"Let's go! Let's go! Go and see the bullet point! ”

"Take shovels, pickaxes, and pickaxes, and come here young and strong!"

After a short period of joy, Wang Ye waved his hand and said so, Commissioner Huo next to him nodded, and then more than twenty young men, holding various tools, followed.

A moment later, the group came to the foot of the mountain a kilometer away.

Seeing that the sandbag wall that was the target had been torn out of a huge hole at this moment, Wang Ye bent down and looked carefully at the side, and finally picked up a fragment about the size of a melon seed skin.

"It seems that the speed is done, but we have problems with the material and the process of the metal rod."

"It's just such a layer of sandbags, and it can fall out of such debris."

"It means that the overall density and hardness are not enough!"

As Wang Ye spoke, the metal fragment in his hand was handed to Commissioner Huo next to him, and Commissioner Huo looked at the fragment in his hand that was obviously shattered by the impact, and let out a breath of white air and nodded.

Then Wang Ye crossed the sandbag wall, and ten meters behind the sandbag wall was the root of the mountain, and he could see that there was an obvious entrance to the mountain, and the surrounding soil was thrown away, forming a "crater" with a diameter of more than half a meter, and there was a black hole in the middle, and it was obvious that the metal rod had shot into it.

"Young men, the fool moves the mountain and digs!"

"Let's pull the warhead out of the mountain, I guess it shouldn't be too deep!"

Hearing Wang Ye say this, there was a burst of laughter at the scene, and then the young people waved the tools in their hands and began to dig at the foot of the mountain, looking for the metal rod warhead.

As for the "old people" such as Wang Ye and Commissioner Huo, they naturally didn't need to do it themselves, watching the young people work, and chatting about the project at the same time.

"At least one thing has been proven now."

"There is no problem with the idea of large aspect ratio proposed by the factory director, and with large caliber and high bore pressure, it can effectively improve the muzzle velocity of our bullet core!"

"And improve our armor-piercing ability!"

Commissioner Huo took out a cigarette, took out one and handed it to Wang Ye, Wang Ye waved his hand and said that his throat hurt, and then Commissioner Huo lit it and smoked it by himself, spit out a puff of white smoke and said.

At present and in the next few decades, the most effective weapon in the fight between tanks is the tail stabilized shelling armor-piercing projectile, and this bullet is essentially a kinetic weapon, its core is like a steel needle, there is no explosives inside, all rely on high kinetic energy to penetrate the armor of the enemy tank, and to improve the kinetic energy, there are only two methods, the first is to increase the muzzle velocity, and the second is to improve the quality of the core.

If you want to increase the initial velocity of the muzzle, there are many ways, but it is intuitively summarized into four points, the first point is to increase the chamber pressure, including the change of propellant, the increase of the charge, etc., the second point is to remove the rifling, after all, the spin and friction will definitely reduce the speed, the third point is to increase the length of the barrel, after all, the barrel is long, the work of gunpowder gas will also increase, and then you can naturally get more acceleration.

As for the fourth method, it is more complicated, and that is to reduce the mass of the launch department.

Theoretically, the greater the thrust and the smaller the object being pushed, the higher the velocity of the object can be obtained, and in the field of tail stabilized disarming armor-piercing projectiles, this problem is a complex trade-off.

Because the second issue involving the improvement of kinetic energy is the mass of the bullet core.

According to the kinetic energy formula ke=0.5*mv2, the faster the speed and the greater the mass, the greater the kinetic energy, and the greater the power of the armor-piercing projectile that reflects the stable deshelling of the tail.

In order to improve the quality of the bullet core, the mainstream method is to use high-density metal to increase the mass of the bullet core per unit volume, and then provide kinetic energy, such as tungsten alloy and depleted uranium metal.

In this way, there is a contradiction between this point and the fourth point of increasing the muzzle velocity, on the one hand, in order to increase the velocity of the bullet core, it is necessary to reduce the mass, and on the other hand, in order to increase the kinetic energy of the bullet core, it is necessary to increase the mass, and the contradiction seems irreconcilable.

In order to solve this problem, the world's various industrial powers, major artillery companies have tried all means, using a variety of calculations, and even computer simulations, even after a few decades, this problem has not been "perfectly" solved, but with the deepening of calculations, the development of other technologies, has obtained a lot of relatively advanced solutions.

