Chapter 222 Boom 6AIT
“Let’s not talk about the software for now, I have another question.”
As a scholar, Lorenzo’s face is still relatively thin. Still wearing a slightly embarrassed look:
“I just noticed that in your numerical calculation results, the position of ice on the wing surface seems to be farther back and much higher than normal. , is that so?”
“That’s true.”
Chang Haonan nodded:
"Through our previous laboratory research, we found that it only takes about 0.001~0.1 seconds from the time the SLD collides with the airfoil to the completion of the icing process. This shows that The impact and freezing of supercooled large water droplets undergoes a more rapid and complex thermodynamic process, which is completely different from the mechanism in general research in which droplets of tens of microns first form a water layer and then undergo a phase change through two-phase heat transfer.”
< br>He also followed Lorenzo's question back to the technical discussion.
I have just finished what I want to say. Although it is impossible to achieve any immediate results, it can at least make the EU begin to feel the pressure and begin to feel that some Chinese companies are very concerned about this discriminatory policy. Dissatisfied and have tools to deal with it.
The underlying logic of everything in the world is common.
For example, if you seek peace through struggle, you will survive peacefully; if you seek peace through concessions, you will perish peacefully.
Struggle can be for peace, blockade can also be for communication -
Only when you can achieve reciprocal technical blockade, others will be willing to put down their posture and engage in equal communication with you.
This is why the simple "market for technology" route is unlikely to work.
“So this is the result you calculated using a new heat transfer and power model?”
"That's right, our software can handle various situations below 1000 microns."
Chang Haonan said, reaching out and patting the hummingly running server host next to him:
"Wait At the meeting, we will print out the 3D simulation diagram on the computer and send it to the three of us. When we get on the plane, you can observe for yourself whether the actual icing conditions match our calculated results.”
Lorenzo. He frowned, realizing that things were not simple.
During the first round of negotiations, Chang Haonan mentioned the need to create a new set of research methods and even a theoretical system.
But at that time, he thought it was the other party's research vision and something he wanted to work with them to complete.
The results now appear to be someone else’s research summary, and there is no need for foreign aid at all...
And the young man in front of me dared to say that he asked them to take the results and compare them on the spot. Obviously Very confident in accuracy.
Lorenzo even has reason to believe that the Chinese side may have already conducted 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 thought through a lot of intermediate content that did not exist, the final result was indeed correct.
Just show off your skills and your face!
However, this time he was very self-aware and did not continue to ask about the details. He just secretly calculated in his heart how big the gap between the two sides was in this field...
Instead, Colombo continued. Asked his doubts:
“By the way, Mr. Chang, you said before that the conditions we want to test this time are 400 micron water droplet diameter and -30°C temperature, but the last time we did the natural icing test flight At that time, I remember that it took more than two weeks to wait for the right weather conditions, and it is already the second half of February, and the weather in Hojing seems to be pretty good recently. Can we really encounter such harsh weather conditions? "
As a middle-level corporate employee from AgustaWestland, although Colombo has been in management positions for some years, he was originally from a technical background and knew very well that the test conditions mentioned by Chang Haonan were extremely difficult to occur even in the Great Lakes. Extremely bad weather is rare to encounter in other places for several years.
It was also true that the EMB120 was unlucky and happened to hit a cloud mixed with supercooled droplets and ice crystals.
"Of course that's impossible."
Chang Haonan was worrying about how to move the topic to the next part more naturally, but Colombo almost fell asleep after asking this question Pass the pillow:
“Actually, although SLD has a wide range, only supercooled droplets below 200 microns are more common. However, we have some new technical means this time, and we no longer need to follow the past Just wait for God to do his best. "The new technical means are..."
Colombo's tone was hesitant. He was not sure whether the other party would reveal so much information.
But this is what Chang Haonan was waiting for:
"It is useless to say more. Anyway, you have already obtained the results of the icing simulation. Next, I will take you directly to see our 'New technical means'."
Hearing these words, the other three people showed a somewhat surprised expression.
No one expected that Chang Haonan, who had always been wary of them, would be so easy to talk to this time.
"You three are coming 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 translators who were accompanying them, got into two military green 212 jeeps.
Ms. Valette in the back seat showed a look of pain.
On the way here, she was in great pain by this car with air leakage from all sides and no comfort.
"Chang, you can obviously produce aircraft like the MA-60, why don't you use the same energy to build a car that is at least more normal?"
Valette held the deputy in front of him tightly with both hands and said: Fighting the bumps, while complaining to Chang Haonan sitting in the passenger seat.
This question stunned the latter. In his impression, the European delegation's itinerary after arriving in Haojing did not include a test ride on the MA60.
"Ms. Valette has been on our MA60 before?"
Valette nodded and replied in a slightly louder voice than usual:
"At the Xiangzhou Air Show last year, I experienced it inside the cabin. Although it didn't take off, it was definitely much more comfortable than the current car."
"Is this..."
Chang Haonan For a moment I really didn’t know how to answer.
You can’t tell foreign friends that because our different industrial sectors are still relatively fragmented, it will take a long time for the technological achievements of the aviation system to be applied to the automobile industry...
In fact, China originally wanted to arrange a few better imported cars for the other party. However, the Science and Technology Commission considered that Haojing was not a particularly developed city at this time, and a group of wealthy people suddenly appeared on the street. The car meeting attracted unnecessary attention, so I simply gave up and transferred a few 212 cars in good condition from the 603 factory and the 172 factory to get rid of the problem.
"That's because we, Agusta, are responsible for all the cabin comfort and human-machine functional systems of the MA60..."
Fortunately, Colombo on the other side suddenly interrupted, and Valette did not Continue to struggle with this issue.
However, this topic also reminded Chang Haonan of what he had talked about with Minister Jin on the train home.
Originally, he was preparing to promote the Seiko Plan when he returned to the capital after the Spring Festival holiday. However, he was temporarily called to Haojing in the middle of the trip. The next few days were so busy that he almost forgot about it. Gone to the back of my head.
About half an hour later, the two cars finally drove into Factory 172 and stopped at the entrance of a final assembly plant.
"Then, please allow me to show you the most important equipment in this icing test."
Chang Haonan opened the car door and got out of the car first, pointing his hand towards the inside of the factory:
"H-6AIT."
