Chapter 629: A role model for young people, using discounts to exchange for practical information

When these people were still studying conventional missiles, Su Dingping had already begun to guide them to study the more advanced field of ballistic missiles!
In a short while, all the information was distributed to everyone.

"Okay, has everyone got the information?"

After Wan Long and his men left, Su Dingping glanced at everyone. Seeing that no one raised any objections, he continued his lecture.

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

"Let's first learn about the technical characteristics of ballistic missiles. I'm sure everyone has some understanding of them. They are in the information, so I won't go into details."

"I will just briefly explain that a ballistic missile is an offensive weapon that flies along a predetermined trajectory to attack fixed targets on the ground or surface. It has a large takeoff mass and volume, and a complex structure, but it has a strong ability to penetrate and strike multiple targets. The advanced terminal guidance system can also improve the accuracy of target strikes!"

"Let me mention here that in addition to attacking fixed targets on the water surface, ballistic missiles can also attack moving targets on the water surface. As for how to attack moving targets, we will talk about it later..."

"Its 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, the ground equipment is complex, and it cannot meet the requirements of modern combat use."

"The Eagle Tribe's militia ballistic missiles have high accuracy..."

Although it was not stated explicitly, this reminder made everyone below, even those veteran military experts, open their eyes wide.

They had also heard that during the Soviet era, ballistic missiles were used to hit moving surface targets, that is, to attack warships, but they failed for various reasons, proving that this approach was not feasible.

I specifically mention this today. Could it be that Su Dingping has already started research in this area and achieved certain results?

At the very beginning, the accuracy of the intercontinental ballistic missiles of the Eagle Tribe and the White Bear Tribe, the two most important super military powers on the blue planet, was mentioned. It seems that they are about to release a big move.

Thinking of this, their emotions became excited.

However, in order to have a better class, they immediately focused their attention.

"A high-speed launch 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..."

Speaking of this, Su Dingping picked up the chalk and drew several ballistic parabolas on the blackboard, and specially marked several flight phases such as the active phase and the free phase.

"In the active phase, the forces acting on the missile include engine thrust, aerodynamic force, control force, which is mainly generated by swinging the engine nozzle or manipulating the control surfaces, and the earth's gravity. Among them, engine thrust plays the main role."

"The Earth's perturbed gravity (or gravity anomaly) is the deviation of actual gravity from standard gravity, which is caused by the uneven distribution of mass inside the Earth. The acceleration caused by the Earth's perturbed gravity is about a few hundredths of a centimeter per second squared (tens of milligal), and the impact on the accuracy of the impact point of an intercontinental missile is about 1 kilometer."

"Therefore, this force cannot be ignored, especially for intercontinental ballistic missiles. The longer the range, the more it needs to be considered!"

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

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

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

"The calculus equation for the active phase of a ballistic missile...where m is the mass of the missile and v is the instantaneous velocity of the missile: v = vx2 + vy2."

"...Of course, things like that, including force, damping control, rotation, and center of mass motion..."

"We can therefore summarize 12 sets of equations, and then there is an equation for the mass loss of a missile when it burns: Dm/Dt=mc, and three geometric relationship equations..."

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

It didn't take long before Su Dingping wrote down two full blackboards of formulas and various deduction processes while explaining.

Looking at so many formulas, everyone felt overwhelmed!
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 quickly wrote down the formulas and related key points while explaining, "In addition to the Archides equation and the Lodoss dynamic equation... we also need to consider a series of issues such as the Earth's oblateness, trajectory, and guidance."

"Ballistic missiles are very complex. We need to understand this and study hard."

"Of course, your understanding of the calculation formula is just the beginning. You need to understand how it flies and how to calculate its trajectory."

"The subsequent warhead research, including the warhead structure, power plant, guidance system, etc., are all challenges that need to be overcome step by step."

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

This lecture seemed like it could not be stopped and lasted for several hours, with only a ten-minute break in the middle for the audience to go to the toilet.

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

Especially those newcomers, they almost completely forgot the initial shock and concentrated on learning and understanding the new knowledge.

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

Even Guo Xueyun suppressed her initial shock and listened to the class carefully and took notes, fearing that she would miss out on any relevant content that Su Dingping was talking about.

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

Next, no matter whether they were new or old military experts, Su Dingping gave quick answers to any questions they raised in a very concise and easy-to-understand manner.

This behavior has benefited everyone a lot.

Being able to explain profound and mysterious issues clearly is perhaps the biggest difference between Su Dingping and those veteran military experts.

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

It is obvious to everyone present that Su Dingping is the one who possesses this ability!

Time always flies quickly, especially for those who listen carefully. A few hours go by in a flash.

"Okay, that's all for today's class." Su Dingping looked at his watch and said seriously, "Next time, I will bring Mr. Qian's students here 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 ballistic missiles in person."

"Well, this time won't be too long, it's still worth looking forward to."

Everyone was very excited to hear the news. It was truly a rare opportunity to see the actual combat application of the Dark Sword-1 ballistic missile with their own eyes.

The Dark Sword No. 1 ballistic missile is an extremely advanced medium-range ballistic missile with enormous 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, turned around and strode out of the classroom.

From beginning to end, Su Dingping did not just read out the contents of the lecture notes, but instead combined his own practice to give in-depth and easy-to-understand explanations, and also shared his research insights with everyone.

He even gave a brief explanation of the most cutting-edge technology of current ballistic missiles, which directly brought everyone present to the forefront of ballistic missile research.

Even after Su Dingping had left for a long time, everyone was still immersed in the ocean of knowledge, enjoying the learning process and not being able to pull themselves 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 just finished understanding the first knowledge point, looked up, she saw that Su Dingping was no longer in the classroom. It was obvious that he had left.

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

Inside the photo frame is a personal photo of Su Dingping, which she took by chance. She chose the right angle to capture the photo, so it is naturally very clear.

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

I used to carry it with me wherever I went, and put it in the most conspicuous place, naturally to motivate myself to keep forging ahead and follow in his footsteps. At the same time, I also hoped that one day I could work hard to enter the mysterious naval integrated military factory and become Su Dingping's colleague.

Now, after learning Su Dingping's exact identity, Guo Xueyun realized that the gap between them was too big and it could not be made up through hard work.

So, she could only bury that little thought deep 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.

Su Dingping has become the object of admiration for countless geniuses, and is also a role model and example for young people of the new era!
There was no way she could ignore this!
Late at night, Beijing Airport.

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

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

After about half an hour, the convoy drove into a large courtyard.

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

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

The reason why they traveled thousands of miles to the Longxia tribe 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 Keyi tribe's navy, army and air force.

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 that lasted more than three hours. Naturally, both sides were very satisfied with the final result, and they soon reached the final moment of signing the agreement.

A Longxia tribal army chief glanced at the leader of the Keyi tribe who was in charge of signing.

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

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

"That's right. Our tribe is in a very bad situation right now. We have a lot of work to do and need to spend money everywhere. Naturally, our funds are tight."

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

But he didn't understand what this gentleman meant, so he couldn't help but feel a little excited.

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

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

What? 10% off?

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

They planned to spend 4 billion to purchase weapons and equipment for the three armed forces, which was equivalent to saving 400 million US dollars.

For them, this is definitely not a small amount of money, it is like a timely help!

The leaders of the Keyi tribe were stunned at first, but were more moved.

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

The Air Force chief immediately smiled and said, "No, no, our conditions are very simple and we won't make it difficult for you."

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

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

After hearing these words, 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.
