Jiang Tian took the opportunity of his impeachment to throw out a far-reaching plan for naval reform, but for the sake of balance, he also had to hand over a new weapon to arm the existing old ships, so that they could fight the so-called powerful Zheng pirates, or deter European merchant ships who liked to make cameo appearances as pirates when they had nothing to do. Jiang Tian thought about it, with the existing ships and training conditions, it could only be a superweapon that could fight against large ships and challenge more enemies than his own number, but fortunately, he did have such a thing in his inventory, and it was easy to manufacture and easy to equip on a large scale.

"I gave this thing a name - rocket artillery!" Jiang Tian wrote these three big characters on the blackboard.

The students at the bottom, you look at me, I look at you, they all think that Mr. Jiang is joking this time, and he patted his chest at the court meeting and said that he had a new weapon, but it turned out to be the homework of these students. Fortunately, Jiang Tian did not embarrass them, and only asked to be able to draw a simple diagram and explain the working principle. Besides, this kind of weapon was not new in the Ming Dynasty, the most famous ones such as the South Koreans said to be a swarm of bees invented by themselves, and the first sea-skimming anti-ship missile in human history - Jiaolong out of the water! Of course, these weapons belong to the most primitive state in Jiang Tian's eyes, but in this time and space, they are still beyond the reach of those newly developed countries in Europe, but this gap is already very small, especially when the barrel artillery begins to develop greatly, this kind of rocket weapon seems to be a little chicken, so Jiang Tian feels that since there is no big breakthrough in artillery for the time being, it is better to work rocket weapons.

This kind of thing has been mentioned in many travel novels, basically not much about the structure and the composition of the propellant, and when Jiang Tian really started to design, he found that the situation was much more difficult than he imagined, first of all, the shape of the rocket, the selection problem seems to be the simplest in the eyes of many people, after all, so many photos of rockets in later generations are full of Internet language and various military magazines, but for a layman, they will not understand why some rockets are short and thick and some are slender, why some have sharp heads and some are relatively round, It is not even understandable why some rockets have four large wings, while others are so small that they are almost invisible. These are just exterior shapes, and to make them involve the housing material, the engine, the ignition mechanism, the propellant, the guidance and stabilization system, the warhead, the fuze design, and so on...... Wait a minute......

Jiang Tian finally knew that he had caused trouble, and he could not devote himself to the work of rocket research and development as before, whether it was naval reform or daily official business, he needed to be personally asked by the prince Taibao, so he decided to try the real sense of the research institute system, although the existing personnel can only be selected from their own students, but if they can really complete this arduous work, it means that they can not only graduate from here, At the same time, it has also become the most professional R&D team in this time and space. In other words, it's their graduation project plus thesis defense.

Faced with such a complex and arduous task, Jiang Tian did not have too much difficulty in choosing a design for these immature guys from the perspective of use, and his students had to work hard to perfect the plan. Considering the existing technical level, the rocket can only be selected as a solid propellant, as for the shell because it has a certain level of processing, so it was decided to use a thin iron arrow body, and the head is equipped with a pointed cone fairing, in order to keep the flight lateral stability, Jiang Tianyuan wanted to refer to the design of the Hale rocket to install the inclined tail, and later considered that the oversized tail would have too high requirements for the launch site, and at the same time was not conducive to large-scale centralized launch, so it had to adopt a complex design, The whirring engine that is troublesome to make, simply put, is to install two built-in small rockets behind the warhead, and install a directional rod on the arrow body, the main rocket is ignited when launched, and the directional rod starts the initial rotation along the track on the launcher, because the power is limited, under the premise of ensuring a certain power of the warhead, the loss of thrust is as little as possible, so the slope of the track is not too large, when the rocket flies away from the launcher, the fuse ignites the spinning rocket, if there is a high-speed camera, You can see two flames that shoot backwards at an angle, and their effect is not only to accelerate the rotation of the projectile, but also to add a little thrust to the rocket. When the rocket in the sky to draw an arc to fly to the target, the optional delay fuze or impact fuze will begin to work, the working principle of these two things is also very simple, the delay fuse is an ordinary burn lead, how long the timing is used. The impact fuze is a little more troublesome, because the current level of machining is not enough to support such a complex thing, so Jiang Tian retreated and chose a very primitive design, that is, a few probes are installed on the fairing, once it touches the target or the ground, the probe will shatter a glass bottle in the warhead, and the sulfuric acid in the bottle will come out and ignite ** to complete the detonation, and the whole process will take only a few seconds, which is enough for the current war. In addition, in actual use, a delay fuse is generally used, whether it is bombarding ground targets or water targets, it is necessary to rely on a certain number to achieve a lethal effect, and a simple collision detonation is not too effective for killing battleships with rough skin and thick flesh.

