The lieutenant colonel stood outside the office door, with a look of reverence on his face, and tapped lightly on the door a few times.

The door to the office was unlocked, but it was hidden, revealing a crack with the Lieutenant Colonel's snap, and the lights in the office spilled through the crack.

There was no one inside to respond, and the lieutenant colonel looked puzzled and continued to knock a few more times.

"Secretary Lu, Chief Engineer Yan is not in the office and has gone to the workshop."

The door of the next office opened, and a middle-aged man in a white lab coat came out with a document in his hand, and as he spoke, he reflexively closed the office door.

Although the man was wearing a white coat that covered the rank on his shoulders, it could still be seen from the collar badge that he was a colonel.

"Good week." The lieutenant colonel saluted and said hello, and then asked, "What workshop is the chief engineer in?" ”

"Hello chief." Seeing his collar badge, Yang Luo raised his hand and stood up in salute.

"Workshop 3, I just heard the voice of the director of workshop 3 and Chief Engineer Yan leaving together."

The middle-aged man who was called Zhou Gong by the lieutenant colonel replied to the lieutenant colonel's question, and then looked at Yang Luo and said, "This is the person invited by Chief Engineer Yan to test the KD-120?" ”

The lieutenant colonel replied, "Yes, Zhou Gong." ”

"Yes, the young man is in good spirits." Zhou Gong said with a smile, turned around and hurried away.

When Zhou Gong walked away, Yang Luo asked curiously, "Who is this chief?" ”

Compared with Yang Luo, a small captain, the colonel is the absolute chief, regardless of the other party's rank of the main regiment or the deputy division.

"He's Zhou Gong, a senior engineer at the base, who mainly studies air-to-ship missiles." The lieutenant colonel said with a smile as he gently pushed open the office door.

From the words of the lieutenant colonel, Yang Luo knew that this Zhou Gong was a technical cadre and did not have an administrative position.

Engineer is only a technical title, not a job title.

This phenomenon is very common in the troops, especially in such technology-oriented units, where there are usually many high-ranking and high-ranking officers and cadres in the establishment.

At Dongling Station, Yang Luo had met a technical cadre at the level of a major correction division, a radar staff officer, but he was under the command of the radar station commander of the major correction battalion, and the administrative level of the radar station was at the battalion level.

This is the difference between a purely technical cadre and a cadre with an administrative post; no matter how high the rank and rank of a technical cadre is, he or she must obey the management of the unit commander, even if the rank and rank of the chief officer are lower than his own.

"Squeak!"

The office door opened with a small soft sound.

"Comrade Yang Luo, come in first, sit here for a while."

The lieutenant colonel walked into the office, led Yang Luo to the coffee table of the reception, and made a gesture of please.

Yang Luo sat down.

The lieutenant colonel took out the tea leaves, made a cup of tea, put it in front of Yang Luo, and said, "Comrade Yang Luo, you wait here first, and I will go and ask Chief Engineer Yan." ”

"Thank you." Yang Luo thanked him.

After the lieutenant colonel left, Yang Luo looked at the layout of the office.

It's a very simple office, with a desk, a coffee table and sofa for guests, and other cabinets against the wall.

On the cabinet are not books, but various folders, as well as models of missiles.

Thunderbolt-12, YJ-91, KD-88, C-803......

Yang Luo has seen and has not seen the airborne launched missiles, there are models here, and there are even foreign missile models, such as KH-59, AIM-120......

It's like Grandma Liu entered the Grand View Garden, which can be regarded as a big opening for Yang Luo's eyes.

Yang Luo is now standing in front of a model of a missile with PL-25 written on it.

The Thunderbolt series of missiles is an air-to-air missile used by the Chinese Air Force, which has developed from the earliest Thunderbolt-1 to the Thunderbolt-21, with close-range combat models, medium-range and long-range interception models.

Other types of Thunderbolt missiles, even if some Yang Luo has never seen them, have heard of them, such as the earliest Thunderbolt-1 and the latest Thunderbolt-21, which have been eliminated.

But the missile in front of him, named PL-25, Yang Luo not only had never seen it, but he had never even heard of it.

Because it is a scaled model, it is impossible to specifically judge its parameters, let alone its performance, and Yang Luo is just looking at the appearance.

"This is our latest ultra-long-range air-to-air interception missile, with a range of up to 500 kilometers, and it is still being tested."

Suddenly, a voice came into Yang Luo's ears from behind.

