Rebirth of the Military Industrial Overlord

The hall was so quiet that needles fell.

Tan Zhenhua’s problem reconstructed the Shangganling battlefield from another angle. 43 years ago, Van Vleet obviously did not have such a weapon in his hands. Therefore, he could only use the existing resources on hand to focus on the target area and send it enough to load humanity. The artillery shells and aerial bombs in the history of war, but these did not help him effectively complete the combat goals, can it be changed to today?

"Dr. Tan, do you think that the weapons you hypothesized already exist today?" The person who asked the question was Ding Wei, the teacher of the "Tiger Master".

As the supreme commander of the "Red Army" in the "Confrontation 1995" exercise, although he stayed in the "Blue Army" headquarters and watched the whole process after the battle really started, this "overview" made Ding Wei feel that , This is more than what he actually gained from commanding the "Red Army" battle!

"I don't know." Tan Zhenhua replied frankly: "I haven't been to the U.S. for a long time, so my intelligence sources have been greatly restricted, and I cannot accurately understand the current situation of the development of various weapons of the U.S. Army. "

After a pause, he changed his words: "But I can be sure of one thing. A similar bomb must have been or is being developed by the Mi Army, and it may not be long before we learn of its existence."

"Dr. Tan, how can you be so sure?" Ding Wei asked, "Based on the requirements for this bomb you just said, how do I feel that it sounds like a little bit of science fiction?"

"This is definitely not science fiction."

Tan Zhenhua replied categorically: "And I can prove it."

"how to prove?"

"Of course I used the formulas of mathematics, physics and chemistry. My mother once taught me to learn mathematics, physics and chemistry, and I am not afraid to travel around the world.

"Uh……"

Even on such a serious occasion, someone could not help but chuckle a few times. Tan Zhenhua looked around the venue and nodded and said, “It seems that many people don’t believe me very much. Well, I’ll prove it on the spot. Look everyone."

There is no shortage of chalk on the blackboard in the meeting room. Tan Zhenhua does what he says, rolls up his sleeves and starts writing and drawing on the blackboard——

"Suppose: an explosive device is designed to be launched by a carrier. The mass of the explosive device is 2200 kg. The carrier will drop it at a speed of 800 kilometers per hour and a height of 10,000 meters. When the explosive device is separated from the carrier, the gravitational potential energy it has is calculated The formula is EP=mgh, where m is the mass and g is the acceleration due to gravity. To simplify the calculation, the approximate value is 9.8N/kg, and h is the height of the object from the horizontal plane. After calculation, the explosive device has an initial potential energy of 215.6 million Joules. , Let’s record this number first and put it aside for now."

The chalk scribbled across the blackboard. If some of the senior generals in the room had some understanding, some were still ignorant, and Tan Zhenhua's calculations continued.

"In addition to potential energy, because the explosive device has the same speed as the carrier aircraft due to the effect of inertia when it is separated from the carrier aircraft, it also has kinetic energy. According to the kinetic energy calculation formula Ek=mv²/2, where m is the mass, V is the moving speed of the object. After calculation, the initial kinetic energy of the explosive device is 54320987 joules. We will also write down this number."

"According to the law of conservation of energy, energy does not disappear out of thin air but only transforms between various forms. Therefore, we can think that the sum of the initial energy of the explosive device is the sum of the initial potential energy and the initial kinetic energy. The total energy is 269920987 joules."

After calculating this, Tan Zhenhua turned around and explained to all the audience: "The number obtained by calculation may not be intuitive enough for you to understand. Then I will convert it again. It is known that 1 gram of standard TNT The energy released when the explosive explodes is about 4200 joules. What is the energy of this explosive device? It is about the same as the energy released by the explosion of 64.5 kg of TNT explosive!"

Speaking of this, most people have already wondered about the taste, and some people have begun to whisper to each other. Tan Zhenhua announced his calculation results: "After calculations, we learned that the explosive device has a considerable value at the moment it leaves the carrier. Big total energy, what kind of result will this energy lead to? The result is that after it overcomes air resistance and reaches the ground through 10,000 meters of air, it can still penetrate 30 meters of ordinary sandy soil. Or directly penetrate 6 meters thick reinforced concrete!"

The voice of the discussion increased in vain, but Tan Zhenhua was unmoved and announced the final conclusion loudly: “Going back to our first question, the limestone with an average thickness of 35 meters above the No. 1 tunnel is made of calcite. The main component of carbonate rock, the main chemical component is CaCO3, and sometimes contains dolomite, clay minerals and detrital minerals. The hardness is generally low and easy to dissolve. Therefore, stone forests and karst caves are easily formed in limestone areas, which are usually called in geography. It is called "karst terrain". Friends who have been to Guilin should be familiar with this type of terrain. Tunnel No. 1 is such a natural cave structure-but this structure has a lower hardness than ordinary sand and gravel soil. Said that the resistance to this explosive is even smaller. It is entirely possible that it will pass through the 35-meter-thick rock layer and reach the inside of Tunnel 1. Everyone, you can imagine the consequences of that!"

This is really, as Tan Zhenhua said before, there is no shortage of mathematical, physical and chemical formulas, they are all used!

After a moment of silence, there was a "boom", and the meeting room seemed to be boiling, and all kinds of discussions became a whole!

General Liu had to knock on the table and shouted loudly: "Quiet, give me a quiet, what is it like? Where have you learned so many years of discipline education? You can ask questions one by one. !"

After all, they are all soldiers. With such a cry, Admiral Liu immediately suppressed everyone’s discussion. They raised their hands to show that they had something to say. Tan Zhenhua looked at the hand of Ru Lin raised in front of him and smiled. To Ding Wei.

Ding Wei stood up and asked: "Dr. Tan, I have been checking with your formula just now. There is no error in your calculation process, but this is only theoretical. We assume that the bomb you just mentioned is real, but it must To achieve the final goal of drilling into the tunnel, it is not enough that it is theoretically feasible. There are still many objective problems that need to be solved, such as how to accurately cast this explosive device to a suitable position to ensure that it can drill into the tunnel; How to ensure that this explosive device will explode after drilling into the tunnel, because it explodes early or late, it may not have the desired effect."

Tan Zhenhua nodded and said: "Mr. Ding, your question is very good, but you have missed a key point. Let me help you ask. This explosive device needs to constantly interact with the stratum when it penetrates the ground. Friction, so how can we ensure that its structure will not be damaged in the process."

Calm was restored in the conference room, and everyone understood that since Tan Zhenhua knew that these questions were the key, and he acted so confidently, it meant that he must have the answer in his heart!
