The Military-industrial Scientific Research System of the Academic Master Chapter 111

Chapter 111 Intake Distortion Test

This time, what Chang Haonan did quietly was definitely a big job, and its impact was naturally not as simple as making Yan Zhongcheng choke.

 It is one thing to design an individual trial, but another thing to come up with a set of universal and unified regulations that apply to the entire industry.

"Fill?"

 Yan Zhongcheng, who finally regained his breath, gave up his plan to drink water and opened the "Aeroengine Intake Distortion Test and Evaluation Method" in front of him.

 He had to see how much Chang Haonan had added.

 “Classification of destabilizing factors…”

 “Evaluation specifications for aerodynamic stability…”

“Numerical calculation methods during aerodynamic stability analysis…”

 “The influence of experimental factors on distortion characteristics…”

 “Comprehensive assessment of aerodynamic stability in the engineering design stage…”

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　ifier

Of course, it is impossible to read all the more than one hundred pages of documents in a short time, but just a glance at the table of contents has already made Yan Zhongcheng pinch his teeth in shock.

 Regardless of what the content looks like, the logic of the writing is absolutely clear.

Since the ARP1420 and AIR1419 standards that were introduced (copied) were fundamentally not suitable for China's aviation industry system that was born out of the Soviet Union and France, a lot of the content in it was very blunt and confusing, like a book Mathematics textbooks that are poorly translated and lack content are equally frustrating.

The assessment method written by Chang Haonan not only contains a lot of practical guidance, but also corrects or redefines many inappropriate parts of the original standards.

 “Xiao Chang.”

Yan Zhongcheng finally took a sip of water safely, and then slowly said:

“I can't do anything about what you wrote, nor am I qualified to evaluate it, so I have to report it.”

 He ​​is very clear that many of the specific contents in this method involve a lot of professional knowledge outside the field of overall aero-engine design, and it is not enough for one person to do it alone.

 And more importantly, it is the national military standard.

Even if it is not complete yet, it is a serious national standard. Once the content is written in, it will guide all engineering practices in related fields.

In other words, in the future, any new models of aero engines or gas turbines that need to be tested for air intake distortion must be conducted within this framework, and even involve a series of work such as subsequent type certification.

 At any time, the formulation of national standards related to any industry is followed by countless exchanges of interests and bloodshed.

Although China's aviation industry is completely under the unified leadership of the state and there will be no exaggerated plot of physical business war, this weight is definitely not something that Yan Zhongcheng, the model chief engineer, can handle.

 So whether from the technical level or the management level, it requires an entire expert group and the endorsement of the Commission of Science, Technology and Industry for National Defense.

 “I know this.”

Chang Haonan, who was sitting opposite Yan Zhongcheng, took out a bulging file bag from his bag. After opening it, there was a stack of documents that had not been bound:

“I have already prepared relevant documentation and data from the engineering design process, but if we want this method to be truly convincing, we still have to do it on our turbojet 14.”

“Of course, the intake distortion test of the turbojet 14 engine will still proceed as planned.”

Yan Zhongcheng picked up the pen in his hand and tapped the table as usual:

“But according to the general process, there will be a standard review soon after I submit the report. In order to ensure that the progress of both parties is not delayed, the on-site conductor of the test still has to be replaced by another person.”

 He can still distinguish the priorities of things.

 Based on the performance of the turbojet 14 in the past period, it can basically ensure that the test process goes smoothly, and there are not many things that need to be handled on site.

 Therefore, it is even more important for Chang Haonan to prepare for the standard review personally.     "If it were another person..."

Chang Haonan also knew that he had no skills at all times, and the efficiency of taking care of both sides would be even lower. Therefore, he glanced at Yao Mengna, who was sitting next to him and had been silent. After thinking for a while, he gave his answer:

“Let my senior sister come. She has also participated in the design of relevant experiments and the determination of standards during this period. She is the most suitable candidate besides myself and you.”

 Putting Yan Zhongcheng next to himself is definitely not a compliment.

 In fact, in the original timeline, before GJB/Z64-94 truly formed its guidance capabilities, the only person in China who had relatively systematically designed the asthma test was Yan Zhongcheng.

It's just that the water-spraying method he used was not as stable as the plug-in method later introduced from Russia, so it failed to become a standard in the end.

 “Xiao Yao…”

When he heard Yao Mengna's name, Yan Zhongcheng's first reaction was that she was a bit too young.

But immediately he realized that Chang Haonan in front of him was actually younger.

 The next life is to be feared—

Yan Zhongcheng sighed secretly in his heart and nodded at the same time, agreeing with the candidate proposed by Chang Haonan:

 “That's fine, let her do it, it'll be a bit of exercise.”

 The two of them made arrangements for Yao Mengna clearly and clearly.

"ah?"

The latter was originally just appreciating the temperament that Chang Haonan inadvertently revealed when communicating with Yan Zhongcheng, but he never expected that it would suddenly affect him.

 “Wait, why is it me...”

Yao Mengna's first feeling after learning about this decision was panic—

How come I, a third-year Ph.D. student who helps my junior fellow student, was suddenly assigned to be the on-site commander?

  After all, such an arrangement not only means recognition for her, but also means shouldering huge pressure and responsibility.

 It is completely different from simply doing technical research.

“Xiao Yao, don't refuse this matter.”

Yan Zhongcheng turned around and looked at Yao Mengna, who was still confused:

“You are all the future pillars of China Aviation. You must be good at and dare to take responsibility. This experiment is not difficult and risky. Just think of it as training for you.”

The corner of Yao Mengna's mouth twitched slightly, thinking that there was no point in giving a doctoral student practice skills under a key project of the Science and Technology Commission, but Yan Zhongcheng had already reached this point, and she could no longer refuse, so she had no choice but to nod and agree.

 “Guaranteed to complete the task!”

Even though it was not her intention, with her serious character, now that she has accepted this task, she will definitely try her best to complete it to the best of her ability.

So Yao Mengna looked at Yan Zhongcheng opposite, and then at Chang Haonan beside her.

 The latter's eyes seemed to be full of encouragement.

 This made her emotionally stable a lot.

 “Then...I'll go back and prepare now.”

“Don't be too stressed. You can go to the control room to simulate the test process tonight. If you have any questions, you can ask me or Xiao Chang.”

Yan Zhongcheng, who noticed the nervousness in the female doctor in front of him, continued to half-joke in a relaxed tone:

“Otherwise, after the review expert team arrives in two days, we may not have as much time to do.”
