From where the group got off the bus, you can already see that a medium-wing jet with a seemingly ordinary appearance is parked in the huge workshop.

The people here are all professionals, and even three Europeans always know the prototype of the H-6 Tu-16.

“AIT…… Icing simulator? ”

This time, Colombo was the first to react, and then showed a disappointed expression:

"This is your secret weapon?"

As a former employee of Agusta, Colombo had a lot of experience that people working on fixed-wing aircraft didn't.

This includes the use of various artificial icing methods to verify the helicopter rotor anti-icing system, so the icing simulation of aircraft is not new to him.

Valette, who was separated by mountains, showed a little curiosity.

In her opinion, the plane with pods under the wings is more like an air tanker.

Only the well-informed Lorenzo did not show any emotion, but just put his hands behind his back and looked up at the position of the rear of the refueling pod, which was supposed to be the refueling cone.

There is a bulkhead-style device installed there at this time.

Chang Haonan was not dissatisfied with Lorenzo's tone and expression.

He knew the truth of suppressing first and then rising, and the more the other party felt that this plane was ordinary now, the easier it would be to be shocked and drop his jaw.

"Mr. Lorenzo, this is no ordinary AIT plane, please come with me."

The group slowly walked into the final assembly workshop, and the modification of this bombing 6 was basically coming to an end, and only some necessary modifications were left to make the positions of the original tail gun shooter cabin and the communicator cabin.

"Rosie, you've probably seen that C130 modified icing simulator in the United States, right?"

Lorenzo, who was following Chang Haonan, asked Colombo next to him in a low voice in Italian, which he was not very proficient in.

The latter replied almost without thinking:

"Of course, the A109's rotor de-icing system was tested with the assistance of that aircraft."

"So what was the airspeed when you were testing it?"

Lorenzo has only heard about C130AIT, so he doesn't know a lot of details.

"Airspeed?"

Colombo was abruptly asked:

"Let me think about it, we don't pay much attention to this data when we test helicopters......"

Because the helicopter does not provide lift at its own speed, more attention is paid to the rotational speed of the rotor during the icing test.

After a few seconds, he replied in an uncertain tone:

"It's about 110 knots, which is about 205km/h......"

Hearing this answer, Lorenzo nodded thoughtfully.

"This is a specially developed injection device for simulated icing tests under SLD conditions."

The H-6 is actually not a very large aircraft, coupled with the design of the medium wing, so that Chang Haonan can touch the position of the refueling pod as soon as he stretches out his hand:

"The fully deployed side length is 1.5 meters, and consists of a total of 68 two-fluid micromist nozzles, which can spray a uniform water mist with an average particle size of between 25 microns and 1 millimeter at a maximum speed of 750 km/h and an altitude of 5,000 meters, with a deviation of no more than 20 percent."

Similar to Chang Haonan's previous expectations, as professionals, the three Europeans quickly understood after hearing the introduction.

Especially Colombo, who was still a little disappointed and disdainful just now, the corners of his mouth twitched a few times.

For a while, the whole workshop was only left with the sound of the motor when the power tool was started.

"Wait, wait, wait......"

Colombo finally realized why Lorenzo had asked himself those slightly obtrusive questions.

If he had read Mr. Lu Xun's writings, he would have expressed the following feelings:

"I'm so stupid, really, I only know that the United States has icing simulators, but I don't know that this one in front of me is even more awesome......"

This H-6AIT and the C130AIT he had seen before in North America can be said to be completely two levels of things.

The latter can only be used at low altitudes in a very narrow speed range around 200 km/h (the C130 has a stall speed of about 185 km), so it can only be adapted to the normal flight conditions of the helicopter.

The test object of the Huaxia this time was a serious fixed-wing aircraft.

Previously, they set the test condition for an airspeed of 114 m/s, which is more than 400 km/h.

And according to Chang Haonan, the aircraft can even work at speeds of up to 750km/h.

If this data is not particularly exaggerated, then let alone a propeller aircraft like the MA60, even the icing test flight of a jet aircraft can be completed with this aircraft.

