Chapter 622

No wonder the chief of the air force is like this, because according to the scale of the wd-30s turbofan engine produced by Tengfei aviation power, the annual production capacity of 100 units is already a very powerful number.

After all, the plant area around the whole assembly line 0 is only over 50000 square meters, and there are several supporting processing workshops, which further reduces the area left for the assembly workshop.

The assembly of aero-engine, especially the turbofan engine, is a high-end production process combining fine adjustment and complex process. It is difficult to get up quickly in many places, or even the assembly will leave a great potential safety hazard.

Because of this, in the world, engine assembly is a slow work, no matter the size of the average assembly time of an engine is more than a month.

Among them, the assembly efficiency of leap series turbofan engine produced by CEF international, a joint venture between GM of the United States and SNECMA of France, is the fastest, but it still takes 35 days to complete the assembly process of a leap turbofan engine.

Pratt & Whitney in the United States is a little worse. It usually takes 45 to 50 days to assemble a turbofan engine. Rowe in the United Kingdom is similar to Pratt & Whitney. In other countries, it's fast to assemble a turbofan engine in 50 days.

Among other things, the average assembly time of the Spey turbofan engine used by northwest aviation development plant for a fighter bomber is 62 days. In other words, even if all the parts are put there and installed the same way, it will take two months to complete a usable aero-engine.

If you add in more than half a month's factory performance test, you can imagine how much capacity this year will have. It's not too poor to describe it.

The wd-30s turbofan engine produced by Tengfei group is not as large as the above-mentioned large and medium-sized turbofan engine in volume, but it is only limited to the size of the special fixture and fixed station for assembly, but it is similar in process, that is to say, there is no difference in the general assembly procedure of large Aviation turbofan engine in wd-30s turbofan engine.

Under such circumstances, how does Tengfei aero power achieve an annual output of 400 wd-30s turbofan engines?

You should know that according to the area of No. 0 assembly workshop, it can provide up to 20 assembly stations, and according to the fastest way to assemble one engine every month, the production capacity of a month is only 20, and that of a year is only 240. The problem is that this is the most ideal theoretical situation. Even the world's top CEF international company can not reach the speed of assembling one engine in 30 days Will it be more powerful than the world's top air development company?

Is it self boasting or daydreaming when you have some achievements?

Based on this, after the exclamation of surprise, the air force chief who inquired immediately calmed down and looked at Liu Chun strangely. It was like looking at a very ordinary but boastful old comrade. Although he did not refute, he was full of tolerance from the inside out.

Not only the head of the air force, but also the leaders and heads who know a little bit about the aviation industry have such a mentality. After all, the head of the headquarters is there, and Tengfei aviation power has been brilliant enough during the workshop inspection just now.

At this time, a little boasting, shouting slogans, and striving for more funds and funds from the superior departments are too normal routine operations.

Compared with other enterprises that can blow the capacity to the sky, take off aviation power is conscience.

"When did you become so reserved?"

Other leaders and leaders think like this, and the head of the headquarters is not free from vulgarity, but he has some understanding of Zhuang Jianye, so he asked with a smile.

When Zhuang Jianye heard this, he was really full of black lines. Didn't they pull their figure below the altitude line when they went to the capital for funds? Is it difficult to fight with the major departments in the capital every time?

Therefore, Zhuang Jianye hastened to explain: "chief, your words frighten me. Our group is always conscientious and law-abiding. On the issue of funds, we apply legally in accordance with the requirements of our superiors."

"At the beginning of that year, who blocked me for more than half a month outside the headquarters like a dogskin plaster, and I didn't give up until I went for 100 million?" The head of the headquarters glanced at Zhuang Jianye and asked without expression.

Zhuang Jianye was stunned for a moment, as if he knew it for the first time. He exclaimed: "is there such a bad thing? Why don't I know? Chief, rumor making is absolutely rumor making. How can a key enterprise leader under a ministry do such a bad thing?

Chief, if you have any photos or videos in your hand, please give them to me. I'll go straight to the court and sue him. I've lived for more than 30 years, and I've never seen such a brazen person. "

His words were loud and impassioned, and he almost died with the enemy with his explosive bag. However, these remarks made several people around the head of the headquarters numb. They have seen shameless people, but they have never seen such shameless people. It's clear that you Zhuang Jianye didn't admit it. Do you want that forced face?

However, surprise comes from surprise, but there is no way to retort, because Zhuang Jianye made it very clear that there are photos or videos, and he didn't identify anything?Nima ~ ~ finally saw what is shameless.

The head of the headquarters was not surprised. After listening to Zhuang Jianye's words, he just gave a smile, then looked around and frowned: "it seems that this is not the way to return?"

Zhuang Jianye smile: "yes."

At the end of the speech, a flash appeared in front of him, and the electric sliding door rose slowly, revealing the magnificent, clean, busy and orderly large-scale production workshop inside. At the same time, Liu Chun's proud Shanghai stock market accent sounded again: "welcome to Tengfei group. It took three years to complete the pulsating assembly workshop of turbofan engine."

Then he reached out and motioned to the huge Suspended Top automatic slide in the workshop. Immediately, a string of wd-30s turbofan engines hanging horizontally along the suspended top automatic slide came into the public's eyes.

Some of them have just been assembled from the foundation, some have assembled the core machine, some have stacked the turbine blades, and some have assembled the compressor and transmission shaft.

However, no matter which process, the wd-30s turbofan engine is placed horizontally. After the assembly of each station is completed, the suspended top will slide forward, and the assembly engine of this station will automatically run to the next station, and then the workers of this station continue to repeat the same work.

"This This This... "

Seeing this scene, the former Air Force Chief's eyes were wide open. He couldn't help it. The scene in front of him was so different from the traditional way of assembling an aeroengine in a parking lot like a string of sugar gourds that he didn't know how to express his cognition.

The head of the headquarters is the same. After a few surprised glances, he turns to Zhuang Jianye and asks, "can aeroengine also use pulse production line?"

Zhuang Jianye nodded with a smile: "yes, Hangfa can also pulse!"
