Zhang Huan's simple and simple request choked Zheng Hongming and rolled his eyes, thinking that this is a child who doesn't know where it came from, it seems to be a child's words, but whoever listens to it seems to blame us for not taking good care of us! But when he turned his head and looked at Jiang Tian again, he found that his immediate boss didn't seem to mean to reprimand him, so he estimated that this child's background was not small, so he couldn't bear the unhappiness in his heart and smiled awkwardly: "Where does this little boy say, although the place is simple, it can also shelter from the wind and rain." ”

Jiang Tian knew that Zheng Hongming must have misunderstood the meaning, so he stood up and explained: "Old Zheng, don't be like him, my student has been annoyed with me all the way, I just want to see how the warship was caused, if it weren't for his solid scientific foundation, I wouldn't want to take him out." ”

Wu Yuan and Liu Baokai rolled their eyes in unison, and Cheng Dù, who had uniform movements, looked like a fellow disciple. These two insiders thought to themselves, that is, your old man dares to say this, and the prince is a scientific idiot, let alone your misdemeanor. Besides, if the prince hadn't come with him, we wouldn't have had to make so many troubles.

Others don't know what the two of them are talking about, but those researchers obviously don't see it that way, you must know that these people are also experts in the field of shipbuilding, although most of them are halfway monks, but when it comes to theoretical knowledge, it is also a world-class level, because even in Europe now, shipbuilding technology is mostly at the level of experience accumulation and oral transmission, otherwise the "artificial reef" that Gustav built with all his strength will not become a laughing stock in history. Therefore, when these people listened to Jiang Tian's crash course theory, they didn't look at the experience of shipbuilding much, but their vision of the entire shipbuilding industry has been improved to a higher level. Now there will be a hairy boy, who is rated as a solid apprentice by Jiang Tian, and of course he will not be convinced in the hearts of these science and engineering men.

But if you are not convinced, you can't attack it now, according to the rules, this reception banquet is indispensable, so you have to finish eating anything. When he arrived at this place, Jiang Tian no longer had to worry about some rules in the officialdom, and grandly counted Xinyue and Meng Daya in the banquet, but he still had to consider the factors of male and female defense and opened a separate room. Don't look at these researchers who are not interested in the little-known Zhang Huan, but Xinyue's name has definitely been heard of, these talented women have been concerned, and there is absolutely only one talented woman who is good at science, to say that the most popular thing for science and engineering men is to have a confidant who understands science, that is to say, Jiang Tian's state is the most enviable to them.

But these are not problems, at the moment, Zheng Hongming's main concern is not Xinyue's identity, but his research has encountered a key problem, so that at the dinner table, he can't wait to ask Jiang Tian for advice: "I don't know how many days the adults can come this time?" ”

Jiang Tian, who was gnawing on the crab, wiped his hands unfinished and wiped his mouth clean: "I received your letter and know that you have encountered a little problem, so this time I am mainly here to supervise the construction of warships, and I will not go anywhere for at least two months." ”

"That's good......" Zheng Hongming's heart finally let go of a little: "In fact, I have to trouble adults every time, and I ...... in my humble heart."

Seeing that he was a little distracted, Jiang Tian knew that his little self-esteem was a little too much to let go, but people all over the world were staring at them, so as to see what these people with very high fortunes were capable of. Besides, many people who are interested in going to sea to do business are also staring at the new sailing ships of the Institute, if there can really be a merchant ship that is faster than all the warships, then the risk of encountering pirates at sea can be minimized.

So Jiang Tian didn't care about the other party's expression, and continued to pick up a crab leg and cut it with pliers: "You don't have to be polite to me, after all, this type of ship was proposed by me, but I have other official duties, so I have handed over the main work to you, and now it's just that I should do my duty." ”

Zhang Huan, who is also eating crabs, is much more elegant than Jiang Tian, this prince is not the kind of pampered master, and he doesn't need to be served to eat this kind of seafood. But the action of tasting at a glance is like those gentlemen in Jiangnan eating hairy crabs. He ate crab meat in his mouth, but his ears were supported to listen to their conversation, as for the difficulty of developing because of the relatively novel ship type, he had also heard of the most important reason why he took the initiative to come this time, he wanted to see how Jiang Tian, who has always used science to solve various problems, created a miracle this time.

In fact, he will be disappointed this time, this is not the development of telescopes or movable type printing, the difficulty of shipbuilding is by no means the kind of primary industry that fights pettily, even if all kinds of materials in the research institute are well prepared, it does not mean that you can get a good ship by stacking these materials on the slipway casually, so even if Jiang Tian has more knowledge than others, he cannot help the craftsmen solve the problems in the process, at most it is to put forward some advanced ship types for everyone's reference. Due to the tight time, Jiang Tian began to enter the working state after eating, and asked Zheng Hongming to lead everyone into the dry dock.

