Chapter 1451

The on-site experts and the leaders and leaders of the Navy understood that the original three-dimensional design and manufacturing technology and online related design technology based on model definition actually removed the most cumbersome and time-consuming paper templates and two-dimensional plane engineering drawings in the design, production and manufacturing process.

For people who are familiar with aviation R & D and manufacturing, it's just like hearing that China can break away from the circle of friends in developing countries and enter the ranks of developed countries to make friends tomorrow. Do you think you're dreaming and cancel what has been used for decades?

It's no wonder that the people in the field can't turn this corner for a moment. Since the establishment of the aviation industry, major aviation development units and manufacturers in China have basically adopted mold line samples, paper two digit engineering drawings and parts and components lists to express aircraft products.

Due to the large number of product drawings and tooling drawings, the process designers of the manufacturing unit must have high drawing ability and great patience to complete process review, assembly design, process coordination and material statistics.

At the same time, the expressiveness of two-dimensional drawings is limited, and there are many uncoordinated places in the design itself, resulting in the workload and time-consuming of process design. Many uncoordinated problems in products, tooling and process can only be found when they are actually manufactured.

Because of this, these old craftsmen and technicians from the grass-roots level of aviation manufacturers have developed a pair of golden eyes and a stable and rigorous character.

Although today, I think back to the days when I was young, sitting in the cold craft room and looking at the drawings; But in the future work, the eyesight and character they developed during that time helped them overcome many difficulties. Because of this, they often miss the drawings that tortured them to sleep well.

I thought this model would last for more than half a century, but I didn't think that the two technologies developed by China's take-off had directly swept the two-dimensional drawings and assembly instruction documents crucial to aviation development and production into the pile of historical papers. The impact on the Three Outlooks was so shocking that Zhuang Jianye's introduction had come to an end, Everyone present did not return from this shock.

Of course, Zhuang Jianye, as the initiator of the terracotta warriors, is not prepared to let these people really taste it again. The highest level of loading 13 is dimensionality reduction and attack. There are a lot of things at the bottom of China's take-off pressure box, such as a launch test of an air launched carrier rocket using the improved hong-6 not long ago, This proves the feasibility of launching small satellites in low orbit by air launched solid launch vehicles.

Of course, replacing the satellite with a hypersonic mobile warhead, supplemented by precision guidance devices, is an anti-ship ballistic missile with strong lethality.

For another example, the rocket ramjet turbojet hybrid engine using the shock wind tunnel has made a substantive breakthrough. This technology is mainly aimed at the supporting project of the interception scheme of the "dawn goddess" high-altitude strategic reconnaissance aircraft replacing the "blackbird" high-altitude strategic reconnaissance aircraft.

According to the public news between liberty and beauty, the "dawn goddess" high-altitude strategic reconnaissance aircraft is an advanced aircraft that can fly rapidly in suborbital space 60 to 80 kilometers away from the ground at Mach 6 ultra-high sound speed.

Not only does the speed and height far exceed the "blackbird", but more importantly, freedom Meijian intends to transform this strategic reconnaissance aircraft into a strategic bomber that can carry out global rapid attack.

The headquarters' judgment is that the free beauty room can fully realize all the assumptions of the "dawn goddess" high-altitude strategic reconnaissance aircraft in terms of technical scheme and implementation conditions. Therefore, it has to be prevented. At least there should be a modern interception system that can carry out sub orbital free orbit transfer and has a high supersonic speed of more than Mach 8.

Since China Tengfei is the only one in China that spans the two major businesses of aviation and aerospace, and has advanced experience in the development of shock wind tunnel and variable cycle engine, the headquarters sold the total power of variable orbit hypersonic interception system to China Tengfei.

Zhuang Jianye's ambition in this regard is not only to intercept the "goddess of dawn", but to tap the potential of this technology through the investment of the headquarters.

At the very least, it is necessary to improve the reliability of the powertrain and make it extremely reusable. In this way, whether it is the future military suborbital aircraft or the civil suborbital weightless tourism experience project, China will be able to take off easily, and may even rewrite the history of aerospace development and become a trendsetter leading the new generation of aerospace technology.

……

The problem is that most of these technologies are protected by the strict confidentiality system, and even the experts at the headquarters and the head of the navy have no right to know.

If you can't take the best B, you can only choose an ordinary B. otherwise, in such a general past, people can't think that China's take-off is just like this. It's no big deal. How can you upgrade the shipborne aircraft development team to a shipborne Aircraft Research Institute at that time? How to get the Navy's shipboard aircraft project in hand?

If you want to make a conclusion and sleep, you have to make a... Small move.

Therefore, Zhuang Jianye did not dare to let the experts and leaders on the scene think more and must be brainwashed away. Therefore, before the people reacted, Zhuang Jianye waved. The staff of the 10 ton vibration test-bed let out the two computer monitors and immediately said to the people, "please look..."

The experts and leaders immediately gathered around and saw the three-dimensional design drawing of the front fuselage of the fc-23 shipborne heavy fighter on the screen. With Zhuang Jianye clicking, he tapped the keyboard several times, and then entered. The screen quickly switched to show the layout of a section of oxygen maintenance system pipeline.

Different from the previous computer design drawings, what is presented on the screen at the moment is an accurate three-dimensional diagram, which not only includes the material of the pipeline, the installation position, the position and accuracy of drilling, the tolerance, and even the treatment of dust.

Many of those present worked step by step from the technicians of the aviation factory. They only saw how to install the pipeline and what the final effect was.

After all, the three-dimensional model structure is much more intuitive than the two-dimensional drawing, especially the small holes on the side. You can see them clearly by sliding the mouse a few times, and then you can process them accurately compared with the real workpiece.

Unlike two-dimensional drawings and stereotyped planes, if you want to understand, you have to have very excellent spatial imagination. At least build a three-dimensional structure in your mind, which is very personal for front-line workers!

Of course, this is not the most important. The key is that the parameters and data on the screen can be transmitted to the large touch screen opposite in real time. Technicians can wear the virtual reality imaging system and carry out the digital pre installation of this pipeline on the touch screen, so as to check whether the design matches the actual process, and can be quickly improved in this process.

The data synchronously improves other structures involved in fc-23 through online correlation design technology, without the back and forth wrangling between workshops and design units as before

Seeing this, the leader of the expert group could no longer control his emotions and pointed to the screen in disbelief: "this... This... This... This is really what we did?"
