I built an armada

While they were still studying conventional missiles, Su Dingping had already begun to guide them to study the more advanced field of ballistic missiles!

In a matter of seconds, all the information was distributed to everyone.

"Okay, has everyone got the information?"

After Wan Long led the people away, Su Dingping glanced at everyone. When he saw that no one raised any objections, he continued to lecture.

"Then we will start class. I hope everyone will pay attention."

"Let's first take a look at the technical characteristics of ballistic missiles. I believe everyone knows it to some extent. It is in the information, so I won't go into details."

"I will just briefly say that ballistic missiles are offensive weapons that fly along a predetermined trajectory to attack fixed targets on the ground and water. They have large take-off mass and volume, and complex structures, but they have powerful capabilities to penetrate defenses and attack multiple targets. capabilities, the advanced terminal guidance system can also improve target strike accuracy!”

"I would like to mention here that in addition to attacking fixed targets on the water, ballistic missiles can also attack moving targets on the water. As for how to attack moving targets, we will leave it to you later..."

"The guidance methods include radio command guidance, inertial guidance, starlight-inertial guidance, etc. Radio command guidance is the guidance method used by early ballistic missiles. It is susceptible to radio interference, has complex ground equipment, and cannot meet the requirements of modern combat use."

"The hit accuracy of the Eagle Tribe's militia ballistic missiles..."

Although it was not stated explicitly, this reminder made everyone below, even the veteran military industry experts, widen their eyes.

They had also heard before that during the Soviet Union period, ballistic missiles were used to hit moving targets on the water, that is, to attack warships. However, they failed due to various reasons, proving that this path was unworkable.

I would like to mention it today. Could it be said that Su Dingping has already conducted research in this area and achieved certain results?

At the beginning, we talked about the hit accuracy of the intercontinental ballistic missiles of the two most important superpowers on Blue Star, namely the Eagle Tribe and the White Bear Tribe. This is to amplify the pace of the attack.

Thinking of this, their emotions became excited.

But in order to attend class better, they immediately concentrated.

"A high-speed delivery trajectory is particularly important for ballistic missiles. The trajectory of the missile's center of mass in space is called the trajectory. The trajectory of a two-stage ballistic missile..."

Having said this, Su Dingping picked up the chalk and drew several ballistic parabolas on the blackboard, and specially marked the active phase, free phase and other flight stages.

"In the active section, the forces acting on the missile include engine thrust, aerodynamic force, control force, which are mainly generated by swinging the engine nozzle or control surface, and there is also earth's gravity. Among them, engine thrust plays a major role."

"The Earth's gravitational disturbance (or gravity anomaly) is the deviation of the actual gravity from the standard gravity, which is caused by the uneven distribution of mass inside the Earth. The acceleration caused by the Earth's gravitational disturbance is about a few hundred centimeters per square second (tens of milligal), the impact on the impact accuracy of intercontinental missiles is about 1 km.”

"Therefore, this force cannot be ignored, especially for intercontinental ballistic missiles. The farther the range, the more you need to consider!"

"Under the action of these forces, the missile's flight speed, flight altitude and flight distance gradually increase, while the angle between the speed vector and the horizontal plane (the ballistic inclination angle) gradually decreases."

Su Dingping turned around and pointed at the drawn active segment flight parabola to explain.

Next, he quickly wrote a long list of calculation formulas on the blackboard.

"The calculus equation of the active section of a ballistic missile...where m is the mass of the missile, v is the instantaneous velocity of the missile v=vx2+vy2."

"...Of course, and so on, including force, control damping, rotation, center of mass movement..."

"We can therefore summarize 12 equations, and then there is an equation for the missile's mass loss when burning: Dm/Dt=mc, and three geometric relationship equations..."

Everyone below, young and old, was listening attentively while frantically taking notes with the pens in their hands.

It didn't take long for Su Dingping to explain, while recording two full blackboard formulas on the blackboard, as well as various overturning processes.

Seeing so many formulas, everyone felt dizzy!

But this is just an appetizer.

Next, Su Dingping pushed the second blackboard upwards, and then started writing on the third blackboard.

"Please turn to page two."

Su Dingping explained while quickly writing formulas and related key points, "In addition to the Acides equation and the Lodos dynamic equation... we also need to consider a series of issues such as the oblateness of the earth, ballistics, guidance, etc."

"The complexity of ballistic missiles is quite high. Everyone needs to establish this understanding and study hard."

"Of course, if you understand the calculation formula, it's just an introduction. You know how to fly and how to calculate the ballistic trajectory."

"The follow-up research on the warhead, that is, the warhead, the missile body structure, the power plant, the guidance system, etc. are all difficulties that must be overcome step by step."

"There are also differences between ballistic missiles and conventional missiles..."

This lecture seemed to be unstoppable and lasted for several hours, with a ten-minute break for people to go to the toilet.

Even in such a tense learning atmosphere, no one complained, they still listened attentively.

Especially those newcomers, they almost completely forgot the shock at the beginning, and devoted themselves to learning and understanding new knowledge.

Each of them knew that the opportunity of Su Dingping's lecture was very rare, especially his in-depth and easy-to-understand explanations combined with practice, which made them fascinated.

Even Guo Xueyun restrained the initial shock and listened to the lectures carefully and took notes, fearing that he would miss the relevant content of Su Dingping's talk.

For those young people, the talent shown by Su Dingping deeply conquered them.

Next, no matter those newcomers or those old military experts, Su Dingping gave quick answers to any questions they raised in a very concise and easy-to-understand way.

This behavior benefited everyone a lot.

Being able to explain profound and mysterious problems clearly, perhaps this is the biggest difference between Su Dingping and those old military experts.