"My lord, this is the corvette you designed, according to the results of our test of the model, the aspect ratio is set to 1:6, the waterline is about eighty meters long, there are two masts, for the sake of insurance, the whole ship has a total of eight gun emplacements, one of eight heads and one at the end of the left and right cross, the estimated speed can reach eighteen kilometers (about ten knots), because it is extremely slender and long, in order to stabilize the transverse dìng, and use the keel designed by you, my lord, it can be regarded as a warship with light and dexterous advance and retreat freely and powerful firepower, but ......"

Jiang Tian looked at the hull that was basically suspended, the sharpened shear bow side was a little floating, this is to prevent the bow from going up the waves, the square tail is set up with a two-story stern, and the stern design is also to leave enough maneuver space for the two main masts, although the keel is the first time to appear in this time and space, but the principle is not complicated, so it is not very difficult to load the ship, and the floating freeboard itself has a certain anti-roll effect, and the eight guns arranged in the middle of the ship are arranged in a staggered way, This is because the width of Class A is not enough to be placed side by side, but its firepower has surpassed that of the Wugong ship and the Cangshan ship equipped by the current naval army, and the speed is even worse than the opponent's horse. It can be said that as long as this type of frigate is officially delivered, then now those small and medium-sized warships in the navy can be decommissioned.

"Your letter says that in order to strengthen the longitudinal strength, I arranged a longitudinal girder under the main deck to cause a high center of gravity, and the large-scale model was found to have a lower turning radius than expected during sea trials in the water, and the turning was too sharp and there was a danger of overturning? And you are worried that the hull is too narrow, and the strength of the hull will be affected by the vibration of the artillery! ”

Zheng Hongming nodded deeply with a group of researchers, in their opinion, although the firearms loaded on this ship are sharp, but for a panacea ship that often goes to sea alone to detect smuggling and thieves, guard routes, and act as a pioneer and chaser in large-scale naval battles, the narrow hull is not conducive to hand-to-hand combat at sea, and the fragile hull after being shot is not necessarily as solid as the smaller Cangshan ship. From a practical point of view, their concerns were indeed justified, for this ship, which was only one meter wide at the waterline, it was indeed very thin and fragile, and the loading capacity was less than that of the old type, and its only advantage was speed.

Liu Baokai and Wu Yuan, who were standing on the side, couldn't say anything at this time except for staring at the ship in a daze, only Zhang Huan touched this and looked at that, with an excited face: "Sir, I remember that you once said that naval warfare will gradually be dominated by artillery bombardment in the future, when you designed this ship, did you consider that it is mainly based on artillery warfare, so it is so slender?" ”

Jiang Tian nodded, thinking that this kid had finally wasted my saliva all the way, and saw my original design intention at a glance: "The problem of longitudinal strength cannot be weakened, and this is only a ship type used for testing, and a large turning radius is also a relative problem, as for the problem that the artillery vibration may cause structural instability, there is no need to worry about it, this ship cannot be equipped with large artillery, and even the main equipment is rapid-fire small-caliber guns, even if you encounter an enemy who wants to rely on hand-to-hand combat, you can calmly suppress it with firepower, The only drawback is that you don't really see it. That's because the boat is relatively small, so it can be easily damaged in bad weather, and because the small cabin also affects its self-sustaining. ”

Now everyone doesn't understand, since you know its advantages and disadvantages so well, why didn't you bring it up in the first place? Instead, wait until it's almost finished? Is it really because of the high nature of the experiment, so it deliberately let everyone practice?

Jiang Tian looked at these people and smiled slightly: "I want to unify many small and medium-sized ship types into this kind of clipper ship, which is itself to reduce the pressure on logistics, reduce the cost of maintenance, and also bear the effect of testing modular cabins, but before the steel keel is built, only a part of the displacement can be spent on strengthening the structural strength." However, in the future, most of its missions will focus on combating smuggling, escorting ships, etc., and if it encounters a lone pirate ship, it will not be inferior in firepower suppression and capture of enemy ships or long-distance artillery battles. If you encounter a tough enemy, you can also escape with speed. So I am not worried about its construction, and it will be possible to compensate for these shortcomings by building a larger ship in the future, but the point is that you have written to me that the mast of this ship has not yet arrived, and that the iron ribs that increase the strength are more prone to oxidation than expected. ”

What Jiang Tian said is the real problem of this ship, after any new technology comes out, there will always be someone to confirm its value. The length-to-width ratio of later warships was rarely lower than 1:7, and now Chinese ships rarely exceed 1:3, and it is certainly a lot more stable to sit up, but in the face of Western warships, it is often difficult to have great results because of their own clumsiness and scarcity of gun positions.

"If we can't solve the problem of splicing masts, then in the future we will be constrained by wood and will not be able to build ships, and the problem of angle iron oxidation on the ribs can now be solved by galvanizing the surface of guò." Saying that, Jiang Tian beckoned to Xinyue, and she took out a drawing from the bamboo tube she was carrying with her: "You see, as for the protection of the broadside artillery battle, I have made some deliberations on the way here, why does the ship have to put the all-through keel on the bottom of the ship?" The bottom of the ship can be supported by a finer mesh structure, and the multiple dragon tendons near the waterline are thickened and enlarged, so that even if it is shelled by the enemy, unless it is an armor-piercing shell from a heavy artillery, the thicker wall panels on both sides can not only strengthen the bullet resistance of the ship's side, but also reduce the center of gravity. ”

A group of people around the drawings for a long time feel that this method is feasible, in the weight reduction at the same time can also strengthen the structure, the key is that the original most expensive wood keel has been changed to a cage, so that the cost of shipbuilding further reduced, but this change can ensure that the bottom is strong but no one is sure.

