About Me

So Tsai Chi, who knew very well, immediately said that Guan Tong could arrange for these families to live in Huang County for a longer period of time. But Guan Chengjian Cai Ji received the hostage also happily invited the people on board a tour, but also to show the strength of their own. To tell the truth, the ships brought by Guan Cheng were far from the warships in Cai Ji's previous impression. At first glance, it looks like three fishing boats. However, the three-masted sailboat, which claims to be able to hold fifty or sixty people, is quite large. It is about twenty meters long and seven meters wide. Its deck is also equipped with eight wooden winches that operate sails, anchors and fishing nets. According to Guan Cheng's introduction, this kind of winch is called "vehicle barrel", which was refitted by themselves after they robbed the stick tribute ship. In addition, there is a one-man-high rudder tower on the stern deck, each with two lounges, in which there are tables and incense burners, apparently left by the three Han tribute envoys. As far as the appearance is concerned, this boat is very similar to the old Hong Kong fishing boat that Cai Ji had seen in the film before. The only difference is the cabin and the sails. Obviously, watertight compartment structure has not been invented in this era. The hull under the deck was almost full length, with only two rooms at the bow and two at the stern to store food and fresh water. As for the other two smaller sailboats, Guan Cheng admitted that there was no room under the deck. As for the sails, they are also different from the signboard Chinese sails in Cai Ji's impression. The sails of these three ships are made of cloth, suspended by herringbone masts and supported on the sails without bamboo poles. Hasn't China invented hard sails at this time? No, according to historical records,ultrasonic spray nozzle, hard sails have appeared in the south of the Eastern Han Dynasty. Or has the hard sail not been popularized in the north? Cai Ji frowned in puzzlement. Of course, this is also possible, after all, at the same time, Rome, Egypt and other countries are also using soft sails. No, it's more accurate to say that because of the lack of bamboo, Europe,ultrasonic dispersing machine, the Middle East and other countries used soft sails for centuries. China, on the other hand, used local materials to invent its signature patent, the hard sail. Compared with the soft sail, the Chinese style hard sail has high wind efficiency; it can rotate around the mast and face the wind. Hard sails are lighter, because they have supporting bones, so the quality requirements of sails are very low, even if there are many holes, it does not matter. Therefore, as far as shipbuilding technology is concerned, ancient China has always been in the forefront of the world. It was not until Europeans developed full sail, that is, all masts were equipped with square sails, but the lower part of the mizzen mast had gaff fore-and-aft sails, that they surpassed China in sailing technology. But for smaller boats, hard sails are still the best option. But when Cai Ji lowers his head to meditate, Ultrasonic nano dispersion ,ultrasonic emulsifying machine, Guan Cheng on one side looks a little nervous. Afraid of Fu Jun's dislike, he asked tentatively, "Master, is there anything wrong with the ship?" Cai Ji was in charge of a "master" a call, immediately back to God. In other words, this is the first time that someone called himself master besides Zhang Qing and other Cai Fu generals. So Cai Ji immediately acquiesced in Guan Cheng's change of words and readily answered, "This boat is not bad. It's quite big.". But Ji had seen a bigger ship than this in the capital. Why don't we draw the boat here. Please also manage the general to help this house to see see, can draw lessons from refit the warship. As soon as Guan Cheng heard that Cai Ji was going to tell him how to build a ship, he was somewhat disapproving. However, on the surface, he was very attentive to ask people to bring pen and ink, and even provided a clean piece of white cloth for the little Cai Fujun to paint. Cai Ji took the brush, closed his eyes, recalled the many ancient Chinese sailing boats he had seen in his previous life, and then calmly began to paint. Because Cai Ji had studied Chinese painting in school in the last generation, a lifelike four-masted sailing boat jumped onto the cloth in a short time. Guan Cheng and others were amazed. Standing beside Cai Ji, tardif stroked his long beard and nodded, "This is a sail painted by Xiaofu Jun.". Indeed, official ships often use sails. "Sail?" Cai Ji turned his head in puzzlement and asked. The sail is the sail on the painting. The sails of the three ships at the moment are called cloth sails, while the sails with bamboo on them are called sails. Tardif further explained. After hearing this, Cai Ji realized that the Eastern Han Dynasty was still in the period of alternating use of soft and hard sails, and hard sails were called sails in this era. Fortunately, I didn't say anything just now that I had a new invention on a whim. Otherwise, it will be a big loss of face. But just as Cai Ji was secretly rejoicing, Guan Cheng craned his neck and pointed to another ship without sail and deck on the painting and asked, "Master, what kind of ship is this?"? Why is it separated like this? Isn't it inconvenient for people to sit in the boat and paddle? "This is what the inside of the sailboat looks like in the picture above.". This mansion also asked so at that time. But the boatman told me that this method was called watertight compartment, which was to divide the cabin into eight compartments that were not connected to each other. Because of the tight separation between cabins, even if one or two cabins are damaged and flooded during navigation, the water will not flow to other cabins. As long as the cargo in the flooded cabin is removed, the damage can be repaired without affecting the ship's continued navigation. If there is too much water, the ship can not support, but also need to abandon the cargo, reduce the load, the ship will not sink to the bottom of the sea quickly. Cai Ji explained carefully. However, Cai Ji did not make a mistake this time. After listening to her explanation, Guan Cheng immediately praised her again and again, saying, "Not bad, not bad.". That's a good idea. No wonder the official ship is so strong, so there is such a clever plan. This bulkhead looks like ribs piece by piece. If you build a ship according to this picture, you don't even need to add ribs. Master, please give this picture at the end. Will be able to build a warship for the tetrarch according to this picture at the end. "This picture was originally drawn for the general.". "I'm afraid that if I don't paint well, I'll mislead my children." Cai Ji said and generously handed the picture to Guan Cheng. After receiving the drawings, Guan beamed and said, "The master draws much better than the carpenter in the water village.". We know what it is when we see it. When Cai Ji heard Guan Cheng compare himself with the carpenter, he was not angry. Instead, he asked, "Are there any craftsmen who build ships in the water village?" "Yes.". The craftsmanship is very good. They built all these boats. Guan Cheng nodded and answered. That's very good. The government is planning to build a ship. With the help of Changguang Water Stronghold, we can get half the result with twice the effort. Cai Ji thought it was really sleepy and someone gave him a pillow. As soon as Guan Cheng heard that Cai Ji was planning to build a ship,ultrasonic welding transducer, he knew that he was going to expand the navy. So he quickly folded his fists and said, "Here.". At the end of this will repair a book, let the craftsmen came to the county government to wait for the tetrarch. 。 fycgsonic.com