Such a primitive rocket is a little more complicated than entertainment for modern people, but for researchers who see the design outline, it is definitely shocking. At first, everyone thought that Jiang Tian was just an improvement on the original firearms in the Ming army, but no one expected that it would be such an advanced militaristic heavy weapon, and because Jiang Tian could not believe in the shooting accuracy of the new rocket, he designed a twelve-mounted launch frame used on the ship. So much so that Liu Baokai, who was familiar with cavalry operations, trembled uncontrollably after seeing the parameters, if the cavalry encountered this kind of weapon when the cavalry group assaulted, it would be a catastrophe.

In order to reduce the difficulty of development, Jiang Tian decided to make a light version of a hundred millimeter caliber first, this diameter rocket can be lifted by a single soldier without much effort, and two people can complete the loading, even if there is no launch pad when necessary, a temporary launch pad can be set up only by an inclined mound, which will affect the accuracy. In addition, the support strength of the thin iron sheet is likely to not be able to ensure the stability of larger diameter rockets, which can be regarded as a helpless compromise. Because of the previous experience in product development, the current Academy of Sciences is not as confused as at the beginning when it receives Jiang Tian's development task, whether it is a standardized development process or a summary of work after various tests, there are preliminary specifications. And the researchers at all levels, who have become more and more experienced, do not feel how difficult this task is, and it is almost a patchwork of existing things, and then they combine an epoch-making new weapon, of course, many people are depressed to find out why they did not think of such a brilliant idea. There is a reason why they can't imagine that the normal scientific development in this world has a context, and very few new things are given a certain military use from the day they are born, and it is not until later that scientific development becomes a means of foreign conquest by hegemonic countries, and the military gradually attaches importance to the impact of new technologies on military transformation. Even in later generations, the United States simply set up a future weapons research center, which is specially responsible for pre-researching new technologies and studying their main uses, and the famous Internet came from the idea of this organization, which is also an important means for the United States to maintain its military leadership after the war. The Academy of Sciences in this time and space is a bit similar to this organization, although there is still a long difference in organizational structure and work efficiency, but because Jiang Tian has advanced knowledge, the final effect is not worse than the other party, at least when Jiang Tian is alive, this will always be the world's leading research and development center.

Since the research institute and researchers have the initial ability to work, Jiang Tian no longer cares about the specific work, what difficult problems are encountered If Jiang Tian has already taught the knowledge, he also encourages the other party to find a way to solve it by himself, and there are not too many things that require him to personally go out, so he turned his main energy back to the work of propaganda, after all, even if there is no rocket artillery, the army of the Chinese Dynasty also has the deterrent power of being proud of the world, and the fleet of the navy is not something that can be built in a day. Even if it is built and trained to be a qualified sailor, I don't know how much time it will take. And this qiē must be established under the condition of social stability and economic recovery, so that the imperial court can have enough resources to build a modern and advanced army. The priority is not precisely the development of new weapons, but the reform of the social structure in order to increase productivity. The first thing to do in reforming society is to restore the population as much as possible.

"This Liu Qiao'er was originally a rural village girl, and the Zhao family in the neighboring village was free to set up a baby kiss, how could the young Qiao'er leave her hometown with her family for refuge......" Behind the desk, Mr. Liu began to talk about this new book, although it is not a heroic hero, nor is it a child's love, but because the characters in this book are very close to the identity of the audience, it is more attractive to ordinary people. You must know that Mr. Liu has not been very happy in recent times, and has been robbed of a lot of listeners by cross talk, and the long storytelling is not as short and concise as the cross talk jokes, so the update of the new book is naturally not as frequent as the cross talk, if it is not for the capital, only this teahouse can hear cross talk, otherwise Mr. Liu may have a sense of crisis. At this time, Jiang Tian found him and gave him some new stories to arrange into a storyteller, of course, the intention of this was to publicize various decrees of the imperial court, and Mr. Liu, who had no new books, naturally agreed to do his best, and promised to spread these stories in the circle of storytellers.

The new "Liu Qiao'er" is of course different from later generations, and the heroine here has an independent and pungent personality because of the experience of fleeing, which is quite different from traditional Chinese women. And the actor Zhao Zhu was forced to join the army to defend his family and defend the country, and only saw his fiancée for the first time after he was demobilized and returned home. But the meaning it expresses is enough to be regarded as earth-shattering, and for a long time, people had the impression that only those who were lowly and despised would be so open. Even if there are some stories that have private lifelong love plots, most of them are elegant and elegant things of the sons and ladies of large families, such as Cui Yingying in "The Legend of the West Chamber", for ordinary people, weddings and funerals are naturally the words of the matchmaker of their parents. And one of the heroes and heroines in the play is a peasant, and the other is simply a demobilized soldier of the New Army. Therefore, as soon as this story came out, it immediately set off a frenzy of criticism of the "unhealthy trend", and those who were already dissatisfied with the new "Marriage Law" immediately stood up and strongly condemned it. In this process, although the Confucian family in Qufu wanted to keep a low profile, they were still brought out to refute these "fallacies" with the righteousness of Confucius and Mencius. Then someone turned out that these stories were from the Jiang Mansion in the capital, and now people finally found the target of the attack, and for a while, the verbal and written criticism of Jiang Tian's bad customs was endless.

