The person who came was a very smartly dressed man, about thirty years old, with square glasses and short hair. At first glance, he looked like the kind of engineer who was a commanding officer on the front line.
As far as growing and tying hair is concerned, this was a way to distinguish between different ethnic groups in the classical era. It can be said to be a manifestation of the distinction between Huayi and Huayi. Since the Zhou Dynasty, growing and tying hair has become popular in China, with disheveled hair. Disappeared.
At present, the imperial court has not done much coercive intervention in this regard. The official document issued by the Ministry of Rites only states that it is not appropriate to wear hair disheveled in public.
Therefore, the current overall trend can be said to have evolved naturally in line with industrialization. The custom of hair binding is still common in rural areas; in urban areas with developed economies and faster pace of life, many workers choose to cut their hair short for convenience. , there are also young people who pursue fashion and freshness trying new hairstyles.
Young people with dyed and permed hair... Zhou Changfeng had also seen them on the road, but in his impression, these would probably inevitably lead to scolding by their family members.
As for the capable engineer in front of him, he obviously belongs to the convenience type.
"It's really Commander Zhou. When I heard the name, I didn't think it was the same name. It turned out to be true." He cupped his hands and said with a smile: "I saw the sketch you drew. It's very interesting. I didn't expect that besides the battle, Besides, you also know weapons."
"Just...a little bit." Zhou Changfeng chose to tell the truth.
"Mr. Zhou, you are too humble. I am Wang Huan'an from the Public Works Department. Let's talk?"
"good."
So they both sat down, one on the left and one on the right. In the middle was a square walnut table with several pieces of sketch paper on it.
"You have personally led troops to fight against tanks. Your opinions on this anti-tank battle must be weighty. Do you think grenades and grenades are not enough?" Wang Huan'an asked straight to the point.
"That's for sure. Infantry is at a natural disadvantage against armored targets, just like infantry and cavalry in ancient times. Although there are ways to control cavalry with foot, it is not efficient after all." Zhou Changfeng drew a circle on the sketch and continued Dao: "Therefore, the more anti-armor weapons the infantry troops have, the better."
Wang Huanan nodded thoughtfully and said: "Nowadays, the hit rate of rifle grenades when attacking moving tanks is too low, and the range is only a hundred meters; grenades are almost close to hand-to-hand combat, and a longer and more powerful one is really needed. Light weapons."
As countries around the world are developing anti-tank ammunition based on the Monroe effect, Ming Dynasty is naturally not idle either. In order to keep it secret and confuse the public, the name of the hollow-charge armor-piercing ammunition is called "special incineration ammunition."
The Ordnance Administration has officially issued research instructions to major arsenals last year. Major military industrial bases such as Yingtian, Shuntian, Wuhan, and Chengdu have conducted research and development in accordance with the given technical indicators. They will conduct unified evaluations when the deadline is reached. The one with the best overall performance is selected.
The Ordnance Bureau's research instructions are anti-tank grenades and anti-tank mines. Although the Type 35 anti-tank guns have just been installed, it is necessary to prepare for a rainy day.
What's more, according to known intelligence, the frontal armor of Tsarist Russia's medium-sized tanks is more than one inch thick, and the side armor is more than half an inch thick. This is no longer something that combat anti-guns can effectively deal with, and the infantry troops are in urgent need of weapons that can damage it.
Now a year has passed, Yingtian Arsenal has completed its own design and has gone through many tests and improvements.
Therefore, Wang Huanan didn't care about the sketches of rifle grenades and hand grenades drawn by Zhou Changfeng. What interested him was the tubular launcher.
He narrowed his eyes slightly and imagined the appearance and principle of this thing in his mind. "The recoilless rifle is still a new thing now. Commander Zhou, you can actually think of using its principle in other places. How wonderful."
The prototype of the recoilless rifle appeared more than 20 years ago, but so far, there has not been a large-scale model installed.
In history, there was an engineer named Kurchevsky who was extremely enthusiastic about recoilless rifles. He designed a series of recoilless rifles ranging from 37mm to 305mm, ranging from small to large, but without exception they were all useless. His most famous design was a giant 305mm recoilless gun installed on a destroyer, but the test results were poor.
So during the cleaning period, because the designed weapons were too poor and he was implicated in other cases, Kurchevsky was arrested and later fed peanuts.
Zhou Changfeng spread his hands and said, "Theoretically it should be feasible, but I am just an amateur after all. Whether it will work or not depends on the actual test."
"I am very optimistic about this design. Really, the so-called brainstorming does make sense. This thing is completely feasible and wonderful."
"So...then it counts as accepted?"
Wang Huan'an, who was holding the tea cup, smiled and said: "At least this has given us a lot of inspiration, but the specific details need to be adjusted separately."
Zhou Changfeng nodded and said thoughtfully: "This thing combined with hollow charge technology can destroy thickly armored targets at a distance of dozens of steps. Not to mention today's thin tin cans, even the cutting-edge tanks in the next few years are expected to be able to destroy them." There is no way to effectively defend. If there is a war, our army will have an advantage in this regard at the beginning."
"It's true. Compared with solid group charges, the hollow-charge ammunition's ability to penetrate steel plates is extraordinary. A thing the size of a small orange can penetrate more than an inch of manganese steel with a soft iron cover." Wang Huan'an recalled. After looking at the scene of a certain test some time ago, he said with emotion: "And it has just started now. This kind of ammunition will definitely be developed in the future."
"Ah ha? Soft iron?" Zhou Changfeng was a little surprised. He blinked and asked, "Is it a slip of the tongue? Soft steel, right? Use soft iron as a medicine cover?"
"It's just a casual comment. I did some tests a few days ago. I tried covers made of various metals, such as cast iron, soft iron, soft steel, hard steel, zinc-aluminum alloy, brass, copper, etc." Wang Huan'an waved his hand, "But I can't disclose the specific situation, sorry."
Zhou Changfeng smiled slightly and made a joke, "Theoretically, the higher the density, the better the effect, so have you applied for gold to do this?"
"Uh..." Wang Huan'an laughed dumbly, and then said seriously: "Sir Zhou, we can't afford gold, but we have tried silver."
Regardless of other factors, if the variables are controlled, the higher the material density of the medicine cover, the better, zinc-aluminum alloy < steel < copper < silver < gold.
So...eat a golden armor-piercing bullet from me!
However, considering the cost-effectiveness, people generally choose copper as the material of the medicine cover. Of course, in order to reduce production costs, low carbon steel is also used.
As for why the dense and cheap lead was not chosen as the medical mask, it was because the texture of lead was too soft and the melting point was too low. It would easily disperse and vaporize when forming a metal jet, and its armor-piercing efficiency was only two-thirds of that of copper.
