Dad Yang called.

Yang Tang naturally didn't dare to slack off, and immediately signaled Liao Wu and Ling Ya to silence, and then he connected the phone.

"Dad..."

Yang Tang just shouted, and the opposite side was thrown over, and then he spoke bitterly for eight minutes, and finally added a key sentence, "Come back immediately, have dinner, your Uncle Bao is here!"

Yang Tang listened to the busy sound, speechless and choked.

"What's wrong, Mr. Yang?" asked Liao Wan.

"It's fine, it's just that the decree has arrived, and I have to hurry back to eat. Yang Tang said this and walked out the door.

"Go back to eat?" Liao was stunned when she heard this, "You don't have a party at night?"

"Bullshit, my parents are the biggest!" Leaving the aftermath of these words, Yang Tang has disappeared.

Ling Ya couldn't help but sigh with emotion: "I didn't expect our Mr. Yang to be a dutiful son!" After a pause, he said, "But he said that he would release two title songs a week, isn't it credible?"

"Who knows...... Anyway, you prepare with both hands, I'll allocate more money to you this week, and try to collect a few good songs!" Liao sighed.

"I've saved it. Ling Ya nodded, "The key is that the thunder and the distance are behind you to make trouble, it's quite bad." ”

"Bear with me, there are more people who don't do a good job by themselves, who specialize in pulling others back, and harming others and themselves!" Liao Wu sneered, "Not to mention the business, even when foreign insults invade, are there still fewer Han Yi in our Huaxia?"

"It's a lot, thanks to more benevolent and righteous people, otherwise it's not impossible for the country to become a country!" Ling Ya followed Liao Yan's words and said an idle sentence, "Okay, I still have to go back to Zhang Luo of the Art Training Department, you are busy yourself!" After speaking, she also left directly.

When he returned home, Yang Tang really saw Bao Youxin again, not only him, this time Uncle Bao even brought his daughter and son-in-law. Fortunately, both daughters and sons-in-law are complete, otherwise Yang Tang would definitely not have a good face for Bao Youxin.

After entering the house, Yang Tang took the initiative to say hello to Bao Youxin, and met his daughter Bao Yun and son-in-law Dong Ziwei under the introduction of Yang's father, and then asked, "Dad, where is Mom?"

"Your mother is in the kitchen......

"Then I'll help!" Yang Tang turned around and wanted to leave.

"Don't worry, your Uncle Bao has some private things I want to talk to you about......" Dad Yang said with a solemn expression.

"Yes, yes, Xiaohong, sit down and talk!" After Bao Youxin finished this sentence with a smile, he turned his head and glared at Bao Yun and said, "Your aunt is busy in the kitchen, hurry up and help!"

Bao Yun, who was still muttering with her husband, immediately resigned: "Yes, yes...... Here it goes!" he said, getting up and walking around the couch.

Seeing this, Dong Ziwei hurriedly followed, and at the same time said to Bao Youxin: "Dad, I'll go too." ”

"Okay, okay, go!" Bao Youxin waved his hand and sent his son-in-law away, and wanted to talk to Yang Tang about business.

Yang Tang said noncommittally: "Uncle Bao, you can come to see my dad, I welcome it, but if you are speaking for some people, then it is best for us to have a one-on-one interview, and my dad does not need to be caught in the middle." ”

When Dad Yang heard this, he was immediately unhappy: "Stinky boy, how can you talk?"

Bao Youxin raised his hand to stop Dad Yang from continuing to scold, and nodded at Yang Tang and said, "It's okay, then let's talk in another place." ”

"Let's go to the terrace on the second floor, just the two of us!" said Yang Tang, getting up and walking towards the stairwell.

on the terrace.

Yang Tang and Bao Youxin leaned against the railing, Bao Youxin took out a pack of cigarettes, shook out half and handed it to Yang Tang.

"Thank you, Uncle Bao, I don't smoke!"

"It's good not to smoke, then don't smoke......" Bao Youxin saw the cigarette back in his pocket, "But your Uncle Bao and I have a smoking problem when I was in the army, and I can't quit if I want to!"

Yang Tang said disapprerovingly: "It depends on how determined you are...... If you can't even control your own bad problems, how can you control your own destiny?"

Bao Youxin was stunned for a moment, and then smiled bitterly: "You are right, hehe, you really don't accept the old man!"

