Chapter 131

The tank adopts the track method, which is equivalent to giving the wheels an extended road, such as walking on the flat ground. At the same time, the track method also greatly increases the resistance of the tank, so the fuel consumption rate of the tank is much higher than that of ordinary wheeled vehicles.

On the flat ground, the resistance is not small. In the mud pit, the resistance is even greater. In the mud pit, you have to go uphill to get out, and the resistance is the greatest.

The 780 horsepower engine roared and tried twice without success. Qin Guan knew that he couldn't go up if he wanted to rely on his own power.

There was mud everywhere. Qin Guan stood on the tank and watched the leopard-2 tank rumble forward.

"Catch." the leopard -2 is upside down. When it comes to the front of the mud pit, a soldier throws the steel wire rope over.

"OK." Qin Guan looked at the wire rope whizzing. It was more than ten centimeters away from his car body. Therefore, he could only reach forward, pull the wire rope from the mud, and then hang it on the hook in front of his car body.

The mobility of the tank is very strong, and its ability to adapt to the terrain is far better than that of wheeled vehicles. At the same time, when the tank is off-road, it is often in trouble.

So the front and rear of the tank have hooks, ready for mutual assistance at all times.

Now, after hanging the hook, Qin Guan went back to the cockpit again. He wiped his hands on himself at will, cleaned the mud, and then started the engine again.

"Boom, boom." this time, the front and rear engines worked hard together.

In front of the leopard-2 tank, the engine emits black smoke, and the steel wire rope has been tightened. With great strength, it drags the tank falling into the mud pit behind, while its own engine is rumbling behind the T-72. The two tanks emit black smoke together. The T-72 is in the mud pit, struggling, struggling, and finally the front of the car comes out!

The leopard-2 tank is still working hard in front, and the T-72 tank behind is also working hard. The two tanks together. Finally, the rear body of T-72 also left the mud.

At this time, the tank was almost full of mud, and the tracks and load wheels turned yellow. After leaving the mud, the engine was finally relieved.

Come out!

"In terms of mobility, the chassis of leopard-2 tank is the winner." Mr. Zhu made a conclusion: "its engine power is large and its ton power is high. At the same time, its track is wider. From the driving experience, leopard-2 is easier to drive. When we recruit tank soldiers, we don't have to recruit small people completely."

Today's tanks are very compact, so it's necessary to be small to recruit tank soldiers. Just when driving leopard-2, Qin Guan's whole body was inside the tank, and he wouldn't feel suffocated. However, if he drove T-72, he wouldn't feel comfortable even sticking out his head.

The advantages and disadvantages of the two chassis can be seen at a glance. If the leopard-2 chassis is determined to be developed as the prototype, there will be a very important problem to be solved. Our own production technology must be able to produce an engine with sufficient power.

There are drawings and processes. Even if there is everything, it needs to be run in and really manufactured to check the gap. It is not easy to reach the same level as the original Hans.

That's all for the mobility test, and then it's time to test the firepower of the tank.

If you compare the caliber only, the 125mm gun of T-72 has a larger caliber. However, compared with the firepower of tanks, you can't just compare the caliber.

"1000 meters, 300 mm target." the atmosphere on the test field became tense.

Two tanks stand side by side. One kilometer away from them, two one square meter vertical targets are set up. There is a cross in the middle of the target. If you can hit the cross, you will hit the target accurately.

Compared with firepower, in addition to penetration, there is also accuracy.

Qin Guan didn't operate a tank. He could drive a tank, but he had to be a professional to fire.

"T-72 ready."

"Leopard-2 is ready."

"Fire!"

"Boom!" the 125mm gun fired first. At the muzzle, a golden fireball burst into bloom. Behind the fireball was rich black smoke. In front of the fireball, an armor piercing bullet opened its tail wings and flew out.

Then, the 120 mm gun also fired. Although it was fired later, when the flame at its muzzle formed, it was bigger than that of the T-72.

What does this mean?

Hans' tank gun has higher chamber pressure and stronger propellant!

The pressure in the gun chamber determines the efficiency of the tank gun. The higher the chamber pressure, the faster the shell will fly out. However, the higher the chamber pressure, the greater the bearing capacity of the gun barrel, which requires advanced metal smelting technology. Otherwise, it is proper blasting.

The 120 mm tank gun of leopard-2 tank has an internal bore pressure of more than 500, which still takes into account the problem of service life. The maximum bore pressure is more than 700, which is definitely an adverse figure.

When tank guns fire, everyone covers their ears. It has nothing to do with courage. If you listen to the sound of * guns all year round, your ears will be deaf.

Both of them are metal rod armor piercing shells. However, the integrated shell of leopard-2 has a longer core. Two slender cores fly in the air, with a distance of 1000 meters and less than one second.

When the bomb core collides with the target, there is a high-frequency oscillating sound wave that is unacceptable to the eardrum.

If you watch a movie or something, if you hit the other party's tank, it is a bang, and the other party's tank will catch fire. In fact, the fire is caused by the explosion of ammunition inside the tank.

If you only wear armor, there will be no other effect except the sound of collision.

БР The type 11 tail fin stable shelling armor piercing projectile came with a fierce roar. It was almost half a meter away from the central cross line, and the warhead was in close contact with the target.

At the moment of contact, the huge heat brought by the collision began to melt the collision part, and the warhead of armor piercing projectile also began to deform, but it still drilled inward with strong kinetic energy.

As it continues to drill forward, the speed is getting smaller and smaller, the contact point of the target and the hit position are melting inward, and the warhead is also deepening and deepening.

Finally, its head loosened and passed through!

However, the moment it passed, it felt that it had completely lost its strength and could not move any more.

The armor piercing bullet was stuck at the impact point. The front warhead was exposed, the rear tail was exposed, and the middle was stuck on the target. It looked funny.

"In this case, it can be regarded as having broken through." a crowd came to see the target and Zhu Lao said, "but obviously, its armor piercing ability is at the limit of 300 mm."

Look at the other side, the target of leopard-2 tank, a molten hole passed through, and the warhead has long disappeared!
