"Xiao Lu, you don't have to do this!" On the way to Wanshan Factory to the local garrison guesthouse in Sanlin, an army-green 212 jeep was galloping forward. The handsome and lush osmanthus trees on both sides of the road were like beautiful and passionate girls, swaying lightly in the slight summer breeze, echoing the beautiful peaks formed by the Astorian landform not far away, forming a fascinating and beautiful scenery.

However, this intoxicating beauty did not make anyone on the jeep look at it and linger, especially Wang Chuanchen, director of the Weapon Planning Department of the General Staff Equipment Department sitting in the back of the jeep. He is the core figure in the General Staff actively promoting and supporting Lu Jiadong's new artillery project.

Because of this, when the new large-caliber long-range artillery was officially launched, Wang Chuanchen was personally appointed by Tan Bin, Director of the General Staff Equipment Department, to serve as the leader of the new artillery project leadership group, mainly responsible for the dispatch of various resources and the coordination and liaison between military and local parties.

As the deputy team leader, Lu Jiadong also serves as the chief designer and is responsible for the comprehensive development of new artillery. It should be said that the two are old partners. As early as the 130mm bottom grenade project, the two teams worked together to carry out the development work. Speaking of the two meeting, it can be said that they are very familiar with each other and have a very tacit understanding when they cooperate.

However, Wang Chuanchen has been very puzzled by Lu Jiadong's approach recently. You should know that some of the weapons and equipment Lu Jiadong developed before must use some mature processes and technologies to reduce the development risks and costs. However, from the first day after the launch of the new artillery, Lu Jiadong seemed to have become a different person.

Almost none of the mature artillery manufacturing techniques and processes were useful, and all of them were used with new technologies and processes. Although Wang Chuanchen generally did not interfere in technology, as a senior military cadre who had been working in the field of military equipment for many years, Wang Chuanchen knew very well that if there were too many new technologies and processes used in a certain equipment,

Not only will this equipment encounter many difficulties to overcome during the manufacturing stage, even after the troops are installed, there will be many problems of one kind or another due to unstable performance. Especially not long ago, when I saw Lu Jiadong sleeping in the workshop, Wang Chuanchen felt that it would be impossible not to say it.

If this continues, let alone the performance of the artillery is difficult to guarantee, even the technicians involved in the artillery development will have some problems. Especially Lu Jiadong, he is still young, and there are still a long way to go in the future, and there are many places to need him. If the root cause of the disease is lost at this time,

Even if you want to contribute to the country in the future, you will be willing but not able to do it. In addition, it also involves research and development funds, development cycles, expert acceptance and other links. Because of these reasons, on the way to the Sanlin Garage Guesthouse, Wang Chuanchen couldn't help but persuade Lu Jiadong:

"Not to mention how much research and development funds we have spent on introducing these mechanical equipment. Just talking about the technical field, we almost use new technologies and new processes this time. Will the stability performance of our new gun reach a balanced indicator? So I think we should use some previous mature processes and technologies, which not only increases the stability of the new gun but also shortens the development time. The most important thing is......"

As he said that, Wang Chuanchen couldn't help but pause, and then looked at Lu Jiadong beside him with concern and continued:

"In this way, Xiao Lu, you don't have to be so tired!"

Lu Jiadong understood Wang Chuanchen's words very clearly. To be fair, he was right. If there were too many new technologies and new processes used in a weapon and equipment, it would easily lead to unstable performance of modified weapons and equipment. For example, the "Arjun" tank equipped by later India continued to add the latest technologies and processes to it during its development process, which made this type of tank unable to complete its development. It took 30 years intermittently and could finally be equipped with troops.

But what was unexpected was that this so-called "domestic" tank that the Indian military industry is proud of has frequent failures after being installed in the army, and cannot even complete the most basic combat tasks. In the end, it can only become the so-called "military parade tank" and become a joke in the world military industry. The reason is that it is to pursue high performance but unrealistic piles up various advanced technologies, resulting in extremely unstable performance of the weapon system.

As a military expert who traveled through time in later generations, Lu Jiadong naturally knew this truth very well. In fact, according to Lu Jiadong's perspective, the key technologies used in the new artillery project currently developed, such as self-tightening of the body tube and remelting of the electric slag. Not to mention in the 21st century decades later, even if it is viewed in the world today, these two technologies are not the latest.

