The spring cold is steep, and the sudden spring cold makes everyone put on the padded jacket they just took off again.

In those years, down jackets were not as popular as they were later, and most people's main clothing to protect them from the cold was still heavy padded jackets.

Qian Siming wrapped some of the dark green military coats on his body tightly, and took a few breaths into his palms to warm up.

"Why hasn't Lao Su come yet!"

I've been waiting for him at the bus stop for almost twenty minutes! Qian Siming thought in his heart.

"Old money!"

"Here!"

Su Che poked his head out of a black Santana and shouted, Qian Siming, who was standing in the cold wind.

"Bang!"

Qian Siming closed the car door forcefully, and asked a little incomprehensibly:

"Old Su, where are you taking me? Where did you get this car from? ”

Su Che, who was sitting in the driver's seat, smiled and said:

"This car was borrowed from the school, so we can count it as a tolerance today!"

As soon as Su Che said this, Qian Siming became even more curious, but he didn't continue to ask, but waited for Su Che to give an explanation.

While driving the car, Su Che looked at Qian Siming sitting in the back through the rearview mirror.

found that the other party did not continue to ask, and felt that he was bored, so he stopped hanging on the other party and said:

"I went to the Aerospace Research Institute in the north, and I heard that they had come up with a new material."

Qian Siming was even more puzzled after hearing this, the Rocket Research Institute is not ranked first in the domestic material industry at all, what is so good about the new materials they have made?

"What kind of new material they have come up with, it deserves such fanfare from you to see."

Touching the leather seat of the Santana 2000, Qian Siming asked with some doubts.

The school car is not easy to borrow, and if he didn't pay special attention to this visit, Su Che would not have been able to borrow this car.

"They have produced a new carbon-based composite material that is said to perform very well at high temperatures."

Su Che turned a corner, and then spoke.

"How good can the performance be? At best, it's okay to perform at 1200 degrees. ”

Qian Siming was a little disdainful, and he couldn't be clearer about how many catties and taels the Aerospace Research Institute had in the materials.

When Su Che heard the rebellious Qian Siming, he couldn't help but say about the contempt of the Aerospace Research Institute:

"I'm afraid I'll scare you to death if I say it! Their material performance is more than twice that of Eagle Sauce! ”

"And it's the latest data from the Eagle Sauce Minsuni Laboratory, and the data from the Rocket Research Institute is twice as high as theirs!"

"It can't be!" Qian Siming couldn't help but refute immediately.

"If you say that they are now at the advanced level in China, they are more credible than this! Lao Su, don't joke about these things! ”

Su Che didn't argue with Qian Siming too much, because he understood that there was no point in arguing about these things now.

As long as he sees the physical objects made by the Aerospace Research Institute, Qian Siming will be honest.

Santana galloped all the way and soon came to Qingjiang District, where the Rocket Research Institute is located, and the surrounding area of the Rocket Research Institute has not yet been developed.

Most of the land is still farmland, which of course will disappear in the following decades of urbanization.

Su Che parked the car on the side of the road outside the research institute, this car belongs to the Aerospace University, according to the confidentiality guidelines of the Rocket Research Institute, it will be more troublesome to drive in.

With Qian Siming, he walked to the gate of the research institute.

After handing it to the security personnel at the door and reading the letter of introduction from his unit, Cheng Wu, who was expressionless, looked at the head of the Aerospace University on it, and the steel seal on it that could not be forged, and then let them enter the research institute.

Su Che walked over according to the location of the director's office of the Rocket Research Institute in his memory.

Walking to the door of the office, I looked through the window of the office, and there was no figure of Zhang Xingyang in the office.

"Professor Su, Professor Qian? What are you doing here? ”

Holding a thick stack of drawings, Geng Bo pushed his glasses and asked with some puzzlement.

Su Che turned around and saw that the person who came was Geng Bo, and said a little happily:

"It's Geng Bo!"

"Let's come to Zhang Xingyang, do you know where he is? He doesn't seem to be in the office? ”

Geng Bo looked inside the office through the slightly blue glass, and Zhang Xingyang was really not there.

"Xingyang, if he is not in the office, he is probably in the materials laboratory."

"If you're not in a hurry, I'll take you there when I go to the drawing room to deliver the drawings."

Qian Siming nodded, indicating that he was not in a hurry, and said:

"We're not in a hurry, you go and deliver something first, we'll wait for you here."

Geng Bo nodded, didn't say anything more, but walked quickly to the drawing room on the second floor.

