"Let's not talk about the software, I have one more question."

As a scholar, Lorenzo's face is still relatively thin, and he still has a slightly embarrassed look on his face at this time:

"I just noticed that in your numerical calculations, the ice on the surface of the wing looks much further back than normal, and it is also much higher, right?"

"That's right."

Chang Haonan nodded:

"Through our previous laboratory research, it is found that it only takes about 0.001~0.1 seconds from the collision between the SLD and the wing surface to the completion of the icing process, which shows that the supercooled large water droplets impact the ice undergo a more rapid and complex thermodynamic process, which is completely different from the general research The mechanism of tens of microns of droplets first forming a water layer and then undergoing two-phase heat transfer to undergo phase transition."

He also followed Lorenzo's question back to the technical discussion.

Although it is unlikely to achieve any immediate results, it can at least make the EU begin to feel the pressure, and begin to feel that Chinese companies are already very dissatisfied with this discriminatory policy and have the means to deal with it.

The underlying logic of everything in the world is the same.

For example, if we seek peace through struggle, we will survive peacefully, and if we seek peace through concession, we will die peacefully.

Struggle can be for peace, blockade can also be for communication -

Only when you can achieve a reciprocal technical blockade will others be willing to put down their posture and engage in equal communication with you.

This is why the simple "market for technology" route cannot work.

"So this is what you calculated using a new heat transfer and dynamics model?"

"That's right, our software can handle a wide range of conditions down to 1,000 microns."

Chang Haonan said and stretched out his hand and patted the server host that was running next to him:

"Later, we will print out the 3D simulation on the computer and send it to the three of us, and when the time comes, you can see for yourself whether the actual icing situation matches our calculations."

Lorenzo frowned, realizing that it wasn't simple.

In the first round of negotiations, Chang Haonan mentioned that "a whole new set of research methods and even theoretical systems need to be created".

It's just that at that time, he thought that this was the research prospect of the other party, and he wanted to work with them to complete the content.

As a result, it now seems that this is the summary of someone else's research, and there is no need for foreign aid at all......

Moreover, the young man in front of him dared to say such a thing as letting them take the results and compare them on the spot, obviously very confident in the accuracy.

Lorenzo even had reason to believe that the Chinese side had already done many similar flight tests, and this time it was just a reenactment for them to show off their skills.

I have to say that although the old professor made up a lot of intermediate content that did not exist, the final result was indeed correct.

It's about showing off your skills and showing off your face!

However, this time, he was very self-aware and did not continue to ask about the details involved, but secretly calculated in his heart how big the gap between the two sides in this field was......

Instead, Colombo then asked his doubts:

"By the way, Mr. Chang, you said before that this time we have to test the conditions of 400 microns of water droplet diameter and -30 °C temperature, but the last time I did a natural icing test flight, I remember that it took more than two weeks to wait for the right meteorological conditions, and now it is the second half of February, and the weather in Hojing seems to be pretty good recently, can you really encounter such harsh weather conditions?"

As a middle-level enterprise from Agusta in the past, although Colombo has been in a management position for some years, he was a technical background in the past, and he knows very well that the test conditions in Chang Haonan's mouth are extremely difficult to occur even in the Great Lakes, and it is even more rare to encounter them in other places for several years.

It was the EMB120 that was unlucky enough to hit a cloud mixed with supercooled droplets and ice crystals.

"Of course it's impossible."

Chang Haonan was worried about how to move the topic to the next part of the content more naturally, but Colombo's question was simply sleepy and handed over the pillow:

"In fact, although SLD has a wide range, only supercooled droplets below 200 microns are more common, but this time we have some new technical means, and we no longer need to wait for the weather to be perfect, as we used to."

"New technical means refer to ......"

Colombo's tone was a little hesitant, he didn't know if the other party would reveal so much information.

But Chang Haonan was waiting for this time:

"It's useless to say more, anyway, you've already got the results of the icing simulation, so I'll take you directly to see our 'new technical means'."

Hearing this, the other three all showed expressions of surprise.

No one expected that Chang Haonan, who had always been wary of them, would speak so well this time.

"Three of you, come with me."

When leaving the computer room, the staff did not forget to give the printed simulation results to several people.

A group of five people, plus three special service personnel and an interpreter who accompanied them, got into two army-green 212 jeeps.

In the back seat, Ms. Valette looked pained.

On the way here, she was in a lot of pain by the car that leaked on all sides and had no comfort.

"Chang, you can produce an aircraft like the MA60, why don't you put the same effort into building a car that is at least normal?"

Valette grabbed the deputy in front of him tightly with both hands to fight the bump, and complained to Chang Haonan, who was sitting in the passenger seat.

This question stunned the latter, and he was under the impression that the itinerary of the European delegation after arriving in Hojing did not include a test ride on the MA60.

"Ms. Valette has been on our Boat 60 before?"

Valette nodded, and replied in a slightly larger than usual voice:

"When I was at the Xiangzhou Air Show last year, I experienced it in the cabin, and although it didn't take off, it was definitely much more comfortable than the current car."

"What ...... this?"

Chang Haonan really didn't know how to answer for a while.

We can't tell foreign friends that because the division of different industrial sectors is still relatively serious, the technical achievements of the aviation system will have to be delayed for a long time before they can be applied to the automobile industry......

In fact, Huaxia wanted to arrange a few better imported cars for the other party at first, but the Science and Technology Industry Commission considered that Hojing was not a particularly developed city at this time, and the sudden appearance of a fleet of luxury cars on the street would be unnecessarily eye-catching, so it simply gave up and transferred a few cars from the 603 Institute and the 172 factory to 212 in good condition.

"That's because all the cabin comfort and ergonomic systems of the MA60 are the responsibility of us at Agusta......"

Fortunately, Colombo on the other side suddenly interjected, and Valette did not continue to dwell on the issue.

However, this topic also reminded Chang Haonan again of what he had talked about with Minister Jin on the train home.

Originally, he was preparing to return to the capital after the Spring Festival holiday and began to prepare to promote the Seiko plan, but he was temporarily called to the side of Hojing halfway, and the following days were so busy that he almost forgot about it.

About half an hour later, the two cars finally drove slowly into the 172 factory and stopped at the door of an assembly plant.

"So, then, allow me to show you the most important equipment in this icing test."

Chang Haonan said and opened the car door to get out of the car first, stretched out his finger and pointed to the inside of the factory:

"Boom 6AIT."
