Zhu Youxiao just made an outline of the formation of the artillery unit, and then asked Sun Chuanting to preside over it. Sun Chuanting was also too busy to touch the ground at this time, who let him meet an emperor who knew more and more about calling people.

Zhu Youxiao recently discovered that as an emperor, many things can be done by others.

Of course, the military power still needs to be grasped, but the training of artillery is a tedious and tedious thing that needs to be explored, so of course it is impossible to waste time on it.

Sun Chuanting was ordered to form an artillery team, and soon found that the three-pound cannon was indeed good, but it was a little embarrassing. Because the royal military factory made a pound of cannon through the guò forging method, the weight was only 20 kilograms, and the front with a small two-legged gun carriage was only 23 kilograms.

This is from the Tiger Squat Cannon on the basis of the transformation, the Tiger Squat Cannon is the Ming Army's artillery is a relatively outstanding 'domestic goods', the weight ranges from more than 30 catties to several hundred catties, the combat mobility is very good, often a soldier can carry it on his back. During the battle, it can shoot scattered bullets at the enemy, and it has made great contributions in the anti-Japanese war.

When the military factory forged a pound of artillery this time. Compared with the 36-kilogram shells of the Tiger Squat Cannon weighing nearly 5 kilograms, the one-kilogram cannon of the military factory is 38 kilograms (23 kilograms) and fires 1-kilogram (600 grams) shells.

Just a change, there was a great difference in performance, because of the lack of fixtures, the firing projectile was too large, the charge was large, and the whole artillery projectile often jumped up when the guide was fired, which affected the shooting accuracy. The striking distance is about 160 meters, but the lethality at 160 meters away is slightly insufficient, and it is generally put into 80 meters away, and the lethality is the most terrifying, firing hundreds of lead bullets at one time.

The Tiger Squat Cannon has outstanding advantages, but its disadvantages are also quite prominent, its body barrel is short, it is difficult to provide a long range, and its accuracy is not high. Although the extremely simple gun carriage suppressed the upward jump, it also caused inconvenience in adjusting the firing angle - it could only be adjusted by digging a pit in the ground behind the rear of the gun. This makes the Tiger Squat Cannon not ideal for long-range use.

Because the weight of the projectile has been reduced, the charge has increased, and the range of the scattered projectile has reached 350 meters, and the accuracy has increased significantly, because the charge is not as large as that of the Tiger Squat Cannon, and the weight is heavier than that of the Tiger Squat Cannon, so it is more convenient to aim. However, it can only fire 25 lead at a time.

However, this kind of one-pound cannon is definitely a super weapon on the battlefield, because it is extremely lightweight, it can be directly put into the hands of infantry, and there is no need for any professional artillery team at all.

Since there is a one-pound cannon, do you still need a three-pound cannon?

Because the firing range of the three-catty cannon was not much more than that of the one-catty cannon, Sun Chuanting proposed to the emperor: "You can start to develop a new type of three-catty cannon, increase the length of the barrel to increase the firing range, and even if the weight is larger, it will not hurt." The three-pound cannon that has been developed is used to fire scattered bombs in front of the formation, and at the same time, a pound of artillery is distributed to each army, and it is lined up in front of the formation to fire at the enemy in wartime. ”

Zhu You calibrated Sun Chuanting's construction and asked the military factory to develop a three-catty gun with a longer barrel, and the weight was set at about 300 kilograms.

The weight of the three-pound gun increases, and the barrel can be lengthened, which in turn can obtain greater range and accuracy.

The weight of field guns is acceptable within 2,000 kilograms, large-caliber field guns are also being developed at this time, and the casting time of a cannon is still relatively long, mainly using clay molds. However, the mud mold is not too big a problem, as long as there is enough silver to smash down, the mud mold can be done more in advance, and the problem is not big.

Because of the direct pouring of steel, the cost is actually lower than that of iron cast guns. Because the quality of the steel is better, the material used is reduced. Moreover, the price of steel in the Royal Military Factory is also very low.

At the beginning of September, the Royal College of Science and Technology finally officially opened.

