Chapter 1451 It¡¯s just a trick at best

Previous page        Return to Catalog        Next page

    The experts on site and the leaders and chiefs of the navy understood when they heard this. It turns out that the three-dimensional design and manufacturing technology and online associated design technology based on model definition actually combine the most tedious and time-consuming paper templates and paper templates in the design and production manufacturing process.  The two-dimensional plan engineering drawing has been removed.

    For those who are well versed in aviation R&D and manufacturing, this is just like hearing that tomorrow China will be able to leave the circle of friends of developing countries and advance into the ranks of developed countries to make friends. They wonder if they are dreaming.  Can something that has been built for decades be canceled just like that?

    It¡¯s no wonder that everyone in the venue couldn¡¯t turn this corner for a while. In fact, since the day the aviation industry was established, all major domestic aviation research units and production plants have basically used mold line templates, paper two-digit engineering drawings and component parts lists.  To express aircraft products.

    Because the number of product drawings and tooling drawings is very large, 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 the design itself has many incongruities, which results in a very heavy workload and very long time consumption in process design. Many incoordination issues in products, tooling, and processes cannot be solved until actual manufacturing.  Only then was it discovered.

    Because of this, these old craftsmen and technicians who came from the grassroots level of the aviation manufacturing plant have developed a pair of sharp eyes and a steady and rigorous character.

    Although they still shudder when they recall the days when they were young, sitting in the cold craft room and looking at the drawings; but in their future work, the vision and character they developed during that time helped them overcome many difficulties.  , and because of this, every time I think about it, I feel a little nostalgic for the drawings that tortured them so much that they couldn't even sleep well.

    I thought that this model would continue for more than half a century, but I didn't expect that the two technologies developed by China Tengfei actually swept the two-dimensional drawings and assembly instruction documents that are crucial in aviation development and production directly into the pile of historical old papers.  This kind of impact on three views was so shocking that Zhuang Jianye's introduction had come to an end, and no one present had recovered from this shock.

    Of course, Zhuang Jianye, as the initiator, was not prepared to let this group of people really think about it. The highest level of pretending to be 13 is dimensionality reduction. To say that there are really a lot of things under the pressure of China's take-off nowadays, such as the former  Soon, a launch test of an air-launched carrier rocket using an improved H-6 confirmed the feasibility of air-launched solid carrier rockets for launching low-orbit small satellites.

    Of course, if the satellite is replaced with a hypersonic maneuverable warhead, supplemented by a precision guidance device, it will be an extremely lethal anti-ship ballistic missile.

    Another example is the use of shock wave wind tunnels to achieve substantial breakthroughs in rocket-ramjet-turbojet hybrid engines. This technology is mainly aimed at the "Dawn Goddess" high-altitude strategic reconnaissance aircraft that replaces the "Blackbird" high-altitude strategic reconnaissance aircraft.  Supporting project of the aircraft interception program.

    According to the information disclosed by the Free and Beautiful Room, the "Dawn Goddess" high-altitude strategic reconnaissance aircraft is an advanced aviation aircraft that can fly rapidly in suborbital space 60 to 80 kilometers above the ground at Mach 6 supersonic speed.

    Not only is the speed and altitude far greater than the "Blackbird", but more importantly, Free and Beautiful intends to transform this strategic reconnaissance aircraft into a strategic bomber that can carry out rapid global strikes.

    The headquarters¡¯ judgment on this is that the Free Beautiful Space can completely realize all the ideas of the "Dawn Goddess" high-altitude strategic reconnaissance aircraft in terms of technical solutions and implementation conditions. Therefore, it has to be guarded against. At least there must be one that can freely change suborbital orbits and has the characteristics  Modern interception system for hypersonic speeds above Mach 8.

    Since China Ascendas is the only company in China that spans the two major businesses of aviation and aerospace, and has experience in the development of advanced shock wave wind tunnels and variable cycle engines, the headquarters handed over the power assembly of the variable orbit hypersonic interception system to China  Take off.

    Zhuang Jianye¡¯s ambition in this regard is not just to intercept the ¡°Dawn Goddess¡±, but to tap into the potential of this technology through the headquarters¡¯ investment.

    At the very least, the reliability of the powertrain must be improved and made extremely reusable. In this way, whether it is a future military suborbital aircraft or a civilian suborbital weightless sightseeing experience project, China Takeoff will be able to do so with ease, and even  It is possible to rewrite the history of aerospace development and become a trendsetter in leading a new generation of aerospace technology.

    ¡­¡­

    Similar black technologies and new technologies can be said to be taking off in large numbers in China today. The problem is that most of these technologies are protected by a strict confidentiality system. Even the experts at the headquarters and the heads of the navy have no authority.  Know.

    You can¡¯t take the best one, just the one who is the bestIf you can pick someone who is average and awesome, otherwise it will just pass by like this, and people will not think that China's take-off is just this, it is not a big deal. How will the carrier-based aircraft development group be upgraded to a carrier-based aircraft research institute by then?  How to get the Navy's carrier-based aircraft project into your hands without any problems?

    ¡° If you want to seal the coffin, if you want to settle the matter overnight, you have to use a little trick

    Therefore, Zhuang Jianye did not dare to let the experts and leaders on the scene think too much. They had to be brainwashed and taken away. So before everyone could react, Zhuang Jianye waved and the staff of the 10-ton vibration test bench gave up two computer monitors.  He said to everyone: "Everyone, please take a look"

    The experts and leaders present immediately gathered around and saw on the screen a three-dimensional design drawing of the front fuselage of the fc-23 carrier-based heavy fighter. As Zhuang Jianye clicked on the keyboard a few times and then pressed Enter, the screen quickly switched.  , showing the layout of a section of oxygen maintenance system piping.

    Different from the previous computer design drawings, what is now displayed on the screen is a precise three-dimensional drawing, which not only includes the material of the pipeline, the installation position, the position and accuracy of drilling holes, tolerances, and even dust treatment.  There is a description.

    Many people present had worked step by step as technicians at the aviation factory. After just a few glances, they knew how to install the pipeline and what the final effect would be.

    After all, the three-dimensional model structure is much more intuitive than the two-dimensional drawings, especially the small holes on the side. You can clearly see it by sliding the mouse a few times, and then you can accurately compare it with the actual workpiece.  processing.

    Unlike two-dimensional drawings, which are uniform planes, if you want to understand them, you must have excellent spatial imagination. At the very least, you must construct a three-dimensional structure in your mind. This is literally life-threatening for front-line workers!

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

    The data is used to simultaneously improve other structures involved in fc-23 through online associated design technology, eliminating the need to go back and forth between workshops and design units like before

    Seeing this, the leader of the expert team could no longer control his emotions and pointed at the screen in disbelief: "Thisthisthisis this really what we did?"
