After Zhao Zhongyao chose the place where he wanted to build and develop ballistic missiles, he and these fighters took a large cargo ship and returned to Jianghai City.

Next, he handed over the task to Yan Mingcheng. He wanted Yan Mingcheng to build a simple test base on Shark Island within a month, and he was fortunate to go to it with some scientific research personnel to develop and produce ballistic missiles a month later.

Yan Mingcheng listened to Zhao Zhongyao's words, so he naturally went to do it immediately.

After Zhao Zhongyao arranged these basic things, he returned to the military factory.

Now what he has to do is to design the drawings of the ballistic missile.

Only with drawings can we carry out the development of ballistic missiles!

Due to the complex structure and large size of the ballistic missile, Zhao Zhongyao also had to consult a large amount 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 purely theoretical physicist, mainly working on nuclear physics.

Although many advanced weapons make use of the basic knowledge of physics, after all, doing basic research in physics and developing weapons and ammunition are two different things, and this cannot be compared.

That is, Zhao Zhongyao has been working in the military industry for more than a year for a period of time, and he already knows a lot about military science and technology.

Otherwise, if he were to directly develop this ballistic missile, he might not have a clue at all!

Fortunately, this time, he already had a lot of experience in studying missiles before. It will not be so difficult to study such a superweapon again.

But no matter what, this is a challenge for Zhao Zhongyao, if he wants to develop a super missile, he must first learn relevant knowledge.

As far as Zhao Zhongyao is concerned, in his previous life, he had only heard of ballistic missiles. For the real principle. He didn't know much.

However, after all, he was also a veteran military fan in his previous life. He also learned a little about the military industry in all aspects, and he also learned a little about the weapons of this ballistic missile.

Now that he is going to develop this super weapon, he first has to think about some of the properties 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 stationary targets on the ground. Since this missile, after launch, flies very high and is very fast. At the time of the missile's final attack on the target, it can reach more than a dozen times the speed of sound.

At such a speed. There is no weapon that can intercept it. In this high-speed flight, the inertia of the missile itself is very large. Even if an ordinary missile succeeds in interception, it will be difficult to destroy it completely.

What's more, at such a speed, there are almost no missiles that can intercept it. After all, it's too fast. It's hard to intercept a high-speed weapon at high altitude.

Although the speed of the extremely fast missile developed by Zhao Zhongyao was already very fast, it was only six times the speed of sound. And this ballistic missile. The speed of the final attack can reach more than ten times the speed of sound.

Why can this missile fly so fast. And ordinary missiles can't fly so fast! There are some objective reasons for this.

The reason why ballistic missiles can attack targets has a speed of more than ten times the speed of sound. This is mainly due to the fact that this missile is launched vertically. It is necessary to fly to an altitude of 1,000 kilometers above the ground, and then do horizontal flight.

Ballistic missiles can fly outside the atmosphere. There there is very little air resistance. Therefore, ballistic missiles can gain extremely fast initial velocity under the impetus of developed aircraft.

And when the ballistic missile flew some distance. When they are ready to attack a target on the ground, they will fly towards the target from a high altitude at a dive or even a vertical angle.

The ballistic missiles themselves are relatively large, and they weigh several tons.

Such a big guy. Once it swoops down from a high altitude, the gravitational acceleration it obtains can be imagined.

Propelled by such a powerful gravitational acceleration, ballistic missiles. Naturally, it can reach more than ten times the speed of sound.

With such extreme speed, of course, no missile can intercept it. It can also aim at the target accurately and destroy it quickly.

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 drawings of this ballistic missile.

Then they came to Shark Island with Yan Mingcheng, and they were going to develop ballistic missiles.

"Zhongyao, will we be able to develop this super weapon soon! When the time comes, this weapon will be the most advanced weapon in the world!"

Yan Mingcheng looked at the drawings on the desk in front of them and chatted with Zhao Zhongyao.

"Maybe we have already got the information! Country M is also researching this kind of ballistic missile! Maybe they are developing it even better than ours!"

Zhao Zhongyao doesn't dare to say big things now, after all, the strength of country M is there! He now dares to say that the ballistic missile he has developed will definitely be more powerful than that developed by Joannis, and it is not easy to say!

"Zhongyao, what's wrong with you, haven't you always been very confident! Why, this time you don't have confidence. When Yan Mingcheng heard Zhao Zhongyao's words, he felt a little surprised!

"There is faith. But I don't want to say big things, before I develop this kind of missile, how dare I guarantee that the missile I developed will be more advanced than the one developed by Joannis!

Only after this kind of missile has been developed and test-fired can we know who has developed the most powerful missile!"

Zhao Zhongyao was not originally a person who loved to brag. At such a critical moment, he naturally didn't want to talk nonsense.

"Zhongyao, you must know that the several missiles you developed before were not all more advanced than those developed by Joannis! Why, this time, is it really difficult for the missiles you developed! Why, you don't have the confidence you had in the past!"

Yan Mingcheng was still a little strange, thinking that Zhao Zhongyao was very confident when he developed any kind of missile before, and he had always said that the missile he developed must be more powerful than that developed by Joannis! But this time. Zhao Zhongyao seems to be less confident.

"You don't know this! This ballistic missile is much more difficult to develop than the previous missiles in terms of technical difficulty!"

