Chapter 51 represents a qualitative leap compared to the original.
Lin Chuan developed a low-characteristic munition.
The combustion of gunpowder produces high-temperature, high-pressure gas, which propels the projectile out, while simultaneously generating muzzle flash and smoke.
Traditional silencers can reduce noise, but they cannot solve the problem of fire and smoke.
Lin Chuan developed his own gunpowder formula, which was completely different from traditional gunpowder. It had a lower combustion temperature, produced fewer solid particles, and contained a special flame suppressant.
However, DeepBlue Technology does not have a chemical plant, so it cannot manufacture bullets on its own, and it also lacks the relevant permits and qualifications.
This wasn't a problem, and Lin Chuan promptly sought Wang Chengjun's help again.
After listening to Lin Chuan's request over the phone, Wang Chengjun was silent for a few seconds: "You want to change the ammunition formula? This is a very complex thing; it affects everything from ballistics and chamber pressure to barrel life. Everything needs to be re-verified."
Lin Chuan said, "I know, but I can make a small number of samples first to verify the feasibility."
Wang Chengjun was silent for a moment, then replied, "Okay, I'll help you."
After waiting for about a week, three hundred rounds of specially made ammunition were delivered to Deep Blue Technology.
The gunpowder formula was prepared overnight by a research institute according to Lin Chuan's plan, and the bullet was a standard 5.8mm steel-core bullet.
……
At the firing range, Lin Chuan loaded a shot, aimed at the target fifty meters away, and pulled the trigger.
"puff--!"
The sound was even quieter than before, there was no flame at all, and almost no smoke.
Holy crap!
Huang Chongwei was astonished when he saw this.
"Boss, this gunpowder formula is something else! You actually made it work, amazing!" Huang Chongwei was shocked, but also full of admiration for Lin Chuan.
Lin Chuan smiled and said, "That's all we can do for now. When we have the conditions and the technology is mature, we still need to develop an electromagnetic rifle. That's the best weapon configuration for individual stealth combat."
However, it is impossible for traditional gunpowder firearms to be completely smokeless.
But Lin Chuan felt that he had achieved enough at his current level.
After a while, he fired a dozen more shots in succession. The barrel was warm but not red-hot. Each shot had the same effect: no flash, no smoke, and the sound was around 75 decibels.
"Measure the initial velocity."
After Guo Tao set up the speed measuring device, he fired a few more bullets.
Data shows that the bullet's initial velocity is 920 m/s, but when used on the modified QBU-191, the initial velocity of the low-characteristic ammunition is actually higher.
Because the new gunpowder formula optimizes the combustion curve, energy is released more fully.
The last issue is the cartridge case, which is the least noticeable but equally important improvement.
After a traditional rifle is fired, the spent cartridge case is ejected from the ejection port and falls to the ground with a clatter.
This is not a problem on a conventional battlefield.
But for stealth soldiers deep behind enemy lines, a spent cartridge ejected from their gun is like a finger pointing at them.
It's like telling your opponent: I'm here!
Moreover, the temperature of the cartridge case is extremely high, and the heat source signal will be captured after it is ejected.
Lin Chuan's solution was simple: add a cartridge case collection slot outside the ejection port.
It sounds simple, and it's actually not that difficult to do.
Anyway, it's easier than the previous questions.
The collection slot must not affect the reliability of ejection, as jamming is the most fatal malfunction of a firearm. It also cannot be too large, otherwise it will affect the mobility of the soldier.
In addition, it should be easy to disassemble and can be emptied quickly.
Lin Chuan designed a clever structure.
The collection slot is fixed to the side of the ejection window via a magnetic interface, and has a flexible guide plate inside to guide the spent cartridge cases into the slot.
The tank is made of Kevlar composite material, which is lightweight, wear-resistant, and non-reflective.
It has a capacity of thirty rounds, which is exactly the capacity of one magazine.
After firing, the soldier can remove the collection slot just like changing a magazine.
……
As time passed, in early August, in less than three months, Lin Chuan had forcibly "manually modified" a precision marksman rifle based on the QBU-191.
The efficiency was so high not only because of Lin Chuan's own abilities, but also because of the strong support from the military, which saved a lot of time.
During this period, all 17 improvement and optimization plans for the first-generation stealth combat suit were also resolved.
Next, Lin Chuan decisively made a decision to produce three sets of improved stealth combat suits, along with three modified 191 precision marksman rifles adapted to the stealth skin.
……
By mid-to-late August, three sets of improved individual stealth combat suits and three modified stealth precision marksman rifles were neatly arranged on the control panel.
At this moment, Lin Chuan, Cheng Siyuan, Song Yi, and more than a dozen others were gathered around the control panel, examining the results of their tireless efforts day and night.
Guo Tao crossed his arms, looked around, and nodded to himself, saying, "Hmm, at first glance, it feels like a qualitative leap compared to the first generation."
Actually, there aren't many changes in appearance, but improvements can be seen in the details.
The joints have more precise folds, the inside of the mask has almost invisible heating wires, and the skin surface has an extremely thin protective coating.
The modified Type 191 rifle is entirely covered with a matte coating.
It is non-reflective and the same material as the combat uniform.
Furthermore, the modified 191 rifle also possesses triple stealth capabilities, with the energy required for its stealth powered by the main power system of the combat suit.
The gun also has its own small power source to ensure uninterrupted power during operation.
The power connector is located at the grip of the rifle, and the other end is in the palm of the combat uniform. When the soldier's hand grips the rifle grip, the main power system is activated.
Once connected, the rifle's built-in battery will no longer consume power, and it will even reverse charge when the battery is not fully charged.
When you release the grip, the main power system of the combat suit is automatically cut off, and the suit is powered by its own battery.
魔改后的191，它的造价成本直接干到了92万之巨，而一把常规版的191步枪不过是6000元到8000元左右。
It costs 115 to 153 times more than the regular version. The cost of one modified version (191) can make more than a hundred regular versions.
Ammunition must also be configured separately.
Fortunately, the demand is not large. This individual combat system is too expensive to be deployed on a large scale, and the consumption is not high.
The modified 191 rifle is longer, has an integrated suppressor, and features heat dissipation patterns on its surface.
To the right of the ejection port is a flat collection slot that fits snugly against the receiver and is integrated with the gun body. The magazine is a standard 30-round magazine.
Lin Chuan picked up one of the modified Type 191 precision rifles and weighed it in his hand.
The other two were also being weighed by Guo Tao and Huang Chongwei.
Weighing 3.8 kg unloaded, it's neither too light nor too heavy, with a very even distribution of weight. The center of gravity is right at the front edge of the magazine, making it easy to hold with one hand.
Lin Chuan handed the modified 191 to Song Yi, then looked at everyone and said, "Pack them all up in a bit. We'll hand them over to the military for inspection at the usual place tomorrow. You guys are coming with me."
He led his team back to the secret military base from before, bringing with him three improved and optimized stealth combat suits and three modified Type 191 precision rifles.
