Chapter 403: Restructuring

In fact, Tu Qianjun had been thinking about changing the bullet caliber of the Tiger assault rifle to the small-caliber 5.8x42mm ammunition early in the morning. (--Net.) But at the beginning, because Americans didn’t like small-caliber guns, they didn’t have this.

Habit. So Tu Qianjun could only set the caliber at 7.62x39mm, an intermediate-power bullet.

But Tu Qianjun, who came from later generations, knew deeply that small-caliber rifle bullets were actually more suitable for combat!

The so-called small-caliber rifle bullets generally refer to ammunition with a caliber less than 6 mm and a projectile with a large aspect ratio. It has been proven in actual combat that small-caliber rifle bullets will become unstable and roll after hitting the human body at high speed, causing large-scale trauma to human tissue. They mainly shoot 200 to

A living target within 400 meters.

In fact, in later generations, armies of various countries have set their own bullets in the small caliber of 5mm. For example, the standard used by NATO member states is the 5.56x45mm m197/ss109 bullet, and the 5.45x39mm m74 used by the former Soviet Union and Russia

/7n6 bullet, while China uses the 5.8x42mm dbp87 bullet.

The reason why it was adopted by various countries was that it was smaller than the 7.62mm standard rifle bullets and intermediate-power bullets at the time, and its effective range was farther than the intermediate-power bullets, so it was gradually replaced as the standard rifle bullet.

Unfortunately, Tu Qianjun's ideas were too advanced for others to accept. At that time, Zhang Xueliang was in charge of the Fengtian Arsenal, and Tu Qianjun was unable to carry out large-scale modifications.

Since you now have the final say, these flaws naturally need to be corrected.

There is also the fact that the initial Tiger assault rifle is not complete. In fact, Tu Qianjun has a better plan in mind! It is the type of gun he is accustomed to use in later generations - the Type 87 automatic rifle!

Many people know about the Type 81 automatic rifle, but most people don’t know about the Type 87.

In the 1970s, PLA was developing a new small-caliber bullet.--Net. The new ammunition required a new rifle to match it.

Therefore, the development of new ammunition was greatly delayed, but it was necessary to ensure that a new weapon could serve in the army in the early 1980s. As a result, this new weapon was still a Type 81 rifle using 7.62x39mm intermediate-power rifle bullets, and

It was not widely equipped until the late 1980s to replace the outdated Type 56 automatic rifle.

However, because I was worried about whether the new bullet gun system was really reliable, I had to use the relatively mature system at that time to add new bullets.

In 1984, the first batch of dbp87 rifle bullets were finally ready for mass production. Soon after, some Type 81 rifles were modified into special versions to use this new small-caliber bullet, which was the Type 87 automatic rifle.

The main purpose of this weapon is to convert the barrel caliber from the original 7.62mm to 5.8mm, but this rifle was only produced for a short period of time. Tests showed that the newly designed bullet has a higher efficiency than the 7.62x39mm

of superiority.

In 1988, the firearm of this system that fired DBP87 rifle ammunition was named the Type 87 automatic rifle.

The Type 87 rifle was only produced for a very short period of time, and production was completely discontinued not long after. The main reason for the discontinuation was the beginning of the design and production of the more competitive Type 95 rifle with a bullpup structure.

The Type 87 automatic rifle is roughly the same as the Type 81 in structure. The difference is that it fires small-caliber rifle bullets instead of medium-power bullets. The Type 87 uses a lot of new materials. In fact, the Type 87 is an enhanced version.

The 81 type.

Like the Type 95 and Type 03, it uses the 5.8x42mm bullet (dbp87 bullet) developed in China. However, what is even less known is that although this rifle has not been installed, it has become the most popular weapon of the special forces.

like!

Later armies did not install the Type 95 but instead were equipped with the Type 87. (--Net.) Even after the enhanced version of the Type 87, the Type 03, came out, those domestic colleagues of Tu Qianjun were still willing to use the Type 87. This shows that

This gun is truly outstanding.

Why do Tu Qianjun and his comrades prefer this rifle so much?!

Because the Type 87 is equipped with 5.8mm bullets, the ballistic trajectory of the 5.8mm bullets is low, the direct shooting distance is increased, and the danger zone is increased. Therefore, the direct shooting distance of the Type 87 5.8mm automatic rifle against a target with a height of 50cm is longer than that of the Type 81 7.62mm automatic rifle.

The rifle has an additional 100m, bringing it to 400m.

In this way, the shooter does not need to temporarily change the sight when shooting, and can shoot at targets within the effective range, thereby increasing the mobility of firepower and reducing the impact of ranging errors on hit calculations.

In addition, the bullet speed of small-caliber bullets is high, the flight time of the warhead is shortened, the influence of cross wind is reduced, and the hit error on moving targets is also relatively reduced. Moreover, the operation of this rifle is basically similar to the Type 81, and the structure is also similar.

You need to be familiar with the gun and its components can be interchanged when necessary. This is one of the reasons why they prefer the Type 87.

In the R&D room of Fengtian Ordnance Factory, under bright lights, Tu Qianjun pointed at the gun design sketch on the table to the technicians from various countries who surrounded him. The engineers said in a deep voice: "This is the rifle that everyone needs to improve.

This rifle is the 'Tiger Assault Rifle' I equipped before! Now I am going to install this gun in the entire army, and its caliber has also been changed to 5.8x42 mm..."

