The letter did not mention the specific rifle model, but said that there was a lack of rifle drawings and mortar weapons. Obviously, the situation was that the brigade commander, or the Red Army behind the Military Industry Bureau, had not yet decided which rifle and mortar to imitate. What caliber of mortar.
As a scientist employed by the organization, Yu Hua's suggestion was to launch a formal rifle and a 60mm mortar.
Yes, a formal rifle!
There is no fancy M-1 Garand semi-automatic rifle, and there is no ambitious AK-47 automatic rifle. The seemingly mediocre official rifle among the famous guns of World War II is a good match for the Eighth Route Army at this stage.
There are three reasons for choosing the official rifle. First, it has excellent performance. Second, it is consistent with the 7.92mm Hanyang caliber currently used by the Eighth Route Army, which puts less pressure on logistics. Third, the imitation technology and production requirements are not high.
As China's first standard rifle in modern times, the official rifle has undoubtedly excellent overall performance. It uses 7.92×57mm full-power pointed bullets with a muzzle velocity of up to 810 meters per second and an effective range of about 1,000 meters.
In terms of range, the Type 38 rifle has an effective range of about 460 meters.
In terms of power, if you compare it with your toes, you can see the difference between the 7.92×57mm full-power pointed bullets and the 6.5×50mm full-power pointed bullets.
In terms of accuracy, Japanese rifles are famous for their high accuracy, and the intermediate and formal rifles learned from Master Mauser have higher accuracy. You know, back to 30 years ago, most of the rifles in the world were called Mauser series.
The three core indicators of China's official rifles are first-rate. More importantly, the bullets they use are compatible with bullets made in Hanyang, Czech machine guns and Maxim heavy machine guns. This is very important. Common bullets mean less logistical pressure.
In addition, this gun also incorporates a universal design concept into the interior. Some bolt parts can be directly interchanged. The internal structure is simple and the process requirements are not high.
Compared with the 7.62mm large eight-grain Garand and Shui Lianzhu, or the most legendary 98k, China Official is not as well-known as the other, but its performance is definitely not bad.
For a base area with a large amount of equipment built in Hanyang and extremely short of material and financial resources, the Zhongguan Formation is a perfect match.
"The Chinese official rifle may not be the best, but it is the most suitable." Yu Hua took out a piece of paper, picked up a pencil, and quickly sketched a conceptual sketch of the Chinese formal rifle.
Many times, the best may not be suitable for you.
The disadvantages of the m1 Garand are its complex structure, high cost, and high cost of use.
The Shui Lianzhu is a classic and good gun, but the 7.62mm caliber is very embarrassing for the bases that use Hanyang-made rifles as their main rifles. Since it is not common with the main rifles, and there is no performance difference between the Chinese official and the Shui Lianzhu, The performance advantages of Shui Lianzhu are simply not enough to overwhelm the cheap and affordable mid-range models, making it the objective first choice.
Weapon production is by no means something that can be decided just by thinking. It must be weighed and considered. The caliber of bullets made by China and Hanyang are the same, and their performance is first-class. From the perspective of weapons generality and cost, there is no need to imitate the 7.62mm Shuilianzhu. .
The shortcoming of the famous Mauser 98k gun is the cost, because in a sense, the Zhongguan is actually an alternative 98k. The two rifles have noble and elegant German origins. The manufacturing cost of a genuine 98k is almost as much as 2 is the official number.
Is this business worthwhile?
Of course it's not worth it.
As for the famous ak-47, this world-class gun is suitable for all current industrial countries, but it is not suitable for base areas.
A base area with almost zero industrial technology can neither build nor use it.
Yu Hua didn’t have a system dad to help him solve problems such as raw materials, equipment, technology, and bullet yield without any worries. He also didn’t have any god-level tools that he could buy and sell in one fell swoop to build a production line with an annual output of 100 million rounds of bullets and a production line with an annual output of 1 million rifles.
Everything must be based on reality.
The current reality is that the base area has no money, no technology, and no equipment. There are people but very poor.