As early as the late 1960s and early 1970s, Britain and Germany took the lead in using electroslag remelting and self-tightening technology to manufacture tank guns. After achieving good results, they gradually promoted and applied them on other high-bucket pressure guns. It can be said that the key technologies for the manufacturing of these two artillery in the West have been very mature, and what Lu Jiadong has to do at present is to transform these mature Western key technologies into the Chinese's own technology.

For this reason, Lu Jiadong had already prepared for the future. Before Wanshan Factory was relocated, Lu Jiadong offered relevant courses in the youth training class, introducing in detail the advanced technology in artillery manufacturing. Not only that, Lu Jiadong also gave special explanations and teachings to the young employees of these Wanshan Factory's knowledge and technology in foreign languages, computers and CNC machine tool operation.

After nearly a year of development, it can be said that Wanshan Factory has a certain foundation for new manufacturing talents. Now that the new artillery project has officially started, for Wanshan Factory, as long as it provides a little guidance and training, it should not be a problem to master these new technologies and new processes. It is precisely because of this confidence that Lu Jiadong dared to drastically introduce these new equipment and manufacturing processes that others dare not imagine...

"So, our Wanshan Factory still has this foundation. For example, Liu Liang, whom you know, Director Wang, was developing a portable rocket launcher, went to the Materials Research Institute to learn computers and CNC machine tools, as well as Chen Zihao and Zhang Aiguo. Their theoretical knowledge and operation skills are very good, and what they lack is practical experience. However, now Wanshan Factory has transferred many professional talents and skilled workers in the field of artillery production, so we have overcome this shortcoming!"

"I know that your Wanshan Factory has an effective training and education system, but I didn't expect that you would look so far and have made relevant technical reserves so early!" After hearing Lu Jiadong's words, Wang Chuanchen showed a look of excitement on his face, but when he finished speaking, Lu Weijun, the representative of the army in charge of driving, he smiled and said:

"The chief is not only the training staff, but also the development of our new artillery, Chief Secretary Lu's eyes are far away!"

"Oh?" After hearing Lu Weijun's words, Wang Chuanchen couldn't help but be surprised. Lu Weijun did not look back because he wanted to drive, but he could also feel Wang Chuanchen's gaze behind him, so he continued to say while driving:

"If you don't say anything else, just say that this set of self-tightening equipment can not only be used on the new type of artillery we are developing now. If I'm right, the main gun on the tank can also use this technology to enhance the structure of the gun body!" As he said, Lu Weijun moved his eyes to look at the rearview mirror in front, and looked at Lu Jiadong sitting in the back row through the mirror and asked with a smile;

"Chief Commander Lu, am I right?"

After hearing Lu Weijun's words, Wang Chuanchen's face flashed with a slight excitement. Although he did not say that he was so good at artillery technology to the Lu Weijun, he was also very clear about the importance of tank guns. Because of this, Wang Chuanchen stared at Lu Jiadong and asked:

"Xiao Lu! Can this set of equipment really be used in tank main guns?"

"Representative Lu is right!" Lu Jiadong nodded, then looked at Lu Weijun who was driving in front of him with praise: "In fact, the long-range artillery we are developing now has a basic principle with the tank main gun, that is, when the ammunition is fired, the chamber pressure is very high, and the greater the chamber pressure, the larger the initial velocity of the shell. This indicator is reflected in the long range of the suppressed artillery, and when it is put on the tank main gun, it is manifested as armor-piercing kinetic energy and power!"

"So this requires strengthening the body tube structure of the artillery to withstand huge gun barrel pressure?" Although Wang Chuanchen is not as proficient as Lu Jiadong and Lu Weijun in technology, his years of experience in military industry have also allowed Wang Chuanchen to train to a certain level. After hearing Wang Chuanchen's words, Lu Jiadong couldn't help but nodded in agreement:

"Director Wang is right, this requires increasing the structural strength of the barrel. In addition to using new high-strength gun steel and using electroslag remelting technology to remove impurities, the most effective method is the tightening technology of the body tube, and the self-tightening process of the body tube is the most effective.

The basic principle is that the inner mold of the mold is hollow, filled with cooling liquid, and pipes are connected on both sides. When the high-temperature heat-treated gun tube is loaded into the mold, the high-temperature-treated gun tube begins to cool slowly. At this time, the coolant in the inner mold comes in handy. The gun tube close to the inner mold is first cooled under the action of the coolant.
