Sure enough, back in Xi'an, Wang Shuo directly took Tang Ruowang to the Academy of Sciences to find Wu Langxi.Two old classmates who graduated from the Italian seminary went to the mysterious East to explore the rivers and lakes together, and they were separated for more than ten years in the war.At this time, Wu Langxi learned that his respected teacher, Mr.
Galileo, had died in 1642, and he couldn't help but feel sad.Seeing the two yellow-bearded old men together, hugging and kissing, chattering endlessly, Wang Shuo was annoyed.What are you doing, what is this, you Europeans, this is really unacceptable, I have something to say later, I can't wait, I want to make a hot air balloon, fly to Beijing to burn the grain of the Qing Dynasty, hot air balloons Wu Langxi and Tang Ruowang know a little.However, this thing doesn't have the right materials, so it can't hold the heat.Also, it's not okay if the material is flammable, otherwise it will suddenly catch up in the sky, and the people above will finish playing.Wang Shuo said why are you so stupid, don't we have a waterproof tarpaulin, that thing is soaked in tung oil.Soak tung oil in thick woollen cloth, and add a layer of fine woven cloth outside to prevent the oil cloth from breaking.But what to use as fuel, Europe just can't solve the fuel problem, and many civilian experiments on hot air balloons have failed.You can't light a coal stove to go up to this thing, you have to be able to control the size of the heating source.The higher it rises, the less the source of heating it is, and the other way around, it increases.Moreover, the lift of the hot air balloon is limited, you bring more burning material and it can't move, you don't wait for the place with less, the fire is gone, isn't this a blind toss With the technology of Europe at that time, these can't be solved, so the concept of hot air balloons, just like China's Kong Ming lantern, has been there for a long time, but it can really carry people to the sky, or after the nineteenth century.Wang Shuo listened to the two of them chatter for a long time, and still said the same thing, you are really stupid enough to use the technology of making a steam boiler to make a smaller sealed iron can.Didn't you refine kerosene a long time ago and put kerosene in it?
On the sealed iron can, open two mouths, one mouth plus a piston barrel with a cowhide sealing ring, and process check valves and spring balls at both ends, this old Wu you will do.The purpose is to pump air and pressurize the sealed iron can.In the other mouth, a slender copper pipe is added to release kerosene atomized by air pressure.Why use copper pipes instead of iron pipes, copper pipes dissipate heat quickly, copper pipes should be designed on the copper pipe, but also extend into the bottom of the sealed iron can, and the front end air outlet hole should be smaller.In this way, the atomized kerosene is sprayed out through the small hole at the front end, we ignite it at the front end, and control the flame size through the control switch, and there is a stable heating source that can be controlled.Wang Shuo was talking on the side, and John Tang found a pen and paper and drew a picture according to what Wang Shuo said.After Wang Shuo finished speaking, Tang Ruowang's picture was also drawn.He looked at what he had drawn in surprise, and after a long time, he raised his head again and looked at Wang Shuo in surprise.After a long time, he said: "General, you are simply a genius, this thing should be feasible" Wu Langxi has long been surprised, he has seen things that are stranger than this.But this game should be much better than the telegraph, so that he will not be forced to go to the ground and the sky.He secretly breathed a sigh of relief.Every time Wang Shuo came to the Academy of Sciences, he was nervous and worried, lest the general come up with something strange for him to do, and he was about to get sick.Unexpectedly, Wang Shuo's next sentence made him nervous again.Wang Shuo asked him to make a hot air balloon for him within ten days, and the eight characters have not been skimmed, and after ten days, he will ask for a dripping yellow-bearded old man, and the Shaanxi dialect has come out.At this time, Tang Ruowang suddenly thought of another question, he was afraid that Wang Shuo would scold him for being stupid again, so he said for a long time: "Compared with the general, we are indeed a little stupid.But how can we compare with the great general, who is the messenger of God, who brings the gospel of God to the salvation of suffering mankind. ”Wang Shuo shook his hand at him and said, "Don't be a sycophant, if you have any questions, ask them directly." ”Tang Ruowang said: "I can mention it, but the general is not allowed to call me stupid anymore, I am originally a mortal, compared to the general, of course" Wang Shuo interrupted him: "Okay, you say, I don't say that you are stupid." ”Tang Ruowang said at this time: "According to the method said by the general, this hot air balloon should be able to fly."
However, I don't understand how to control the direction in the sky after it flies If it relies on the wind, then it will run wherever the wind blows, if we want to enter Beijing from the south, but the north wind blows at this time, then we won't let the wind blow farther and farther away from Beijing" Looking at Wang Shuo's expression, Tang Ruowang knew that he had asked another stupid question, and hurriedly put his index finger to his mouth to remind Wang Shuo not to scold him.Wang Shuo finally swallowed the word "stupid" that had reached his mouth, and then said: "You have to wait until the north wind blows to go out, you won't wait for the south wind to blow before the hot air balloon is raised" Tang Ruowang still didn't understand, and asked: "Even if you wait until the south wind blows, how do you stay in the air For example, you sat in this hot air balloon to the center of Beijing, and you wanted to throw the fire down, but at this time, the wind was strong, and you continued to run north, how could you burn the food of the Qing army" Wang Shuo praised Tang Ruowang with a thumbs up: " You are indeed smarter than Lao Wu, he can't think of this problem" Wu Langxi was directly expressionless, ignoring this sentence.Your head is a machine designed to think.What Tang Ruowang said is so right, you are sent by God, we are mortals, you are immortals, we thought of it, you thought of it earlier, I didn't earn you to scold me for being stupid Sure enough, Wang Shuo will come up with a plan to solve this problem in the next step.He said: "Have you ever seen a boat running in the sea, a boat walking in the water, a hot air balloon walking in the air, all the same, but the medium is different."
The boat is floating on the water, and the hot air balloon is floating in the air.The boat has a way to control the direction and go wherever it wants, and of course the hot air balloon can do it too. ”Tang Ruowang understood this time, not because he understood how to control the hot air balloon, but because he understood why Wu Langxi didn't ask anything.It's too complicated, how can they mortals make trouble to understand what the general says to do, don't humiliate yourself, let him scold him for being "stupid" and listen to Wang Shuo continue: "Isn't the chain drive now applied to practice" At that time, there was no rubber, and the belt made of cowhide could not transmit greater and more accurate work, so the chain and gear crankset transmission were widely used, not as it is now, only used on bicycles and motorcycles
