Chapter 425

As for the three-stage acceleration, it is basically the strengthening of the second-order acceleration.

Due to more magic infusion, it accounts for more than 20% of the power output of the magic tower, and even as high as 80%. The influence area of the wind separation array and the beam wind array in the front and back of the aircraft will reach a frightening degree - two or three hundred meters in the front and five or six hundred meters in the rear.

In this way, the two adjacent areas that exhaust and inhale will naturally form strong air convection. This convection itself will provide a very strong buoyancy and forward power for the aircraft, let alone more excellent effects of reducing drag and improving engine efficiency.

"Continue to infuse energy into the magic array. If it exceeds 20% of the total power of the magic tower, the speed of the aircraft can continue to increase, but the speed of increase will also be slower and slower..." As Fowles explained, he continued to speed up.

At this time, the plane has climbed to a rather frightening height. The air is thin, and the stars in the night sky do not twinkle very much. With the increasing output, the two wings and tail wings of the aircraft have unconsciously condensed several long wake.

The plane is still accelerating, 30%, 28%, 40%, 29%, 60%, 300, 70%

Forrest didn't know about 70% of the situation. From 60% of the time, the plane suddenly began to bump up and down violently, and the whole body was shaking violently, as if it could be scattered at any time.

Although through thousands of magic circles all over the body, the structure of the plane has been basically melted into a whole; although the people in the plane are very human, they are not the weak people who will be desperate and helpless in case of an accident in the air

The violent turbulence still made Fowles stop accelerating, and the control core slowly extracted the energy injected into each magic array.

The sound barrier appears!

When the speed of the flying object approaches 90% of the speed of sound, the sound barrier will begin to appear.

When the body is flying, sound will be emitted from every position. If the object making the sound flies forward at the speed of sound, then the sound wave spreading around will form resonance vibration around the object because it is just at the same speed as the sound, and it will be superimposed layer by layer, and finally Shake the object completely into powder.

In another world, it has been a difficult problem that has plagued the aviation industry for a long time. If you want to break through the sound barrier, you should have two conditions:

first of all, the engine of the aircraft is strong enough and the acceleration is fast enough. The shorter the aircraft stays in the speed zone of sound barrier, the lower the danger will be. It is as if the fighter can obtain the reaction force by hitting the sound barrier at the beginning of douzong level.

This is obviously not available in the magic tower of the airplane. The magnetic engine is naturally weak in this respect. In addition, in the sound barrier area, the resonant sound wave is similar to the fighting roar of the king Dou, which will greatly destroy the array's restriction on the air molecules, and weaken this possibility.

Secondly, the structure of the aircraft should be reasonable enough to meet the aerodynamic standards.

No one knows more about aerodynamics than Fowles, but The world's manufacturing technology, however, can't make accessories that meet that precision. In high-speed flight, the aircraft sends out too much noise from the top to the bottom, and the sound barrier is mainly formed by the sound from the object itself.

Hoo ~ ~ sure enough, it still can't work! Fowles breathed.

Looking at the acceleration of the magic tower of the airplane, if you want to break through the sound barrier, you have to stay in the sound barrier area for at least ten seconds, which is equivalent to exposing the magic tower from the inside to the outside for about ten seconds.

The people inside can't stand it. The array inside and outside the magic tower can't stand it any more. If it can't stand it, it will stop spinning, and then it will stay in the sound barrier area for a longer time

In this way, we can never break through the sound barrier.

The magic tower of the plane has resumed the second level cruise speed of 250, flying in the night sky, and the wind is roaring around. If anyone who doesn't know hears it, they may think that there is a tornado approaching.

Although he had expected the result, he could not. He was still a little disappointed. Sitting on the console, he lost the interest of chatting with Mei and wild LAN for a while.

Stupefied just a few seconds, two arms at the same time a soft, but fell into a soft and warm place

As soon as Fowles was stunned, he realized what had happened, but he did not know how to turn his head.

Mei and Yuan Ye Lan, one of them, came forward and hugged one of his arms for comfort.

For a moment, Fowles didn't know whether to turn left or right. He was really in a dilemma!

