Chapter 190 Five Generations of Nickel-Based Superalloy Materials
?"High temperature alloy materials?"
"Yes, high-temperature alloy material. Do you know our country's latest fourth-generation fighter?" Qiao Yunfeng looked at Zhang Yang, put his hands behind his back, and paced back and forth beside the tea table, looking a little helpless and said.
"I know, there are two types now, black ribbon and black swan." As a college student and a boy, he naturally knows about these things.
"Yes, these are the two fighters. It can be said that the design of these two fighters is not weaker than that of advanced Western countries, but they still have a weakness, and that is the engine..." Qiao Yunfeng stopped at the table and sat down again, "Frankly
Speaking of which, our engines, whether in terms of thrust-to-weight ratio or quality stability, are currently not comparable to those of advanced Western countries. Do you know what the key to the problem is? In fact, it is the 195th generation nickel-based high-temperature alloy material engine.
High-temperature alloy materials used in blades and other components.”
"Currently, the engines used by mainstream fighter aircraft in the world are turbine engines, which rely on the pressure expansion process to achieve thermal power conversion and achieve the desired thrust effect. The size of this thrust depends crucially on the pressure ratio, and the other is how high the turbine
Front temperature. Theoretically, we can design an ultra-high pressure ratio and unlimited liters of turbine front temperature, but a key issue here lies in the quality stability of the blade and its endurance."
"The stability and tolerance of the blade depend on the high-temperature alloy used. Currently, in most Western countries in the world, the high-temperature alloys used are nickel-based high-temperature alloy materials. Western countries, especially the United States,
, the famous F119 engine uses the fourth-generation single-crystal nickel-based high-temperature alloy material epm-102. However, the second-generation nickel-based high-temperature alloy that is currently in practical use in our country is of course not impossible for us to design a product that is comparable to them.
alloy materials.”
"We can even produce high-niobium titanium aluminum alloy blades, but there is still a gap between us and Western countries in terms of technology and stability."
"Western countries have developed the thrust-to-weight ratio of turbofan engines to the extreme, and we can only catch up. Their engine thrust-to-weight ratio has reached 11, and now we can only
Sitting between 7.5-9, this is the reality of the gap."
"And your future father-in-law happens to be responsible for the research of high-temperature alloy materials. So, since you have mastered so many future technologies, you might as well help me come up with a set of awesome high-temperature alloys that are stable and can be put into production.
How about the technical data of the materials? Even if it’s not me, it’s still a contribution to the country.”
Qiao Yunfeng looked at Zhang Yang with a hint of urgency.
As for Zhang Yang, it's not that he doesn't want to help, but he only has eleven points now, which is still far from fifty points. Unless he loses points again, he can only ask the system and try his luck.
But in fact, when Qiao Yunfeng was just talking, he asked the system assistant about a set of turbofan blades that can allow the thrust-to-weight ratio of a turbofan engine to reach 13 or even 15. All the fifth-generation nickel-based high-temperature alloy materials used in it
Technical information will cost four;
He needs three hundred and twenty points, but with his current points situation, he can't even do it.
But of course, as long as you work hard, these things will be available in a few days.
He gritted his teeth. He deliberately chewed the word "high-temperature alloy material" and repeated it: "High-temperature alloy material? I haven't found any information similar to this in my head yet, but if you give me another week, I will definitely come up with one.
Set of fifth-generation nickel-based high-temperature alloy material production technology”
"One week?"
"Well, no matter how fast you go, you will have to give me at least four days." Zhang Yang gritted his teeth and said, forty points, now eleven points, and there are still twenty-nine points. For four days, seven to eight points a day, not that he
He couldn't stand it, but Lulu and Gao Qi were afraid that they wouldn't be able to stand it. Moreover, he was also worried that if this set of technical information was like that damn "first-level security defense system", what kind of future would it be used in?
Technology also costs points, which is a bottomless pit.
I'm afraid that if the engine doesn't come out, someone else will die first.
"No, no, it doesn't have to be so fast. I thought it would take a year and a half. I didn't expect you to make a set in a week. Isn't it too hasty? A month, maybe. If you can help me make it in a month,
Come up with a set of fifth-generation nickel-based high-temperature alloys... No, fourth-generation ones are also available. As long as we can produce high-temperature alloy materials with stable quality, you will be a hero of the country, and I will definitely ask for credit for you."
"Uncle, there is no need to ask for credit or anything, but I have a condition."
"What are the conditions? Tell me."
"That is, I can't let people know that these things are mine, including the words I revealed to him at night." Zhang Yang said, Qiao Yunfeng is his future father-in-law, and he is also a general, so even if he revealed some trivial things to him,
There should be no problem with the stuff, but if you let others know about it, you will be in big trouble in the future. If you don't save it, your head will be chopped off and used for research.
"So simple?" Qiao Yunfeng thought that Zhang Yang would ask to marry Qiao Xier to him, but he didn't expect to make such a simple request. Zhang Yang's secret, even if Zhang Yang didn't, he would not tell others that it was his own
My precious son-in-law, once he told me to go out, he wouldn’t let others snatch him away.
With a smile on his face, he nodded repeatedly: "I will never tell anyone what you said last night, but if you master the fifth-generation nickel-based high-temperature alloy material process technology but don't get any rewards,
It would be such a loss. After all, he is also my son-in-law, Qiao Yunfeng. I can’t watch my son-in-law suffer..."
