The interception of ballistic missiles requires a huge amount of calculations, predicting the trajectory and impact point based on the trajectory of the target, and calculating the best interception point based on one's own position and the range of the interceptor missile, etc. After these calculations are completed,

Determine the right time, launch the missile, and intercept!

The last time we shot down a satellite in space, we knew the trajectory in advance, so we could intercept it calmly. But now, everything is unknown. In a real simulated actual combat, the situation is more urgent, and it also tests the performance of the system.

Yes, the main thing is to test the system. People can't play a big role at this time. All calculations are systematic. People are only responsible for selecting the best one from several suitable trajectories and then launching the missile.

"Red flag-19 power-on self-test!"

"Launch cover open!"

Orders were issued quickly, and the atmosphere on the entire bridge was tense but calm.

Qin Tao stood on the bridge and looked at the launch device in front of the bridge. This time it was launched from the front, so the launch scene could be seen from the bridge. However, the cold launch was not as spectacular as the hot launch.

Small missiles are suitable for thermal launch. For example, the Hongqi-16 can dive directly to attack the target after coming out of the launch tube. However, large missiles are generally cold-launched. Large missiles such as the YJ-18 are thermally launched.

There are only a few other large missiles, such as Changjian-10 and Haihongqi-9, which are all cold-launched.

"The interception trajectory has been calculated, and there are three options!" At this time, another report came.

Three plans have been hung up on the big screen on the wall. Among them, the best plan is red, and the other two are green. The three plans give three different interception points. As for which one is the best...

It is better to trust your own judgment than to trust the computer program.

"Choose the first interception option!"

"The first interception plan! The interception data has been entered into the missile!"

"There are still ten seconds until launch, countdown starts now!"

"Three, two, one, launch!"

The missile launcher was enjoying himself again. As his finger pressed the button, there was a loud bang at the front of the ship's bow, and the missile flew out of the launch tube, and at the same time some gas was released.

"When you see this gas, you know it is our secondary piston ejection device." Qin Tao said.

Although they are all cold launches, cold launches are also particular.

For details, please refer to the heartless cannon. In many movies, the shooter only needs to stuff the explosive package into the oil barrel, then light it, and with a bang, the explosive package will fly out.

Why do explosive packets fly out? Do you rely on the director to use Qigong?

The real heartless cannon has a two-layer structure. First, a propellant pack is inserted, and a disc wooden baffle as big as the oil drum is placed in the middle. An explosive pack is placed on top, and the lead of the explosive pack must be inserted into it.

Go below.

In this way, the propellant package below is ignited, the propellant package generates gas, and the baffle is pushed. The baffle can push the explosive package in front to fly out. At the same time, the fuse of the explosive package is also ignited, and then it flies through a line in the air.

Arc, falling on the enemy's head, and exploded with a bang.

Putting the heartless cannon upright is similar to this cold-firing launcher.

The missile can fly out, of course, because it is squatting on the baffle. Below the baffle is a gas generator. When you need to launch the missile, start the gas generator, generate gas, push the baffle upward, and the baffle pushes the missile.

, push the missile out of the launch tube and fly into the sky.

However, there are still many problems with traditional cold launch devices. The baffle does not always push the missile to accelerate. As it moves upward, the pressure of the gas becomes lower and lower, and the acceleration of the baffle also begins to decrease. When the baffle moves

At about half the length of the launch tube, it no longer plays the role of pushing the missile forward. Here, the baffle will hit the buffer and separate from the missile.

As the launcher lengthens, this flaw will become more and more obvious. Specifically, it is similar to the problem faced by steam catapults.

Can it increase the energy of the gas generator?

This energy can be increased, but if the energy is increased, the thrust at the moment of ignition will be too large, which will increase the overload of the missile and affect launch safety.

So, how to solve this problem?

In order to make the nine-meter-long launch tube work normally, relevant technical personnel developed a two-stage ejection method, which perfectly solved this problem.

If the air pressure is too small, it will become weak in the second half. If the air pressure is too high, it will be unbearable at the beginning. Therefore, we simply changed it to a two-stage cylinder. The piston areas of the two-stage cylinders are different!

When it just started working, the pressure of the gas was very high. It first entered the first-stage piston cylinder mechanism. The area of ​​the first stage was small, so the pressure generated was not very large. It could push the missile up smoothly. By the time it reaches about one-third of the time,

At about a height, as the volume of the air chamber of the first-stage cylinder becomes larger and larger, the pressure becomes lower and lower. At this time, the high-pressure gas enters the second-stage piston cylinder mechanism through the air inlet on the cylinder. This

The piston area of ​​the second stage is larger, so even if the air pressure has been reduced, the thrust is still large enough.

To put it simply, it is the basic formula, F=P*S. The pressure is equal to the pressure multiplied by the action area. At first, when the pressure is high, use a small area. Later, when the pressure is low, use a large area. In this way, during the entire cold launch process, the launch

The device can push the missile to continue to rise, so that it rises to the top, and the whole process is doing work.

