Liu Qingquan took the data of the whole vehicle and looked carefully. The entire anti-gravity flying car has a length of 3.3m, a height of 2.2m, a front width of 1.2m, and a tail width of 1.7m. From the top, it is a trapezoid, which is about 50cm taller than an ordinary car.

Two anti-gravity engines are installed at the bottom to achieve vertical and rapid take-off and landing. At the same time, because of the use of anti-gravity technology, the aircraft can use the powerful gravity of the earth and fly very fast. The maximum speed is expected to reach Mach 40 and the normal working speed is Mach 30. What is the concept of such a speed? The radius of the earth is about 6376km and the circumference of the equator is 40041km. Based on the normal working speed of Mach 30, it only takes an hour to fly around the earth. The speed is very terrifying. The fastest target on the earth should be the intercontinental missile, but the fastest speed when it hits the target is only Mach 20. It can be said that when driving such an aircraft, there is no weapon on the earth that can catch up with it. It is definitely a black technology.

The overall material of the aircraft is a new material developed and produced by Liu Qingquan using Alpha's scientific and technological knowledge. The density is similar to that of ordinary aluminum alloys, so the weight of the whole vehicle is about the same as that of ordinary cars, 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 material is light and hard, it has reached an amazing 101. The hardness of diamonds, that is, diamonds are 100, which means that their hardness is a little stronger than diamonds. This technology alone can be said to be a historic progress, because so far, any scientific research institution has produced materials with hardness of more than 100. It is important to know that materials with hardness of more than 100, ordinary processing methods are useless at all, because no processing tool can process materials with such hardness. However, this is obviously not difficult for Liu Qingquan, who has seeds.

In addition to the characteristics of low density, light weight and high hardness, new materials also have a very important feature. The characteristics of this material are very important in high-speed spacecraft, that is, thermal conductivity. The thermal conductivity of the new material is very poor. It can be almost said to be thermal insulation. Insulation materials are the materials that countless aviation people dream of. As we all know, high-speed spacecraft are too fast and friction with the air will generate very huge heat. Everyone knows that sound barriers will occur when the speed exceeds Mach 1, and heat generated by too fast speeds will not be dissipated, and whether the heat can overcome the thermal barrier can be said to be a key technology of high-speed spacecraft. The thermal insulation performance of new materials can ensure that even if they fly at a speed of up to Mach 40, there is no need to worry about thermal barriers.

Let’s talk about the flight altitude. Because it uses anti-gravity technology, the higher the anti-gravity capability, the weaker the anti-gravity capability. Therefore, the aircraft designed flight limit altitude is 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 high-level atmosphere. The altitude of the troposphere will vary due to the terrain distribution. Generally, between 0.9 kilometers and 18 kilometers, the troposphere atmosphere is frequent and is not suitable for aircraft flight. Under normal circumstances, aircraft and other aircraft are flying in the stratosphere, that is, about 10 kilometers to 50 kilometers above the ground. The flight altitude designed by Qingquan Technology’s anti-gravity aircraft is quiet and well-designed, which is within the stratosphere, and the flight is relatively safe.

...

Liu Qingquan walked over excitedly, reached out to touch the cold body with emotion, opened the car door familiarly, and sat on it. On the first test flight, Liu Qingquan ignored everyone's persuasion and insisted on doing it himself. In Liu Qingquan's opinion, no one knew everything about it better than himself. Every component on it embodies his own countless hard work and sweat. In order to be able to come up with a mature design as soon as possible, Liu Qingquan often studies it with everyone on the same time, and at the same time, he also goes to seed space to accelerate the learning of Alpha's scientific knowledge to explain it to others. It can be said that Liu Qingquan has basically not slept in the past few months, but fortunately he can practice so that he can hold on.

At this time, Liu Qingquan was not tired at all. On the contrary, he was very excited, excited, happy.... He first looked at the internal situation carefully. The driving design of the anti-gravity flying car was similar to that of an ordinary car. There was an additional handle on the right side of the steering wheel, through which the aircraft could be operated to fly up and down. There was a balance display and an altitude display in the instrument display. The balance display was used to display the horizontal balance of the aircraft. An aircraft using anti-gravity technology,

They are all very stable. The altitude display is used to display flight altitude and is a must-equipped equipment for all aircraft. The speed controller on the far right has three modes: low-speed car mode, take-off and landing mode, high-speed flight mode, and low-speed car mode can make anti-gravity flying cars fly at a height of tens of centimeters off the ground like ordinary cars; take-off and landing mode uses force to take-off and landing to fly cars; high-speed flight mode can only be started after the aircraft is above 20,000 meters and is used for supersonic flight.

