After Zhao Zhongyao selected the place where he wanted 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 Yan Mingcheng to build a simple test base on Shark Island within a month. Fortunately, he and some scientific researchers will go there to carry out the development and production of ballistic missiles in one month.

After hearing what Zhao Zhongyao said, Yan Mingcheng naturally went to do 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 blueprint of the ballistic missile.

Only with blueprints can the development of ballistic missiles be carried out!

Due to the complex structure and large size of the ballistic missile, Zhao Zhongyao also had to consult a lot of information before designing it.

Although Zhao Zhongyao was reborn from the relatively developed Huaguo before his death to this relatively backward Huaguo.

But he was a purely theoretical physicist before, and his research was mainly on nuclear physics.

Although many advanced weapons use the basic knowledge of physics, after all, doing basic research in physics is different from developing weapons and ammunition, which cannot be compared.

That is to say, 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 technology.

Otherwise, if he was asked to directly develop this ballistic missile, he might have no idea at all!

Fortunately, this time, he already had extensive experience in researching missiles. It will not be so difficult to study such a super weapon.

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.

For Zhao Zhongyao, he had only heard of ballistic missiles in his previous life. He doesn't know much about the real principle.

However, after all. He was also an old military fan in his previous life. He also knows a little about all aspects of military industry knowledge, and he also knows a little about this kind of ballistic missile weapon.

Now I want to develop this super weapon. 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 the missile is launched, it flies very high and at a very fast speed. When the missile finally hits the target, it can reach more than ten times the speed of sound.

At this speed, there is no weapon that can intercept it. In this high-speed flight. The missile itself has a lot of inertia. Even if an ordinary missile is successfully intercepted, it is difficult to completely destroy it.

What's more, at this speed, there are almost no missiles that can intercept it. After all, the speed is too fast. It is very difficult to intercept an extremely fast weapon at high altitude.

Although the extremely fast missile developed by Zhao Zhongyao before was already very fast, it was only six times the speed of sound. And this kind of ballistic missile can reach more than ten times the speed of sound when it finally attacks.

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 ballistic missiles can have a speed more than ten times the speed of sound when attacking the target. This is mainly because the missile is launched vertically. It has to fly to an altitude of a thousand kilometers above the ground, and then do horizontal flight.

Ballistic missiles can fly outside the atmosphere. There is very little air resistance there. so. Ballistic missiles can obtain a very fast initial velocity under the impetus of a developed machine.

And when the ballistic missile flies for a certain distance and is ready to attack the target on the ground, it will fly to the target from high altitude at a dive or even a vertical angle.

Ballistic missiles themselves are relatively large and weigh several tons.

Once such a big guy dives down from a high altitude, one can imagine the acceleration of gravity it obtains.

Driven by such a powerful acceleration of gravity, ballistic missiles can naturally reach more than ten times the speed of sound.

With such extreme speed. Of course there is no missile that can intercept it. It can also accurately aim at the target and destroy the target quickly.

Ballistic missiles are so powerful, but it is not an easy task to develop and produce such weapons.

After a month of hard work, Zhao Zhongyao finally drew the blueprint of this ballistic missile.

Then came to Shark Island with Yan Mingcheng. They are going to work on the development of ballistic missiles.

"Zhongyao, will we be able to develop this super weapon soon! By then, 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.

"It may be that we have already obtained the information! Country M is also researching this kind of ballistic missile now! Maybe it is even more powerful than ours!"

Zhao Zhongyao dare not speak big words now, after all. The strength of country m lies there! Now he dares to say that the ballistic missile he developed will definitely be better than that developed by Jonis, which is hard to say!

"Zhongyao, what's wrong with you, aren't you always very confident! Why, this time you don't have confidence

up. When Yan Mingcheng heard Zhao Zhongyao's words, he felt a little surprised!

"I do have confidence. But I don't want to talk big. Before I develop this kind of missile, how can I guarantee that the missile I developed will be more advanced than that developed by Jonis!

Only after this kind of missile is developed first, and then the test firing is carried out, can we know who developed the missile! "

Zhao Zhongyao was not a braggart in the first place. At such a critical moment, he naturally didn't want to talk nonsense.

"Zhongyao, you know, the missiles you developed before are all more advanced than those developed by Jonis! Why, this time, is the missile you developed really difficult! Why, you don't have the confidence you used to. ah!"

Yan Mingcheng was still a little strange, thinking, when Zhao Zhongyao was developing any kind of missile before, he was very confident, and he always said that the missile he developed must be better than that developed by Jonis! But this time, Zhao Zhongyao seemed not so confident.

