Huaxia Power Research Institute.

In a huge laboratory, a sharp roar resounded.

Behind the observation glass, there was a huge jet of flame, and a series of rings of flames appeared.

Mach rings are when the burning jet of flame enters the atmosphere and expands directly, but the pressure of the airflow after expansion is lower than the atmospheric pressure, so it will be compressed again.

Supersonic airflow will cycle back and forth between expansion and compression. This process will form expansion waves and compression waves, which will meet and overlap during the propagation process to form a series of rings.

There is no direct linear relationship between the number of Mach rings and speed.

Only having Mach rings means that the supersonic standard has been reached.

Therefore, Zheng Houde and other people in the observation room were all brightly impressed by the tail flame.

"Continuous testing for a day, then ignition to start the test, you can complete the phased test." Zheng Houde looked at the flames, his tone was a little excited:

When Zheng Houde's emotions recovered, he turned to look at Chu Ze, and said very seriously:

"Chu Ze, you led an era."

"The result of everyone's hard work." Chu Ze shook his head, not complacent.

The turbojet project has never attributed the reason for the project's rapid progress to itself.

It is the efforts of predecessors that have created the present.

"Efforts do not represent results. Think about it. I begged for the turbojet at the beginning, but they just didn't sell it. Even if they sold it to you, it would be a castrated version." Zheng Houde's eyes were somewhat nostalgic.

As he said, he turned to look at Chu Ze: "I followed the teacher and did this project, and we failed in the end."

"You directly promoted our fifth-generation aircraft process." Zheng Houde's tone was full of emotion, and his face was flushed with excitement.

Only when the sky has been ravaged can we understand how rare the freedom of the sky is.

Zheng Houde has seen it all the way, so he naturally understands the meaning.

A project that has not seen hope for a long time has been pursued for four or five decades, but no results have been seen.

But now, the results are suddenly in front of Zheng Houde.

It makes him feel like a dream.

The preliminary test results of the turbojet did not cause a large-scale shock, after all, the project Chu Ze participated in was a confidential project.

However, with the submission of the preliminary test results of the turbojet, many people looked at this report with some disbelief.

For example, Guo Zhongjie from the Academy of Sciences was completely stunned when he looked at the report submitted in front of him.

"He did it in more than half a year?"

Guo Zhongjie's first reaction was to disbelieve it. After all, the foundation of the turbojet project was Chu Ze's research.

When did Chu Ze start researching materials? It was in August and September.

After the materials were researched, the turbojet began to go through the process, which took only half a month.

At most, it took more than half a year from the beginning of the materials.

In the past six months, the turbojet has been tested. Judging from the current test results, he is optimistic.

"If the turbojet is successful..."

Guo Zhongjie fell into deep thought, tapping the office wooden desk rhythmically.

Bang bang sound began to sound in the office.

The success of the turbojet means that the progress in other aspects must be accelerated, which means that the future sky will have an eagle belonging to China.

Xicheng entered the cold winter of the twelfth lunar month, and the weather began to get colder.

Chu Ze was also preparing to return to Yucheng. He still wanted to go back to Yucheng for the first year of his rebirth.

The test of the turbojet project is still going on. It can be used as a persistent test. As long as someone keeps an eye on some data, the daily routine power on and off test will be enough.

The workload is not as much as before, and as the general person in charge of the project, Chu Ze also has some time for himself.

'We finished shooting in Hengdian, rest for a week, and fly to Yunnan Province when they are ready. It's faster than expected. ’

‘That’s not bad. I’m also going back to Yucheng for the New Year. ’

Chu Ze looked at the message sent by QQ yesterday and replied after seeing it.

In Hengdian, Liu Xixi was looking down at the script and suddenly heard the message from Didi. She was stunned for a moment.

She immediately leaned over to her notebook and watched the message coming.

‘Don’t you have time? Can’t we go to Yucheng to play? Go fishing at your place?’

Liu Xixi’s eyes lit up and she typed quickly.

‘Sure. ’

‘Then it’s settled. ’

Liu Xixi replied quickly with an uncontrollable smile on her face.

Su Chang stepped in and looked at the expression on Liu Xixi’s face and was slightly stunned.

“Seven days of rest make you so happy.” Su Chang was a little curious.Asked.

"Of course, I'm going to travel, accompany me on the trip."

Liu Xixi said with a smile. Facing such a smile, Su Chang just lowered his head and thought about the notice and nodded.

"Okay, where to go." Su Chang took off his costume naturally and put it on the hanger.

"Yucheng."

Just Liu Xixi's words made Su Chang's face stiffen instantly, and he turned his head to look at Liu Xixi in an instant.

"You are not going on a trip, you are obviously using me as a cover." Su Chang was already a little afraid to think about it.

If Aunt Liu knew that she was helping her daughter to cover up her love, and she was chasing after her, she really didn't know if she would be torn into pieces.

Su Chang had a bitter face: "Can I not go? I still have a notice."

"No, you promised." Liu Xixi obviously would not let Su Chang change his mind so easily, and took Su Chang's hand.

Su Chang slapped his head in annoyance.

"I saw you were so happy, I should have reacted at that time." Su Chang regretted not finding out the trick earlier.

If he had found out the trick earlier, he wouldn't have had the chance to take advantage of it.

"Does your busy Chu have time?" Su Chang regretted it now, but it was useless. Instead, he asked curiously.

"He's going back to Yucheng for the New Year."

"You don't want to meet your parents, do you?"

Su Chang thought of this special time node and widened his eyes.

"How is that possible? I don't think he knows what I'm thinking."

"So you plan to get it done in one fell swoop?"

"It depends."
