Because airplanes fly 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 reduce the weight of the object as much as possible.
The reason why light can run 'fast'. It is because photons have very little mass. Photons are about the same mass as electrons and much smaller than protons and neutrons. So, photons can travel at the speed of light.
Particles like protons and neutrons can only travel at speeds far below the speed of light. That's just over a million kilometers per hour. And the speed of light is one billion eighty million kilometers per hour! The speed of the two cannot be compared at all!
Of course, these are the world of microscopic particles, which are different from our real world. In the real world, very few objects can achieve such speeds.
The speed of the fastest spacecraft developed by human beings is the third cosmic speed, which is 16.7 kilometers per second. That 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 only more than 40,000 kilometers. With the fastest speed of a human spaceship, 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 the interstellar space, it will appear very slow.
In the 1970s, people launched a space probe, the Voyager spacecraft. This spaceship travels through the solar system at the third cosmic speed, and it has been flying for more than 30 years before barely flying out of the inner solar system.
Everyone knows that the Oort cloud is the real edge of the solar system. Now the Voyager is flying towards the Oort cloud, but it will take hundreds of years to fly to the Oort cloud in the outer solar system, which is the edge of the real solar system!
That is to say, this fastest spaceship developed by mankind wants to fly out of the solar system. It would have to travel hundreds of years in the solar system first.
And it may take 80,000 years to fly to the neighbor of the sun, Proxima Centauri! It may take 3.8 billion years to fly out of the Milky Way. And it will take six billion years to fly to the nearest galaxy to us, a little brother of the Milky Way, the Large Magellanic Cloud.
And the Large Magellanic Cloud. Only the satellite galaxies of the Milky Way are only 160,000 light-years away from the Milky Way. The nearest large galaxy to us, the Andromeda Nebula, is more than two million light-years away from our Milky Way.
It will 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, and humans already know it. The age of our entire universe is between 13.7 billion and 13.8 billion years. However, if a human aircraft wants to fly to the nearest large galaxy, it will take more than 70 billion years to fly. This time is unimaginably far away.
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 according to scientists' calculations, our Milky Way may meet her big sister, the Andromeda Galaxy, in three billion years.
When these two sisters meet, it may be the end of our universe. Because when two galaxies collide, it's 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 collisions between stars. Because the distance between the stars is very far, it can easily be several light-years to tens of hundreds of light-years!
Even if two galaxies collide, the stars may still be safe! But no matter what, the collision of two galaxies will increase the temperature of the entire galaxy a lot!
Because in the star space of the galaxy, there are also a lot of thin interstellar gas and dust. these things. In the collision of two galaxies, it will be constantly rubbed and heated. As a result, the temperature of the entire galaxy will increase a lot.
The stars that exist in these interstellar gas and dust will of course increase their own temperature. The temperature of the star increases, and those large planets near the star. It will also catch fire.
The temperature on a planet determines whether life on the planet can survive. The reason why the earth can breed life is because it has a unique temperature environment suitable for the existence of life.
But once two galaxies collide, it is considered that there is no collision between the stars, but as the temperature of the stars rises, life on the planets will be wiped out.
So, human aircraft. Traveling in the universe at the third cosmic speed may never fly out of our galaxy.

Gossip less, the book returns to the main story.
The atomic missile that Zhao Zhongyao is going to develop now is to increase the flight speed of the air defense missile!
But how can we increase the flight speed of anti-aircraft missiles! He knew that two points must be done in order to increase the speed of the anti-aircraft missile!
First, the weight and volume of air defense missiles should be reduced as much as possible. Now the s-3 air defense missile he developed has a body length of ten meters, a diameter of one meter, and a weight of more than ten tons!
It is difficult for such a missile to exceed Mach 2 with an ordinary engine and liquid propulsion.
And now the speed of the enemy's high-altitude reconnaissance aircraft is Mach 3. those who want to catch up with others
For a high-altitude reconnaissance aircraft, the speed of the air defense missile must reach Mach 3 or more!
Zhao Zhongyao knows that if he wants to increase the flight speed of the air defense missile, he must first reduce the weight of the air defense missile. In other words, the volume of anti-aircraft missiles should be reduced. Such cumbersome anti-aircraft missiles 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 the anti-aircraft missile fly a longer distance!
This is really a pair of contradictions! To increase the speed of the missile, it is necessary to reduce the weight of the missile. However, the importance of reducing missiles also means reducing the weight of fuel. Without enough fuel, how could it be possible to launch the 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 anti-aircraft missile still has a strong thrust and can fly a long distance while reducing its size and weight, it can only work on the engine of the missile.
The normal motor engine before. Obviously not suitable for use, the new type of missile he wants to develop, the extremely fast missile he wants to develop must use a new type of atomic engine!
