This situation is what Djokovic, the Russian aviation industry's knowledgeable people, most want to see. The question is whether they have the ability to stop it?

Perhaps in the Soviet era, with its strong military and political influence, we could still hold down ambitious people like China Tengfei Group who were ready to divide the sphere of Russian economic influence.

But now, Russia, which inherited the vast majority of the Soviet Union's legacy, not only did not go as promised by politicians, but would strengthen its prosperity if it failed to see itself collapse. In this case, domestic problems were unstable, so how could it radiate to the surrounding areas?

Just as Djokovic and others stared at the WD-60ML-22 turbofan engine in a daze, thinking about how to face the competition of Tengfei Group, the rising star, in the future, and how to break the deadlock, Liu Cong suddenly coughed lightly and said something that made Djokovic even more frightened:

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

It will use the modified H-ZB900 composite material that combines high strength and ultra-high toughness. Remember what I said just now, it is ultra-high toughness rather than the high toughness of H-ZB800 at this stage."

After setting a key point for the people present, Liu Cong paused, as if he really regarded Djokovic and others as students, deliberately letting them digest what they had 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 22 pieces to 18 pieces, which will further improve the operating efficiency of the first-stage fan while reducing the engine weight.

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 large thrust engine, our Tengfei Group will launch a large civilian passenger aircraft with a maximum take-off weight of 120 tons and carrying 240 passengers. Xiao Wang~~~ takes out the information."

With Liu Cong's instructions, several staff members acted immediately, like magic, and placed a bracket on the engine test bench, putting the drawing board and the engineering renderings. Liu Cong didn't need to have an instruction stick, but introduced it with his hands and gestures:

"This is our FB-2000 project. The benchmark models are Boeing's 757, Airbus' A321 and McDonnell MD-95. Its biggest feature is that it will be equipped with two WD-60ML-18 turbofan engines, and it will use a large number of advanced composite materials. We initially expect that the composite material usage will reach 30.7%. This value makes our ZNB-2000 the most widely used aircraft in the world..."

Liu Cong's mouth was like a flood that had opened the gate in front of various map boards, and it was a constant roar, but Djokovic, who was standing opposite, could only watch Liu Cong's mouth open and close up, and he could never hear a sound, because at this moment, the old expert from Tupolev's head was like a blowout, buzzing.

In fact, when Liu Cong asked someone to take the picture and saw the renderings of the plane above with the words FB-2000, Djokovic's head exploded.

As the saying goes, laymen watch the excitement, and experts watch the tricks. In my eyes, these renderings taken by Liu Cong will only be praised as "beautiful".

But in the eyes of an insider like Djokovic, every detail in the rendering is worthy of fun.

Not to mention streamlined lines, slender and round fuselage, nor to mention the iconic vertical tail and horizontal tail wing, just to say that every aircraft is essential wings. After reading a few renderings, Djokovic knows that Tengfei Group is not only really good at playing, but also technically at least two generations ahead of the 204 aircraft that they worked hard for.

This is not to say that the supercritical wings that the FB-2000 has applied to the Figure-204, nor does it mean that the wing shape is more like the wing shape of a falcon gliding at high altitude, proving the excellent ability of Tengfei Group in releasing aerodynamic appearance.

But just a few pictures of the pictures FB-2000's wings were slightly upturned when they were still on the ground and flying in the air, Djokovic was blown up like he was hit by five thunder.

You should know that it is a new wing structure developed based on composite materials and a new production process. Compared with traditional wings, they can only resist the help brought by the air during flight under their own structural frame, and achieve different flights in a head-on way of a fierce man from the sky.

This wing is like a soft goddess, using a soft and boneless posture, changing its shape as the air resistance is strong, thereby adapting to or even utilizing air resistance, making the aircraft have better flight performance.

In other words, this type of wing is more like the wings of a falcon, and the wings can be adjusted according to different speeds and heights.

Human flight starts by imitating birds. When aviation engineers continue to study bird flights, they naturally notice that bird wings adjust themselves with different air resistance, so they naturally want to apply them to the aircraft.

Unfortunately, due to the fact that materials and manufacturing processes have never been realized, it was known that this technology was considered to be possible after NASA used composite materials to make equal proportional flexible wings and successfully tested them.

The benefits brought by this technology after application are simply subversive. First, it is fuel saving, and secondly, it is to reduce the total structure of the aircraft, and the ability to fly again can be improved, the noise can be reduced again, the aircraft will be more stable again, and again...

In short, there are a lot of benefits, otherwise the evolution of birds for billions of years would be in vain.

Boeing received the first month of water, and immediately purchased the patent from NASA, and then further researched it and applied it to the latest Boeing 777.

Airbus is unwilling to fall behind, but he has no choice but to gather all European forces to work hard to solve the problem.

The former Soviet Union\Russia of course also noticed this epoch-making technology that could change the pattern of civil aviation passenger aircraft. If you want to follow up, you will break it all the way.

However, what Djokovic never expected was that the former student was always following the Soviet Union's butt to steal the blame, and it also seemed to have made great progress.

If he had been to Tengfei Group, Djokovic would not believe that China could make such flexible wings. However, after he looked at the fourth-generation fan blades and learned about composite fan blades and the WD-60ML-22 turbofan engine of the D-30KP turbofan engine with a technical level far exceeding that of the D-30KP turbofan engine, the distrust that lingers in his heart was long gone by him, leaving only deep fear.