However, in the process, there is a development direction that has been determined and considered relatively "correct".

That is to increase the length-to-diameter ratio of the core.

The so-called length-diameter ratio is the ratio of the length of the bullet core to the diameter of the bullet core, in the era when the original tail stabilized shelling armor-piercing bullet was invented, the diameter of the bullet core generally exceeded 40mm, and the length-diameter ratio could not even reach 10, such as the current T-72 tank, the use of the Soviet Union 78 years of production of 3BM12 tail stabilized shelling armor-piercing projectile, the core of the bullet has 51.8 mm, the length to diameter ratio can reach 10!

The reason for increasing the aspect ratio involves very complex problems and finite element analysis, but it can be simply summarized as: the core attack armor is like digging a pit, and in the process of digging a pit, the core will be constantly worn, theoretically the longer the core, the deeper the pit is dug, which represents the deeper the penetration, but in practice there are many other influencing factors.

In fact, according to Wang Ye's memory.

In normal history, today's world-class arms companies and research institutions have taken the length-to-diameter ratio as one of the development directions for research, but it is only one of the directions, not a definite inevitable way, such as a larger caliber, which is also one of the directions of their research, in order to counter the Soviet Union's steel torrent, in fact, whether it is Britain, Germany, France, or the United States, they are all studying 140 mm super-large caliber tank guns separately or jointly.

After all, panic! The current Soviet Union is too radical to resist it!

The development direction of the length-diameter ratio of the tail stabilized shell-out armor-piercing projectile was really determined about 85 years, and Rheinmetall was the first to discover this crucial point, and since then the size of their bullet core has begun to decline all the way until it is more than 20 mm in the nineties, exceeding the length-diameter ratio of 25.

However, in Huaxia, in the past, the tank gun started with the technology of Big Brother, and after the big brother got stiff, it used the technology of the captured Big Brother, and then the Western 105 rifled gun technology that was introduced, and now it has not been thoroughly understood, so it is not involved in the research field of aspect ratio at all, coupled with the lack of computers, finite element analysis is difficult to do, and this field is even more blank.

"But to be honest, when the factory director proposed that we should make a 22 mm diameter bullet core, with a length-to-diameter ratio of 25, my whole brain is buzzing, isn't this just a steel needle?"

"Does this thing work? Can you pierce through the thick armor of a tank? ”

"Now it seems that if you don't accept it, you can't do it! Or the factory director, your new ideas are amazing, our group of old guys, our imagination is a little unable to keep up! ”

Subsequently, hearing the voice of Commissioner Huo, a technician said with emotion, while another staff member nodded and said:

"Yes, but the direction is correct, but the problem is also significant."

"The main reason is that our materials are not up to par, and this core is too thin and long, resulting in insufficient overall rigidity and strength."

As soon as he finished speaking, he heard the young man over there shouting:

"Found it! Director! Commissioner! Got it! ”

"Come and have a look!"

With this voice, Wang Ye, Commissioner Huo and others rushed over, only to see that a large piece of soil had been dug up by young people at the foot of the mountain, and the bullet core appeared in everyone's field of vision.

Sure enough, the first half of the entire core was completely shattered, and the second half was slightly bent, which in turn caused a large angular deflection of the incident trajectory of the soil, rather than a theoretical straight line.

"Whew! In any case, today's experiments at least proved that there are no problems with the body and barrel of our guns. ”

"Withstood such a high chamber pressure, there was no explosion, the air tightness was also very good, there was no air leakage to cause pressure relief, and our propellant also performed very well, and the strength is very great!"

"The rest, whether it's the deformation of the barrel, the wear of the coating, or even the overall rigidity and durability of the barrel, requires a lot of subsequent testing."

"And this bullet core, we have to think of a way."

At this moment, Commissioner Huo didn't seem discouraged at all, picked up a bullet core with threads, and said with a smile.

Then Wang Ye took the half of the metal rod from his hand, nodded and said:

"Indeed, the next research on the material problem of metal armor-piercing rods needs to be put on the agenda more urgently, but I am afraid it will be difficult to overcome in a short period of time, and we cannot hang ourselves from a tree."

