 Chapter 775 Data cabin, data cabin! !

 Every student who has fallen into the sea from a height of 10,000 meters knows this.

 The higher you are and the faster you go, the harder the water feels when you hit it.

 Generally, if it falls over 100 meters, the 'effect' is basically the same as falling on the concrete floor.

 Many marketing accounts or so-called popular science bloggers will tell you that this is because water has surface tension, but in fact it is not the case.

 The actual reason for this situation is actually the incompressibility and inertia of water under normal conditions.

for example.

 For example, if you put your finger in the water, what happens?

Your fingers occupy the space where the water originally existed. This part of the water moves due to force, making room for your fingers.

 This part of water is still surrounded by incompressible water and cannot merge with this water, so it can only squeeze the water in other locations and let it bulge toward the water surface.

In other words, when a finger enters the water, it is the movement of water that squeezes the volume of a finger, and there is no buffer time.

Hence, the starting point is ripples when the speed is low, and splashing when the speed is high.

This is what happens when the human body enters water. If you want the water to get out of the way within 0.1 seconds, the force required is not very large, but your speed is too high. If you want the water to get out of the way within 0.0001 seconds, the inertial force of the water is very huge. The human body can't stand it.

 The current Dongfeng-2 is the same.

When it fell into the water, its speed was close to Mach 10. The moment it was subjected to the inertial force of the water surface, cracks appeared on its surface because it could not bear this force.

 In a short period of time.

　　　　　　　　　　　　　　　　　　　　　　　　 industries

These cracks quickly expanded to the entire surface of Dongfeng-2, and at the same time touched the receiving structure of the warhead.

  In 0.003 microseconds.

 The nuclear fuel in the warhead completed the chain reaction instantly. The fission reaction in the first step occurred at a temperature of approximately

  15 million degrees.

This temperature is not actual measured data. The calculation principle is to convert the average kinetic energy taken away by the reaction fragments into temperature. That is, the characterization method is the average kinetic energy of particles in a certain volume within a short period of time.

 Follow.

 Huge radiation energy is quickly transmitted to the secondary through the radiation channel in the form of soft X-rays, compressing the lithium deuteride in the secondary.

 Within three microseconds.

After the lithium deuteride is compressed, it also squeezes the "spark plug" composed of uranium 235, causing it to exceed the critical state.

 At this time, the neutrons generated by the secondary explosion just enter, igniting the "spark plug" and causing a fission explosion.

In this way, the primary explosion and the "spark plug" explosion work together on the lithium deuteride layer, forming an internal and external pincer attack, which finally generates a high enough temperature and density to trigger the fusion reaction.

 The temperature at this time is as high as .

  150 million degrees!

Theoretically, at this temperature, any substance will instantly turn into fly ash—except for Boruto.

but

 Don’t forget, this is not land, and the missile does not penetrate straight into the water. Its trajectory is a dive at the end of a parabola, and there is an angle between the warhead and the horizontal plane.

 The value of this included angle is not an arbitrary number. Its value has been accurately calculated in advance, and its size is.

 14.86°!

 For the structure of Dongfeng-2, this angle combined with the ocean environment will create a miracle in the field of physics.

 According to historical development.

In December of this year, physicist Freeman Dyson, the inventor of the Dyson sphere concept, will write a famous memo.

In the memo, he discussed eight possible new weapons systems that appear to be possible in the near future. Dyson also outlined the potential military uses and potential hazards of each of these systems.

One of the eight ideas Freeman discussed in the memo was to use gigaton nuclear weapons to cause waves.

There is a rather horrifying passage describing the effects of detonating a gigaton mine in the Mariana Trench:

"Quantitative analysis of the damaging effects has not yet been conducted. Rough estimates suggest that the resulting waves would be 200-300 feet (about 60-90 meters) above sea level, or within 200-300 miles (320-480 kilometers) of the coast. land area—it depends on which limit the wave reaches first."

However, later research by Bernard Le Mevot refuted this conjecture. He proved another physical process:

 When a nuclear bomb explodes underwater, it will create a cavity filled with hot gas. This cavity will first evaporate the seawater, and then the cavity will float up to form a huge water mushroom.

  In other words.

And if the missile dives into the sea at a certain speed, its own impact force will first squeeze out an area without seawater, and then the air will expand in volume when heated, and the vacuum zone will draw in the nearby low-altitude air, thereby generating airflow from below. Hold the clouds.

