Chapter 18 Calculation
"A fierce battle?"
Lin Li touched his chin, with a slightly solemn expression on his face.
Ma Ning clasped his hands behind his back and said slightly confidently:
“The possibility of a fierce battle is very high, and both sides seem to be well prepared.
After all, if it was really a losing battle, those families in the city might have abandoned the city and fled long ago - in the picture transmitted back by the platoon leader, there were quite a few people coming and going from the mansions in the north of the city. It didn't look like they were fleeing with their families. look like.
In other words, the city was well prepared, and they could even estimate the approximate time when the beast tide would arrive.
But purely from an offensive and defensive perspective, the attacker is generally stronger than the defender.
I think that even if the city can be successfully defended in the end, the price paid should not be too small, and it is not impossible for the city to be destroyed and people to die.
Therefore, my personal preferred winning rate is seven to three, beast tide seven, and city three. "
Hearing this, another expert present suddenly coughed slightly and raised his hand.
This man's name is Dai Chaohong, he is in his early forties, wears a pair of gold-rimmed glasses, and has a gentle and capable temperament.
He is the second group of staff members who arrived at the camp with Lin Ziming. He is from the School of Humanities of Zhejiang University and is also an expert in social humanities.
Dai Chaohong had previously raised doubts about the height of the city wall and other issues, and had long made inferences about war.
After the inference was confirmed to be true, Dai Chaohong's prestige has greatly increased during this period, and he has almost become the vocal representative of the second group of experts.
His view on this war is opposite to Ma Ning:
"Professor Ma, I think the city has a better chance of winning.
First of all, in the video sent back by platoon leader Yu, we found many traces of later filling in the city wall.
Most of these traces are concentrated in the middle and upper parts of the wall, and the base can be said to be intact-this shows that the city wall has not been completely attacked.
Secondly, Platoon Leader Yu found signs around the Bajin Mansion that the city was well prepared for the incoming beast tide and had a relatively calm resettlement plan.
This shows that this city must not have faced or even defeated a beast tide for the first time. Coupled with the extraordinary power in the city, I think the two sides are at least 50-50 apart. "
Wang Qiang whispered quietly from the side: "The magic power is 73%, the dream is 50%, okay, it's all together. I don't know if the 10,000 yuan economy was overturned, or if it was taken away in a 3-0 wave."
Lin Li didn't hear the mumblings of the older leftover woman. After quietly listening to the opinions of the two experts, he turned to Lin Ziming and whispered, "Colonel Lin, what do you think? Do you think we should be ready to join the war?"
Lin Ziming pursed his lips a few times, hesitated to speak, and finally said hesitantly: "I do have some ideas, but I'd better wait until Captain Yao lands before talking."
"Waiting for Captain Yao to land? Hasn't the situation on his side been reported?" Lin Li thought for a few seconds, suddenly thought of something, and said suddenly: "I understand, you want to see the damage to the plane Can you make a judgment based on the extent?"
Lin Ziming nodded: "Yes, I plan to wait for Captain Yao to return and ask Lao Yan to dispatch a few mechanics from the air defense company directly under his regiment to check the damage to the airframe and landing gear.
No matter how mysterious the flame is, its core cannot be separated from the word energy - it's just a different way of expression.
Now our technical means are very advanced and we can fully measure the power of that flame. "
Lin Li hummed softly, obviously agreeing with Lin Ziming's idea.
After Yao Rong’s personal test not long ago, the camp has now confirmed one thing:
Explosive explosives can threaten the lives of ordinary alien beasts, and can break through the surface defense of the leader-level giant snake, causing it a certain degree of damage.
You know, the explosive used by Yao Rong and the others weighs five kilograms, which is 2.5 kilograms.
This kind of equivalent is undoubtedly a source of great danger to ordinary people.
But in the military industry
This kind of blasting explosive can only be considered mediocre in terms of yield and power - note that the last four words are not the irony of Principal Gu, but really mediocre.
CL-20, RDX, PETN and even Octogen, etc., there are many military materials that are more powerful than demolition explosives.
Not to mention those medium and large weapons such as missiles and howitzers, there are many that can penetrate the soul with one shot.
At the very least, the rabbits don’t have to worry about embarrassing things like in the Starship Troopers movies, where hot weapons cannot penetrate the skin of alien animals.
But for a stable creature like a rabbit, simply understanding the ‘defense’ of alien beasts is not enough.
The ‘attack’ of alien beasts also needs to be explored thoroughly.
After all, no one knows whether the extraordinary creatures in this world will be like a certain Gomura Gundou anime, all of which are characters with low defense and high attack.
Only by understanding the destructive power of the commander-level beast can the headquarters truly make the next decision.
Half an hour later, Yao Rong's crew successfully landed and returned.
