"Hey, Wang!" Skinner entered the office and saw Wang Xuexin, so he stepped forward and greeted him enthusiastically: "It's a pleasure to work with you. We have learned a lot during this time. But now..."
As he spoke, Skinner spread his hands and said with regret, "It's time to say goodbye."
"Have you completed the rocket launcher project?" Wang Xuexin asked.
"You can say that!" Skinner replied: "After fully studying the design of your rocket launcher, we have corrected a series of shortcomings of our army's rocket launcher. I believe it is ready for use on the battlefield."
After a pause, Skinny continued: "But I think it is still necessary for our army to equip the rocket launcher you designed. Because our rocket launchers always have a problem that cannot be solved, that is, they are too bulky. So your super-caliber rocket launcher is simply
It’s a genius design. We can’t surpass it in this regard!”
The so-called "super caliber" refers to the design in which the Mao Xiong rocket launcher ammunition exceeds the barrel.
Skinny is right, the advantage of this design is that it is small in size, light in weight and very easy to carry.
This is very important for individual weapons, which is one of the reasons why the Bear rocket launcher can be widely equipped in third world countries and guerrillas.
On the contrary, Yingjiang's rocket launcher...it is a bazooka rocket launcher to be precise. It follows the conventional idea, that is, the shells are installed in the barrel.
This inevitably has the disadvantage of being large in size, heavy in weight, and inconvenient to carry. This shortcoming will cause problems in charging, marching, and logistics. For example, a car can transport fifty bazookas and at least a hundred rocket launchers.
, the same is true for airdrops.
However, this shortcoming is not a big problem for Yingjiang... The most important thing for Yingjiang is logistical supplies.
At most, you need to plan when airdropping.
Of course, the airdrop must transport as much equipment as possible to the airborne troops, so it is not cost-effective to use the bazooka. In this case, you can consider using a rocket launcher instead.
Wang Xuexin didn't care about this, he just wanted to find an excuse to keep Skinner.
After thinking for a while, Wang Xuexin said: "That's not what I care about, Skinny. Our rocket launcher has a penetration depth of only 60mm. This may be enough on the Chinese battlefield, but on other battlefields..."
Skinner nodded.
What Wang Xuexin said was indeed the problem that Yingjiang needs to face. Yingjiang has to face not only the Japanese but also Hans on the international battlefield.
At this time, Hans's Panzer IV had increased its armor to 50mm.
It is difficult for a 60mm penetration to penetrate 50mm sloped armor frontally, so the rocket launcher cannot pose a threat to enemy tanks, and it is difficult for the rocket launcher to attack enemy tanks from the side and rear...
Rocket launchers are different from anti-tank guns.
Anti-tank guns have a long range and can be hidden on the flanks of the enemy's offensive line to attack targets from the side.
The range of the rocket launcher is only a few tens of meters, and it is difficult to hit the target due to the excessive wind deflection of about 100 meters. If it can attack the target from the side and behind... then it can only be done if the enemy follows the infantry to death.
arrive.
But Skinner didn't care.
"This is one of the reasons why I am in a hurry to return to China, Wang!" Skinner replied: "I think the penetration depth of this rocket launcher should be much more than 60mm. The reason why it is only 60mm is because the triggering time is not in the focus, but must be precise.
To set the triggering time and distance on the focus, you should go back to China and use precision instruments to do it! And you guys..."
Wang Xuexin admitted that Skinny was right. It was difficult to produce focus-triggered rockets under the conditions of the Eighth Route Army.
He originally wanted to use this reason to keep Skinny here, but he didn't expect that this was the reason for Skinny to return home.
Skinner thought that Wang Xuexin was worried that he would not give the technology to Wang Xuexin after he developed a new warhead, so he added: "Don't worry, Wang! One day we find a way and we will share the technology with you. We have something in common."
Enemy, isn’t it?”
Wang Xuexin could only nod his head and said: "Okay, happy cooperation! I hope we have a chance to cooperate next time!"
"Of course!" said Skinner.
Just as Skinner was about to turn around, Wang Xuexin said: "Skinner, we are focusing on this issue. I think we should change our thinking."
"What idea?" Skinner turned around in confusion.
During this period of time, he has thought about various methods, but all kinds of experiments and attempts have failed... You must know that when the cone-shaped charge of the rocket launcher explodes, the focus is only one point. During the flight time,
It is almost impossible to accurately grasp the focus of the armor surface at such a fast speed.
At this time, he did not believe that Wang Xuexin had any ideas.
Or even if there is an idea, it should be an idea that he has tried.
"That's right!" Wang Xuexin knew what Skinny was doing during this period. He said: "I think we have been trying to change the distance and ensure the stability of the gunpowder column to focus as much as possible. This accidental factor is too great."
If the gunpowder column is stable enough, the speed of the rocket launcher can be guaranteed as much as possible. Only by obtaining a stable speed can we calculate the appropriate time to trigger the rocket. In addition, the delay time and precision of the fuse must also be considered.
Any slight discrepancy in all these things will cause the rocket to be out of focus and suffer from insufficient penetration.
But even so, the rocket launcher will still encounter headwind and tailwind problems... These will change the speed of the rocket launcher.
Therefore, strictly speaking, this speed is actually uncontrollable or "unpredictable".
"I know this!" Skinner asked. "Do you have a solution?"
Wang Xuexin said: "If we do not use ordinary fuses, but use pressure fuses... What I mean is that when the rocket hits the hard armor of the target, it will inevitably generate a certain amount of pressure. If there is a certain kind of fuse, it can reach a certain level.
The rocket detonated in a moment of pressure. I think the focus is what we can control!"
Sun Erwei was confused when he heard this, but Skinner's eyes widened, and then he was so excited that he couldn't speak incoherently: "My God, you are such a genius, Wang! Why didn't I think of this? If we use a pressure value
By detonating, you can completely ignore those uncontrollable or difficult-to-control factors, all of them! Instead, we only need to test the focus pressure value! God, you are right, King! You are right!"
What Skinner said is correct. If it detonates at a pressure value, it has nothing to do with the speed of the rocket.
Because no matter what speed it is flying, it will detonate when it reaches the same pressure when it finally hits the target armor, and this pressure value is the focus position, so the maximum penetration depth is reached.
Wang Xuexin actually knew this all along and didn't say it before just to prevent Skinny from returning to China.
