Blood-quenched mountains and rivers

As soon as Yang Wei returned to Shanghai, he went into the warehouse with great concentration and used the mechanical processing equipment imported from the Americans and his own experience in foundry to manufacture parts. Every day, except for Tieniu who went in to deliver meals three times a day, Xing Jun and Fang Dacheng, Wang Xiao, Li Tiegang, Qian Chengshan and others saw Yang Wei as if he had changed, so they couldn't help being curious and asked Tieniu: "Brother has been bewildered recently, what the hell are you doing hiding in the small warehouse?"

But Tieniu could only helplessly shrug his shoulders and said: "I don't know, he just looks at a pile of iron bumps and doesn't even look at me."

Yang Wei stayed behind closed doors, and few people dared to disturb him, so he could only practice the security team all day long according to Yang Wei's instructions. If it wasn't for von Box, a rare visitor who rarely visits the door, I don't know how long he would have to stay in the warehouse.

When von Box came to the door, he was in a hurry, and when he saw Yang Wei, he said proudly: "Mr. Yang, the five 75mm 42-caliber Krupp artillery you ordered are already on their way across the ocean."

It turned out that Feng Box came here proudly, but Yang Wei was not the least bit excited. He wiped off the sweat from his forehead and said, "You came just in time. I just have something to discuss with you."

Feng Box frowned and said, "What's the matter with Mr. Yang?"

Yang Wei took off his oil-stained coat and threw it to Xing Jun who was beside him. He waved to Feng Box and said, "Good business, let's chat over here."

The security team who were practicing outside were curious when they saw Yang Wei, and what was even more curious was that Yang Wei was still with a foreigner, but if they knew what Yang Wei was going to do next, they might be so surprised that they couldn't get along Mouth, anyway, von Box was really surprised. He stared at Yang Wei dumbfounded and said, "Tractor?"

Yang Wei took a sip of his coffee and said disapprovingly, "That's right, and it's a Trailblazer tractor manufactured by Chada Engine Company in Chicago, USA."

Not to mention Feng Box, who only met Yang Wei once, even Xing Jun, Fang Dacheng, Wang Xiao, Li Tiegang, Qian Chengshan, Tieniu and others who followed Yang Wei all day were all shocked when they heard this. Just like Zhang Er's monk, he couldn't figure out what Yang Wei was planning. Why did he need Krupp artillery a few days ago, and a Trailblazer tractor two days later?The gap between fighting and farming is too far away.

After all, von Box was young and full of curiosity, so he couldn't help asking Yang Wei: "Mr. Yang, can you tell me what you need the Krupp artillery and tractor for?"

It will inevitably scare them to directly say that he intends to build a tank. Yang Wei smiled proudly and mysteriously: "In short, what I want to do is a magical and great thing, and you will know it when you see it. In short, 'Baga ' tractor No. ’, please leave it to you.”

Ordering a tractor is not a difficult task for von Box, especially after hearing Yang Wei's tantalizing answer, von Box, driven by curiosity, agreed wholeheartedly, but he wanted to see Yang Wei. What exactly is he doing? If anyone in this world can combine agricultural production and mechanical arms, he would be considered a genius.

But Von Box did not expect that Yang Wei was indeed such a rare genius in this era.

In fact, ordering the tractor was just a cover. What Yang Wei really wanted was not the Pioneer tractor, but the gasoline engine of the Pioneer tractor. The No. 8 H tank made by the Germans used a Maybach engine and could reach a speed of four hours per hour. Ten kilometers, and the performance of the star-shaped V55 gasoline engine used by the Pioneer tractor is much higher than that of the Maybach engine, and the speed can be increased to [-] kilometers per hour, which has an absolute advantage in speed.

While waiting for von Box to deliver the pioneer tractor and Krupp artillery, Yang Wei focused on researching the improvement of the transmission device in order to adapt to various terrains and the coordination between the various parts of the device.

Because Yang Wei increased the frontal armor thickness of the No. 380 tank to 380 mm, and added [-] mm steel plates to the inclined armor, the track was seriously worn out. Although the structure of the [-] mm wide metal pin track is simple, the pins and The direct dry friction of the pin holes, combined with the increased overall weight, results in rapid track wear and short life.Yang Wei had no choice but to increase the track width from [-]mm to [-]mm in order to maintain the performance of the track.

On the other hand, if Yang Wei is going to use the Krupp artillery, he must consider the modification of the muffler. It is necessary to increase the muzzle brake at the muzzle, which can reduce the impact of the gunpowder gas energy on the recoil of the artillery during the aftereffect period. Because the reaction force of the Krupp artillery is quite large, the installation of the brake can absorb about 40.00% of the energy of the recoil, and reduce the burden on the gun mount, and at the same time improve the mobility of the artillery.

At the same time, Yang Wei is also planning to install a fully protected machine gun turret, and the processing method can choose casting turret or welding turret.However, the casting turret is a large casting. It is necessary to make a wooden model first, use the wooden model and then cast sand to make the casting model, and finally pour molten steel into it to cool and form. During casting, process defects such as sand holes and shrinkage holes must not appear, otherwise it will be serious. It affects the quality of the turret, and it is difficult to meet the standard with the processing level of advanced domestic factories, and only hemispherical steel turrets can be cast, and composite armor cannot be cast.In the end, Yang Wei could only choose a welded turret with high technical requirements and high cost.

Now that Yang Wei has financial and material support, the conditions for making the No. [-] H tank are far superior to the conditions for making the Tiger tank back then, which is enough for him to fight hard, but the difficulty of transformation is far greater Higher than imitation, when improving each component, it is necessary to consider the coordination between the improved component and the original component.

As a handicraft nerd who pursues perfection, since he decided to transform, Yang Wei will not tolerate any flaws in any part. This is also affected by his usual style of doing things, so countless attempts are inevitable. Armors, tracks, Every part of the turret has to go through repeated experiments by Yang Wei.

The more you put in, the more rewards you get. When the refit was completed, Yang Wei was overjoyed beyond words. He immediately went to the factory in Suzhou for a test run, and Yang Wei personally selected a few people from the security team for training.

Just to avoid being too public, Yang Wei did not install the artillery on the modified No. [-] H tank, but temporarily installed a machine gun instead of the artillery for driving training.

Facts proved that Yang Wei's caution was unreasonable. Although he was far away in Jiangsu, Huang Jinrong's people followed him closely, closely watching Yang Wei's every move.After learning that Yang Wei built such a tractor with a machine gun on it, Huang Jinrong smiled contemptuously and said, "He also built a fucking armored vehicle? He's just a bum. A machine gun is enough for him to get rid of it, so let him get rid of it slowly, can you "chaos" the world with just that gun?"

Although Huang Jinrong didn't take it seriously, the news of Yang Wei's manufacturing of the No. [-] H-type tank spread like wildfire, and instead attracted several mysterious guests who traveled thousands of miles to visit.
