Aero engine is the crown of industry, and in this world, there are only a handful of countries that can develop aero engines on their own.

The domestic aero engine industry, for a long time, has been an imitation of the road, the introduction of the MiG-17, also the introduction of its engine, named turbojet-5, the introduction of the MiG-19, the introduction of the turbojet-6, the introduction of the MiG-21, the introduction of the turbojet-7.

And then?

Then it was interrupted, and the introduction could not be introduced, and the domestic aero engine was cut off.

In order to aim at the advanced level of the West, China has also begun to launch the turbofan engine project with great interest, which is the turbofan-6.

When the J-9 project was established, an advanced turbofan engine was needed, so to speak, the turbofan-6 was developed for the J-9, and later, the country wanted to build the Qiang-6, which is a variable sweep wing attack aircraft, and also wanted to use the turbofan-6 to equip.

In this way, the turbofan-6 engine was established in the sixties, and within two years after the project was established, it was quickly put on the test bench, and then began a long test run.

This test run has been tried until now.

Qin Feng understands the turbofan-6, that's all, and now, while everyone is walking towards Factory 410, Wang Yang introduced to Qin Feng: "Our left is Factory 410, and on the right is Factory 111, this Factory 111 is even more famous." It's been sixty years. ”

Hearing Wang Yang say this, Qin Feng reacted: "Brother Yang, you say so, isn't that the factory that was taken from Zhang Zuolin?" ”

"That's right, yes!" Behind Wang Yang, a companion said: "Our 111 factory, that is famous in the country, everyone is proud of coming from the 111 factory, it can be said that all the big factories in the country can see our 111 factory." ”

"Even if it is Factory 410, in the mouths of our people, it is called the West Courtyard, and the 111 Factory is called the East Courtyard."

Everyone walked and chatted at the same time, and Qin Feng understood the origin.

The 111 factory, originally from the 111 factory of the Aviation Department of the three eastern provinces established by Zhang Zuolin in 1920, is also the old aviation industry base of New China.

As the first jet aircraft engine factory in China, the 111 factory, which was established in 1951, undertook the important task of repairing the aero engines of the War to Resist US Aggression and Aid Korea.

At that time, the 111 factory was the most dazzling unit in the country, and a workshop director would be a department-level cadre from other provinces, a deputy director of security, and the director of the public security bureau transferred from other places.

Scientific and technological personnel and front-line workers from all over the country poured into the 111 factory, and as soon as they walked into the factory with the accents of Lianghu, Liangguang, Sichuan, Jiangsu and Zhejiang, they were shocked by a slogan: "The workshop is the battlefield and the front line"!

That's right, at that time, the 111 factory was the most important unit, out of the War to Resist US Aggression and Aid Korea and the need for military secrecy, even if they wrote a letter to their family, they could not write anything secret, and there was no address on the letter sent back to their hometown, only a mysterious "419 mailbox".

The War to Resist US Aggression and Aid Korea chased everyone, and if you don't know how to do it, you will learn to do it. Self-reliance, never admit defeat, after the founding of the People's Republic of China, all parts of the country are such high-spirited momentum, and the 111 factory is even more so.

At the same time, as the first aviation industry plant, the 111 factory not only undertook the most important task of repair and manufacturing, but also undertook the important task of aiding the construction of brother units.

In 1954, Shenyang Aviation 410 Factory was established, and the then 111 Factory took out half of its wealth and sent 60% of its personnel and equipment to the new factory.

Four years later, Chengdu Airlines 420 Factory was established, and 60% of the people and belongings were allocated in the factory.

Shaanxi Xi'an 113 Factory, 430 Factory, Jilin 531 Factory, Sichuan Daxian 064 Base 7304 Factory, Hubei Yuan'an 066 Base Jiangbei Machinery Factory, Shaanxi Lantian 067 Base 7414 Factory, Guangxi Liuzhou 801 Factory, Inner Mongolia Hohhot 359 Factory, Guizhou Zunyi 061 Base 3532 Factory...

Over the years, Factory 111 has successively contracted and assisted the construction of 11 large and medium-sized military factories, supporting 15,000 personnel and more than 1,000 sets of equipment. In the annals of the Republic's national defense construction, the 111 plant has made immortal contributions and is known as "the cradle of aerospace power plants and one of the birthplaces of the traditional spirit of aerospace".

When he heard this, Qin Feng was in awe, at this time, he had already walked to the door of Factory 410, but he still couldn't help but stand up and salute Factory 111.

It can be said that the 111 factory is the root, flowering and scattering, all over the country, without the 111 factory, there is no current aviation industry of the motherland!

"Hey, what are you doing here? Come to our west courtyard and salute the east courtyard. At this moment, a security chief who was guarding the door came out and said.

"Section Chief Zhang, we came here from 601, it's freezing this day, it's very cold to see the ice lamp, come in and bake the fire."

Wang Yang knew him, and as soon as he said this, Section Chief Zhang looked at everyone: "Well, let's go in." ”

Wang Yang is also a little famous here, after all, when the J-8 was just built, he was the first to fly the J-8, and he is also an old frequent visitor here.

Qin Feng was overjoyed in his heart and followed inside.

After a few turns, a rumbling roar was heard ahead.

"It's so late, why is there still the sound of this engine?" Qin Feng was very strange, then listened to it again, and said: "It's not the same as the sound of our turbojet-7, it can't be the turbofan-6, right?" ”

Now, what can be produced in China is the turbojet-7, other engines are too old, and the J-7 and J-8 that have flown so much can be recognized by Qin Feng at once.

It's not the turbojet-7, it's the turbofan-6?

"Go, follow me." Wang Yang said, and led everyone into a workshop.

The workshop is very empty, and you can see that in the center is a test bench, and at this time, there is an engine roaring on it.

The engine was stout, two orders of magnitude thicker than the previous Turbojet-7, and its exterior was pitch black, and the accessories and pipes could not be seen, perhaps due to dim lighting, or oil stains on the outside.

At this time, the nozzle at the tail can not see the flame, can only see the black smoke is constantly coming out, the top of the entire test bench, there are so many large fans, is now whirring outward, if not, the whole workshop must be filled with black smoke, just like the fire.

This, what's going on?

Qin Feng looked at this scene and couldn't help but stop, this should be starting the engine, right? But look at the appearance of the black smoke, and the voice I just heard, at least a minute, and it hasn't started successfully?

"Stop, five minutes later, try to start again!" Just then, a voice spoke.

With the voice, Qin Feng looked over, it was a middle-aged man, he was not tall, wearing an oily overalls, and his face was full of anxiety.

At this point, the engine stopped, and he turned his head to look at the uninvited guests.

"Mr. Zhang, are you still busy?" Wang Yang said.
