Chapter 208 Ground Effect of Flying Close to the Ground

Yesterday, after Xiao Ning decided to start the challenge directly the next day.

After deliberation, the Mira Mountain project team finally decided on the start time of the challenge, which was seven o'clock in the morning.

At this time, although there are still two hours before the start of the challenge, everyone is very busy.

Various shooting positions inside and outside the tunnel, debugging of drones for overhead shooting, runway lighting preparations for the take-off of stunt planes outside the tunnel...

It is no exaggeration to say that as long as the staff of the Mira Mountain project team are on site at this moment, they have things to do.

The staff is busy, but Xiao Ning, who is about to challenge, is very free.

To be precise, Xiao Ning and Qian Zhen are very free.

Yes, this time the challenge at Mira Mountain, Qian Zhen followed again.

However, it may be because he had been trained enough by the plateau environment in Zheduo Mountain before. After coming to Mira Mountain, which is also scary in altitude, Qian Zhen did not have too obvious altitude sickness.

At this moment, it is located 200 meters away from the entrance of the Mira Mountain Tunnel.

Qian Zhen took a bucket of instant noodles from a few staff members at a distance, and then walked quickly to Xiao Ning's place, which was more than ten meters away, and smiled as he handed the instant noodles to the other party: "Here is the chicken soup." Heck!"

Xiao Ning took the instant noodles and looked at Qian Zhen suspiciously: "Senior Brother Qian, how do you know that I like the instant noodles taste of stewed chicken noodles with mushrooms."

Qian Zhen said casually: "I ate instant noodles with Liu Weiwei in your studio office a while ago, and she told me by accident."

Xiao Ning nodded, then asked while driving: "Aren't you going to eat?"

Qian Zhen shook his head: "I'm afraid that watching your performance later will make me sick, so I'll just eat this."

After Qian Zhen finished speaking, he took out a portable oxygen bottle and took a breath in front of Xiao Ning.

"Didn't you say yesterday that you didn't have any high-reaction feeling this time? Are you still smoking?"

"Just in case..."

Xiao Ning chatted with Qian Zhen while eating.

When the bucket of instant noodles for breakfast was almost eaten, several staff members of the Mirashan project team came over.

In the next few minutes, the staff began to assist Xiao Ning in putting on the full-body protective gear.

After a staff member installed a camera on the Red Bull helmet Xiao Ning was wearing, all the protective gear was put on.

"Don't worry, the live broadcast will start in about 5 minutes. Then you can say hello to the audience and chat for a while. I just asked. The road section on the 'runway' used for planes to take off has not been fully prepared yet."

A staff member left after saying this, and then Xiao Ning was patted on the shoulder by Qian Zhen who was beside him.

"Junior Brother Xiao, I suddenly have something to ask."

"You ask."

"You said that they gave you full armor and this kind of protective clothing for competition and this kind of helmet. Is it really useful?"

Seeing Qian Zhen staring at his outfit, Xiao Ning thought for a moment, then shook his head: "If you mean that these things can protect my safety after the challenge starts, I think it should be useless. "

"Then why do they still give you such a lot of clothes that are not heavy?"

"Didn't you notice that the Austrian Red Bull logo is everywhere on the pants and helmet?"

Feeling like he was acting a little stupid in front of Xiao Ning, Qian Zhen fell silent.

Five twenty in the morning.

Red Bull started pushing streams simultaneously in the live broadcast room of each platform.

What is different from Xiao Ning's previous challenge is that after the live broadcast started this time, what the audience saw was not the countdown to the challenge or the staff shooting the scene from a third perspective.

After the live broadcast started this time, what everyone directly saw was Xiao Ning who was pointing the camera at him.

Because Red Bull has announced the approximate start time of the live broadcast on the Internet in advance, there are already many viewers waiting in the live broadcast rooms of various platforms at this time.

And when everyone found out that Xiao Ning was directly on camera at the beginning of this live broadcast, the number of viewers increased faster than the previous live broadcasts.

Even though it's not yet six o'clock in the morning, the bullet screens in each live broadcast room are still flying.

"Good guy! I'm direct, good guy! Ning Shen is in charge of the mirror himself!"

"I was afraid of oversleeping, so I set the alarm clock at five o'clock, and waited for forty minutes, which is considered to be the start of the broadcast!"

