Sbilano finally fell into Tanaka's trap, and he willingly became a teacher, of course, he also brought some personal goods, and persuaded the teachers and students of the school to convert to Catholicism whenever he could.

In terms of faith, the laws of the Far Eastern Kingdom are very lenient, as long as it is not forced to induce others to become religious, it is legal, so for the first time, Sbirano felt that he had simply arrived in a paradise of freedom, and this kind of relaxed environment was not found anywhere else in the world.

However, because Spilano never left Ezo Island in his life, causing the Catholic Church he initiated to be disconnected from the European Holy See, after his death, it was naturally an independent church, and later generations did not recognize the European pope, calling his Catholicism a native denomination, which Sbirano did not expect.

……

"Ru Cheng, send someone to install this cannon mold, and try to make a cannon barrel first."

Yang Wenli took two guards and carried a cannon barrel extrusion mold and instructed Wang Rucheng.

Wang Rucheng habitually took a caliper to measure the size between the inner and outer molds, and said in surprise: "Your Majesty, why is this barrel mold so small?" The caliber is only 70 mm, which is not much different from the power of our 60 mortars, is it a bit of an overlap? ”

"I want a cannon too! But the road is too poor, we build a powerful cannon, first of all, our own artillery can't stand it, we have to take into account the actual use environment, this is a field artillery, not a fortified artillery, we have to consider convenience first, and then performance.

In addition, this is a howitzer, and the power of the shell, the accuracy of shooting, and the longest range are incomparable to mortars.

You can rest assured! Within a hundred years, this small field gun was enough. ”

"Oh! That's right! Wang Rucheng nodded thoughtfully in agreement.

The light field gun designed by Yang Wenli absorbed some of the excellent ideas of the Japanese Type 92 infantry gun during World War II, and the caliber of 70 mm was suitable for the ancient road environment at this time.

Of course, because of the different technical levels of the two, the field guns designed are also very different, except for the same caliber, there is no similarity.

Today's Far Eastern Kingdom, its industrial technology manufacturing level, especially the design level, has basically reached the level of the 21st century.

The design of the water criterion is because he is a pseudo-military fan, the construction principle of the cannon, the cannon concept of later generations, and the development process, which is far from the Japanese military designers during World War II, and the gap has an insurmountable gap.

First of all, the cannon he designed was not a bayonet cannon, but a guy who could hang the enemy from afar.

Therefore, the barrel will be appropriately lengthened, and it will no longer be as short and weak as the Type 92 infantry gun, like a larger anti-aircraft gun.

To do this, the material of the cannon tube steel is not simple, it is completely modern technology, first of all, electric furnace steelmaking, electroslag remelting, plus antimony, tungsten, manganese, vanadium and other rare metals with the help of the cannon tube steel, the cannon tube steel he remelted is the best quality alloy steel.

In addition, he designed the extrusion forming continuous forging and forming process, which is a technology only available in the 21st century, which has a significant increase in the performance of the gun barrel.

And he did not use the original mechanical buffer technology of the Japanese 92 infantry gun, but the use of air spring technology gun barrel short stroke technology, the principle is very simple, and the buffer effect is good, the barrel returns quickly, the only difficulty is that the sleeve material requirements are high, and the process precision requirements are high.

But with this air spring technology, the weight of the cannon will be greatly reduced, the structure is simple, no longer a square groove on the shape of a barrel, but the barrel directly on the shell chamber, too simple.

In addition, because the designed range has a maximum range of more than five kilometers, there is no cannon shield that can be used to get rid of the slag.

Of course, he also retained the method of high and low machines, left and right directional machines, and horizontal and large-angle firing by adjusting the cannon hoe, because the cannon is very light, and one person can easily swing it.

The gun carriage is exactly the style of the rear axle of a modern car, and the two wheels are also the steel wheel style of Hyundai, and they are as small as the wheels of the Geely QQ. The recoil of the cannon, mainly the gun hoe withstands, there is no problem with a smaller hub.

In this way, the final design of the cannon is a monster, too light, only 150 kilograms of weight, the height of the cannon is only less than 40 centimeters, like a heavy machine gun is better than like a cannon.

It also has a super long range, a large muzzle velocity, high accuracy, and a little bit of anti-aircraft gun feeling.

The most important thing is that the cannon is fast, and it has to fight with mortars, which is not at all the level of ordinary artillery.

The main difficulties of the cannon are the barrel and buffer mechanism, followed by the shells.

The cannonball is a big problem, but the problem of the cannonball is reduced, and the problem of the subsequent bullet is solved, because both are copper technology, copper primer, but the cannonball has an additional fuse process.

However, when Yang Wenli studied mortar shells, he had already solved the problem of collision fuze technology, so in essence, the two were a problem.

Why is it said that many countries in later generations could not make a single bullet? Think about it, how do you stamping a thin copper plate into such a pointed shape? Copper is so soft, no matter how it is stamped, it will break holes, resulting in stamping failure.

In order to solve this problem, military scientists have spent their brains and used a whole set of complex processes to solve this problem, and there are dozens of processes in stamping alone.

Because of this difficulty, many countries can only make round-headed bullets, but not pointed bullets.

In fact, many military technologies in later generations have been decrypted,The manufacturing process of bullets,It was put on TV without leakage,It is actually graded stamping,The stamping heads of the first few stages are round,Not sharp,Only the last tip is stamped with a sharp stamping head after it is burned red,It can almost be said that it is extruded and molded,It's just that this tip is very small,It does not affect the moldability of the bullet。

It seems very simple to say, but in fact it is very complicated, you must know that the bullet is manufactured, but it is fully automatic, and there is a complex set of equipment for the grading stamping just mentioned.

Yang Wenli wants to improve the method, not to copy the experience of others, since the final stamping of the bullet tip, almost extrusion die casting, then why not directly solve the problem on an extrusion die casting process?

Of course, it is not that simple, the disadvantage of the hot casting process is that the material is too brittle, so there must be an annealing procedure. This annealing process alone is not simple, and it is still the exclusive technique of many top large companies in later generations.

But Yang Wenli is open, he can use his divine sense to observe the crystallization changes of materials during annealing, extremely subtle changes at the atomic level, which no high-tech equipment can do even in the 21st century.

How long should it be annealed? What is the best temperature? He only tried once to fully know, and others have to go through an unknown number of tests to get this experience, so Yang Wenli of course chose a hot casting molding process.
