my scientific age

Chapter 310 Goodbye, Moscow!
The sound of metal and metal crashing in the machining workshop was one after another, and seven of the oldest and most skilled workers naturally took over the responsibility of the basic production unit of hand-loaded ammunition, running the entire production line.

At the beginning, everyone was a little unfamiliar because they had not been exposed to this manual stamping production method. Under the careful guidance of Zhuang Qianding, the seven workers quickly became familiar with the skills and experience after hammering again and again. .

The second 7.92mm fixed-load bullet took 8 minutes to complete the entire manufacturing process, and the third bullet took a sharp drop of 2 minutes, which was the same as the first bullet made by Zhuang Qianding.

The higher the experience and craftsmanship, the faster the production.

When the fifth bullet was reached, the production speed of the seven-person production line had already risen a step, and the time taken for a single bullet had been shortened to 5 minutes and 30 seconds.

The sixth, 5 minutes and 20 seconds.

Seventh, 5 minutes and 10 seconds.

Eighth, 4 minutes and 55 seconds.

With the breakthrough of the 5-minute mark, the seven workers who were already sweating in the sweltering heat became more and more enthusiastic and full of energy. Everyone did not slack off, and all operated at the highest efficiency.

They know very well what they are doing, this is the most precious brand new bullet produced for the troops!

Since the Long March, the ammunition of the troops has been extremely scarce and cannot be supplied at all. Due to the lack of relevant technology, the reloaded ammunition has to be used as a last resort. As a result, the original ammunition is very precious and is generally only used by sharpshooters and veterans.

Recruits who use reloaded bullets often have inaccurate shots on the battlefield, resulting in defeat in battle.

It has to be said that this is a disgrace to the soldiers and workers.

Now, with this tool, it is possible to realize the production of new fixed ammunition, how precious is this opportunity?

The seven did not dare to slack off.

Lin Wan stood next to the production line, holding a pencil in her hand, constantly recording the production time of each bullet and the technical essentials of the production process. These production data are extremely precious, so a set of production standards suitable for hand-loaded ammunition can be summarized.

She clearly remembered what Yu Hua said, the standard is the most important.

"This kind of production line can be replicated. I suggest that the Military Industry Bureau re-install the bullet production line, and remelt all the collected brass bullet casings to roll brass plates. In addition, the mining and smelting of Jingbian Copper Mine is accelerated. The supply of copper materials must follow In fact, one ton of copper can produce 1.6 tons of brass, which is equivalent to 11 rounds of ammunition based on 14.5 grams of bullet casings, jackets and base fire seats." Zhuang Qianding looked at the steel and brass plates that were constantly being consumed in the production line, and took back With his eyes, he handed the five rounds of bullets that were confirmed to be qualified by the quality inspection in his hand to Chen Kang beside him, reminding him.

The manual fixed-loading ammunition production line has been established, and the next step is to train personnel, manufacture equipment, replicate the production line, and exchange manpower for output.

However, the core issue must not be ignored, that is, the supply of raw materials.

Once the production line of manual custom-loaded ammunition is laid and developed to a certain scale, the supply of copper must be guaranteed.

Moreover, there is no point in continuing the reloading operation when it is already possible to produce custom cartridges. Instead, it is better to remelt the cartridge case and roll the brass plate.

"I'll arrange it right away. The Jingbian Copper Mine has already started mining and smelting. Brass will be delivered soon. You can rest assured." In response, he had already made a decision in his heart to immediately stop the production of reloading bullets.

"Director Chen, do you have a gun? I haven't shot a gun since I returned to China. I had a good time today. I checked the performance of the bullet by the way." Zhuang Qianding continued to ask.

"Of course." Chen Kang nodded.

The production of bullets in the workshop continued. Zhuang Qianding and Chen Kang left and went to the north of the arsenal to find a wasteland, planning to clear the surrounding area for a temporary shooting range, and then found an [-]% new Hanyang-made rifle from the guards. Do a bullet test.

The content of the entire bullet test is simple, mainly to detect whether the bullet has problems such as jamming and ejection, as well as basic parameters such as whether it can be fired normally and shooting accuracy. Ballistics tests such as extremely professional bullet initial velocity measurement cannot be carried out due to limited conditions.

Zhuang Qianding stands in the center of the shooting range, and there are three gun targets in total, 50 meters, 100 meters, and 200 meters.

There were four guards who belonged to the headquarters guard regiment. They were sharp-eyed and found five bullets in Zhuang Qianding's hand. These bullets looked very new, with a bright yellow surface and extremely smooth surface. They were newer than the bullets they carried. many.

Looks extremely tempting.