"Ning Shen, I'm already fully dressed!"

"Ning Shen, when did you learn to fly a plane? Why have you never heard of such a thing?"

"Tell me something, Xiao Ning, you're playing more and more abstractly now, you're flying a plane through a tunnel, right?"

"Don't worry, I understand the truth, why do you have to do this challenge early in the morning?"

"Relax! Is that blue plane behind you the one you want to fly?"

After taking a rough look at the barrage, and selectively replying to a few, Xiao Ning pointed the live broadcast camera at the blue plane not far behind him.

"This aircraft is indeed the aircraft used in today's challenge. Its model is Zivko Edge 520 V2, and its power has been upgraded and tuned by the professional team of Red Bull."

"In many aerobatic demonstrations or competitions, this aircraft is often seen."

"If you are interested in this aircraft, you can check the general parameters directly on the Internet."

In the live broadcast screen, the blue plane was parked on the middle line of the road. Except that the paint surface of the whole body was reflecting light under the illumination of the surrounding light sources, it was not far in front of the plane at this time. It was built by the Red Bull team to guide the direction of the plane. The light strips were all turned on at the same time by the staff.

After such a picture was presented in each live broadcast room, the refresh rate of the barrage instantly increased.

"Red Bull's team is still professional!"

"Just by looking at it, there is a feeling that something big is going to happen."

"I checked the general situation of the plane just now. There is nothing else to say. There is one thing...it seems a little scary."

"what's up?"

"Although the plane doesn't look big in the live broadcast, its wingspan is quite wide. I checked the width of the Mira Mountain Tunnel, and roughly calculated it. If the plane flies into the Mira Mountain Tunnel and just If it is located in the middle of the tunnel, the distance between its two wings and the walls on both sides of the tunnel is only about four meters! Then there is the height, if the plane flies in the middle of the tunnel, the distance between the two sides is less than two meters!"

"???"

"My grass!"

"Is it so outrageous?"

"..."

Because a viewer learned the data of the wingspan of the aircraft and the width of the tunnel, as well as the height of the aircraft and the height of the tunnel, other viewers were shocked by this data at the moment.

Once the plane flies into the Mira Mountain Tunnel, it is almost impossible for the plane to change direction.

The position of the aircraft must always be kept in the middle of the tunnel. If there is a slight deviation, the aircraft will either hit the left and right walls of the tunnel, or hit the top of the tunnel or the road below.

The actual situation is that if the aircraft keeps flying at a low altitude at high speed, it is difficult to achieve no flight path deviation at all.

An airplane flying above the ground is nothing like a car with its tires on the ground.

When the car is running on the ground, you just need to make sure to control the steering wheel so that the car always goes in a straight line.

However, in this state of flying close to the ground, it is not that simple for the aircraft to maintain a stable attitude at all times.

Because when the aircraft is in this state of flying close to the ground, there will actually be a special situation that is usually called ground effect.

The so-called ground effect means that if the aircraft is close enough to the ground, water surface, etc., the pressure difference between the upper and lower sides of the entire aircraft will suddenly increase, and the lift will suddenly increase a lot!

It roughly means that if the aircraft flies in the air away from the ground, the lift generated by the pressure difference between the upper and lower sides can be stabilized.

But if the plane that was originally in the air suddenly gets close to the ground, and the air below has no place to go, then the lift force will suddenly increase!

This sudden increase in lift is terrifying to piloting an airplane.

If no measures are taken, the aircraft flying upwards with increased lift will inevitably hit the top of the tunnel directly above the head.

Therefore, the pilot of the aircraft must control the aircraft at the same time when this situation occurs, so as to maintain the stability of the lift of the aircraft at all times and stabilize the flight altitude.

This process will be accompanied by the entire flight of the aircraft in the tunnel.

This also means that in order to complete this challenge without any accidents, after Xiao Ning flies in later, he must always try his best to stabilize the position of the plane in the tunnel and avoid any deviations as much as possible. shift appears!

Once the operation is slightly wrong, the plane will hit the wall [-]% of the time.

In the live broadcast room at the moment, some viewers are posting barrage to popularize all this with others.

During this process, Xiao Ning has actually been staring at the barrage.

