At this time, everyone noticed Qin Zhenhua's unexpected approach, and everyone looked at Qin Zhenhua's movements, full of curiosity.

The water pipe was wrapped around the body, just compared and measured, Qin Zhenhua then enlarged it slightly, and then, skillfully used hemp rope, like weaving a basket, to weave the water pipe, and when it gradually revealed its prototype, Zhang Xiangqian reacted first: "This is a vest?" ”

That's right, what Qin Zhenhua made was a vest, and the entire water pipe was woven into a vest, the most common vest with two straps, and the water pipe was finally hung upwards into the suspenders of the vest, which looked indescribably strange.

"But what's the use of that?"

Wang Erzhu is still curious, he has followed Qin Zhenhua for the longest time, and he knows Qin Zhenhua's inner thoughts best, and now his invention and creation must be for tomorrow's competition.

Just, what does it have to do with this thing?

"If it's all there is, of course it's useless." Qin Zhenhua said: "What if, what if water is poured into this? Especially, with some ice water in it? ”

"I see!" Zhang Xiangqian patted his thigh: "With such a vest, you can directly cool down!" ”

When he said this, everyone understood.

Qin Zhenhua's invention is a way to overcome the scorching heat in a hot area.

If there is any inspiration, it must be the practice of the Soviets during the day, who doused themselves from head to toe with buckets before getting into the tank, trying to use the water to absorb heat as it evaporates and make themselves better.

However, it's too primitive.

This way is not comfortable, the wet body, when it evaporates, it is hot and damp, it will definitely be more uncomfortable, and this scheme of using water to cool down is still good, so Qin Zhenhua thought of it, wouldn't it be better if you put water in the water pipe and then wrap it around your body?

The tank soldier is inside the tank, stay for two or three hours, this vest can always provide a cooling effect, and when the tank soldier comes out, then the water in the vest must be discharged, and then replaced with ice water, you can continue to maintain combat effectiveness, anyway, every few hours, you have to refuel the tank or something.

"In this way, our air conditioner does not have to be turned on." Wu Ruihua continued: "In this case, we will still have confidence in the competition with the T-72 tank tomorrow!" ”

Originally, everyone was happy to defeat the T-55 today, but at the same time, there was also heavy pressure, after all, under Qin Zhenhua's agitation, the other party wanted to drag the T-72 out and compare it with his own tank.

That's a T-72 tank!

In World War II, the Soviet Union was able to win by relying on the tactics of the sea of tanks, the Soviet tanks were pushed all the way to Europe, and wherever the T-34 went, a sea of steel was raging.

After World War II, the Soviets have been quite yearning for this tactic, and the Soviets have developed a series of advanced tanks for this purpose, among them, the T-64 is impeccable in performance, and it is the trump card weapon at hand in the Soviet Union, however, the manufacture of this tank is complex, it is inconvenient to produce in large quantities, and they also need a low-end tank to create a numerical advantage to replace the T-55 tank that is on the verge of obsolescence, which is the origin of the T-72.

The unknown Kartsev of Nizhny Tagil withstood the pressure of his superiors, and used the way of exchanging the tanuki for the prince, under the pretext of the 172M project, came up with a new T-72 tank, although the General Directorate of Armored Forces was annoyed by this, but, it turned out that the performance of this tank was reliable and fully met the needs of the Soviet Army, so a generation of famous cars T-72 appeared.

It uses a body of six pairs of load-bearing wheels, the V-shaped wave shield in the front is its biggest feature, the driver is central, the rear is a cast spherical turret, the 125 mm tank gun is used, and the 780 hp turbocharged diesel engine is used.

At the same time, as a low-end tank in the high-low mix, it is also allowed to be exported in large quantities, and even export production lines are produced in other countries, so, like the T-55, the T-72 forms a large export family.

If the T-55 tank is placed in front of it, it can only be abused, and the 69 tank on its own side originally did not have any ability to confront the T-55 tank, but now, the work that Qin Zhenhua is working hard to do has paved a way for everyone to see the hope of victory.

Compared with firepower and protection, it is definitely incomparable, but, as today, if we compare mobility, we also have an advantage!

Our engine is only 580 horsepower, and the gap between the other party's 780 horsepower engine is very large, a world of difference, but the weight difference between the two tanks is not small.

The total weight of the T-72 tank is 41 tons, and the total weight of the 69 tank is less than 37 tons, which is more than four tons of weight, and in addition, the engine of the own side is improved, and the power loss in the high temperature conditions of the desert is not large, if the Soviets do not improve, their tanks may not be able to compare with their own in mobility!

However, if you want to fight for victory with all your might, then you can't turn on the air conditioner, and today you can abuse the T-55, turn on the air conditioner, and blow a cool breeze to abuse them, but if it is an abuse of the T-72, the power lost by the air conditioner must be taken into account.

If you don't need air conditioning, you have to find a way to cool down, Qin Zhenhua's liquid-cooled vest is a special equipment specially built.

"Come, let's do it together, Zhang Fei can also embroider, one per person." Qin Zhenhua said to several other people.

Tomorrow, rely on it to win by surprise!

Under Qin Zhenhua's greeting, Wang Erzhu, Zhang Xiangqian and Li Changjiang also began to move, learning from Qin Zhenhua's appearance to make their own cooling suits, while the other masters continued to carefully inspect the tank, so that the tank would have the best performance in tomorrow's comparison.

In the middle of the night, everyone fell asleep.

The heat of the desert area makes it impossible to sleep, and in the barracks where I live, the air conditioner makes a humming sound, which makes people even more irritable.

Qin Zhenhua lay there, closed his eyes, and couldn't sleep.

T-72, tomorrow, will see the T-72.

Qin Zhenhua understands this tank, and has read it in newspapers and magazines countless times, because it is exported, so the performance is not particularly secret, and many of its ideas are still useful for reference, such as automatic loaders, such as the idea of reducing the process to be mass-produced, etc.

We can learn from it, but if we are our own tank, completely mapping and copying it, it is probably not appropriate, after all, we are going to follow our own path.

Now the second-generation tank developed at hand, the storm tank of foreign trade, is just a transition, the final trump card in China, must be the third-generation tank, so, what will the motherland's future third-generation tank look like?

I'm looking forward to it.

With this expectation, Qin Zhenhua fell asleep.