"Squad leader, these bullets look so new..." As the owner of the original gun for the bullet test, the young guard couldn't help but said to the squad leader beside him.

"Keep quiet." The monitor signaled to shut up and not to violate discipline. Even so, his eyes were fixed on the bullet in Professor Zhuang's hand.

"I only hit 50 meters, 100 meters and 200 meters will be handed over to you, and everyone will experience it together." Zhuang Qianding held Hanyang made, and while loading five bullets with Liushugou made labels into the funnel magazine, he pointed at Chen Kang Said to several guards around.

Hearing these words, the squad leader and the three guards suddenly lit up.

"You please." Chen Kang smiled.

When the reload is complete, pull on the big bolt.

Zhuang Qianding holds the Hanyang made with both hands, showing the most standard gun posture, aiming the dark muzzle at the 50-meter gun target, locking the target, and pulling the trigger.

The whole process is done in one go and takes two seconds.

During his studies in the United States, Zhuang Qianding often came into contact with firearms, whether it was a shotgun or a revolver, including the Springfield rifle in active service in the US Army.

"Bang!" The striker fired the primer, which exploded and ignited countless nitrocellulose particles in the cartridge case. The metal bullet with a real diameter of 8.2 mm rotated at a high speed and was embedded in a 7.92 mm barrel. Perfect interference fit.

In a blink of an eye, the entire circular metal warhead shot out with a muzzle velocity of 640 meters per second, spanning a short distance of 50 meters, and accurately hit the middle of the bull's-eye.

Hit the bullseye with one shot at 50 meters.

Seeing this scene, Chen Kang and the four guards were a little surprised. They didn't expect Zhuang Qianding's marksmanship to be so good.

From a language point of view, 50 meters is a very short distance. From a practical point of view, it is already difficult to shoot mechanically at a gun target 50 meters away.

Looking at the gun target, Zhuang Qianding withdrew his gaze, pulled the bolt back with his right hand, and Huang Cancan's bullet casing exited the gun barrel, a faint smell of gunpowder smoke filled the air.

The entire ejection process is easy and unobstructed.

Careful observation of the loophole clip and the internal conditions of the gun chamber showed that there was nothing abnormal. Zhuang Qianding nodded with satisfaction: "For the time being, there is no problem of jamming and difficulty in ejecting the shell. The accuracy of the bullet is good. Director Chen, you can try it."

When the voice fell, he handed the Hanyang made in his hand to Chen Kang.

"Okay." Chen Kang nodded, took the rifle, pulled the bolt and aimed at the 100-meter target, his eyes narrowed.

"boom!"

A few seconds later, crisp and loud gunshots spread throughout Liushugou, and the high-speed spinning metal bullet flew along a predetermined trajectory and accurately hit the center of the 100-meter gun target.

After the shooting, Chen Kang pulled the bolt, and the cartridge case was withdrawn. Looking at Huang Cancan's gold-like cartridge case, his eyes were full of satisfaction and comfort.

How to see, how pleasing to the eye.

After two shots, the sound of gunfire has already attracted the workers around the arsenal, who gathered here to watch curiously.

"How do you feel?" Zhuang Qianding greeted him and asked about the customer's experience.

"Satisfied, very satisfied, it plays better than the original ammunition we used." Chen Kang repeatedly praised.

Zhuang Qianding nodded: "Continue testing to see how the 200-meter target works and whether the accuracy can be maintained."

Hearing these words, Chen Kang did not object, and immediately handed the rifle to the owner of the original gun: "Xiao Zhou, you are a sharpshooter of the guard regiment, you come to shoot at a 200-meter target, and you have three rounds left."

"Yes!" Zhou Rui, a security guard who had been waiting for a long time, hurried forward and took over his Hanyang made with joy on his face.

Regardless of his youth, with this Hanyang-made gun in his hand, he has already set a shooting record of [-] enemies. He is one of the three sharpshooters of the Headquarters Guard Corps. If it weren't for his excellent marksmanship, he would not be able to serve as Professor Zhuang's personal guard. .

Under the gaze of everyone, the guard Zhou Rui looked confidently at the 200-meter gun target, holding a familiar rifle in his right hand, and locked the center of the gun target through the gap in the mechanical sight with sharp eyes like an eagle.

"Bang! Bang! Bang!" Three gunshots rang out one after another, and they accurately hit the straw gun target 200 meters away, with three bullet holes evenly distributed in the center.

After Zhou Rui finished shooting, Zhuang Qianding and Chen Kang came to the 200-meter gun target to check the bullet holes.

