Chapter 146 Angry Director Gao (3k)
Everyone present was a little confused, so it doesn’t need to be so thick to meet the design specifications.
The people at 4DL were a little impatient: "In order to reduce weight."
Gao Zhendong continued: "I know the steel I make, and the density of 592 should not be far from the original steel. Since other conditions have not changed, combined with the density of 592, it means that the engine power-to-weight ratio requirements remain unchanged, so who can tell me why the armor thickness needs to be thinned? "
These words immediately stunned everyone present. Yes, since the power-to-weight ratio is no problem, why should the thickness of the armor be reduced? With better armor steel, wouldn’t the same thickness provide better defense?
Gao Zhendong did not stop talking: "I don't know why you insist on that bulletproof design indicator, but go to lose weight. I have done experiments with comrades from relevant factories. xx mm thick 592, in xx At the normal angle, it can prevent 12.7mm armor-piercing explosive and incendiary bombs from being fired at a range of 75 meters.”
When hearing about such performance, the eyes of representatives from the National Defense Working Committee and the user brightened. Well, this performance was something they didn't dare to think about.
7.62mm to 12.7mm, almost twice the caliber, brings far more than twice the power increase.
Yes, if the original thickness is maintained, the front of the car body can protect against 12.7mm deflagration at close range. Why should it insist on protecting against 7.62mm bullets?
The user representative stood up and saluted Gao Zhendong: "Director Gao, thank you!"
Gao Zhendong turned to him and nodded in greeting, without stopping to say: "Maintaining the original thickness can greatly increase the protective performance of armored vehicles and improve the combat effectiveness and survival rate of soldiers without having to consider what you said. Regarding the change of focus, in my personal opinion, there is no need to discuss this issue.”
Gao Zhendong was actually a little angry about this situation, and he said the last sentence about this issue. Words: "We strive to make better armor steel so that soldiers can be better protected in battle under the same conditions. We do not recommend using it to make up for the west."
The words were said a bit sharply, and the scene was completely silent.
Not long after, the user's representative formally proposed to the designer: "Comrade, we formally request that the weight of the armor cannot be reduced."
The leader of the National Defense Work Committee made the final decision: "This matter will be handled in accordance with Zhendong Comrade’s opinions.”
Gao Zhendong is not afraid of offending others. If you want to maintain harmony forever in technical work, you are causing trouble for yourself and your work. People still need to have some correct persistence.
In his previous life, he often watched his mentors and colleagues slam the table and bench over technical issues. When the technical issues were discussed, nothing happened.
The discussion continued, and seeing that the matter was almost resolved, Gao Zhendong also remembered some related situations he had seen in his previous life, but here it was still the same as in his previous life, and no one remembered it.
This is normal. It is the first time for everyone to do this. There are some things that are unexpected and there is no way.
Fortunately, you haven’t thought of it yet, but Gao Zhendong knows about it, especially the targeted improvements of 4DL in the future.
He took advantage of a gap when everyone was speaking and raised his hand: "I have something I want to say."
The leaders of the Prevention Working Committee and the user representatives looked happy, judging from the style of Director Gao Look, they never fire cannons. They must have discovered something and were targeted.
The leader of the National Defense Working Committee looked at Gao Zhendong: "Director Zhendong, please speak."
Others also looked at him, waiting for him to speak. This man's ability and temperament, I’ve just learned the lesson.
Gao Zhendong looked around, nodded to everyone, and then said: "I have some suggestions and opinions about some details of 4DL."
Suggestions and opinions may sound similar in review meetings, acceptance meetings, etc., but they have completely different meanings.
It is recommended to be more tactful, or from the perspective of the speaker, you can listen to this matter or not, but it is best to listen.
Opinion is more formal. The word "opinion" usually means that the problem has been grasped to death. The situation or consequences of the problem have a greater impact and must be improved or dealt with. This word is used from the speaker. From a certain perspective, it has a certain degree of compulsion.
In the end, if it comes down to a formal document, the suggestion may or may not be responded to in principle, but the opinion is that it must be responded to.
Everyone who writes standards knows that there are two words: "should" and "should". Here, the suggestion is "should" and the opinion is "should".
Gao Zhendong continued to speak: "I am not a professional in the major components of armored vehicles, so I can't say much, but I have some ideas about the details."
He stood up and walked to the hanging Next to the 4DL design drawing on the side, he pointed to the car body part: "First of all, we just discussed that there are only three shooting holes. This number is a bit small. At least one shooting hole should be added to the left and right of the rear of the car body, and there should also be one shooting hole on the tailgate. Add one more.”
