Not to mention, when Yang Jing sat in the back seat of the cabin, his heart beat a few times for no reason.Excitement and nervousness, that's a must."
Boss, don't worry, everything is with me, I will take you to the sky happily, 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 will guarantee that you are okay."
Remember, seat belts, oxygen masks, as long as these two things are okay, then you are absolutely fine in heaven. ”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 imagined, and it seemed that this character exercise was still not enough.The people in the hangar all left the hangar, George started the engine, and the plane slowly drove out of the hangar."
Radio test, Nest Three, Nest Three, this is Flying Fox One, here is Flying Fox One, please calibrate the radio."
Yang Jing didn't squeak, but after a burst of electrical interference, another clear voice sounded, "This is Nest No. 3, I received a radio calibration request, Flying Fox No. 1, your signal is very normal and clear." ”"Thank you.Flying Fox One has slipped out, ask Nest Three to give instructions. ”"Flying Fox One, please taxi to 24L and wait for take-off orders."
As soon as this order from the tower was issued, Yang Jing only felt a shock to the fuselage, and the plane began to slowly accelerate 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 take-off runway, and George's voice sounded again: "Lair Three, Flying Fox One is ready, please take off." ”"Roger, Flying Fox One, ready to take off in forty seconds.Also, the visibility is good today, and it is estimated that there will be a crosswind of eight knots during takeoff, so please be aware of the crosswind.Flying Fox One, Nest Three wishes you a successful flight today. ”"Thank you."
After the call, Yang Jing felt that the engine behind him was making a stronger and stronger sound, and it was obvious that the aircraft engine was increasing its output power.As soon as the time came, Yang Jing felt a violent push on his back, as if his body was slammed by an invisible hand.At this time, Yang Jing was able to clearly distinguish the gap between fighter jets and civil airliners.Ordinary civil airliners also have an obvious sense of pushing back when taking off, but they are far from being able to compare with the feeling of pushing back when a fighter takes off, and the two are not on the same level at all.The F15 only needs a short 500 meters to take off in normal fuel-carrying mode, and even only 300 meters to take off in interception mode, that is, with a small amount of fuel.Therefore, when the F15 takes off, the pilot is subjected to a large acceleration overload, which is why there is such a strong sense of pushing back.Almost in less than ten seconds, Yang Jing felt his body sink suddenly, and the next moment, everything on the ground began to quickly move away from him, as if he was riding on a roller coaster, and quickly began to rise.The climb speed of the fighter jet is incomparable to that of a civil airliner, and the ultimate climb speed of this thing is as high as 254 meters per second, that is, in extreme situations, the F15 only needs a little more than 34 seconds to quickly rise from the ground to a height exceeding Mount Everest!
Of course, George would not have used such a limit climb speed when Yang Jing took a fighter for the first time, after all, Yang Jin needed a process of adaptation.But even so, the climbing speed of the F15D also gave Yang Jing a jump.Before Yang Jing could even recover from the sudden feeling of being overweight, he found that the plane had been flying steadily at an altitude of more than 2,000 meters.Don't ask Yang Jing how he knows the altitude of the plane now, it's very simple, the back seat he was riding in, there was an altimeter that showed that the plane quickly entered a stable flight state, and at this time, looking down and around from a height of two thousand meters, it was all blue water, and Guam, which originally felt very wide, was completely surrendered to him at this time.Looking at it from this height, Yang Jing immediately remembered a classic Internet phrase - ah, the sea, your sister is all water!
To be honest, I couldn't feel the true artistic conception of this sentence before, but today I am flying above the sea on the F15D, and the most real artistic conception of this sentence can be most thoroughly reflected.And as the F15D continues to accelerate to the east, Guam gradually disappears, and the surrounding area is really a color of water and sky!
The sky is blue, and so is the Pacific Ocean below, and everywhere you look, you can't see any other color than this clear and intoxicating blue.In fact, this is the ultimate purity!