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

"Boom~~~" The aircraft made a low and powerful sound. Everyone saw the aircraft slowly rising to a height of 20 cm from the ground, and then black smoke came out from the tail, slowly starting, like a car walking on the ground, constantly doing various acceleration, turning, and deceleration movements, which were no different from ordinary cars.

After flying at an altitude of 20 cm for a few minutes, the aircraft slowly stopped and then slowly rose to a height. It was still very slow at the beginning, but later it became faster and faster. Soon the aircraft disappeared from everyone's sight.

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

"Ah~~" Liu Qingquan felt the land of the motherland for the first time so beautiful and charming. He couldn't help but howl loudly. He gently pushed the height handle with his right hand, and the numbers on the altitude instrument kept jumping, 5000, 7000, 12000, 20000... As the altitude continued to rise rapidly, Liu Qingquan only felt that he was pressing on the seat tightly. Soon the aircraft had already arrived at the stratosphere, and the indicator light of the high-speed flight mode had turned green. Liu Qingquan gently activated the high-speed flight mode, and then stepped on the accelerator under his feet.

"Boom~~~" The aircraft vibrated hugely, and then Liu Qingquan was pressed tightly on the seat by acceleration, and the muscles in the whole body felt an abnormally heavy feeling. In just five seconds, a circle of ripple appeared outside the aircraft, which was a sound barrier generated when the speed exceeded the speed of sound, and then the speed continued to increase.

"Mach 1, Mach 5, Mach 15, Mach 30" Just when Liu Qingquan was almost unable to open his eyes, Liu Qingquan finally stopped stepping on the accelerator. In just under 2 minutes, his speed reached a terrifying speed of Mach 30. The acceleration generated was even caused by Liu Qingquan who practiced the advanced cosmic Yuanli technique like Liu Qingquan almost collapsed. Fortunately, he relaxed the accelerator in time. Liu Qingquan slowly adapted to the high-speed flight. When there was no acceleration, he relaxed. The sky outside was sky blue, and below were layers of continuous white clouds, allowing you to put the Buddha 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 constantly circling and never tirelessly.

Perhaps because he was tired of playing the circle game, Liu Qingquan identified a direction, and the aircraft drew a beautiful straight line and flew at high speed. He dragged a long white tail behind him, like a white light shot towards the sky.

Zhong Jinfei is a ground radar monitor in the Guangzhou Military Region. As usual, he is watching the radar leisurely while playing with his mobile phone and chatting with his girlfriend. The main job of the radar station is to provide ground navigation to aircraft in the sky. There is not much in a day, so Zhong Jinfei's work is very easy. Generally, when the monitoring aircraft is monitored, it sends messages to check. If the verification is correct, it provides the other party with latitude and longitude coordinates. The other party can determine his position by relying on the provided latitude and longitude coordinates, so that he will not lose his direction.

"Dou~~Dou" The radar alarm monitored the new target and issued an alarm sound. Zhong Jinfei quickly put down his phone and looked at the surveillance screen. "Nothing is there! Is the radar broken again?" Zhong Jinfei looked at the Kongkong screen and murmured to himself.

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

"Hello? I just repaired the radar not long ago." Zhong Jinfei stared at the scene.

"Boom~~Boom" an arc flashed from the picture. Zhong Jinfei opened his mouth wide, and what could be so fast. Then before he could think about it, the alarm sounded again, and another arc appeared in the picture. Zhong Jinfei quickly picked up the phone and reported the situation to his superiors. No matter whether it was an alien or something, the speed was too scary.

Zhong Jinfei stared at the radar screen tightly. The arcs would appear every few seconds in a very regular manner. The alarm kept beating. Zhong Jinfei referred to the speed of the plane. If this arc was really something that could fly, its speed was as high as a terrifying Mach 30. Oh my God! Intercontinental missiles did not have such speed! Is there really an alien?

Zhong Jinfei kept staring at the radar screen. Not long after, a straight line flashed from east to west in the screen. After that, no matter whether it was an arc or a straight line, the sound of the radar beeping finally calmed down. Zhong Jinfei knew that this thing had flown out of the range of his radar monitoring, and breathed a long sigh of relief. People always had a strong curiosity for unknown things and were accompanied by an extremely fear.
