey, hey...... You kid is more thief than Master! Hong Tao felt that Bush was a good apprentice, not only to learn his own knowledge, but also to learn his own life-saving experience, which is the key.

"I'll show you another good thing, this was originally intended for the Navy, but Swann found out, and he forced me to use it for him first. But I still left some for the navy, can you help me see if it works! Bush laughed with Hong Tao as he put his hand into his big leather bag, and this time pulled out a 75-millimeter copper-shelled shell.

"You put cannonballs, grenades, and incendiary sticks in your school bag and run around the streets!" Hong Tao didn't even feel surprised, just now he felt that Bush was relatively reliable, but now it seems that he is also a madman. Normal people who have nothing to do when they go out with a bag of big killing weapons, can't they keep it first, and then send someone to pick it up when they use it? Just ten minutes away?

"Hey...... I'm not afraid I won't be able to catch you. You see, the beggar came when he smelled it...... "Bush has his own reasons, and it is all to blame on Hong Tao, and he also has corroborating evidence, and the thin man who came from a distance is his reason." Wen Xiaoqi didn't wait for Hong Tao and chased after him from the shipyard.

"Xiao Qi, you rest here for a few minutes first, I'll take a look, and then I'll go with you right away!" Without waiting for Wen Xiaoqi to open his mouth, Hong Tao sealed his mouth first. Looking at his appearance, he must have not closed his eyes all night, and Hong Tao couldn't bear to ignore him with words.

"I knew it was you kid, I'll dismantle my machine tomorrow and don't give it to you, something without conscience!" Wen Xiaoqi ignored Hong Tao, sprinkled all the evil fire on Bush's head, sat down on the box in the bunker angrily, and kicked out the burning incendiary rod with one kick.

"Right now! It's over right away, I'm going to go over and shoot it! "Bush has a lot more respect for Wen Xiaoqi than for Swan, how to say that Wen Xiaoqi is also an old-timer, and he is all playing craft.

There were two Qizu guns on the shooting range, which were used for testing, and Bush found someone to poke a thick plank at a position of 300 meters, and then returned to the gun position and directed the gunner to stuff his shell into the chamber. After a muffled sound, the wooden target was hit by sawdust and hit the target. But it's useless, at a distance of 300 meters, it's still a ground shooting fixed target, and missing is the problem.

"Don't worry, it's been a long time since he got this thing, we've all seen it, and the naval battle is really useful. You have taken in a good apprentice, otherwise I would not have given him my machine. Hong Tao didn't see any difference between this cannonball and ordinary cannonballs, and glanced at Wen Xiaoqi with a puzzled look. Wen Xiaoqi didn't look at the shooting situation at the observation port, but squinted and leaned against the wall to recuperate. After discovering Hong Tao's inquiring gaze, he said lightly, listening to what he meant, he was quite satisfied with Bush.

When Hong Tao put his face to the observation port again, two soldiers were already running towards the wooden target with buckets, which was emitting black smoke and flames from the hole that had been shattered by the cannonball. When the two soldiers poured two buckets of water on them, the flames and white smoke were only a little smaller for a short time, and soon they burned again.

"Hahaha...... Good stuff indeed! You're talking nonsense, have I ever taught a waste apprentice? You're the most wasted, let's go, go see your baby boiler! Hong Tao finally figured out what was in Bush's shell, this kid was really a genius, he actually stuffed the material of the incendiary rod into the warhead, used the heat of the shell to ignite the incendiary rod, and then used the high temperature of thermite to ignite the wooden hull.

The idea is very ingenious and scientific. The tracer bullet in later generations was made by using a metal incendiary agent stuffed into the tail of the warhead, which can not only mark the trajectory in the dark night, but also have a certain incendiary bomb function, and it will ignite when it hits flammable materials. And this process is very simple, you only need to drill a hole in the tail of the warhead, or simply leave a space at the time of casting, and then fill it.

"Your little seventh uncle can't wait, I'll go with him first, and then I'll come to you when I find time. If you think it's okay, start mass production. Painted green, for naval warfare. When he went out, Hong Tao ran into Bush who had just run back from the gun position, and he gave himself a lot of surprises, maybe there would be, but Wen Xiaoqi was still waiting on the side, and he couldn't favor one over the other.

Hong Tao and Wen Xiaoqi didn't go directly to the shipyard, and they couldn't make boilers by relying only on the blacksmiths and equipment in the shipyard, and they had to trouble Qi Zu. Compared with chemical knowledge, Hong Tao knows a little more about metal smelting and mechanical structure, after all, the major he studied back then was related to these, and he also went to the factory for internship.

This time, Hong Tao designed a simple fire-tube boiler for Wen Xiaoqi, saying that it was simple because the number of fire-pipes was too small, only three, distributed in a diamond-shaped circular boiler shell, and the top was a three-way connected to a chimney more than ten meters high. As for why the chimney is so high, it must make sense, in addition to using the air pressure difference to increase the furnace temperature, it is also to keep the smoke and dust as far away from the deck as possible, otherwise once you catch up with the tailwind, you will not be able to see anything on the deck.

Don't look at the fact that there are only three pipes, but it is not easy to make these three pipes watertight and have a certain strength, without the assistance of electric welding. Qi Zu was too old to carry the hammer into battle himself, so this job was replaced by his proud disciple Kindness. Five or six good hands drilled into the boiler, first burned the workpieces with a gasoline blowtorch, and then forged and welded them together with a sledgehammer.

This forging welding technology is very troublesome, to heat, beat, reheat, and beat again and again, but also to control the deformation and thickness of the workpiece, there is no process requirements, all have to rely on the experience of the blacksmith, do not follow a good master to learn for five or six years, can not play this thing at all. Even if they are all good blacksmiths, two or three people have to take turns to work for two days for a weld, and when they are done, they have to be fixed with rivets and then polished and inspected. A furnace body has to be several masters with more than ten apprentices to work for half a month, not necessarily a success, after pouring water and then heating, after the heat expansion does not leak before the final completion.

Hong Tao also didn't know how much steam this kind of boiler could provide, so he simply made three backups of different sizes at a time. In order to make the success rate as high as possible, Qi Zu and Cixiang slowed down the production of cannons, and transferred more than half of the good people in the foundry to focus on tackling key problems. This condition is not possessed by Wen Xiaoqi, and only Hong Tao commanded these people to work together to engage in a general battle.

In the past half a month, Hong Tao and Wen Xiaoqi have not been idle, the new boiler is improving, so there is no problem with the steam engine at all? I really can't tell if there is a Hong Tao or not, because the steam engine built by Wen Xiaoqi has broken away from his original design, and it is no longer a reciprocating cylinder, but four connected together. The first one is the smallest, the second is the largest, and the last two are medium in size, why is it designed like this, Wen Xiaoqi can't quite understand, he has completely tried it out through countless tests, and the power is the largest in this arrangement.
