Chapter 608 Breaking through the speed of sound

Not to mention, when Yang Jing sat in the back seat of the cabin, his heart beat wildly for no reason.Excitement and tension, that is a must.

"Boss, don't worry, I have everything to do with me. I will take you to the sky with all my heart and soul, and then bring you back safely." George, who was sitting in the front seat, turned his head and said to Yang Jing with a smile, "You don't have to do anything else, just do the points I told you just now, and I'll make sure you're fine. Remember, seat belts, oxygen masks, as long as these two things are fine, you're in heaven It's absolutely fine."

Yang Jing squeezed out a smile and gave George a thumbs up.

When the matter came to an end, Yang Jing realized that he was not as calm as he had imagined. It seemed that his character training was not enough.

All the people in the hangar left the hangar, George started the engine, and then the plane slowly drove out of the hangar.

"Radio test, Nest Three, Nest Three, this is Flying Fox One, this is Flying Fox One, please calibrate the radio."

Yang Jing didn't make a sound, but after a burst of current interference in the built-in radio headset in the helmet, another clear voice rang out, "This is Nest No. [-], a radio calibration request has been received, Flying Fox No. [-], your signal is very normal And clear."

"Thank you. The Flying Fox One has slid out, please give instructions to the Nest Three."

"Flying Fox One, please taxi to 24L and wait for the takeoff order."

As soon as the command from the control tower was issued, Yang Jing only felt the fuselage shake, and the plane began to accelerate slowly on the taxiing runway, and then taxied towards the take-off runway.

A few minutes later, the plane came to a solid stop at the end of the takeoff runway, and George's voice sounded again: "Nest No. [-], Flying Fox No. [-] is ready, please take off."

"Received, Flying Fox 40, you can take off in [-] seconds. In addition, the visibility is very good today, and there will be an eight-knot crosswind when you take off. Please pay attention to the crosswind. Flying Fox [-], Nest [-] wishes you The flight was successful today."

"Thank you."

After the call was over, Yang Jing felt the sound of the engine behind him getting stronger and stronger. Obviously, the aircraft engine was increasing its output power.

When the time came, Yang Jing felt a violent push back, as if his body was firmly held down by an invisible big hand.At this time, Yang Jing could clearly distinguish the gap between fighter jets and commercial airliners.

Although ordinary civil aviation airliners also have an obvious push back feeling when taking off, it is far from comparable to the push back feeling produced by fighter jets when taking off, and the two are not on the same level at all.

In the normal fuel loading mode, the F15 only needs a short distance of 500 meters to take off, and if it is in the interception mode, that is, with less fuel, it can even take off in only 300 meters.

Therefore, when the F15 takes off, the acceleration overload the pilot bears is very large, which is why there is such a strong sense of pushing back.

Almost in less than ten seconds, Yang Jing felt his body sinking suddenly, and the next moment, everything on the ground began to move away from him quickly, as if he was riding on a roller coaster, quickly began to rise.

The climb speed of fighter jets is unmatched by civil aviation airliners. The limit climb speed of this thing is as high as 254 m/s. That is to say, under extreme conditions, F15 can quickly rise from the ground to Higher than Mount Everest!

Of course, George would not adopt such a limit climbing speed when Yang Jing took a fighter jet for the first time. After all, Yang Jin needed a process of adaptation.But even so, the climbing speed of F15D still gave Yang Jing a jump.Before Yang Jing even recovered from the sudden overweight feeling, he found that the plane had been flying steadily at an altitude of more than 2000 meters.

Don't ask Yang Jing how he knows the current altitude of the plane, it's very simple, the back seat he is sitting on has an altimeter display
The plane quickly entered a stable flight state, and at this time, looking down and around from an altitude of 2000 meters, it was all blue water. Guam, which was originally thought to be very spacious, completely surrendered to me at this time .

Looking at it from this height, Yang Jing immediately thought of a classic internet idiom - ah, the sea, your fucking sister is all water!
To be honest, I couldn't feel the true artistic conception of this sentence at all before, but today I am flying on the F15D above the sea, and the truest artistic conception of this sentence can be fully reflected.

And as the F15D continued to accelerate and fly to the east, after Guam gradually disappeared, the surrounding area really became the same color as the water and the sky!The sky is blue, and the Pacific Ocean below is also blue. If you look at it everywhere, you can't see other colors except this clear and intoxicating blue.

