"Dismantle your bright wheel, I'll teach you to make a little flower!" Bush has been out of his control, completely independent, and even surpassed himself. Pen, fun, pavilion www. biquge。 info Now Wen Xiaoqi's attainments in the steam engine are obviously not something he can guide, and this change makes Hong Tao, who has always regarded himself as a demigod, both relieved and uncomfortable. If you can't find a defect on the steam engine, you can't just spare Wen Xiaoqi, which will make you look too incompetent. What to use to protect his face, Hong Tao found a relatively easy thing, a propeller.

Compared with the paddle wheel, Hong Tao must be more familiar with the propeller, he has never even seen the paddle wheel, the propeller has seen and touched it. Wen Xiaoqi is right, the paddle wheel is indeed not very suitable for long-distance sailing, it is not only easy to be damaged after encountering wind and waves, but also changes the shape of the hull and increases a lot of resistance. After replacing the propeller, both sides of the hull are much cleaner, and strong winds and waves do not affect the work of the propeller.

"Go and get all your masters, and let them carve this flower out of the strongest wood according to my drawings." What materials are used to make propellers? Hong Tao finally chose wood. The metal propeller has too high requirements for technology, Hong Tao doesn't want to torture Qi Zu and Cixiang anymore, the boiler alone is enough for them to worry about, plus a propeller blade, this old and young can be tossed to death by themselves, and they don't know how to use metal to process the propeller.

Comparatively speaking, wooden propellers are easier to manufacture. The carpenters were able to carve sandalwood as hard as iron into hollowed-out balls, and there was no reason why they couldn't carve the slightly angled curved surface of the propeller blades. It is not a question of how big the arc is, whether it should be three or four or five, how long and what shape it should be. Carve out one of the same, try them one by one, anyway, there is no shortage of good wood, just let it be.

The carpenters in the shipyard are more relaxed than the blacksmiths who carry blowtorches and hammers all day long. They first sawed all the woods that could be found, such as North American beech, hemlock, black walnut, oak, African ebony, African red sandalwood, Brazilian sandalwood, etc., which were well dried in the shade and less than two meters in diameter, into half-meter-thick discs. Then, according to Hong Tao's description, the three-bladed, four-bladed, and five-bladed propellers were drawn out in various planing surfaces, enlarged in equal proportions, and painted on the wood of these large vegetable piers, picked up the chisel adze, and began to cut it with a clanging clang.

The eyes of these old carpenters are rulers, their hands are knives, and every chisel and axe is accurate. If two or three people work together, you can come up with a rough shape in one day, and after two days, you will start polishing, and if you don't need oil, you will definitely finish the work in three days. The specifications and dimensions drawn on the finished product and drawings must be exactly the same, and every detail must be polished and polished, without leaving traces of chopping and chopping.

Hong Tao wanted them to save some energy, don't work these experiments, they won't do it. In their words: no matter what the product is, as long as it is made by one's own hands, it must be done, otherwise it is not called work. The buyers are happy, and they themselves are not happy, and it is a shame to take out such a thing, and I am sorry for the craftsmanship handed down by the ancestors.

The propeller and steam engine alone can't be tested, and without the crankshaft and rotating shaft, this thing will have to wait for Qi Zu and Cixiang to finish their work on the boiler before they can continue to tackle the problem. Don't look at just turning the paddle wheel into a propeller, the realization is an update of the system, whether the roller bearing can be used, how to seal it is a problem, you need to gnaw the same, you can't rush.

But Wen Xiaoqi couldn't wait that long, and he couldn't sleep every day if he didn't understand what this little wooden flower was for. There was nothing wrong with the propeller shaft, he had a carpenter, who cut one out of hardwood; It doesn't matter if there is no boiler, he copied the transmission system of the Da Song car and ship, and the eight young men used pedals and took four sets of chains to drive the transmission shaft to rotate. This power combination will definitely not work on a large ship weighing hundreds of tons, so he found an inland river transport ship of about 20 tons as a test ship, specifically to understand the operation of the propeller.

"Haha...... Hahaha...... It's moving! "Don't say it, Wen Xiaoqi's method is really successful, when the eight young men shouted the trumpet and started to exert their strength, the boat really moved.

"Hurry up! Hurry up! When I go back, I have a treat, I can eat whatever I want, drink whatever I want! "The boat is moving, but the speed is relatively slow, Wen Xiaoqi has already understood in his heart, the faster the propeller should turn, the faster the boat will run.

"Let's kick the boat back first, our propellers are too big, even if you ask them to eat people's brains, they won't be able to pedal." Hong Tao looked at the stick guys in the eight shipyards and scratched their teeth for a while, and found that the speed of the ship had not increased much, and the boys were also pedaling very, very hard, and realized the problem.

Of course, the larger the diameter of the propeller and the higher the rotational speed, the stronger the thrust generated. However, the rotational speed is proportional to the diameter, if the diameter of the propeller is too large, the same force will inevitably reduce the rotational speed, and if it is changed to a human force, it is likely to not rotate. At this time, what should be done is not to play hard, but to change the diameter of the propeller to a smaller one.

Sure enough, after changing the propeller size three times, the boat finally reached its maximum speed under the human drive, and the speed was close to four knots per hour. Don't underestimate the speed of these four knots, this is driven by manpower. And the wooden propeller shaft can no longer withstand more people to do the work together, if you replace the steel shaft and steam engine to drive, the speed will definitely be faster, then the speed will be faster.

