After seeing off the black bull, Zhao Gang went to the arsenal again. A few months ago, the 1893 type rifle could be mass-produced. Zhao Gang is still full of hope for the progress in the past few months. In winter, Lianshan Pass and Motianling were covered with snow. They were dressed up as two warriors in white helmets and white armor. They looked even more majestic. They were covered with silver all over the way, which made people feel comfortable. Zhao Gang and several personal guards rode horses slowly, talking and laughing along the way, and more than ten miles arrived unconsciously.

When the guard saw that it was Zhao Gang, he did not dare to neglect and hurriedly let him in. A manager was serving him by his side. Zhao Gang asked, "Where is Mr. Zhan?"

Before the in charge could speak, the in charge heard a loud noise outside, just like a thunder sounded like a flat ground, and even the ground trembled like an earthquake. The in charge was so scared that he fell to the ground. The guard next to him was stunned for a moment and immediately surrounded Zhao Gang. At this time, the arsenal was in chaos, and several gongs were ringing and shouting together.

Zhao Gang waved his hand and first taught his personal guard to disperse, and then said to the in charge: "Don't panic, are you experimenting with new weapons today?"

The person in charge was originally confused, but when he saw Zhao Gang so calm, he was not so panicked, so he stood up and replied:

"Sir, today is experimenting with the new 75mm rapid-fire cannon."

Zhao Gang nodded. The 75mm rapid-fire gun was something Zhao Gang had just thought of recently. The biggest advancement in current artillery technology lies in the invention of the reversal of the reversal of the reversal of the gun, which replaced the reversal of the gun. Before the mid-19th century, the gun body of the gun was generally connected to the gun mount through the trunnion, which is the so-called rigid gun mount. When the rigid gun mount was fired, the gun mount was under great force, and the gun barrel and the gun mount were seated as a whole. Therefore, the gun had to be designed to be very bulky, causing difficulty in maneuvering on the battlefield. In addition, because the entire gun had a large displacement during the launch, resetting and aiming were a waste of time, which greatly affected the launch speed.

In order to solve the above problems, the artillery designers tried to install a buffer between the barrel and the base to reduce the force on the artillery mount when the artillery was fired. After a long period of exploration, in the early 1890s, the water-pressure spring-type retreat and re-advance machine of the artillery was finally created. This was a major breakthrough in the history of artillery development, and it marked that the artillery had entered the era of retreat from the era of retreat. Until the end of World War I, most countries believed that the hydraulic spring-type was the only way to achieve the system retreat and re-advance.

However, in the original history, the water pressure gas type retraction and retraction machine was first created by the French Moa in 1897, and was first installed on a 75mm field gun. The retraction and retraction machine was divided into two parts: retraction and retraction. The retraction machine consists of a retraction pipe, a piston and a liquid. The retraction pipe is connected to the connecting arm at the rear end of the gun body. When the artillery is fired, the gun body drives the retraction pipe to retreat. The liquid at one end of the piston flows from the leakage port to the other end. At this time, the liquid develops a resistance to slowly stop the retraction and slowly stop the retraction machine from the rear end. The retraction machine uses gas to absorb part of the recoil force. When the retraction and retraction machine is completed, the compressed gas pushes the recoil body to its original position. In this way, through the retraction and retraction machine, the barrel and the gun stand are elastically connected, which is conducive to reducing the weight of the artillery and creating conditions for increasing the launch speed.

In World War I, the French 75mm guns bombarded the German army at a speed of 30 rounds per minute (maximum 45 rounds per minute), while the German army used the new 77cm rapid-fire gun to fire 8 rounds of 6.85 kilograms of shells per minute. With the assistance of the perfect "water pressure gas type retreat and regression aircraft", the French 1897 rapid-fire gun can still perform perfectly when the projectile is heavier and the rate of fire is higher. More importantly, although the firing rate is so fast and the recoil is so strong that the entire gun will hardly cause displacement under continuous shooting, so the gunner can easily adjust the shooting elements between each shot to trim the bullet point.

After the First World War, all the debate disappeared, and the water pressure gas type became the only choice for artillery.

As for Zhao Gang's view, it is not difficult to manufacture a water-pressure gas-type rapid-fire gun. It can even be said that it is much easier than a water-pressure spring-type. This is a rare good thing for China with a weak foundation.

However, the experiment just now obviously failed and may have triggered the death of surrounding ammunition.

Zhao Gang was a little upset. Since the Qing Dynasty, he has been in every way and unconsciously regarded himself as a superman, wanting to change the dynasty with one person's strength. This incident awakened him like a basin of cold water, making him realize that China's foundation is still very thin now.

Suddenly, the door was opened, and a man ran in with a gust of cold wind. When he came in, he found Zhao Gang in the house and was stunned for a moment. When Zhao Gang saw that it was Zhan Tianyou, the general manager, and until he needed manpower, he smiled and said, "General Zhan, in the arsenal, I will listen to you. Just tell me what you have if you have anything."

Zhan Tianyou was startled by Zhao Gang's words, but the matter was urgent and he couldn't afford to delay. He also said with a smile:

"Mr. Zhao, just sit here to stabilize the morale of the army. I will be here for a while."

After saying this, Zhan Tianyou gave a few instructions to the manager and went out like a gust of wind.

After a while, the noise outside the door gradually became less and less. After a moment, Zhan Tianyou came in and bowed to Zhao Gang:

"Mr. Zhao, I'm so sorry, the experiment just now failed."

Zhao Gang's heart skipped a beat. Although he knew that it was roughly a failure in the weapon test, he was still very unhappy when he heard the news. Zhao Gang asked:

"What is the loss of personnel? Are the reasons for the failure found?"

Zhan Tianyou was a little depressed and cheered up and said:

"When the experimental artillery was experimental, there were 7 artillery developers and 12 operators, all of which were... killed."

Zhao Gang was disgusted. Although there were many people in the arsenal, there were only more than 100 researchers and only more than 100 operators. The explosion suddenly lost one tenth of the damage, which was a huge loss.

Zhao Gang was determined to scold Zhan Tianyou, but seeing that Zhan Tianyou was sad and couldn't bear it, he asked:

"Have the cause been identified?"

Zhan Tianyou shook his head:

"Not yet. When I find out, I will write a memorandum to explain it and resign from the position of the general manager."

Zhao Gang was shocked and hurriedly comforted:

"Why should Brother Tianyou do this? He has achieved remarkable results since he started the arsenal. Why did he want to resign from his post after a little setback?"

Zhan Tianyou sighed:

"Mr. Zhao has been exhausted recently. There are only a hundred people who are literate in the arsenal, and thousands of other people are illiterate. All processes must be taught step by step. Even so, there are often omissions. A few days ago, an ammunition loader mistakenly filled the ammunition with shells. Fortunately, it was detected on the same day, so it would not cause a disaster. Today's incident is mostly caused by too much shells loading."

Zhao Gang nodded, feeling helpless. There were not many people in the Qing Dynasty who understood the Westernization Affairs Bureau at all. If you want to cultivate it first, it would take more than ten years for a talent to be cultivated, and it would be far away and not quench your near thirst.
