In fact, it is completely reasonable that everyone first thinks of Colombo.

After all, last time, he followed the prototype of the MA60 01 to conduct a natural icing test flight that met the requirements of Category 4 of the CCAR standard.

Whether it is from the experience of following the test flight, or the familiarity with the Huaxia testers and the test process, it is a good one.

Besides, the MA60 aircraft also has a share of your Fenmecanika Group.

So Colombo can't run anyway.

In fact, when he was in Agusta in the past, he had also tested the natural icing of many helicopters, and if he left the general situation, he might not be very afraid.

But the experience of following the whole flight during the last round of testing was so memorable that for a long time after that, Colombo's main nightmare was seeing through the porthole that the wings of the frozen aircraft outside had snapped due to violent fluttering.

And this time the weather conditions were even worse.

What's more, now that he has just been transferred to the parent company for a promotion and salary increase, he hasn't even had time to find a lover to be happy, and he really doesn't want to risk his life again.

It's hard to think about.

It is said that the good Chinese people all pursue the golden mean, and are not so adventurous?

For a few seconds, Colombo's expression was as sad and joyful as a change of face.

However, he also knew that the matter had come to this point, and if he still wanted to continue to mix in this industry, it was impossible for him to refuse.

"Ahem—"

Colombo moved his shoulders slightly unnaturally, and pulled a smile with difficulty.

Instead of being chased ducks to the shelves, it is better to volunteer:

"A few months ago, I completed a test flight of natural icing with the Huaxia team, and I also worked with Professor Lin, Mr. Chang, and Mr. Liang, so I should be one of the candidates this time, right?"

Chang Haonan They don't really care who follows, as long as what this person says after getting off the plane can convince the public, Colombo is still an acquaintance, so naturally there is no opinion.

When others in Europe saw that someone "volunteered" to undertake this task, they were even more desperate and immediately voted unanimously to approve it.

However, after saying a few words of thanks and so on, Colombo continued:

"Also...... The Huaxia side said that we can send two or three people to participate in the experiment, so for the sake of fairness, why don't we divide this opportunity equally among the representatives of our three parties? ”

This is said at a very high level.

First of all, he took the quota for this follow-up test as a rare opportunity, and proposed that the three main parties in the European delegation: JAA, Finmecanica and Airbus each get one-

Since you dragged me into the water, don't stand on the dry shore and get wet together.

Sure enough, the crowd who didn't think it was a big deal to see the excitement turned their eyes to Schneider and Valette next to them.

Unexpectedly, the former immediately made a big move:

"I have severe airsickness, and you saw it on the way here, so why don't you have Professor Lorenzo represent us at Airbus? He also happens to be an expert in the mechanics of broken bodies and fluid mechanics, and he can see more when he gets on an airplane. ”

Although Fernando Lorenzo is not young, his curiosity for the unknown has not diminished at all when he was young, and he is probably the only one among the people who really takes this time as a good thing, so he was very excited to hear that he was recommended, and if it were not for his status as a member of the negotiating delegation, he would probably jump up and agree.

Schneider, who had palpitations, finally put his mind at ease, and at the same time subconsciously raised his hand to loosen the tie knot.

The wave of Colombo's troubles just now almost made him breathless.

And Valette, the leader of the JAA over there, was not so lucky, her situation was similar to that of Colombo, she was only brought up not long ago, and she had not had time to establish her team and prestige, and besides, there was not a single scientific madman like Lorenzo who wanted to volunteer like Lorenzo, even if she named others, she would not go.

Everyone knows that even if the negotiations are successful, the main credit must go to the three team leaders.

Just kidding, what's the life of a few thousand francs a month?

"I agree with Mr. Colombo, so the JAA side is up to ...... I'll do it myself. ”

Therefore, in such a strange atmosphere, the European side was thus determined to participate in the flight test.

For the Huaxia delegation, the main purpose today is to get the Europeans to agree to participate in the subsequent test flight process.

Or, to put it more bluntly, give yourself a chance to show off your skills.

