The second round, the tungsten alloy armor-piercing projectile, was stuffed into the cannon chamber.
The original 100mm rifled gun armor-piercing projectile has a very poor performance. It uses a full-caliber armor-piercing projectile created by World War II technology. Its armor-piercing capacity is only more than 100 mm. When it comes to the battlefield, it faces various other tanks.
, almost a character who tickled people.
Therefore, although the tank gun exported by our side can use various shells currently in service, it also plans to sell our armor-piercing shells and make a big profit, which is also considered an advanced technology exported.
If you want to drill through the enemy's armor, the aspect ratio of the armor-piercing projectile is an important indicator. The larger the indicator, the better. On the smoothbore gun, you can use the sub-caliber armor-piercing projectile, that is, the diameter of the core of the armor-piercing projectile can be
It is much smaller than the diameter of the muzzle, so that this ratio can be easily increased.
On the smoothbore cannon, just add a support to the core to complete the launch of the shell.
After the shells flew out, they did not rely on rotation to stabilize, but on the wings at the tail to stabilize, which was similar to the bow and arrow.
However, the rifled gun cannot do it.
Because the rifled gun has rifle, after the rifle is restricted, the shell must rotate together inside the barrel under the restrictions of the rifle, and even if it is mounted on the bullet holder, it will rotate together.
As a result, the sub-caliber armor-piercing projectile had already broken itself in high-speed rotation before it was out.
If the aspect ratio exceeds 5, it is no longer possible to fire in the in-line barrel gun. Therefore, for a long time, this disadvantage restricts the development of the in-line barrel gun until the emergence of sliding elastic belts.
This is an outstanding invention. This sliding elastic belt is interspersed between the barrel and the core. That is to say, the rifled gun causes the shell to rotate and transmits the rotational movement to the sliding elastic belt, and the shell body of the shell
Although it also needs to rotate, its speed has been greatly reduced. After leaving the muzzle and unshelled, the tail wing will produce huge rotation resistance to rotation, so the rotation speed will be lower, so the rifled gun can be used.
Methods to launch sub-caliber armor-piercing bombs.
As our side imported a full set of 105mm shells, we naturally introduced this sliding elastic band technology. Then, it was natural to use the current 100mm tank gun.
Due to the chamber pressure, this 100mm tank gun is destined to be unable to compare with the 105mm tank gun. Therefore, the performance of this armor-piercing projectile will be worse than that of the L7 tank gun. If it is exported, it will also be
It will not pose a great threat to domestic self-use.
Besides, in the 1980s, the military industry had to transform, and almost everything had to be sold to make money. In the later stage, even the party dues were sold, not to mention such a small tank armor-piercing bomb.
.
This is also an important part of winning the 69 tank export contract. When it is time to show one's skills, you must show one's skills!
When the first shot was fired, the T-72 tank was still ahead, but when the second shot was fired, both sides fired almost at the same time.
If there is a high-speed camera inside the barrel at this time, you can see a wonderful scene. The high-temperature gas in the barrel is pushing the bullet holder forward. Under the squeeze of the rifle, the sliding elastic belt is rapidly
When rotating, the internal elastic core is only driven by the inertia of the sliding elastic belt, and the speed is greatly reduced.
Go forward, go forward again!
The two bullet cores left the barrel, threw away the bullet holder, and flew forward. At this time, the atmosphere of the competition on site had entered a white-hot stage.
"Grenade, hurry!"
"Aim, launch!"
Finally, there is a grenade. Grenades do not need to pay attention to a particularly high accurate head. As long as they hit the target, they can also destroy the target with a large area of killing radius. Therefore, the gunnerman almost aims at the approximate direction and then step on it.
The firing device was removed.
Almost after the third cannon ejected the barrel, the 69 tank was already running side by side with the T-72 tank.
"Quick, hurry!" Ali shouted loudly: "They are going to surpass us!"
Even if it was not the instruction of the Soviets, just out of the dignity of a tank player, I would never want to see my tank be surpassed. This is a spirit of always striving for the first place. Ali's car crew, in the entire army.
They are almost the number ones, and they have never been at a disadvantage in the confrontation.
Now, it’s actually overtaken by the 69 tank, that’s great!
The driver in front was also very anxious. The accelerator pedal under his feet had already been stepped to the bottom. However, amid the rumbling sound, the black smoke behind him was getting bigger and bigger, and the speed of the tank was still unable to rise.
"Accelerate, speed me up!" Ali shouted loudly.
At this time, after the shells were fired, he had already drilled out of the turret, facing the heat wave, and watched helplessly as the 69 tank began to surpass them!
When you are about to overtake, should you upgrade or downshift?
Young drivers with manual transmission will choose to upgrade, but found that after the upgrade, the engine will roar, and the speed will not be up. The old driver lowers the gear and pulls up the speed to achieve overtaking. As for automatic transmission,
No need to worry, the computer will automatically lower several gears to realize the driver's intentions.
Now, in the fourth gear, the engine is no longer powerful. Stepping the accelerator to the bottom is just to make the engine emit more black smoke. Therefore, the driver gritted his teeth and pushed it to the third gear. Now, the engine is finally no longer holding it in.
It was about to rise, and the speed was quickly raised. In the whistling of the supercharged, the T-72 tank was howling and began to exert force.
Continue to rush, chase, chase!
Switching to third gear, the speed has really increased! Ali looked at the tank over there, and the distance was shrinking, and he was happy. However, at this time, the temperature of the engine behind was getting higher and higher, with a low-end large accelerator, and the engine was not
The heat is hell.
A red light has already lit up in front of the driver.
"Report, the engine is hot." The driver shouted.
High engine temperature! In the desert, high engine temperature is a common phenomenon. The best way for them is to stop, even open the armor plate behind to let the engine cool down, and then turn on.
But now, in this fierce competition, how can I have such free time!
"Don't worry about it, keep accelerating. It's time to get off the sand dunes ahead. Don't loosen the accelerator and increase the gear!" Ali shouted loudly, while holding the device next to him tightly, waiting to welcome the upcoming fierceness.
Bumping.
If you lose this time, will you still have the face to see someone when you go back? The most advanced T-72 tanks are not as good as the upgraded products of the T-55 tanks that were fired from the East?
