The sun is shining, the clouds are light and the wind is light!

A brand-new Wind Rider, Windranger 3.0 series, codenamed Raptor 0, domineering side exposed!

After three days and three nights of hard work by Shiwei foundry, a new generation of wind control car is freshly baked.

"Brother Xiu, let's go feel it first!" Xiao Su looked at the raptor he designed, perfectly presented, and his heart was happy.

"Okay, this name is quite domineering, Raptor!" Zixiu saw the two big words 'Raptor' sprayed on the front of the flying car, and laughed.

"I hope it can soar in the sky like a bird of prey!"

The seven-seater elongated body has a smoother streamline, the side wings are lengthened, the top is added to provide upward momentum, the tail is used for direction adjustment, and the humanized porthole design greatly improves the light effect of the riding space.

The two of them climbed the ladder and walked in.

The passenger space and the driving space are set separately, and the scale of the passenger space is much more spacious than the previous generation. On the seat, the leather seats with high comfort are added, and the fine snow mountain grizzly bear leather is soft and elastic, hand-sewn, and the stitching lines are clear and neat. Under the seat, there is a balance bar that can adjust the angle of the backrest, so that it will be more comfortable to take a nap and take a nap during a long journey, and the backrest will be lowered for a long journey.

The entire interior space, the main color of light gray, is low-key and luxurious, mild, and slightly textured.

"Xiao Su, when the Raptor No. 1 is built in the future, tell me, our St. Field family, you can buy one!" He was comfortable lying on the bearskin seat.

"No problem, do we still need to buy it between us, I will give you one!" Xiao Su bared his big white teeth and smiled happily: "It's just that the stone is a little troublesome, and it's not easy to collect!"

"Let's go to Phoenix this time, pay more attention, and maybe we can come across good stone materials!" he said.

"Well, hopefully!" Xiao Su nodded lightly, glanced at Su San's senior, and said, "Take off, hover over the Five Elements Sect for a while, and test it, if there are any mechanical failures!"

After Su San received the order, he immediately manipulated the control stick, first adjusted the position of the Raptor 0, and drove slowly on the take-off runway!

This special runway, built on a mushroom hill made of slag, extends for about 500 meters and is about 20 meters wide. The gel formed by the mixture of slag powder and mountain sand paves the road, which is smooth and wear-resistant, solid and durable. At the end of the runway, there is a mountain stream and a large canyon, with an open space and a constant wind, which is conducive to the rapid lifting of the wind speeder.

The Raptor 0 is getting faster and faster, and in a few seconds, at the end of the runway, it takes off!

Call!

This big iron bird, flying rapidly, a roar was deafening, alarming the birds in the mountains and forests, all pouring out of the nest, flocks of birds, flocks, completely unaware of what was happening, and did not know where this big bird was sacred, circling in mid-air, screaming non-stop.

Outside the porthole, the mountain is majestic, the cave is beautiful, the forest spring is clear, the strange stone is sagging, and it is a beautiful scenery!

Sou!

The speed of the wind wheel on the side increased again, and the speed of the top wind wheel also reached the limit, and the Raptor 0 rose at full speed, pulling vertically, and in an instant, it crossed the highest mountain here, pointing straight to the clouds.

Su San was in the control room, engrossed, controlling the wind wheel at the tail, adjusting the direction and rhythm of the flight!

"Mr. Su San, what is the clearance height now?" Xiao Su was a little nervous, after all, this is the first time that the Wind Rider series has sprinted to the extreme altitude of 10,000 meters in the air.

"Back to the young master, I just flew past a height of 3000m!" Su San looked at the scale reading on the display instrument and replied.

Zixiu leaned his face against the porthole and glanced down, the highest peak before became as small as a thin needle. His heart was beating and accelerating with the flight altitude, and he couldn't stand it anymore, so he closed his eyes directly, his nerves were tense, and his hands were clutching the handrails.

Or Su San's psychological quality is better, his face is calm, he is not alarmed, he controls the control stick steadily, and steadily increases the altitude of the flight, even in the dense clouds, his eyes are dim, and he is also calm as water, indifferent.

"Young master, third son, we are about to reach an altitude of eight thousand meters, you sit tight!" Su San pressed the control rod of the flank wind wheel to the minimum, and then, the speed of the wind wheel was raised to the limit, and the climbing speed of the Raptor 0 increased again.

