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

Now, no truly qualified helicopter has been launched in the world. With the promotion of Cialek, the improvement of helicopters has finally shone with the glory of life.

These days, Cirick has been busy commanding the war on the Eastern Front. For him, he is mainly responsible for formulating strategies and tactics determined by the subordinate commanders, and will not interfere too much. He also believes that these powerful generals under him will not let him down.

Just after the helicopter inspection and made many suggestions for improvements to the helicopter, Cialek had not returned to his fortress and received another news that excited him.

"Head of Cialek, the reason why our armor-piercing bombs could not penetrate the Stalin tank was found." said Albert Spel, who is in charge of military production.

In the battle on the front line, Germany's new tanks were majestic and conquered cities and lands. The Soviets' main force T-34 has been proven to be a backward product and can only resist by sea-like quantity.

However, the new Soviet Stalin tank surprised the German tank soldiers. Germany's ace weapon, sub-caliber armor-piercing bomb, was ineffective against such tanks.

Fortunately, they seized an almost complete Stalin tank from the battlefield and immediately sent it back to the rear for research to the artillery experts of Henschel and Krupp.

"Their tank turrets are too inclined." As a representative technical expert of the military, Knepokamp also participated in the analysis. At this time, in the shooting range of Henschel, Knepokamp performed a detailed analysis through high-speed cameras and then replays.

The t-34 in the past was just ordinary tilted armor, but the current Stalin tanks have simply developed this tilt to the extreme and become a terrifying turtle shell.

The small space inside the turtle shell is a disaster for the big Europeans. Even if it is the Soviets, they have begun to find some small guys to be tank soldiers.

Now, the higher the hemispherical turtle shell, the greater the inclination angle, it is simply the smoothest elastic-avoiding shape.

In this way, when the armor-piercing missile flew over, it was directly bounced away like a water drift, causing a serious jump.

At the same time, this can also explain that advanced sub-caliber armor-piercing bombs are ineffective, but the blunt-head armor-piercing bombs used in the past can have a good effect because the blunt-head armor-piercing bombs have a positive effect, which can reduce the inclination angle and even become vertical injections.

However, this turret was cast too thick, and its blunt-headed armor-piercing bomb could not 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: "If the 88mm tank gun cannot penetrate, the 105mm tank gun is absolutely fine."

The development of German tank guns was upgraded in the order of 75, 88, and 105. Now Germany's main force is the 88mm tank gun, but the pre-research of 105mm tank guns has long been started.

"No." Unexpectedly, this proposal ushered in opposition from Alfred: "Our 105mm tank gun is still confidential, especially the processes such as electric slag-replenishing steel and self-tightening of the body tube proposed by Head of Cialis, which we have not yet mastered thoroughly and cannot be introduced yet. In particular, our army is equipped with a large amount of 88mm guns. If it is directly replaced with 105mm, our insufficient production will also bring great waste."

It is not that simple to change the caliber of the main tank gun. Now, the 88mm tank gun still has great potential. How can you replace it with a new tank gun when encountering a small twists and turns?

Germany's idea is not to brush the caliber.

Look at the Stalin tank, it uses a 122mm gun, with a large caliber and great power, but it has too little ammunition capacity and is too slow to load, so it is not suitable for tank use at all.

"Yes, we'd better improve on armor-piercing bombs. This difficulty will not stump us." Knepokamp said: "Analysis of the failure of tank shells to the Stalin tanks, I suggest submitting it to the Head of Cialis immediately. I believe that our head of state will definitely provide us with more appropriate ideas."

This is simply unbelievable. When the artillery experts present were helpless in the face of problems, they actually wanted to ask their heads of state to solve the problem. This was simply a shame for them.

However, they were proud that their heads of state were omnipotent. The first caliber armor-piercing bomb was proposed by Head of Cialis. The plan to use the bullet holder simply subverted their understanding. They were all old experts, but their admiration for Head of Cialis was definitely from the heart.

Now that they have encountered problems, they cannot solve them, and Head of Cialis must have a solution.

Of course there is a solution. Just when they had held two consecutive meetings and discussed the resolution, Head of State Cialis finally came.

The instructions were sent by telegram, with few words, only one short line:

Improve the tail wing structure and reduce the rotation of the elastic body.

With this instruction, Knepokamp slapped his head hard. It was so stupid. Why didn't he think of such a simple solution?

One sentence woke up the dreamer.

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

It's the shells that are rotating.

The self-transfer will stabilize the shells. This is a huge invention. When the musket was first used, it flew a hundred meters away. After rifling, the bullets rotated and the ballistics would be extremely stable.

From then on, until now, guns or cannons are almost always rifled and are stabilized by rotation.

There is nothing wrong with blunt-head armor-piercing bombs. After all, the bullet body is thick, but the current sub-caliber armor-piercing bombs are different. Its essence is shell-piercing armor-piercing bombs. The bullet body is slender and long. When it rotates, its stability will be reduced.

Objects with the same diameter but different lengths have the same rotation speed, the longer they are, the more unstable they are. Now, as German artillery experts want to further increase the aspect ratio, this disadvantage has begun to be highlighted.

On the other hand, when it comes into contact with the opponent's turret, the warhead rotates too fast and is more likely to be bounced away.

Once this reason is found, there will be improvement solutions.

Reduce the rotation of the bullet body, so that the chance of jumping can be reduced. Immediately test the production according to this idea!

This is the principle in later generations. The shell-piercing armor-piercing bombs are all stable shell-piercing armor-piercing bombs in the tail wing, because in later generations they were almost all smooth-bore guns, and there was no rifle in the barrel. When the shells were out, they were all stable by the tail wing, which was similar to bows and arrows.

However, for seventy or eighty years, NATO's main force was still a 105mm rifled gun. This gun also fired a tail wing stabilized shell-piercing shell. After flying out, this tail wing helped reduce its rotation and reduced the speed of hundreds of thousands of rpm to thousands of rpm.

In fact, the tail stable armor-piercing missile fired by the smoothbore gun does not not rotate when flying. The deflection angle of the tail can give the core a rotation force, and the rotation speed of the core is about a few thousand revolutions per minute.

It can be seen that thousands of revolutions per minute is the best rotation speed of the slender bullet body, which not only maintains stability but also reduces the possibility of jumping.

(There is also the saying of sliding elastic belt. The heroes of East China have not come into contact with many things. I hope that the familiar ones will solve their problems. I have done two more chapters of technicality. I hope everyone will not get bored.)
Chapter completed!
