Liu Qingquan took the data of the whole vehicle, and looked at it carefully, the entire anti-gravity flying car, with a length of 3.3m, a height of 2.2m, a front width of 1.2m, and a tail width of 1.7m, is a trapezoidal shape from the top, and the height is about 50cm higher than that of ordinary cars.

Two anti-gravity engines are installed at the bottom, which can achieve vertical rapid take-off and landing, and because of the use of anti-gravity technology, the aircraft can fly very fast with the help of the strong gravitational pull of the earth, and the maximum speed is expected to reach Mach 40, and the normal working speed is Mach 30. What is the concept of such speed? The radius of the earth is about 6,376 km, the circumference of the equator is 40,041 km, and at a normal operating speed of Mach 30, it only takes one hour to fly around the earth. The speed is very terrifying, the fastest target on the earth should be an intercontinental missile, but the fastest speed when it hits the target is only Mach 20, it can be said that with such a flying machine, there is no weapon on the earth that can catch up with it, proper black technology.

The overall material of the aircraft is a new material developed and produced by Liu Qingquan using the scientific and technological knowledge of Alfa person, and the density is about the same as that of ordinary aluminum alloy, so the weight of the whole vehicle is about the same as that of an ordinary car, weighing about 1.3 tons, which is very light, of course, only such a light weight can make the flight speed reach a maximum speed of Mach 40.

Although the hardness of the material is very high, it reaches an astonishing 101, and the hardness of diamond is 100, that is to say, its hardness is a little stronger than that of diamond, and this technology alone can be said to be a historic progress, because so far any scientific research institution has manufactured more than 100 hardness of materials, to know that the hardness of more than 100 materials, ordinary processing means are useless, because there is no processing tool can process such a hardness of materials, but, This is obviously difficult for Liu Qingquan, who has seeds.

In addition to the characteristics of low density, light weight and high hardness, the new material also has a very important feature. The material properties are very important in high-speed spacecraft, that is, thermal conductivity, the thermal conductivity of the new material is very poor, it can almost be said that it is thermal insulation, and thermal insulation materials are the materials that countless aviation people dream of. As we all know, the high-speed spacecraft is too fast, and the air friction will produce a very huge amount of heat, we all know that when the speed exceeds Mach 1, there will be a sound barrier, and the heat generated by too fast will produce a thermal barrier if it is too late to dissipate, whether it can overcome the thermal barrier can be said to be a key technology of high-speed spacecraft, the thermal insulation performance of the new material can ensure that even if it flies at a maximum speed of Mach 40, there is no need to worry about the thermal barrier.

Let's talk about the flight altitude, because the anti-gravity technology is used, the higher the anti-gravity ability, the weaker the anti-gravity ability, so the aircraft is designed to fly at a limit altitude of 50 kilometers, and the normal flight altitude is between 20 kilometers and 40 kilometers. As we all know, the earth's atmosphere can be roughly divided into troposphere, stratosphere and upper atmosphere, the height of the troposphere will be different because of the terrain distribution, generally 0.9 kilometers to 18 kilometers, the troposphere atmosphere is frequent, not suitable for the flight of aircraft; under normal circumstances, aircraft and other aircraft are flying in the stratosphere, that is, about 10 kilometers to 50 kilometers above the ground, and the flight altitude of Qingquan Technology's anti-gravity aircraft is quietly good and it is in the stratosphere, the flight is relatively safe.

……

Liu Qingquan walked over excitedly, stretched out his hand to touch the cold car body with emotion, opened the car door familiarly, and sat down. On the first test flight, Liu Qingquan insisted on coming by himself despite the persuasion of all the people. In Liu Qingquan's view, no one knows everything about it better than himself, every part on it has condensed his countless hard work and sweat, in order to be able to come up with a mature design as soon as possible, Liu Qingquan is often studying normally with everyone on the one hand, and on the other hand, he has to go to the seed space to accelerate the learning of the scientific and technological knowledge of the Alfa to explain to others, it can be said that Liu Qingquan has basically not slept in the past few months, but fortunately, he can cultivate, so he can survive.

At this time, Liu Qingquan was not a little tired at all, on the contrary, he was very excited, excited, and .......happy, and first took a closer look at the internal situation, the driving design of the anti-gravity flying car is similar to that of an ordinary car, and there is an extra handle on the right side of the steering wheel, through which the aircraft can be operated to fly up and down; Where is the balance display and altitude display in the instrument display, the balance display is used to show the horizontal balance of the aircraft, the aircraft using anti-gravity technology is generally very stable, the altitude display is used to display the flight altitude, and it is a necessary equipment for all aircraft; The speed controller on the far right has three modes, low-speed car mode, take-off and landing mode, and high-speed flight mode, and the low-speed car mode can make the anti-gravity flying car fly at a height of dozens of centimeters above the ground like an ordinary car; take-off and landing mode: force, vertical take-off and landing, flying car; The high-speed flight mode can only be activated after the aircraft is above 20,000 meters and is used for supersonic flight.

Liu Qingquan fastened his multiple seat belts and gently clicked the start button.