In fact, this is a kind of extreme purity!In this pure blue, Yang Jing couldn't even feel that he was riding a fighter jet and was flying at a speed close to the speed of sound. He only felt that he was suspended in mid-air. That feeling was wonderful.

But George's voice broke this feeling, "Boss, do you think your body is okay? I mean, at this speed, you don't feel any discomfort, right?"

Yang Jing shook his head subconsciously, and then realized that George sitting in the front seat couldn't see him at all, so he said, "No problem, I don't feel any discomfort at this speed."

George smiled and made a thumbs up from the top of his head, "Boss, your physical fitness really surprised me. Now our speed is Mach 0.9, which is 1080 km/h. Now you are facing the earth in the air The moving speed has exceeded 300 m/s."

"Wow, so fast? But I can't feel it." Yang Jing is telling the truth. In this environment, there is no reference around him, even if he is flying at a speed of Mach [-], he can't feel it.

However, Yang Jing could still see that certain parts of the wing would produce some obvious local shock waves from time to time. Yang Jing knew this phenomenon. This was because although the overall speed of the plane had not yet reached the speed of sound, the plane's The speed has reached Mach 0.9, so the airflow in some parts of the aircraft has actually reached the speed of sound, and this will produce this local shock wave phenomenon.

This is still the case that the current flying altitude of the aircraft is only 2000 meters. If the aircraft is now at an altitude of 1000 meters, the speed of 1080 kilometers per hour has actually exceeded the speed of sound.Because at an altitude of 1000 meters, the speed of sound is only 1066 km/h, far lower than the speed of 1224 km/h at sea level.
The higher you go, the easier it is to break the sound barrier.

"Hehe, do you want to speed up? The limit speed of this aircraft can reach Mach 2.5, but I have never flown at such a fast speed, but I used to fly Mach [-] quite often."

"Okay, speed up, let me feel the thrill of supersonic speed!"

"OK!" After George finished speaking, he began to push the power putter. Yang Jing only felt a bigger push back feeling coming instantly.

Even if there is no reference object, Yang Jing can still feel that the plane is accelerating, especially the roar of the engine behind him is getting louder, and the originally transparent air behind the wing can clearly see the flow of airflow at this time .

Even though Yang Jing was sitting in the sealed cabin at this time, he seemed to be able to feel that the fuselage was under great pressure at this time.

In fact, breaking the sound barrier is not a good thing.When the aircraft is close to the speed of sound, due to the generation of local shock waves at the front of the aircraft flying at high speed, the air is compressed and the resistance increases sharply.At this time, every part of the plane and even the controls reacted strangely, and a slight mishandling would cause the plane to crash.

Therefore, although supersonic flight is a thrill that makes the pilot's adrenaline soar, it is also quite dangerous.The control is good. If there is a slight problem with the structure or fuselage of the aircraft, the aircraft that is fine at ordinary speeds may disintegrate the moment it breaks through the sound barrier.

Yang Jing once watched a video of a US military F18 "Bumblebee" taking off from an aircraft carrier for a training mission. As a result, it was flying at supersonic speed at low altitude. When a "sonic boom cloud" just formed behind the wing, that The "Bumblebee" suddenly disintegrated in mid-air.The scene was so tragic that the pilot didn't even have time to parachute, so he went to drink tea with God with Aiji.

But now, Yang Jing can clearly see that as the sound of the airflow ejected from the engine is getting louder, a white "sound cone" has appeared in front of the nose, and this sound cone will soon extend to the rear, and finally in the A white "sonic boom cloud" similar in shape to a loudspeaker formed behind the wing.

This kind of sonic boom cloud is because the aircraft compresses the surrounding air at the moment when it crosses the speed of sound, so that the water vapor in the air condenses into a cloud, and finally forms a cone behind the wing with the fuselage as the axis. shaped sonic boom cloud.

However, this kind of sonic boom cloud is not often seen. Only when flying over the sea or when the air humidity is high, can this extremely beautiful sonic boom cloud be produced.

Yang Jing was very lucky today, seeing this extremely rare sonic boom cloud during his first transonic flight.

With the generation of the sonic boom cloud, Yang Jing clearly heard an extremely explosive "bang bang", as if a big firecracker was detonated in his ear, and then everything returned to silence, and the sonic boom cloud outside It disappeared, and the harsh sound of the jet of air flow from the engine just now has completely disappeared. The only sound that can be heard in the entire cabin is the sound of the engine moving.

At this time, the speed of the plane has exceeded the speed of sound, so all the sounds outside the plane are inaudible.
