With the support of the chief of armaments, Bai Yi has no worries at all. However, it is difficult to completely let go. After all, the relevant report drafted by the chief of armaments still needs to be reviewed by the central government. After many twists and turns, time is naturally too late.

.

Therefore, the chief of armaments could only detain a few T-345 tanks that needed maintenance in the name of logistical maintenance, and let Bai Yi try to modify them without damaging the tanks.

Although Bai Yi was helpless, he also knew that this was the best condition that the head of armaments could provide at present, so he devoted himself wholeheartedly to the modification project of the T-345 tank.

His first task is to develop a tank gun smoker. In theory, Bai Yi has no problem with this. The key difficulty is that he does not have the people and equipment at hand.

Fortunately, at this time, Song Jixue, secretary of the Baiyun Factory Party Committee, led Chen Yaoyang and a large number of technical backbones from the Baiyun Factory to North Korea to inspect the operation of the train's anti-aircraft artillery system on the spot, so that after returning, problems exposed in the use of the troops and actual combat could be investigated.

Solve and improve.

So Bai Yi went directly to Song Jixue and told him what the chief of armaments meant. Song Jixue naturally understood what this meant for the future of Chinese tanks and armored vehicles, and immediately left a group of technical backbones with him to Bai Yi.

At the same time, an urgent telegram was immediately sent to Baiyun Factory, requesting cooperation with Bai Yi.

With the backing of Baiyun Factory, Bai Yi is even more confident.

However, just when Bai Yi was thinking about how to coordinate the equipment in North Korea with the Baiyun Factory in China, the head of the armaments department gave him another shot in the arm!

It turns out that North Korea built a tank repair factory with Soviet aid at the beginning of its independence. After the outbreak of the Korean War, the factory was destroyed in a U.S. air strike.

However, after nearly a year of bloody war, northern North Korea was stabilized. North Korea, eager to restore its economy, once again applied to the Soviet Union, hoping that Big Brother could help them repair and rebuild the destroyed tank.

The Soviet Union was extremely generous in this regard. Not only did it agree to North Korea's request, but in order to save time, it directly relocated an entire tank repair shop located in the Far East of the Soviet Union to Chen'anli, north of Pyongyang.

Just a few days ago, this tank repair shop was officially completed. After the military chief learned of the situation, he immediately contacted the North Korean side. After several negotiations, the North Korean side finally agreed that the Volunteer Army Logistics Department can use the mechanical equipment of the repair shop for repair and maintenance.

own tank.

Bai Yi was ecstatic about this, because this solved the equipment he was in urgent need of. Now that he had the talent and equipment, the development of tank gun smokers was officially put on the agenda.

In fact, it is not difficult to talk about the basic principle of the tank gun's smoking device. It is nothing more than putting a sealed hollow hoop on the tank gun as a gas storage tank.

The covered part of the barrel will be turned into several oblique holes in the direction of the muzzle. When the cannonball passes through these oblique holes, the high-pressure gunpowder gas will be poured into the external gas storage tank and "stored".

When the cannonball flies out of the muzzle, the pressure in the chamber drops instantly. This means that the high-pressure gas in the gas tank will eject high-speed airflow toward the muzzle. According to the principle of fluid mechanics, negative pressure will appear behind the airflow at this time.

This creates a forward air pumping effect.

It has to be said that this device is both simple and exquisite, and the effect is first-class. Otherwise, this device would not be regarded as standard equipment and become a necessity for every tank starting from the second generation tanks.

It's just that the tank's smoking device is simple. It's not easy to make the entire beard and tail. Especially the several oblique process holes punched in the barrel will affect the airtightness of the artillery if they are enlarged.

If it is too small, it will be ineffective. Therefore, only by calculating the best theoretical value based on the caliber of the specific tank gun, the amount of charge, the initial velocity of the projectile, and the corresponding exhaust gas concentration can we determine the location of the diagonal process hole in the barrel.

range, size and quantity.

However, it is not enough to determine some numerical values. The difficulty of processing is definitely even more difficult than complicated theoretical calculations.

You must know that the steel used to make tank guns has very high indicators in terms of hardness and toughness. Therefore, if you want to drill a few holes in this hard and tough gun steel, it itself raises challenges for machining.

Very high requirements; what's more, if this diagonal process hole is not drilled properly, it will not only affect the strength of the gun barrel, but also cause poor sealing, resulting in the entire tank gun being scrapped.

Because of this, accurate and efficient drilling processing has become the key to the success or failure of the tank gun smoker!

If other people were faced with such a seemingly simple but actually complex technical problem, they would not be able to find a solution for a year and a half. Not to mention anything else, the theoretical calculation of light oblique process holes is enough for the average person to count three or five.

months.

However, this kind of technical difficulty that makes other people's scalps go numb is a small problem that can be solved easily for Bai Yi. After all, in his previous life, tank maintenance was a key subject of the military equipment college where he was located, and as the most important subject of tanks,

The important weapon tank gun is one of the key points in the tank maintenance project.

Therefore, the various subjects involved have been with Bai Yi from the moment he entered the college. Not only that, in order to increase students' understanding of all aspects of tanks, the school often prevents students from going to the tank production workshop.

Go for an internship.

Because of this, Bai Yi was sent to the tank factory, and was fortunate enough to become a member of the tank gun production workshop. He worked in the tank gun production for more than two months, and not only felt the tank gun inside and out.

, and also learned a lot of the factory’s unique skills in pressing boxes during production practice.

Among them are two top-level unique skills: the rapid calculation of mathematical model formulas for tank smoker diagonal process holes and the diagonal fine machining of ordinary drilling machines.

Because of this, something that seems very difficult to others, in Bai Yi's hands, is just a matter of formulating a mathematical model and then calmly positioning it and drilling a hole.

If it weren't for the technical backbones of Baiyun Factory who followed him, Bai Yi deliberately slowed down the progress so that those technical backbones could have time to practice and digest, Bai Yi would have completed the smoking of the T-345 tank at an even more alarming speed.

Device modification!

However, even though Bai Yi has delayed the progress to the point where he is impatient, in the eyes of others, Bai Yi's efficiency is still surprising.

Not to mention others, Major Zaharov standing in front of him at this time was one of them. When he confirmed from Zhang Huangxin that Bai Yi was the inventor of the tank gun smoker, Major Zakharov immediately looked confused.

He was solemn, and then gave a thumbs up to Bai Yi with admiration: "Comrade, your tank gun smoker really opened my eyes to you for being able to create such an exquisite device in such a short period of time.
Chapter completed!
