C2160 Yf120 Reconstruction
For the people of Y Country, they had their own reasons. Although the J58 was a cross-era engine with a cyclical design, however, this kind of engine was produced in the 1960s after all. It was now in the late 1980s. Twenty years had passed, and the once advanced engine had already fallen behind. This was also one of the reasons why they were able to produce it.0
Of course, this was only one aspect. Another factor was that the people of Y Country already had a new type of cyclic engine!
This kind of early engine had many shortcomings. As a combination of Turbojet Engine and Ramjet, it had many shortcomings. It had many problems with connecting at a high and low speed. At that time, there was no advanced digital control technology. It was difficult to control the entire engine precisely. For Y Country, this engine was just a primer.
General Electric had been obsessed with the Cyclic Engine. Now, it was in the new generation of fighter jets in Y Country. There were two prototype machines competing with each other. This was YF22 and YF23. Among them, YF23 was even more sci-fi. Other than its design being more advanced, it was also more futuristic. For example, the unique V-shaped tail had also adopted a new engine.
"President Qin is right. Our intelligence personnel got some information from Y Country." General Lin said, "The people of Y Country prepared two engines for the next model of the plane. One is a regular Turbofan Engine, codenamed YF119. The other is a cyclic engine, codenamed YF120."
General Lin waited for Qin Guan to come here before he threw out this news. Obviously, he also supported this idea. The people of Y Country were willing to give this kind of engine to them because they already had a more advanced engine.
This news made Qin Guan stunned for a moment. It was not because Qin Guan did not know about it. It was because Qin Guan didn't think that his own intelligence department would be so well-informed that they would investigate so much about the construction of the fourth generation machines in Y Country. One should know that this was still a secret.
It was funny to say that in this competition, Lockheed's YF-22 and Phui Company's YF119 won and became the F-22 fighter aircraft and F119 engine. Y Country Air Force originally pursued advanced technology and greatness. In the end, the YF23 with science fictional technology and this super advanced YF120. In the end, they failed.
The people of Y Country must have suffered enough losses on the F-15 engine. Once bitten by a snake for ten years, they would be afraid of rope.
Now, General Lin has made his stance clear. We must not fall behind!
Changing the cycle engine is about to become a trend in the future!
Although they are both cyclical, YF120 and J58, j58 was a Turbojet Engine. When the cyclic cycle was changed, the airflow did not pass through the pressure in front and only went to the combustion room in the back. Under the high speed, the air itself had already been compressed. This was the change in circulation between the vortex and the Ramjet.
As for the YF 120, it was for the fighter aircraft to use. It circulated back and forth between the turbine jet and the Turbofan Engine.
The Turbojet Engine was something commonly used in the past. This type of engine had a small area to withstand the wind. Therefore, it had a very high altitude performance. It was a small plane like the MiG 21. It could also achieve the maximum speed of 2 Mach, which was inseparable from the Turbojet Engine. However, this kind of engine had its shortcomings. This was the cost of fuel. If one added an Outer Culvert outside, it would turn into a turbine fan. The fuel consumption rate was greatly reduced. The engine of the third-generation console... It had to be a turbine fan. Otherwise, the flight would be a mess. At the same time, the thrust was also much greater than a turbine jet.
However, not all turbine fans were good points. Due to the addition of the Outer Culvert, this type of engine had a larger area to withstand the wind. This increased the resistance, especially when it was at high speed. The Outer Culvert did not have any benefits. Instead, it became a type of resistance.
Therefore, the reason why the high altitude performance of the Spey Engine was a mess was because of the fan in front of it. As for the MiG 31 engine, it had been upgraded to a turbine fan. Although the flight speed had been increased, however, the maximum speed of the fan had been slowed down. It was much slower than the MiG 25 that used the turbine. That was the logic.
In order to develop the advanced 4th generation console, the people of Y Country also used all of their technological power. In terms of engines, the YF120 engine was clearly a more sci-fi type.
The F119 engine used a large number of the most advanced technologies. It was the world's first engine with a weight ratio of 10, but it was still just a normal low-connotation Turbofan Engine.
As for the YF120? It used a live door to control it. When needed, it could open the Outer Culvert. The function of the turbine fan could be realized. After closing the Outer Culvert, the turbine would be activated. In particular, there were two groups of such living doors. One group was at the front. The fan's ventilation was divided into two parts, the first part was at the front, and the second part was at the back. The high-pressure exhaust was divided into two parts, and the second part was the Outer Culvert.
This kind of thing. The design to transform the engine is obviously more advanced, this way, at a low speed, the engine would be a Turbofan Engine. It could provide a lot of power. When it was at high speed, when the Outer Culvert was closed, it would be the Turbojet Engine. At this time, the area would be smaller with the wind. It was easy to sprint and fly. What was more ingenious was that this engine could smoothly transition between the turbine jet state and the turbine state. At the subsonic speed, the characteristics of the turbine fan were easy to deal with, and the high-speed characteristics of the turbine at supersonic speed could be said to be... This engine also reflected the technological strength of Y Country.
Unfortunately, it was precisely because it was too advanced and too sci-fi that the Y Country Air Force gave up on this engine in order to avoid failure.
Of course, it was not really giving up. It was just that it was not used on their fourth generation. And this engine was still being funded for research and development. After all, they had suffered a lot of hardships and no longer wanted PFC to monopolize power. The nightmare of the F-15 Queen is still fresh in my mind. So, this new engine, they are also funding it... When they developed the F-35, this new engine suddenly became YF136. The competition with YF135 ended in failure again, all the way until this failure. This type of engine was finally abandoned for research and development.
At this time, this type of engine was no longer just a simple cycle. It had also entered a level of adaptation. In addition to the cycle between the turbine jet and the turbine fan, it had also taken a step forward in adapting to the working environment.
Now, when General Lin mentioned this news, in Qin Guan's mind, it was also a flash of inspiration. The J58 engine that the other party had given him was just a primer. If he used other engine technologies, such as YF120, or even YF136 technologies, he would be able to digest and absorb them. Would it be able to greatly promote the development of his own aerospace power system?
If it really succeeded, then China's aviation technology would be able to look down on the world's standards.
