This time, Chang Haonan's silent rectification is definitely a big job, and its impact naturally cannot be as simple as making Yan Zhongzhong choke on a mouthful of water.

It's one thing to design a single experiment, it's another to come up with a set of uniform regulations that can be applied to the whole industry.

"Make it up?"

Yan Zhongzhong, who had finally recovered his breath, gave up his intention to drink water, and opened the "Aero Engine Intake Distortion Test and Evaluation Method" in front of him.

He had to see how many things Chang Haonan had added to it.

"Classification ...... of Stability Reduction Factors"

"...... of Criteria for Evaluating Aerodynamic Stability"

"Numerical Calculation Methods in the Process of Aerodynamic Stability Analysis......"

"Influence of Experimental Factors on Distortion Characteristics ......"

"Comprehensive Evaluation of Aerodynamic Stability in the Engineering Design Phase ......"

“……”

"Shhhh

Of course, it was impossible to read all the documents of a hundred or so pages in a short period of time, but just by glancing at the table of contents, Yan Zhongzhong was already shocked.

Regardless of what the content looks like, just looking at the logic of this text is absolutely clear.

Because the ARP1420 and AIR1419 standards that were introduced (copied) in the first place were fundamentally not suitable for the aviation industry system of China, which was born in the Soviet Union and France, much of the content in it was very stiff and confusing, just as bad as a math textbook with a stiff translation and a lack of content.

The evaluation method written by Chang Haonan not only has a lot of practical content with strong guidance, but also corrects or redefines many inappropriate parts of the original standard.

"Xiao Chang."

Yan Zhongzhong finally took a sip of water peacefully, and then slowly spoke:

"I can't do anything about this thing you wrote, and I'm not qualified to give an evaluation, so I have to report it."

He is very aware that many of the specific contents of this method involve a lot of professional knowledge outside the field of overall aero engine design, and it is not enough to rely on himself.

And more importantly, it's the national military standard.

Even if it is not complete at present, it is a serious national standard, and once the content is written, it is necessary to guide all engineering practices in related fields.

In other words, if there is a new model of aero engine or gas turbine to do the intake distortion test in the future, it must be carried out within this framework, and even involve a series of work such as follow-up type certification.

At any time, the formulation of relevant national standards in any industry is followed by countless interest exchanges and bloody winds.

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

Therefore, whether from the technical level or the management level, a whole expert group is needed, as well as the endorsement of the Commission of Science, Technology and Industry for National Defense behind it.

"I know that."

Chang Haonan, who was sitting opposite Yan Zhongzhong, took out a bulging file bag from his bag, and when he opened it, there was a pile of unbound document paper inside:

"I've been preparing the relevant documentation and engineering data, but in order to make this method really convincing, we still have to do it on our turbojet 14."

"Of course, the intake distortion test of the turbojet 14 engine will still go according to plan."

Yan Zhongzhong picked up the pen in his hand and habitually knocked on the table:

"However, according to the general process, there will be a standard review soon after I report, and in order to ensure that the progress on both sides is not delayed, the on-site commander of the test still has to change someone."

He can still tell the priorities of things.

With the performance of the turbojet 14 in the past period, it can basically ensure that the test process is smooth, and there are not many things that need to be disposed of on the spot.

Therefore, it is even more necessary for Chang Haonan to prepare for the standard review.

"If you change someone......"

Chang Haonan also knew that he lacked skills, and the efficiency of taking care of both sides was even lower, so he glanced at Yao Mengna, who was sitting next to him and had been silent, and after a little thought, he gave his own answer:

"Let me come to my senior sister, she has also participated in the design and determination of standards for relevant experiments during this time, and she is the most suitable person besides myself and you."

It's definitely not a compliment to put Yan Zhongzhong with himself.

In fact, in the original timeline, before GJB/Z64-94 really formed the ability to guide, the only person in the whole of China who had relatively systematically designed the asthma test was Yan Zhongzhong.

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

"Little Yao ......"

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

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

The afterlife is terrifying-

Yan Zhongzhong secretly sighed in his heart, and nodded at the same time, agreeing with Chang Haonan's candidate:

"It's okay, just let her come, it's also a workout."

The two of you said a word, and directly arranged Yao Mengna clearly.

"Huh?"

The latter was originally just admiring the temperament that Chang Haonan inadvertently revealed when communicating with Yan Zhongzhong, but he never expected to suddenly eat melons and eat himself.

"Wait, what's that for me......"

Yao Mengna's first feeling when she learned of this decision was panic-

Why was I, a third-year doctoral student who was a mentor to my junior brother, suddenly sent to be the on-site conductor?

After all, such an arrangement not only means recognition of her, but also means that she has to bear huge pressure and responsibility.

It's completely different from just doing technical research.

"Xiao Yao, don't shirk this matter."

Yan Zhongzhong turned to look at Yao Mengna, who was still confused:

"You are all the future pillars of the field of Huaxia Airlines, to be good at and dare to take responsibility, the difficulty and risk of this test is not great, just let it be for you to practice."

The corners of Yao Mengna's mouth twitched slightly, and she said in her heart that there was no reason to use the key projects of the Science and Technology Commission to train a doctoral student, but Yan Zhongzhong had already said it to this extent, and it was impossible for her to refuse, so she had to nod and agree.

"Guaranteed to complete the mission!"

Although it is not out of her own will, with her serious character, since she has taken over this task, she will definitely do her best to complete it.

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

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

This stabilized her mood a lot.

"That'...... I'll go back and prepare now. ”

"Don't be too stressed, you can go to the control room tonight to simulate the test process, and if you have any questions, you can also come and ask me or Xiaochang."

Yan Zhongzhong, who saw the nervousness in the female doctor's heart in front of him, continued to joke half-jokingly in a relaxed tone:

"Otherwise, in two days, after the jury arrives, we may not have so much effort."
