Chapter 146 Angry Director Gao (3k)

Everyone present was a little confused. It didn't need to be that thick to meet the design requirements.

The 4DL people were a little impatient: "To lose weight."

Gao Zhendong continued, "I know the steel I made. The density of 592 should be not much different from the original steel. Since other conditions have not changed, combined with the density of 592, it means that the original thickness remains unchanged and can also meet the engine power-to-weight ratio requirements. Then who can tell me why the thickness of the armor should be reduced?"

These words stunned everyone at the scene. Yes, since the power-to-weight ratio is not a problem, why should the thickness of the armor be reduced? Wouldn't better armor steel provide better defense with the same thickness?
Gao Zhendong did not stop talking: "I don't know why you insist on the bulletproof design index and try to reduce weight. I have done experiments with colleagues from related factories and institutes. xxmm thick 592 can protect against 12.7mm armor-piercing explosive incendiary bombs at a range of 75 meters at xx normal angles."

When they heard about such performance, the eyes of the Defense Work Committee and the user representatives lit up. This performance was something they had never dared to imagine before.

From 7.62mm to 12.7mm, the caliber is almost doubled, but the power increase brought by it is far more than doubled.

Yes, maintaining the original thickness, wouldn't it be good if the front of the vehicle body could defend against 12.7mm penetrating and explosive close-range shooting? Why do we have to insist on defending against 7.62mm bullets?

The user representative stood up and saluted Gao Zhendong: "Director Gao, thank you!"

Gao Zhendong turned around and nodded to him, without stopping his words: "Maintaining the original thickness can greatly increase the protection performance of armored vehicles and improve the combat effectiveness and survival rate of soldiers, and there is no need to consider the center of gravity change issue you mentioned. In my opinion, there is no need to discuss this issue."

Gao Zhendong was actually a little angry about this situation. He had the final words on the issue: "We strive to make better armor steel so that soldiers can be better protected in combat under the same conditions. We do not recommend using it to rob Peter to repair Paul."

This was said rather sharply, and there was a silence at the scene.

Soon after, the user representative formally proposed to the designer: "Comrade, we formally request that the armor weight cannot be reduced."

The leader of the Defense Work Committee made the final decision: "We will follow Comrade Zhendong's opinion on this matter."

Gao Zhendong is not afraid of offending people. If you want to always maintain harmony in technical work, you will cause trouble for yourself and your work. People still have to insist on some correct things.

In his previous life, he had often seen his mentor and colleagues banging the table and hitting the bench over technical issues, and after they finished discussing the technical issues, nothing happened.

The discussion continued, and seeing that the matter was almost resolved, Gao Zhendong also recalled some related situations he had seen in his previous life, but here, just like in his previous life, no one remembered them.

This is normal. This is the first time for everyone to do this, and there are some unexpected things that cannot be solved.

Fortunately, you haven't thought of it for the time being, but Gao Zhendong knows it, especially the targeted improvements of 4DL in the future.

He took advantage of a break when everyone was speaking and raised his hand: "I have something to say."

The leaders of the Defense Working Committee and the representatives of the users looked delighted. Judging from Director Gao's style, he never fired blanks. He must have discovered something and was taking targeted action.

The leader of the Defense Work Committee looked at Gao Zhendong and said, "Director Zhendong, please speak."

The others also looked at him, waiting for him to speak. They had already experienced this man's abilities and temper.

Gao Zhendong looked around, nodded to everyone, and then said, "I have some suggestions and opinions on some details of 4DL."

Suggestions and opinions may sound similar in review meetings, acceptance meetings, etc., but their meanings are completely different.

It is recommended to be more tactful, or to say from the speaker's perspective, you can listen to it or not, but it is best to listen to it.

"Opinion" is much more formal. The word "opinion" is usually used when a problem has been identified. The situation or consequences of the problem have a significant impact and definitely need to be improved or addressed. From the speaker's perspective, it has a certain degree of compulsion.

If it ultimately comes down to a formal written document, in principle you can respond or not, but as for the opinion, you must respond.

Anyone who has written standards knows that there are two words: "should" and "should." Here, suggestions are "should" and opinions are "should."

Gao Zhendong continued: "I am not an expert 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 4DL design drawing hanging on the side, pointing at the body of the vehicle: "First of all, we just discussed and decided that there are only three shooting holes. This number is a bit too few. At least one shooting hole should be added on each side of the rear of the vehicle, and one on the tailgate."

