Chapter 539 Kongming Lantern

Wang Kuang took the speed from Wang Linbo's personal soldiers, demonstrated it again, and explained the truth that he had just told Wang Linbo. Old Man Xu lowered his head and thought, first with his brows tightened, then slowly stretched out, with a smile on his face, and it became thicker and thicker. After a while, he raised his head: "Well, this method should work. If you want the speed blades to keep turning, you can use the wheel slurry pedaling machine that you are using now to change it. I will call those old guys here. Everyone will think together, maybe it will be possible to create it." Seeing that after the ship was completed, they had no new goals. Old Man Xu, who was already a little lonely, suddenly became alive again. A brand new goal was placed in front of him, and he had a new pursuit. What else can you ask for in this life?

"Don't be busy, the Heavenly Secret is not this, I just told you that it is possible to go to heaven." After thinking roughly, it seems feasible to use human trampling, but Wang Kuang knew clearly that the speed of human trampling is not enough. If the speed is not enough, the lift is not enough. There is absolutely no way to send people to heaven. Even such sophisticated transmission methods in later generations cannot make a human trampling plane. How is it possible at this time?

The frequency of human pedaling is limiting. Even if the top sprinters are allowed to step on, the effect will not be achieved. Although the gearbox can be used to increase the speed, the most precise gear with the highest transmission efficiency is only about 95%. To achieve a speed of more than 1,000 revolutions per minute, at least four to six sets of gears are required, and the final loss of energy will exceed 20%. If it is the processing technology of Datang at this time, the loss of energy will be at least more than 40%. While increasing the speed, the pedaling force will increase accordingly.

If you want to drive a propeller to the sky, it must be at least three feet long. The farther you reach, the greater the resistance torque you bring to the transmission shaft. Therefore, theoretically speaking, manpower is feasible, but the premise is that a guy with divine power can keep stomping on it without knowing how to keep stomping on it. This is impossible. A short-term high speed does not mean that he can have a long-term high speed. Anyone who has ridden a bicycle knows that a short-term sprint is OK, but if you want to ride it for a long time, you have to take it leisurely.

Even if all this is solved, what about the materials? Propeller materials are difficult to find, at least not at present. Helicopters are different from winged aircraft. If the aircraft propeller is broken, the aircraft can still be forced to glide and land with the pilot's superb skills. But when the helicopter is broken, it can only carry the onion back to perform free fall movement. So, gliding? It seems that another way? If the east is not bright, the west is bright, and there is one more way, and there will be more success. The difference is that gliding requires training, and hot balloons do not need to undergo any training. Solving the material problem of hot balloons is equivalent to solving the coating material problem of gliding wings.

When he heard that it was not a method of speed to go to heaven, Mr. Xu was at a loss. He could bring heavy objects to heaven with his own eyes. As long as the speed was enlarged a hundred times, the heavy objects it carried would naturally be enlarged a hundred times. In short, the larger the method, the more it could be withstand it. But Marquis Jian'an said that it was not used. Is there any other method?

Those who work in technology always have to find the bottom line. Wang Kuang is worried that if he is gone, the old men can't let go of the idea of ​​flying cars and put their energy there. It would be a waste. So he didn't bother to tell Mr. Xu about the middle joint. As he said, Wang Linbo and Xu Guoxu were confused and understood nothing, but they didn't care. They only care whether they could go to heaven in the end. How could Wang Kuang tinker with them in the middle was too lazy to bother with that leisure.

Old Man Xu understood that because there was a precedent for the paddle wheel pedaling device in the building boat, Wang Kuang finished speaking, he knew the key point in the middle. It was really not as Wang Kuang expected. When Old Man Xu said that Wang Kuang didn't use the big speed, he really felt that no matter what Wang Kuang said, he wanted to try the big speed, but now he completely gave up this idea.

"Has Mr. Xu let the Kongming Lantern go?" Wang Kuang saw that Old Man Xu had really given up the idea of ​​a big speed car when he made an appointment, so he mentioned it.

