Chapter 467 Black Dragon Express (Guarantee 1)

The atmospheric density of the ionosphere is very low, which can be seen from the fact that there are satellites in the ionosphere.

Therefore, when flying in the ionosphere, air resistance is negligible.

Under continuous acceleration, Fang Yuan's speed reached Mach 5, which is 5 times the speed of sound, 6120 kilometers per hour.

Eventually, it hits the stratosphere at Mach 5.

"Pay attention to the temperature! Pay attention to the temperature! Pay attention to slow down, 30 seconds, and 30 seconds before hitting the ground!" Yang Yuping shouted into the communicator, his voice was very anxious.

Since being able to crystallize dark matter and create strong interaction materials, Fang Yuan has a deep understanding of the properties of super strong interaction materials.

It is precisely because of knowing the properties of strong interaction materials that I decided to play such a big game.

Entering the atmosphere at 5 times the speed of sound, this speed has already competed with the intercontinental missile Dongfeng Express.

If it is a missile, it will rush into the atmosphere at 5 times the speed of sound, and the heat generated by friction with the air will make the shell temperature reach one or two thousand degrees.

As a result, the outer layer of the missile will turn red, as if it is burning.

In the same way, meteors do not burn in outer space, but start to burn when they enter the atmosphere.

The meteors across the sky that can be seen by the human naked eye are all meteors that have entered the atmosphere.

Two thousand degrees of high temperature.

Under normal circumstances, it is difficult for humans to withstand such high temperatures.

However, when Fang Yuan was wearing the black dragon armor and rushed into the atmosphere at Mach 5, the expected burning situation did not appear.

If it was a missile, the casing would have already burned red.

However, the black dragon battle armor still maintains the color of the black crystal shield armor, without any sign of burning.

Fang Yuan was also very nervous, and had been paying close attention to the temperature inside the armor. After entering the stratosphere, the temperature did not increase significantly, and finally confirmed that the nature of the strong interaction force material was as strong as expected.

The strong interaction force material is a layer of material formed by atoms locked by the strong interaction force and arranged closely together.

This kind of material naturally exists in the universe, that is, neutron stars, the densest stars in the universe except black holes.

The strength of the strong interaction force material is so terrifying.

Also because the atoms are closely arranged, the particles hardly vibrate, which makes the strong interaction force material belong to the thermal insulator.

Because there is no particle vibration, theoretically, the temperature of the strong-interaction material is absolute zero, and because it is a thermal insulator, it does not absorb heat itself, so no heat transfer occurs when touched, so it does not feel cold.

It is precisely because of knowing the special properties of strong interaction materials in advance that Fang Yuan dared to rush into the stratosphere at 5 times the speed of sound.

After entering the stratosphere, it passes through the ozone layer and continues to rush down to the troposphere, like a vertically falling missile, locking on to the target on the ground and rushing straight down.

hum!

After 20 seconds, it passed through the stratosphere and rushed into the troposphere, only 15 kilometers away from the ground.

"Slow down, slow down quickly." Yang Yuping kept reminding, but to no avail.

According to the speed of Mach 5 and the altitude of 15 kilometers, it can be crossed in less than 10 seconds, and then it will directly hit the ground.

At this time, Admiral Rhodes also said: "Slow down, this is an order."

Fang Yuan also didn't want to try what it would be like to hit his head and break his blood, so after entering the troposphere, he started to slow down.

After 10 seconds, it falls to the ground at subsonic speed.

Boom!

There was a loud bang, and both feet fell to the ground,

Step the ground out of two holes.

After three seconds of silence, there was a burst of warm applause.

clap clap...

The first test of the Black Dragon Armor is over.

Fang Yuan returned to the suit lab, took off the black dragon armor, and handed it over to the lab for optimization and perfection.

"Do you have any comments on the suit? We will try our best to optimize it according to your wishes." The researchers in the suit laboratory checked the condition of the suit and asked.

"I think the appearance can be more domineering, and, has the name 'Black Dragon' been decided? It doesn't match my handsome appearance. I think it's okay to be a little white dragon in the waves." Fang Yuan rubbed He rubbed his chin and said.

Admiral Rhodes heard it from the side, and couldn't help but roll his eyes despite his age, and said: "This is because you are too young and don't look very powerful in appearance, so you use the code name 'Black Dragon', It will appear more stable and cover up the shortcomings of your appearance."

"My appearance has become a weakness? Don't they say that appearance is combat power?" Fang Yuan was speechless.

...

After testing the Black Dragon armor, Fang Yuan found that the armor design team of the Academy of Military Sciences is still very strong.

Originally thought that the black dragon battle armor produced would be similar to the Longwei class battle suit.

But after testing, it was discovered that the Black Dragon Armor is much stronger than the Longwei Class Armor.

In fact, if you think about it carefully, you will understand.

The Longwei-class battle suit is a mass-produced suit, and the pursuit is to reduce the cost as much as possible while ensuring a certain combat effectiveness.

In other words, Longwei-class battle suits have high requirements for cost performance.

The Black Dragon Armor is different. If there are no special circumstances, only one set will be made, so it is no problem to spend billions of dollars in it.

A lightning vortex ring propulsion engine cost three billion, which was made on the premise of omitting the electron beam generator.

After the first test of the Black Dragon Armor, after two days of optimization and adjustment, Fang Yuan received a notice to start the second test of the Black Dragon Armor.

There are engineers with superpowers who are responsible for manufacturing the battle suits. The speed of optimization and adjustment is really fast, and the process is almost purely manual.

The second test was carried out in the test field of the Academy of Military Sciences. Although it was an open-air test field, this time it was a ground test.

"The optimization process went very well this time. After loading the strong interaction force material, the Black Dragon suit weighs 280 kilograms. Adding your weight, the total weight reaches 350 kilograms. This weight is much heavier than ordinary suits. Today we need to test the movement of the ground to see if it will hinder the movement." Professor Yang Yuping roughly talked about the content of today's test.

"350 kg? In this case, wouldn't the kinetic energy of the Dragon Fist increase five times?" Fang Yuan was very satisfied with this weight.

According to the kinetic energy formula Ek=(mv^2)/2, mass is directly proportional to kinetic energy, and the kinetic energy increases as many times as the mass increases.

"The premise is that you are carrying such a heavy armor, and your speed has not slowed down." Yang Yuping corrected.

Calculated according to the kinetic energy formula, if the speed decreases, the kinetic energy will naturally decrease.

The greater the weight of the armor, the lower the speed will naturally be.

Therefore, whether the final kinetic energy will increase or decrease depends on the test results.

The ground speed is not the same as the sky speed tested a few days ago.

The reason why it was able to reach 5 times the speed of sound last time was to start accelerating outside the atmosphere. Outside the atmosphere, there is no air resistance, so it can accelerate to Mach 5.

In theory, flying in space, as long as the acceleration is maintained, it can continue to accelerate to the speed of light.

However, it is different on the ground. With the existence of air resistance, the speed will have a limit.

When fighting, there is no time to go to outer space to complete the acceleration process.

Therefore, the speed data on the ground is more important.