Yang Luo looked back, but an old man over the age of sixteen walked behind him, also wearing a white coat and holding a folder in his hand.

The forehead of a Chinese character face is wrinkled, the hair has turned a lot gray, and a pair of black-framed glasses are framed on the bridge of the nose, which is quite bookish.

Through the colorless lenses, you can see a pair of small black eyes, which are small but not cloudy, but bright and bright.

His eyes swept over the collar badge, Yang Luo's eyes shrank slightly, this was a general with the rank of major general.

"Hello, chief." Yang Luoli stood up and saluted.

Without thinking too much, Yang Luo also knew that this was Chief Engineer Yan.

Judging by the fact that the other party is wearing a white coat, it is obvious that he is a technical cadre (the highest rank of major general, technical level 1).

Also known as Chief Engineer Yan, that must be the Chief Engineer, this is a senior technical cadre with a position.

Chief Engineer, also known as Chief Engineer, is not a technical title, but a position.

The chief engineer is an administrative position in the organization of the operation of the product project system, and a professional and technical position in the organization of the operation of the functional department system.

"You're welcome, I don't need these courtesy things here." Chief Engineer Yan replied with a kind smile and a standard military salute, and said, "There was something just now, so I made you wait for a long time, sit down and say." ”

"Today's game is over, I have time, but your time is more precious, I should wait." Yang Luo said with a smile, looking at Chief Engineer Yan's eyes full of respect.

Esteemed!

Yes, for the old man in front of him, who has shown an old state and silently dedicated his whole life underground, there is nothing but respect from the heart.

In Huaxia, it is precisely because there are too many such selfless people that they have become strong step by step and have a pivotal position in the world today.

"Originally, I should have gone up to you in person, after all, I wanted to ask you for help and seemed more sincere, but something happened to happen in the workshop today, so I had to invite you down to see me, an old man." Chief Engineer Yan said with a smile.

Yang Luo hurriedly said: "Chief, you are a terrible boy, I should have come to see you, how can I let the chief run away in person." ”

"Alright, let's not talk about that." Chief Engineer Yan waved his hand, "Do you know that I came to you this time to help me?" ”

Yang Luo shook his head and said, "I guess it should be related to missiles, but I don't know what it does." ”

"I'm looking for someone to help me test launch a missile, Commander Wang recommended you to me this morning, and I've also seen the video of your game, which basically meets our requirements, are you willing?" Chief Engineer Yan said, a pair of bright eyes, staring at Yang Luo's young and slightly immature face.

"Test missile?"

Yang Luo was surprised.

This Wang commander Yang Luo knew that he was the highest military commander of the Dingxin base.

However, this test missile is a bit strange.

One of the tasks undertaken by the Dingxin station is to be responsible for the test and target tasks of air-to-air and air-to-ground missiles and new weapons and equipment of the Air Force.

And now he has to find someone from the outside, which has to make Yang Luo surprised and puzzled.

"You heard it right, it's a test missile." Chief Engineer Yan said solemnly, "Comrade Yang Luo, explain in advance that this is an extremely dangerous task, are you willing?" ”

"Yes!"

Yang Luo didn't hesitate and agreed straightforwardly.

Dangerous?

What about the dangers?

Soldiers, not afraid of danger.

"This test launch is our newly developed ground-penetrating armor-piercing missile, whose explosive yield can theoretically penetrate at least 15 meters of reinforced concrete fortifications, but because of the limitation of the fuel tank, its front-end speed is affected, so I need you to use an aircraft to accelerate it." Chief Engineer Yan said in a deep voice.

"How much? How fast do you want to? Yang Luo asked, he had a bad premonition, this speed must be very large.

"At least Mach 2.2, preferably Mach 2.5." Chief Engineer Yan looked at Yang Luo and said slowly, "I know that the J-10C can't reach a speed of Mach 2.5, so the speed of Mach 2.2 is almost enough." ”

Yang Luo said: "I can fly up to Mach 2.35. ”

"Really?" "If you can really fly to Mach 2.35, that's great, and the chances of success are greatly increased." ”

Yang Luo frowned and said: "It stands to reason that although the speed of Mach 2.2 is almost to the limit, many models can reach it, how can it ......?"

"If only it were that simple." Chief Engineer Yan smiled bitterly, "Not only does it have requirements for speed, but also for angles, and it is necessary to dive at an angle of no less than 60 degrees,"

Not level flight, but dive?

