    This situation is what Djokovic and other knowledgeable people in the Russian aviation industry least want to see. The question is, do they have the ability to stop it?

    ¡°Perhaps in the Soviet era, with its strong military strength and political influence, it could still hold back careerists like China Ascendas Group who were ready to carve up Russia¡¯s economic sphere of influence.

    But now, instead of inheriting most of the legacy of the Soviet Union, Russia has not become more powerful after the collapse of the Soviet Union, as politicians promised. On the contrary, the powerful country did not see that it is becoming more and more collapsed. In this case, domestic  If all the problems cannot be solved, how can we radiate to the surrounding areas?

    Just when Djokovic and others were staring blankly at the WD-60ml-22 turbofan engine, thinking about how to face the competition from the rising star of Ascendas Group in the future and how to break the situation, Liu Cong suddenly coughed lightly and said  Djokovic said something that made him even more frightened:

    "Next, we will further improve on the basis of the wd-60ml-22 turbofan engine. The current plan has been launched, and some areas have entered the engineering implementation stage. It will be the ultimate model of our wd-60ml series, wd-  60ml-18 turbofan engine.

    It will use the improved h-zb900 type fan blades made of composite materials with both high strength and ultra-high toughness. Everyone, remember what I just said, it is ultra-high toughness rather than the high toughness of the current h-zb800.  "

    After giving some key points to those present, Liu Cong paused for a moment. He seemed to really regard Djokovic and others as students and deliberately let them digest what he just said.

    Djokovic and others really cooperated and frowned, and a bad premonition immediately came to their hearts.

    Sure enough, the next moment Liu Cong broke out a shocking news: "Based on this, we will reduce the first-stage fan blades of the WD-60ml series turbofan engine from the current 22 to 18, while reducing the weight of the engine.  , further improving the operating efficiency of the first-level fan.

    By then, the bypass ratio of this wd-60ml-18 turbofan engine will reach 11, thereby expanding the fan diameter to 2.1 meters, and the maximum thrust will exceed 16 tons. Based on this high-thrust engine, our Ascendas Group  A large civilian passenger aircraft with a maximum take-off weight of 120 tons and a capacity of 240 passengers will be launched. Xiao Wang~~~ took out the information.  "

    Following Liu Cong's instructions, several staff members acted immediately, and like magic, they placed brackets on the engine test bench and placed drawing boards and engineering renderings. Liu Cong did not use a pointing stick, but used his own hands to connect  The gesture belt introduces it as follows:

    "This is our fcnb-2000 project. The target aircraft are Boeing's 757, Airbus's A321 and McDonnell Douglas MD-95. In addition to being equipped with two wd-60ml-18 turbofan engines, its biggest feature is that it will  Using a large amount of advanced composite materials, we initially estimate that the amount of composite materials will reach 30.7%. This value makes our znb-2000 the aircraft with the most composite materials in the world"

    Liu Cong's mouth was like a flood in front of various picture boards. He could not stop talking, but Djokovic standing opposite could only watch Liu Cong's mouth open and close.  There was never a sound, because the old expert from Tupolev's head was buzzing as if it was exploding.

    In fact, when Liu Cong asked someone to bring up the drawing board and saw the rendering of the aircraft with the words fcnb-2000 painted on it, Djokovic¡¯s head exploded.

    As the saying goes, laymen watch the excitement, and experts watch the door. In my eyes, these renderings Liu Cong took out will only be praised as "beautiful" at best.

    But in the eyes of an expert like Djokovic, every detail on the renderings is worth pondering.

    Not to mention the streamlined, slender yet rounded fuselage, nor the iconic vertical tail and horizontal tail, let¡¯s just say that wings are essential for every aircraft. Looking at a few renderings, Djokovic looks like  You know, Ascendas Group is not only playing for real, but also technically at least two generations ahead of the Tu-204 aircraft they are working hard to achieve.

    This is not to say that the fcnb-2000 uses a supercritical wing that is not used in the Tu-204, nor does it mean that the wing shape is more like the shape of an eagle gliding at high altitude with its wings spread, proving the Ascendas Group's excellent performance in releasing aerodynamic shapes.  ability.

    But just a few pictures show the slight upward angle of the wings of fcnb-2000 when it is stationary on the ground and flying in the air, making Djokovic as if he was hit by five thunders, which was burnt on the outside and tender on the inside.

    You must know that it is a brand-new wing structure developed based on composite materials and a new production process. Compared with traditional wings, it can only resist the assistance brought by the air during flight under its own structural frame.  A head-on approach to flying is different.

    This kind of wing is like a soft goddess, with a weak and boneless posture, changing its shape according to the strength of air resistance.?? shape, thereby adapting to and even utilizing air resistance, giving the aircraft better flight performance.

    In other words, this kind of wing is more like the wings of an eagle. It can adjust the height and height of the wings according to different speeds and different heights.

    Human flight began by imitating birds. When aerospace engineers continued to study bird flight, they naturally noticed that bird wings self-adjust with different air resistances, and naturally wanted to apply it to aircraft.

    " Unfortunately, due to materials and manufacturing processes, it has never been possible. It was only after NASA used composite materials to make proportional flexible wings in the late 1980s and successfully tested them that this technology became possible.

    The benefits brought by the application of this technology are simply disruptive. Firstly, it saves fuel. Secondly, it reduces the total structural weight of the aircraft. Once again, the flight performance is improved. Once again, the noise is reduced. Once again, the aircraft is more stable. Again

    All in all, there are a lot of benefits, otherwise the hundreds of millions of years of evolution of birds would have been in vain.

    ??Boeing was first to come, and immediately purchased this patent from NASA, and then further studied it and applied it to the latest Boeing 777.

    Airbus is not willing to lag behind, but it is technically one step behind, so it can only gather the power of all Europe to desperately tackle the problem.

    Of course, the former Soviet Union and Russia also noticed this epoch-making technology that could change the pattern of civil aviation. They wanted to follow up, but they themselves were shattered first.

    However, what Djokovic never expected was that China, his former student who had always followed the Soviet Union and secretly copied it, was also aiming in this direction, and seemed to have made great progress.

    Before coming to Ascendas Group, Djokovic would never have believed that China could make such a flexible wing. But when he saw the fourth-generation fan blades, he understood the composite fan blades and the technological level.  After surpassing the D-30kp turbofan engine and the WD-60ml-22 turbofan engine, the distrust that lingered in his heart had long been thrown away, leaving only deep fear.

    If this is done by Ascendas Group, wouldn¡¯t the Russian civil aviation industry be finished?
