The military-industrial scientific research system of the academic master

Just when Chang Haonan turned around, a buzzing sound suddenly came from a distance.

It's not the high-frequency whistling sound of a turbofan engine.

He subconsciously turned around and saw a small black dot slowly descending from the horizon.

In addition to the flight test institute, Yanliang Airport is used for 603. Except for the Y-7 they took when they came here, there are very few "normal" models appearing here.

Curiosity made him stop and watch.

The plane's approach speed was not slow, and Chang Haonan's eyesight was not bad when he was young, so it didn't take long for him to see the twin-propeller plane.

At first glance, the appearance is not much different from the Y7 they took that day, but it is not painted, so it is obviously not a mass-produced aircraft.

Because of the setting sun, Chang Haonan raised his hand to block the dazzling light and squinted his eyes slightly.

Then he saw that the plane was equipped with a pair of wings that he was very familiar with.

He said he was familiar with it, but he had actually never seen it with his own eyes before. Even on the design drawings, he had only seen it for a day.

But to a certain extent, it was that day that gave him the opportunity to participate in the August 3rd Project.

Although the wing design itself was not his work.

Yes, this should be a MA60.

but……

"Why is there a MA60 without paint?"

Chang Haonan smoothed his hair, his legs began to move almost involuntarily, and he walked towards the test flight site over there.

According to his memory, during the entire airworthiness test flight process, there was only one demonstration aircraft of the MA-60 in flying condition, and that aircraft was painted with a very distinctive painting.

When the plane's wheels touched the ground and made a "squeak" sound, Chang Haonan also crossed a bush and saw the situation inside the airport.

A group of people were standing on the tarmac.

As the plane slowed down the runway and onto the taxiway, he heard cheers erupt from the crowd.

The posture looks similar to when the No. 04 prototype of the J-8-3 made its first successful flight a few days ago, but the scale is much smaller.

After all, the weight of Xinzhou 60 is far inferior to that of Project 83.

Relying on the certificate he carried, Chang Haonan successfully entered the test flight area.

There are no big names here, so there are only normal confidentiality requirements and no additional security requirements.

Chang Haonan's current confidentiality level is high enough.

He lingered around the tarmac for a while, watching the plane taxi to the tarmac before the test pilot received a hero's welcome.

Originally, as an outsider, he should have left after watching here for a while.

But after the welcome ceremony was over, a very familiar figure to Chang Haonan appeared among the crowd dispersing.

"Chang Haonan?"

"Uh...Professor Liu?" Chang Haonan touched his nose and looked at the person in front of him who was also walking towards him with a surprised look on his face: "What a coincidence, you are here too?"

The visitor was naturally Liu Hongbo.

"They are all students of Mr. Du, just call me senior brother."

Liu Hongbo waved his hand:

"You should know that our team is responsible for the design of this model's engine nacelle, so I was also called here for the first flight ceremony."

At the beginning, Chang Haonan actually wanted to say that he didn't know, but his focus was quickly shifted to the keywords in the second half of the sentence.

"Okay, Senior Brother Liu, but did you just say first flight?"

Theoretically, the first takeoff of every aircraft after leaving the factory can be regarded as its first flight, but Chang Haonan knew that the other party probably did not mean this.

Just when Liu Hongbo was about to open his mouth to explain, a tall and thin old man walked behind him.

"Hong Bo, this is..."

Chang Haonan's work permit is still hanging on his chest, but the font on it is not obvious.

"General Engineer Yi, this is Chang Haonan, a student of Academician Du."

Within the aviation system, Yi Yuanhe's name is not as well-known as Song Wenchong, Yang Wei, Sun Cong or Luo Yang. In fact, Chang Haonan had not paid attention to who the chief engineer of the MA60 was before his rebirth, so he spent about It took half a second to search the other party's name from memory.

That was the day he completed the wing flutter analysis. Du Yishan said he was going to find one of the two people in Haojing.

But before Chang Haonan was about to speak, Liu Hongbo turned around and introduced:

"This is Yi Yuan and Chief Engineer Yi, the person in charge of the Xinzhou 60 project."

Interestingly, although Chang Haonan helped the entire project team solve one of the biggest issues, and although Yi Yuanhe declared Chang Haonan as the first completer of advanced technological achievements, the two had never met before.

"Hello, Mr. Yi."

"Comrade Chang Haonan."

Yi Yuanhe came up and held Chang Haonan's hand.

He really didn't expect that the other party would be so young.

Therefore, after a long silence, he spoke again: "Although this is the first time we have met, you should be considered as the most important contributor to the fact that the MA60 project has come to this day."

The first sentence made Chang Haonan feel a little embarrassed.

"You are too complimentary. You just made some small contribution."

He is not a person who is shy about admitting his credit. The reason why the MA-60 can be equipped with this more advanced new wing is indeed because of his precise calculations and a set of active control laws that can greatly increase the flutter speed.

But compared to the entire project, he really can't say that he takes the most credit.

There is still a big gap between giving a control rate and designing a flight control system.

Perhaps he can be worthy of this kind of evaluation in the August 3rd Project or some other subsequent projects.

Looking at the young face in front of him, Yi Yuanhe smiled slightly:

"Young people don't need to be so modest. Although you didn't design anything for this aircraft, your precise calculations made the entire project viable."

As he spoke, he looked back at the plane that had just stopped for a short time. After the pilot left, a group of engineers began to go up and record flight data.

Even if the actual first flight does not have many subjects, even a little more flight data is valuable.

"Well?"

"The MA-60 is the first aircraft in the world to use fused winglets. Compared with traditional single-piece winglets, it is more effective and more difficult to design." Yi Yuanhe said with a hint of tone. With a little pride:

"Our engineers completed the design independently, but if it weren't for you, it would never have been installed on the aircraft."

"So, you built a new verification aircraft?"

"No, that verification aircraft had been put on new wings for test flight more than a month ago." Yi Yuanhe shook his head: "This is the No. 01 prototype of the MA-60."

The verification machine and the prototype machine may sound similar, but they have completely different tasks.

Some projects are even subdivided into technical demonstrator, engineering demonstrator and prototype machine.

If we compare it to the automobile industry, the demonstrator is equivalent to a concept car and the prototype is equivalent to a prototype car.

"Because of the demonstration aircraft after the wing was replaced, we directly received an investment and an order for eight aircraft from Beijiang Airlines, as well as an intention to cooperate from the Italian company AgustaWestland."

Brothers, I’m really tired of it. I’ll take a day off after two chapters. I’ll update the new helmsman tomorrow.