"Let me go, I'll let you go every year." Old Man Xu seemed to remember something, a little sad, but he was shocked immediately, and he was very happy: "Ah, I know, I know." He danced happily, jumped to the bamboo craftsman, gave a few instructions, and then ran back to the back of the boat.

Xu Guoxu posted: "This old man is really interesting. If he hadn't been old, he wouldn't have been able to withstand the storms on the sea. I really wanted to persuade him to go out to sea with him. There is such an interesting person on the boat, so I can laugh more. Look at him, when he talks about Kongming lanterns, he completely forgot about going to heaven. He is really the old naughty boy you are in Erlang. Now he is still childlike, and if he has fun, he will forget the serious business."

Wang Kuang knew that Old Man Xu should have gone to get the cotton paper paste. The windows on the boat were carved and then covered with cotton paper. There were two layers, the outer layer was wooden boards or bamboo curtains to block the rain, and the inner layer was pasted with paper, which could transmit light and block the vicious sun in hot weather. When there was no rain, the outer layer would be raised, so that the room would not be dim and unclear.

Sure enough, not long after, Old Man Xu brought out a pile of cotton paper, and followed another old man happily, holding a small bucket in his hand. No need to guess, there must be no doubt that it was a mess. The old man should be responsible for the work of cladding. Old Man Xu must have gone to tell him about the affairs of heaven, so he followed him happily. Anyway, they didn't have to do the work on the boat, so they were just worried about being there.

When they got closer, the bamboo craftsman also finished the work assigned by Old Man Xu, and it was just a skeleton of the Kongming lantern, which was tied with a thin bamboo wire as thin as a needle. This did not need to be very reliable. As long as it could hold on to the paper and have a shape and outline. However, this skeleton is not small, more than half a person tall, and it is more than twice as big as the Kongming lantern placed on the Shangyuan Festival in various places every year. Wang Kuang saw that the lowest circle of the skeleton was obviously made of thicker bamboo strips, and three thin ropes were used to hang a bamboo joint that was about one inch long, and there was also a bamboo section under the bamboo joint.

"I have seen Marquis Jian'an, Marquis Jian'an is here. I said a few days ago that Marquis Jian'an will definitely bring us surprises when Marquis Jian'an comes. When Old Man Xu just told someone that he could go to heaven, he didn't believe it at first. Later, Old Man Xu said that it was Marquis Jian'an. Since Marquis Jian'an said it, it would be 80% possible." Later, the old man nagged more than Old Man Xu, and he helped Old Man Xu to make paper while making a fuss.

"Old Chun is still stronger. He ran over so far away and didn't pant." The old man's original name was not many people, but everyone called him Old Chun, just because he was so old this year, he always ran to the yard. I heard that he accidentally made a little lady in the yard two years ago. At first, he didn't believe it, but when the baby was born, his eyebrows and eyes grew up, he looked like him no matter how he looked. Therefore, he redeemed the little lady home, which was also a child from old age. From then on, Old Chun's name became more and more famous, and even Wang Kuang, who was far away in Chang'an, heard about this.

"Oh, it's true that you are Chun Lao? Tsk tsk, I didn't say anything, how did Chun Lao take care of it? Let's talk about it. I took this prescription back to Chang'an and helped you sell it for a big price, but I agreed that I have to have a 20% tick." Xu Guoxu also heard that when he heard that the old man in front of him was Chun Lao, his unscrupulous businessman's character cultivated by Wang Kuang was revealed. With a keen sense of smell, he intuitively felt that this was a good way to make money. Among the old masters in the court, there were many children but not many, who wouldn't want to add one or two more? Besides, since he could have a child, it means that the function in that aspect was absolutely powerful, which was definitely a temptation for the old men who were old.

"You can't sell it if you know." Wang Kuang glared at him. Chun Lao, who grew up by the beach since childhood, only likes to eat the most. Oysters and sandworms are one. After arriving in Dongzhigang, because Fu came to the inn, he received the instructions from Wang Kuang and sent them wine and food every day. He became obsessed with taro loaches and had to eat a pot in a few days. These are things that nourish yin and kidneys. Eating like this every day is naturally much better than other old men.

