"Brother Biao, what big thing are you going to do again?" Shen Yang's eyes through the lens were full of expectations. This made Yu Biao a little curious. In fact, this is normal. Staying in this valley and dealing with iron, steel and weapons all day long. It is understandable to find something else to adjust it.

"It's hard to say now." Yu Biao smiled faintly and reached out to pat Shen Yang on the shoulder. "I'll just ask you two. Will you be willing to do it with me then."

"I can't say it clearly." Du Zaijun sighed and pretended to be helpless. "Forget it. Anyway, I'll do it with you to the end. As long as I'm not bullying men and women, I'll follow you."

“你说这话就该揍.”余飚冲着杜在军挥了挥拳头.“把我当成什么人了.不就是把你们的梦中情人变成了我媳妇儿吗.要说这事也怪你们.不早下手.现在后悔了.嘿嘿.人家都快变成孩儿他娘了.”

"This is wrong. Although we like Li Ruping, it doesn't mean that way." Shen Yang explained: "Why did the Huns be destroyed? We were determined not to be slaves of the country at that time. We had to devote ourselves to the vigorous cause of saving the country."

"Little glasses. You're pretty noble." Yu Biao looked disbelieving, but he turned to the point. "Stop talking about it being useless. The Japanese have transferred the armored troops. You won't let me hit my head."

"It's definitely not possible to hit the head. If you use your unique weapon, you might be able to poke two holes." Du Zaijun smiled and handed a report to Yu Biao.

In fact, although Du Zaijun was joking, there were examples of armored vehicles being destroyed by cold weapons. China once purchased a large number of CV-33 tanks from Italy. The reason was that the price was cheap. I only realized that this armored vehicle was actually smashed and destroyed by tribal warriors with big axes and hammers in Ethiopia.

This report is a detailed list of anti-armor weapons produced by the arsenal. It can be said to be top-secret materials. Among them are anti-tank grenades, directional mines, etc., which Yu Biao is most concerned about. There is even a bazooka incident that surprises him.

Rocket technology has a long history of development in China. In the 26th year of Wanli in the Ming Dynasty (1598), a rocket launcher called "Rocket Liu" made by Zhao Shizhen can give rockets a certain direction and angle of shooting. It is the prototype of modern rocket launcher.

The bazooka is lightweight, low in cost, easy to use, easy to mass production and equipment. Since World War II, it has been one of the main weapons of infantry short-range anti-tank operations.

Anti-tank bazooka first appeared during World War II. At that time, there were two types: one was the 60mm M1 rocket-type bazooka equipped by the United States in 1942. American soldiers were very similar to a trumpet-shaped instrument called "Bazouka". This commonly known as "Bazouka". Later, it became a common name for bazouka in Europe and the United States. "Bazouka" uses a steel launcher that opened at both ends and is produced by a rocket engine inside the bullet. The thrust drives the rocket movement. The gunpowder gas discharged from the engine is sprayed out from the back of the barrel, making the weapon have no coaxial force. Another type is the "Iron Fist" coaxless gun-type bazooka equipped by Germany in 1943. It fires a 150mm super-caliber armor-breaking bomb. It relies on the gunpowder gas pressure formed by the combustion of the steel launcher opened at both ends. It promotes the movement of the bullet body and uses the reaction force generated by the spraying of gunpowder gas from the back of the barrel to eliminate the recoil of the barrel.

However, when Yu Biao couldn't wait to hold the "bazooka" made by the arsenal in his hand, he was a little disappointed. Although it looked like the schematic diagram he drew, the weight obviously exceeded his expectations.

"There is no seamless steel pipe suitable for the caliber. This is wrapped by a stupid method." Du Zaijun explained: "At present, there is only one sample. After the test-fire, the arsenal believes that it is very difficult for individual soldiers to carry and fire. It is better to produce more hollow-loaded grenades."

"And the rockets we manufacture are powered by gunpowder jets. After many experiments, we think this is absolutely problematic." Shen Yang continued: "To meet the standard you mentioned, rockets should be propelled with small engines. This technology is also at the forefront of the international level. At our current level, it cannot be achieved at all."

Yu Biao's eyes were straight and his face was a little hot. Unexpectedly, it was like this. What he had imagined was just a monkey through the sky. It would be too ugly if he didn't know how to do it. Now he was ugly. He thought that the rocket launcher was just a hollow iron tube. Unexpectedly, the key was not the cylinder, but the bullet.

This is true. Rockets usually consist of three parts: warhead, rocket engine and stability device. The warhead includes fuse, rocket shell, explosive or other loadings. Rocket engines include ignition systems, propellants, combustion chambers, nozzles, etc. The tail rockets maintain flight stability by the tail wing; the turbo rocket relies on the gas sprayed from the inclined nozzle, causing the rocket to rotate at high speed around the bullet axis, creating a gyroscope effect, and maintain flight stability. At that time, only the United States and Germany had the technology of mini rocket engines. The British also wanted to do it. In the end, they could only create a spring-launched pseudo-rocket. The advantage was that they could be fired at will. They could also be used indoors. They were not afraid of airflow backlash. The disadvantage was that the hit range was terrible. They could only use it.

Seeing Yu Biao's eyes straight and his face changed, Du Zaijun comforted him: "Brother Biao, we can't figure out this rocket launcher. But the range of grenades has been greatly improved. We have already figured out the principle of hollow charge. It uses the Monroe effect."

Install a conical metal cover at the front of the warhead. The cone mouth is facing forward and the tip is facing backward. The metal cover is loaded with explosives behind it. The front is empty. When the warhead explodes, the metal cover is melted into a high-speed liquid metal jet at high temperature. It focuses on the center of the hollow part like a lens. It shoots the armor of the enemy tank. It rushes the armor out of a hole and damages the equipment and personnel inside. This is like using a high-pressure faucet to rush out a hole on the sand pile. This technology is said to be first invented by Switzerland and later sold to the United Kingdom and the United States.

"So. It is more than enough for the current Japanese armored forces. The armor-piercing grenades are more than enough. Moreover, the modified burning grenades and fragment grenades are also effective after testing." Shen Yang added.

"That's good. That's good." Yu Biao smiled in disbelief and said, "Aside from the outside is a good person. Sooner or later, he will reveal his feelings. Now he will be embarrassed in front of the experts and hurt his self-esteem. I'm sorry, I begged my grandpa to sue her grandma and look for seamless steel pipes everywhere."