The ak-47 is very good, but not suitable.
It is worth mentioning that although the Chinese, Hanyang and Czech calibers are common, the Chinese and Czech can fire Hanyang-made 7.92mm round-nosed bullets, while the Hanyang-made ones cannot fire 7.92mm pointed bullets.
Soon, Yu Hua drew a conceptual sketch of the official rifle. If the base adopts his suggestions, then this excellent rifle, which has been processed by German machine tools and processed by a vertical deep hole drilling machine to ensure quality, will replace the Hanyang-made rifle with backward performance. , becoming the new generation of main firearms of the Eighth Route Army.
In terms of mortars, the 60mm mortar is most suitable for the lightly-armed Eighth Route Army. It has high mobility, is easy to carry, has stable and reliable firing, and the TNT explosive gives the shells high lethality.
The most important thing is that the cost is low and the manufacturing difficulty is low.
Officially, the target was 60, which was Yu Hua's original plan. The 12.7 mm large-caliber machine gun and the 105 heavy grenade were not necessary to be disclosed to the brigade commander for the time being. It was not yet time.
The model can be determined first, and when it comes to the actual gun-making process, wait until the German machine tools arrive on the sea.
After drawing a conceptual sketch of the 60mm mortar again, Yu Hua opened the drawer, took out a piece of letter paper, and began to write a reply.
To Chen:
Hua has received...
He wrote thousands of words eloquently, carefully elaborating on the feasibility suggestions and solutions to five technical problems. After writing, Yu Hua put it in an envelope, and then attached it with the small coke oven and coking technology information he developed at random, as well as sketches of medium-sized and 60-year-olds. Concept map, get up and go downstairs, heading towards the west gate of the school.
None of the five major technical problems can be solved overnight.
The campus was as quiet as ever. Yu Hua walked through the campus, went out from the West Campus gate to the right, came to the seventh big banyan tree and stood there, waiting quietly at the scheduled meeting point.
This time we agreed to meet at the seventh big banyan tree, the next time we agreed to meet at the eleventh big banyan tree, and the next time it was the thirteenth.
Each scheduled meeting location is incremented by a prime number to improve safety as much as possible, which is Yu Hua's request.
Three minutes later, a familiar figure arrived as promised. It was Yang Xiu.
"Mr. Yu Hua." Yang Xiu said respectfully, but his eyes revealed a hint of surprise and surprise. He didn't expect Yu Hua to appear so soon.
Yu Hua smiled and nodded, handed the envelope he carried with him to Yang Xiu, and said, "There are things Mr. Chen needs here, including a copy of coking technical information, rifle models and mortar models. Give them to Mr. Chen as soon as possible."
"Yes." Yang Xiu was very surprised when he heard this, and quickly took the envelope without asking.
"By the way, do you know Luo Peng?" Yu Hua continued to ask.
Yang Xiu immediately responded: "I know him. I asked him to give the letter to you."
"That's good. I'll go in first. If you need anything, you can still use this method." After confirming Luo Peng's identity, Yu Hua lowered his guard, smiled, left a word, and turned around to leave.
Although Luo Peng claims to be an underground party student at Tsinghua University, and the identity logic makes perfect sense, this does not mean that Yu Hua will trust him 100%.
Some things are best verified.
It has nothing to do with trust, because your own safety is above all else.
Watching Yu Hua enter from the school gate, Yang Xiu carefully observed both sides of the street to confirm that no one was secretly monitoring or following Yu Hua, and then left quietly.
Returning to the nuclear physics laboratory, Yu Hua went directly upstairs to deal with the final aspects of the oxygen lance development work, striving to complete it within today, and then enter the research stage of industrial-grade air separation equipment.
If the difficulty of research and development of oxygen lances is about 10, the difficulty of research and development of industrial-grade air separation equipment reaches 30, which is exactly three times. For this era, industrial-grade air separation equipment used in steel smelting is properly ranked among the cutting-edge machines. Level has an irreplaceable role.