Su Che and Qian Siming watched him leave, Qian Siming turned his head to look at Su Che and asked:

"Lao Su, what is the specific situation with their materials? Did you understand? ”

Su Che no longer hid anything at this time, and said straight to the point:

"I also know this material from my daughter Xiaoxiao, who is now interning in the materials laboratory of the research institute. According to her, this material is a carbon-carbon composite material, which has a maximum performance at 3200 degrees Celsius and a strength of 412MPa!"

Qian Siming didn't wait for Su Che to continue, he directly interrupted the other party, his eyes narrowed and said:

"You're telling me science fiction stories here? If they make a material of this strength, I will eat it on the spot! ”

"Lao Su, don't be deceived by your daughter!"

Su Che smiled, not annoyed by Qian Siming's words, those who are familiar with Qian Siming know that this guy likes to bet with others, but he never seems to have won a bet.

"Old money, I won't gamble with you, I'm afraid you can't afford to lose!"

When it came to betting, Qian Siming instantly came up and swore and said:

"I'm not going to lose this time! I'll put it here, and if they do, I'll eat it on the spot! ”

Geng Bo happened to come back from sending the drawings at this time, and when he heard that Qian Siming, who had lost ten bets and ten losses, was betting with others again, he became interested in an instant:

"Professor Qian, count me in, I'll bet you to lose!"

Qian Siming naturally did not refuse to come, and when someone was willing to play together, he was even more excited.

"Good!"

Geng Bo heard that Qian Siming agreed to the gamble, and looked at Su Che and laughed.

A few people didn't waste too much time and went directly to the materials laboratory.

As soon as he entered the materials laboratory, Zhang Xingyang was fishing out a stack of carbon fiber cloth pieces that emitted a faint blue light from a puddle of liquid in the hot melt furnace.

The few people who pushed the door open and came in attracted all their attention as soon as they saw the material.

"This is the lining to be used on the combustion chamber?" Geng Bo was the first to ask.

Zhang Xingyang, who was still carefully throwing off the liquid on the material, looked up at the few people standing around him, and said casually.

"This is to be used on the nozzle, and the lining material in the combustion chamber has not yet been made, and there are no preparation conditions in our research institute."

Qian Siming seriously looked at the liquid that had just been soaked and asked:

"This is a silicon-based antioxidant coating solution?"

Zhang Xingyang only turned his senses from the materials in his hand at this time, and took a closer look at the person standing in front of him.

I didn't expect there to be people who knew a little bit, Zhang Xingyang thought in his heart and said:

"Sort of, but there's a trace of nano-metal nickel here, and something else."

After Zhang Xingyang's overnight efforts, the coating of carbon-carbon composite materials was finally completed, and the preparation process was completed at this time.

"Now that the preparation is complete, the next step is to do the performance test."

Zhang Xingyang looked at the people who were looking at him expectantly, and said a little speechlessly.

"Can you let me come?" Qian Siming looked at Zhang Xingyang's immature face and asked seriously.

Someone wanted to help him, but Zhang Xingyang was too late to be happy, he was almost tired after a busy night.

Moreover, Qian Siming, as a professor of materials science, has no problem at all when he does some material performance tests.

Zhang Xingyang sat slumped in his chair and looked at the three people who were busy in front of the thermo/mechanical high temperature tester that day.

Enjoying his rare rest time, just when Zhang Xingyang was about to fall asleep.

An exclamation suddenly sounded, interrupting Zhang Xingyang's opportunity to enjoy his cuteness.

"It can't be!"

"How is this possible!"

Zhang Xingyang rubbed his face, barely allowing himself to be a little more energetic.

walked to the front of the tester and looked at the experimental record sheet in Qian Siming's hand.

3200 degrees, 537MPa; 3600 degrees, 541MPa; 4000 degrees, 531MPa.

Compared to the previous semi-finished product, it has been graphitized and the surface has been coated with a complete body.

Not only is the high temperature resistance higher, but the strength performance is strengthened by about 20%.

"It's not too much different from what I predicted, maybe there are some problems with purity, it's a pity!"

Zhang Xingyang sighed and said a little helplessly.

The purity of materials in this era is a difficult difficulty that Zhang Xingyang cannot avoid, unless he improves the production of raw materials himself, otherwise this is already the limit.

Faced with Zhang Xingyang's Versailles remarks, Qian Siming was instantly a little annoyed:

"Do you know what this data means!!"

However, in the next second, Qian Siming remembered that the Versailles man in front of him was the one who made this material.

"Of course I know what that means, which means that our engine tail nozzles, which can withstand higher intensity and higher temperature impacts, can greatly increase the thrust of the engine."

Seeing the sleepy-eyed and yawning young man in front of him, Qian Siming suddenly felt as if he had witnessed the rise of a genius.

This young man, who has not yet reached the age of standing, is like a rising star, about to illuminate the dim sky of the material realm of the Dragon Kingdom.