"This, you don't 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 materials. He knew that ballistic missiles fly very fast, and there are high technical requirements for maintaining a stable posture first.

Previous missiles flew at low altitudes. As long as there is a powerful enough engine, the missile can fly very fast. 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 hit it.

However, this ballistic missile is completely different from the previous missiles. This missile mainly relies on altitude to win. Its orbit is basically determined before launch, and it will not change direction during the flight.

And the missiles developed before. For example, the cruise missile developed last time is different. This kind of missile can fly in the sky like an airplane, and can also change the direction of the missile according to needs.

The ballistic missile developed this time is different. It is a missile that flies according to a predetermined trajectory.

The speed of this missile is very fast when attacking, almost ten times the speed of sound. At such speeds, there will be strong friction between the missile's warhead and the air.

This kind of friction can make the warhead of the missile generate thousands of degrees of high temperature instantly.

At such high temperatures, any known metal on Earth could melt. If the warhead of the missile melts during flight, it will be dangerous. There is a good chance that the missile will not buy the location of the target. It has already detonated its own high temperature.

If this is the case, then this kind of missile does not need to hit the enemy's target, and it will be destroyed by itself.

Therefore, the first hurdle to pass in the development of this missile 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, next. There is one more problem!

It is the problem of how to maintain the balance of the missile during flight. We all know that when an object is flying at high speed in the air, it is very unstable. It is easy to roll over.

Just like the paper airplanes we folded when we were kids.

Just find a piece of paper. Folded into a paper airplane, and then went 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 we fold usually roll a few times in the air when they go out. It wobbled and fell to the ground.

Only occasionally, the paper airplanes we fold conform to some principles of aerodynamics, so that the paper airplanes we fold can travel a certain distance in the air with a more graceful posture.

The reason why the plane can fly stably in the sky is because the layman of the plane must fully consider the principle of aerodynamics when designing it. Only an aircraft designed as an 'aircraft' can be balanced in the air flight.

If you don't consider aerodynamic factors, even if you design an airplane that looks exactly like a real airplane, it won't be able to fly.

The reason why the plane can fly stably in the sky is because the shape of the plane is designed using the principle of aerodynamics, especially when the wings are designed, this problem is taken into consideration.

And how humans learned this knowledge, thanks to the birds flying freely in the sky!

It is from the flight of birds that humans have learned the principles of aerodynamics, so they can develop high-altitude aircraft such as airplanes.

The reason why birds can fly freely in the sky 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, which allows human aircraft to soar in the sky.

The missiles developed by humans also need to conform to the principle of aerodynamics, otherwise, after the missiles are launched, they will only turn somersaults in the air, and it is impossible to attack the target.

In this regard, missiles are similar to bullets.

When the bullets in the gun were fired, it was always difficult to hit the target and the accuracy was very poor.

This is mainly because the barrels of the original guns were smooth on the inside. After the bullet is fired from the barrel, due to its high speed, it is easy to generate huge friction with the air.

And the bullets are so small and light that they do somersaults in the air after being fired from a smooth, unrifled barrel.

Although people can't see the bullets turning somersaults in the air with the naked eye. But in theory, the bullet will definitely turn somersault in the air. This is especially the case when the wind speed is relatively high.

Of course, people can also see the flight trajectory of bullets fired from the gun barrel with high-speed cameras.

But no matter what, the guns originally developed by humans were very poorly aimed, and it was difficult to hit distant targets.

Later, people used the principle of aerodynamics, and later people were inspired by small things like gyroscopes, and they knew that when an object rotates, it can maintain a relatively stable posture.

So people think about how to make the bullets have a rotating posture when they are fired from the barrel, so that the bullets will naturally not turn over.

Later, people thought of the method of designing rifling in the barrel to solve the problem of bullets coming out of the barrel, continuing to rotate and flying, and maintaining a balanced flight state.

So later, the barrels of the guns designed by people are almost all rifled. Only such guns can have high shooting accuracy.

But the missile is a big thing, it cannot be shot out of the gun barrel like a bullet, and the missile is launched from the missile launcher.

During the flight of the missile, it is impossible to keep it in a rotating posture. If it cannot rotate, how can it ensure the flight stability of the missile in high altitude!

This will put the tail on the missile. The tail of the missile is a measure to keep the missile in balance during flight.

But this measure can only solve the flight problem of general missiles. Because the flight speed of general missiles will not be 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 subsonic speeds in high altitudes and constantly change their flight attitude so that the missiles can accurately lock the target.

The speed of ballistic missiles is very fast, almost ten times the speed of sound. At such speeds, the effect of the tail is not great. If you want to keep the ballistic missile in a balanced state while flying to the target, you need to think of some other clever tricks.