Zhang Huan also squeezed into the crowd and looked at the drawing, he didn't know when Jiang Tian drew the drawing, but he saw the trick at a glance: "Sir, this is to disperse the power concentrated in one point across the whole ship!" But didn't you say that the all-pass keel is an important invention in our country, and this technology cannot be mastered in Europe, but now it needs to be innovated? ”

In a short sentence, the researchers, who had already looked down on this child, were impressed, and his question was whether the use of a more novel interior design on an already unconventional ship would ensure the safety of the test? As we all know, because China's maritime development has not stopped before the Ming Dynasty, by the early Ming Dynasty China had mastered many world-leading shipbuilding technologies, such as rudders, shoulksails, water tanks and all-through keels. These technologies have enabled China to build giant ships like treasure ships out of wood very early, but the disadvantage is that the pursuit of speed has not been high, and the loss of technology caused by the sea ban makes people feel that at the end of the Ming Dynasty, the level of European shipbuilding has caught up with China. In fact, Jiang Tian wanted to change the shortcomings of the traditional ship type that was too slow, and he was worried that wood would limit the development of the shipbuilding industry, so he copied the cage-shaped keel structure in advance. Like splicing masts, it can circumvent the limitations of wood, but the requirements for craftsmanship are higher.

"In short, this ship does not need to be changed, and the sea trials will be carried out immediately after the outfitting is completed, and the masts will be changed to the stock masts if they can't be spliced, and the number of sea trials will be mainly used for the construction of the next test ship." Jiang Tian saw that everyone was focused on the drawings, and quickly set the tone: "As for this new design, you will send some researchers who will not affect the progress of the test to conduct pre-research. ”

After Zheng Hongming finished arranging the work, the pervert @ wolf, who had not spoken, smacked his lips and whispered: "Such an expensive ship is so wasted if it is not good?" ”

It's not just the pervert @ wolf, most people have similar thoughts, to put it bluntly, is this ship test a bit wasted by Jiang Tian.

Jiang Tian looked at the people around him, and then shook his head regretfully: "It's a shame that I taught you all by me, and I don't want to think about how we can get the exact scientific research numbers before there is no credible mathematical formula to calculate?" It can only be achieved by exhaustive means, so you know why His Majesty has allocated so much money. ”

Zhang Huan was stunned for a moment when he heard this: "So...... Majesty also knows how to build ships? ”

"I don't understand!" Jiang Tian said with certainty: "But he knows that the cost of developing weapons is amazing, and it is not necessary to spend money to get the desired results, but without spending money, he will not get anything." ”

When everyone heard this, they suddenly felt that the emperor and his junior brother were simply not Chinese, these two people thought differently from everyone, and they were so concerned about some things that could not see the results at all, in fact, the old ships left by the ancestors were not impossible to fight, why were they so anxious to renew, and even did all kinds of things that others had not seen. Even if they see the Europeans as China's future enemies, according to their own calculations, it will take 100 years at the earliest to have the ability to threaten China.

With this question, no one asked, because even if Jiang Tian asked, he would smile incomprehensibly, and said that the last sentence should not be revealed, even if it was perfunctory. But since His Majesty the Emperor has supported it, then the frigate that was originally in a semi-suspended work began to speed up the construction, just like Jiang Tian said, this ship itself is more for experimental purposes, and it will not necessarily be delivered to the military in the future, so there is no need to worry about its service life, the first task is to test whether the clipper type can be qualified for the work of small and medium-sized warships. The second is to summarize the construction technology of the new ship, which can be used in the follow-up work of the military shipyard.

In addition to supervising the progress of shipbuilding every day, he also had to open a small stove for those researchers at night to explain more physics knowledge, but this work was completed for Jiang Tian by someone with higher interest, whenever those researchers whose eyes were above the top looked at Zhang Huan, who was not much higher than the table on the podium, explained the three laws of physics at a glance, and explained the impact of various resistances on the ship, these people had a feeling of insanity. However, they also understood the reason why Jiang Tian valued this kid so much, when it came to the solid Cheng dù of physics, his gang was really not qualified.

Even if he didn't have to give a lecture in person, Jiang Tian was not idle at night, but worked hard with Xinyue Wu Yuan and them day and night to revise the design drawings of the new ship, and went to the dock every day to have in-depth exchanges with those craftsmen, so as to know that in actual production, what kind of design would meet the realistic technical conditions. In order to make full use of the resources of the research institute, the original ship is still in the final outfitting, and the newly designed ship has been built on another slipway, this time the craftsmen saw for the first time that the all-through keel has been cut to one-third of the original, and the dragon tendons and ribs are too strong revolutionary design, Jiang Tian gave this structure a figurative name - birdcage configuration!
