Take Off My Aviation Era

Others are unbelievable, but the Brazilian Aerospace Agency experts such as Edo'o and Creeldo understand that the biggest gain from their trip to China may be this JSNB-Ⅱ integrated aviation and aerospace analysis system. Up.

Although this system makes Park Mingzhe, Badia and others misunderstood, it is a rare treasure in the eyes of Edo'o and Creeldo, and even their Brazilian aviation and aerospace The only world-class advanced production tools in this field.

Because this digital production tool using virtual manufacturing technology has been applied in the hands of industry giants such as Europe and the United States.

The most typical is Boeing. The Boeing 777 passenger aircraft developed by Boeing adopts the virtual manufacturing technology independently developed by Boeing. The research and development cycle that originally took 6 to 8 years to complete took only more than 3 years.

The project was initiated in October 1990 and formally developed in February 1991. In 1993, the engineering prototype was off the assembly line for ground testing. It officially first flew in June this year. It is expected that the first mass production model will be put into operation by the end of next year.

At that time, all kinds of fancy frictions can be made according to the Airbus A340 heads that have not been put into operation for a long time.

Because the cost of the Boeing 777 is lower than that of the A340 when the range is comparable to the load.

This is not only the dual launch of the Boeing 777, which is more advantageous than the four-engine of the A340; it is not that the general-purpose engine of the Boeing 777 is more powerful than the five-engine AUP of the A340. It is because the Boeing 777 is only The three-year research and development cycle has made the manufacturing cost of this model so low that Airbus all kinds of crying in the toilet.

Airbus is also helpless. Although the announced A340 R&D process is only 5 years old, the preliminary demonstration work has taken Airbus more than 4 years, and the concept of parallel development with A330 is also used in the development process. , And borrowed a lot of mature technology of A320 to shorten the development cycle as much as possible.

Hurry up and think about taking advantage of the sluggish market expectations of the Boeing 767, and other models with outdated technology to seize a portion of the market. Who would have thought that as soon as their A330 and A340 twin prides debuted, Boeing would be overwhelmed by lightning. The Boeing 777 was photographed in the eighteen palms of Jianglong.

The speed is simply appalling.

Not to mention anything else, even if you design and produce a car, it will take about 5 years for repeated research and development, but Boeing has achieved even greater efficiency on the 777 than the development of a car. You must know that it is an airplane or a take-off weight. An intercontinental long-distance passenger aircraft of more than 100 tons, carrying hundreds of passengers, flying more than 10,000 kilometers.

There are tens of millions of parts and components, and the design can go around the earth several times, but the efficiency is so powerful, which only shows that Boeing is really powerful.

However, Boeing’s surprise to the outside world was only a slight smile. If it were not because of lack of confidence in the virtual manufacturing technology developed by itself, it temporarily conducted several verification models and conducted comparison experiments for half a year. The entire development process of Boeing 777 was even Will be compressed to about 2 years.

Because the virtual manufacturing used by Boeing completely subverted the parallel manufacturing and agile manufacturing concepts proposed in the 1980s, it integrated Boeing's internal use of powerful industrial software and computer architecture into a purely digital virtual factory.

From design to research and development to tooling and craftsmanship, all parts as large as dozens of tons of structural components, as small as small screws as small as fingernails, can be repeatedly verified in this virtual factory to obtain the best Then, these solutions can be formed into numerical control programs and input into the numerical control machine tools in the workshop to continuously produce products that meet the requirements according to the design ideas.

There was no design drawing in the whole process. It was a complete aircraft architecture composed of five large computers provided by IBM, plus more than 2,000 computer terminals, and more than 5,000 senior designers using a line of data codes. That’s why Boeing 777 is also called a paperless airplane.

In fact, in addition to Boeing, Lockheed Martin also applies this virtual manufacturing technology to the development of a new generation of stealth fighter F-22; Northrop Grumman also uses a similar system to produce B-2 stealth bombers.

Not only that, this kind of virtual manufacturing technology is being used by more American industrial giants in various high-end manufacturing fields such as aircraft carriers, destroyers, aero engines, launch vehicles, etc., thus making the post-Cold War America once again dominates the world in terms of industry and has become a veritable name. The world's high-end factory.

Europe is far behind in this regard. Airbus is a typical example. Although Dassault’s software is excellent enough, it cannot achieve the role of a purely digital virtual factory in the United States. However, it relies on the special relationship between the United States and Europe. Europe is still able to introduce part of the virtual manufacturing technology from the United States and build a semi-virtual manufacturing factory in combination with its own software, which can also be regarded as improving its own efficiency.

As for Russia, which inherits the Soviet heritage...Well, the fighting nations are still hungry, so there is still time to deal with these things.

But whether it is the United States with a full set of technologies, Europe with only half of the technology, or Russia with only the concepts and partial algorithms, each of them regards virtual manufacturing technology as a treasure. Outsiders can see it and want to buy it? Sorry, how much is not for sale!

The Brazilians are forced to work hard here. The reason why Bombardier can launch CRJ-200 first and seize the market is because Bombardier's technical capabilities are so strong?

No, but because they hugged a good thigh, Lockheed Martin in the United States and Airbus in Europe, these two giants with virtual manufacturing technology help Bombardier to design and develop it, it is difficult to imagine the progress of CRJ-200.

Embraer also wants to be fast. The problem is that Bombardier has taken up all the good thighs. The rest of Boeing and Noggle looked at Embraer and the stripped girl, and they wanted to rush on immediately. Eat dry.

Frightened Embraer from the back door ~www.wuxiaspot.com~ ran all over the world to see if I could bump into a dead mouse and find an alternative to save myself.

As a result, this blind cat in Brazil actually encountered a dead mouse.

The JSNB-II comprehensive analysis system for aviation and aerospace, which also applies virtual manufacturing technology, is so-called that there is nowhere to be found through iron shoes, and it is all effortless. How can the Brazilians let go of this golden opportunity?

It is important to know that the most important thing about Brazil's ERJ-140 series regional airliners is time, and the JSNB-Ⅱ aviation and aerospace integrated analysis system is undoubtedly a multiplier that shortens the development time and improves efficiency.

Therefore, both Edo'ao and Creeldo are determined to win the JSNB-Ⅱ integrated aviation and aerospace analysis system.

The problem is that Edo'o, Creedo and others are impatient, but Zhuang Jianye is steady. He looked at the two Brazilian aerospace experts who seemed to be talking about double reeds, and raised his hands: "Two, two, yours. I understand sincerity. Let’s stop and stop first. Then, I’ll say the number, and we’ll set it down if we want to make it. The two sets of simplified versions are affordable enough!"
