Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

It's no wonder that Zhuang Jianye was so surprised. It is true that flexible tooling technology has a pivotal position in the field of modern aviation manufacturing.

As we all know, aircraft manufacturing is a huge and sophisticated system engineering, and because of this, for a long time, aircraft manufacturing has not been able to implement assembly line operations like cars, and can only implement design, manufacturing and final assembly with aircraft models as the core.

Because of this, tooling equipment used to fix, rotate, move, and mold aircraft components are generally designed individually and independently matched to specific aircraft models.

In this mode, although the accuracy and consistency of various parameters during aircraft remanufacturing are ensured, and the aircraft design indicators are well implemented, this kind of tooling kit like a carrot and a pit, so versatility is poor, and there are many limitations. It is often ordered in aircraft models. After the delivery is completed or forced to dismount, these tooling equipment will also withdraw from the stage of history along with the model.

The most typical example in this regard is the tooling equipment of Yunshi. It is not that other factories do not want to use these equipment. The problem is that the tooling equipment of Yunshi can only be applied to the type of aircraft of Yunshi, unless the aircraft manufactured by other factories are compatible with Yunshi. The parameters are exactly the same and can still be used. If you change a little, these fixed tooling equipment will not be used at all.

Therefore, this kind of elimination of a large number of expensive tooling equipment with the discontinuation of models is not a wasteful waste of manufacturers, but a helpless move due to the dual restrictions of production mechanism and technological level.

Is there any tooling equipment that can be applied to different types of aircraft and can be used flexibly for different parts and angles?

Of course, as early as the 1960s, American aviation giants developed a flexible tooling technology based on multi-matrix column vacuum adsorption.

And applied to several different models of aircraft, not only reduced production costs, combined with the high precision of CNC machine tools, but also greatly improved production efficiency, thus bringing the US aircraft production capacity to a new level.

The reason is that this flexible tooling technology's excellent versatility and flexible control angle have allowed American aviation companies to save nearly half of the tooling design time.

The tooling design of traditional aircraft manufacturing is by no means an easy task. In a sense, it is not much easier than aircraft design. Because of this, traditional aircraft manufacturing is not only slow, but also very inefficient. It is completely technology-intensive. An industry that is highly labor-intensive.

The emergence of flexible tooling technology has completely overturned the traditional one-machine-one-type tooling model. Using the scalability of the column matrix, it is as graceful as a human-shaped reflection board in an amusement city. The pre-processed parts can be adjusted according to different models and different parameters. The children can be fixed, moved or even flipped, completely independent of the model and parameters.

It stands to reason that the domestic aviation manufacturing industry will not remain indifferent to such a good thing. It should have been thought of long ago. Moreover, the basic principle of this matrix-type flexible tooling technology is very simple. The human-shaped reflection board in the playground of later generations is the same. principle.

But after so many years, the entire world, except for the United States, has no similar technology, even the Soviet Union, which is also among the superpowers. Although Europe has applied flexible tooling technology to produce its own passenger aircraft, it still uses the United States. equipment.

Such a simple principle can only be done by the United States. It is incredible to think about it, but I have to be relieved to investigate it carefully, because this technology, like aero engines, is not based on the principle, but on the core precision measurement and control technology. on.

It is important to know that any part of the airplane is the optimal solution obtained through complex calculations. When the child lays down on the human-shaped reflection board full of pillars in the playground, he can outline a humanoid silhouette. If the parts of the airplane are So casual, it is impossible for aircraft manufacturing to become a clear high-end industry that only a few countries can play.

Because of this, the key to flexible tooling technology is that each matrix column raises its geometry when fixing the components, stretches and shrinks slightly, whether to stay still, or to adjust in multiple directions.

This seemingly simple change, it is obviously unrealistic to use only human testing and calculations. The small parts are okay, just like the Boeing 747 airliner; the C-5 strategic transport aircraft; the B-52 strategic bomber. How many people can Measure out one column by column?

Of course, even if you are not afraid of strenuous work and use manpower to fill in, it is really measured, but after all, people are not mechanical, and there are always naps. When you are confused, in case you accidentally walk away during the measurement, the data is a little worse. With a decimal point, the consequence may be plane crash and death.

Because of this, the flexible tooling equipment must have a comprehensive control system that integrates position control, precise measurement, and mobile positioning.

In this regard, the United States is the only one in the world, and because of this, their flexible tooling technology can lead the world.

There were similar projects in China in the 1970s, but because the entire control system was too complicated, especially in the application of computers, the parts database of domestic aircraft models was completely blank, so after a few years of stuck, I had to give up.

Not to mention the domestic, the Soviet Union, which can compete with the United States in the aviation field, is not as good as the United States in this respect. Otherwise, the later the Cold War, the more the Soviet Union was left behind by the United States in the aviation field, not only in terms of aircraft design. That is, the production capacity that the Soviet Union is proud of can't keep up with the Americans. The root lies here.

A set of tooling Americans can make six models and more than forty parts. The Soviet Union can only make one model with two or three parts. The efficiency and cost of them are simply not the same. It is strange if it is not backward.

Fortunately, the Soviet Union can't change its technology, so it will fight brute force. As long as it can fly the plane into the sky, the manufacturing cost and efficiency will not be a problem.

The Soviet Union can play this way, but the domestic aviation industry can't mess around with the Soviet Union. First, no one is so rich and powerful. Second, reforms have also made the domestic aviation industry gradually understand the importance of benefits~www.readwn.com~especially Tengfei Factory , Is almost a typical representative in the eyes of making money, so Zhuang Jianye has long wanted to work on tooling to further reduce costs.

No way, now Ascendas Factory produces a total of five drone models, and it actually uses four sets of different tooling equipment, which is equivalent to spending three extra money, that’s all, if one of the drones stops production someday , The heavy money to build tooling equipment also loses its value, which is another big waste.

Based on this, Zhuang Jianye really wants to bring flexible tooling technology to the Ascendas plant to improve efficiency and reduce costs. The problem is that he has this intention, but no one gives this opportunity.

The Americans take this seriously. After all, the backbone of the United States dominating the world is the aviation manufacturing industry, and what supports their aviation manufacturing industry is their unique global aviation manufacturing technology.

It is precisely because of this that these things are really not what you want to buy, others can sell you. Zhuang Jianye hoped to get a set of equipment back through different channels.

But just when he had nothing to do and was about to wait another two years to do it by himself, Father Lindeman unexpectedly threw this gift over, which really surprised Zhuang Jianye.