"O Divine Flower! It's just such a gadget, more powerful than my four paddle wheels! Divine flowers! Your Majesty, do you think I'm a success now? I've built a ship that doesn't need sails! "How fast the speed of the boat can be, Wen Xiaoqi doesn't care too much, even if it is only four sections, this is a huge improvement. Because of this set of things, the ship will be able to sail in the future, regardless of whether there is wind or not, and whether the wind direction is right or not. Burning coal without the need for human paddling is a huge step forward that could change the leap in the history of human navigation.

"I think so! In fact, when your steam engine can drive the loom to work, you have already succeeded. This kind of machine can not only be used on ships, but its greatest strength is that it can replace human work, and it can also do many tasks that cannot be done by human labor. Think about it, in the future, this kind of machine will get bigger and bigger, a steam engine can drive hundreds of looms, a day from morning to night tirelessly, how much manpower does this have to top? If the propellers on the ship are turned into wheels and then covered with Uncle Qi's steel rails, will this car be able to pull hundreds of tons of goods and run day and night? Wherever the rail is laid, it can run. In the future, the shipyard in your own kingdom will be built, Uncle Qi's steel keel and steel plates, the big trees you cut down, the minerals you excavate, and the grain you planted can all be pulled to the shipyard by these steam engines day and night, how much manpower will you save? Moreover, it is more convenient and energetic to use a steam engine instead of a water wheel to help you see wood and lift heavy objects. These machines only need to drink water, eat coal, and repair, and will not get sick or tired. Can you imagine what you've made? ”

Hong Tao didn't have much hope for the steam engine, let alone in his own development plan. But because of a small joke, Wen Xiaoqi spent more than ten years of hard work to get it out, and it is a practical model, this progress is a bit too big. It can be said that Wen Xiaoqi and Bush joined forces to change the entire history of human development, and the two of them advanced the industrial age by four or five hundred years.

This feats cannot be described in any language, and they are a hundred times stronger than any so-called great man. Now Wen Xiaoqi hasn't realized what he has built, and he must tell him to let him see further, and don't just think about building ships, building big ships, and building ships without sails all day long.

"Hahahaha...... I did it! Daddy! You should live a few more years, get on your son's big boat, and go around in a circle with black smoke! What our Wen family made, our ancestors won't! "It's a pity that Wen Xiaoqi didn't listen to Hong Tao's words carefully, first looked up to the sky and laughed, then knelt down on the deck, kowtowed to the east several times, and finally cried again, howling and crying.......

"Stop, don't be afraid, your master is happy." Hong Tao didn't persuade or bother, just silently watched the big man cry happily.

Crying and laughing at this time are no longer any different for Wen Xiaoqi, and there is no need to investigate what he is for. He insisted on one thing for more than ten years, and he was almost killed by sulfur vapor on a wrecked ship in Cape Town Harbor, and no one understood him except Hong Tao, and he still had no regrets about eating around for a little research funding. There are 10,000 reasons why he is crying now, and all of them are very sufficient. How do you persuade yourself? On what grounds to persuade?

And Hong Tao himself wanted to cry, but unfortunately there were no tears. Since I crossed into this era more than 30 years ago, the road I have traveled is not smooth, and there are stumbles everywhere. If it weren't for the memory in his head, if he hadn't met this group of poor Tan family members who had nothing to lose and supported him from beginning to end, not to mention the Mexika Kingdom, even the Golden River Empire itself would not have been able to get it.

It is estimated that he is at most the richest man in a small village on Hainan Island, not to mention Lin'an, maybe he doesn't even dare to come out of Hainan Island, for fear of being slaughtered as a fat pig by the Mongols. Thinking about the benefits, maybe he can build a decent sea boat, and then set sail to avoid the Great Song Dynasty occupied by the Mongols, and go to Dashi or Europe. Maybe you can mix up with a little lord or something, or maybe you will die when you touch a pirate, and you can't be a cheap place, and you will be burned to death by the church.

Now the world is unrecognizable, and chasing its roots is nothing more than a chance encounter between a passer-by and a group of fishermen. But Wen Xiaoqi has fulfilled his long-cherished wish in this life, but he has not finished yet. In order to save the Great Song Dynasty, he made a Jinhe Empire by himself, but the Mongols were beaten away and could not come back in a short time, but the Jinhe Empire was soon going to take the life of the Great Song Dynasty. He can't be as good as Wen Xiaoqi, he can last for more than ten years and finally get the steam engine out, can't he grit his teeth again and really save Da Song? At this time, Wen Xiaoqi became Hong Tao's role model, and Da Song himself was saved!

"Your Majesty, bring me a stick to taste, too, I see that you seem to enjoy it very much. I went to sleep after smoking, I was so tired that I didn't want to eat...... "I don't know when, Wen Xiaoqi finished venting, except for the red and swollen eyes, everything returned to normal.

"That's right, you can't eat a fat man in one bite, you should eat, you should sleep, your body is the capital of the revolution, you have lost all your capital, and you have made a fart fortune! But this cigarette, you better stop smoking, this thing is only suitable for treating lazy people like me, and it is also addictive, and it is not good for the body, you can't let it go if you smoke it. Hong Tao is considered to have arrived home, in order to prevent Wen Xiaoqi from becoming addicted to smoking, he always asked for it himself, and said a lot of nonsense, but he didn't give this cigarette in the end.