Also to dive at an angle greater than or equal to 60 degrees?

And to accelerate the missile to at least Mach 2.2?

Yang Luo's eyes widened.

This is a missile designed by that genius, and it is so demanding that a few pilots dare to do it.

Theoretically, this can be done.

At the ceiling height, the afterburner is turned on and the gauge speed is dive at a large angle, and the speed can reach or even exceed Mach 2.5 when approaching the ground.

But the problem is that there is not much altitude and time left for the pilots to change out.

Let's not forget that a fighter cannot maneuver until it exits hypersound.

In other words, the speed of the fighter must be slowed down from 2 times the multisonic speed to subsonic speed before maneuvering.

This requires not only flight skills, courage and guts, but also the physical fitness of the pilot, because it is necessary to maneuver at a large angle, from a large angle dive to a large angle climb, and the angle in between must definitely exceed 270 degrees, otherwise it will not be able to resist inertia in the vertical direction.

And the instantaneous overload generated by this large-angle maneuver is at least 10 G, or even more possible.

Dangerous.

Very dangerous.

"Hey, if you don't want to, forget it, I don't force you, I'm looking for someone else." Looking at Yang Luo's expression, Chief Engineer Yan sighed and said disappointedly.

"No, chief, I don't regret it." Yang Luo hurriedly said.

Even though this task was indeed very dangerous, it aroused Yang Luo's interest, and his eyes flashed with a light called excitement.

In normal flight training, no one dares to fly like this, and no one dares to do so, regardless of how dangerous it is, and it will not be possible to pass the hurdle of flying safely.

It is only this special task that allows the regulations to fly safely for the time being.

Such a flight mission, unheard of, is full of challenges and excitement.

Compared with the test flight mission that I was invited to participate in at the end of last year, this time it was even more exciting.

And Yang Luo just likes excitement.

Of course, Yang Luo is not a fool, he is not sure, he will not agree, and he will not joke with his life.

In fact, Yang Luo had just simulated it in the system space once, and it was successful.

"What did you say?" This time, it was Chief Engineer Yan's turn to widen his small eyes, and he asked in disbelief.

He was ready to find someone again, even though he knew it would be difficult to find.

Yang Luo said solemnly: "I said I was willing." ”

"Do you really want to?" Chief Engineer Yan spoke solemnly and said seriously, "You have to think clearly, it's really dangerous." ”

"I do." Yang Luo also responded with a serious face.

"Good, good, good!"

Chief Engineer Yan happily said three "good" words in a row, grabbed Yang Luo and said, and sincerely thanked him, "Thank you, Comrade Yang Luo." ”

This move made Yang Luo at a loss, not only how to be good.

"When your competition is over, our mission will begin," Yan said, "and you can compete with peace of mind in the next few days and strive to win a golden helmet." ”

"Yes." Yang Luo said loudly.

Chief Engineer Yan then said: "Oh, by the way, this mission is top secret and must not be mentioned to anyone." ”

"Understood." Yang Luo nodded in understanding, and finally asked, "Chief, I want to ask, have you test-fired before?" ”

This is the question that Yang Luo has always wanted to ask, he doesn't believe that Chief Engineer Yan will be reluctant to go far from the beginning and let the pilot of Dingxin Field Station not use, but to find someone to participate in the competition.

"I tried, but it failed, the missile didn't go out, and the pilot didn't dare to continue accelerating before it had accelerated to Mach 2 speed, and finally he gave up." Chief Engineer Yan's voice was a little low, "I don't blame him, after all, not everyone dares to take this risk." ”

"I see."

Yang Luo knew that few people dared to do this kind of thing.

Imagine what it is like to dive at a speed of more than Mach 2, reducing the altitude of more than 600 meters in one second, which is many times faster than a free fall.

Even if the acceleration time is added, it will not take more than 1 minute from the ceiling height to the ground.

"Okay, I'm done with business, and I'm delaying your dinner." Chief Engineer Yan immediately said with a smile on his face, "In this way, stay here to eat and taste our food." ”

"That kid has no choice but to be respectful rather than obey." Yang Luo also replied with a smile.

"Okay, let's go, it's time for dinner in the cafeteria." Chief Engineer Yan smiled, took off the white coat on his body, hung the hook on the wall, checked the documents, and turned to open the office door.

Yang Luo followed the footsteps of Chief Engineer Yan and went to the canteen of this underground base together.
