Although the formation of the plane taking off has already tightened the heartstrings of all the audiences at the scene and in each live broadcast room.

But in fact, everyone knows very well that whether it is the huge roar of the engine just now or the large number of bundles of white smoke at the tail of the plane, all this is just the beginning.

This time, Shawning and Red Bull cooperated to cross the Mira Mountain Tunnel, and the focus of its difficulty lies in the entire process of the plane taking off into the tunnel.

Although the whole process is very difficult, the most difficult part is actually the process when the plane just enters the tunnel and finally flies out through the tunnel.

Although Xiao Ning and the Red Bull team finally agreed that the challenge time was set in the morning when the temperature difference and air pressure difference between the inside and outside of the tunnel were relatively small, but even so, Xiao Ning, who was controlling the aerobatic plane, still had to face the air pressure change when the plane just entered the tunnel.

At this time, the first half of the plane had just entered the tunnel, and the staff present and many viewers who got up early in the morning to watch the live broadcast were holding their breath.

The airplane, a product invented at the beginning of the last century, has never changed from the first aircraft built by the brothers to fly into the sky, the "Flyer 1", until now.

The reason why an airplane is able to fly is because the upper and lower parts of the airplane's wings are subjected to different pressures in the air. The air above the wing surface is designed to flow faster and under less pressure, and when the pressure under the wing surface is greater than the pressure above the wing, the aircraft will gain the lift generated by the pressure difference between the two sides and fly upward.

Under normal circumstances, if an aircraft flying outside suddenly enters an enclosed place such as a tunnel and flies almost close to the ground, the additional lift generated by the ground effect will inevitably increase the lift of the aircraft itself.

At this time, when the first half of the aerobatic plane piloted by Xiao Ning had just entered the tunnel, everyone could clearly see that the plane had a slight upward momentum of steep altitude.

If Xiao Ning, as the pilot, did nothing in this situation, then the plane would have crashed directly into the roof of the tunnel due to the extra lift.

What he had to do now was to offset the extra lift by adjusting the wing details with the elevator.

The hardest part is also here.

The reason why modern aircraft can control the ascent and descent is also achieved by changing the attitude of the wings, thereby changing the air velocity on the upper and lower surfaces, and then changing the pressure and lift.

The principle of operating the elevator to offset the excess lift is to make the lift force of the aircraft in its original state smaller, so that the aircraft that originally flew "falls" down.

But how much do you want to "drop"?

The lower the downward amplitude of the operating elevator, the excess lift of the aircraft, which cannot counteract the ground effect, still rises, which will be a crash and death.

If the downward amplitude is a little more, the lift lost by the aircraft includes not only the lift generated by the ground effect but also the force that lifts the aircraft upward, then the lift cannot cancel out the gravity of the aircraft, and it will fall straight to the ground at high speed.

In such a process, especially when flying such a small propeller aerobatic plane with a flexible attitude, it is a very detailed matter to control the elevator reasonably.

It's like using a not-so-thin thread through the eye of the formation, a little up and down is not at all, it must be just right.

The barrages in each live broadcast room had already exploded when Xiao Ning drove the plane to the tunnel.

"Ning Shen is rushing in!"

"Ha people!"

"To be honest, I didn't wake up a little early to watch the live broadcast, but now I do wake up and my pants are wet."

"Didn't there be a ground effect of Brother Science before? It must have started after Ning Shen entered the cave, right? ”

"It's the hardest place to get to grips with that lift balance at first!"

"Take a deep breath and wait for the tranquility to succeed!"

"Don't bump into it!"

"Dude, I really can't breathe now."

"I'm grass! The plane is tilting upwards! ”

"! It's time to start operating! ”

"Like! It seems to be down a little bit again! ”

"Can you hold it down?"

“……”

The most critical step in this challenge was to get the plane into the tunnel and maintain level flight.

The audience in front of the live broadcast room and everyone on the scene were nervous.

At this time, under the incomparably precise operation of Xiao Ning, the aerobatic plane entering the tunnel began to shuttle steadily in the center of the tunnel after the fuselage went up and the operating elevator offset the lift downward due to the ground effect!

IN ADDITION TO THE MAXIMUM SPEED OF 288KM/H, THE MISSION ALSO REQUIRES AN AVERAGE SPEED OF NOT LESS THAN 250KM/H DURING THE ENTIRE TUNNEL JOURNEY!

In order to fulfill these two requirements, Shawning had to run as fast as possible in the tunnel.

After finding the balance point of the elevator operation, he piloted the plane without the slightest hesitation and directly began to accelerate in the tunnel!

