1959: Carrying the achievement system, she rolled

"That bowl costs 1 cents." Ma Nan said quietly. There used to be seven or eight bowls at home, and a lot of plates and dishes as well. Now there are only two bowls and one plate left. If they are broken again, they will be gone.

"Manan, you are a loser. I have never seen a man more useless than you." Xu Meimei yelled at the top of her lungs. She wanted to continue scolding him, but he left with his two children.

She felt like she was punching cotton, and this feeling of powerlessness made her crazy.

Manan came out with his two children and sighed deeply. He used to argue with her, but when he saw that the children were frightened, he chose to remain silent.

He felt very sorry for his two children by letting them be born into such a family.

He doesn't want to just muddle through like he is now, but does he dare to work hard?

The Xu family is like a bottomless pit. Any good thing in his family will appear in the Xu family in the next second. The more powerful he is, the faster he will die.

This kind of life now is not rich, but at least he can still survive and his family will not starve to death.

"Dad, our noodles were taken away by grandma." Xiaoqing, the eldest son of Manan, said aggrievedly. He and his younger brother wanted to eat a pancake, but his mother scolded them for being greedy.

But as soon as grandma came, his mother immediately took all the noodles in the house to her.

Isn’t it said that mothers love their children the most? Why do their mothers love their grandmothers more?

"Dad will take you to dinner." Ma Nan brought his two sons to a state-owned restaurant and spent a long time to scrape together three cents and a food coupon.

He ordered a bowl of vegetarian noodles, and his two children ate it. He himself was still hungry, but he didn't complain at all.

Everyone must be responsible for what they do, whether it is him or Xu Meimei.

Watching the two children eating heartily, his thoughts began to drift away. If he hadn't met Xu Meimei, would he have been able to live an ordinary life?

……

At this time, Du Yimeng, in stark contrast to the depressed Ma Nan, was discussing the manufacture of artillery-launched missiles with Wan Ping.

As usual, she drew the blueprints while Wan Ping did the work. As for the others, they were all working overtime to test the Type 64 tank.

No one slacked off because of the appearance of 'Ms. Qiu'. Both the work attitude and the work progress were as orderly as before.

The missile's appearance, loading method, and firing method are similar to ordinary artillery shells. After being loaded into the artillery, it is fired from the artillery.

After leaving the barrel, the rocket engine on the missile starts to start, providing the missile with flight power and enabling it to reach a high-speed flight state.

The biggest features of this missile are its fast flight speed, high hit accuracy and resistance to interference.

To achieve launch and precise strike on targets, not only rocket engines but also guidance systems are needed.

Du Yimeng uses semi-active radio command guidance, which requires the shooter to continuously aim at the target and then correct the missile's route through radio commands.

The operation is a bit complicated, but it is the only way with the current level of technology.

With the development of technology, laser beam riding guidance became the mainstream, which is to control the flight of missiles by laser beams. The longest range is as high as six kilometers.

In 61, China's first laser was successfully developed, but it is still in the development and exploration stage.

In other words, there was no established industry, only experimental equipment and a few prototypes. Under these circumstances, she decided to use semi-active radio commands.

Whether in this era or in the future, gun-launched missiles have important tactical value in modern warfare.

As for its targets, tank armor and fortifications, they can be destroyed effortlessly.

Of course, it also has disadvantages, such as being susceptible to signal interference and having a large minimum distance.

However, there is a solution to this problem, which requires high-precision measuring equipment and a longer command transmission time.

As for the minimum distance being too large, it means that when the missile is launched, it needs to maintain a certain safe distance from the target, and this distance is the minimum launch distance.

You must know that the missile needs to complete a series of actions such as ignition, arming of safety and locking of target smoothly, otherwise it will explode before launch.

She also considered using infrared guidance, but this system is very sensitive to changes in ambient temperature and is easily interfered with by external factors such as smoke and dust.

These are the things that are most in demand on the battlefield. If they fail before they can even begin to be effective, what else can she do?

Of course, it also has advantages, such as the fact that it does not need to transmit signals, which means that it has good concealment and is not easily discovered by the enemy.

It can track targets quickly, but the tracking distance is relatively short and is only suitable for short-range combat.

After comparing the two, she decided on the former, which was also relatively expensive. If they were ever asked to develop a tank with a lower cost-performance ratio, they could use this one.

"Comrade Du, I find you are a genius!" After listening to Du Yimeng's story, Wan Ping looked at her with shining eyes.

After her design, the anti-tank missile attacks the target as if it has its own thoughts.

"Comrade Wan, please remove the word 'discovery', thank you!" Du Yimeng said lightly. With three thousand attribute points added, her brain is now very developed, and no matter how complicated the matter is, it is a piece of cake for her!

"Comrade Du, actually the person you should thank the most is me. Back when we were in college, I was the one who helped you with your lessons." When Wan Ping said this, he subconsciously straightened his chest.

No matter how smart the person in front of him is, he is the real genius because he made up the whole thing.

"Thank you!" Du Yimeng said with a wooden face.

When she first came into contact with mechanical knowledge, she knew nothing about it. In addition, she was unwilling to stay up late to study, which was why she was slightly weaker than others.

She felt that she was already very good, but just not as good as others, but he didn't care at all!

His tutoring method was just like chasing her life, as if he wanted to rip her skull open and stuff all the knowledge into her head.

"No need to thank me, we are friends!" Wan Ping said generously with a wave of his hand.

Du Yimeng: ...

It's her fault, she shouldn't say anything sarcastic.

"Um...I..." Wan Ping hesitated, with a little shyness on his face.

"Congratulations on becoming a father." Du Yimeng couldn't bear to see him like this, it was really an eyesore.

"Thank you! No...how did you know?" Wan Ping looked at Du Yimeng in disbelief. Apart from the couple, only Dr. He knew about this.

"It's written all over your face." Du Yimeng said in a faint voice.

Wan Ping: He felt that it was impossible for him to have his own little secrets in front of her.
