Spark

In fact, it has been more than three months since Chen Nian provided the core technology of the electromagnetic gun and was ready to be installed on the ship.

In the case that the theory has already been fully prepared, the first prototype was made in three months, and the speed is not too fast.

After receiving the call, Chen Nian immediately returned to his residence. After greeting Chen Guo, he drove to the Zhongbing 206 Research Institute.

Institute 206 is not far from Xigong University, only two hours away by car. After arriving at the place, Chen Nian found Wang Weibin, the person in charge of the electromagnetic gun project, according to the contacts Chen Guo gave. Some received him with trepidation.

"Chen Gong, I've been looking forward to your coming for a long time!"

"The technology you gave has at least advanced our electromagnetic gun technology for more than 10 years!"

"I've been looking for a chance to have a good chat with you, but I'm afraid I'll waste your time."

Chen Nian held his extended hand, smiled and replied:

"It's not impossible, our technology in electromagnetic guns is still very strong, at least one of the few fields that is stronger than Lao Mei's?"

Hearing his words, Wang Weibin scratched his head in embarrassment.

"Slightly stronger, Mr. Chen, let's go and see the gun now?"

"Let's go!"

The two walked out of the office and walked towards the experimental field.

On the way, Chen Nian suddenly thought of a question, so he asked:

"Do you have an engineer named Zhang Jiange here?"

"Zhang Jiange? We don't have one here. He belongs to Institute 713. He is the technical backbone there. He came to our institute to communicate with him before."

"Chen Gong, are you interested in him?"

Chen Nian shook his head, then nodded again.

He is indeed interested in this Zhang Jiange, but this interest is not a technical interest.

According to his memory, this Zhang Jiange should still be working in Zhengzhou at this point in time, responsible for the next sub-project of the electromagnetic gun project related to the length of the gun barrel.

His technical ability has been demonstrated to a certain extent, and he has also been reused by the 713 Institute.

However, such reuse does not pay off in the future.

The reason is simple, just a few years later, this person will become the biggest idiot in the history of China's electromagnetic gun development.

He provided a large number of confidential technical documents related to electromagnetic guns to the outside world, which greatly promoted the development of American electromagnetic guns, but it is ridiculous that his total profit from the beginning to the end of such a key technology was less than 200,000 US dollars.

If he can be more patient, wait a few years, and wait for the status of Huaxia's scientific research personnel to gradually improve, in the future, the reward he can get is likely to be more than ten times.

But unfortunately, he chose a wrong path.

After hesitating for a moment, Chen Nian said:

"This person. I have a certain understanding, and I think his technical ideas are good."

"However, it's not easy to make a conclusion yet. It is recommended to observe and observe."

Chen Nian didn't speak clearly, because in 2007, this person hadn't done anything illegal at all.

I can't call out the police in vain, saying that this person may become a spy in the future. Let's arrest him in advance or transfer him from key positions in advance, right?

This approach is neither rational nor smart.

Therefore, the best way should be to expose him to the sight of various departments, in other words, to keep a close eye on him.

If there are any abnormal signs, it is too late to deal with them immediately.

——

However, in fact, from another perspective, with Huaxia's current rapid development of electromagnetic gun technology, it is not so easy for him to leak secrets.

After all, before his key contribution to the project was published, he had already been blocked by Chen Nian. If he was not well-known in Laomei, he would naturally not be targeted as a "potential stock".

Wang Weibin nodded thoughtfully, and said:

"Then I'll mention it to 713 if I have the chance. If this person is really available, I might as well move up the transfer."

Upon hearing this, Chen Nian immediately understood Wang Weibin's implication.

Obviously, the other party can understand his hints.

Moreover, his handling method was just as he expected. He will not deal with Zhang Jiange for the time being, but he needs to strengthen his review and assessment.

Chatting with smart people is so comfortable.

Before Chen Nian had time to sigh, the two had already walked to the test site, and what caught their eyes was the electromagnetic gun that Chen Nian had been thinking about.

"This is our cannon!"

While touching the outer wall of the electromagnetic gun, Wang Weibin introduced to Chen Nian:

"The total length of the turret plus the gun barrel is 19 meters, the height is more than four meters, and the width is more than 6 meters."

"In general, the size is more than half smaller than the current experimental model of Laomei, and it has fully met the standard for boarding."