In the gradient descent method, the iterative formula is xk+1=xkγf(xk), where γ is a fixed value greater than 0.

 Assume that each xk comes from a continuous function X:R+Rn, that is, the divergence of nuclear bomb energy is 360 degrees, and further assume that each divergence is random.

 Then there will be X(t+γ)xk+1=X(t)xkγf(X(t)).

This form is very interesting. If γ→0, then the left side of the formula is the derivative of X at t. In this way, X is the solution of the following ordinary differential equation:

˙ X˙(t)=f(X(t)).

 If you replace the gradient flow by linear interpolation between each test point in gradient descent, you will find that one of the trajectories is empty.

 Introducing the structural parameters of the Dongfang-2 missile, the incident angle corresponding to this trajectory is.

 14.86°!

 That is, due to the opposition of air flow and heat, this area will form a vacuum area that will not be affected by impact and high temperature.

This area is also called the saddle point, which means the lowest point of the saddle.

This concept can be roughly understood as the eye of a typhoon. Even for a level 17 super typhoon, the eye of a typhoon is still extremely calm—although this explanation has nothing to do with intercontinental missiles.

Of course.

There is still a distance between this area and normal temperature. After all, it only isolates conduction and convection. The heat brought by radiation cannot be isolated. After all, this thing carries rays.

 But due to the lack of the first two, the temperature of this saddle point can only reach seven or eight hundred degrees.

 For a data cabin made of high-temperature resistant materials, this temperature is still three to four hundred degrees Celsius away from its limit.

 That’s right.

 At this moment, the object appearing in this area is the missile's data cabin!

 During the previous discussion on missile matters within the base, some comrades once raised a question:

The temperature at the explosion center of the missile is extremely high. If it is a huge object, such as a cruiser or aircraft carrier, there may be some remaining parts of the body, but the data warehouse is only the size of a washing machine. How can this thing be at the center of the explosion? How to preserve it under high temperature?

For this reason, some base leaders also believe that the data module may fall off first and appear one or two kilometers away from the center of the explosion, so that it can be safely avoided from turning into ashes.

Opponents believe that this approach will affect the trajectory of the missile, and the parameters recorded by the data cabin should also include certain data at the moment of the missile explosion. If it falls off first, a lot of core information will be missed.

 At the time of the stalemate between the two sides.

Yu pushed up his glasses and quietly took out the saddle point area data he had calculated. (Note: In the original history, the saddle point was calculated by Yu, and what was very outrageous was that the 150 computer team of Yanda was doing the calculations at the same time. Yu Da The 150 machine calculated the saddle point six hours in advance)

 This is also the wonder of physics.

It can give particles a spin of 1/2, allow matter to appear as a wave-colored Einstein condensate, allow the detector returning to the earth to float gracefully in a waverider orbit, and can also allow hundreds of millions of people to float There is a relatively low-temperature "forbidden zone" in a high-temperature environment.

 If you don’t learn mathematics, physics and chemistry, life will be full of magic.

Looking back to reality.

The size of the data cabin has also been calculated in advance. The moment it leaves the missile body, the data cabin the size of a washing machine enters a special saddle point area.

The homeomorphic structure of the Calabi-Yau manifold allows the shock wave to quickly form a hedging area according to the mathematical rules of the Jacobian determinant, like the center point of a vortex, with the surrounding "water flow" (actually energy) rotating at high speed, but It remained motionless.     Then a few seconds later.

  The data capsule floated up with the cavity and sprayed to the highest point of the water mushroom.

And then.

 Under the influence of gravity, it completed a fall of several hundred meters.

 After falling back to the sea.

˜The two programs inside the data cabin entered the startup state at the same time.

The first program is a small ball similar to a gyroscope. According to the design of Qian Wushi and others, it will automatically emit dye to mark its position after seven minutes, which is the theoretical maximum duration of the surge.

 As for the second procedure.

 Its countdown time is a little longer, up to fifteen minutes.

However, although the time of this program is long, the meaning it represents is not very beautiful - it is a countdown device.

If the rabbits cannot find the data cabin and enter the correct password before the countdown, it will actively self-destruct.

At that time, the rest of the countries will certainly not be happy, but the hard work of the rabbits will also be in vain.

 At this moment.

 The outside world.

With the explosion of the missile, a water column hundreds of meters high instantly filled the field of vision of everyone at the scene.

 The huge sound shocked not only everyone's eardrums, but also their hearts.

 At this moment.