At this moment, he had turned his prospective son-in-law directly into a son-in-law.
Zhang Yang was secretly happy in his heart, but said calmly: "Uncle, as long as you don't object to my being with Joyce, I'm very grateful. As for those rewards, they are nothing to me."
"Forget it, let's talk about it then." Qiao Yunfeng was so excited that he didn't know what to say. In this way, as long as a stable high-temperature alloy production process is obtained, not only can domestic high-thrust specific gravity engines be put into production smoothly,
It can even make China's most advanced fighter planes comparable to, or even worse than, the most advanced fighters of Western developed countries in the future.
Downstairs, the hostesses of Waju were sitting together nervously. Qiao Yunfeng's visit not only made Qiao Xier extremely nervous, but also Xu Danlu and Gao Qi were worried for a while.
The two of them have long regarded Qiao Xier as a biological sister, and they are also very aware of Qiao Xier's importance to Zhang Yang.
As for what kind of family the Qiao family is, they naturally know it very well. Of course, it is impossible for them to accept such a suave commoner like Zhang Yang who also has two girlfriends.
Qiao Yunfeng came over, and it was natural that he came with bad intentions. The two of them had been chatting on the fifth floor for so long. Qiao Xier and others, who had been waiting downstairs for several hours, almost rushed up to the fifth floor to take a closer look.
"Qiao Qiao, you said your dad is a general, right? I heard he was in the special forces, so wouldn't he be very good at fighting?" Gao Qi stood up with a pair of big breasts and stared at Qiao Xier with a worried expression.
, "Tell me, will he cripple Yangzi?"
"No way, my dad is not that kind of person..." Qiao Xier said uneasily in her heart. In fact, she didn't know what she was feeling. She vaguely remembered that when she was a child, she was bullied by a male classmate when she was in school. As a result, her father
I took a group of people directly to the door of the house...
When I was in high school, I heard that a boy was chasing me very closely. As soon as my father heard about it, he asked for leave in person and rushed back from the army to block the boy. I don’t know what my father did. Anyway, the boy came directly to me the next day.
Transferred school.
And this time... okay. Although my father seems to be easy to talk to, it is to himself, but if it is to outsiders, it is difficult to tell, especially Yangzi. If he thinks that he is the same as him, he will have his legs broken.
possible.
But just when they looked worried, and Gao Qi even went to find a stretcher, Qiao Yunfeng and Zhang Yang walked downstairs, arm in arm, like a pair of brothers, affectionately.
Qiao Xier and the three of them were petrified on the spot, especially Qiao Xier. She had already prepared in her heart how she would deal with her father and Zhang Yang if their relationship broke down, but she did not expect that these two people could walk together in such harmony.
Come down.
"Dad, you didn't do anything to Zhang Yang, did you?" Qiao Xier's eyes fell on Zhang Yang and kept glancing back and forth, for fear that this guy was missing a part.
"What are you talking about...what can I do to him?" Qiao Yunfeng was so angry at his precious daughter's words that he almost vomited blood. Your father is already an old man. It's not like you don't know that Zhang Yang is very good at fighting. It's better now.
Suddenly, I actually asked him if he was okay, instead of asking if there was any problem with your dad.
Sure enough, she is a female college student, her arms are turned outward.
"As long as it's okay, it's okay." Qiao Xier confirmed, and sure enough, not a single part of Zhang Yang's body was missing, and he even secretly glanced at her, which put a stone in her heart.
"Hmph, it seems that you don't want me to stay here, Qiao Qiao. That's all, I won't stay here tonight so as not to hinder you." Qiao Yunfeng pretended to be angry and glanced at Qiao Xier.
"Hey, Dad, since it's so late, you can stay if you want." Qiao Xier breathed a sigh of relief when she heard her father's tone. It seems that this stage has passed. At this moment, her
All my thoughts have been focused on Zhang Yang. How this stinky guy dealt with his father will have to be tortured later.
Qiao Yunfeng glanced at Zhang Yang speechlessly. He couldn't keep this daughter anymore. She could stay whatever she wanted. It was clearly an eviction order, but he didn't plan to stay here. It was said that all the girls here were beautiful girls, and he lived with a grown man.
What's going on here? Besides, I have to go back immediately to sum up the fifth generation single crystal nickel-based high-temperature alloy material technology. This is a qualitative leap. There must be a lot of basic work to be done.
"Let's go..." Qiao Yunfeng looked at Zhang Yang and said with a smile, "Zhang Yang, please remember the agreement between us."
"Don't worry, uncle!"
Qiao Xier was indeed heartless. As soon as she sent her father away, she immediately caught Zhang Yang and tortured him: "You...what did you say to my father?"
"Want to know?" Zhang Yang looked at her bulging peaks with a smile.
"Nonsense!" Qiao Xier looked at Xu Danlu and Gao Qi who were standing aside. After thinking about it, she gave up the idea of using force. "Tell me quickly, or you will suffer the consequences."
"No, unless you agree to me a condition." After all, it was obtained with forty points. Zhang Yang felt heartbroken for a while, and it would take more than ten battles...
"What conditions?" Qiao Xier looked at his confused eyes and knew that this guy must have bad intentions, but she really wanted to know the answer. (To be continued)
