"Disassemble your paddle wheel, I will teach you to be a little flower!" Bush had already left his control, was completely independent, and even surpassed himself. Now Wen Xiaoqi's attainments in steam engines are obviously not something he can guide. This change made Hong Tao, who has always regarded himself as a demigod, both relieved and uncomfortable. If there is no flaw in the steam engine, then you can't just spare Wen Xiaoqi like this, as this will make him look too incompetent. What can I use to protect his face? Hong Tao found a relatively easy thing, a propeller.

Compared with paddle wheels, Hong Tao must be more familiar with propellers. He has never seen paddle wheels before, and at least seen and touched propellers. Wen Xiaoqi said it well. Paddle wheels are indeed not suitable for long-distance voyages. Not only are they easy to be damaged after encountering wind and waves, but they will also change the shape of the hull and increase a lot of resistance. After replacing the propeller, both sides of the hull will be much cleaner, and strong wind and waves will not affect the work of the propeller.

"Go and find all your masters and let them carve this flower with the strongest wood according to my drawings." What materials should be used to make propellers? Hong Tao finally chose wood. The metal propeller has too high requirements for craftsmanship. Hong Tao doesn't want to torture Qi Zu and Cexiang anymore. Boilers alone are enough for them to worry about. With the propeller blades, the old and the young can be tortured to death by themselves, and he doesn't know how to use metal to process the propeller.

Relatively speaking, wooden propellers are easier to manufacture. Those carpenters can carve sandalwood as hard as iron into hollow balls. There is no reason why they cannot carve out slightly angled arc surfaces like propeller blades. As for how big or small arc surfaces are suitable, it should be three blades, four blades or five blades. How long should the blades be made and what shape is, this is not a problem. Carve one out and try one by one. Anyway, there is no shortage of wood, which is a disaster.

Compared with those blacksmiths holding blowtorns and hammers all day long, the carpenters in the shipyard were more relaxed. They first dry the shade. North American beech, North American hemlock, black walnut, oak, African ebony, African red sandalwood, Brazilian yellow sandalwood, etc., which are less than two meters in diameter, can be found. They are corrosion-resistant, have high strength and good mechanical processing performance, and all saw the half-meter-thick disks. Then, according to Hong Tao's description, they draw various planing drawings of the three-leaf, four-leaf and five-leaf propellers. After a proportion of the size, they draw on these large piers-like woods, pick up the chisels, and start cutting them with a jingle.

The eyes of these old carpenters are rulers, hands are turning knives, and every chisel and each axe is accurate. Two or three people cooperate to make the rough shape in one day, and they start polishing after two days. If you don’t need oil, you will definitely finish the work within three days. The specifications and sizes of the finished products and drawings are definitely not bad, and every detail must be polished and polished, and no traces of cutting the axe chopping.

Hong Tao wanted them to save some effort and not work hard on these test items. They didn't do it. In their words: No matter what kind of item it is, as long as it is made by one's own hands, it must be done, otherwise it will not be called a job. The buyers are happy, but they are not happy. It is embarrassing to take out such things. I'm sorry for the crafts passed down by our ancestors.

There is no test for propellers and steam engines alone. Without crankshafts and rotating shafts, this thing has to be done before Qi Zu and Cixiang finish their work on the boiler. As for whether to use a simple gearbox, I don’t know if it’s necessary to use it. Then, let’s talk about it. Don’t just turn the paddle wheel into a propeller, it will be a system update. Whether the roller bearing can be used or how to seal it is all a problem. You need to chew it all the same, and you can’t hurry up.

But Wen Xiaoqi couldn't wait for so long and didn't understand what this little wood flower was used for. He couldn't sleep every day. It was okay without a transmission shaft. He had a carpenter and cut one out of hardwood. It didn't matter if there was no boiler. He copied the transmission system of the Dasong ship. Eight young men used their feet to pedal and used four sets of chains to drive the transmission shaft. This power combination would definitely not be possible on a large ship weighing hundreds of tons, so he found an inland transport ship worth about twenty tons as a test ship, specifically to figure out how the propeller operates.

"Haha...haha... it's moving!" It's true that Wen Xiaoqi's method was really done, and when the eight young men shouted the horn and started exerting force, the ship really moved.

"Hurry up! Hurry up! When I go back, I treat you. I will eat whatever I want and drink whatever I want!" The boat moved, but the speed was slower. Wen Xiaoqi knew it in his heart that the faster the propeller should turn, the faster the boat would run.

"Push the boat back first. Our propeller is too big. Even if you ask them to eat people's brains, they can't kick it." Hong Tao looked at the young guys in the eight shipyards and gritted his teeth and stared for a while, and found that the speed of the boat had not increased much, and the young guys struggled to pedal, and realized the problem.

Of course, the larger the diameter of the propeller, the higher the speed, and the stronger the thrust. However, the speed is proportional to the diameter. If the propeller is too large, the same force must be reduced. If it is replaced with human power, it may not be able to rotate. At this time, what you should do is not to do your life, but to change the diameter of the propeller a little smaller.

