In a serious scientific attitude, Yang Weiping endured the shaking of the scan line on the computer monitor, and patiently and meticulously observed and recorded the test data and curve fluctuations of the WS8 verification machine on the external test platform.

Of course, the production plan for the mass production of WS8 Kunlun engines cannot be issued casually, otherwise it may cause major property losses to the country, which is a waste of resources and a waste of time.

After staying in the computer room for three hours, Yang Weiping asked Wang Chun to fill out the formal production plan.

★★★★★★★★★★★★★★★★★★★★

Without the old WS8's nearly ten years of research and technical accumulation, Wang Chun would not have been able to get the new WS8 out so quickly!

Yang Weiping sighed secretly in his heart, stretched out his hand and asked Wang Chun to pass the pen, and in the approval column of this production plan and task list, he signed the wild grass of "Yang Weiping" with three iron and silver hooks, and the date of February 14, 1980.

Thinking that tomorrow is the Chinese New Year's Eve, but Wang Chun and they don't seem to have any signs of a New Year's holiday. Yang Weiping couldn't help but ask with concern: "Elder Wang, tomorrow is the New Year, why haven't you arranged a holiday for cadres and workers?"

"A big leader like you is still busy with work. Of course, we also have to work overtime to carry out production raids. Wang Chun replied solemnly: "Everyone knows that if the WS8 cannot be verified earlier, the development and improvement of the Yun-10 and the 4-engine H-6 will not be able to carry out the follow-up progress." The New Year, every year, but Yun Ten and Bang Six. Can't wait!"

Yang Weiping felt a warm heart for no reason.

This is the Chinese scientists of this era! This is the Chinese people of this era!

When we have thousands of such dedicated, conscientious and responsible scientific researchers and industrial workers, they are the immortal cornerstone of the Great Wall of China's national defense industry!

Hearing is false. On the principle of seeing is believing, Yang Weiping, accompanied by Wang Chun, visited the various branches of Chang'an Aero Engine Research Center.

Everywhere I went, the atmosphere of the festival was very strong, but the enthusiasm and passion of the cadres and workers in the front-line jobs were even more energetic.

In the test workshop where the core machine group C was located, Yang Weiping actually saw Sun Zhengyuan, the director of the 908 Institute.

908 Institute, that is, the former Chang'an Semiconductor Materials Application Research Institute.

Since the institute has successfully developed the first third-generation nickel-based single crystal alloy in the world. It was directly classified by Yang Weiping as a national key confidential scientific research unit, and was greatly strengthened in terms of technical personnel and funds.

Sun Zhengyuan, an old scientist wearing an ordinary laboratory white coat, was of course stunned at first after arriving at Yang Weiping, and then he was elated.

"Director Sun. Why are you here?" asked Yang Weiping in surprise.

"Let's test a new single crystal material. Sun Zhengyuan pointed to a centrifugal blade machine running at high temperature on the workbench in front of him, and said happily: "Our 908 institute has already formed a pair of units with Lao Wang's research center.

Lao Wang: This is the core mecha, B, C three groups, is the best place for our new materials to test. A variety of different formulations of single crystal alloys, carbon fiber composites, and carbon/carbon composites require a variety of tests in the harshest environments, some of which are not available in our laboratory. ”

Yang Weiping nodded again and again while listening, "Mmmm, yes, yes, any kind of material that comes out of the laboratory and turns it into industrial application does require too many different test processes." Director Sun, what is the situation of this single crystal alloy that is being tested now?"

"In terms of high temperature resistance, compared with DZ58H alloy, it is only 7 degrees higher, and the effect is not very ideal. Sun Zhengyuan replied with a shameful face: "However, in terms of corrosion resistance, it is significantly stronger than DZ58H alloy." ”

"Is the preparation process complicated or simplified?" asked Yang Weiping with great interest.

"Simplified!" Sun Zhengyuan replied without hesitation: "And the production capacity of DZ79A can be increased by three times compared to the production of DZ58H alloy." ”

"In other words, this DZ79A is not only enhanced than DZ58H in terms of high temperature resistance and corrosion resistance, but also reduces the production cost by half?" Yang Weiping asked excitedly.