Although it is difficult, the haze that the goal has not been achieved has been forgotten in a moment. Although the sound barrier has not been broken through, the speed is enough. Anyway, those close fighters can't catch up with them. If they meet the saint level or space master, it will be useless to speed up

It's natural to be depressed When a new idea came into being, Fowles looked at the two girls strangely: "do you know what 3P is?"

……

The speed of the plane is about 250 kilometers per hour.[because even the constant of the universe has changed, even the basic elements of the world are no longer what they were. Of course, the speed of sound, the speed of light, and the units of distance can't be the same as the other universe. However, for the convenience of story telling, let's acquiesce ]

it's impossible for three people to be in the same bed together. It's not that there is no place. The main thing is that one of the three people must fly the plane.

So the next time, still spent in the knowledge of the two girls, because in addition to explaining to the two women, Fowles also had to instill some relevant information about the plane into the core soul of the magic tower.

After the birth of the core soul of ordinary magic tower, they still need to be taught, not to mention the alternative aircraft magic tower.

"This Can something called an anemometer really measure velocity? How was it measured? "

"If you flatten a piece of cloth and run in front of it, will it bulge back? The faster you run, the more bulging the cloth will be. As long as you accumulate enough data, you can judge your running speed through the uplift speed... "

What about the altimeter

"There's a parameter called air pressure..."

"Just now, you used to control the plane flying forward, backward, backward I remember that as long as my magic tower deviates slightly, it may roll and fly out. According to your opinion, the angle between gravity and anti gravity deviates and no longer acts on a line. How do you solve this problem? "

"There's something called a gyroscope. Have you ever seen a top... "

Time, in such a question and answer, unconsciously passed, until, a ray of strong orange light from a certain direction, shining on the plane.

The horizon is the morning glow burning like fire. At the bottom of the morning glow, a round of tomorrow immersed in the boundless sea is eager to try and burst out.

The sky and sea line, gold scales broken waves, high altitude overlooking more confused, people can not help but linger on selfless.

The fiery light sprinkled on the magic tower of the plane through the clouds, shining into the bottom of everyone in the tower.

They can't help but look at the direction of sunrise, watching the sun rise slowly, first narrow leaves, then as usual, then into a gourd, and finally suddenly jump, completely free from the embarrassment of competing with the reflection in the sea, and emit the light of the world alone.

The two girls sighed.

Women, always can't bear the fleeting beauty on a good day, feel for the passing of the beauty, and forget that the flowers will bloom, and the sun will rise after sunset

Looking at the two goddesses, Fowles slowly shook his head and continued to operate the plane. However, he took back his eyes and looked forward to the front. His eyelids leaped in vain. Of course, it was not like the two girls who were sad and nostalgic, but the coastline in front of him No mistake. There's a coastline in front of him.

The speed of the plane was about 850 kilometers per hour. After a whole night, it was winter, and the night was quite long. After flying for about 134 hours, the flight distance was more than 10000 kilometers. Finally, it successfully crossed the East China Sea of Pavel, and flew directly to the coast of the East China Sea from near the Tongtian current.

The construction of golden village is still going on, and the training of goblin fleet is also continuing. Although the test of overlord has passed, it will take at least a month to integrate new people into it.

Even if the goblin fleet sets out now and moves the training of its crew to warships, it will take at least a month before it can reach Pavel from the open sea

After leaving Pavel for a long time, Fowles could not wait. So he built the plane, and immediately galloped to this place.

When may and wild orchid get rid of the sunrise scene, Fowles has controlled the magic tower of the plane to complete the deceleration, stealth and landing operations.

A few hundred meters from the ground, Fowles opened the hatch and jumped out, flying fast to the ground.

There is no GPS system or google map in this world. Although he flies back to Pavel, he has no idea where he is.

However, through the huge telescope air mirror condensed in the magic tower, Fowles had already seen clearly that someone was walking through the mountain area below, so he wanted to go down and ask the man exactly.

Driving wind fell into a group of people. The closer he got to the ground, the more he found out that the situation was wrong. He saw that these people were dressed in rags, with fresh complexion, and their facial expressions were numb. They were like the legendary refugees.

"Excuse me..." Fowles fell to the ground and spoke only two words. The marching crowd found him in vain. The original dull and wooden movement was suddenly full of vitality and hope.

"Master master! help! Master A group of old and small people, crying for their father and mother, came to Fowles and cried for help.