It was as if the plane encased in the tunnel was accelerating wildly, and the sound of the engine whistling seemed to detonate the entire tunnel.

"Boom!"

"Boom!"

"Boom, boom!"

Under the shooting of those fixed positions, the bundle of white smoke from the tail of the blue plane flying past these positions has been stretched into a long straight line!

The plane is accelerating wildly with an unstoppable momentum, flying towards the endless front with an altitude of only a few meters and an average distance of only two meters between the top and bottom of the plane!

The people at the scene were already applauding excitedly because Xiao Ning had just managed to control the plane under the ground effect.

At this time, the audience who watched the challenge in each live broadcast room was also completely excited.

Especially when you hear the roar of an aircraft engine in a confined environment like a tunnel!

"That's cool! It's a peace of mind! Worthy of Red Bull! ”

"It's not just about playing with your life! Do you know how hard it was for Ning Shen to do all of this? When you first enter the tunnel, not to mention the operation of overcoming the ground effect, after entering the tunnel completely, the vortex will suck the plane to the ground! If you pull too much, the plane will hit the top! If it is pulled small, it will rush to the ground again! The key is that Thanima is controlled just right! ”

"This horse is even more exciting than a supercar blowing up a tunnel! Bang bang bang! ”

"Ning Shen Zhen Nima is handsome!"

"Oh yes, I'm grass! It's handsome! ”

"Handsome to handsome! But it's still terrifying! The wings on both sides of the Ning Shen are too close to the tunnel wall! ”

"This looks like it's only two or three meters!"

"The speedometer displayed in the live broadcast room should be synchronized with the scene, right? THE CURRENT SPEED HAS REACHED 220KM/H! ”

"You're delayed, aren't you? I LOOK AT THE SPEED HERE AT 265KM/H! ”

"In this high-speed situation, Ning Shen's rudder is slightly off the apex, I'm afraid it will directly hit the walls on both sides!"

"I'll be honest! I don't even dare to fly a plane like this when I play GTA! It's really a lot of people who are bold! ”

"Look! Red Bull's people cut the camera to Ning Shen's face! ”

"I'm grass! I thought that even Ning Shen would be frowning and engrossed at this time! But I don't think he's nervous! That's so unreasonable, isn't it? ”

"I think it makes sense for a titanium heart and a Red Bull with blood vessels flowing throughout the body."

The Red Bull broadcast team cut into the live footage built into the airplane's cabin glass.

In such a high-speed situation, which should have made people nervous, Xiao Ning's face really did not have any performance related to the word "nervous".

And the reason why he can be so calm is naturally not because his heart is made of titanium alloy, and the blood flowing in his body has been replaced with Red Bull.

Previously, after adding points to enter the system simulation learning space, Xiao Ning had rehearsed the same scenario thousands of times.

He has had too many times of nervousness with his legs and stomachs trembling, his hands holding the direction sweating, and his heart beating wildly.

Although Xiao Ning still felt the thrill of flying an airplane through the tunnel at high speed at this time, this stimulation had become extremely limited.

He has practiced so many times that he is almost numb, but he is fully capable of achieving maximum calmness and rationality.

At this moment, Xiao Ning's gaze was firmly fixed on the front, and his afterglow was always fixed on the curved concrete walls on both sides.

In order to ensure that Shawning accurately determines the position at high speeds, the Red Bull team has installed white light bars on the walls on both sides of the tunnel in advance for the purpose of the light bar, which will run through the entire tunnel.

In a confined and similar environment, especially at this high speed, it is difficult for Xiao Ning to completely maintain the accuracy of his flight by relying solely on the tunnel as a reference, and these light bars can help him sense the distance between the plane and the sides.

In the most stable operation possible, the aircraft has always maintained a state of acceleration, and from the beginning to the present, the wings on both sides have been kept within a safe range from the tunnel walls.

Of course, the so-called safety range is actually only three or four meters.

265KM/H！

275KM/H！

285KM/H！

291KM/H！

In the applause of the staff who watched the screen through the monitor at the scene, Xiao Ning had reached the maximum flight speed required for this mission in a short time.

And he didn't mean to slow down when he completed the top speed requirement.

Tunnels are different from the outside world because in this kind of environment, which is equivalent to a confined space, the air flow is naturally worse than that of the outside world.

However, it is not that there is no air flow in the tunnel, but that the air flow is extremely unstable.

In addition to the influence of climate and time, the cause of unstable air flow is also affected by the slope of the tunnel itself.

Yes, the Mira Mountain Tunnel is a road tunnel, and although the tunnel is almost straight throughout, there is a difference between the height and the top.

