Chapter 158: Airworthiness certification must be done by yourself!

After obtaining the most difficult basic research results, Factory 182 is naturally capable of completing the work of improving the deicing system and wing structure design on its own.

The company is also an aircraft design and manufacturing group with a design department, so it cannot afford to rely on outsiders for such basic work.

However, this does not mean that the work of Chang Haonan, Lin Guofan and Zhu Lan has come to an end.

Because like all other aircraft design work, anti-icing capabilities also need to be tested.

So several people had to face the same situation as when the Turbojet 14 was doing the ground stability test before - there was no test standard.

And this time it’s not just domestic standards that don’t exist.

As mentioned before, in the mid-90s, everyone was relatively unrestrained in dealing with aircraft anti-icing. Only the United States Federal Aviation Administration (FAA), which had the best testing conditions, had a set of anti-icing and airworthiness regulations in the FAR-25 part. sexual requirements.

"As far as I know, the only domestic aircraft that has undergone systematic icing tests is the Y-12B, which was conducted in the United States in 1986."

Liang Shaoxiu gently stroked the stubble on his temples and said to the other three people sitting at the conference table:

"A few years ago, I heard the engineer who led the team give a report. The whole process was very bumpy. I was often deliberately made difficult by them. The verification process can also be said to be... full of dangers."

"The content of their airworthiness test is not perfect. In many cases, they rely on the intuition of random meteorological engineers to get into whichever cloud group is more pleasing to the eye. As for the evidence collection of the icing and melting process, it is even different from ours. The original method is similar, it is done with several cameras fixed outside the aircraft."

Chang Haonan shook his head:

"After all, the Y-12B is just a small aircraft of 5 tons, 20 seats, and a maximum speed of 300 kilometers. It is not in line with the mainstream aircraft levels. The market prospect is very limited, so as long as you spend money, the FAA will not be too stuck. But this is not a long-term solution after all.”

"Leave aside the fact that the Y-8 is a military model. If we want to manufacture aircraft to compete with Boeing in the future, will the FAA continue to provide us with airworthiness certification?"

Having passed the turbojet 14 engine test before, he finally established China's own aviation industry standards through the Commission of Science, Technology and Industry for National Defense. It is definitely impossible to go back to the Americans to do things.

But before Chang Haonan could further express his thoughts, Lin Guofan next to him couldn't hold it in any longer:

"Not only that, I have been studying air crashes that have occurred in various countries around the world due to weather problems. In the past three years from 94 to now, there have been seven or eight air crashes in the United States alone due to icing on the wings, and the accidents are even more "No less than a hundred times, there is clearly a disconnect between the FAA's airworthiness requirements and the actual situation."

"On the other hand, FAR25 only stipulates "what an aircraft should do" but does not stipulate a more specific "how it should do it." For aircraft designers and pilots, the guidance is not clear enough."

As a meteorologist who is involved in the aviation industry to a certain extent, the latter has the deepest understanding of this aspect among the few people——

In many cases, when a person studies too deeply in a certain field, he sometimes ignores the macro vision of the entire industry. On the contrary, interprofessional researchers will have some advantages in this regard.

"I think in the foreseeable future, we should be unlikely to sell Y8 to the United States, and more importantly, the research we did during this period is exactly related to this aspect. I think we can refer to the FAA's requirements. , and come up with a more complete and guiding standard based on my country’s actual situation!”

Lin Guofan's eyes almost glowed when he said this.

After people reach a certain stage, they will always have some pursuits other than material things.

In fact, there are not many opportunities to become famous in the field of traditional meteorology. You still have to follow the general trend and participate in some key projects and projects.

In the past half month, he felt that he had at least found the right direction.

Simulate ice accumulation patterns across the country and even the world!

As long as China's aviation industry continues to develop, it must cross the "safety" hurdle.

If the thinking is broader, the objects of analysis are not necessarily limited to aircraft. High-rise buildings, transmission lines, bridges and tunnels, etc. are all within his business scope.

To say that your name will go down in history may be a bit too much, but there is still hope that you can leave a mark in the industry and have your name appear in future textbooks.

It’s exciting to think about.

Chang Haonan opened his mouth and looked at Lin Guofan opposite him with some surprise, who seemed to be trapped in his own world.

The other party has already said everything he wants to say.

It's a perfect mouth substitute.

According to his experience, if a man shows that kind of intoxicated expression, it is most likely that he is in some YY secondary plot, where he becomes famous and even saves the world.

There is no way, a man is a young man until he dies, and it is not like he has never had sexual intercourse with something similar before he is reborn.

The awkward atmosphere lasted for a few seconds, until Zhu Lan couldn't stand it anymore and reached out to quietly pinch her husband's waist.

"If that's the case, I think we can let Dr. Chang be the first person to complete the project and apply to the Science and Technology Commission for a big project."

Liang Shaoxiu is quite familiar with this method of playing in the aviation system. Their 182 Factory is now almost at a critical moment of life and death due to lack of funds and talents. If they can get such an eye-catching project, they will definitely get some funds and policies. of tilt.

But after saying that, he felt a little guilty. For such a big job, even if Chang Haonan or even Du Yishan's names were used as guarantees, the superiors would probably not trust them.

So Liang Shaoxiu gritted his teeth again:

"If it really doesn't work, you can also bring in the 603 Institute. As far as I know, the MA-60 project will go to the United States next year for airworthiness certification testing according to the original plan."

"and many more……"

Zhu Lan, who had been silent just now, seemed to have heard something extraordinary:

"You want Comrade Xiao Chang to be the first person to complete the task? Will this..."

As a professor-level figure in the same mixed system, she naturally knows all about the twists and turns.

Although Zhu Lan now recognizes Chang Haonan's ability, in her opinion, if you want to apply for a project from above, it is best for the first person to complete the project to have a more influential name, so that the approval process will be much faster. .

Although she couldn't think of anyone in Factory 182 who could be called "influential," Chang Haonan in front of her was a bit too young anyway.

Of course Liang Shaoxiu next to him could also understand the meaning of Zhu Lan's words.

At this time, Chang Haonan must not be allowed to explain himself.

That would mean you are bragging and it would appear that you are not decent enough.

So he quickly interrupted Zhu Lan in mid-sentence:

"Professor Zhu, you don't know something."

"Comrade Chang's mentor is Academician Du Yishan."

"Moreover, Comrade Chang himself is already the first completer or co-first completer of several key projects of the Science and Technology Commission."

The conference room fell into silence for a moment.

Zhu Lan and Lin Guofan first looked Chang Haonan up and down, and then looked at each other in unison——

It turns out that the young genius we always thought was the real one?