The designer smiled and said, "There is a ventilation window on the top of the rear of the vehicle. Just open it and stick your head out to shoot. Besides, the observation conditions at the shooting hole are poor, and it is not as clear as the ventilation window. The tailgate is even more unnecessary. Can it be used to shoot while escaping?" Gao Zhendong shook his head. "I think there is a big difference between being able to fight in the armored vehicle with protection and sticking half of your body out in the hail of bullets. The observation conditions at the shooting hole are poor, so open an observation window above the shooting hole and use bulletproof glass of appropriate thickness as protection. It is better than soldiers being outside with their upper bodies naked."

The user representatives nodded repeatedly after hearing this. Although Director Gao had never been to the battlefield, his considerations were still very thorough.

Little did people know that Director Gao had been on the battlefield.

"There were 13 people in a car, but only three guns were usable while moving, and the firepower could not cover all directions, which was a bit of a waste."

"As for what you said about the tailgate being used for escaping? Comrade, there is something wrong with your thinking. This is used when our soldiers charge too bravely and directly rush into the rear of the enemy's front line."

After hearing what Gao Zhendong said, the representative of the user party couldn't help but burst out laughing. In the words of later generations, this is called defeating magic with magic.

Because that sentence is really hard to respond to, it's a big pitfall.

As a result, Director Gao simply avoided this pit and dug another big pit.

The user representative smiled and saw everyone looking at him. He quickly spoke: "Well, Director Gao is right. Our soldiers are too brave in charging. This is common. It is necessary. It is necessary."

Gao Zhendong nodded to him and continued to speak of his thoughts: "At the same time, it is recommended to install an active fan ventilation system in the vehicle, so as to maximize the combat effectiveness of the soldiers after the march in the vehicle."

"Director Gao, this will destroy the airtightness of the car body, and it will be difficult to achieve the three-protection system."

In the end, the collective three-defense system was not actually achieved, but I can’t say that.

"We've already opened so many ventilation windows, so we don't care about this. The power of the fan ventilation system won't have much impact on the engine power. Besides, if we want to build a collective triple-defense system, it must be an overpressure collective triple-defense system. Doesn't the overpressure collective triple-defense system require an air inlet? We can just integrate the air ducts of the two systems."

Other experts also agreed: "Director Gao is right. Even if the three-defense system cannot be achieved, this ventilation system can greatly improve the environment inside the car."

"Yeah, yeah, we can't open the roof ventilation window even when it's raining."

"It is necessary to solve the practical problems of the soldiers without taking too much trouble."

This is a discussion, and there is no need to wait for a resolution. Gao Zhendong continued to express his opinion: "The next one is where I disagree the most. The original 12.7mm anti-aircraft machine gun on the roof was reduced to a 7.62mm machine gun. In my opinion, this is unacceptable."

"Director Gao, this is what we have finally determined after detailed discussion. The firepower of the 7.62mm machine gun is enough for the armored personnel carrier to defend itself."

"I don't know how you guys are justifying this. In fact, the consequence of this is that the soldiers may fight the enemy after getting off the vehicle, but the armored personnel carrier has only armor and the best attack or fire support conditions in the infantry squad, but it only has a small water pipe, which is completely unable to support the charging soldiers and suppress the enemy's firepower."

"Then let the armored vehicles get closer, so that we can get it."

Gao Zhendong's face changed. "Comrade, I think you made your argument while sitting in your office, right? You can't imagine that under the complex terrain conditions on the battlefield, an armored vehicle relying on mechanical walking devices cannot advance as far as a soldier on two legs. It can't keep up! The range of the 7.62 machine gun cannot make up for this distance difference."

After that, Gao Zhendong gave an example: "Let's not talk about anything else. When the soldiers go to the high ground with complex terrain, can you let the armored vehicles climb a mountain for me to see?"

The user's representative was surprised. Director Gao was so knowledgeable and a real all-rounder. He had taken the actual situation in the battle into consideration very thoroughly.

This was actually the most complained thing about the new 4DL trial vehicle by the troops later on. The 7.62 small water pipe is useless, and caliber is justice.

What the lovely soldiers complained about most was not the ventilation, high heat, or high noise, but the lack of firepower.

Gao Zhendong did not stop: "Not only do we have to change the 7.62 machine gun to a 12.7 high machine gun, but also, that bare machine gun firing position is simply a no-brainer. If a real battle breaks out, how many soldiers will be sacrificed on that bare machine gun firing port, I dare not even think about it!"

"My opinion is that we should also use armored steel plates to surround the high-altitude machine gun firing position. It won't add much weight, but it can greatly increase the combat effectiveness of the soldiers in battle. Your original design is simply playing with the lives of the soldiers."

This speech made the person in charge of the firepower of 4DL look angry and said, "Director Gao, didn't you come up with all these in the office? How can you be sure that the firepower is insufficient? At least we have discussed it with everyone and it is the collective wisdom."

After hearing this, Gao Zhendong laughed out of anger.