"Why can't you sell money? It's their own business, and I just care about the prescription." Xu Guoxu said unwillingly: "Erlang, you don't know. Many people secretly look for someone. Yang went to ask the old god to ask for the prescription. Maybe they felt that it was nothing to say that kind of identity, and they were embarrassed to find the old god. Knowing that Erlang, you have a good relationship with the old god, then someone will definitely be able to see the old god, so they came to someone. Not only someone, but also many people from Xiao Liuzi asked for it." Xu's foodie is not stupid. Since he is a foodie, he also knows that this is definitely related to food. Moreover, Chun Lao is a person by the beach, so most of the food is related to the sea. So when Wang Kuang said that he couldn't sell it, he was even more sure.

"Let's just let you, but it's strange. Aren't you not greedy for money? Why did you become a lust in money all at once?"

"I'm going to use it." Xu Guoxu pursed his lips.

I think Chun Lao also got the information about Xu Guoxu's identity from Old Man Xu. After hearing what Xu Guoxu said, he said, "Since Commander Xu is useful, don't talk about whether he is not a money or not. Just write it down and give it to you." As he said, his hands did not stop. It is worthy of being specialized in his profession. In a while, a half-person tall man was tall, and the Kongming lantern that the two of them hugged was ready. At this time, the bamboo craftsman came over again and grabbed a handful of broken hemp and stuffed it into the bamboo tube on it. The ball of hemp should be soaked with tung oil. Wang Kuang was quick to hand and hurriedly stopped the old man Xu who was about to ignite the fire, and said to the bamboo craftsman: "Please use your wheel drill."

Wheel drill is a common tool used by carpenters. It is a wooden double-section wooden pole that can rotate each other. A flat-headed iron nail is nailed on the lower section, and the two sides are sharpened. Then a long wooden bow or bamboo bow tied with a rope and wrapped around the wooden pole below. Pushing and pulling back and forth can drill small holes on the wood and bamboo, and can be inserted into pins, especially bamboo that is not easy to make a falcon structure.

The bamboo craftsman ran back and took the wheels and came to the crawl. He didn't feel troublesome or tiring at all. His location was very close to Wang Kuang. He could hear clearly what Wang Kuang and others said while working. In addition, it was Jian'an Hou who asked him to do things, and he felt that his face was covered, not to mention that miracles might occur under his nose. Therefore, he was also very active and cooperative, and did not complain at all because it affected his job.

Under Wang Kuang's instructions, the bamboo craftsman drilled more than a dozen small holes under the bamboo joints that had been installed with hemp. This was to ventilate and make the air supply more sufficient. The hemp squid soaked with tung oil burned more vigorously, and the hot air produced can carry a larger weight.

Everything was ready, Old Man Xu insisted on supporting Kongming lantern himself. Anyway, this thing was not heavy, so Wang Kuang was allowed to do so. However, he asked the bamboo craftsman to saw the bamboo hanging below and poured half a section of water in. Xu Guoxu shouted, "How can he fly at such a heavy level?" After the shouting, he saw that Wang Kuang and Huang Da looked at him with a smile, and quickly covered his mouth. Just kidding, this was Erlang himself, so how could he not fly?

If the bamboo joints do not have a small hole in it, Wang Kuang really dares to add water. Whether the Kongming lantern takes off is not only related to its volume and weight, but also to the amount and speed of hot air (the lifting conditions mentioned in Du Niang are not completely correct, because it leaks the speed of a hot air and the volume of the Kongming lantern, only considering the weight. The larger the volume, the greater the lift brought by the density difference between the hot air and the surrounding air. If it is said in Du Niang, then the hot air balloon will definitely not be able to take off.). Only after increasing the combustion speed, Wang Kuang has the confidence to add water.