The first batch of students has been expanded to 500 people. Not far from the edge of the imperial city, Zhu Youxiao spent money to buy a large piece of land and built the Royal Institute of Science and Technology after demolishing it.

The reason why it was built outside the imperial city was mainly because it was close to it, and Zhu Youxiao used to give lectures to students and the like, and he didn't have to walk a few steps to get there.

The land of the Royal Institute of Science and Technology is still relatively large, with more than 200 acres of land. Even though the facilities were only partially repaired, there was no problem with the lessons.

The subjects of the Royal Institute of Science and Technology are divided into mathematics, physics and chemistry, and the majors are divided into agriculture, metallurgy, exploration, machinery, water conservancy, military industry, shipbuilding, navigation and other aspects.

However, for the time being, there is no major to be distributed, and I will study mathematics, physics and chemistry first.

The mathematics, physics and chemistry textbook Zhu Youxiao has been revised, although it is relatively simple, but it is definitely a weapon in this era! For example, Newton's laws are a theory that is suitable for this kind of primary industry, and at this time, quantum mechanics cannot be applied at all.

There is also the periodic table, which is a necessary guide for the development of primary industry.

It is equivalent to the students of the Royal Academy of Science and Technology, as long as they follow the periodic table, they can continue to carry out various chemical realizations, and then various inventions will come out!

Although Zhu Youxiao was a science graduate student before his crossing, his role in this era was actually to provide some basic mathematics, physics and chemistry textbooks.

Because the industry of later generations has developed to a very cumbersome point, and there are too many disciplines, so that they are very finely divided. Not like the inventors of the early twentieth century, who were both physicists and chemists. At that time, physics and chemistry were not separated at all.

The university knowledge that Zhu Youxiao learned before passing through has no application value in this era, but the mathematics, physics and chemistry textbooks in junior high school and high school are very useful.

These textbooks have been compiled for a while, Xu Guangqi is basically a little crazy, after getting the textbooks given to him by Zhu Youxiao, he almost can't get out when he plunges into it, and he either does this or that real all day long, or he is crazy about learning.

This time the Royal Academy of Science and Technology opened, Zhu Youxiao naturally had to be present in person, and Xu Guangqi also had to go with him, because Xu Guangqi would become a teacher at the Royal Academy of Science and Technology.

When they arrived at the Royal Academy of Science and Technology, all the students knelt on the ground and shouted long live to welcome the arrival of the Son of Heaven.

There weren't too many people, just five hundred. Zhu Youxiao, who has seen a big scene, five hundred people is indeed very few in his eyes! When I went to school in the future generations, which school didn't have thousands of people during recess?

Although there are only five hundred, if this group of people can be cultivated, they will be able to continue to cultivate many talents.

After Zhu Youxiao said a word, all the students stood up and observed Zhu Youxiao one after another. Zhu Youxiao is only fifteen years old, which is really young.

This is a young man.

Some of the students chose to come to the Royal College of Science and Technology, apparently at a risk. Because the emperor is so young, he may not be reliable in doing things!

Zhu Youxiao casually said a few words of encouragement to the students at the scene, which was nothing more than some to study hard and reimburse the country. Then the royal family's academic subsidies for them were announced, as well as a scholarship policy.

Because among this group of students, basically all of them are from poor families in ordinary families, and none of them are from particularly wealthy families, so Zhu Youxiao has formulated a very high subsidy, so as to hope that these students can not be affected by the impetuous atmosphere of society, concentrate on studying, and study practical learning.

The royal family will give them a subsidy of 3 yuan every month, and if these students want to get married and buy a house, the royal bank can give them interest-free loans, which basically eliminates their worries.

Among these students, there are many people in their twenties and sixties, and even those in their thirties. Survival is a problem they must consider, and the traditional etiquette has been severely impacted in the late Ming Dynasty, especially in the cities and coastal areas, whether it is the upper class of the elite or the bottom of the house slaves, they are very contemptuous of the etiquette, and their concept has become very gold-worshipping.

The formation of money worship has made people more and more impetuous. If Zhu Youxiao wants these students to study with peace of mind, these students must solve the problems of starting a family and starting a career and daily life.