Understanding is one thing, and being able to explain it in very concise language so that people with different knowledge reserves can understand it is another thing. It can be said that this is also a skill.

Obviously, for everyone present, Su Dingping is obviously a person with this ability!

Time always flies fast, especially for those who listen carefully. A few hours have passed in a flash.

"Okay, today's class ends here."

Su Dingping raised his watch and glanced at it, then said seriously, "Next time, I will bring Qian Lao's disciples to give you a detailed explanation."

"If the opportunity is right, I will personally take you to see the launch site of the Dark Sword No. 1 ballistic missile and experience the actual combat application of the ballistic missile in person."

"Well, this time will not be too long, it is still worth looking forward to."

Hearing this news, everyone was very excited. It is really a rare opportunity to see the actual combat application of the Dark Sword No. 1 ballistic missile with their own eyes.

The Dark Sword No. 1 ballistic missile is an extremely advanced medium-range ballistic missile with great power!

It is said that more models are being developed based on this ballistic missile. They feel that they have come to the right place.

After Su Dingping finished speaking, he put away his handbag and turned around and walked out of the lecture room.

From beginning to end, Su Dingping did not read out the contents of the handouts, but combined his own practice to give a simple and in-depth explanation, and also shared his research experience with everyone.

He even explained the most cutting-edge technology of current ballistic missiles, which directly pulled everyone on the scene to the forefront of ballistic missile research.

Until Su Dingping left for a long time, everyone was still immersed in the ocean of knowledge, enjoying the learning process, and did not pull out for a long time.

For the first time, they felt that learning such advanced technology and theory did not have to be so boring.

When Guo Xueyun, who had finally mastered the first knowledge point, looked up, she saw that Su Dingping was no longer in the lecture room, and it was obvious that he had left here.

After finishing all the work, she returned to the single dormitory and sat in front of the desk. She saw the photo frame placed in the upper left corner. She picked it up and looked at it carefully.

Inside the photo frame was a personal photo of Su Dingping, which she took by chance. The angle of the photo was chosen correctly, so it was naturally very clear.

Her hand gently brushed over the photo frame, and she stopped after a moment. Guo Xueyun then carefully put it away and put it in the drawer.

In the past, she carried it with her everywhere and placed it in the most eye-catching place, naturally to motivate herself to keep moving forward and follow his footsteps. At the same time, she also hoped that one day she could enter the mysterious naval integrated military factory through hard work and become Su Dingping's colleague.

Now, after learning the exact identity of Su Dingping, Guo Xueyun realized that the gap between the two was too big and could not be made up by hard work.

So, she could only bury that little thought deeply in her heart.

She knew very well that she was so dazzling in the eyes of ordinary people, a genius, an outstanding person with both beauty and wisdom, but she was struggling to move forward among a group of geniuses.

And Su Dingping has become the object of admiration of countless geniuses, and even more a role model and model for the youth of the new era!

She had no way to ignore this!

Late at night, Beijing Airport.

In the night, a special plane slowly landed, but the outside world knew nothing about it.

After getting off the special plane, the group took the special car that had been prepared long ago and drove out of the airport quickly, heading towards the city at a very fast speed.

About half an hour later, the convoy drove into a large courtyard.

In a conference room in a building, representatives of the heads of the navy, army and air force gathered!

Opposite them were a group of senior generals from the Keyi tribe wearing different military uniforms, as well as some military experts.

The reason why they came to the Longxia tribe from thousands of miles away was, on the one hand, for the reconstruction plan of the Keyi tribe, and on the other hand, to purchase a batch of arms and equipment from the Longxia tribe to re-arm the navy, army and air force of the Keyi tribe.

After experiencing many hardships, they realized the importance of modern military thinking of joint operations of the navy, army and air force, and naturally they wanted all the equipment of the three services.

The two sides held a secret meeting for more than three hours. The final result was naturally very satisfactory to both parties. Soon they came to the moment of signing the agreement.

A Longxia tribe army chief glanced at the leader of the Keyi tribe who was responsible for signing.

"Right now, your Keyi tribe is at a critical moment of reconstruction. Now you have to spend such a large amount of military funds to buy equipment. I guess the funds are very tight, right?"

The leader of the Keyi tribe was stunned for a moment, and then nodded seriously.

"That's right. Our tribe is in a very bad situation now. There are many things to be rebuilt. We need to spend money everywhere. Naturally, the funds are tight."

This matter is basically an open fact, and he naturally has nothing to hide.

But he didn't understand what this gentleman meant, so he couldn't help but look forward to it.

"Since this is the case, for the sake of our friendship and the continuous military trade in the future, we have decided to give you a 10% discount after some discussion."

"Of course, infrastructure is not our responsibility, please understand."

What? 10% discount?

Did I hear it right? There is such a good thing?

They are going to spend 4 billion to buy weapons and equipment for the three armed forces, which is equivalent to saving 400 million US dollars.

For them, this is definitely not a small amount, it is simply a timely help!

The leader of the Keyi tribe was stunned at first, but more moved.

In addition to being moved, the leader of the Keyi tribe immediately said: "I don't know what your requirements are, please tell me. If the conditions are too harsh, I think we are still willing to buy without discounts."

The Air Force chief smiled and said: "No, no, our conditions are very simple and will not embarrass you."

"We have only one condition, we hope you can provide all the detailed information from the last war."

"Whether it is yours or the coalition led by the Eagle Tribe."

After hearing this, the leader of the Keyi tribe immediately fell into deep thought.

In that Keyi tribal war, they were indeed defeated very badly, their million-strong army was almost wiped out, and their iron torrent was completely destroyed. However, a lot of actual combat data was left behind, which did not seem to be of much use to them.