"The accuracy of firing hand-loaded ammunition is about 4.5 MOA. I remember that the shooting accuracy of the Hanyang 4-type rifle is [-] MOA. Considering the barrel rifling wear and the production quality of the original gun, this accuracy is already very good. Overall For the time being, there are no problems such as jamming of the hand-loaded bullets, and the performance is still very good. Director Chen, what is the shooting accuracy of the reloaded bullets?" Zhuang Qianding looked at the three shooting bullet holes and drew a circle in the center. After a simple calculation, the shooting accuracy of this Hanyang-made hand-loaded ammunition was obtained, and the evaluation said.

4.5 MOA, which is 4.5 arc minutes, which means that at a distance of 100 meters, the bullets will be evenly distributed in a circle with a diameter of about 13 cm.

This shooting accuracy is definitely far inferior to the bolt-action rifles equipped by countries around the world. After all, the average accuracy of 3 meters is as high as 2.5MOA, and some guns can even reach [-]MOA, but it is much better than the reloaded bullets used by the Red Army.

"I haven't calculated it, basically if it exceeds 200 meters, it's almost impossible." Chen Kang was a little embarrassed. They didn't calculate this kind of shooting accuracy parameter that needs to be mathematically calculated.

"That's it for now. The shooting accuracy of the Hanyang-made rifle is 4 MOA, and the shooting accuracy of the Type 2.5 Arisaka rifle is about [-] MOA. ." Zhuang Qianding sighed.

The 3-meter shooting accuracy of the official rifle is about [-]MOA. Although it is not as good as the [-]-type rifle, at least there is no generation difference in accuracy.

Yes, generation difference.

Hanyang is still lingering in the fourth, and the 2-type rifle has broken through the third, entering the 3-[-] MOA [-]-meter accuracy range, which is an irreparable gap.

The bullet test came to an end, and soon, the test results were handed over to Chen Kang in written form, and then Chen Kang went to the cave in person to report the situation with the report on the manual loading and test results.

……

Moscow, suburbs.

As the world's top radio research institution, the Academy of Communications of the Soviet Union is located in a house with a classical temperament, next to the Moscow River. Standing on the third floor, you can overlook the Red Square building in the city center.

In summer Moscow, the climate is warm and comfortable, without the cold of winter.

In the Academy of Communications, there is a statue, which is the father of radio Alexander Stepanovich Popov. In the hearts of countless Soviet people, the father of radio in the world is not Marconi, but forever Popov.

Because of this, the Academy of Communications has a statue of Popov to commemorate Popov's great contribution to the field of radio.

The gate of the Academy of Sciences.

A group of Soviet radio experts gathered here. Looking around, any one placed outside is a top-level scholar that is enough to excite people, and they are here today for only one purpose - to see them off.

There was an oriental face in the crowd, wearing glasses and a suit. He was gentle and refined with the temperament of a scholar. This person was the only foreign professor in the entire Academy of Communications.

"Li, it's a pity I can't study electromagnetic waves with you. From the dean's point of view, I don't want you to go back, but from a personal perspective, I support you to go back and help your motherland." Dean Ivanov looked at Li Qiang, with reluctance in his eyes, said slowly.

Li Qiang, who is from Oriental China, has been ranked in the top radio expert club of the Soviet Union and has his own place in the field of communication.

If it wasn't for his superior's request, he really didn't want to let Li Qiang go back. One was because of Li Qiang's talent and strength, and the other was because of Li Qiang's future.

Staying in the Soviet Union, Li Qiang will have a very good platform to get in touch with the most cutting-edge and advanced science and technology in the world.

Unfortunately, a war broke out in Li Qiang's motherland, and the Japanese were invading China. For Li Qiang's request to return to China, even if Ivanov was reluctant, he had to agree.

"Thank you for your support, and thank you for your help and dedication. I have no choice but to return to China." Li Qiang knew what it meant to return to China, but he did not regret it. He turned his back to the door and was facing the Academy of Communications Science, his face revealed Free and easy smile, nod to thank.

"Li, goodbye, take care all the way." Ivanov took a deep breath, stepped forward, and hugged Li Qiang gently.

"Dean, professors, goodbye." Li Qiang and Dean Ivanov hugged each other, then let go of them naturally, saying goodbye to the other six top radio experts who were professors.

After he finished speaking, he turned to leave the Academy of Communications and got into the car parked at the door.

Next, he will take the train to St. Petersburg and return home by ship, a journey of [-] kilometers, passing through the European and African continents.

Back home.

Go back to help the motherland that was invaded by Japan.

Li Qiang stared at the Moscow scenery outside the window through the car window. He knew that he might not come back for more than ten years after he left.

Goodbye, Moscow.