Now that the main purpose has been achieved, Huai Guomo has also begun to conclude his remarks and is ready to end this round of negotiations:

"In that case, then our second round of negotiations will be here for the time being, and if nothing else, the icing test will take place in three days' time, during which time we will send someone to take care of the trips of Mr. Colombo, Ms. Valette and Professor Lorenzo."

Perhaps because the negotiations went very smoothly on the whole, the old general was in a pretty good mood, and looked at the foreigners opposite and added:

"As for the rest of your staff, it is best not to go out alone for confidentiality reasons. If there is a real need, you can arrange some visits by our side, Hojing is the birthplace of our Chinese civilization, more than 8000 years ago, the first grandmother of the Chinese nation, Hua Xu Shi, the female leader of Hua Xu State, the hometown is in Hua Xu Town, Lantian County, Ho Jing, here is still the ancient capital of the Thirteen Dynasties, will not let you down. ”

Since this negotiation needs to hide from the FAA and even some forces on the Chinese side, this European delegation is not large in number and not very high-level, so it is easy to arrange.

In later generations, many places of interest and historic sites were not sold to the public in this era, and this is just going to work after the New Year, so there will not be many domestic units to organize visits, and they can be directly chartered.

……

Although Chang Haonan himself absolutely believes that there will be no problems with this test flight, whether from the perspective of aviation safety science or from the perspective of the three Europeans themselves, it is impossible to get on the plane to participate in this kind of risky test flight subject in a vague way.

Therefore, in the few days of waiting for the completion of the aircraft modification, the task of Chang Haonan and Lin Guofan was to introduce the preliminary work they had carried out in preparation for the test flight to Colombo and others without leaking secrets, so as to dispel the concerns of them, of course, mainly Colombo and Walette.

"Are you really not even going to do a wind tunnel test?"

Colombo looked at the calculation results given by Chang Haonan on the computer screen, although it was clearly stated that 5-10 minutes of level flight without opening the flaps under SLC conditions would only lead to a 22% reduction in the wing lift coefficient, and there was no risk of accident for the MA60 under light load, but the computer program in front of him was a black box after all, and it still couldn't make him completely relieved.

Chang Haonan called up the icing simulation program again, output a few parameters and let him start the calculation, and then turned around and said:

"Actually, Mr. Colombo, with all due respect, even if we do do wind tunnel tests, it doesn't make any sense at all."

"Professor Lorenzo should know that even the best NASA icing wind tunnel in the world can only create the limit conditions of 35 micron water droplet diameter, 50 m/s airspeed and minus 30 °C ambient temperature."

Lorenzo, who was next to him, nodded his head in agreement.

Chang Haonan then said:

"But the very harsh conditions we were going to test this time were 400 microns in diameter, 114 m/s airspeed (equivalent to 410 km/h) and -30 °C air temperature."

"So, wind tunnel simulation, whether you do it or not, it's actually the same, so let's take a look at our simulation results."

With that, he took a step aside with his hands behind his back, revealing the computer screen that had just been blocked behind him.

It's not the first time that Chang Haonan has run a few parameters just now, so the software only needs to spend a short time to retrieve the results from the database this time, and then render them into graphics.

However, the GPU of computers in this era is still too poor, and it is really troublesome to make a 3D module alone, so Chang Haonan simply left an interface and displayed the calculation results directly through CATIA's 3D modeling tools.

So what is shown in front of the three Europeans is actually a CATIA interface, but on it is clearly a simulation of the icing shape of the wings!

"This ......"

I saw Lorenzo, who had always been a scholar, as if he had seen a ghost, pointing to the screen in front of him and being speechless for a long time, and after a while he pointed to himself again, and then pointed to the screen again, as if the language module had been temporarily sealed.

Just when Chang Haonan was worried and curious, and hesitated whether to pinch the old gentleman's middle, Valette next to him spoke:

"Professor Lorenzo, does the software you develop still have this kind of functionality?"

The old professor finally regained his ability to speak at this time:

"I ...... I don't know, huh? ”
