The sky outside has been dark, in the hazy night, there are many people walking by the river, Qin Feng and Gu Tingting are walking, listening to her analysis, it turns out that there is this relationship in the middle, it seems that the 132 factory is now walking a tightrope, but no matter how difficult the road is, how much resistance, you must go on bravely, because all this is for the motherland.

The country's aviation technology is too backward, and this is the most effective and fastest plan to improve the combat effectiveness of the air force's fighters.

Qin Feng's future and destiny have also been closely linked to Factory 132.

The next day, Qin Feng took a few companions from the 611 Institute and stepped into the gate of Factory 132, and as soon as he entered the gate, he saw the doorman and said: "Comrade Qin Feng, you are back, great, Tu Lao is looking for you." ”

Tu Lao looking for himself?

Qin Feng asked his companions and Gu Tingting to go to the shooting range for testing the aircraft artillery first, and strode towards Tu Lao's office by himself.

In Tu Lao's office, there was a thin middle-aged man standing at this time, although this middle-aged man was thin, his spirit was quite good.

When Qin Feng pushed the door open, the other party also happened to turn his head, turned his head to look at Qin Feng, looked at each other, and saw that familiar look.

Pilot, only an experienced pilot can reveal such a gaze in his eyes, Qin Feng can confirm it at once.

"Qin Feng, let me introduce you, this is Comrade Sun Tianqin, he is an experienced pilot, he has been flying for more than 1,000 hours, after Wang Gang left, our factory still needs test pilots, especially for projects with the United Kingdom, we also need more test pilots, so ah, after the coordination of the superiors, Comrade Sun, will become the resident pilot of our factory in the future." Tu Lao said.

Comrade Wang Gang has already left, and in the factory, there is still a need for test pilots, especially the project with Marconi Company, and various test flights have begun to be planned.

So, here comes another one.

"Hello, I'm Qin Feng, please give me more advice in the future." Qin Feng said.

Although Qin Feng is now one of the most famous test pilots of Factory 132 and even the entire Air Force, Qin Feng's flight is less than 500 hours, more than 1,000 hours, and he is definitely the elite among pilots.

"I can't talk about advice, in the future, let's cooperate more, Comrade Qin Feng, your name, the whole army knows it." Comrade Sun said: "I am older than you, in the future, you will call me Lao Sun." ”

Comrade Sun in front of him looks like he is in his forties, right? Qin Feng stretched out his hand and clasped his hand tightly: "That's not good, you are twenty years older than me to say the least, where can I call you that, I still call you Brother Sun." ”

In the army, it is not advisable to call brothers and sisters, it is easy to make mistakes, but this is a factory, everyone is spontaneously close, just like a family, Wang Gang and Qin Feng have been calling Brother Gang in the past, and Brother Sun in front of him looks older than Brother Gang.

"I'll call you Xiao Qin, in the future, we can work together, by the way, this weekend, don't you have a break?"

"I brought in a few assistants to test the ballistics of our guns." Qin Feng said, since Tu Lao is here, then simply say hello to Tu Lao.

Thinking about what Gu Tingting said to herself, Qin Feng still didn't say it, this reason, saying it can only make Tu Lao's heart even more panicked, it's better not to say it.

Do what you should do, and that's enough.

"Let's go, let's go together, this cannon, I'm also familiar with it, in the past, in the factory, I did the maintenance of the gun." Brother Sun said.

At the factory, repair of aircraft guns? When Qin Feng heard this, he immediately became strange: "You are still entering the aircraft artillery factory?" ”

Pilots, almost all of them are in the army, a small number of elite pilots, come to the factory to test the flight of fighters, such pilots, in the factory, that is the most respected, it can be said that the factory needs good food and drink to support, pilots will not participate in the production of the factory, as long as the flight is good.

In particular, it is absolutely impossible to give repair of aircraft guns.

"yes." While the two walked out, Brother Sun said to Qin Feng: "A few years ago, I was grounded, first went to the Wuqi Cadre School, labor reform, and later, I went to the 22nd factory of the Air Force, where I began to repair aviation artillery. ”

"Why?" Qin Feng was even more strange.

"The ingredients are not good." Brother Sun said and smiled open-mindedly, and Qin Feng's heart suddenly chuckled.

That's right, in that turbulent era, once the ingredients are not good, they may be investigated in the flying career at any time, grounded or something.

It seems that Brother Sun was also hurt in that era.

"Brother Sun, with you coming to our factory, we will be more confident, you are Lao Fei, we will have more problems in the future." Qin Feng hurriedly changed the topic.

While talking, the two finally came to the special test range in the factory.

If you just look at the plane, it seems that the aircraft cannon is just a small cannon muzzle, but in fact, what is exposed is only a drop in the ocean, and there are more hidden in the plane.

This 30 mm cannon has been fixed to the bench at this time, which is a big guy more than two meters long.

The whole cannon is composed of 6 kinds of parts and 163 kinds of parts, including the barrel, the ammunition feeding machine, the air-conditioning reloading mechanism, the gun box, the machine core, the electric ignition machine and the final assembly parts, with simple structure and convenient assembly and disassembly.

On the fighter, it is all hidden under the belly of the J-7, equipped with two doors, launched out, it is a powerful combat weapon, at this time, you can see the yellow-orange-orange bullet chain outside, 30 mm training bullets, has been stuffed in.

If it is really used on a fighter, it is an anti-personnel explosive incendiary bomb, and now, although it is a warhead that cannot explode, it looks like it is also very powerful, if it hits a cow, it can also blow the cow up, and if you dive into the tank from the sky, you can burst the top cover of the tank.

"This cannon is the most powerful cannon in our country." After just a glance, Brother Sun clearly said its origin: "Although it is powerful, because of the large caliber, when the cannon is ejected from the muzzle, the muzzle velocity is only 780 meters per second, and the trajectory is curved, if there is not enough technology, it is difficult to hit the target." ”

The higher the muzzle velocity of the warhead, the flatter the trajectory, and the smaller the muzzle velocity, the more curved the trajectory of the projectile will be while in flight.

This cannon, although the caliber is large, but the aiming is definitely a technical job.

The layman looks at the excitement, the insider looks at the doorway, Brother Sun said this, Qin Feng couldn't help but give a thumbs up, he continued: "Also, this kind of cannon is a tube-retreated, sliding machine-core single-barreled cannon, with a large recoil, coupled with the use of gas barrel structure, it is difficult to maintain after shooting, in fact, it is better to use our 23mm gun." ”

These shortcomings are too right, and because of this, the J-8 went back and used a 23mm gun.

However, now with Marconi's avionics and aiming with the cannon hotline, this big problem can be easily solved, and it will all be left to the electronic system!