As he said that, Tu Qianjun took out another more detailed exploded diagram and said solemnly to the engineers who had gone through various reviews and were finally able to construct the new Tiger assault rifle.

"This is the exploded view, barrel assembly, bolt, bolt frame, recoil spring, guide rod..." As Tu Qianjun explained bit by bit, the eyes of these engineers could not help but shine!

The AK gun family is originally a gun family that integrates simplicity, practicality and reliability. When its ammunition supply system is changed to a small caliber, its accuracy is greatly increased! This makes this gun even more powerful!

"This is the basic structure of this gun!" After Tu Qianjun finished explaining, he took a deep breath and smiled at the engineers: "I hope you will perfect this gun as soon as possible and build the first prototype gun.

.”

Everyone couldn't help but nodded after hearing this, and then Tu Qianjun put down the drawings and left the R&D office. The R&D office was set up in a hidden mountainous area outside Fengtian City. A series of R&D equipment and R&D equipment were transported into the hollowed-out cave.

Precision machine tools.

There is also a team of dozens of technicians working with this office to make guns, and stationed here is a reinforced battalion of the Guard Regiment of the National Defense Forces Headquarters! Only three miles away from this mountainous area, there is a regiment of the Fengtian Garrison

Stationed!

Therefore, the security here is not too tight! And those selected engineers and technicians were all transferred to this R&D office after Tu Qianjun investigated their families through the North American Zhi Gong Tang and confirmed that there were no problems.

Inside.

Because he is worried that his gun structure will be leaked, at least for the time being, Tu Qianjun does not want his gun design to be leaked. The complete version of the Tiger assault rifle, which is the later Type 87, as its former user, Tu Qianjun knows it.

What an impact it will have in this era of single-shot rifles!

Therefore, Tu Qianjun did not want this gun to be used in battles against his own troops. Even before World War II broke out, he would not give the design drawings of this gun to the Americans.

After getting out of the cave, Tu Qianjun went through a series of obstacles and left the R&D center. He returned to Fengtian City, and then he summoned the former director of Fengtian Arsenal who was now in charge of Fengtian Arsenal and came back from Yanghu City in Shaanxi——

Jia Xiaohou!

This Jia Xiaohou is not a simple person! This person can be called one of the founders of China’s modern weapons technology industry!

Jia Xiaohou, courtesy name Baoshu, was born in Huxian County, Shaanxi Province. He joined the Chinese Tongmenghui after the Revolution of 1911. He was sponsored by the Republic of China government to study in Japan, the United States, and Germany, and was proficient in weapons manufacturing, bomb manufacturing, blasting and other professional technologies. Later he served in Manchuria

, director of arsenals in Shaanxi, Hubei, Gansu, Guangdong, Guangxi and other places!

He studied in Japan, the United States and Germany, and was not only proficient in the languages ​​of the three countries but also familiar with metallurgy and weapons manufacturing. He improved the 1924 Maxim heavy machine gun and added a water bag. He also improved the Krug field gun, increasing its range from 6,000 meters to 9,000 meters.

m. The imitation Czech 7.9mm light machine gun he designed was designated as the standard machine gun by the Ordnance Department.

He invented and successfully tested two-wing, three-wing, and four-wing rocket artillery shells with a range of 4,000 meters, which greatly deterred Japan's bombing of Xi'an at that time.

After the success of the U.S. nuclear test, Jia Xiaohou, while taking a part-time physics and chemistry class at the Shaanxi anti-Japanese cadre training class (at Cuihua Mountain in the Qinling Mountains), made a bold prediction: No matter how bold the Japanese are, they are afraid of the atomic bomb. If our country had the atomic bomb, the Japanese would not dare to do this

rampant.

During this period, he purchased hundreds of books on atomic energy and nuclear energy through various channels, and informed Hu Zongnan, Dong Zhao, Zhu Shaozhou and other senior generals of the government of his ideas. Unfortunately, they all believed that the research and manufacture of atomic bombs would take a long time.

, the cost is high, the technology is strong, and it may be beyond our capabilities.

What is even more regrettable is that after liberation, this scientist who insisted on staying in the mainland and even collaborated with Wu Hao and others was brutally suppressed. He was shot in 1951. Later, when the country was preparing to develop an atomic bomb, it remembered this scientist and planned to transfer his

At that time, they discovered that he had been shot several years ago. At that time, everyone couldn't help but feel extremely regretful.

Now, this scientist who had participated in the Revolution of 1911 rushed to the Northeast angrily after September 18th and recommended himself to Yan Zhengqing and asked to be the director of the Fengtian Arsenal! Yan Zhengqing certainly wanted such a talent, even for Jia Xiaohou

To play a greater role, Yan Zhengqing also arranged for Jia Xiaohou to serve as a professor at the Institute of Technology of Dongda University!

By the way, I translated the original engineering works. Jia Xiaohou was originally angry with the government's attitude towards the Northeast because of the September 18th and Shanghai Incidents, but now he met people like Yan Zhengqing who had similar experiences to him but were more knowledgeable than him.

people.

And since he still had the opportunity to teach students, he naturally stayed happily.

"Commander, you have something to do with me?!" Jia Xiaohou has the temperament of most scientists of this era. That is, he speaks directly and handles urgent matters! He doesn't like others to waste his time.
Chapter completed!
