Chapter 336: Ballistic Missile (6)

After Zhao Zhongyao chose a place to build and develop ballistic missiles, he took a large freighter with these soldiers and returned to Jianghai City.
Next he handed over the task to Yan Mingcheng. He wants to build a simple test base on Shark Island within a month. Fortunately, a month later, he and some scientific researchers will go there to develop and produce ballistic missiles.
Yan Mingcheng listened to Zhao Zhongyao's words and naturally went to handle it immediately.
After Zhao Zhongyao arranged these basic things, he returned to the military factory.
What he has to do now is to design the drawing of the ballistic missile.
Only with blueprints can the development of ballistic missiles be carried out!
Because of the complex structure and large size of ballistic missiles, Zhao Zhongyao had to consult a lot of information before designing it.
Although Zhao Zhongyao was reborn from the relatively developed China before his death to this relatively backward China.
But he was a pure theoretical physicist before, and his main research was nuclear physics.
Although many advanced weapons make use of the basic knowledge of physics, after all, doing basic research in physics is not the same as developing weapons and ammunition. This cannot be compared.
That is, Zhao Zhongyao has been in the military industry for more than a year since this period of time, and has a good understanding of military technology.
Otherwise, if he were to directly develop this ballistic missile, he might not have a clue!
Fortunately, this time, he already had extensive experience in missile research. It is not that difficult to study such a super weapon again.
But no matter what, this is a challenge to Zhao Zhongyao. If he wants to develop a super missile, he must first learn relevant knowledge.
For Zhao Zhongyao, in his last life, he had only heard of ballistic missiles. He doesn't know much about the real principles.
However, after all, he was also an old military fan in his last life. He also learned a little about all aspects of military industry knowledge, and he also learned a little about this ballistic missile weapon.
Now he wants to develop this super weapon himself, he must first think about some of the performance of this weapon!
Ballistic missiles are divided into short-range missiles, medium-range missiles and long-range missiles. Among them, long-range ballistic missiles are also called intercontinental missiles.
Ballistic missiles are mainly used to attack fixed targets on the ground. After launching, the missile flies very high and the speed is very fast. When the missile finally strikes the target, it can reach ten times the speed of sound.
At this speed, there is no weapon that can intercept it. In this kind of high-speed flight, the inertia of the missile itself is very large. Even if an ordinary missile is successfully intercepted, it is difficult to completely destroy it.
What's more, at this speed, almost no missile can intercept it. After all, the speed is too fast. It is very difficult to intercept a very fast weapon at high altitude.
Although the speed missile developed by Zhao Zhongyao is already very fast, it is only six times the speed of sound. And this kind of ballistic missile can reach ten times the speed of sound in the final attack.
Why this missile can fly so fast. And ordinary missiles can't fly so fast! There are some objective reasons for this.
The reason why a ballistic missile can attack a target has a speed more than ten times the speed of sound. This is mainly because the missile is launched vertically. Always fly to an altitude of a thousand kilometers above the ground before doing horizontal flight.
Ballistic missiles can fly outside the atmosphere. There is very little air resistance. Therefore, ballistic missiles can obtain extremely fast initial speeds under the impetus of advanced aircraft.
When the ballistic missile flies for a certain distance and is ready to attack a target on the ground, it will dive from a high altitude and fly towards the target at a dive or even a vertical angle.
Ballistic missiles are relatively large in size and weigh several tons.
Once such a big guy dived down from high altitude, the gravitational acceleration it obtained can be imagined.
Driven by such a strong gravitational acceleration, ballistic missiles can naturally reach ten times the speed of sound.
With such extreme speed, of course no missile can intercept it. It can also accurately aim at the target and quickly destroy the target.
Ballistic missiles are so powerful, but it is not easy to develop and produce such weapons.
After a month of hard work, Zhao Zhongyao finally drew the blueprint of this ballistic missile.
Then they came to Shark Island with Yan Mingcheng, and they were about to develop ballistic missiles.
"Zhongyao, will we be able to develop this super weapon soon! At that time, this weapon will be the most advanced weapon in the world again!"
Yan Mingcheng looked at the drawing on the desk in front of them and chatted with Zhao Zhongyao.
"That may be true. Haven't we already got the information! Country M is also studying this kind of ballistic missiles! Maybe the ones developed by others are better than ours!"
Zhao Zhongyao doesn't dare to speak big words now, after all, the strength of Country M lies there! He now dares to say that the ballistic missile he developed will be better than the one developed by Jonis, which is hard to say!
"Zhongyao, what's wrong with you, haven't you always been very confident! Why, this time you don't have confidence anymore." Yan Mingcheng felt a little surprised when he heard what Zhao Zhongyao said!
"There is confidence. But I don't want to talk big, before I have developed this kind of missile, how can I guarantee that the missile I developed will be more advanced than the one developed by Jonis!
Only after the missile was developed first and then a test launch was conducted to know who developed a powerful missile! "
Zhao Zhongyao was not a braggart. At such a critical moment, he naturally didn't want to talk nonsense.
"Zhongyao, you have to know that the several missiles you developed before are all more advanced than those developed by Jonis! Why, this time, are the missiles you developed really difficult? Why, there is no confidence in the past. Yeah!"
Yan Mingcheng was still a little strange. He thought, Zhao Zhongyao was very confident when he developed any kind of missile before. He has always said that the missile he developed must be better than the one developed by Jonis! But this time, Zhao Zhongyao seemed to be less confident.