For this kind of large missile, the thrust force is not enough, and it really can't be fired. The nine-meter-long launch tube is unique to Dongfang and the only one in the world. Only Dongfang can solve this kind of launch tube technology.

At the same time, there are other changes to the ejection device of the secondary cylinder, such as the way the gas is discharged. Originally, it only opened a hole at the tail of the ejection cylinder. When the piston reaches the corresponding position, the gas begins to be released. Now it is changed to the piston being completely flushed out.

After the top of the cylinder, it is released from the gap between the piston and the cylinder, thus greatly improving the work efficiency.

This chapter is not over yet, please click on the next page to continue reading the exciting content! This also means that you can determine what kind of launch device it is by looking at the overflow of gas during launch. However, only experts can know.

As the double-stage cylinder ejected, the huge Hongqi-19 missile left the launch tube and continued to rise toward the sky. Li Pingfan looked at the missile with bright eyes, preparing to issue the next order.

During a cold launch, what should I do if the missile ejects but does not ignite?

In the past, the briquette launching device was tilted to the outside, so that if there was no ignition, it could fall directly into the sea water, but the current launching device does not work. The chocolate launching device is vertical and cannot be tilted, otherwise it will hit the bottom.

.

If there is no ignition, then quickly use full left rudder! The missile is dead, but the person is alive. This is also the reason for choosing to use the front launcher, so you can see clearly.

However, this kind of thing did not happen. After the missile jumped upward, a flame appeared from the tail, and then accelerated upward!

Launch successful!

The guys didn't shout excitedly. After all, unlike the YJ-18 launched last time, this time it was an attack. It not only had to be launched, but it also had to hit the target!

A new bright spot appeared on the big screen, climbing upwards, and the bright spot of the target was also flying towards it. At this moment, Qin Tao had an illusion that he was not in a warship, but in a satellite launch center.

The Satellite Launch Center in Qiongzhou also has such a scene, except that the screen is bigger and the space is larger, but now, even if the space is smaller, the feeling is the same.

We who build warships also want to engage in aerospace?

This illusion only lasted for a few seconds before Qin Tao heard the report.

"The first stage of the rocket fell off, reaching a speed of 1,500 meters per second!"

"The second stage rocket ignites and the speed increases further!"

Is this really a good idea to launch a rocket? Only rockets have first and second levels!

If a missile wants to reach a high enough speed, it must find ways to reduce its own weight. In this, there is a very important basic law. The easiest way to reduce its own weight is to throw away the useless shell. This is modern

The basic idea of ​​​​air defense missiles.

Take Hongqi-9 as an example. It only has a single-stage rocket, which will fall off completely after burning out. The shutdown speed is only 1,800 meters per second. When it comes to Hongqi-9B, it uses a two-stage design, and the outer shell is changed from steel to fiberglass composite material.

The shutdown speed has been increased to three thousand meters per second, so the combat distance has increased several times.

However, this speed is still not enough for anti-missile missions. Therefore, in the development from Red Flag 9 to Red Flag 19, many advanced technologies were used, such as more powerful solid propellants, carbon fiber composite materials for the outer casing, etc.

, such a two-stage rocket engine can push the missile to a higher speed.

Moreover, the fragmentation warhead was originally used. In order to obtain the largest killing radius, the weight of the warhead was as high as hundreds of kilograms. After using the kinetic warhead, no explosives were needed, and the weight was reduced to dozens of kilograms, so the range was natural.

Just further.

"The second stage rocket shuts down, speed is four thousand meters per second!"

"The kinetic energy warhead and projectile are separated!"

"The kinetic energy warhead is flying according to the predetermined orbit!"

On the screen, the two bright lines were getting closer and closer, and everyone held their breath.

The bright line on the screen seems to be still following its original trajectory. In fact, many numbers in the floating frame on the 19th bright spot of the Red Flag are beating rapidly, which means that this kinetic energy warhead is constantly adjusting its attitude.

Prepare for the final precise collision.

Back then, someone proudly claimed to have shot down a fly in space. In fact, it was just using a nuclear bomb to destroy a nuclear bomb, which was a lose-lose act. But now, using a kinetic warhead for precise impact is the real hit in space.

Mosquitoes in!

The airspace they are flying in is outer space, and they are rapidly approaching, approaching.

Suddenly, other electromagnetic waves also hit this side, and then more electromagnetic waves began to gather!

There’s a new audience!

However, the kinetic energy warhead did not panic because of the bystanders. It was still flying correctly according to the trajectory it had set before. It continued to adjust its posture, and finally met the thing flying from the opposite direction, and then slammed into it.

!

There is no air in space, so the sound of impact cannot be transmitted. There is no scattering of light in space. Therefore, the light caused by the collision only lasts for a moment. It is as if nothing happened in space and it is still quiet. Only some debris flies into the atmosphere.

Then it turns into a shooting star.

"Success!"

"Success!"

On board 055, everyone shouted excitedly.

"Turn on the satellite communication system immediately, we want to report the good news to the capital!" Li Pingfan said excitedly.