In this pure blue, Yang Jing couldn't even feel that he was flying in a fighter plane and flying at a speed close to the speed of sound, he only felt as if he was suspended in mid-air, and that feeling was wonderful.But George's voice broke the feeling, "Boss, do you think your body is fine?"
I mean, you don't feel any discomfort at this speed, do you?
”Yang Jing subconsciously shook his head, and then realized that George, who was 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 gestured a thumbs-up from the top of his head, "Boss, I'm really surprised by your physical fitness.Now our speed is Mach 09, which is 1080 kilometers per hour, and now you are moving in the air relative to the Earth at a speed of more than 300 meters per second. ”"Wow, so fast?
I can't feel it, though. ”Yang Jing is also telling the truth, in this environment, there is no reference around, even if the speed of flying ten Mach is now, it is not perceptible.However, Yang Jing can still see that some parts of the wing will produce some obvious local shock waves from time to time, this phenomenon Yang Jing knows, this is because although the overall speed of the aircraft has not yet reached the speed of sound, but the speed of the aircraft has reached Mach 09, so the airflow in some parts of the aircraft has actually reached the speed of sound, which will produce this phenomenon of local shock waves.This is still the case when the flight altitude of the plane is only 2,000 meters, and if the plane is at an altitude of 11,000 meters, the speed of 1,080 kilometers per hour has actually exceeded the speed of sound.Because at an altitude of 11,000 meters, the speed of sound is only 1,066 kilometers per hour, which is far lower than the speed of 1,224 kilometers at sea level."
Hehe, do you want to speed up?
The plane can reach a maximum speed of Mach 25, but I've never flown that fast, but I've always flown Mach 2 before. ”"Okay, you speed up, let me feel the thrill of supersound!"
“ok！”
After George finished speaking, he began to push the power pusher, and Yang Jing only felt that a more huge push back feeling came instantly.Even if there was no reference, Yang Jing could feel that the plane was accelerating, especially the roar of the engine behind him was getting louder and louder, and the originally transparent air behind the wing could clearly see the flow of air flow at this time.Even if 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, in the front of the aircraft flying at high speed, the air is compressed due to the generation of local shock waves, and the drag increases sharply.At this time, all parts of the plane and even the control have a strange reaction, and the slightest improper disposal will destroy the plane and kill people.Therefore, supersonic flight is certainly an adrenaline thrill for pilots, but it is also quite dangerous.If there is a slight problem with the structure or fuselage of the aircraft, then 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 F18 "Hornet" taking off from an aircraft carrier for a training mission, but it flew at supersonic speed at low altitude, and when a "sonic boom cloud" had just formed behind the wings, the "Hornet" suddenly disintegrated in mid-air.The scene was so tragic that the pilot didn't even have time to parachute, so he went to God for tea with his love plane.Now, Yang Jing can clearly see that as the sound of the air jetting out of the engine is getting louder and louder, a white "sonic cone" has appeared in front of the nose, and this sonic cone soon extends to the rear, and finally forms a white "sonic boom cloud" similar to the shape of a big horn behind the wing.This sonic boom cloud is because the plane compresses the surrounding air because it is too fast at the moment it crosses the speed of sound, so that the water vapor in the air condenses into a cloud, and eventually forms a cone-shaped sonic boom cloud behind the wing with the fuselage as the axis.However, this kind of sonic boom cloud is not often seen, and it is only possible to produce this extremely beautiful sonic boom cloud when flying on the sea surface or when the air is very humid.Today, Yang Jing was lucky to see this extremely rare sonic boom cloud for the first time in a transonic flight.With the generation of the sonic boom cloud, Yang Jing clearly heard an extremely explosive "pop" sound, as if a big explosion was detonated in his ears, and then, everything returned to silence, the sonic boom cloud outside disappeared, and there was some harsh engine jet sound just now, which was completely disappeared at this time, and the only sound that could be heard in the entire cabin was the sound of engine movement.By this time, the speed of the plane had broken through the speed of sound, so all sounds outside the plane were inaudible