"Well, don't you know! The technical difficulty of developing this ballistic missile is much more difficult than the previous missiles!"
When Zhao Zhongyao was in the military factory, he had already read a lot of missile release documents. He knew that ballistic missiles could fly very fast, and there are very high technical requirements to maintain a stable posture.
The previous missiles were flying at low altitudes. As long as they have a powerful enough engine, they can fly quickly. As long as the ground radar is also very advanced, it can cooperate with this kind of missile to reach the point where no one can attack.
However, this ballistic missile is completely different from previous missiles. This missile wins mainly by altitude. Its trajectory has basically been determined before launch, and it will not change direction during the flight.
The missiles developed before, such as the cruise missile developed last time, are different. This missile can fly in the sky like an airplane, and it can also change the direction of the missile as needed.
The ballistic missile developed this time is different. This is a missile that flies in a predetermined orbit.
The speed of this missile when attacking is very fast, almost ten times the speed of sound. At this speed, a strong friction force will be generated between the warhead of the missile and the air.
This kind of friction can make the warhead of the missile instantly generate thousands of degrees of high temperature.
At such high temperatures, any known metal on the earth may melt. If the missile’s warhead melts while the missile is in flight, it is dangerous. It is very possible that the missile has already detonated by its own high temperature when it has not bought the target position.
If this is the case, then this kind of missile doesn't need to hit the enemy's target, it will be destroyed by itself.
Therefore, to develop this kind of missile, the first thing to pass is to find a metal that can withstand high temperatures of several thousand degrees. Only by finding such a metal can such a missile be successfully developed.
But even if the problem of the high-temperature resistant metal of the warhead is solved, there is another problem next!
It is the question of how to maintain balance during the flight of the missile. We all know that objects are very unstable when flying at high speed in the air. It is easy to roll over.
For example, we made paper airplanes when we were young.
Just find a piece of paper, fold it into a paper airplane, and then go out.
Since we do not understand aerodynamics, it is impossible to use these advanced theories on a paper airplane.
In this way, the paper airplanes that we folded usually rolled in the air for a few times when they were still going out, and then swayed to the ground.
Only occasionally, the paper airplanes we fold are slightly in line with some knowledge of aerodynamics, so that the paper airplanes we fold can travel a certain distance in the air in a more graceful posture.
The reason why the aircraft can fly steadily in the sky is because the layman of the aircraft must take into account the principles of aerodynamics when designing it. Only an aircraft designed as an "aircraft" can be balanced in the air. flight.
If you don’t consider aerodynamics, even if you design an airplane that looks exactly like a real airplane, it won’t fly.
The reason why the airplane can fly steadily in the sky is because the shape of the airplane is designed using the principles of aerodynamics, especially when the wing is designed with this problem in mind.
And how do humans understand this knowledge, then we have to thank the birds flying freely in the sky!
It is precisely from the flight of birds that humans have learned the principles of aerodynamics, so that they can develop high-altitude aircraft such as airplanes.
The reason why birds can fly freely at high altitude is precisely because the shape of birds is completely in line with the principles of aerodynamics.
It is from the flying skills of birds that humans have mastered the principles of aerodynamics, so that human aircraft can fly in the sky.
The missiles developed by humans also need to comply with the principles of aerodynamics. Otherwise, after the missile is launched, it will only turn around in the air, and it is impossible to attack the target.
At this point, missiles are similar to bullets.
When the bullets in the gun were fired, it was difficult to reach the target and the accuracy was poor.
This is mainly because the barrel of the original gun was smooth. After the bullet is shot out of the barrel, due to its high speed, it is easy to generate huge friction with the air.
The bullet is very small and light. In this case, the bullet will somersault in the air after being fired from the smooth barrel without rifling.
Although people can't see bullets turning somersaults in the air with naked eyes. But theoretically speaking, the bullet will definitely somersault in the air. This is especially true when the wind speed is relatively high.
Of course, now people can see the trajectory of bullets fired from the barrel with high-speed cameras.
But no matter what, the first gun sights developed by mankind are very poor and it is difficult to hit distant targets.
Later, people used the principles of aerodynamics, and later people were inspired by small things like tops, knowing that objects can maintain a relatively stable posture when they rotate.
So people think about how to make the bullet have a rotating posture when it comes out of the barrel, so that the bullet will naturally not turn around.
Later, people thought of a method of designing rifling in the barrel to solve the problem of the bullet coming out of the barrel, continuing to fly, and maintaining a balanced flight state.
So later, almost all of the barrels of guns designed by people are rifled. Only such guns can have high shooting accuracy.
But the missile is a big thing. It cannot be shot from the barrel like a bullet. The missile is launched from a missile launcher.
During the flight of the missile, it is impossible to keep it in a rotating position. How can the flight stability of the missile at high altitude be ensured without rotating?
This is about to equip the missile with the tail. The empennage of a missile is a measure that allows the missile to maintain its balance during flight.
But this kind of measure can only solve the flight problem of general missiles. Because the flight speed of general missiles is not too fast. At most one to two times the speed of sound. Some can even fly at subsonic speeds.
For example, cruise missiles can fly at high altitudes at subsonic speeds and constantly change their flight attitude so that the missile can accurately lock onto the target.
The speed of ballistic missiles is very fast, reaching almost ten times the speed of sound. At this speed, the role of the tail is not great. If you want the ballistic missile to maintain a balanced state in the process of flying to the target, you have to think of some other smart tricks.