"The biggest problem we have to solve now is the problem of dedicated generator sets."

"Currently, there has been a breakthrough in Institute 704, and we are also in communication with Mr. Ma Weiming. It will be included in the unified layout of the integrated power system in the future."

"As long as the power problem is solved, there will be no obstacles for the electromagnetic gun to board the ship."

"It is even possible that we will directly use the electromagnetic gun as the main gun and the traditional naval gun as the secondary gun."

"This has to be studied further, there is no rush for now."

While listening to Wang Weibin's introduction, Chen Nian walked forward curiously.

He touched the barrel and asked subconsciously:

"Has it been changed to a rail gun?"

"Yes, changed."

Wang Weibin nodded slightly, and continued to explain:

"Originally, our direction was mainly coil guns, but since you have directly solved the problem of plasma ablation, then we don't have to worry about it. If we switch to rail guns, the effect will not be much worse."

In fact, the electromagnetic coil gun and the rail gun are two different design schemes of the same principle, and the two schemes have their own advantages and disadvantages.

Among them, the rail gun has the advantages of simple structure, high shell stability, and the initial velocity can be adjusted through the current, which has better flexibility.

Its disadvantage is that the skin effect is obvious, the ablation is serious, and the energy utilization efficiency is much worse than that of the coil gun.

And what about coil guns?

The energy utilization efficiency can reach close to 100%, there is no friction between the projectile body and the barrel, and there is less wear and tear.

But the problem is that the coil synchronization problem is difficult to solve, resulting in the stability of the projectile cannot be guaranteed, and the strength requirements for the armature coil are also very high, so it is very difficult to realize.

On the whole, with China's current industrial foundation and technological level, rail guns will be the most cost-effective choice in the next 20 to 30 years.

As for the coil gun, it can be explored and improved slowly after the technology is further matured.

After all, with the transmission integrated power system and super-high-power gas turbines, the mere 50% energy loss is actually not a big deal

"How is the effect?"

Chen Nian asked.

"Effects? You can try it now, Mr. Chen, let's see?"

Wang Weibin replied immediately.

Chen Nian couldn't help but want to laugh.

If you don't read it, why am I here?

So he said:

"Then try it."

Wang Weibin immediately picked up the walkie-talkie and led Chen Nian back out of the safe range.

Afterwards, the engineers who had been waiting for a long time went forward to complete the security check and preparations. After just a few minutes, the capacitor charging was completed and the huge cooling fan started to run.

For a moment, humming sound resounded throughout the testing ground, and with the lighting of various indicator lights, the temperament of the stainless steel test shed also changed.

From the original rural junction style, it has become a futuristic sci-fi style.

Reports from various staff members continued to come from the walkie-talkie.

"The preparation is complete, the charging is over, the target is locked, and the experiment can begin."

"The temperature of the gun barrel is normal, and the cooling is ready."

"Received, the fan has been turned on, starting to load."

"The loading is complete, the warm-up is complete, and it can be launched."

"Received, you can launch."

After the last report sounded, Wang Weibin turned his head to look at Chen Nian. Chen Nian nodded slightly. Immediately, Wang Weibin gave the launch command.

"Start trial shooting!"

"Start test shooting."

The operator finally repeated Wang Weibin's instructions, and then the launch button was pressed.

No symptoms.

First, there was a slight shock in the air, and then, the flame of plasma ablation rose from the guide rail, accompanied by the huge explosion sound of the shell breaking through the sound barrier, and the thick smoke produced by the ablation of the propulsion part of the projectile.

In just an instant, the firing was completed, and with the help of the automatic filling device, the second shell was immediately loaded onto the guide rail.

The fan of the cooling system quickly sucked away the thick smoke and the dust residue generated by the ablation, and discharged it to the rear end of the electromagnetic gun, and the temperature of the guide rail dropped rapidly.

In less than 10 seconds, the second shell escaped.

Then came the third and fourth shots.

After firing six rounds, the entire launch test was finally over.

Chen Nian looked at the electromagnetic gun after the launch in shock, then turned to look at Wang Weibin and asked:

"Have you completed the automatic loading system? What is the rate of fire?"

Wang Weibin nodded proudly and replied:

"Auto-reloading is nothing, just a gadget."

"Now we are still using the simplified version, which is fine. After it is actually on the ship, according to the performance of this gun, the maximum rate of fire can reach about 30 rounds."