The designer smiled and said: “Isn’t there a ventilation window on the top of the rear body? Just open the ventilation window and stick your head out to shoot. Besides, the observation conditions of the shooting hole are poor, so it’s better to You can see clearly through the ventilation window. There is no need for a tailgate. Is it used for shooting when escaping?" Gao Zhendong shook his head: "Can I shoot in the armored vehicle with half of my body in the hail of bullets? I think this is it. The difference is still huge. If the observation conditions of the shooting hole are poor, it is better to open an observation window above the shooting hole and use bulletproof glass of appropriate thickness as protection than to leave the soldiers with their upper bodies naked.”
These words made the user representatives nod their heads repeatedly. Although Director Gao had never been on the battlefield, he was still very thoughtful.
As everyone knows, Director Gao has been on the battlefield.
“There are 13 people in a car, but only 3 guns can be used while traveling, and the firepower cannot cover all directions, which is a bit of a waste.”
“As for the tailgate you said Is it used when escaping? Comrade, you have a problem with your thinking. This is used when our soldiers rush too bravely and rush directly behind the enemy's lines."
Hearing Gao Zhendong's words. The user didn't hold back and laughed out loud. In the words of later generations, this was called using magic to defeat magic.
Because that sentence is really not easy to answer and is a big trap.
As a result, Director Gao directly bypassed this hole and dug another big hole.
The user representative smiled and saw everyone looking at him. He quickly spoke: "Well, what Director Gao said makes sense. Our soldiers charge too bravely. This is common, necessary, necessary. "
Gao Zhendong nodded to him and continued to talk about his thoughts: "At the same time, it is recommended to install an active fan ventilation system in the car, so as to maximize the maintenance of the soldiers after marching in the car. "Director Gao, this will destroy the sealing of the car body, and the collective three defenses are not easy to do."
In fact, the collective three defenses are not good at this. I haven’t made it yet, but I can’t say that.
"We have opened so many ventilation windows that we don't care about it anymore. The power of the fan ventilation system will probably not have any impact on the engine power. Besides, if we want to build a collective three-proof system, it probably means overpressure. Don’t the collective three-defense and over-pressure three-defense systems need air inlets? Just integrate the air ducts of the two systems.”
Other experts also agreed: “Director Gao makes sense. , even if collective three-proofing is not possible, this ventilation system can greatly improve the interior environment of the car.”
“Yes, you can’t open the roof ventilation window even when it rains.”
“It is still necessary to solve the practical problems of the soldiers without spending too much money.”
This is a discussion, and there is no need to wait for a decision for the time being. Gao Zhendong continued to express his opinion: “Continue This is where I have the biggest objection. Reducing the original 12.7mm anti-aircraft machine gun on the roof to a 7.62mm machine gun is unacceptable in my opinion.”
"Director Gao, this is what we have finally determined after detailed demonstration. The firepower of the 7.62mm machine gun is enough for the armored personnel carrier to defend itself."
"I don't know how you justified it. In fact, this brings The consequence may be that the soldiers got off the vehicle and fought hard with the enemy. However, the armored transport vehicle had no armor and had the best conditions for attack or fire support among the infantry squads. However, it only had a small water pipe and could not support the charge at all. Soldiers, suppress the enemy's firepower."
"Then let the armored vehicles get closer, so we can get it."
Gao Zhendong's face changed: "Comrade, I think. Did you make your argument while sitting in the office? You can't imagine that under the complex terrain conditions on the battlefield, an armored vehicle relying on a mechanical walking device cannot keep up with a two-legged warrior. No! The range of the 7.62 machine gun cannot make up for this distance gap."
After that, Gao Zhendong gave an example: "If nothing else, when the soldiers go to the high ground with complex terrain, you let them go. Can the armored vehicle climb a mountain and show it to me? ”
The user's representative was surprised. Director Gao was so knowledgeable. He was an all-rounder and had considered the actual situation in the battle very carefully.
This was originally the place where the troops complained the most about the new 4DL trial car. The 7.62 small water pipe is useless, and the caliber is justice.
What the lovely soldiers complain about most is not the ventilation, high heat, and high noise, but the lack of firepower.
Gao Zhendong did not stop: "Not only must the 7.62 machine gun be changed to a 12.7 high-speed machine gun, but the shooting position of the bare machine gun is simply out of control. If a war really breaks out, how many soldiers will die on that bare machine gun?" I don’t even dare to think about it!”
“My opinion is that armored steel plates should be used to surround the shooting positions of high-altitude aircraft. It won’t add much weight, but it can greatly increase the strength of the soldiers in battle! Combat power. Your original design is simply making fun of the lives of soldiers.”
This output made the person in charge of the 4DL firepower department darken his face and became a little anxious: "Director Gao, didn't you think of what you said in the office? How can you be sure that the firepower is insufficient? At least for us It was determined after everyone’s discussion, and it is the collective wisdom.”
When he said this, Gao Zhendong laughed angrily.
