Chapter 622: Aviation engines can also pulse

Previous page        Return to Catalog        Next page

    It¡¯s no wonder that the head of the Air Force is like this, because according to the scale of Tengfei Aviation Power¡¯s production of wd-30s turbofan engines, the annual production capacity of one hundred units is already a very powerful figure.

    After all, the factory area surrounding the entire No. 0 assembly line is only more than 50,000 square meters, and it is also divided into several supporting processing workshops. The area left for the assembly workshop is further reduced.

    The assembly of aero engines, especially turbofan engines, is a high-end production process that combines fine adjustment and complex processes. In many places, it is difficult to do it quickly, otherwise even if it is assembled and produced, it will leave a huge safety gap.  Hidden danger.

    Because of this, around the world, engine assembly is a slow and meticulous work. The average time to assemble an engine regardless of size is more than a month.

    Among them, CEF International, a joint venture between General Motors of the United States and Snecma of France, produces the Leap series of high-bypass turbofan engines with the fastest assembly efficiency, but it still takes 35 days to complete one Leap engine.  Turbofan engine assembly process.

    The U.S. company Pratt & Whitney is slightly worse. It usually takes 45 to 50 days to assemble a turbofan engine. The British company Rolls-Royce is about the same as Pratt & Whitney. As for other countries, it takes 50 days to assemble an engine, which is considered very fast.

    Not to mention anything else, the average final assembly time of the Spey turbofan engine used by the Northwest Aviation Development Plant on a fighter-bomber is 62 days. In other words, even if all the parts are there and installed one by one, it still takes  It takes two months to install a usable aero engine.

    If you add in the factory performance test of more than half a month, you can imagine how much production capacity will be this year. It is not an exaggeration to describe it as pitiful.

    The wd-30s turbofan engine produced by Ascendas Group is not as large as the above-mentioned large and medium-sized turbofan engines, but it is limited to the size of the special tooling fixtures and fixed workstations for assembly, but the process is similar, that is to say, large  There is no difference in the final assembly and assembly procedures of the aviation turbofan engine on the wd-30s turbofan engine.

    Under such circumstances, how does Ascendas Aviation Power achieve an annual output of 400 wd-30s turbofan engines?

    You must know that according to the area of ??the No. 0 assembly workshop, it can provide up to 20 assembly stations. Based on the fastest assembly of one engine per month, the production capacity is only 20 units a month, and only 240 units a year. The problem is  This is the most ideal theoretical situation. Even the world's top CEF international company cannot assemble one unit in 30 days. How can Tengfei Aviation Power be more powerful than the world's top aviation engine company?

    Is it self-bragging, or is it just daydreaming when you get some results?

    Based on this, after the surprised exclamation, the Air Force chief who asked the question immediately calmed down and looked at Liu Chun with a very strange look, as if looking at a very ordinary old comrade who likes to talk. Although he did not refute,  But it¡¯s full of tolerance from the inside out.

    Not only the chief of the Air Force, but also leaders and chiefs who have a little knowledge of the aviation industry all have this mentality. After all, the head of the headquarters is there, and Ascendas Aviation Power also performed well enough during the workshop inspection just now.

    At this time, it is normal and routine to brag a little, shout slogans, and strive for more funds and money from higher-level departments.

    ¡°Compared to other companies that can push their production capacity to the sky, Ascendas Aviation Power is considered conscientious.

    "When did you become so reserved in asking for funds?"

    The other leaders and chiefs thought this way, and the head of the headquarters was not exempt from this, but he still knew a little about Zhuang Jianye, so he asked with a smile.

    When Zhuang Jianye heard this, his head was really full of black threads. Didn¡¯t their Ascendas Group pull their bodies below the altitude line when they went to the capital to ask for funds?  Is it possible that they always have to fight with the major departments in the capital to get it?

    Therefore, Zhuang Jianye quickly explained: "Chief, what you said scared me. Our group has always been conscientious and abiding by laws and regulations. When it comes to funding issues, we have applied legally in accordance with the requirements of our superiors."

    "At the beginning of that year, who was like a dog-skin plaster that blocked me outside the headquarters for more than half a month, and only gave up after stealing 100 million yuan?" The head of the headquarters glanced at Zhuang Jianye and asked expressionlessly.

    Zhuang Jianye was startled for a moment, as if he knew about this for the first time, and exclaimed: "There is such a bad thing? Why didn't I know about it? Chief, it's a rumor, it's definitely a rumor. I am a leader of a key enterprise under a ministry.  How could he do such a shameless thing?

    Chief, if you have any photos or videos, give them to me. I will go to court and sue him directly. I, Zhuang Jianye, have never seen such a shameless person in my more than 30 years of life.  "

    The words are loud and clear,He was so impassioned that he was about to carry a bag of explosives and die with the enemy. However, these remarks made several people around the head of the headquarters dumbfounded. They had seen shameless people, but never such shameless people. It was clearly you, Zhuang Jianye, who did it.  If you still don't admit it, do you still want to show that face?

    ????????????????????????? But I was surprised, and I couldn¡¯t say anything to refute it, because Zhuang Jianye made it very clear, is there a photo or a video, how can I identify it if there is nothing?

    Nima~~I finally saw what a shameless person is.

    The head of the headquarters was not surprised at all. He just smiled slightly after hearing Zhuang Jianye's words, then looked around and frowned: "This doesn't seem to be the way back?"

    Zhuang Jianye smiled slightly: "Yes."

    As soon as he finished speaking, he saw a flash of lightning in front of him. The sliding door slowly rose up, revealing the magnificent, clean, busy and orderly large-scale production workshop inside. At the same time, Liu Chun's proud Shanghainese accent sounded again: "Welcome  It took three years after I came to Ascendas Group to build the turbofan engine pulsating assembly production workshop."

    Speaking of the huge suspended automatic sliding rail in the workshop, he immediately gained a string, and immediately a string of WD -30S turbofan engines hanging along the suspension of the suspended slider was caught by everyone.

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

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

    "Thisthisthis"

    Seeing this scene, the former Air Force chief's eyes widened in disbelief. He had no choice but to see that the scene in front of him was so different from the traditional candied haws-on-a-stick assembly method in a parking lot that he recognized it.  Those who know subversion don¡¯t know how to express it.

    The head of the headquarters was the same. After looking at it for a few times in surprise, he turned to Zhuang Jianye and asked: "Can aerospace engines also use pulse production lines?"

    Zhuang Jianye smiled and nodded: "Yes, aviation engines can also pulse!"
