Chapter 262: Atomic Missile (5)

Because the plane flies in the sky. Its internal parts should be as small and light as possible, and the weight of the aircraft itself should be reduced as much as possible. Only in this way can the aircraft fly higher, faster and more stable!
The speed of an object is often inversely proportional to the weight of the object. If you want to increase the speed of an object, you must minimize the weight of the object.
The reason why light can run so fast. It is because the mass of photons is very small. The mass of photons is comparable to that of electrons, much smaller than protons and neutrons. Therefore, photons can fly at the speed of light.
Particles such as protons and neutrons can only fly at speeds far below the speed of light. That is, the speed is more than one million kilometers per hour. And the speed of light is one billion eighty million kilometers per hour! The speed of the two is simply not comparable!
Of course, these are the worlds of microscopic particles, which are different from our real world. In the real world, it is very difficult for an object to reach such a speed.
The speed of the fastest spacecraft developed by mankind is the third cosmic speed, which is 16.7 kilometers per second. It is more than 60,000 kilometers per hour.
Such a speed is already quite fast on Earth. Everyone knows that the equatorial circumference of the terrain is more than 40,000 kilometers. At the fastest speed of a human spacecraft, it only takes more than half an hour to go around the terrain!
This speed seems to be very fast, but if it is placed in interstellar space, it appears very slow.
In the 1970s, they launched a space probe, the Voyager spacecraft. This spacecraft traveled through the solar system at the third cosmic speed. It flew for more than 30 years before barely flying out of the inner solar system.
Everyone knows that the Oort Cloud is the true edge of the solar system. Voyager is now flying towards the Oort Cloud, but it will fly to the Oort Cloud in the outer solar system, which is the edge of the real solar system. It will fly for hundreds of years!
In other words, for this fastest spacecraft developed by mankind to fly out of the solar system, it must travel in the solar system for hundreds of years.
And if it wants to fly to the neighbor of the sun-Proxima Centauri, it may take 80,000 years to fly! It may take 3.8 billion years to fly out of the galaxy. It would take six billion years to fly to the nearest galaxy, which is a little brother of the Milky Way, the Large Magellanic Cloud.
The Large Magellanic Cloud is just a satellite galaxy of the Milky Way, only 160,000 light-years away from the Milky Way. The nearest galaxy, the Andromeda Nebula, is more than two million light-years away from our Milky Way.
It would take more than 76 billion years for our spacecraft to fly to the nearest large galaxy, the Andromeda Nebula.
This is really an unimaginable time. Mankind already knows that the age of our entire universe is between 13.7 billion years and 13.8 billion years. As for a human aircraft, it would take more than 70 billion years to fly to the nearest large galaxy. At this time, the distance is unimaginable.
In fact, the Voyager may not even be able to fly out of the Milky Way, and he has already encountered the end of the universe.
Because scientists have not calculated that our Milky Way may meet her eldest sister, the Andromeda Galaxy, in three billion years.
When the two sisters met, it might be the end of our universe, because when two galaxies collide, it will be the worst traffic accident in the universe.
At that time, the solar system may also be wiped out in this super ‘traffic accident’. Of course, the collision of two galaxies does not necessarily cause a collision between stars. Because the distance between the stars is very long, there are several light-years to hundreds of light-years away!
Even if the two galaxies collide, the stars may still be safe and sound! But anyway, the collision of two galaxies will increase the temperature of the entire galaxy a lot!
Because there is also a lot of thin interstellar gas and dust in the star space of the galaxy. These things will continue to be friction and heating during the collision of the two galaxies. As a result, the temperature of the entire galaxy will rise a lot.
The stars that exist in these interstellar gas dust will of course also raise their own temperature. The temperature of the star rises, and the large planets near the star will also catch fire.
The temperature on the planet determines whether life on the planet can survive. The earth is able to breed life because it has a unique temperature environment suitable for life.
But once two galaxies collide, there is no collision between the stars, but as the temperature of the stars rises, life on the planets will disappear.
Therefore, human flying machines, which travel in the universe at the speed of the third universe, may never fly out of our galaxy.
Talk less gossip, the book is back to the main story.
The atomic missile that Zhao Zhongyao wants to develop now is to increase the flight speed of air defense missiles!
But how can we increase the speed of air defense missiles! He knows that two things must be done to increase the speed of air defense missiles!
First, we must minimize the weight and volume of air defense missiles. The S-300 air defense missile he has developed now has a body length of ten meters, a diameter of one meter, and a weight of more than ten tons!
Such a missile, with ordinary engines and liquid propulsion, can hardly exceed two Mach.
And now the speed of the enemy's high-altitude reconnaissance plane is Mach 3. If you want to catch up with other people's high-altitude reconnaissance aircraft, the speed of the air defense missile must reach Mach 3 or more!
Zhao Zhongyao knew that to increase the flight speed of air defense missiles, we must first reduce the weight of air defense missiles. In other words, to reduce the volume of air defense missiles. Such a heavy air defense missile can no longer be used.
But if the volume of the anti-aircraft missile is reduced, the importance of the engine and propulsion will also be reduced! Without a lot of fuel, how can air defense missiles fly longer distances?
This is really a contradiction! To increase the speed of the missile, it is necessary to reduce the weight of the missile. But the importance of reduced missiles is to reduce the weight of fuel. Without enough fuel, how can it be possible to launch a missile to a high altitude and fly a long distance!
Zhao Zhongyao really didn't know how to solve this problem for a while! He looked at the engine of the anti-aircraft missile he designed before.