At an altitude of 8,000 meters, it was clear, like a calm blue ocean, with a few clouds, like a dreamlike blue hue, perfect.

He and Xiao Su looked out the window and couldn't help but let out an exclamation!

'Wow'!

"It's beautiful, it's like a peaceful ocean!" he looked at the blue sky, and his heart instantly relaxed.

"Yes, I didn't expect it to be so beautiful here!" Xiao Su smiled easily, not nervous at all.

Call!

Soon to reach the free layer at an altitude of 10,000 meters, Su San controlled the raptor, slowed down the speed of climbing, and the speed of the tail wind wheel began to accelerate, adjusting the overall coordination.

"You sit tight, when you first reach the free layer, there may be a little instability!" Su San reminded.

Airplanes!

At this time, only the noise of the rotation of the wind wheel remained, and the Raptor 0 successfully passed through the atmosphere and reached the free sphere above the Hanhai Sea, where the air was thin, there was no wind and no clouds, and the friction of flight became smaller.

The raptor stopped climbing and began to move smoothly on the horizontal plane.

Shout!

"Not good!" Su San suddenly shouted, his expression unusual.

Zixiu and Su Daozhi didn't know what was going on, they had just sat down, and suddenly, instantaneously weightless, Raptor 0 suddenly lost its upward traction, and the top wind wheel seemed to have a mechanical failure, and without any warning, the traction plummeted.

Call!

Like a bird with folded wings, the bird of prey swooped down, and in just three seconds, it descended more than 1,000 meters, and the speed of descent is still accelerating!

Su San was already sweating profusely, and his two hands worked together to control the control lever of the lifting wind wheel, and the two of them sat in the back, dazed, and their first reaction was to attract the true power in the dantian, and they were ready to give up the Raptor 0 and jump out of the window to escape.

8000m！

7000m！

6000m！

The raptor falls vertically at a speed of one kilometer in an instant!

5000m！

At a height of 5000m, the lift wind wheel, which has been stopped, slowly resumes its normal rotation, and the power of lifting gradually recovers!

At an altitude of 4000m, the raptor returned to normal, stabilized down, and no longer fell, Su San was already sweating profusely and soaking wet.

"What the hell is going on, how did a bird of prey fall vertically?" Xiao Su's face turned red, Xiao Su was shocked and asked eagerly.

"The Lift Wind Wheel, when it was in the free layer, it stalled in an instant!" Su San took a breath and replied weakly.

Stall is the turbine blades of the wind wheel, which stops rotating, which means that it loses power. There are generally two reasons for a stall: first, mechanical failure, and second, energy depletion!

At the time of the drop to 5,000 meters, the lift wind wheel regained power, indicating that the wind wheel did not suffer mechanical problems and did not run out of energy.

"Stall?" Zixiu looked at Xiao Su with an expression of disbelief, and he was a little afraid.

Xiao Su settled down and thought for a moment.

Syllable!

He slapped his head hard, and suddenly realized: "I know why it stalls, the air in the crescent layer is thin, so when the lift wind wheel rotates, the lift provided will be greatly reduced, and I have ignored the key knowledge points in fluid dynamics!"

The working principle of the lift wind wheel is that the air pressure above the rotating turbine blades is less than the air pressure below, and it is this pressure difference that provides the upward power. The air in the sphere is thin, so the pressure difference becomes very small, and the lift force is much smaller than the weight of the raptor, so the phenomenon of vertical fall occurs.

The vertical descent breaks the normal rotation of the turbine blades, and it will stall instantly!

"Xiao Su, you almost killed us!" he thought back to the scene of the flying down just now, and wanted to hit the careless designer twice.

"It's my mistake!" Xiao Su smiled embarrassedly and said, "Mr. Su San, let's return to the Five Elements Sect, it seems that Raptor No. 0 is not good, go back and have a good rest!"

"Yes, young master!" Su San began to control the joystick, turned the direction, and landed in the direction of the peak!

Fortunately, it was only a stall for non-mechanical reasons, otherwise, even if the three of them had a real power protector, they would fall from a height of 10,000 meters and not die, they would be half-disabled.

The design of the Raptor is a bold innovation in the Windranger series, and if successful, it will also have great significance in the history of aircraft manufacturing.