Sure enough, after changing the propeller size three times, the boat speed finally reached its highest level under human power, and the speed is already close to four knots. Don’t underestimate these four knots of speed, it is driven by human power. Moreover, the wooden transmission shaft can no longer bear the work of more people. If you change to a steel shaft and a steam engine to drive, the speed will definitely be faster, and the speed will be faster.

"Shenhua! Just such a small thing, even better than my four paddle wheels! Shenhua! Your Majesty, do you think I'm successful now? I've built a ship that can sail without sailing!" Wen Xiaoqi no longer cared about how fast the ship could be. Even if it only has four knots, this is a huge progress. Because with this set of things, the ship can sail in the future regardless of whether there is wind or not, the wind direction is right or not. It only requires burning coal without people to row. This is a huge progress that can change the jump of human navigation history.

"I think it's up! In fact, when your steam engine can drive the loom to work, you have already succeeded. This machine can not only be used on the boat, but its most powerful thing is that it can replace manpower and also do a lot of work that manpower cannot do. Think about it, this machine will become bigger and bigger in the future. A steam engine can drive hundreds of looms, and rotate from morning to night without fatigue. How much manpower does it have to be supported? If the propeller on the boat is turned into a wheel and then the rails of Uncle Qi are laid, can this car pull hundreds of tons of cargo?

Run day and night? Wherever the rail is laid, it can run wherever it is. In the future, the shipyard in your own kingdom will be built. Uncle Qi's steel keels, steel plates, the big trees you cut down, the minerals you dug, and the grain you planted can be used to pull the carts driven by these steam engines to the shipyard day and night. How much manpower will you save? And using steam engines instead of water trucks to help you saw wood and lift heavy objects, which is more convenient and energetic. These machines only need to drink water, eat coal, and repair them, and will not get sick or tired. Can you imagine what you built?”

Hong Tao did not have much hope for the steam engine, nor did he be in his own development plan. But because of a small joke, Wen Xiaoqi spent more than ten years to make it out, and it was a practical model. This progress was a bit too great. It can be said that Wen Xiaoqi and Bush joined forces to change the entire history of human development. The two of them advanced the industrial era four or five hundred years.

Such great achievements cannot be described in any language, and are a hundred times better than any so-called great man. Now Wen Xiaoqi has not realized what he has built, so he must tell him to let him see further. Don’t just think about building ships, building big ships, and building ships that do not use sails all day.

"Hahahaha... I succeeded! Dad! You should live a few more years. Take aboard your son's ship and take a walk around in the black smoke! Our Wen family made it, even our ancestors would not! Woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo woo

"Stop, don't be afraid, your master is happy." Hong Tao did not persuade or disturb him, but watched the big man crying happily.

There is no difference between crying and laughing at this time for Wen Xiaoqi, and there is no need to look at what he is for. He has been persisting in a matter for more than ten days and was almost smothered by sulfur vapor in the abandoned ship in Cape Town Port. No one except Hong Tao understood him. He was still without regrets for a little research funding. Why did he cry now? There are ten thousand reasons, and each of them are very sufficient. How can he persuade him? What reasons should he use to persuade him?

Moreover, Hong Tao himself wanted to cry, but unfortunately he didn't cry. Since he traveled to this era more than 30 years ago, the road he had walked was not smooth and there were bumps and bumps everywhere. If he hadn't had memories in his mind, if he hadn't met this group of poor and had nothing to lose to support him from beginning to end, let alone the Kingdom of Mexica, even the Golden River Empire would not have been able to get it out.

I guess I am at most a richest man in a small village in Hainan Island. Not to mention Lin'an, maybe I don't even dare to leave Hainan Island, for fear of being slaughtered by the Mongols as fat pigs. Looking at the better part, I might be able to build a fairly slaughtered sea boat, then sail to sea, avoid the Song Dynasty occupied by Mongolia, and go to Dashi or Europe to go to Dashi or to make a fuss. Maybe I can be a little lord or something, or I might die if I touched the pirates. Maybe I would be a bad person and burned to death by the church.

Now the world is beyond recognition. The root of it is just a chance encounter between a passerby in time and space and a group of fishermen. But Wen Xiaoqi fulfilled his long-cherished wish in this life, but he has not finished it yet. In order to save the Song Dynasty, he created a Jinhe Empire, but the Mongols were beaten away and could not come back in a short period of time. However, the Jinhe Empire was soon to take the life of the Song Dynasty. He could not be worse than Wen Xiaoqi. He could last for more than ten years and finally get out the steam engine. Can't he grit his teeth and really save the Song Dynasty? At this time, Wen Xiaoqi became Hong Tao's role model, and the Song Dynasty was saved!

"Your Majesty, I'll give me a try. I think you're enjoying it. After smoking, I went to bed. I was so tired and didn't want to eat..." I don't know when Wen Xiaoqi finished venting, except that his eyes were red and swollen, everything returned to normal.

"That's right, I can't eat a fat man in one bite. I should eat and sleep. The body is the capital of the revolution. I lost all my capital and made a fortune! But you should stop smoking this cigarette. This thing is only suitable for treating lazy people like me. It is easy to get addicted and not good for the body. If you smoke, you can't let it go." Hong Tao was stingy. In order to prevent Wen Xiaoqi from getting addicted to smoking, he always told him a lot of nonsense, but he didn't give this cigarette.