"Boom~~~" The aircraft made a low and powerful sound, and everyone only saw the aircraft slowly rising to a height of 20 cm above the ground, and then black smoke came out of the tail, slowly starting, like a car walking on the ground, constantly doing various acceleration, turning, and deceleration actions, and there is no difference from ordinary cars.

After flying at an altitude of 20 centimeters for a few minutes, the aircraft slowly stopped, and then slowly rose to a high place, at first it was very slow, then faster and faster, and soon the aircraft disappeared from view.

Liu Qingquan looked at the height displayed on the instrument, 3210m, at this time looking down, everything has become very different, the beautiful scenery of the golden autumn in Liuyun Town is even more beautiful at this moment, the people below are like ants, the car is like a toy, the river is a long line, and even the mountains everywhere have become so short.......

"Ah~~" Liu Qingquan felt for the first time that the land of the motherland was so beautiful and moving, and couldn't help but howl loudly, his right hand gently pushed the height handle, and the numbers on the height meter kept jumping, 5000, 7000, 12000, 20000...... As the height continued to rise rapidly, Liu Qingquan only felt that the whole person was pressed against the seat. Soon the aircraft had come to the stratosphere, and the indicator light of the high-speed flight mode had turned green, Liu Qingquan gently started the high-speed flight mode, and then stepped on the accelerator under his feet.

"Boom~~~" There was a huge vibration of the aircraft, and then Liu Qingquan's whole person was pressed on the seat by acceleration, and the muscles of the whole body had an abnormal feeling of heaviness. It only took five seconds for a circle of ripples to appear on the outside of the aircraft, which is a sound barrier created when the speed exceeds the speed of sound, and then the speed continues to increase.

"Mach 1, Mach 5, Mach 15, Mach 30" Just when Liu Qingquan couldn't even open his eyes, Liu Qingquan finally didn't step on the accelerator again, and in less than 2 minutes, the speed soared to a terrifying speed of Mach 30, and the acceleration generated was almost collapsed even by a person like Liu Qingquan who had cultivated the Universe's Advanced Yuan Force Technique, but fortunately he released the throttle in time. Liu Qingquan slowly adapted to the high-speed flight, when there was no acceleration, the whole person was loosened, the sky outside was sky blue, and below was a mountain composed of layers of endless white clouds, making you feel like you were in the fairyland in the sky.

Liu Qingquan excitedly controlled the steering wheel, and the aircraft drew huge circles in the sky, just like a naughty child who kept going round and round forever.

Perhaps tired of playing the game of circles, Liu Qingquan identified a direction, and the aircraft drew a beautiful straight line, flying at high speed, dragging a long white tail behind it, like a white light shooting into the sky.

Zhong Jinfei is a ground-based radar monitor of the Guangzhou Military Region, and as usual, he leisurely watched the radar while playing with his mobile phone and chatting with his girlfriend. The main job of the radar station is to provide ground navigation for the planes in the sky, and there is not much in a day, so Zhong Jinfei's work is very easy, and the general monitoring of the aircraft will send a message to check, and the check will provide the other party with latitude and longitude coordinates, and the other party can determine its position by relying on the latitude and longitude coordinates provided, so as not to get lost.

"Beet~~Beep" The radar alarm monitored the new target and sent out an alarm, Zhong Jinfei hurriedly put down his mobile phone and looked at the monitoring screen. "Nothing! Could it be that the radar is broken again? Zhong Jinfei looked at the empty picture and muttered to himself.

"Tut~~Tut" Just as he was about to pick up his mobile phone again, the radar sounded the alarm again, but when Zhong Jinfei looked over, there was nothing.

"What the hell? I overhauled the radar not long ago. Zhong Jinfei stared at the screen.

"Toot ~ ~ Toot" An arc flashed away from the picture, Zhong Jinfei's mouth opened wide, what is it, how fast can it be, and then before he could think about it, the alarm sounded again, and another arc appeared in the picture, Zhong Jinfei hurriedly picked up the phone and reported the situation to his superiors, whether it was an alien or something, this speed was too scary.

Zhong Jinfei stared at the radar picture, the arc will appear every few seconds very regularly, the alarm has been beeping non-stop, Zhong Jinfei refers to the speed of the plane, if this arc is really something that can fly, its speed is as high as Mach 30, oh my God! ICBMs don't have such speeds! Are there really aliens?

Zhong Jinfei has been staring at the radar screen, not too long, a straight line appeared in the picture from east to west flashed, and then whether it was an arc or a straight line, the radar beeping sound finally quieted down, Zhong Jinfei knew that this thing had flown out of the range of his radar monitoring, and breathed a long sigh of relief, for unknown things, people always have a strong curiosity and a sense of incomparable fear.

Liu Qingquan didn't know at this time that the anti-gravity flying car he was driving had attracted the attention of all the countries along the way, as long as it was a place to pass, the radar pictures on the ground all showed a straight line and disappeared, and the countries along the way thought that it was monitoring the alien aircraft, and the whole country was mobilized, and China and other major countries even changed their orbits to monitor every move in the sky.
