my scientific age

Chapter 364 Pursue perfection if you have money, but just have enough if you don't have money!
Ten minutes later, as the thinking computer completed the calculation and verification of the last set of data at a rate of 10 million times per second, the initial design plan of the [-]-ton single-column electroslag remelting furnace appeared in the mind in a three-dimensional form. The internal structure of the body is clear, and the main circuit and supporting electrical equipment are readily available. After mathematical verification, the smelting work can be successfully completed, and cutting-edge gun steel materials that meet the mechanical performance requirements can be produced.

The gun steel materials of this era basically use high-quality alloy steel with low sulfur and phosphorus, which is not secondary refined alloy steel. Although it can meet the mechanical performance requirements of large-caliber artillery, the life of the barrel is generally not high.

If calculated by second, the life of the barrel may be less than one second, and calculated by rounds, it will be 200-300 rounds.

If electroslag steel, which is secondary refined by electroslag remelting, is used as the gun steel material, the life of the gun barrel will achieve a qualitative leap, reaching more than 600 rounds, supplemented by the self-tightening technology of the barrel and the chrome plating process of the gun bore, the life span can be extended. Up to three seconds!

Less than one second to three seconds, this is the role of electroslag remelting.

After completing all the calculation and verification work, Yu Hua only felt a slight dizziness in his head. This is a side effect of high-intensity calculation. He emptied his mind, gently rubbed his temple with his right hand, let the golden mathematical symbols relieve the side effects, and entered a state of rest.

After a short rest, the feeling of dizziness receded like a tide.

"Phew, it's basically done. The design work is over, and the next step is to enter the manufacturing process of the test furnace. The [-]-ton electroslag furnace is enough for base use. One furnace of electroslag steel can meet the needs of two gun barrels." After a short break , Yu Hua carefully checked the initial design of the [-]-ton electroslag furnace, confirmed that it was correct, and thought silently in his heart.

It became.

Yes, it's basically done.

It's just learning the basics.

"Team leader, this is the design plan of the 105mm artillery shell system. It is designed to imitate the Soviet-made artillery shell design according to your requirements. You can see what needs to be modified." Zhu Rui walked to Yu Hua quickly, raised his hand in salute, and then put it down A design airtight barrel with Top Secret printed on the surface.

The second type of ammunition, deflagration-1, is a complete ammunition, with a caliber of 105mm×380mm, a total weight of 15.5kg, a muzzle velocity of 580m, a conventional projectile structure, a TNT charge of 2kg, and thermite as the main combustion agent. The theoretical absolute killing radius is 7.5 meters, and the effective killing range is 25 meters.

After more than ten minutes, Yu Hua finished the second replay calculation in his mind, completed the review of the two types of projectile design schemes, and then nodded to Zhu Rui, giving approval and affirmation: "Comrade Zhu, the design scheme is very good, there is no problem, If it meets the requirements of the indicators, it can enter the stage of sample bomb trial production.”

Whether the 105mm shell system can pass the test is entirely up to Yu Hua to decide.

The approaching Japanese invaders would not leave them much time.

After I leave the base area, the shortage of talents will become more serious.

"It's done." After the drawing work was completed, Yu Hua carefully re-examined the drawings to confirm that there were no errors in each labeling parameter.

About an hour later, the complete design of the 1.5-ton electroslag furnace was released, with a total of [-] drawings.

"Hello, Comrade Zhu." Seeing Zhu Rui, Yu Hua nodded and greeted Zhu Rui with a smile, without putting on airs of an adjutant.

Zhonghua is about to smelt the world's first furnace of electroslag steel, and has the ability to independently produce cutting-edge gun steel materials, even if this "production capacity" is very likely to be one furnace per month.

"Report!" At this moment, the voice of guard Lu Junyu came from outside the door of the cave.

"If you have no other comments, I will sign and seal it here." Yu Hua said with a smile. Although the 105mm shell system solution has many shortcomings, it can already meet the combat needs of the Eighth Route Army.

Taking the Soviet artillery shell as the imitation target, developing a domestic 105mm shell system is a task arranged by Yu Hua for Zhu Rui. After the project was established and grouped, Zhu Rui was mainly responsible for this matter. During the period, Yu Hua gave occasional pointers and provided technical support and data calculation support .

"Dong dong!" At this moment, the cave door knocked gently.

The drawing process is familiar with the road, efficient and fast.

Without delay, Yu Hua opened the design sealed barrel, took out the design drawings placed in it, and spread them out. Two 105mm ammunition design drafts with similarities and minor differences came into view.

Now, the dawn is approaching.

Of course, he is still full of confidence in his design plan. After all, this is not an independent development, but an imitation based on the prototype of the Soviet Army's standard artillery shells.

