Chapter 310: Touch the sound barrier (three shifts)

When the awakened people heard these three words, expressions of astonishment appeared on their faces.
For bullets, supersonic speed is basically arbitrary super.
However, it is not so easy for the awakened.
In fact, if you want a fist to be supersonic, there is a very clever way, that is, sitting on a subsonic plane and punching, the fist will be supersonic.
Of course, this statement is just a joke.
It is very difficult for the awakened to break through the speed of sound by running.
However, if it is a fist, it is relatively easy.
Fang Yuan's current running speed has reached 527 km/h. If his fist can play 3 times the speed, it is a steady supersonic speed.
However, it is hard to say whether it can be achieved.
Because these two characteristics may not be able to work on the fist, or improving efficiency may not be the same as running.
The specific situation can only be determined through testing.
"Sonic boom fist is a literal meaning, a fist that makes a sonic boom. Fang Yuan, you are responsible for explaining what a sonic boom is." Admiral Rod said by name.
"why me?"
Fang Yuan is thinking about his own affairs, and there is no such thing as a tireless leisurely life for the time being, but he can think about it.
"I heard that you got good grades in cultural courses, so let's talk quickly." Admiral Rod urged.
"Sonic boom is the explosion sound made by squeezing the air when an object breaks through the sound barrier." Fang Yuan replied.
"The second question, explain the sound barrier again." Admiral Rod continued.
"Sound barrier means that when the speed of an object is close to the speed of sound, it will encounter a strong resistance, causing the object to vibrate strongly, which will cause the speed to decay. In other words, to break through the sound barrier, 340 meters per second is not enough. , Must exceed this value by a certain percentage." Fang Yuan continued to explain.
"Very well. To sum up, if you want to make a sonic boom, you need the speed of your fists to break through the sound barrier. And because the speed of your fists is 2 to 3 times the running speed, so when your running speed reaches 400 km/h At that time, there is hope that through training, you can hit a sonic boom." Admiral Rod explained.
Fang Yuan curled his lips and said, "It seems that the speed of one person here exceeds 400 km/h? What's the use of calling so many people together?"
The words came out.
The expressions on the faces of the remaining 11 awakeners who participated in the selection were as if they had eaten something.
Rage point +20.
Rage point +30.
Everyone contributed a sum of anger points, which adds up to 320 points.
Fang Yuan smiled satisfied, and said his heart: This is the right way.
Then, he was not polite at all and started adding points, consuming these 300 anger points, and continued to increase his agility, reaching the base agility to 193 points.
The speed is so fast, it can't be stopped.
"Okay, you all know the principle of sonic boom boxing, let's start practicing." After speaking, Admiral Rod turned and walked out of the field with his cane.
"That's it? What about good teaching?" Fang Yuan blinked his eyes, a little dazed.
"The master leads the door, and the practice is personal. I have told you the principle, do you still have to hold your hand and tell you how to punch?" Admiral Rod asked rhetorically.
"no need."
Fang Yuan was a little speechless, but he didn't continue to bludgeon him, and walked aside to start practicing.
Admiral Rod said something more: "Before punching, run at the limit speed and punch again, the success rate is higher."
"Got it."
Fang Yuan promised to activate "Lightning Speed" and "Wind Speed", burst out the limit speed, and then punched out.
There was no sonic boom.
I tried it two more times, but there was no sonic boom.
Fang Yuan walked back to the speed test booth, put the speedometer on his wrist, and tried two more punches.
After the fight came back and asked: "What is the speed of my fist?"
"The maximum speed is 1033 km/h." Analyst Chen Likun replied.
"Why is it so slow? My running speed is 527 km/h." Fang Yuan frowned and felt strange.
Analyst Chen Likun pulled out a lot of formulas and began to calculate and derive them.
Finally, I came to the conclusion: "Um...According to calculations, the fist-up efficiency of "Lightning Speed" has not been maximized."
Fang Yuan thought carefully, clenched his fist sharply, and said, "I know what's going on."
As a result, he walked out of the speed test booth again, condensed the "lightning speed" energy on his arm, and then burst out violently.
boom!
A thunder and lightning burst from his arm.
A punch came out.
A violent resistance was felt on the fist, and it was pressed against the fist like a shock wave, causing the fist to vibrate slightly.
Fang Yuan condensed his eyes and knew immediately that this was a sound barrier.
When the speed of an object approaches the speed of sound, it will squeeze the air.
And these squeezed air will also form a reaction force, like an explosion, forming a shock wave and counter-shock the fist.
The same principle applies to airplanes.
Aircraft technology was blocked by the sound barrier for a long time before breaking through the sound barrier.
Moreover, the aircraft cannot fly at a speed close to the speed of sound. If it exceeds Mach 0.9 and does not exceed Mach 1, the aircraft will vibrate violently and even cause accidents.
Mach is the unit of sound speed, and 1 Mach is equal to 340 meters per second.
Therefore, the speed of subsonic aircraft will remain below 0.9 Mach.
Fang Yuan's fist encountered a sound barrier, indicating that the punching speed was approaching 340 meters per second.
Turning his head to look at the analyst Chen Likun, he asked: "How is it? How fast?"
"The maximum speed is 336 meters per second, but after reaching this speed, it suddenly drops a bit and you encounter the sound barrier. You have to break the sound barrier to break through the speed of sound. However, the strength of 340 meters per second alone is Those who cannot break through the sound barrier must be faster than this." Analyst Chen Likun replied.
Fang Yuan pinched his chin and thought.
Analyst Chen Likun added: "Fang Yuan, if you work hard at your speed of improvement, you should be able to break through the sound barrier."
"No, I don't want to work hard. I want to rub the sound barrier on the ground."
Fang Yuan walked to the front of the locker in the training ground, opened his locker, took out his schoolbag, and took out a star core inside.
When trading with Davis Group not long ago, they actually got two star cores.
One is the lord-level lightning silver dragon core with "lightning speed" and "advanced agility enhancement".
There is also a star core of the Sky Predator with "Advanced Agility Enhancement".
Originally, the Sky Predator's star core was used to protect the bottom.
In case the "Lightning Speed" is not successfully absorbed, it can also absorb the "Advanced Agility Enhancement" of the Sky Predator Star Core.
However, the "Lightning Speed" was successfully absorbed later, so the remaining Sky Predator star core was temporarily put aside.
Now, if the "advanced agility enhancement" can be absorbed successfully, it would be terrifying.
...
Note: The values ​​of speed are all calculated on the basis of settings, not just filled in. The basic speed algorithm is 10 agility remaining, then square root. 10 is the comprehensive value of several air resistance coefficients, set to 10 for the convenience of calculation. The calculation method is self-consistent based on the setting.
