Wang Ding didn't care and stretched out his hand, so Xie Huimin could only reach over and shake the other party's hand, and then, Wang Ding had already strode towards the self-propelled gun, drilled in, and studied inside.

Their Type 83 self-propelled howitzer has been studied for several years, and over the years, technical problems have emerged one after another, and everyone has a headache.

"The noise inside sounds small." Wang Ding first raised his first question.

Noises!

The self-propelled gun, which is now being tested, is so noisy that even if you put on a tank cap, it will make people's ears rumble, and after a long time, you feel that your brain is going to explode.

Various schemes have been used, including the use of soundproof materials to wrap the engine compartment, which does not work, and now, listening to this, the noise is an order of magnitude smaller, I don't know how the other party did it?

All kinds of technical problems they face are waiting to be solved.

"This problem has been studied since the design time, and it is called NVH." Qin Zhenhua said: "It's better to be sparse than blocked, it's useless to completely block it, it's better to consider how to transfer the noise of the engine away, and don't transmit it to the inside of the car body, otherwise, under the cavity effect, it will definitely be aggravated." ”

So that's how it was solved! Wang Ding, who listened, nodded again and again.

………

When the grassland city has begun to become bitterly cold, the desert is still hot.

All 69 tanks are slowly moving back in the desert, a total of ten 69 tanks, belonging to a fully formed tank company.

Company Commander Haider was sitting on the seat, leaning on his back, feeling the cool air from the air conditioner, and closed his eyes.

They completed a patrol mission and are now on the way back, the cruising power of this tank is also good, and they are constantly groping in actual combat, they can often drive for five or six hours, and most of the fuel consumption is used before they start to return.

Anyway, there is an air conditioner blowing in the tank, which is very pleasant, and if you go out, it will be a heat wave.

Haider felt a trace of warmth like this, they didn't know that at this time, just behind them, a Chieftain tank force was following and chasing!

The tracks of the tanks crushed the ground, constantly stirring up the yellow sand, and in the pursuing troops behind, the commander Husseini was looking through the sights with great interest, looking at the tank troops over there.

"Report, a sandstorm is coming." The gun commander on the side said.

In the desert, damn sandstorms are everywhere! Hosseini turned his sight in annoyance, looking at the sandstorm behind him that was high up and filling the entire sky, and couldn't wait any longer!

"Attention, full speed ahead, catch up and fire at the enemy's ass!" Husseini gave the order.

In the desert, the sand and dust stirred up by the tank tracks, as well as the black smoke of the engine, it is easy to expose the target at a long distance, and those T-55 tanks on the opposite side are very strange, obviously 100 mm smoothbore guns, which can actually blow up the armor of the Chieftain tank.

So, they have to be careful.

However, the 69th Tank Unit, which was now on the way, obviously did not care that there were pursuers behind, and the sandstorm behind would cover the shadow of the Chieftain's tank troops.

Sure enough, the tankman of a 69 tank, turned the turret and looked behind, but there was nothing behind but the yellow sand.

"Report, a sandstorm is coming."

"Damn sandstorms." Heider said in annoyance: "I have to clean the engine filter again, it's manual work again!" ”

In the desert area, the life of all kinds of engines will be greatly shortened, in the desert, the content of sand in the air is too large, after inhaling the engine, it will increase the wear and tear of the engine.

Now, if it is covered in a sandstorm, the engine will still be greatly affected.

"Boom!" Just then, suddenly, a loud roar came.

When he heard this, Haider was startled and sleepy, and he shouted loudly on the radio: "Report the situation!" ”

"063 is destroyed, we have the chief behind us!" A voice came over the radio.

"Attention, full speed ahead, return fire!" Hearing this, Haider immediately gave the order.

The tanker stepped on the accelerator to the bottom, and in order to increase the power, even the air conditioning was turned off, and the inside of the turret heated up, and one by one the 69 tanks turned the turret to the back.

Just like in the ancient cavalry era, when the cavalry galloped forward and turned back to shoot arrows, the 69 tank was still galloping forward, turning its barrel to the back and starting to shoot at the rear.

Generally speaking, tank engagements should try to avoid this situation, after all, the thickest tank is the front armor, and if it is hit from behind, as long as it hits, there is no possibility of survival, and it will definitely be blown up.

But now, there is no time to turn the hull, besides, the Chieftain tank uses a 120-mm rifled gun, which is hugely powerful, as long as it is hit, the front and the back, there is not much difference.

So, just like that, they continued to move forward at high speed while firing backwards.

The weight of the Chieftain tank is very large, so the maximum speed is much lower, and if the two sides start at full speed, the Chieftain will not be able to catch up with the 69 tank, and they will definitely be able to get out of the battlefield.

Next to the 063 tank, the 064 tank fired the first shell fiercely, firing on the move, the accuracy was very low, but after firing, it would give all tankers an unprecedented sense of security.

The driver in front was also running at high speed, and the yellow sand rolled up by the tank in front of him obscured his vision, and when he saw clearly the side of a sand dune in front of him, he pulled the operating lever sharply, but it was still too late!

His tank, the hull tilted, swept over the side of the dune at high speed, and then, in the high-speed movement, the tank flipped to the side!

69 tanks overturned! In the midst of everyone's exclamations, the tanka flipped over, with its tracks facing the sky, and the tankmen inside it were turning back and forth inside the tank, and their noses and faces were swollen from the various exposed parts.

The sandstorm, at this time, has also swept over, and the yellow sand in the sky has covered everything.