When Zhao Zhongyao was in the military factory, he had already read a large number of missile release materials, and he knew that ballistic missiles flew at a very fast speed, and there were very high technical requirements for maintaining a stable attitude.

The previous missiles were all flying at low altitudes, and as long as there was a strong enough engine, the missiles could fly very fast. As long as the ground-based radar is also very advanced, it can cooperate with this missile to the point where no one can hit it.

However, this ballistic missile is completely different from the previous ones. This missile wins mainly by height. Its orbit was basically decided before launch. It does not change direction during the flight.

And the missiles developed before, such as the cruise missiles developed last time, are different. The missile can fly in the sky like an airplane and can change its direction as needed.

This time, however, the ballistic missile developed is different, it is a missile that flies according to a predetermined trajectory.

The speed of such missiles when attacking is very fast, almost a dozen times the speed of sound. At such speeds, a strong friction force is created between the warhead of the missile and the air.

This friction can make the warhead of a missile instantly generate a high temperature of several thousand degrees.

At such high temperatures, any known metal on Earth can melt. If the missile is in flight. If the missile's warhead melts, it's dangerous. It is quite possible that the missile has already detonated itself at a high temperature when it did not buy the location of the target.

If that's the case, then this missile. You don't have to hit the enemy's target, you can destroy it yourself.

Therefore, in developing this missile, we must first pass a hurdle. It is to find a metal that can withstand thousands of degrees of heat. Only by finding such a metal can such a missile be successfully developed.

But even if it solves the problem of high-temperature resistant metal of the warhead. Next, there's another question!

It is a question of how to maintain the balance of the missile during flight. We all know that objects are very unstable when they are flying at high speed in the air. Tumbling is very susceptible.

For example, the paper airplanes we folded when we were kids.

I found a piece of paper, folded it into a paper airplane, and then went out.

Since we don't understand aerodynamics, it's impossible to use these advanced theories on a paper airplane.

In this way, the paper airplanes we folded, when they were still going out, rolled in the air a few times, and then fell to the ground in a swaying manner.

Only occasionally we fold paper airplanes, which slightly conform to some knowledge of aerodynamic principles, so that the paper airplanes we fold will row 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 principle of aerodynamics when designing, and only the aircraft designed as an "airplane" can fly in a balanced manner.

If you don't take aerodynamics into account, even if you design an airplane that looks like a real airplane, it won't fly.

The reason why the aircraft can fly steadily in the sky is because the shape of the aircraft is designed using the principles of aerodynamics, especially the wings, which are designed with this problem in mind.

And how did humans learn this knowledge, thanks to the birds that fly freely in the sky?

It is from the flight of birds that human beings learned the principles of aerodynamics, so they were able to develop high-altitude aircraft such as airplanes.

Birds are able to fly freely in the air precisely because their shape is completely aerodynamic.

It is from the flight skills of birds that humans have mastered the principles of aerodynamics, which allows human planes to soar in the sky.

Missiles developed by human beings must also conform to the principle of aerodynamics, otherwise, after being launched, the missile will only turn its head in the air and will not be able to attack the target.

In this respect, missiles are about the same as bullets.

When the bullets in the guns were fired, it was always difficult to shoot at the target, and the accuracy was very poor.

This is mainly due to the fact that the inside of the barrel of the original guns was smooth. After the bullet is fired out of the barrel, it is easy to create a huge friction force with the air due to its high speed.

The bullet is small and light, so that when the bullet is fired from the smooth barrel without rifling, it will turn over in the air.

Although people can't see bullets turning in the air with the naked eye. But theoretically, the bullet would have flipped in the air. This is especially true when the wind speed is relatively high.

Of course, people can now use high-speed cameras to see the trajectory of bullets fired from the barrel.

But in any case, the guns originally developed by mankind were very poor in accuracy, and it was difficult to hit distant targets.

Later, people used the principle of aerodynamics, and later people were inspired by small things like spinning tops, and knew that objects can maintain a relatively stable posture when they rotate.

So people thought about how to make the bullet out of the barrel of the gun with a rotating position, so that the bullet would not turn over.

Later, people came up with the idea of designing rifling in the barrel to solve the problem of bullets coming out of the barrel, continuing to rotate and fly, and maintaining a balanced flight state.

Later, almost all of the barrels of guns designed by people were rifled. Only such a gun is capable of having a high accuracy of shooting.

But the missile is a big thing, it can't shoot out of the barrel like a bullet, the missile is launched from the missile launcher.

During the flight, it is impossible to keep it in a rotating posture all the time. And if it can't rotate, how can it ensure the stability of the missile's flight at high altitude!

This is where the tail fins of the missiles are attached. The tail of the missile is a measure to keep the missile balanced in flight.

However, such measures can only solve the problem of the flight of ordinary missiles. Because the flight speed of missiles in general will not be too fast. At most double to double the speed of sound. Some can even fly at subsonic speeds.

Cruise missiles, for example, can fly at subsonic speeds at high altitudes, constantly changing their flight attitude so that the missile can accurately lock onto the target.

And the speed of ballistic missiles is very fast, almost a dozen times the speed of sound, and at such speeds, the role of the tail is not great. If you want the ballistic missile to remain balanced as it flies to the target, you have to think of something else. (To be continued.) )