Some of the viewers who watched the live broadcast knew this, and Xiao Ning, who directly clicked the [Aircraft Piloting] skill to the master level, naturally couldn't not know it.

In fact, during the period when Xiao Ning had just upgraded his skills and entered the system simulation learning space, when Xiao Ning was simulating the tunnel flight, the various situations in front of him driving the plane into the wall were staged countless times.

And after having learned enough experience and lessons from the countless plane collisions before, he is no longer worried about what will happen after he really enters the tunnel.

For this challenge, Xiao Ning is still full of confidence on the whole.

The next time was spent in the interaction between Xiao Ning and the audience sentence after sentence.

The audience's questions mainly revolved around the Mira Mountain challenge this time, but during this period, there were also some barrage questions asking about the new song.

Xiao Ning will always answer truthfully when there are bullet chats asking about challenges, but for those bullet chats that ask about new songs, Xiao Ning simply pretends that he has not seen them.

Until the time approached the start of the challenge, when Xiao Ning handed over the handheld live camera equipment to the staff of Red Bull, there were still many bullet screens asking about the new song.

"Take care of yourself! What's going on with the new song!"

"Brother Ning, I've swiped so many posts, you probably pretended not to see them on purpose!"

"Did you people not read the Weibo post that Ning Shen posted before? Be yourself! Don't rush!"

"Ning Shen said on Weibo before that he was writing a new song, and he used 'some' in the description of the new song. It is reasonable to speculate that this time Ning Shen is going to release several songs at once, don't rush it!"

"Please respect Xiao Ning's music fans! This is Red Bull's live broadcast room! We can only talk about extreme sports, understand?"

"Sun, there are still 5 minutes until seven o'clock! I don't know if Ning Shen is in a panic, but I am really panicked!"

"My buddy is also panicking! The size of the plane is compared with the size of the tunnel, and it almost has to pass through the tunnel. If it is wiped out in an instant, it will be fine. The key point is that the tunnel is 700 meters long!"

"Take a deep breath everyone!"

"Only 3 minutes left!"

"1 minutes left!"

"Start now!"

"I can't take it anymore! 30 seconds left to start! I have to go lead a shot!"

"Are you really talented? 30 seconds is enough to guide?"

"Don't worry about flying the plane, why don't you just let it fly? I'm stupid!"

"..."

When the bullet screen is being refreshed crazily.

In the live broadcast room of each major platform, in the live broadcast screen shot by the drone, at the starting point hundreds of meters outside the entrance of the Mila Mountain Tunnel, the ground staff around the blue stunt plane have dispersed.

The plane's engine has been started and the propeller is spinning at high speed.

Inside the airplane cabin, under the transparent windshield, Xiao Ning looked ahead with a relaxed expression.

The Red Bull team of the Mira Mountain project team has completed all preparations and inspections. In fact, Xiao Ning had already boarded the plane for inspection in advance when the plane was just delivered to Mira Mountain yesterday.

Now that everything is ready, he can naturally face everything with a more relaxed attitude.

The last 30-second countdown from the staff came from my ear.

Xiao Ning's mind flashed through the process that he had repeatedly rehearsed in the system simulation learning space before, and his gaze was fixed on the entrance of the tunnel that was hundreds of meters away because of the distance.

"three."

"two."

"one."

The countdown for Red Bull staff is over.

At the same time, Xiao Ning, who glanced at the instrument, directly operated the plane to drive out along the middle of the road where Red Bull had already arranged white guide light bars in front.

As the engine speed increases, the speed of the aircraft on the ground also increases.

30KM/H.

40KM/H.

50KM/H.

After reaching the take-off speed, Xiao Ning operated the elevator and pulled the Zivko Edge 520 V2 off the ground effortlessly!
The roar of the huge engine resounded around the Mira Mountain Tunnel, and it also filled the ears of all the audience in the live broadcast room.

in the live screen.

As soon as the blue plane left the ground, a large amount of white smoke began to emit from the tail.

As the white smoke from the tail of the plane elongated, the entrance of the Mira Mountain Tunnel, which seemed far ahead, was only a short distance away in a very short time.

When they were about to enter the tunnel, all the on-site team of the Mirashan project team and the audience in the live broadcast room held their breath together.

There was a whistling sound.

The nose of the blue stunt plane has rushed into the entrance of the Mira Mountain Tunnel!