 The neon Bailu command ship.

Looking at the water column more than 20 nautical miles away, Hanprey absentmindedly pinched the wound he had made earlier:

 “Oh God, the Chinese have really developed an intercontinental missile”

Hampry had participated in many nuclear tests across the sea before coming to Asia. He was still at the scene when the first Atlas intercontinental missile exploded.

As an experienced 'industry insider', he naturally made an accurate judgment at the first opportunity - this is definitely a powerful intercontinental missile!

even

 Even stronger than Jupiter!

  In other words.

From today.

Another country in the world has mastered intercontinental missiles. Although this missile is still more than 200 kilometers away from the intercontinental range in terms of range, this is obviously just a deliberate move by the Chinese.

 The world situation is becoming increasingly complex.

However, Hanprey's absence only lasted for a few seconds, and his entire attention returned to reality:

“Marchione, contact Keisuke Sugawara immediately and tell him that he must grab the Chinese data cabin!”

“At the same time, all helicopters will be dispatched to search the sea surface. If the indicator area is found, report immediately!”

“By the way, I remember that the Maple Leaf Kingdom’s warship at that position is the Kingston?”

Marchionne nodded immediately:

 “Yes, the captain is Major Highbury.”

The navy of the Maple Leaf Kingdom is called the Royal Navy of the Maple Leaf Kingdom. From the literal meaning, it is not difficult to see that there is an inseparable relationship between it and John Bull.

Historically, this navy was officially established under the name of George V. The entire navy's equipment was also provided by John Bull. It is one to two generations behind the active fleet of John Bull.

ˆ “.”

Hampry was silent for a few seconds, and finally a trace of cruelty flashed in his eyes:

“You go contact Highbury and the Xianyang on the other side of China, and ask them to do everything possible to prevent the Chinese from getting the data capsule.”

“In addition, privately tell Highbury to evacuate the crew to the deck and prepare lifeboats.”

Marchionne was startled for a moment, and it took him a few seconds to realize what Hampri was thinking:

 “Mr. Hemprey, what do you mean?”

Hampry glanced at him, with a sad expression on his face:

“After today, China is no longer the same China. At least we must use the so-called ‘reason’ when dealing with them.”

“Okay, we are pressed for time, please contact them quickly, and tell Highbury that we will compensate them with a better warship than Kingston.”

Marchionne was silent for two seconds, and then nodded heavily:

"I see."

 After Marchionne leaves.

Hampry walked to the window alone and looked at the surging sea in the distance.

As the core consultant across the sea in the Asia-Pacific region, Hanprey has seen all kinds of storms, but throughout the first half of his life, he has never experienced such a situation.

 He became a witness to a historical node, and all the instructions he gave were likely to change the future of the entire human race.

 At the same time that Hanpri gave instructions.

 On the ocean a few nautical miles away from them.

Wang Anyi also held the handle of the cabin with both hands, looking upright at the explosive heart in the distance.

The height of the water mushroom is about two to three hundred meters high, and its range is about a hundred meters. The waves set off by the water column continue to surge outward like a tsunami.

Even though they were several nautical miles away from the center of the blast, the carrier-based craft still encountered strong surges.

If it were a hundred meters further, the small boat probably wouldn't be able to survive the surge for half a minute.

Think of this.

Wang Anyi couldn't help but glance at Shu Xingbei, who was already vomiting wildly.

Although this little old man has a bad temper, he is really capable.

 Hurrah.

 The turbulent waves kept washing against the hull of the carrier-based boat, but as time passed, the undulations of the sea gradually began to calm down.

 Then quickly.

　　Dududu.

 The sound of a helicopter appeared above everyone's heads.

Three or four of the helicopters are Z-5s that the Rabbits have completed test flights but have not yet finalized and put into production, but the majority are reconnaissance aircraft from European and American countries.

These helicopters are equipped with divers, who can launch people into the water as soon as the beacon is discovered.

However, the final salvage work of the data module still needs to be completed by the ship. After all, its size and weight are not small, and some of its parts need to be processed as soon as it is salvaged and put on the ship.

Then Wang Anyi glanced at Keisuke Sugawara behind him and was about to give the order to move towards the center of the explosion.

As a result, before he could speak, Gui Zhaolin's voice came from the communication device:

“Old Wang, the indicator area of ​​the data cabin has been found!”

Note:

  Thanks to the leader who rewarded friend 33021211001677! The boss is awesome! !
