The military-industrial scientific research system of the academic master.

In fact, it is completely reasonable for everyone to think of Colombo first.

After all, last time he followed the MA-60 prototype No. 01 for a natural icing test flight that met the Category requirements of the CCAR standard.

Whether it is from the experience of following test flights or the familiarity with Chinese testers and test procedures, they are all doing their part.

Besides, your Finmeccanica Group also owns the MA-60 aircraft.

So Colombo can't escape no matter what.

In fact, when he was in AgustaWestland, he also participated in many natural icing experiments of helicopters. If the normal conditions were ignored, he might not be too scared.

But the experience of following the entire flight during the last round of tests was so unforgettable that for a long time after that, Colombo’s main nightmare was seeing the ice-covered wings outside through the portholes due to violent tremors. Vibrated and broken.

But this time the weather conditions turned out to be even worse.

What's more important is that now he has just been transferred to the parent company and received a promotion and salary increase. He has not even had time to find a lover to have fun, and he is really unwilling to risk his life again.

It’s really hard to think about it.

Is it true that Chinese people all adhere to the golden mean and are not so adventurous?

For a few seconds, Colombo's expression changed from sadness to happiness.

However, he also knew that now that the matter was over, if he still wanted to continue in this industry, he would not be able to refuse.

"Cough-cough-"

Colombo moved his shoulders unnaturally and struggled to smile.

Rather than being chased away from the shelves, it is better to volunteer:

"I completed a natural icing test flight with the Huaxia team a few months ago, and I also worked with Professor Lin, Mr. Chang, and Mr. Liang, so I am one of the candidates this time. There should be no problem, right?" "

Chang Haonan and the others actually didn't care who followed him, as long as what he said after getting off the plane could convince everyone. Colombo was still an acquaintance after all, so they naturally had no objection.

Others on the European side were even more eager to see someone "volunteer" to take on this task, and they voted unanimously immediately.

However, after Colombo said a few words of thanks to everyone, he continued:

"In addition...China said that we can send two or three people to participate in the experiment together. So for the sake of fairness, why not divide this opportunity equally among the representatives of the three parties?"

This is very well said.

First, the quota for this follow-up test was regarded as a rare opportunity, and it was proposed that the three most important parties in the European delegation: JAA, Finmeccanica and Airbus would each obtain one——

Since you dragged me into the water, stop standing on the dry shore and get wet together.

Sure enough, everyone who was watching the excitement turned their attention to Schneider and Valette next to them.

Unexpectedly, the former immediately used his ultimate move:

"I have severe symptoms of airsickness. As you saw on the way here, why not let Professor Lorenzo represent our Airbus company? He happens to be an expert in body mechanics and fluid mechanics. You can see it even on the plane. More to come.”

Although Fernando Lorenzo is not young, his thirst for knowledge about unknown things has not diminished at all. When he was young, he was probably the only one among the people who really regarded this trip as a good thing, so when he heard someone recommend him I was so excited afterwards that if I hadn't taken into account my status as a member of the negotiating delegation, I would have jumped up to express my agreement.

Schneider, who was still frightened, finally felt relieved and subconsciously raised his hand to loosen the knot of his tie.

The wave of disaster in Colombo just now almost left him breathless.

Valette, the leader of the JAA over there, is not so lucky. Her situation is similar to that of Colombo. She was promoted not long ago and has not had time to establish her own team and prestige. Moreover, among the people she brought with her, There is no scientific madman like Lorenzo who is eager to volunteer, and he will not go even if he names others.

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

Just kidding, what are you doing with a few thousand francs a month?

"I agree with Mr. Colombo's opinion. Then I will participate in the JAA myself."

So in this somewhat weird atmosphere, the European candidates for the flight test were determined.

For the Chinese 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 goal has been achieved, Huai Guomo began to summarize his speech and prepared to end this round of negotiations:

"In this case, our second round of negotiations will be here for the time being. If nothing else happens, the icing test will be scheduled for three days. During this time, we will send special personnel to take charge of Mr. Colombo, Ms. Valette and Loren The itinerary of the three professors."

Perhaps because the negotiations generally went very smoothly, the old general was in a good mood. He looked at the foreigners opposite and added:

"As for other members of your staff, considering the issue of confidentiality, it is best not to go out alone. If necessary, we can arrange some visits together. Haojing is the birthplace of our Chinese civilization. More than 8000 years ago, the Chinese nation The ancestral grandmother of the Huaxu family and the female leader of the Huaxu Kingdom, her hometown is Huaxu Town in Lantian County, Haojing. It was also the ancient capital of thirteen dynasties, and you will not be disappointed."

Since this negotiation needs to be hidden from the FAA and even some forces in China, this European delegation is not large in number and not of a high level, so it is easy to arrange.

Many scenic spots and historic sites in later generations were not open to public ticket sales in this era. Moreover, this was just after the new year, so there would not be many domestic units organizing visits, so it was completely possible to book the venue directly.

……

Although Chang Haonan himself absolutely believed that there would be no problems with this test flight, no matter from the perspective of aviation safety science or from the perspective of the three Europeans themselves, it was impossible to get on the plane and participate in such a type of risk. test flight subjects.

Therefore, during the few days waiting for the completion of the aircraft modification, Chang Haonan and Lin Guofan's mission was to introduce to Colombo and others the preliminary work they had carried out to prepare for the test flight without leaking the secrets, and to dissuade them. Of course, the main thing was Concerns of both Colombo and Valette.

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

Colombo looked at the calculation results given by Chang Haonan on the computer screen. Although it clearly stated that level flight without flaps for 5-10 minutes under SLC conditions would only result in a 22% reduction in the wing lift coefficient. For light load conditions, There is no risk of accidents for the MA60, but the computer program in front of him is a black box after all, so he still can't completely relax.

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

"Actually, Mr. Colombo, with all due respect, even if we did do wind tunnel testing, it would make no sense at all."

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

Lorenzo next to him nodded, agreeing with this statement.

Chang Haonan then said:

"But the extremely harsh conditions we are going to test this time are 400 micron water droplet diameter, 114m/s airspeed (equivalent to 410km/h) and -30C temperature."

"So, wind tunnel simulation is actually the same whether we do it or not. Why not take a look at our simulation results."

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

This was not the first time that Chang Haonan ran the parameters just now, so this time the software only took a short time to retrieve the results from the database and then render them into graphics.

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

So what was displayed in front of the three Europeans was actually a CATIA interface, but it clearly showed a simulation of the icing shape of the wing!

"This……"

Lorenzo, who has always been a scholar, seemed to have seen a ghost. He pointed at the screen in front of him and was speechless for a long time. After a while, he pointed at himself again, and then pointed at the screen again, as if the language module was temporarily blocked. It's generally sealed.

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

"Professor Lorenzo, the software you developed also has this function?"

At this time, the old professor finally recovered his ability to speak:

"I...I don't know either?"
