Having said so much, in fact, it is just a sentence, and now it is impossible to make an ordinary bullet of Type 56. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Although there are some regrets, Yang Chong can forget it if he thinks about it. After all, Daming started from scratch, and it is not easy to develop into this.

Moreover, through the current machine tools, some inferior bullets can be manufactured, and they can also be used.

Later, he visited the cannon produced by the Ming Dynasty - the light cannon.

From the initial Light Cannon to the present, it is the third generation.

A cannon usually consists of two parts: the gun body and the gun carriage. The gun body includes the barrel, the gun tail, the gun latch, etc. The gun carriage consists of an anti-recoil device, a steering machine, a high and low machine, an aiming device, a large frame and a sports machine.

As early as 1332, the Yuan Dynasty of China was armed with the earliest metal barreled artillery: the bronze firecracker. With a caliber of 105 mm, a weight of 6.94 kg and a length of 35.5 cm, it belongs to the smoothbore front-loading gun.

In the 17th century, the Italian physicist Galileo's ballistic parabola theory, and the English physicist Newton's research on air resistance, promoted the development of artillery.

In this era, the cannon was still a smoothbore front-loading gun. Most of the shells used were explosive bombs, shotguns, and shrapnels.

Although the Ming Dynasty had a forward-looking understanding of the development of artillery. But there is no corresponding talent.

Today, cannons are made mainly by craftsmen dug from Europe. The Ming Dynasty basically plays the role of a guide. For the craftsmen, plan the direction of development.

In terms of range, the third-generation Bright Run did not break through much. But the variety of shells is much richer.

Obviously, we have to keep up the good work!

According to the process, Yang Chong left the arsenal after making an impassioned speech.

He was accompanied by Mu Chun. As Minister of Industry, he was to accompany Yang Chong to his next stop, the steam engine factory.

Because the steam engine is the only source of power for the Ming Dynasty, it has a far-reaching impact on the development of all walks of life in the Ming Dynasty.

Although the UK has been implementing a technological blockade, Daming has also poached a lot of technical talents. Especially among the insiders of the Ming Dynasty, there are also several who have learned mechanical energy and dynamics.

In this area, it is still the same.

Most people think that it was Watt who first invented the steam engine.

But in 1689 Thomas . Savelly, Thomas in 1712. Newcomen, both than James in 1769. Watt early.

It's just that Watt made a series of improvements to the steam engine on the basis of Newcomen, and added many new components. For example, separating condensers, insulation layers outside cylinders, oil-lubricated and sliding pistons, planetary gears, parallel motion linkage mechanisms, centrifugal governors, throttle valves, pressure gauges, etc.

On the basis of the original, the efficiency of the steam engine was more than tripled.

Therefore, he was not the inventor of the steam engine, but the improver.

The earliest true-air steam engines, which shrank inward when the substance was damaged, were relatively safe, but inefficient. Later, high-temperature and high-pressure steam engines were used, and although the efficiency was improved, the danger was greatly increased.

It's just that compared to efficiency, security has been artificially neglected.

Let's talk about the power and efficiency of the steam engine.

This is reflected in the steam parameters. The steam pressure of the initial steam engine was only 0.11~~0.13 MPa, and it only reached 0.35~0.7 MPa in the early 19th century. In the 20s of the 20th century, it reached 6~10 megapascals.

The steam temperature has also increased from less than or equal to 250 degrees Celsius to 450~480 degrees Celsius.

As for the speed, it ranged from 40~50 rpm at the end of the 18th century to 100~300 rpm at the beginning of the 20th century. There are also individual steam engines that reach 2500 rpm.

Of course, this is all from the original plane.

After the improvement of the Ming Dynasty, the speed and power are higher than this era. Although it did not reach the level of the early twentieth century, it still caught up with the footsteps of the mid-nineteenth century.

Its structure mainly includes cylinder, base, piston, crank connecting rod mechanism, slide valve distribution mechanism, speed regulating mechanism and flywheel.

The cylinder and the base belong to the stationary part.

When working, the burning boiling water releases a large amount of steam, which passes through the pipeline and is transported to the cylinder.

The steam then pushes the piston inside the cylinder to do work, and the cooled steam passes through the pipes and is introduced into the condenser to re-condense into water.

This process repeats itself and becomes known as the 'piston movement'.

It has a wide range of applications in mining, textile, steel smelting, transportation, etc.

In charge of the steam engine factory was a Nanyang Chinese immigrant named Liu Tingfang.

He was born into a military family in Siam, after a coup d'état in Siam established the Bangkok dynasty. He fled with his family to the Malay Peninsula in the South Seas.

When he grew up, it happened that a British merchant ship recruited a crew. In order to ease the burden on his family, he volunteered to become a British sailor.

Later, when he arrived in England, he accidentally entered a steam engine factory, where he was apprenticed.

Probably, in theory, he is no better than those who have gone out of college. But in practice, he has accumulated extremely rich experience.

In addition, after the last cleaning of Daming, many key positions have been vacant. Some people with excellent performance also took advantage of this opportunity to be promoted.

"Good President, good Minister Mu." Liu Tingfang stood at the door with a group of workers from the steam engine factory and welcomed in unison.

If it is not stipulated by the Ming Dynasty, the leader will inspect and cannot put on a show. Liu Tingfang can really make it here~ to show the red flag, which is extremely grand.

"Good, good! Director Liu and the workers, I'm afraid they've been waiting for a long time, right? Yang Chong cordially held Liu Tingfang's hand and took the lead into the factory.

This made Liu Tingfang so excited that she thought she was dreaming. After all, Yang Chongke is the president of the Ming Republic, and he usually can't even see each other, let alone shake hands.

Now he has the feeling of flying up to the clouds, fluttering!

"No-no-no! When we heard that you were coming, President, we had only been waiting for an hour and a half. Liu Tingfang replied a little crampedly.

In this regard, Yang Chong is also accustomed to it.

People in this era have a deep-rooted concept of hierarchy. It is believed that the official is the official, and the people are the people. At all times, the officials are superior to the people.

Although the Ming Dynasty also has a hierarchy, in actual life, there is no such explicit rule. In many cases, the concept of hierarchy is deliberately downplayed and everyone is equal.

Strict requirements are also imposed on all officials, and there is no need to put on an official show. I don't want to be able to truly be close to the people and love the people, but that posture must be seen by people.

Like the annual performance appraisal, Daming's Discipline Inspection Department will conduct public opinion evaluations on officials. In the area under the jurisdiction of the official, a random selection of people asked them to rate the local officials.

Although it cannot have a substantial impact on the career of officials, there are still some slight obstacles. For example, the year-end bonus is less than others.

Liu Tingfang felt the goodness of Daming, so he worked hard and served Daming. Eventually, he became one of the few Nanyang immigrants in senior management.

Because the major factories are still in charge of modern people who are also traversers.

Liu Tingfang can squeeze into this circle, which is enough to prove his excellence.

(I'm busy looking for a job, so please forgive me.)