The road is straight, but the slope is not always consistent.

In such a section of the road with a slightly larger height difference, the air flow or air waves will cause the aircraft to turbulent.

Whether it continues to accelerate or begins to decelerate, it is very likely that the aircraft will lose control to a certain extent due to turbulence in the face of these air waves.

If it was in an external environment with a wide space, any experienced pilot could redeem this level of loss of control.

But it's in a confined and narrow tunnel.

Xiao Ning didn't rashly choose to slow down after reaching the top speed, not because he had a big heart, nor because he was too happy, but because he still maintained enough rationality.

If you want to fly out alive, don't mess with the speed.

In the following process, Xiao Ning, who always maintained a speed of 280 to 290 with only minor changes, continued to steer the plane forward.

Although Xiao Ning, who was wearing a helmet and headphones in the cockpit, could not intuitively feel the wind noise from the outside world, the vibration from the wind hitting the windshield was something he could sense at all times.

"It's been more than half gone."

Xiao Ning, who was firmly in control of the plane, continued to fly with full concentration.

And when he stayed focused, the audience in the live broadcast room was already excited!

"Red Bull is a real cow! If Ning Shen wants to play it, he will really dare to sponsor it! ”

"Suddenly I feel that Ning Shen is not driving an airplane, this state seems to be more like a ground-effect aircraft!"

"Ning Shen used to drive AE86 to more than two hundred in that Autumn Stygian Mountain, and I was already quite shocked, but now Nima is really in the tunnel to keep two hundred and eight at a constant speed!"

"Ning Shen looked at it from the first perspective...... Nima: I really feel like the game screens, I feel like I'm playing a VR flight racing game! ”

"Ning Shen is really stable! Fly so steadily! ”

"Steady? But if you make a corner, do you see if he can be stable? ”

"There are no corners, give a bad review!"

"I don't really understand why Ning Shen wears a helmet, you say that playing like him like this, is it really necessary to wear a helmet?"

"It doesn't matter if you wear a helmet or not, but the Red Bull on the helmet does!"

"Red Bull: Indeed."

“……”

Soon.

Shuttling through the tunnel, the blue planes in the center of the white marker light bar on both sides are only the last bit of road left from the final tunnel exit.

In a few seconds, the plane will burst out of the tunnel and complete the feat of crossing the tunnel that is more than 5,700 meters long!

At this moment, at the other end of the tunnel, hundreds of meters outside the exit, many Red Bull staff members gathered around the monitor.

Some nervously remained silent.

Some people watched the smoothly flying plane in the picture and applauded repeatedly.

Someone excitedly communicated with the colleague next to him.

Chen Qingzheng, who had just finished talking to a staff member, was about to continue looking at the monitor, and when he witnessed the picture of the plane flying out of the tunnel a few seconds later, he suddenly found that Qian Zhen, who was at the edge of the crowd, was looking at the monitor while taking a large gulp of oxygen from the oxygen cylinder in his hand.

Chen Qing hurriedly walked over: "Brother Zhen, what's wrong with you?" Didn't you say that this time the high reaction is not serious? It's high again? ”

Qian Zhen took a sharp breath of oxygen and shook his head repeatedly: "It's not a high anti!" ”

"It's so special, I watched Senior Brother Xiao fly the plane like this, suffocating! I'm suffocating! ”

Chen Qingzheng wanted to speak.

The blue aerobatic plane with the Red Bull logo on the wing and fuselage has already flown out of the tunnel exit, and in a terrifying posture with an inclination angle of almost 90 degrees, it soared into the sky and soared into the sky!

The white smoke from the tail of the plane was stretched into a long strip, as if to remind everyone that it had just completed the crossing of the Mira Mountain tunnel.

In the sky, it was a blue plane that flew high and then slowed down at the corner, and the sunlight reflected a unique metallic luster on the fuselage, and the plane flew smoothly and then turned at an angle, attracting everyone's attention at this time.

No matter who sees such a scene now, they will cheer and applaud from the bottom of their hearts!

The cheers and applause at the scene were thunderous!

In the official live broadcast rooms of each Red Bull, the barrage of "666" has also covered the entire live broadcast screen!

Shawning has completed the feat of flying a plane across Mount Mira!

He's the first person on the planet to do it all!

Qian Zhen's voice sounded beside Chen Qing.

"I feel breathless when I look at it!

"But! How handsome! ”

"My junior brother Xiao is really handsome!"

Increase the amount tomorrow, I don't know how much to add, anyway.

Everyone has a monthly ticket to vote for, look at the plus.