"Okay, Uncle Bao, let's talk seriously!" Between the words, Yang Tang had already sacrificed the hood without Bao Youxin noticing, beware of someone eavesdropping, "I don't like to go around in circles, if you have something to say, just say it!"

Hearing this, Bao Youxin hesitated for a while and said, "The leaders above are considered to have convinced you, but they also suspect that you have other good things that have not been revealed, and they asked me to come here just to probe your tone!"

Yang Tang couldn't help but roll his eyes: "Uncle Bao, I'll let you have something to say, but don't be so straightforward, right?"

Bao Youxin spread his hands and said, "Then how do you want me to talk?" After a pause, he said, "Good thing...... Yes or no?"

Of course.

And it's just too much.

So Yang Tang didn't know where to start for a while.

The most important thing is that he is not a top leader after all, and does not know the most pressing needs of the country...... Is it science and technology, or martial arts, or gods, demons, and monsters?

Therefore, after being silent for a long time, Yang Tang stumbled a little and said, "Uh...... Uncle Bao, I don't quite understand what you mean by good things? Can you give an example?"

When Bao Youxin heard this, he almost didn't go from the terrace to the first floor: You don't understand what a good thing is, why haven't you spoken for so long?

"Uncle Bao, let's give an example, otherwise it's time to start the meal later. Yang Tang urged.

Now it was Bao Youxin's turn to be speechless. I'm talking to you about national affairs, but you're thinking about having dinner, is this really good? Fortunately, he complained in his heart, but he didn't dare to delay Yang Tang's time, for fear of missing the right thing: "If you want to talk about good things, you are like an aero engine, a battery with a large capacity and extraordinary endurance, a superweapon that can destroy the earth, and so on...... It's all good stuff!"

Yang Tang listened, and kept complaining in his heart: Is there still a super weapon? Is there a nuclear bomb that can destroy human civilization (no nuclear in this world) do you want it?

But if you really want to talk about it, on the earth of this world, small-scale armed wars abound outside of China, more frequent than Yang Tang's previous life, if you dig into the reason, it is precisely because there is no nuclear bomb in this world, the sword of Damocles hangs over the head of mankind, so countries will unscrupulously launch armed conflicts, and they will do it if they do not accept it.

In the previous life, there was a nuclear bomb on top, and all countries were afraid that a small conflict would become a big conflict, and when the world war started, as soon as the nuclear bomb fell, that is, there was no distinction between north and south, and people were old and young, and basically they all had to go to see God.

As for the aero engine, no matter in the previous life, it can be regarded as a short board of the Chinese aviation industry. Of course, the actual problem is not in the design and construction of the engine, but in the material of the core components of the engine.

Today's aero engines are nothing more than two kinds of turbojet turbofans, but if you really want to talk about it, these two engines are actually one kind, and the turbofan engine is just more than the turbojet with one more fan blowing in the back, as the so-called fire borrows the wind, so that the jet will be more powerful.

The problem is that a turbofan engine consists of a fan, a low-pressure compressor, a high-pressure compressor, a combustion chamber, a high-pressure turbine that drives the compressor, a low-pressure turbine that drives the fan, and an exhaust system. Among them, the high-pressure compressor, combustion chamber and high-pressure turbine are called "core engines"!

In the previous life, the overhaul time of the so-called "core machine" part of the fighter engine was 4,000 hours, while the overhaul time of the domestic core aircraft before 2010 was less than one-fifth, that is, less than 800 hours. This time, if it is in the time of war, is enough, after all, no fighter plane can stay in the sky for 800 hours. But the problem is that, in normal times, this time is a bit choking.

What is overhaul? That is, after the use time reaches 4,000 hours, all the parts of the core machine must be disassembled one by one, inspected one by one, tested to see if each part has cracks and other defects, if there are parts, it must be replaced, and then the core machine is assembled and continued to be used, but overhaul once, the service life of the core machine will be halved, that is, it will become 2,000 hours, and then overhaul after 2,000 hours of use, and become 1,000 hours...... And so on, basically after four or five overhauls, the service life of this core machine will come to an end.

That is to say, the service life of the core machine in the United States is about 7,700 hours, and the domestic ones are not to mention, at least the core machines before 2010 are all tears.

You know, warplanes don't fly in the sky every moment of every day. A fighter plane can spend about four hours a day in the sky, and it will basically reach the average in the sky. In other words, there are almost 1,500 flight hours in a year, and the core aircraft will be replaced in five years, and during this period, maybe a new generation of engines will be developed and produced, and people's air combat strength will naturally increase in a straight line.