"According to the old plan, we carried out the test of the increase amount of the projectile body, as well as the amplification test of the diameter of the bullet core, and we used hundreds of experiments to find a suitable ratio."

"Let the No. 2 Metal Factory start producing homogeneous armored targets!"

According to the original plan, the length of this shell is not the current one meter three two, but an astonishing one meter four five, that is, the theoretical calculation of the limit bore charge that this gun barrel can withstand, but in order to ensure safety, so the early time will not be so exciting.

In addition, Wang Ye also knows that the initial velocity of this experimental cannon is related to its small-diameter core, core and three-lobed butt, as well as the large-caliber charge.

In a sense, the current gun is a real complete body, but because of the technology, it is only in a verification state, and in order to achieve the actual combat level, subject to today's materials and manufacturing processes, the diameter of the core will definitely continue to increase, such as increasing to 28 mm or 32 mm, or even 35 mm, it is possible.

As the weight of the core increases, the weight of the core and stock will increase while maintaining the 25 aspect ratio, and the muzzle velocity will become lower and lower, to 1800, 1700, or even 1600 or 1500.

Finally, through the tail speed test of the two-kilometer range and the actual target shooting effect, the best plan can be selected from many permutations and combinations, and the finalized production can begin.

All in all, no matter what, this is also the best plan that Wang Ye can think of at present.

In essence, the 140-caliber tank guns engaged in by Western countries are also such an idea, using a larger caliber, loading more medicine, and hitting the armor-piercing metal rods that used to be, the armor-piercing effect will naturally increase.

And for Wang Ye.

Only then will it be possible to master a weapon that poses a mortal threat to enemy tanks!

In fact, today's domestic main battle tanks, such as the 59 and 69, are equipped with 100 mm and 105 mm smoothbore and rifled tank guns, and in the face of opponents such as the T-72 equipped with 125 mm cannons, especially the version with composite armor produced by the Soviet Union, the firepower is actually insufficient and does not have any advantages.

It was because the troops knew this that they introduced a 105 mm rifled gun from the West, but after testing, it was found that the power of this gun was still not enough, and finally after magic modification, the length of the barrel was increased, so that it could have a theoretical threat to the T-72, and at that time, it was actually in the mid-to-late eighties.

In a sense, it's good that there is no fight, but if it does, it will be a big trouble!

But since learning that the conflict between India and Pakistan broke out, Wang Ye estimated that the actual battle would come soon, after all, Pakistan is equipped with a large number of 59 and 69 tanks, while India is equipped with a lot of T-72 tanks.

Because during the second Indo-Pakistani conflict, Pakistan almost lost because of the lack of tanks because of the sudden abandonment of weapons support by the United States, and in the face of India's armored army, it had no way to come to ask for help, so the troops directly transferred the 59 tanks in active service, more than 1,500 units before and after, and relied on the superiority in numbers and artillery to turn the tide of the war.

"However, there is still a problem."

After Wang Ye's voice fell, Commissioner Huo hesitated for a moment before saying:

"To be honest, our cannon is a bit big, although the size of our new tractor is not small, but it is still a certain trouble to stuff it in, plus the loader, it is even more difficult to do."

"So I think we should still use this gun as a basis and develop a slightly smaller caliber."

"For example, the 120 caliber of the West, or the 125 caliber of the USSR."

In response to this statement, some people nodded and some sighed, and one of the elderly researchers said "sigh":

"That's the truth, but if the caliber is lowered, the power will be reduced."

"At the current level of this gun, if it is reduced to a caliber of 120 millimeters, the cartridge will be reduced from 1.3 meters to less than 1 meter, and on the basis of maintaining the size of the core, I estimate that the initial velocity of the muzzle can reach more than 1,040 is considered good."

"With such kinetic energy, the armor-piercing depth is not enough!"

Wang Ye also smiled helplessly, then patted Commissioner Huo's arm and said:

"The idea is right, you can do it in this direction."

"After all, if the 120 cannon is powerful enough, the turret is small, the trolley is heavy and light, and the armor can be loaded with more, it is naturally good, but our current technology is not enough, and we can't have both and more."

"So the 120 and 125 projects must be our focus in the future, but now my requirements are still the same as before."