Standing by the side, Zhu Rui held his breath, like a student waiting for the teacher to rewrite his homework, with a solemn expression on his face. Although Zhu Rui had received complete training in modern artillery and achieved excellent results in double materials, he was still the first in the field of weapons and equipment research. , he is just a freshman who just started.

The first ammunition model is high-explosive-1, complete ammunition, specification 105mm×380mm, total weight 15kg, muzzle velocity 580m, conventional high-explosive projectile structure, projectile material high-phosphorus steel, TNT charge 2.8kg, The theoretical absolute killing radius is 8 meters, and the effective killing radius is 20 meters.

This is another historic breakthrough from zero to one, and the significance and importance of this breakthrough is far more real than later generations realizing the smelting of ballpoint pen nib steel.

No matter how poor the performance is, it is still a 105mm caliber shell, and there is no problem in reimbursement of an infantry squad of a skirmish line with one shot.

It is not new in the military industry bureau to be the head of the first factory with a primary school education.

Time passed by every minute and every second, and there was no sound in the cave, except for the subtle sound of the pen scratching the manuscript paper for calculation.

One word, fast.

Hearing these words, Yu Hua shook his head lightly, expressing that he could do nothing about the shortage of talents, and could only hope that the students whom Professor Zhuang wrote to invite would arrive at the base as soon as possible.

Hearing this, Yu Hua didn't expect Zhu Rui to come up with the draft so quickly, and it took only half a month to calculate the time, but seeing Zhu Rui's haggard face, he felt a little understanding in his heart.

Once it is wrong, the consequences will be disastrous.

One can come one by one, share the research pressure and workload, and improve efficiency.

"I understand, but the available manpower is too small to be busy at all. Next, I will be responsible for the development of the 40mm shell system and the 12.7mm bullet system. I can't wait to split myself in half." Zhu Rui heard With these words, he nodded helplessly.

After rechecking the blueprint, Yu Hua felt relieved, picked up the cold teacup to his mouth, and took a sip.

"So fast?"

According to the standard process of later generations, it is inevitable to hold three or five meetings to confirm the design plan, but now is the age of war, and there are not so many rules and regulations.

Fortunately, it was done, passed the customs smoothly.

"Please come in." Yu Hua put down his teacup and responded.

The figure who pushed the door was Zhu Rui, walking in a hurry, exuding the efficiency and capability of a soldier. However, his whole body had a pair of panda eyes, bloodshot eyes, and a haggard look on his face.

If nothing else happened, Zhu Rui should not have had a good night's sleep for a long time.

It is a bit difficult for him to innovate, let him copy his homework...

The shortage of talents is a true portrayal of the current heavy weapons project team and various departments of the Military Industry Bureau. Among them, the heavy weapons project team is particularly serious. Engaging in the development of advanced weapons and equipment does not require a solid professional foundation in mechanical engineering and a wealth of knowledge reserves. Conditions are everywhere in later generations, but nowadays, they are really rarer than giant pandas.

From the perspective of project research, with the release of the design scheme of the [-]-ton electroslag furnace, the electroslag remelting technology project has made a major breakthrough, and the research progress has come to an end. The remaining work is nothing more than manufacturing the test furnace.

After thinking in Yu Hua's mind, he picked up the teacup next to him with his right hand and took a sip. Then he found a blank design drawing, picked up a pen and tools with both hands, and began to convert the design plan of the 1.5-ton electroslag furnace in his mind into a design drawing.

Rigorous and demanding, this is the basic requirement for engaging in military research, and no mistakes can be tolerated.

The atmosphere is slightly depressing.

Pursue perfection if you have money, but just enough if you have no money.

Design blueprints are critical, and mistakes can cause irreparable damage.

The design of the two types of ammunition designed to efficiently kill the enemy was clear at a glance. Yu Hua looked serious, then took out the manuscript paper and pen, and began to carry out calculation verification, carefully reviewing each design parameter and partial design with the most stringent attitude.

Several months have passed since the idea of ​​electroslag remelting technology was proposed to the completion of the design scheme.

"Huh..." Hearing this result, Zhu Rui's tense mind finally relaxed.

This thing is a real shell. If a safety accident occurs due to wrong design parameters, it is very likely to cause dozens of casualties.

"Comrade Zhu, here, you have to pay close attention to the trial production of the sample bomb, and test and finalize it as soon as possible, so that we don't face the dilemma of having guns but no bombs." Yu Hua nodded, signed the end of the design plan with a pen in his right hand, then opened the drawer, and took out the Military Industry Bureau Equipped with an exclusive red seal, stamped on the signature position, and finally passed it to Zhu Rui.

"No." Zhu Rui shook his head again and again.

Yu Hua responded, "Please come in."

"Sir, the director asked you to return to the headquarters immediately, saying that Professor Zhuang's students are here." Lu Junyu pushed the door open and came to him quickly, bringing good news.

Professor Zhuang's students are here?

At this moment, Yu Hua and Zhu Rui's eyes suddenly brightened.
