Bright Sword Military System

Chapter 296 Spin Stabilization
The development of the rocket launcher quickly entered the right track.

The rocket launcher itself is not difficult, it is just a guide rail and does not need to consider the chamber pressure...

This is somewhat different from the rocket launcher. When the rocket ejects from the chamber, the rocket launcher relies on the principle of a recoilless gun to eject it. During this process, the rocket launcher needs to withstand a certain chamber pressure, and the wall of the barrel must be made thicker.

The rocket launcher flies entirely on its own power, so there is no such thing as chamber pressure.

Mao Xiong even used "I" steel at the beginning... two rockets were hung on each "I" steel, and one was hung upside down on the top of the bottom.

Although the use of "I" beams saves costs, the disadvantages are also obvious. It is not conducive to the maneuverability of the rocket launcher. There are more than a dozen rockets weighing tens of kilograms hanging on them. As long as there is a slight bump, the rockets will fall from the guide rails and cause accidents. .

Therefore, the "I" beam was quickly replaced by a cylindrical launch tube.

Wang Xuexin is basically designed according to the appearance of the 63-type 107mm rocket launcher:

The 12 launch tubes are arranged in three layers, four in each layer.

It is fixed with a gun mount, equipped with high and low wheels and direction wheels that can be used to adjust the height and direction.

Add two more wheels for maneuvering below and you're done.

The whole structure is unimaginably simple, it looks like a farm tool.

The difficulty is still the shells.

The main problem is that the hand-made round-nosed projectiles of the Eighth Route Army cannot guarantee uniformity and center of gravity, so the rockets are likely to make irregular movements or even fly upside down after being fired.

This is a big problem. If one or two of them fly back, it will be enough to blow up the entire rocket artillery position into the sky.

On the other hand, if each shell moves irregularly, the spread range is too large to form effective firepower coverage on the target... The firepower coverage does not require high accuracy of the rocket shells, but it does not mean that there is a difference of [-] inside.

For this, Zhang Wanhe transferred Su Xin and Hardware, who were busy on the bullet production line, back for a meeting.

The meeting place is still Zhang Wanhe's office.

Now Zhang Wanhe finally used the kang, which Wang Xuexin asked Chen Fujun to build.

When Chen Fujun heard about this, he was surprised: "What? There is no kang on the roof of the factory manager?"

Wang Xuexin explained: "No, it was because fire was not allowed near the arsenal, but now the arsenal has moved, but there is no time to do it, so it was delayed!"

Chen Fujun replied with some embarrassment: "You blame me! This company commander only cares about safety issues all day long, and the factory manager doesn't even know it's useless to go to the kang!"

As soon as Chen Fujun patted his chest, he responded: "No problem, this matter is on me! I promise to let the factory manager sleep on the hot kang tonight!"

When it was over, Chen Fujun called the village mason, and while Zhang Wanhe was still busy in the factory, he built the kang and lit a fire.

Zhang Wanhe couldn't help being taken aback when he came back, and then smiled gratifiedly.

He first tried the top of the kang with his hands, and then sat on it carefully, feeling a sense of warmth spontaneously.

Zhang Wanhe was stunned for a while, unknowingly there were tears in his eyes, and it took a long time before he let out a long sigh.

Zhang Wanhe felt a little touched by this, and thought of his son who died on the battlefield.

If he is still here, he will do the same thing!
Just as he was thinking, there were several knocks on the door. Zhang Wanhe hurriedly wiped away his tears and sniffed before getting up to open the door.

It was several directors who came, and Wang Xuexin was among them.

As soon as Wujin entered the door, he said "Yo": "Director, it's time to get on the kang!"

Zhang Wanhe replied: "Isn't it? It's thanks to Xiao Dongbei, it's so fast, it was done in a blink of an eye, I thought I went to the wrong house when I came back!"

Everyone laughed.

Su Xin took a peek at Wang Xuexin, thinking, isn't this caring about people?why...

Thinking about it, he couldn't help sighing.

After chatting and joking for a while, Zhang Wanhe asked Su Xin and Wujin: "Have you all heard about the need for new equipment?"

"I heard!" Wu Jin nodded excitedly: "Good guy, a cannon that can fire more than a dozen rockets in one go, is this thing really possible?"

"Isn't this not done yet?" Zhang Wanhe replied, talking about the difficulties of the shells.

After hearing this, Wujin replied: "Director, this is not easy? Let's put fins on the rocket like a bazooka!"

Zhang Wanhe raised his eyebrows and said, "You can think of it but we can't? It's because this method doesn't work that I called you back to discuss it!"

"It doesn't work?" Hardware was a little strange: "Why doesn't it work?"

Su Xin continued: "The rockets of the rocket launcher are small in size, light in weight, and have a low muzzle velocity, so only a small tail fin is needed to stabilize the rocket. And the rockets of the rocket launcher..."

Hardware said "oh" and it was clear.

The rocket of the rocket launcher weighs 37 kilograms. If it is stabilized by the tail fin, it needs four tail fins larger than a palm to do it.

But such a large tail simply cannot fit into the launch tube.

This may be the reason why Mao Xiong used "I" steel as the guide rail at the beginning... Using "I" steel, there is no problem of inserting the tail into the launch tube.

"In addition..." Zhang Wanhe added: "Using the tail will inevitably have disadvantages such as high wind deflection rate and difficult production. Not only the cost is high but also the accuracy will be affected. Isn't that thankless? Is the tail fin feasible!"

Su Xin said: "It would be great if we could also engrave rifling in the launch tube to make the rocket spin!"

To solve the problem of the stable flight of the shell, except for the tail, it is to rotate.

But Su Xin is just talking, of course, you can't carve rifling in the launch tube to make it rotate.The more likely result of doing this is that the rocket gets stuck in the launch tube, and then "boom"...

However, the speaker had no intention of listening, and Wang Xuexin excitedly said, "Yes, spin! Why don't we let the rocket spin?"

Su Xin asked angrily: "Comrade Wang Xuexin, the problem is how to make it spin! It can neither be equipped with tail fins nor be rifled..."

"We don't have to use these two methods to make it spin!" Wang Xuexin replied: "We can use gunpowder!"

"Gunpowder?" Su Xin was puzzled.

"Yes, gunpowder!" Wang Xuexin explained: "We can change the tail nozzle, and add a few symmetrical small holes around it. They are at a certain angle to the horizontal line, so that they can rotate by themselves when advancing?"

Wu Jin couldn't help being stunned, and asked: "Is this possible?"

"I guess it can work!" Su Xin looked at Wang Xuexin in shock, nodded and said, "The key point is that the angles of the nozzles must be consistent, otherwise the accuracy will also be affected, which will increase the difficulty of processing!"

"Of course it's more difficult to play accurately!" Zhang Wanhe said, "Try and see if you can do it!"

"Yes!" Everyone responded.