"To be exact, the production cost is only 35.5% of DZ58H alloy!" Sun Zhengyuan replied with a very affirmative nod.

"Old Sun, this is a great innovation!" Yang Weiping praised loudly: "The upgrade of single crystal alloy is not so easy, but as long as you can make progress on the basis of the original every time, it is a success!"

"Hmm!" Sun Zhengyuan nodded vigorously. He said solemnly: "Please rest assured Director Yang, now with the cooperation of Lao Wang's core machine development team, we have all the confidence in 908 within three years." A new single crystal alloy with a monthly output of 5,000 tons has been developed with a temperature increase of 15 degrees higher than DZ58H!"

"I'm looking forward to your success!" Yang Weiping bent his right elbow into a fist and gestured in front of his chest to cheer Sun Zhengyuan on.

"Director Yang. Tomorrow will be the Chinese New Year's Eve, are you coming to our Chang'an for the New Year?" Sun Zhengyuan asked enthusiastically.

"I want to too, but there are still a lot of things to deal with in the capital. Yang Weiping sighed and said, "Elder Wang." Elder Sun, I can only say sorry to you this year. ”

"It's okay, it's okay. A look of disappointment flashed in Elder Sun Zheng's eyes, and he shook his head again and again and said, "You are a busy person, and there must be a lot of things." ”

"On the day when our big plane successfully flies, I will definitely come to Chang'an to have a good carnival with everyone!" Yang Weiping made a very serious promise.

"Our big plane will definitely succeed!" Wang Chun and Sun Zhengyuan said in unison.

After coming out of the Chang'an Aero Engine Research Center, Yang Weiping took the opportunity to be in Chang'an. In the name of Spring Festival condolences, we walked around large state-owned enterprises and scientific research units such as Chang'an Aircraft Factory, Aero Engine Factory, and 908 Institute, and sent the care of the party and the state to the cadres and workers who are fighting in the front-line jobs.

……

The sound of firecrackers bids farewell to the old year. Ruixue welcomes the New Year one after another.

The land of China is full of joy, and every family is reunited.

The Xishan villa complex in the capital is an inconspicuous medium-sized courtyard house.

If you don't walk into this courtyard and see the owner, just by the ordinary and simple decoration style of the courtyard, it is difficult to believe that this is the home of the No. 1 leader, the supreme leader of China.

Since being accepted as a godgrandson by the No. 1 chief, Yang Weiping has not come here to eat when he was in the capital. But it was the first time that such an official Chinese New Year's Eve reunion dinner was held today.

In the hall, Ye Xiaoqiao wore an apron around his waist, talking and laughing with the old lady and several other women around the table to make dumplings.

In the bookstore, Yang Weiping chatted and laughed with a middle-aged man in his thirties, dressed very ordinarily, and sitting in a wheelchair.

"I said, Wei Ping, you've been in contact with the eldest lady of the Ye family for almost a year, right?" The middle-aged man happily stretched out his hand and pointed out, and said with a joking smile: "When are you two going to get married?" I have been waiting for this cup of wedding wine for a long time, otherwise I won't find a chance to repay your favor." ”

"Prepare for the engagement wine on the second day of the Lunar New Year. Yang Weiping put his arm on Erlang's legs, leaned on the sofa and replied very casually: "I haven't reached the legal age of marriage yet!" The central government has always called on young people to marry later and have children later. ”

"Although you are right, why do I think you don't seem to care about your marriage at all?" Uncle Fang asked half-jokingly and half-seriously.

"Uncle Fang, I'm only 22 years old this year!" Yang Weiping rolled his eyes angrily and said: "How can you get married at this age, according to my meaning, a man stands at thirty, and it is not too late to get married and start a family when he is thirty." ”

"Thirty years old, aren't you afraid that Ye Xiaoqiao will wait for you to be heartbroken?" Uncle Fang asked with a glare.

"Aren't I ready to get engaged to her first, make the relationship between the two parties clear, and let Grandpa and Grandpa Ye put their hearts in their stomachs!" Yang Weiping said with a sigh. (To be continued.) )
