Chapter 629: A role model for young people, using discounts in exchange for actual combat materials
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 moment, all the information was distributed to everyone.
"Okay, has everyone got the information?"
After Wan Long led the people to leave, Su Dingping's eyes swept over everyone. Did he see anyone? After the person raised objections, he continued to lecture.
"Then let's start the class. I hope everyone will pay attention."
"Let's first understand the technical characteristics of ballistic missiles. I believe everyone knows something about it. It is in the information, so I won't go into details. ”
“I just want to be simple To put it bluntly, a ballistic missile is an offensive weapon that flies along a predetermined trajectory to attack fixed targets on the ground or water. It has a large take-off mass and volume, and a complex structure, but it has a strong ability to penetrate and attack multiple targets. It is advanced. The terminal guidance system can also improve the target Target strike accuracy!”
“Let me 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... …”
“ 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 and 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 clearly, 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 carried out 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 super military powers on Blue Star, namely the Eagle Tribe and the White Bear Tribe. This is to amplify the pace of the move.
Thinking of this, their emotions became excited.
But in order to have a better class, they concentrated immediately.
“A high-speed delivery track 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 specifically marked the active stage, free stage 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 gravity 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 gravity 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, and the velocity vector is sandwiched between the horizontal plane and the horizontal plane. The angle (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 motion..."
"We therefore We can summarize 12 sets of equations, and then there is an equation for the mass loss of the missile when it burns: Dm/Dt=mc, and three geometric relationship equations..."
Everyone below, young or old, all Everyone 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 the second page."
Su Dingping quickly wrote down the formulas and related key points while explaining, "In addition to the Acides equation, Lodos dynamics Equations... We also need to consider a series of issues such as the oblateness of the earth, ballistics, and guidance.”
"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, you are just getting started. How to fly and how to calculate the ballistic trajectory."
"The research on the follow-up warhead is also the warhead. , missile body structure, power plant, 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 in the middle to let someone go to the toilet.
Even in such a tense learning atmosphere, no one complained or complained, and they still listened attentively.
Especially those who are new here have almost completely forgotten the shock at the beginning and devoted themselves entirely to learning and understanding new knowledge.
Each of them knew very well that the opportunity for Su Dingping to give lectures was very rare, especially his explanations in simple and simple terms, combined with practical explanations, which made them fascinated.
Even Guo Xueyun calmed down his initial shock and listened carefully to the lecture and took notes, for fear of missing the relevant content that Su Dingping said.
For those young people, the talent displayed by Su Dingping deeply conquered them.
Next, whether they were newcomers or veteran military experts, Su Dingping quickly answered any questions they raised in a very concise and easy-to-understand manner.
This behavior has benefited everyone a lot.
Being able to explain incomprehensible issues clearly is perhaps the biggest difference between Su Dingping and those old military industry experts.
It is one thing to understand, but it is another thing to be able to explain it in a very concise language so that people with different knowledge levels can understand it. It can be said that this is also a skill.
Obviously, to everyone present, Su Dingping is someone who has this ability!
Time always flies by, especially for those who listen carefully. Several hours pass by in a flash.
"Okay, that's the end of today's class." Su Dingping raised his watch and looked at it, and then said seriously, "Next time, I will bring Mr. Qian's disciples over and give you another lesson. Give a detailed explanation.”
"If the opportunity is right, I will personally take you to see the Dark Sword 1 ballistic missile launch site and experience the actual combat application of ballistic missiles for yourself."
"Well, it won't take too long, or Worth looking forward to.”
Everyone was very excited when they heard the news. It was a rare opportunity to see the actual combat application of the Dark Sword One ballistic missile with their own eyes.
The Dark Sword No. 1 ballistic missile is an extremely advanced medium-range ballistic missile with huge 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 teaching room.
From the beginning to the end, Su Dingping did not follow the text in the lecture notes. Instead, he combined his own practice to give in-depth explanations and shared his research experience with everyone.
It even explained the most cutting-edge technology of current ballistic missiles, which directly forced everyone at 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 not pulling out for a long time.
For the first time, they felt that learning such advanced technologies and theories does not have to be so boring.
When Guo Xueyun finally understood the first knowledge point, he looked up and saw that Su Dingping was no longer in the classroom. He had obviously left the place.
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. She picked it up and looked at it carefully.
Inside the photo frame was a personal photo of Su Dingping, which she had taken by chance. It was a snapshot from the right angle, so it was naturally very clear.
Her hand gently brushed over the photo frame, and she stopped after a moment. Only then did Guo Xueyun carefully put it away and put it in the drawer.
I used to carry it with me everywhere and place it in the most eye-catching place to motivate myself to keep moving forward and follow in his footsteps. At the same time, I also hope that one day I can work hard to enter the mysterious integrated naval arsenal and become a colleague of Su Dingping.
Now, after learning the exact identity of Su Dingping, Guo Xueyun realized that the gap between the two was really too big and could not be bridged through hard work.
So, she could only bury that little thought deep in her heart.
She knew very well that in the eyes of ordinary people, she was so dazzling, a genius, an outstanding person with both beauty and wisdom, but she struggled to move forward among the geniuses.
And Su Dingping has become the object of countless geniuses to look up to, and he is also a role model for young people in the new era!
She has no way not to face this!
Late at night, Beijing Airport.
In the night, a special plane landed slowly, but the outside world knew nothing about it.
After getting off the special plane, the group quickly drove out of the airport in a special car that had been prepared and headed towards the city at a very fast speed.
About half an hour later, the convoy drove into a compound.
In a conference room in a building, representatives from the chiefs of the navy, army and air force gathered!
Opposite them were a group of senior generals from the Kayi 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 rearm the Keyi tribe. of the navy, army and air force.
After suffering a lot of hardships, they realized the importance of modern military thinking of joint operations between the sea, land and air forces. Naturally, they wanted all the equipment of the sea, land and air forces.
The secret talks between the two parties lasted for more than three hours. The final result was naturally that both parties were very satisfied, and the final moment of signing the agreement was quickly reached.
A Longxia tribe army chief glanced at the leader of the Keyi tribe next to him who was responsible for signing.
“Right now, your Kayi tribe is at a critical moment of reconstruction. Now you have to spend such a large amount of military expenditures to purchase equipment. Funds must be very tight, right?”
The leader of the Kayi tribe first said He was stunned for a moment, then nodded seriously.
"That's right. Our tribe is in a very bad situation right now. We need to spend money on everything. Naturally, funding is tight."
This matter is basically a public fact, and he naturally also There is nothing to hide.
It’s just that he didn’t understand what this dear friend meant, so he couldn’t help but have some expectations.
“Since this is the case, for the sake of our friendship and the continued military trade in the future, after some discussion, we decided to give you a 10% discount.”
“Of course, we are not responsible for infrastructure construction, so please understand.”
What? 10% off?
You heard that right? There is such a good thing?
They plan to spend 4 billion to purchase weapons and equipment for the three armed forces, which is equivalent to a sudden saving of 400 million US dollars.
For them, this is definitely not a small amount, it is simply a timely help!
The leader of the Kayi tribe was confused at first, but he was more moved.
Moved, the leader of the Kayi 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 head of the Air Force immediately He 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 that 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 these words, the leader of the Kayi tribe immediately fell into deep thought.
In the Kayi tribe war, they were indeed beaten very miserably. The million-strong army was almost completely lost, and the iron torrent was completely destroyed. However, a lot of actual combat data was left behind. For them, it seems that there is no What an effect.
