Chapter 157 Airworthiness Certification Must Be Done Yourself!

After obtaining the results of the most difficult basic research, Plant 182 was naturally able to complete the work of improving the de-icing system and wing structure design.

It is also an aircraft design and manufacturing group with a design department, and it is always impossible to ask outsiders for this most 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 ability is also tested.

As a result, several people have to face the same situation as when the previous turbojet 14 did the ground stability test - there is no test standard.

And this time it's not just that there are no domestic standards.

As mentioned earlier, in the mid-90s, everyone was relatively unrestrained in the treatment of aircraft anti-icing, and only the FAA, which had the best test conditions, had a set of anti-icing airworthiness requirements in the FAR-25 part.

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

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

"A few years ago, I heard a report from the engineer who led the team at that time, and the whole process was very bumpy, and I was often deliberately troubled by the other side, not to mention, and the verification process can be called ...... Danger is fraught. ”

"The content of their airworthiness test is also not perfect, many times it is based on the intuition of random weather engineers, looking at which cloud is more pleasing to the eye and getting in, as for the evidence of the icing and ice melting process, it is even similar to our local method, which is done with a few cameras fixed on the outside of the aircraft."

Chang Haonan shook his head:

"After all, the Y-12B is only a 5-ton, 20-seater, and 300-kilometer small aircraft, and it does not match the mainstream aircraft level, and the market prospect is very limited, so as long as it costs money, the FAA will not be too stuck, but this is not a long-term solution after all."

"Let's not say that the Y-8 is a military model, if we want to make planes that compete with Boeing for the market in the future, will the FAA continue to give us airworthiness certification?"

After passing the engine test of the turbojet 14 before, he finally passed the Commission of Science, Technology and Industry for National Defense to set up Huaxia's own aviation industry standards, and it is definitely impossible to go back to the Americans to do things.

But before Chang Haonan could further say his thoughts, Lin Guofan next to him couldn't hold back:

"Not only that, I have been studying air crashes in various countries around the world because of meteorological problems, from 94 to the present three years, there have been seven or eight air crashes in the United States alone due to wing icing, and there are no less than 100 accidents, and there is obviously a disconnect between the FAA's airworthiness requirements and the actual situation."

On the other hand, FAR25 only specifies what an aircraft "should do", but does not specify more specific "how it should be done", which is not clear enough for aircraft designers and pilots. ”

The latter, as a meteorologist involved in aviation to a certain extent, has the deepest understanding of this aspect of several people-

In many cases, when a person has studied too deeply in a certain field, sometimes they will ignore the macro vision of the entire industry, but interdisciplinary researchers will have some advantages in this regard.

"I think in the foreseeable future, we should be unlikely to sell the Yun 8 to the United States, and more importantly, the research we did during the previous period is exactly in this regard, I think we can refer to the FAA's requirements, combined with the actual situation of our country to make a more perfect, more instructive set of standards!"

Lin Guofan's eyes almost lit up when he said this.

After a person reaches a certain stage, there will always be some pursuits other than material things.

In fact, there are not too many opportunities to make a name for yourself in the field of traditional meteorology, and you still have to follow the general trend and participate in some key projects and projects.

And in the past half a month, he feels that he has at least found the right direction.

Ice formation simulations across the country and around the world!

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

If the thinking is a little broader, then the object of analysis does not even have to be limited to aircraft, high-rise buildings, power transmission lines, bridges and tunnels, etc. are all within the scope of his business.

It may indeed be a bit too much to say that it will go down in history, but it should still be expected to leave a strong mark in the industry and let your name shine in future textbooks.

It's exciting to think about.

Chang Haonan opened his mouth and looked at Lin Guofan on the other side who seemed to be caught in his own world with some surprise.

The other party has already told him everything he wants to say.

It's a perfect mouthpiece.

According to his experience, if a man shows that kind of fascinated expression, it is likely that he will be in some secondary and secondary dramas of YY, and he will become famous and even save the world or something.

No way, a man is a teenager until he dies, and it is not that he has never had anything like this before he was reborn.

The somewhat embarrassing atmosphere lasted for a few seconds, until Zhu Lan, who couldn't stand it, reached out and quietly twisted it around her husband's waist.

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

Liang Shaoxiu is still familiar with this set of gameplay in the aviation system, their 182 factory is now almost at a life-and-death juncture due to lack of funds and talents, if they can get such a remarkable project, it is bound to get some funding and policy inclination.

But after finishing speaking, he felt a little weak-hearted, such a big job, even if there was Chang Haonan and even Du Yishan's name as a guarantee, it was very likely that the superiors would not be at ease to hand it over to them.

So Liang Shaoxiu gritted his teeth again:

"If it really doesn't work, you can bring the 603 Institute in, as far as I know, according to the original plan, the MA60 project will also go to the United States next year to conduct airworthiness certification tests."

"Wait......"

Zhu Lan, who had been beside him and didn't speak just now, seemed to have heard something terrible:

"You said let Comrade Xiaochang be the first finisher? Wouldn't this be ......"

As a professor-level figure in the same mixed system, she is naturally clear about the twists and turns in this.

Although Zhu Lan now recognizes Chang Haonan's ability very much, in her opinion, if she wants to apply for a project above, it is better for the first person to complete it to hang 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 little too young anyway.

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

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

Then it becomes a self-bragging and it seems undignified.

So he quickly interrupted Zhu Lan's half-talk:

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

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

"Moreover, Comrade Chang himself is already the first person to complete or co-first to complete several key projects of the Science and Industry Commission."

There was a moment of silence in the meeting room.

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 genius younger generations we always thought were the real thighs?