"Perfect this gun, and then find a platform to install it, even use the most old 59 in our factory, even if it is made into a tank destroyer, as long as it can run and fight."

"I don't want to turn back the wheel of history, but it's okay!"

Hearing Wang Ye say this, Commissioner Huo smiled, pointed to the southwest and said:

"Director, are you worried over there?"

"Think something is going to go wrong?"

Regarding the conflict between India and Pakistan, the top management in the factory is not confidential, after all, this is also a point that Wang Ye has always emphasized, to find out the market context and provide the products that the market needs, so if the scientific researchers don't even know about the war and don't know what they are fighting, then how to carry out the right research and development?

"Yes!"

Wang Ye did not deny this.

Commissioner Huo smiled, threw the cigarette butt, and then nodded and said:

"Okay, then we'll make a finished product first."

"Solve the problem from scratch first, and then solve the problem from existence to strength!"

Hearing this, Wang Ye nodded in approval, and finally gave instructions to Commissioner Huo:

"By the way, the person in charge of purchasing the minibus will be here tomorrow."

"I'm going to show him our cannon then, and I'll find a tattered 59 for the target!"

"A kilometer away, adjust the angle, I think it will definitely not be a problem to make a hole in the eye no matter what, anyway, as long as you don't lose sight."

Regarding Wang Ye's order, Commissioner Huo nodded and smiled:

"Then there must be no problem, how much is the side armor of 59?"

"Although our armor-piercing pole is not very good, it is more than a meter drilled in the soil!"

Subsequently, everyone left the test range, and this treasure cannon naturally had to be brought back for a detailed inspection, including the deformation of the body tube, the wear of the plating, the destruction of air tightness, the accuracy of the bolt closing, etc., and the cartridge was also brought back to analyze the residual propellant to determine its combustion, as well as the deformation of the cartridge barrel and so on.

Back in his office, leaning back in his chair, Wang Ye breathed a sigh of relief.

After thinking for a while, he began to write down suggestions and questions related to the National Military Industry Chain Conference, and soon the time came to night.

The next morning, early in the morning.

The entire consortium is ready to entertain the "distinguished guests", after all, this is really expensive, and it is also the first time that such a distinguished guest in the consortium has taken the initiative to come to the door and ask for weapons!

Eleven a.m.

With the roar of the engine and the smoke and dust, the team drove into the gate of the complex, there are many onlookers today, but there is no gong and drum team, just a variety of red banners, on which are written a variety of bilingual friendship slogans, it looks warm but not exaggerated, and after the car stopped, the scene sounded thunderous applause!

Regarding this scene, Zhou Jinlie and Wei Qingshan, who got out of the car, glanced at each other and looked quite satisfied.

And a middle-aged man with black stubble, dark skin, medium height, and wearing a foreign military uniform walked down, and a smile appeared on his face when he saw this scene.

"Mr. Wang Ye, I have admired your name for a long time!"

"Prince Sattler has a very high opinion of you, and I am looking forward to meeting you!"

Then, he looked at Wang Ye who was standing there, and without hesitation, he was sure that this young man who was too old was Wang Ye, and Wang Ye strode forward, and the two sides reached out to shake hands in one go, and at the same time, the middle-aged man said with a smile on his face.

"I'm also looking forward to meeting you, and to quote a quote from the slogan below, our friendship lasts forever!"

"Welcome to the Red Star Machinery and Steel Complex!"

"Here, I send you my most sincere wishes, bless your country, bless our friends, and get the peace you want at an early date!"

Regarding Wang Ye's statement, the middle-aged man looked happy, nodded and said:

"Yes, it will!"

"This time, we will have our own peace and victory!"

"I am also grateful to our brother countries, Mr. Wang Ye, and Red Star Machinery and Iron and Steel Consortium for their important support to us that has begun or is about to start!"

"Our friendship will last forever!"

As soon as these words came out, Wang Ye waved his hand in one direction, and in an instant, a "bang, bang, bang" salute sounded, and along with the salute, countless pigeons took off with hula, covering most of the sky!

At that moment, the joy on the middle-aged man's face couldn't be suppressed at all, he held Wang Ye's hand hard, shook it vigorously, and then couldn't help but laugh directly.