After all, according to past experience, wing icing mostly occurs at low and medium altitudes and low speeds, and there is basically no need to consider ice damage in flight conditions exceeding 750km/h.

That's pretty impressive.

"Mr. Chang, at a temperature of -30°C, won't the water in the pipeline freeze?"

Vallet, who was next to him, as a representative of JAA, didn't quite understand these specific technical details, and just asked instinctively.

But this question is right in Chang Haonan's arms.

"Ms. Valette asked a good question, and that brings us to our exclusive technology."

As he spoke, he patted the shell of the refueling pod, making a crisp sound:

"As I said, this injection device consists of 68 two-fluid micro-mist nozzles, that is, nozzles that can spray gas and liquid at the same time, and in the working state, the water will flow through the inside of the double concentric hose, and the outside will be encapsulated by the hot exhaust gases extracted from the engine."

"On the one hand, this prevents the water from freezing in the air and clogging the pipes, and on the other hand, it is also possible to control the diameter of the ejected droplets by adjusting the air supply by using the principle of induction."

Lorenzo and Colombo, who were more knowledgeable, glanced at each other.

Again, this is a device that is simple to say, but requires a huge amount of test data to be optimized before it can be put into engineering applications.

It's just like the previous icing simulation software.

It's hard to copy out quickly after getting the physical object.

"It sounds like it can meet the requirements of the experiment, but I wonder if this one nozzle can create a large enough volume of supercooled water to envelop the entire aircraft?"

Lorenzo tried to figure out what he wanted to know in a more tactful way.

Chang Haonan could naturally hear the other party's purpose, but this was originally intended to tell them:

"It is enough, according to calculations, this one jet can form a water mist range of 50 meters × 50 meters in the rear, and if three sets of equipment can be installed on the left and right wings and tail of an aircraft at the same time, then the cross-section can be expanded to 120 meters × 40 meters, even for Airbus...... Uh, the Boeing 747 is enough. ”

He almost blurted out the Airbus A380 before remembering that the name hadn't been decided yet.

Chang Haonan's seemingly casual introduction is actually very targeted.

If Huaxia promised to design the ATR42/72 anti-icing system is to give it fish, and to carry out joint icing and anti-icing research with the European side is to give it fish.

Then this plane is directly contracted for a fish pond.

It allows Airbus and JAA to say goodbye to the Great Lakes of North America and conduct ice test flights of aircraft in Europe.

This is not very attractive to the European Union, which will not be able to hold up the wall in 20 years, but it was different in the 90s.

The EU is a bit like an adult in these years, desperate to prove that it can completely break away from the United States in all fields and at all levels, so it is in dire need of this kind of fishpond contracting.

They will definitely be interested.

After all, the world has been suffering from the FAA for a long time.

That's right, Chang Haonan is ready to sell his own system!

The main thing is that he knows that in about five or six years, Boeing will also use a KC135 to make a similar product.

Then the Frenchman, who also owned the KC135F, quickly caught up.

The main AIT aircraft can be used for decades if one is built, and the water spray system is enough anyway, and there will be no technical iterations.

There is no need to hold it in your hands, and in the end it is cheaper Boeing.

Sure enough, after hearing Chang Haonan's answer, the muscles on the faces of the two twitched slightly, obviously holding back their expressions to prevent themselves from showing too excited expressions.

It's about the same as when Jim Hack hung up halfway through hearing the former prime minister's memoirs.

In short, after finishing today's visit, Lorenzo found Schneider, who had a good time, that night.

"That plane of theirs can allow us to completely solve the problem of the FAA's monopoly in natural icing test flights!"

Perhaps because he was afraid that the persuasion was not enough, he also added:

"The 120-meter×40-meter water mist zone could even be used to complete the tests of our planned A3XX aircraft!"

The A3XX, the predecessor of the future A380.

"Are you saying that we can cooperate with Huaxia for a long time in terms of natural icing test flights?"

Schneider, who was a little tired from a day of visiting, really became interested:

"But what's the difference between this and cooperating with the FAA, the dominance is not in our hands anyway?"

Lorenzo shook his head:

"No, I mean, you can buy one of those planes and go back, and we'll do the test flights ourselves!"
