Leaving Hong Gong behind, Jiang Yan, who was considered by Chief Engineer Lu, was after all the first time to fly south to them, and he was not familiar with this place at all, Hong Gong was a local aborigine, and Jiang Yan's acquaintance, if Jiang Yan had something to do here, it would be more convenient for the two to communicate.

What's more, these two people worked together a lot when they were in Sijiu City, and he was quite clear about Jiang Yan's ability, and he would not look down on Jiang Yan because Jiang Yan was young, and he would play a role in holding him back.

And Director Shen also left his secretary to provide Jiang Yan with some necessary logistics support on his behalf.

When he left, he also explained that his secretary asked him to listen to Jiang Yan's arrangement and take care of everything.

"Old Tang, what is the origin of this Comrade Jiang Yan, this is worthy of the bodyguard arranged by the Security Bureau." Out of the hangar, the director of the factory couldn't wait to ask Dean Tang.

"He! Don't look at his low rank, but he has participated in a lot of projects, if the above didn't deliberately suppress him, it is estimated that he is higher than your position. "Director Shen's secrecy level is relatively high, so Dean Tang didn't hide it from him.

"Did he offend someone?" Director Shen asked a little puzzled.

"What words! It's not that he's offending people, it's his superiors protecting him, and it's not a good thing that he's climbing too high at this age. ”

"This guy is the person who registers on it, and he is the treasure of the first machine department, and it took a lot of effort to come this time." Dean Tang glanced at Director Shen, who was walking beside him, and opened his mouth to explain.

"Oh! It's the fear of killing! I see. I said so! I haven't heard from him. Director Shen touched his head, and then said.

"By the way, arrange the security personnel, I heard that Xi has a spy already eyeing him now." Dean Tang continued.

"Okay, I'll arrange it now. His absolute safety must be guaranteed. After Director Shen finished speaking, he walked quickly to the security room.

After a short while, two armed guards drove to the door of the hangar and began to stand guard.

In the hangar, Jiang Yan and the others went to rest one after another, and they quickly entered the working state.

Jiang Yan casually found a stool and sat there to quickly analyze the flight data and attitude of the wind tunnel test aircraft.

These parameters were cross-compared with the parameters in his mind, and after comparison, Jiang Yan found that it should not be the aerodynamic shape of the aircraft.

In order to verify his judgment, he carefully checked around the two fifth masters several times, and the result was still the same.

Since it's not an external problem, it's an internal component or a piece of equipment.

Nowadays, there can only be one such explanation, and the others do not make sense at all.

"You remove the front and rear landing gears first."

Now that it has been determined, the problem of the internal parts can only be disassembled and measured one by one, and there is no good way.

Therefore, Jiang Yan instructed the workers and masters present to start the dismantling work.

The workers and masters next to him were busy in full swing, and Jiang Yan sat down on the ground between the two planes and began to ponder.

Since it has been roughly confirmed that it is the problem inside, the rest is to completely disassemble the two planes into parts, and then compare them with the parts on the drawings.

can think about it, even if it is the fifth master of this era, there are more than 10,000 parts and components of this plane.

If you wait for the two aircraft to be dismantled, and then compare each part one by one, it will not be compared to the Year of the Monkey!

This is estimated to be a relatively large project, and it is estimated that I will not be able to go back in a short time.

But then Jiang Yan thought that if he did this for ten days and half a month, Chief Engineer Lu and them would have to go crazy!

No, you can't do this needle-in-a-haystack method, you have to play precision strikes.

Thinking of this, Jiang Yan said to Hong Gong on the side: "Hong Gong, can you call the comrades who are testing the flight over?" ”

"Mr. Jiang, wait a minute, I'll call right away." When Hong Gong heard this, he immediately replied.

"It's better to bring in comrades who have flown these two planes." Jiang Yan said again.

Nowadays, if you want to play precision strikes, you need to know roughly where the resonance of the plane is generated, and the best way is to first find the test pilot comrades who have flown these two planes to understand the situation.

After Jiang Yan's order was issued, about half an hour later, a team of test pilots ran quickly towards the hangar where he was.

After receiving the notice, Hula suddenly came, more than a dozen people, these people are all comrades who have flown these two five masters.

A comrade test pilot led by him, after the whole team, saluted Jiang Yan and said, "Report, the first team of flight tests, fifteen test pilots, have been ordered to come to report to you, please instruct." ”

"Don't!" Jiang Yan hurriedly got up and saluted.

For these test pilot comrades, Jiang Yan revered from the bottom of his heart.

The profession of test pilots is a profession full of great challenges and dangers, especially in the current era, the environment and protection of China's aircraft test flights are not perfect enough, it can be said that every time they fly an aircraft into the air, it is accompanied by huge risks and uncertainties.

It is possible that this launch will be their last......

"Comrades, can anyone tell me first, where did the vibration you feel come from? Jiang Yan pointed to the problematic fifth master and said.

"The vibration came from the right side of the fuselage, and this vibration was most intense during the rapid climb of the fighter, and if we maintained a stable flight attitude, this vibration could almost be said to be none, and we did not feel this kind of vibration when we were making a rapid descent and dive."

Jiang Yan asked several test pilots one after another, including two comrades who had flown these two five masters at the same time.

The conclusions drawn are all about the same meaning.

Now this general direction is there, but the difference from the original does not seem to be big.

On the right side of this fuselage, the nose, fuselage, wings, and tail are still too large.

This will have to continue to narrow the space for suspicion.

Jiang Yan continued to chat with these test pilots, in addition to this shock, their evaluation and feelings of the fifth master.

As soon as they talked about this, these test pilots immediately talked to Jiang Yan with their eyebrows.

To sum up, except for the resonance phenomenon of the second fifth master when climbing at high speed, they simply love the new fifth master.

They unanimously agreed that the new Wuye is an aircraft with advanced technology, simple structure, lightweight, flexible, fast climbing speed, good high-speed performance, and can carry out medium-low altitude and ultra-low-altitude operations, especially one suitable for low-altitude and ultra-low-altitude high-speed penetration operations, and they are the ideal aircraft.

Hearing their evaluation of this aircraft, Jiang Yan was very satisfied, what these test pilots didn't know was that when this aircraft was developed, Jiang Yan and Lu Zonggong had a large number of aircraft, and it was not completely a OnePlus fighter, but as a new aircraft platform.