Lin Li, who had been waiting here for a long time, quickly stepped forward, holding Yao Rong's hand tightly and moving it up and down: "Captain Yao, thank you for your hard work. Welcome back!"
Yao Rong, who had been through a life-and-death situation, looked slightly excited, and the corners of his eyes were a little moist: "Captain Lin, fortunately you have lived up to your fate!"
Lin Li let go of his hand, patted Yao Rong's shoulder hard, and then called for a support staff: "Xiao Lin, please take Captain Yao and the two of them to the tent to rest and recover."
After Yao Rong and Yu Guanghui left.
Lin Li turned his head, pointed at the damaged helicopter more than ten meters away, and said to the three mechanics from the air defense battalion beside him: "Comrades, I'm sorry to trouble you."
The three mechanics said yes, and two of them rolled up their sleeves skillfully, walked to the helicopter with two instruments, and inspected the damaged landing gear.
The remaining person stayed aside and entered the data measured by the two colleagues into a computer.
Twenty minutes later, the machinist responsible for inputting data stood up and reported: "Team Lin, there are results."
Lin Li immediately asked: "What is this comrade's name? How are the test results?"
"My surname is Zhao. Team Lin can just call me Xiao Zhao."
Xiao Zhao touched his head shyly, showed a simple smile, and then straightened his expression:
"My colleagues conducted salt spray tests and ridge laser measurements on the helicopter's landing gear, input the sample transmission information into a set of X programs developed by the military industry, and obtained a series of data through modeling."
As Xiao Zhao spoke, he handed over a newly printed report:
"First of all, the salt spray test detected the corrosiveness of the luminous flame. The corrosion rate is approximately 145.78mm/a, which means the corrosion depth of 145.7mm of metal per year, which is extremely severe corrosion."
Lin Li took the form and looked at it for a few times, with a look of confusion on his face: "145.7 millimeters per year? That means it's only about half a millimeter a day? But I think the crack in the landing gear is at least 30 centimeters deep, right?"
Xiao Zhao explained: "Team Lin, the damage to the landing gear was not entirely caused by strong acid. First, the kinetic energy of the flame damaged the landing gear, causing the breach you mentioned, and then the acidic substance adhered to it. On top of it, corrosion gradually began.”
Lin Li nodded: "I understand, Comrade Xiao Zhao, please continue."
Xiao Zhao handed over another report:
“This is the result of our simulated kinetic energy unit testing.
Since only the edge part of the flame grazed the fuselage, we first estimated the kinetic power of the flame that hit the landing gear based on the degree of damage to the landing gear.
Then, based on the side spacing recorded in the last frame of the camera, and with the assistance of the X program, we constructed a model using laser-measured ridge data to restore the theoretical values of various data on the flame body. "
Lin Li couldn't wait to ask: "What is the theoretical value?"
Xiao Zhao replied: "AC311A is a civilian aircraft, and the landing gear is not made of military alloy. According to our calculations, the flight speed of the flame body is about Mach 1.2, which is 1.2 times the speed of sound. It took a total of 1.227 seconds from launch to grazing the aircraft body. Second.
The upper limit of the energy of the flame body is 3265.3 kilojoules, and the lower limit is 1753.2 kilojoules. "
Lin Li pondered for a while and continued to ask: "Commander Yan and his 9999A tank, right? How much energy can it penetrate?"
Xiao Zhao smiled again and corrected Lin Li's misunderstanding:
"Team Lin, to rely on explosion to destroy a hard target, what is needed is not the total energy, but the mechanical energy caused by the explosion, which means the explosion speed must be very high.
Take my country's more famous anti-tank missile Hongjian 8 as an example. The armor-piercing thickness of the warhead is about 800 mm. A standard Hongjian 8 can penetrate the 99A armor from the flanks, but it cannot hit the front main armor with one shot. wear. "(Note 1)
According to our calculations, the mechanical energy generated by the flame when it explodes is approximately equal to a quarter of our 'Red Arrow 8'.
In other words, the flame cannot pose a threat to our main battle tanks, but it has a certain fatality rate to the infantry. "
Note: Let me tell you here why I used anti-tank missiles as an example instead of howitzers.
The charge capacity of howitzers is generally 6-8 kilograms, and the charge capacity of Red Arrow 8 is 1.5 kilograms, but the goals of the two are completely different.
Howitzers are generally aimed at cluster targets, and anti-missile targets are generally aimed at a single tank or armored vehicle. In addition, the size of the flame is similar to that of anti-missile targets, so I will directly use anti-missile targets as an example.
There is another reason why we don’t use the howitzer as an example. Howitzers hit tanks. Anyone who has been in military forums knows that this issue can lead to the day when the national football team enters the World Cup.
