Chapter 1223 Solving the Problem of Armor-Piercing Projectiles

The flight principle of the helicopter determines that its speed will not be too high, but its vertical take-off and landing, so that it does not need to use a dedicated runway, is a huge improvement.

And now, there is no truly qualified helicopter available in the world, and under the promotion of Cyric, the improvement of the helicopter finally radiates the brilliance of life.

These days, Cyric has been busy commanding the war on the Eastern Front. For him, he is mainly responsible for formulating strategies. The tactical aspects are determined by the lower commanders and will not interfere too much. Moreover, he also believes in his subordinates. These warriors will not live up to his hopes.

Just after the helicopter inspection was completed and many suggestions for improvement were made to the helicopter, Cyric had not returned to his fortress when he received another exciting news.

"Führer Cyric, the reason why our armor-piercing projectiles can't penetrate Stalin tanks has been found," said Albert Speer, who is in charge of military production.

In the battle on the front line, the new German tanks were majestic and attacked the city all the way, while the main force of the Soviets, the T-34, has been proved to be a backward product and can only be resisted by the number of the sea.

However, the Soviet Union's new Stalin tank surprised the German tank soldiers. Germany's ace weapon, the sub-caliber armor-piercing bullet, was actually ineffective against this tank.

Fortunately, from the battlefield, they captured an almost complete Stalin tank, which was immediately transported back to the rear and sent to the artillery experts of Henschel and Krupp for study.

"The angle of their tank turret is too large." As a representative technical expert of the military, Knipocamp also participated in the analysis. Playback, Knipocamp for a detailed analysis.

The previous T-34 was just an ordinary inclined armor, and the current Stalin tank has developed this inclination to the extreme, becoming a terrible turtle shell.

The small space inside the tortoise shell is a disaster for the big Europeans. Even the Soviets have begun to find some small people to be tank soldiers.

But now, this hemispherical tortoise shell, the higher the upward, the greater the angle of inclination, it is simply the smoothest shape to avoid bullets.

In this way, when the armor-piercing projectile flew over, it was just like a water float, and it was directly thrown away, and a serious ricochet occurred.

At the same time, this can also explain the ineffectiveness of advanced sub-caliber armor-piercing projectiles, but the blunt armor-piercing projectiles used in the past can have a good effect, because the blunt armor-piercing projectile has a positive effect, which can reduce the inclination angle and even become a vertical injection. .

But this turret is too thick, and the blunt armor-piercing projectiles on the side cannot penetrate it from the front. In this way, this Soviet tank posed a new challenge to the German technicians.

"It seems that we can only install our 105mm tank gun." A technician said: "The 88mm tank gun cannot penetrate, and the 105mm tank gun is absolutely fine."

The development of German tank guns is upgraded in the order of 75, 88, and 105. Now Germany's main force is 88mm tank guns, but the pre-research on 105mm tank guns has already begun.

"No." Who knows, this proposal has ushered in Alfred's opposition: "Our 105mm tank gun is still classified, especially the electroslag remelting steel and body armor proposed by the head of Cyric. We haven't fully mastered the self-tightening and other processes, and we can't launch them now. In particular, our army is equipped with a large number of 88mm guns. If we directly replace them with 105mm guns, our output will be insufficient, which will also bring great waste. ."

Changing the caliber of the main tank gun is not that simple. Now, the 88mm tank gun still has great potential. How can it be replaced with a new tank gun after a small set of twists and turns?

Germany's idea is not to brush the caliber.

Take a look at the Stalin tank. The 122mm gun was used. The caliber was large and the power was not small. However, the amount of ammunition was too small and the loading was too slow, so it was not suitable for tanks at all.

"Yes, we'd better improve on armor-piercing projectiles. This difficulty will not overwhelm us." Knipokamp said: "I suggest that the analysis of the failure of tank shells to shoot against Stalin tanks should be immediately submitted to I believe that our Führer will provide us with more suitable ideas.”

This is simply unbelievable. When the artillery experts present were helpless in the face of the problem, they actually thought of asking their own head of state to solve the problem. This is simply their shame.

However, they are proud that their head of state is omnipotent. When the first caliber armor-piercing projectile was proposed by the head of Cyric, the plan of using the bullet holder simply subverted their understanding. They are all old experts. , but the admiration for Führer Cyric is definitely from the heart.

Now that they have a problem, they can't solve it, and President Cyric must have a solution.

Of course, there is a solution. Just when they had been meeting for two consecutive days to discuss a solution, the instructions of the head of Cyric finally came.

The instructions were sent by telegram, not many words but a short line:

Improve the tail structure and reduce the rotation of the projectile.

Taking this instruction, Knipocamp slapped his head fiercely. It was so stupid. Why didn't he think of such a simple solution?

A word awakened the dreamer.

Why does ricochet occur? It has a lot to do with the opponent's turret structure. The inclination angle is large, and the shells are hit obliquely, which makes it easy to be bounced. At the same time, there is another reason.

It's the cannonball spinning.

Autorotation stabilizes the shell, which is a huge invention. When the musket was first used, it flew away a hundred meters away, but with the rifle, the bullet rotates, and the ballistics will be extremely stable.

After that, until now, almost all guns and cannons are rifled and stabilized by rotation.

The blunt armor-piercing projectile was nothing at all. After all, the projectile body was thick, but the current sub-caliber armor-piercing projectile is different. Its essence is a shelling armor-piercing projectile.

Objects with the same diameter and different lengths are more unstable when they rotate at the same speed. Now, as German artillery experts want to further increase the aspect ratio, this shortcoming has begun to become prominent.

On the other hand, when it comes into contact with the opposing turret, the warhead spins too fast and is more likely to be ejected.

Find this reason, there is an improved plan.

Reduce the rotation of the projectile, so that the probability of ricochet can be reduced. Immediately follow this idea to trial production!

This is the principle of later generations. Shelling armor-piercing projectiles are all shelling armor-piercing projectiles stabilized by the tail, because almost all future generations are smoothbore guns. There is no rifling in the barrel, and the gun is ejected.

However, in the past seventy or eighty years, the main force of NATO is the 105mm rifled gun. This gun also fires armor-piercing shells with stabilized fins. After flying out, the fins help reduce the rotation and reduce the Hundreds of thousands of revolutions per minute are reduced to several thousand revolutions per minute.

In fact, the tail stabilized armor-piercing projectile fired by the smoothbore gun does not rotate when it flies. The deflection angle of the tail can give the core a rotating force, and the rotation speed of the core is about several thousand rpm.

It can be seen that several thousand revolutions per minute is the best rotation speed of the slender projectile, which not only maintains the stability, but also reduces the possibility of ricochet.

(There is also the saying of the sliding elastic belt. The hero of East China has not been in contact with a lot. I hope that the familiar ones will greatly clarify the confusion, and I have done two more technical chapters. I hope you will not be bored.)

Now that you have the idea, let's start experimenting!
