1959: Carrying the achievement system, she rolled

The fourth child's eyes were full of admiration. His sister was so amazing. If he asked who he admired the most in the world, there was no one else except his sister.

Xie Kui and Da Niu were much more direct, their faces flushed with excitement. This was not just a troop carrier, it was simply a mobile fortress.

"Its car body is designed with a radar reflection area. See, this part is flat. This can reduce the radar reflection area, making it appear much smaller on the radar than its actual size, creating an illusion and making people ignore its existence." Du Yimeng explained, pointing to the position on the front of the car.

Not only that, the body of the car is also coated with anti-infrared paint and a layer of matte paint.

The car is equipped with the most advanced device systems. Considering the weather in the south and the fact that this armored vehicle is airtight, she also installed air conditioning.

If there were no air conditioning, with the hot and humid weather in the south, the soldiers sitting inside would be roasted like cooked ducks, let alone fighting.

The current level of air conditioning is just in its infancy, but don’t forget that her major is mechanics.

The principle of air conditioning refrigeration is very simple. A compressor is used to compress the gaseous refrigerant into a high-temperature and high-pressure gas.

It is then sent to the condenser for cooling, where it becomes a medium-temperature and high-pressure liquid refrigerant, and then enters the drying bottle for filtration and dehumidification.

The medium-temperature liquid refrigerant is throttled and reduced in pressure by the expansion valve to become a low-temperature, low-pressure gas-liquid mixture. It then absorbs heat from the air through the evaporator and vaporizes, eventually turning into a gas.

Then it returns to the compressor to continue compression and recycles for refrigeration.

Hearing this, everyone's eyes lit up. Being able to escape the radar's eyes would increase its survivability on the battlefield.

They thought that even if the car was hot and stuffy, they would still be willing to sit inside. Unexpectedly, she even considered this little issue.

"Speaking of its track drive system, the front and rear carriage tracks have driving force, and a movable connecting rod in the middle transmits power to the rear carriage. This can increase their survival rate in the mountains." Du Yimeng said.

"Is this the reason why it can climb such a high hill without overturning?" asked the fourth brother. They had just witnessed its ability to climb.

"Well, if the armored vehicle's compartment is a whole, it will not be able to survive in the mountains and may even overturn. If that's the case, why do we still have armored vehicles? We might as well let you continue to use your feet." Du Yimeng said with a smile.

Then she thought of dividing the carriage into two, thus creating the front and rear carriages.

The welding of the entire carriage is very precise, and all the joints of doors and windows are coated with rubber sealant to ensure that the carriage has sufficient buoyancy in water.

"You are so smart that you can think of this!" The fourth brother did not hesitate to praise and flattered him clearly.

He used to think that this armored vehicle had a weird shape, but now it seems that it is very beautiful!

Xie Kui and Da Niu also nodded vigorously. The fourth brother’s sister was so awesome. Who could have imagined that?

At the same time, they were a little confused. The fourth brother's brain was similar to theirs. He was not very smart, but just average.

But why is his sister so smart? They have the same parents, so why is there such a big difference?

They are now very eager to see what the other brothers of the fourth brother look like?

Is he the same as the fourth child, or as smart as his sister?

"Every profession has its own expertise. This is what I do every day, just like you think about how to fight a war every day. I don't understand your tactics!" Du Yimeng said modestly.

"Haha!" The fourth brother and the others laughed. Their tactics could not compare with hers, but these words made people feel relieved.

Huang Yamin on the side glanced at Du Yimeng silently. He was very sure that Dean Du treated them differently in this way.

He still remembered that Chief Engineer Wan had said the same thing, and Dean Du responded like this: We all have the same head, why is your brain different from others?

He saw it clearly at that time, and Chief Master Wan’s face was full of despair.

"Have you seen this rubber track? Such a track can push the armored vehicle forward in the water." Du Yimeng pointed at the track and introduced it to several people. Who said that tracks can only be used on land? The same is true in water.

It can be said that everything on this armored vehicle has its own function.

"The front and rear carriages carry four and ten members respectively. There is a heavy machine gun mounted on top, which can carry tens of thousands of rounds of ammunition. There are also grenade launchers on both sides of the carriages that can fire smoke bombs and grenades." Du Yimeng said this with a look of satisfaction on his face.

She feels a strong sense of pride every time she designs a tank or an armored vehicle. To her, these are not just weapons and equipment, but also sharp swords that safeguard national defense.

She knew that the defense and military industry systems of future countries would be the most advanced in the world, but she wanted to advance this time with the effect of her little butterfly.

She suddenly remembered the solemn oath at the end of every awarding ceremony: I will sacrifice my life to ensure that the people are free from worries and the country is safe.

She has been striving for this and she hopes that one day she will be able to truly achieve it.

"Sister, I used to think that being uneducated was no big deal, but now I find it quite scary because I don't know what words I should use to describe you?" The fourth brother said seriously.

His sister was clearly in the research institute, but she was able to tailor an armored vehicle that was perfectly suitable for them over 2000 kilometers away. What's more, this armored vehicle was so awesome.

"People should keep learning throughout their lives. It's not your fault that you have a low level of cultural literacy, but it's your fault that you are unwilling to learn. The battlefield of the future will belong to information warfare. If your cultural literacy cannot keep up, you will not even be qualified to go to the battlefield." Du Yimeng said this and patted the fourth brother's shoulder meaningfully.

The fourth brother is young and strong now, and can climb up the ladder with his military achievements. If his knowledge cannot keep up, even with her pushing him from behind, he can only stop at the regimental level.

Everyone's future is in their own hands. If you don't work hard, others can't do anything for you.

"Sister, I understand what you mean!" The fourth child nodded vigorously. His sister was the smartest person in their family. It would be right to listen to his sister. He would go back and study hard.

Xie Kui and Daniu lowered their heads silently, lost in thought. This was the first time they had heard such words, but they felt that they were very true.

Huang Yamin on the side subconsciously straightened his chest. Dean Du asked him to read more, and he has always done so.
