Chapter 255 Industrial-grade air separation equipment!
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 to imitate.
And 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. Among the famous guns of World War II, the seemingly ordinary Chinese-style rifle 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-issue rifle in modern times, the Chinese 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 bullet and the 6.5×50mm full-power pointed bullet.
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 the official are first-rate. More importantly, the bullets used are the same as those 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 the base area which has a large amount of equipment built in Hanyang and is extremely short of material and financial resources, the Central Military Commission 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 Lian Zhu 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 Lian Zhu,
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 casually. It must be weighed and considered. The caliber of the bullets made by China and Hanyang are the same, and their performance is first-class. From the perspective of weapons universality and cost, there is no need to imitate the 7.62mm Shuilianzhu.
.
The shortcoming of the famous Mauser 98K 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 did not have the system dad to help him solve problems such as raw materials, equipment, technology and bullet yield rate without any worries, nor did he have any god-level tools to 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 for 1 million rifles.
Everything must be based on reality.
The current reality is that the base area has no money, no technology, no equipment, and there are people but very poor.
AK-47 is very good, but not suitable.
It is worth mentioning that although the Chinese-made, Hanyang-made and Czech-style calibers are common, the Chinese-formal and Czech-style can fire Hanyang-made 7.92mm round-nosed bullets, while the Hanyang-made ones cannot fire 7.92mm pointed-nosed 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 backward Hanyang-made rifle.
, becoming the new generation main firearm 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, and has stable and reliable firing. 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 is 60. This is Yu Hua's original plan target, 12.7mm large-caliber machine gun and 105 heavy grenade. There is no need to disclose it to the brigade commander yet, it is 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 expounding the feasibility suggestions and solutions to five technical problems. After writing, Yu Hua put it in an envelope, and attached it with the small coke oven and coking technology information he developed at random, as well as formal and 60-year-old sketches.
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, next time we agreed to meet at the eleventh big banyan tree, and next time it was agreed to be at 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 come to me for anything, you'd better 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 claimed to be an underground party student at Tsinghua University, and the identity logic makes perfect sense, this does not mean that Yu Hua would 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.