Zhao Zhongyao found out all the drawings of the atomic engine he had designed before. Then, after further research and thinking, he had to think about how to further reduce the size of this atomic engine. This can be used on his new anti-aircraft missiles.
To reduce the size of the previous atomic engine, the only thing to do is to further reduce the core of a small atomic reactor!
Only by shrinking this atomic reactor further. Only then can it be installed on the new air defense missile he designed.
Zhao Zhongyao decided that the new air defense missile he designed would only be 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 its diameter will not exceed half a meter. It weighs no more than five tons.
And the flight distance of this new type of missile is farther than the original air defense missile, at least more than 300 kilometers. And the flight speed must exceed Mach 3. Only in this way can the enemy's high-altitude reconnaissance plane be shot down!
certainly. The reduction in size can only be done by modifying some data on the design drawing. This problem is not a problem at all.
However, on the issue of the core engine of the anti-aircraft missile, how to further reduce and double the power of the engine is something that makes Zhao Zhongyao a little difficult.
The small atomic reactor he developed before was already the smallest limit he could design. If this limit is exceeded, the reactor will not work. And now I want to use this reactor on air defense missiles. Then at least the volume of the original engine should be reduced to half!
"What to do, how can I further shrink this small reactor and make it work normally!" Zhao Zhongyao stared at the blueprint of the small reactor he designed before, and fell into a helpless distress.
Zhao Zhongyao has a habit. Just when I think about problems, I like to smoke. This seemed to help his thinking.
In fact, he is not a smoker, no matter whether he was alive or after his death, he did not feel disgusted by smoking.
But when he is researching problems, especially when he encounters some problems that cannot be solved. He has the feeling of smoking. So, I would light a cigarette and walk around the office while thinking about the problems I wanted to solve.
This time, it was the same. Zhao Zhongyao encountered a somewhat difficult problem, so he took out a cigarette from the cigarette case, lit it, and walked around the office while smoking.
Because his thoughts were more concentrated, when he was thinking about problems, he forgot to smoke again. So the cigarette was burning between his fingers!
"Oh!" Zhao Zhongyao was thinking about a problem when he suddenly felt a pain between his fingers. He instinctively raised his hand to see what was going on.
It turned out that when he was thinking about the problem just now, he forgot to smoke. As a result, the burning cigarette butt was scalded.
"Yes, why don't I develop a small atomic reactor! Let the uranium be burned in the 'briquettes', and the volume of the atomic reactor can be greatly reduced!"
Zhao Zhongyao really inspired him because he burned the cigarette butt! From the burning cigarette in his hand, he thought of the uranium rods burning in the reactor!
He wants to design a small atomic reactor to be used on the new anti-aircraft missile he wants to develop! In this way, the core problem of the new air defense missile can be solved!
With this whimsical 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 already feels a little dizzy now. Because, he has not eaten anything for more than ten hours, nor has he drank a drop of water!
But thinking that he finally solved the core technical problems of the new air defense missile, he still laughed excitedly.
Just then, he heard someone knocking on his office door!
"Please come in!" Zhao Zhongyao put the design drawings on the desk, then returned to normal, and said looking at the door.
"Squeak!" The door opened,
Yan Mingcheng walked in with a smile.
"Zhongyao! How about it, is there any progress in the new missile you developed! In the past few days, the enemy's high-altitude reconnaissance plane has been reconnaissance of military intelligence in our country's airspace! And our ordinary air defense missiles can't hit them at all! I wonder if your new air defense missile has been designed yet!"
Yan Mingcheng is also very anxious these days!
Because the enemy's high-altitude reconnaissance plane successfully 'destroyed' an anti-aircraft 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 now and then to spy on military intelligence!
As for Yan Mingcheng's troops, they could only watch and have nothing to do.
Because if they launch anti-aircraft missiles, they will only waste these expensive 'shells'! Not only can't catch up with other people's high-altitude reconnaissance planes, but they will also be "destroyed" by other people's high-altitude reconnaissance planes!
Yan Mingcheng has also been very anxious these days. Seeing the enemy plane flying above his head, he wished he could pick up the machine gun and shoot! But he knew it was pointless to do that. So he thought about asking Zhao Zhongyao to develop the new air defense missile quickly, so he would be so angry!
Today, the enemy's high-altitude reconnaissance plane is showing off its power over Jianghai City again! Yan Mingcheng couldn't sit still anymore. He came directly to Zhao Zhongyao's office in the military factory.
When Zhao Zhongyao saw that it was Yan Mingcheng, he knew why he came. Of course, I want to know what happened to the new anti-aircraft missile he developed!
"Haha, it's really time for you to come! I just had an idea and solved the most critical problem! I have also designed the blueprint of the atomic reactor! But I have been there for more than ten hours and have not eaten or drank water I don't know, can you invite me out for a meal!" Zhao Zhongyao looked at Yan Mingcheng pretending to be mysterious and smiled.