And the domestic core machine, what is the gap with the United States? In fact, the casting material of the core machine is not as good as others. Originally, theoretically, the more fully the fuel that enters the engine, the more fully it burns, the greater the thermal kinetic energy will be, and the more bullish it must be...... However, the actual situation cannot but consider the heat resistance of the core machine.

It's like magic acid is very useful in chemistry and the chemical industry, but it must have a special container to hold and store. In the same way, the high temperature and high energy of aviation fuel must always have something to wrap it up and then discharge it in a fixed direction, which can generate the maximum kinetic energy, and in this process, the core aircraft is tested by high temperatures.

Not only that, the core machine must not only withstand high temperatures, but also have enough strength and hardness, as well as lighter weight, otherwise the core machine will be blown up after a few hours of burning, and then it will be a fart! Then the problem is, if you want to have strength and hardness, it generally has to be alloy, and the melting point of the alloy is lower than that of steel (1535), but the gas temperature inside the core machine can reach more than 1,600 degrees, that is to say, if the core machine is made of general two-dimensional alloys, I am afraid that the core machine has disintegrated before the take-off temperature of the fighter plane has been reached.

It is precisely because of this that the people of the United States have developed a single crystal material by themselves, so as to meet the requirements of all aspects of the manufacturing of core machine materials. Relatively speaking, China will lag behind in this regard, and the life of the natural core machine will not be long.

Yang Tang is more familiar with the problem of aero engines, even if Huaxia in this world has made great progress in material research compared with the previous life, but the life of the best aero engine is still less than half of that of the United States.

"You stinky boy, pretending to be silent, not speaking for a while, what do you think?" Bao Youxin teased consciously and interestingly.

"Ah~~ I just thought about it casually, but it really reminded me of a good thing. Yang Tang's cheeks, which were still slightly lowered, suddenly raised, "It's a battery formula, it's more advanced than the current one......"

"Formula?" Bao Youxin was stunned, "What kind of battery formula?"

"Lead-acid batteries. ”

I have to say that Yang Tang, who gave the answer, is also well-intentioned, and he finally found such a most rubbish high-tech in the handheld exchange list copied from the red queen, which can continue the current research on batteries by science and technology.

Relatively speaking, the aero engine material problem that he had been thinking about before, there are many materials in the exchange list that can outperform the single crystal materials made by the rice guys, but the problem is that even if the formula is given to it, it cannot be made with the existing technology barrel circumference.

To put it bluntly, it is the level of comprehensive disciplines, and every related discipline it contains must be above the level, and no one subject can come out of anything if it is weak, well, that's pretty much what it means.

If you insist on using new materials, Yang Tang can also directly exchange for physical objects, but which ambitious country will pin the casting materials of aero engines on a private person? Even if it has been determined that Yang Tang is a [humanoid self-propelled weapon]!

As for lead-acid batteries, they have been used since the twenties and thirties of the twentieth century, and because of their stability, they have been used until now, especially in the military field, but today, with the rapid progress of lithium-ion battery technology, military batteries in many countries have begun to replace lead-acid batteries by lithium batteries.

Bao Youxin obviously also knows something about batteries: "Lead-acid batteries? stinky boy, now they are changing to lithium batteries, do you know?"

"Uncle Bao, then it depends on the specific battery index to speak, right?" Yang Tang said indifferently, "At present, lithium-ion batteries can double the storage capacity of lead-acid batteries under the same weight, and this indicator has even reached 2.2 times (that is, the original 3.2 times) in the little devil." ”

"Hey, it seems that you understand it very well!" Bao Youxin smiled, "What about the battery formula you provide?"

"The volume of the battery is 47 times 407 (mm) square, the height is 1,003, the weight is 500 kilograms, the discharge capacity is 198,000 (AH) in one hour, the discharge capacity is 450,000 in 50 hours, and the battery life is seven years, and the cost is about three times that of the current battery of the same volume. ”

"What?!" Bao Youxin was shocked by the battery index, and at the same time, he couldn't help but snort.

You know, the current lead-acid battery has a discharge capacity of 15,000 in one hour, and 28,000 in 50 hours. What is the concept of hundreds of thousands of discharges? It means that a battery can make a submarine fully loaded for a day.

How many batteries are there on a general submarine (including nuclear submarines)? At least 200 batteries. That is, battery submarines alone can stay underwater for half a year......
