On the morning of mid-December, Zhang Kelongping arrived at Yonghan Aviation Technology Company by car.

Yang Jie also just arrived at the gate of the factory, and he greeted him with a smile: "Minister Zhang, let's go to the assembly workshop first." ”

"Let's go, take me to see what good stuff you've come up with again. ”

Zhang Kelong couldn't wait to drag Yang Jie inside.

The two walked into the assembly workshop side by side, and saw that hundreds of assembly workers in the assembly workshop were busy, and Zhang Kelong also nodded.

Looking at the past, Zhang Kelong saw that at least six engines of the Hengshan series and Kunlun series were being assembled, and Yonghan Aviation Technology Company at this time already had the same scale as Safran of France.

After a while, Yang Jie, Wang Yonglin and others accompanied Zhang Kelong to a final assembly line next to him.

Zhang Kelong's eyes lit up when he saw that there was a gourd-shaped engine with a horn spout on the assembly frame at this time, and hurriedly stepped forward.

"Yang Jie, this is the electric propulsion engine you developed?"

Zhang Kelong asked Yang Jie in surprise.

"This is the product of our continuous research and development in arc and electric heating for several years. ”

Yang Jie said: "Now this engine is a prototype that combines arc heating technology and electromagnetic technology, and we will carry out long-term technical tests after the assembly is completed. ”

At this time, Zhang Kelong saw that the assembly workers carefully installed a circular object with a diameter of more than ten centimeters and a length of more than one meter in a container, aligned, leveled, and set the position, and one of the workers first installed the precision positioning screw.

"What is this?"

Zhang Kelong asked.

"Minister Zhang, this is the arc heater developed by our company, there are a total of 12 heaters like this, and the temperature inside each heater can reach 3,000 degrees, because of the air convection design, the enthalpy value in the air can reach a very high level. ”

Wang Yonglin said to Zhang Kelong at this time: "Yang Shao proposed this technical solution, our company and other subsidiaries of Huaxing Group and some other research institutes to study, almost more than 10,000 engineers participated, it took more than four years to finally design and develop such a prototype." ”

"Yang Jie, you are really a genius technical solution!"

Zhang Kelong said.

"I just put forward an idea, and the difficulty of implementing it into specific engineering technology is many times more difficult than my idea, and all the technical teams involved in this project, such as Konstantin and Zhao Dexin, are amazing. ”

Yang Jie opened his mouth and said.

"Don't be modest, no one else has the idea of yours as you have the ability to organize so many technologists and spend so much money to do this. ”

Yang Jie smiled, this prototype has spent more than 3 billion dollars in the past four years, which is more than 500 million US dollars when converted into US dollars, and then it will have to be tested and verified and continuously improved, and it will cost at least hundreds of millions of US dollars to enter service with this engine, which may add up to close to one billion US dollars.

If it is placed abroad, it will cost at least five or six billion dollars to develop it.

Huaxing Group is now a major R & D project, in addition to its own engineering and technical personnel, can mobilize the resources of many domestic universities, research institutes, and a large number of domestic enterprises, at least 300,000 or 400,000 engineering and technical personnel can be mobilized to serve the R & D project.

Now domestic companies are proud of the cooperation with Huaxing Group Company, because cooperation with Huaxing Group Company can indeed benefit a lot.

Seeing the fan blades in front of the engine, Zhang Kelong said: "Yang Shao, how beautiful these fan blades are, they deserve to be the latest and most advanced blade design." ”

On the fan casing, a lot of engine accessories will be installed, including a large number of sensors, digital electronic control system part of the electronic components, as well as a large number of pipes and wiring, etc., there is a large permanent magnet motor in the middle to drive the fan and compressor, these bypass ratios and intake ducts are designed after very precise calculations.

Zhang Kelong was full of interest and asked this and that, "I really want to stay here all the time and watch this engine be assembled." ”

Yang Jie can fully understand Zhang Kelong's mood, the military has great hopes for Yonghan Aviation Technology Company, and is very concerned about the company's research projects, otherwise Zhang Kelong would not have come over immediately after receiving the call.

Next to this engine, Zhang Kelong also stayed for several hours, and when Yang Jie said to go to lunch with him, Zhang Kelong realized that he had been in the assembly workshop for several hours.

The next day, Yang Jiejie and Zhang Haiping had a phone call, and the latter was also very concerned about the design and development of the electric propulsion engine of Yonghan Aviation Technology Company, because in the future, this engine will be related to the design and development of more advanced hypersonic weapons and equipment platforms.

On the phone, Yang Jie gave a general introduction to the situation of his engine.

"Great, I'll make a special report to the Grand Chief. ”

With the strong support of the military, of course, it is the best, Yang Jie said happily: "Chief Zhang, with the strong support of the military, our confidence is even stronger." ”

Zhang Haiping laughed, and then said: "I want to take a look at the technical outline of your engine, further fully understand, and then report to the chiefs." ”

The technical outline of the engine design of Yonghan Aviation Technology Co., Ltd., which is set as Tianshan 100 internally, is naturally highly confidential and cannot be leaked in the slightest, but Zhang Haiping is not among them.

"Chief Zhang, there is no problem, you send someone to fetch it. ”

In order to keep it confidential, Yang Jie did not want to transmit it through the network, but took a more appropriate way and sent a reliable person to take it directly from Yonghan Aviation Technology Company, which would definitely be better.

Zhang Haiping nodded: "I'll arrange someone to come over immediately." ”

The efficiency of the military was undoubtedly very high, and the next morning, two plainclothes Bancun came to Yonghan Aviation Technology Company.

Through confirmation, Yang Jie knew that this was someone sent by Zhang Haiping, and one of them was still a major.

Wang Yonglin handed a USB flash drive to the major.

Yang Jie said with a straight face: "Major Wei, this is the information that Chief Zhang wants, it is top secret, you must hand it over to him in person." ”

"Mr. Yang, I know that the chief also personally explained before I came, so don't worry. ”

After speaking, Major Wei took the USB flash drive, and then signed to complete the handover.

He saluted a soldier driver before leaving Yonghan Aviation Technologies.