In the whirlpool of public opinion, Jiang Tian did not look frightened or angry, what should he do every day, in addition to regularly paying attention to the development process, he continued to teach the remaining students, and then guided the business of the band. And recently, because Yuzhu was pregnant, the supernumerary Hongyun naturally squeezed into this small circle. Xinyue just shook her head and didn't say anything about this, because she knew that Hongyun's purpose was to improve her influence in **, and she didn't really want to become Lord Jiang's concubine, so she didn't exclude her too much. But Linglong obviously doesn't think so, this girl is not rightly named, she has neither the ability to work in Xinyue, nor the qualifications of the quiet sisters, if it weren't for the way of music and some achievements, I'm afraid I wouldn't be able to deal with it a long time ago. But there is still a red cloud to compete with her for favor, she can't be as naked @ naked as some girls ** Jiang Tian, in her heart there is a reserve that everyone used to be beautiful, in the words of later generations, she is proud enough but not coquettish, and she can't attract the attention of a dull man at all, so her hostility towards Hongyun is also the greatest.

As for whether she really likes Jiang Tian, she doesn't know this, after all, she has seen too much drama on the spot, and she is really numb to this kind of thing. She only knew that she was as impressed by Jiang Tian's knowledge as Tongyue, but she was not as obsessed as Xinyue, whenever she saw Youlan's show-off expression, she was a little uncomfortable, she always felt that she was more attractive than these two sisters, but she couldn't get someone's favor. This feeling is actually the hazy feeling before falling in love, but the person concerned doesn't know it.

Jiang Tian didn't know about such a troublesome thing, he just found that when he came to the band to guide recently, Linglong always targeted him intentionally or unintentionally, although it was not a matter of principle, but it just made people feel uncomfortable. Fortunately, compared with the first time we met, Linglong's temper finally restrained a lot, so I didn't let Master Jiang go away directly, but the other party regained his previous style. Jiang Tian soon discovered that not only was Linglong's state wrong, but Xiyun, a girl who didn't like to talk very much recently. The little girl who had regained a little bit of vigor began to become depressed again, whenever Jiang Tian returned to the house, she would not jump out to greet her like before, even if she still liked to stick to Jiang Tian, but she just sat quietly and depressed.

"What's going on? Who upset my sister? Come, sue my brother, I'll give you anger. ”

No matter how Jiang Tian asked, the little girl just didn't speak, and her concern for his life was increasing day by day, and she would occasionally linger to look at the bedroom that only the quiet sisters had set foot in. Once it was night, as long as there were quiet sisters, she would immediately hide far away.

"What do you think she's doing?" Jiang Tian, who couldn't figure it out, had to find someone who understood to ask, and the person who understood in his eyes was Xinyue.

For this question, Xinyue's pretty face couldn't help but blush, in fact, she couldn't extricate herself from being in the game, why others liked Jiang Tian She didn't know, but she herself was definitely conquered by the rich knowledge and respect for women's mind, she knew that this was by no means fanatical love, but besides Jiang Tian, who else would treat these ** women as a complete and dignified person, just this is enough for her to respect each other for a lifetime. It's a pity that people just think of themselves as female apprentices.

"Xiyun, ah......" Xinyue hesitated: "I think it's because I'm not feeling well, I'll go and ask Lang Zhong to take a look." ”

Although Xinyue said it well, Jiang Tian, who was knowledgeable, guessed from her twisted expression in an instant what kind of "physical discomfort" it was! Thinking of this, he was not too surprised, after all, the nutritional imbalance of ancient people did not develop as fast as modern people, and it was not too strict to have "discomfort" symptoms so late, so he muttered to himself: "So that's the case, this girl and I are still hiding, why don't she say how I guessed it......"

Xinyue heard him mutter, knowing that Jiang Tian had already guessed a rough idea, but she didn't expect that the erudite Lord Jiang would even know so much about women, I think it was known to the Guò Qingyou sisters. But there is still an answer in his heart that he hasn't said, that is, Xi Yun's abnormality is not only a physical problem, but also another psychological problem, but for the latter answer, she really doesn't want to say it from her mouth.
