Chapter 2033: Aurora

Now, there are not many things that Qin Guan can see in the Eagle Country. Moreover, everything can be obtained from the system. Qin Guan wants them now, it is just a cover, even if they give it fakes. As long as there is, it is easy to explain the rapid progress of Han in this field.
And this combined cycle engine is really a blank in the current Han country. After all, the aircraft engine technology of Han country is originally backward. This thing really tests the accumulation ability of the industry the most, and it can develop advanced ones. The engine is completely the reason for the shortcut.
The ordinary engine is like this, the combined cycle engine, this is even more blank, and this kind of engine also has its unique use, this is the ultra-high-speed aircraft.
In low-speed flight, the ordinary turbo engine has strong thrust and significant effect. It is already a good choice. However, with this engine, the fighter can only be propelled to Mach 3 at most, no matter how high the speed is.
In this kind of engine, the blades are compressors at the front and the turbines at the back. However, at super high speeds, the intake air does not need to be compressed. The air directly rushing in is already compressed. The existence of the compressor is instead a kind of resistance. So, the front structure must be removed, leaving only the back part of the combustion chamber.
This simplest engine, called a ramjet, is the simplest and most efficient. However, it cannot be started at low speeds, so the two engines have their own advantages.
Therefore, the aerospace power industry has such a consensus to study an engine and combine all their advantages. At low speed, it is a turbo engine, and at high speed, it is a ramjet. These two engines are combined to perfectly realize the flight from low speed to high speed. This is the combined cycle engine.
In Eagle Country, this engine has been implemented. This is the engine of the SR-71 Blackbird reconnaissance aircraft. This aircraft is a fighter with a speed of Mach 3 corresponding to the MiG 25. However, the limit value of the MiG 25 can fly to 3.2. Mach, you have to risk the engine burning out, and the Blackbird reconnaissance plane can easily exceed Mach 3, or even fly to Mach 4.
Because the MiG-25 is an ordinary turbo engine, and the Blackbird reconnaissance plane uses the most advanced combined cycle engine.
Now, not only the Blackbird, in addition to the Blackbird, another reconnaissance aircraft of the Eagle Country has also appeared in everyone's sight.
Hearing what kind of combined cycle engine Qin Guan said, Pellehak spread his hand: "What is this engine? I don't know."
"You don't know? You definitely don't know the Goddess of Dawn anymore?" Qin Guan asked Pelehake.
When he heard the words of Goddess of Dawn, Pelehak finally became calm. He really couldn't deny it, and he couldn't be sure, because the level of secrecy of this project was so high that even Pelehak If you can't reach it, it was done by Area 51!
It is said that Eagle Country is a democratic and free country, and taxpayers have great power. In fact, they also have many secrets, and this area 51 is one of them.
In this area, you can see from the satellite there is a huge runway, but there is no name here, only a code name, because the number on the military map is 51, hence the name.
Of course, it has many other names, such as what water city, dreamland, box, heaven ranch, etc., but it is hidden here, it is obvious.
This is a nuclear test base, which was originally divided into a restricted area, and even the air force could not enter it. The U-2 reconnaissance plane was originally developed here, and then the development of a new black project was started, but no one knew. There are also frequent mysterious events here, such as sudden pops, and some even say that this is also the base for Eagle Nation to study aliens, and so on.
Pelehak knew that Area 51 was actually the flight test base for Eagle State's classified weapons. Grumman had not developed any classified projects, and it was not possible to enter there. The Goddess of Dawn also flew in Area 51.
The spy shadow of "Aurora" was first exposed in 1985. In a budget plan submitted by the Eagle State Air Force to Congress for review, under the U-2 reconnaissance aircraft improvement project, a sub-project named "Dawn Goddess" appeared, which attracted the attention of the news media.
Eagle Nation used to rely on the U-2's high-altitude flight capability to carry out reconnaissance until it smashed in front of the Sam-2 missile and settled in the sand. After that, it developed the SR-71 Blackbird, which has been in service for a long time. Therefore, its next-generation alternative aircraft is definitely under study.
This is the legendary goddess of dawn.
No one knows that this project only appeared in the fiscal budget of Conquest. Last year, the budget for this project was only 80 million eagle yuan, but this year's budget has risen sharply to 2.2 billion eagle yuan.
This project, codenamed Dawn Goddess, the reporters have sharp eyes, and they quickly unearthed all kinds of inside stories. In their speculation, this is a super-sonic reconnaissance aircraft with a speed of Mach 6!
Since the government did not recognize it, the media named it after the reconnaissance plane's budget, calling it the "Goddess of Dawn".
Now, it is the hottest time for the goddess of dawn, Qin Guan mentioned that Pellehake absolutely cannot deny it. "I'm afraid I have to ask you about this." Pellehak said.
Qin Guan shook his head and stopped talking. Hearing the roar in the sky, Chen Rui had already tested this latest fighter in the sky. But in Qin Guan's heart, he was still thinking about this, the goddess of dawn, a godlike existence.
Just before the disintegration of the bear country in the late 1980s, the media found a lot of evidence. Even from the east coast to the west coast of the Eagle country, they felt a mysterious aircraft. The movement of this aircraft was quite large and huge. Under the impact of sound waves, it not only strongly stimulates the eardrums, but also produces shock waves. Because it is transmitted from the sky, it is called a skyquake. Sincerely, it can make all the observation instruments of the Seismological Bureau receive the signal.
At the same time, after flying over, you can also see sausage-like rope-linked condensed smoke in the sky. These are all evidence of the flight of a new hypersonic vehicle.
According to these evidences, the goddess of Aurora has gradually emerged. This is a super aircraft that can reach 6 times the speed of sound and fly at an altitude of 38,800 meters.
However, after the disintegration of the bear country, this aircraft disappeared. It seems that this is just a legend!
