From Signing In To Dominate The World

"Dr. Herbert, we made it!"

Dawn No. 1 successfully took off and screamed into the blue sky at an incredible speed.

All the staff looked up excitedly and rejoiced.

Herbert was not eager to be happy, but stared at the soaring Dawn One.

Taking off does not mean success.

The most important thing is how the aircraft reacts when the speed reaches its limit.

Cameron drove Dawn No. 1 and continued to accelerate, and soon, the sound barrier appeared as expected.

When the flight speed reaches nine tenths of the speed of sound, that is, when the air speed is about 950 kilometers per hour, the speed of the local airflow may reach the speed of sound, generating a local shock wave, which causes a sharp increase in aerodynamic drag.

To further increase the speed, the engine needs more thrust. What's more serious is that the shock wave can make the air flow through the wings and the surface of the fuselage become very turbulent, which makes the aircraft shake violently and make it difficult to control.

At the same time, the wings will sink and the nose will drop. If the aircraft is climbing at this time, the fuselage will suddenly automatically rise. These symptoms may cause the plane to crash, which is the so-called "sound barrier" problem.

Since the transmission speed of sound waves is limited, the moving sound source can catch up with the sound waves it emits. When the speed of the object increases to the same as the speed of sound, sound waves begin to accumulate in front of the object. If the object has sufficient acceleration, it can break through the unstable sound wave barrier and rush to the front of the sound, that is, break the sound barrier.

An object moving at supersonic speed will continue to produce a stable pressure wave in front of it. When the object is moving towards the observer, the observer will not hear the sound; after the object passes, the generated wave will be transmitted towards the ground. The pressure difference will have an audible effect, which is a sonic boom.

When the flying speed of an aircraft is lower than the speed of sound, the air in contact with the aircraft acts like a "communication officer", "notifying" the air that is about to encounter the aircraft ahead at the speed of transmitting the sound, making them "gave way."

But when the speed of the airplane exceeds the speed of sound, the air in front of the airplane is tightly compressed because it is too late to escape, and gathers into a thin wave surface-shock wave. Behind the shock wave, the air is compressed and the pressure suddenly rises. High, preventing further acceleration of the aircraft, and may cause the wing and tail to vibrate violently and explode.

The sound barrier is not only the sound wave, but also the resistance from the air. When the flying object is flying close to Mach 1, which is the speed of sound, the air rushing forward cannot spread through the fuselage as usual, so the gas is accumulated. The extreme pressure generated around the flying body will also cause an invisible air vortex, commonly known as the "death vortex". If the fuselage is not specially reinforced, it will be shaken to pieces in an instant!

Now, there is a "death vortex" around the fuselage of Dawn 1, and its speed has reached the critical point of breaking through the speed of sound!

And Dawn No. 1 is destined to be a supersonic fighter!

Herbert kept his eyes closed, holding his breath.

Success or failure is at this moment!

"boom!"

After the loud noise, the whole world fell silent.

Breaking Dawn No. 1 successfully broke through the speed of sound, that is, through the sound barrier!

At this time, the pressure around the fighter jet will drop sharply. The instantaneous low temperature caused by the sharp drop pressure will make the high-pressure air fall below its dew point, causing the water vapor to condense into tiny droplets, which look like clouds to the naked eye. state.

Since this low-pressure zone will return to normal pressure as the distance between the air and the fuselage increases, the overall shape looks like a cone-shaped cloud with the object as the central axis and uniformly spreading around.

The whole process seemed thrilling, but in fact it was only a short ten seconds.

Soon, Dawn No. 1 disappeared into the sky, without a trace.

Herbert breathed a sigh of relief and smiled.

The speed of Dawn 1 can reach Mach 1.3.

Mach number is the ratio of speed to sound speed. The speed of sound has different values ​​at different altitudes, temperatures, and atmospheric density, but it is just a relative value. The Mach number 1 is double the speed of sound, which is equal to 340ms, which is 1224 kilometers per hour. The Mach number is less than 1 is subsonic, and greater than 1 is supersonic.

The B2 bomber had a speed of Mach 0.95, which failed to break the speed of sound.

The speed of sound and supersonic speed may seem to be only a small difference in value, but in fact it is an epoch-making improvement!

This is Chen Liang’s first flight in a fighter plane, and he is also a supersonic fighter.

When Dawn One broke through the speed of sound just now, and the environment changed from extremely dynamic to extremely quiet, the feeling was indescribable.

If you really want to describe it, it's like "traversing", they seem to have broken through the shackles of the rules of heaven and earth, and entered another space from one space.

Einstein once said that when the speed exceeds the speed of light, one can transcend time and even reverse time and space.

Chen Liang could feel this feeling slightly now.

The speed of the high-speed rail is generally 200-250 kilometers per hour, and his current speed is almost seven times that of the high-speed rail!

"Mr. Chen, in the next 100 years, there may be no better fighter than Dawn."

Even if you know the various values ​​of this fighter in advance, but when you control it immersively, Carmine deeply feels its charm.

You know, this is not a fighter plane known for its speed, but a bomber!

Carmine's implication is undoubtedly that Dawn can lead the world for a hundred years, which may be a bit exaggerated, but it is enough to prove the shock that Dawn has brought him.

"How long will it take to enter America's airspace?"

Chen Liang asked.

"In fact, we are now in America's airspace."

Carmine responded, a strange emotion in the slightly trembling voice.

America, recognized as the world's No. 1 military power, can anyone in the world enter its territory without being allowed?

But now he did it.

And the Americans didn't even notice it.

Only then did Chen Liang realize that the Bahamas are already closer to America. Although they have not yet entered America, they may have entered America's territorial waters unknowingly because of the terrifying speed of dawn.

In the past, only America relied on its strong military strength to send fleets or planes to other people's homes from time to time. The arrogant Americans should never have thought that one day someone else would break into their homes silently.

"Mr. Chen, the southeast gate of America is in front of you, Florida."

Carmine reminded.

Although he also had some kind of impulse in his heart, it was not a trivial matter after all.

You know, armed crossing without permission, even if it's just an airplane, a soldier, or a battleship, that is equivalent to aggression!

"Fly in."

Chen Liangruo's nonchalant response came.
