Super Weapon Swap System

Now, there are not many things in the eagle kingdom that Qin Guan can see. Moreover, everything can be obtained from the system. Qin Guan wants from them now, which is just a cover. Even if what they give is false, as long as they have it, it is easy to explain the rapid progress of Han in this field.

This combined cycle engine is really a blank in the current Han country. After all, the aeroengine technology in the Han country is originally backward. This thing really tests the industrial accumulation ability. The reason why we can develop advanced engines is that we have taken a shortcut.

Ordinary engines are like this. Combined cycle engines are even more blank, and this kind of engine also has its unique use, which is ultra-high speed aircraft.

In low-speed flight, the ordinary turbine engine has strong thrust and remarkable effect, which is already a good choice. However, relying on this engine, the fighter can only be pushed to Mach 3 at most. No matter how high the speed is.

The front of this engine is a blade, which is a compressor, and the back is a turbine. At ultra-high speed, the intake air does not need to be compressed, and the air directly rushed in has been compressed. The existence of the compressor has become a resistance. Therefore, the front structures should be removed, leaving only the rear combustion chamber.

This simplest engine, called the ramjet, is the simplest and most efficient. However, it cannot be started at low speed, so the two engines have their own advantages.

Therefore, the aviation power industry has a consensus to study an engine and integrate all their advantages. In the case of low speed, it is a turbine engine and in the case of high speed, it is a ramjet. Combine the two engines to perfectly realize the flight from low speed to high speed, which is the combined cycle engine.

In Eagle country, this kind of engine has been realized. This is the engine of SR-71 blackbird reconnaissance aircraft. This aircraft is a fighter with a speed of Mach 3 corresponding to MIG 25. However, the limit value of MIG 25 can fly to Mach 3.2, and the risk of engine burn-out. However, blackbird reconnaissance aircraft can easily exceed Mach 3 or even Mach 4.

Because the MiG-25 is an ordinary turbine engine, while the blackbird reconnaissance aircraft uses the most advanced combined cycle engine.

Now, not only the blackbird, but also another reconnaissance aircraft of Eagle country has appeared in everyone's sight.

Hearing what Qin Guan said about the combined cycle engine, pelehak spread his hand: "what is this engine? I don't know."

"Don't you know? You certainly don't know the goddess of dawn?" Qin Guan asked pelehak.

When he heard the words of the goddess of dawn, pelehak was finally not calm. He really couldn't deny or affirm it, because the confidentiality level of this project was so high that pelehak couldn't even touch it. It was done in Area 51!

It is said that Eagle country is a democratic and free country, and taxpayers have great power. In fact, people also have many secrets, and this area 51 is one of them.

In this area, you can see a huge runway from the satellite, but there is no name here, only the code, because the number on the military map is 51, so it is named.

Of course, it has many other names, such as water city, dream, box, Paradise ranch and so on. However, it is hidden here, which is obvious.

This is the nuclear test base. At first, it was divided into restricted areas, and even the air force could not enter. At first, the U-2 reconnaissance aircraft was developed here, and then the research and development of new black projects began. However, no one knows that mysterious events and sudden explosions often occur here. Some people even say that this is also the base for Eagle country to study aliens, and so on.

Pelehak knows that zone 51 is actually a test flight base for eagle's confidential weapons. Grumman company has not developed any confidential projects and has no chance to enter there. The goddess of dawn also tested in zone 51.

The spy shadow of "dawn goddess" was first exposed in 1985. In a budget plan submitted by the Eagle Air Force to Congress for review, a sub project named "goddess of dawn" appeared under the improvement project of the U-2 reconnaissance aircraft, which attracted the attention of the news media.

Eagle used to rely on the U-2's high-altitude flight ability to carry out investigation until it lost its halberd in front of the sam-2 missile. Later, it developed the SR-71 blackbird, which has been in service for a long time. Therefore, its next generation of alternative aircraft must be under research.

This is the legendary goddess of dawn.

No one knows that this project only appeared in the financial budget of conquest. Last year, the budget of this project was only 80 million Eagle yuan, but this year, the budget has increased sharply to 2.2 billion Eagle yuan.

This project, code named the goddess of dawn, the reporter's eyes are bright. They soon dug out all kinds of secrets. In their speculation, this is an ultra-high speed reconnaissance aircraft, with a speed of Mach 6!

Since the government does not recognize it, the media will name the reconnaissance plane after its budget and call it the "goddess of dawn".

Now, it is the hottest time for the goddess of dawn to quarrel. When Qin Guan mentioned it, pelehak can't deny it. "Well, I'm afraid I have to ask you," said pelehack.

Qin Guan shook his head and stopped talking. Listening to the roar in the sky, Chen Rui has tested this latest fighter in the sky. In Qin Guan's heart, he was still thinking about it. The goddess of dawn, the existence of God.

In the late 1980s, just before the disintegration of the Bear Kingdom, the media found a lot of evidence. Even from the east coast to the west coast of the eagle Kingdom, they felt a mysterious aircraft. The movement of this aircraft was quite large. Under the impact of huge sound waves, it not only strongly stimulated the eardrum, but also produced seismic waves. Because it came from the sky, it was called a celestial earthquake, Sincerity can make the Seismological Bureau's observation instruments receive signals.

At the same time, after flying, you can also see the sausage like rope end smoke in the sky, which are the evidence of a new hypersonic vehicle.

According to these evidences, the goddess of dawn also gradually emerged. It is a super aircraft that can reach six times the speed of sound and fly at an altitude of 38800 meters.

However, after the disintegration of the Bear Kingdom, this kind of aircraft disappeared. It seems that this is just a legend!