After Old Master Xu helped the Kongming lantern, he took the fire stick and lit Ma Xu. After waiting for about a cup of tea, Ma Xu saw that it was half burned. Old Master Xu relaxed his hand and saw Kongming lantern swaying and slowly rising into the air, rising faster and faster. In a short while, he drifted along the sea breeze to the outside sea. Old Man Xu and others dared to make Kongming lanterns now, because the current wind direction is blowing towards the sea. Even if the Kongming lantern falls, it will not fall into the crowd or the town, causing a disaster. Even in this shipyard, there are shavings everywhere and tung oil everywhere. If you are not careful, it is hard to say that everyone's hard work in the past two years will be destroyed, and it is hard to say whether everyone's lives can be protected.

"Okay, it's OK!" Old Man Xu and Old Chun held hands and jumped up on the deck. Xu Guoxu kept muttering: "Only Xuzhou officials set fire, but the people are not allowed to light the lights? Some family stomped their feet and were anxious, and they could stomped themselves vigorously?" He said that, he had no intention of discussing Old Man Xu. He was not such a person.

"Yes, in this way, it is indeed feasible, but there are still several problems that need to be solved. After all, the Great Kongming Lantern needs to be carried by people, so it cannot be so careless with paper. It must be able to withstand the strong and thick satin that the wind tear is tear-out, and it must not be leaky or light. This matter will be left to the inner government to solve." After the two old men calmed down, Wang Kuang then mentioned the difficulties that need to be faced and solved in making hot balloons. If there is no top silk in the inner government, there will be no other place to find it. And even if the inner government does not have it, the inner government has resources. Whoever spins the silk in various places is the best, and only the inner government can master the most comprehensively.

"Silk also needs to be brushed with tung oil or other waterproof oil waxes. In my opinion, Chun Lao solved this problem. After all, he is an expert in papering and is more proficient in this aspect than those present. The main thing is to find an oil wax that is not as tung oil as tung oil. Otherwise, if people are on it, the wind blows the flames on the lamp body and burns it, the trouble will be great."

Chun Lao smiled and patted his chest, saying, "No problem, this is wrapped on someone's body. I know that there is a kind of medicine juice. After being mixed into tung oil, the tung oil will not burn so easily. However, since I have to take advantage of others, I have to find a better medicine juice according to my opinion, so I will do it."

"There are several problems that may require the cooperation of others, including blower oil, etc.." Tung oil is flammable, but tung oil is also cured by wind. If it is used for a long time, the nozzle may be blocked. So Wang Kuang still needs to find oil. He comes to find oil, but the combustion device requires these old men. The viscosity of the oil extracted with oil is higher than that of water. Therefore, the atomization situation still needs to wait until the oil is found before the test is conducted. Wang Kuang is not so arrogant that he can remember how many oils are in the boiling point section. He can't remember the temperature and viscosity ratio even if he is most familiar with hydraulic oil and lubricating oil.

"No problem, the old guys are worried about having nothing to do in the future. Now that there is something new that keeps them busy, they can be so happy to sleep." Old Man Xu asked Wang Kuang again, "Why don't you call them all up?" The paddle wheel was at the bottom of the boat. Listening to Old Man Xu's tone, they should be busy debugging below.

Wang Kuang nodded, and Old Man Xu ran towards the tower, not running towards the stairs leading to the lower level not far ahead. Xu Guoxu pursed again: "This old man is crazy and can't even tell the direction." He always picks on Old Man Xu's thorns, but he was just preached by Old Man Xu, and he was not very balanced. He always wanted to see Old Man Xu look ugly once.

However, he was disappointed. Not long after Old Man Xu climbed up the tower, everyone heard Old Man Xu's shout from a trumpet-shaped tube not far in front of them: "Several old guys, hurry up and go to the deck. If there is something big or good, come on the speed, it's out of date!"

Huang Da then smiled and said to Xu Guoxu, "Stop being stunned? Haha." Among the people here, Xu Guoxu didn't know that the new building ship was equipped with a microphone. The principle was very simple, but it was just using the bamboo tube sound transmission principle plus the speaker resonance principle. When Wang Kuang told several old men, they understood it. However, Wang Kuang took a long time to make the old men half understand. Later, they gradually explored it and finally mastered it successfully.