30 rounds per minute, that is almost the same as the H/PJ-45A of 055.

The latter's maximum rate of fire is actually about 40 rounds.

"What about the range? How far can it reach?"

"Currently, the muzzle velocity is about Mach 7.5, and the firing range is about 400 to 500 kilometers."

"However, to achieve the ultimate range, the projectile design will need to be adjusted in the future."

"As for the power, we'll just have to look at it later."

"What about spreading?"

Chen Nian spoke again.

"The maximum range spread is about 200 meters, and the accuracy is already exaggerated-if the needle-shaped warhead is used later, the accuracy can be further improved."

"In addition, regarding the accuracy, we have cooperated with the 14th Institute to complete the design of the fire control radar of this gun, but there is no base installed, and the fire control radar will not be used for the time being."

"It's really strong."

Chen Nian said with a sigh.

In fact, although the accuracy of modern artillery has been greatly improved, it is still extremely difficult to achieve an accuracy of less than 100.

Even if the influence of external environmental factors is not considered, the 0.1% error in the detonation velocity of the gunpowder due to the air temperature and moderate temperature may cause the final drop point spread to be enlarged by more than 200 meters.

Not to mention the change in the initial disturbance factor caused by the change in air pressure after the temperature of the barrel increases.

And this newly born electromagnetic gun can actually achieve a spread of 200 meters at the maximum range-this cannot be simply called "powerful", it is simply incredible.

So now it seems that as long as the shells are powerful enough, it must be a certainty that the electromagnetic gun will replace the traditional artillery.

"Go and see the target."

Chen Nian said.

"Okay, let's go by car!"

Wang Weibin immediately arranged for the staff to power off and lock the electromagnetic gun, and did a safety check. Afterwards, the two went to the target one kilometer away.

It is said to be a target, but in fact, the cannon hit a string of "steel walls" just now.

More than 20 steel plates with a thickness of more than 10 cm were lined up in a row, and the six shells all penetrated the first 8 steel plates very smoothly. It was not until the ninth plate that the bullet holes began to appear irregular shapes.

This means that the tungsten alloy warhead has begun to deform and its kinetic energy has begun to decrease.

——

However, a decrease in kinetic energy does not mean a lack of kinetic energy.

All the warheads still firmly penetrated through 5 steel plates, and were finally blocked until the 14th steel plate.

"Amazing."

Chen Nian sighed involuntarily.

"Amazing, isn't it? Even a dedicated depleted uranium armor-piercing projectile can only reach a penetration depth of about 800mm at most. The tungsten alloy warhead used in this gun has a penetration depth of 900mm."

"If it's on land, one shell is enough to smash through three M1A2s."

"If it's at sea, for thin-skinned targets like warships, it's no problem to wear four or five ships."

". Too much penetration is not a good thing. This area needs to be optimized."

Chen Nian shook his head and continued:

"And I'm not saying the power is amazing, I mean the stability of this gun is amazing."

"Six shells were fired in different order, but there was almost no difference in destructive performance."

"This alone is much stronger than traditional artillery."

"After all, it uses electricity, and all parameters are controllable."

"Normally, the difference in muzzle velocity of each shell is within one hundred thousandth."

Wang Weibin stretched out his hand tentatively to touch the completely deformed warhead embedded in the steel plate, but he retracted it immediately before his hand got close.

"It's still hot, so don't touch it."

Chen Nian couldn't help but rolled his eyes, he didn't intend to touch it.

The two looked around the target twice, and Chen Nian finally had a basic understanding of the performance of the gun.

It appears that the design criteria were not only met, but exceeded.

When Chen Guo said on the phone earlier that "the ship is ready to board", she was not joking.

"When are you going to board the ship?"

Chen Nian asked.

"It depends on the plan of the 055 project team. However, I heard that it may be on the ship within two months."

"In addition, before the 055, we will use a 052 as a test ship. The transformation has been completed, and the sea trial will be carried out within this month."

"Within this month? So soon?!"

Wang Weibin nodded and replied:

"Yes, it's not too difficult. It's just using this ship as a platform, not pursuing combat performance."

"But it does fire, right?"

"of course."

Hearing this answer, Chen Nian suddenly had a bold idea in his heart.

At sea, it can launch.

Now that you've done all the fighting, why not

Some useful goals?