He now knows that if the air defense missile still has a strong thrust and can fly a long distance even when its size and weight are reduced, the only way to do it is to work on the missile's engine.
The previous ordinary engine engines are obviously not suitable for use. The new type of missiles he wants to develop and the extreme speed missiles he wants to develop must use the new type of atomic engine engines!
Zhao Zhongyao found all the drawings of the atomic engine he had designed before, and then further studied and thought. He had to think about how to make the size of the atomic engine further shrink. This can be used in his new air defense missile.
To reduce the size of the previous atomic engine, the only thing to do is to further shrink the core small atomic reactor!
Only by further shrinking this atomic reactor can it be installed on the new air defense missile he designed.
Zhao Zhongyao decided that the new type of air defense missile he designed was only half the size of the original air defense missile.
In other words, the height of the new atomic missile will not exceed five meters, and the diameter will not exceed half a meter. The weight will not exceed five tons.
And the flying distance of this new type of missile is farther than the original air defense missile, at least more than 300 kilometers. The flight speed must exceed Mach 3. Only in this way can the enemy's high-altitude reconnaissance plane be shot down!
Of course, the size reduction is just to modify some data on the design drawing. This problem is not a problem at all.
However, on the issue of the core engine of air defense missiles, how to further reduce the size and double the power of the engine is something that makes Zhao Zhongyao a little bit difficult.
The small atomic reactor he developed before is already the smallest limit he can design. If this limit is exceeded, the reactor will not work. And now if I want to use this reactor on air defense missiles, I must at least reduce the size of the original engine to half!
"What should I do? How can I shrink this small reactor further and make it work normally!" Zhao Zhongyao stared at the small reactor blueprint he designed before, falling into a kind of helpless distress.
Zhao Zhongyao has a habit of smoking when thinking about problems. This seems to help his thinking.
In fact, he is not a person who loves to smoke. Whether it is during his lifetime or after his lifetime, he does not have the nausea of ​​smoking.
But when he was studying problems, especially when he encountered some unsolvable problems, he felt like smoking. As a result, he would light a cigarette and walk around in the office while thinking about the problem he wanted to solve.
This time, too, Zhao Zhongyao encountered a somewhat difficult problem, so he took out a cigarette from the cigarette case, lit it, and smoked while walking around the office.
Because of his concentrated thoughts, he forgot to smoke when he was thinking about problems. So the cigarette was burning between his fingers!
"Oh!" Zhao Zhongyao was thinking about a problem, and suddenly felt a pain between his fingers. He instinctively raised his hand and took a look before he knew what was going on.
It turned out that he forgot to smoke while thinking about the problem. As a result, the burning cigarette got hot.
"Yes, why don't I develop a small atomic reactor! Let the uranium burn in the ‘coal pellets’, then the size of the atomic reactor can be greatly reduced!"
Zhao Zhongyao really inspired him to burn the cigarette butt! From the cigarette burning in his hand, he thought of the uranium rod burning in the reactor!
He wants to design a small atomic reactor to be used in the new air defense missile he wants to develop! In this way, the core problem of the new air defense missile can be solved!
With this fantastic idea, Zhao Zhongyao quickly began to design this new type of small atomic reactor.
After more than ten hours of hard work without eating or drinking, he finally designed this small atomic reactor.
"Haha, great, I finally succeeded."
Although Zhao Zhongyao now feels a little dizzy. Because he hasn't eaten anything for more than ten hours, and he hasn't drank a drop of water!
Thinking about it, he finally solved the core technical problem in the new air defense missile, and he still laughed excitedly.
At this moment, he heard someone knocking on the door of his office!
"Please come in!" Zhao Zhongyao put the design drawings on the desk, then returned to normal, looked at the door and said.
"Squeak!" The door opened and Yan Mingcheng walked in with a smile.
"Zhongyao! How about it, is there any progress in the new missiles you developed! In the past few days, the enemy's high-altitude reconnaissance planes are spying on military intelligence in our country's territorial airspace! And our ordinary air-defense missiles can't hit anyone at all!" I wonder if your new air defense missile has been designed!"
Yan Mingcheng is also very anxious these few days!
Because the enemy’s high-altitude reconnaissance plane successfully ‘destructed’ an air defense missile over Jianghai City last time.
Now they are sending this kind of unmanned high-altitude reconnaissance plane to the sky above Jianghai City every few times, and they are investigating military intelligence!
And Yan Mingcheng's troops can only watch, but can't do anything.
Because if they fired anti-aircraft missiles, they would only waste this expensive ‘cannonball’! Not only can it not catch up with other people's high-altitude reconnaissance planes, but they will also cause them to be destroyed!
Yan Mingcheng is also very anxious these few days, watching the enemy plane flying at will above his head, he wants to pick up the machine gun and shoot! But he knew that it was meaningless to do that. So I wanted to ask Zhao Zhongyao to quickly develop a new air defense missile, so he could have such a bad breath!
Today, the enemy's high-altitude reconnaissance plane is showing its strength over Jianghai City again! Yan Mingcheng couldn't sit still. He went directly to Zhao Zhongyao's office in the military factory.
When Zhao Zhongyao saw Yan Mingcheng, he knew why he came. Of course, I want to know what happened to the new air defense missile he developed!
"Haha, it's really time for you to come! I just had a brainstorm and solved the most critical problem! I also designed the drawings of the atomic reactor! But I have not eaten or drink for more than ten hours. I don't know, can you invite me out for a meal!" Zhao Zhongyao looked at Yan Mingcheng pretendingly with a mysterious smile.
