Siheyuan starts from a better life

Chapter 268, Design Complete

"It's finally finished." After drawing the drawing of the last part, Jiang Yan stretched.

Seeing the pile of blueprints on his desk, Jiang Yan nodded in satisfaction. At first, Jiang Yan felt that he had blueprints for AK-47 and SKS semi-automatic rifles, and some blueprints for "August [-]" rifles, which he copied by himself. It will be quite simple to come out. When I really start to develop it, I will find that it is really not an easy task.

An excellent firearm design needs to consider the following aspects comprehensively:

Shooting accuracy: Shooting accuracy is an important indicator to measure the performance of firearms.Good firearm design reduces the spread circle and improves ballistic stability, making it easier for the shooter to hit their targets.

Reliability: The reliability of firearms is directly related to the safety of users.Excellent firearm design should ensure that the firearm can work normally in various harsh environments and reduce the failure rate.

Safety: Safety is the first principle of firearm design.When designing, it is necessary to consider various possible misoperations and install safety devices to avoid accidental injuries.

Comfort: Comfort is an important factor affecting user experience.A good firearm design needs to consider the comfort of the shooter during use, including grip, trigger, recoil, etc., to improve the stability and accuracy of shooting.

Ease of use: Ease of use is an important indicator to measure the quality of firearm design.Excellent firearm design should be easy for users to operate, maintain and clean, so as to reduce the difficulty of use and maintenance costs.

Adaptability: The design of firearms should take into account the needs of different users and have certain adaptability.Through adjustable design, modular structure, etc., the firearm can be adapted to different usage scenarios and user needs.

A mature firearm not only has the above but also includes various necessary tactical accessories, such as additional grips, sights and so on.

To design a gun, the most basic thing is to meet the conditions of the user.In fact, it is very simple, that is, "it is comfortable to hold, easy to fight, safe on the battlefield, and convenient to maintain."

Although I have a series of drawings and materials for reference, I have to solve some problems such as firearm structure problems, fire control system problems, and aiming devices, and I have only a half-knowledge of some things.

Fortunately, there are many engineers who specialize in the design of firearms in the [-] factory where he works. Jiang Yan often asks them about these things, and even the factory library is a place Jiang Yan often visits.

I didn't expect that it took me three whole months to do this. Fortunately, I finally copied this firearm.

The shape of the "August 14" type automatic rifle copied by Jiang Yan adopts the shape of the CS/LR47 automatic rifle called "the ultimate magic version of the Bayi type" by military fans in later generations. This shape is similar to the SL AK- The shape of the 47 is completely different, and it is closer to the shape of Western firearms. Later, people in other countries called the "August [-]st Type" the national version of AK-[-].

The magazine is modified, the guide rail is added, and the buttstock has also become a foldable buttstock. The 81 type designed by Jiang Yan is the same as the original 81 type. Not a lot, and Jiang Yan tried his best to correct his original shortcomings.

Considering that our country will adopt small-caliber automatic rifles with a caliber of 5.8mm in the future, the caliber of the Type 81 gun family is divided into two types: 7.62mm and 5.8mm.

The "August 955" assault rifle copied by Jiang Yan has a full gun length of 455 mm, a barrel length of 3.8 mm, and an empty gun weight of 8 kg. There is a place for adding a bayonet. The muzzle velocity is 720 meters per second, the theoretical rate of fire is 650 rounds per minute, and the effective range is 400 meters.

Along with Jiang Yan of the "Bayi Type" assault rifle, he also designed a matching squad machine gun, and the interchangeability of the two parts can reach 40%.
So the new "August [-]" copied by Jiang Yan is a grade better than the original one.

Now that it is August, although the temperature in Bingcheng is lower than that in Sijiucheng, the weather is still very hot at noon, making you feel breathless.

The old-fashioned electric fan above his head was creaking and spinning. Jiang Yan opened the drawer casually, took out a pack of cigarettes from it, took out one, lit it up and took a good puff.

"Boss, eat watermelon quickly, the watermelon with sand flesh is very sweet"

After taking two puffs of a cigarette, Xu Damao opened the door with some watermelons and walked in.

Seeing the watermelon brought by Xu Damao, Jiang Yan's eyes lit up, he snuffed out the cigarette he hadn't smoked in his hand, took a bite of the watermelon brought by Xu Damao, the watermelon was really sweet, and The watermelon he brought seems to have been chilled. In this summer, being able to have this iced watermelon is really priceless.

In this era, there is no so-called freedom to eat melons. There are limited varieties of watermelons in China, and there are not many planting areas. As a result, it is estimated that it will take many years for the country to realize the freedom to eat melons.

"Where did you get the watermelon?" Jiang Yan asked Xu Damao after taking another big mouthful.

At this time, Xu Damao finished eating a piece of watermelon before he said: "I bought a batch of watermelon in the field, and every worker has a share. Lao Guo took me through the relationship to put your share of watermelon in the refrigerator in the kitchen. It was chilled for a while, and I brought it to you when I felt that it was almost done."

"Is there any in Lao Guo's place?" Jiang Yan asked after taking a bite of watermelon.

"Yes, of course there is."

Hearing that he had his share, Jiang Yan ate the watermelon with confidence.

After eating the watermelon, Jiang Yan said to Xu Damao who was cleaning the watermelon skin: "After you finish cleaning in a while, go and call Master Sun Deshui into the office. I have something to do with him."

"Understood Boss, I'll call him over right away." After packing up, Xu Damao walked out of his office carrying the watermelon rind.

About ten minutes later, Xu Damao brought Sun Deshui to Jiang Yan's office, sweating profusely.

"Boss, I brought Master Sun here."

Hearing Xu Damao's words, Jiang Yan, who was sorting out the materials, looked up and greeted Sun Deshui when he came in.

"Master Sun is here, sit down quickly, Da Mao will pour a glass of water for Master Sun."

After the two sat down, Sun Zhishui said, "I don't know what Jiang Gong wants from me."

Hearing Sun Deshui's question, Jiang Yan got up and took out a drawing from a pile of drawings on the table and handed it to him, saying, "I invented something small, let's see if you can produce it, Master Sun."

Hearing Jiang Yan's words, Sun Deshui didn't open his mouth, but took the blueprint that Jiang Yan handed over and looked at it seriously. After looking at it, Sun Deshui frowned slightly. This thing is a bit too simple. A grader can make it out.

He closed the drawing and said to Jiang Yan, "No problem, it can be produced. This thing is not difficult."
