The hardware is right. It is not difficult to produce a rocket launcher. If it fails, you can just use a steel pipe. After all, rockets can fly when placed on the ground. The only problem is whether they will burn the shooter.
However, Su Xin still made some refinements to the rocket launcher: front grip, firing handle, small bipod and shoulder pad bracket, etc. She repeatedly adjusted the position and distance of these parts, and even made
The wooden model allowed Wang Xuexin to carry it and experience it in kneeling and lying positions.
Wang Xuexin was a little puzzled: "I said, it's almost enough, but it's so detailed?"
"You don't understand this, classmate Xiao Wang!" Su Xin replied with a proud face: "This is a battle. Soldiers often need to hold and aim for a long time on the battlefield. If the distance is wrong, it will increase the shooter's fatigue.
and discomfort, which in disguise increases the burden and affects combat effectiveness!”
When Wang Xuexin heard it, he felt that it was true, and that weapons and equipment should be handled with caution, otherwise it would be troublesome to modify them for mass production, so he followed suit.
"What do you call it?" Su Xin asked Wang Xuexin, who was taking aim in a lying position.
"What?" Wang Xuexin tilted his head.
"This gun?" Su Xin raised her head towards the rocket launcher and asked, "Have you not named it yet?"
"R...How can we name it?" Wang Xuexin chuckled: "Isn't this sorted out yet?"
Just now, Wang Xuexin almost blurted out "RPG"... Fortunately, he was clever and quick, otherwise the secret would have been exposed.
Su Xin thought for a while and said: "Otherwise, let's call it...shoulder-carrying cannon!"
"Shoulder..." Wang Xuexin was speechless for a moment: "I said, classmate Xiao Su, why are you so uncreative? A cannon carried on the shoulder is called a shoulder-mounted cannon? Just use a 'spray cannon' or a 'bazooka'
It’s okay if it’s not a ‘bazooka’!”
Su Xin's eyes lit up: "Bazooka! It's a good name. It fires like a rocket, and it also has a fire hose! That's why it's called a rocket launcher!"
I'm going to...
Wang Xuexin cursed in his heart, why is this girl thinking about blowing the fire torch all day long?
As for the propellant, Wang Xuexin left it to Asano Aihara and his gang to get it. But of course he wouldn't let them do it on their own. Researcher Asano Aihara has a high IQ, so if you give them too much freedom, they might do something evil.
Wang Xuexin asked Yao Guan to arrange for a dozen people to help.
They say they are helping, but they are actually learning skills. They work with the Japanese, and then clearly write down all their operations.
The fourth branch of the medicine jar factory even has an identical set... The technology should still be in your own hands. Don't worry. The devils are devils after all, and they are not my species. I always feel uneasy if the technology is in their hands!
At the same time, it is also very suitable for the solid gunpowder to be stored in the Fourth Branch Factory. The Fourth Branch Factory is originally responsible for the processing of gunpowder. The processing method of the solid gunpowder column has been improved by Wang Xuexin and omitted the most dangerous rolling process. There is no need to compare with other gunpowder production.
separated.
The medicine jar is very positive about this.
In his words: "I have been tinkering with black powder for decades, but it has been boring. Now I finally have a fresh one. I have to think about it carefully!"
As he spoke, he patted Xiao Dongbei on the shoulder and said: "Xiao Dongbei, if the Japanese come up with new gadgets in the future, you have to be more careful!"
Wang Xuexin responded repeatedly, but he thought to himself, there are only so many types of gunpowder, what else do you want that is new?
The real difficulty was the cannonball. Although Su Xin and the others made it look like a cannonball, there were several problems that they couldn't solve. They had no choice but to ask Wang Xuexin.
Su Xin actually wanted to compete with Wang Xuexin.
As a top student majoring in mechanical manufacturing and the director of Tangtang No. 3 Factory, others have already drawn the drawings, but can she still make it herself?
But some things are easy to think about but difficult to do, such as the problem of fixing rockets...
I thought that I just need to insert the rocket into the "blow torch" and the metal part is stuck in the firing handle.
But how do you get stuck here?
It's okay if you shoot from flat ground or from above, but what if you shoot from high ground against the enemy?
The entire rocket launcher is tilted downward, so the rocket launcher must not slide out of the "fire blaster"?
Su Xin thought of various ways, such as adding a card holder in the "blow torch", which would normally be stuck and release as soon as the trigger was pulled.
But what is helpless is that this way, the rocket has to be made with a slot, and it should not be just one, but a circle...otherwise it can only get stuck if it is aligned in the right direction.
And this will inevitably affect the rocket's flight attitude and even accuracy and range.
Not a good idea!
Especially if the card holder fails to release and the rocket fires again, there will be a big problem.
After much deliberation, I couldn't think of a good solution, so I had no choice but to come to Wang Xuexin with Hardware.
At this time, Wang Xuexin was working as a translator in the cave. Although the workers sent by Yaokan were diligent and eager to learn, they were unable to communicate with the Japanese.
There is no other way, Wang Xuexin can only come and stay busy for a few more days.
The difficulty in making propellant is that heptane is volatile and toxic. Inhaling too much steam will cause dizziness, nausea, anorexia and other symptoms. In severe cases, it will cause loss of consciousness and stupor... This thing is actually an anesthetic.
.
Therefore, the entire work process must be tightly wrapped in protective clothing made of waterproof ponchos, and then put on gas masks. Communication is through writing.
Fortunately, the Eighth Route Army still had a lot of gas masks. The reason was that the Japs often used poison gas bombs in China. If the Eighth Route Army got gas masks from the Japs, they would keep them.
That's why Wang Xuexin said that it would be dangerous for Asano and his team to do it by themselves. If they wear gas masks and get some poison gas out, they might stun the guards.
When Su Xin and others came to find Wang Xuexin, they could only wait outside.
Wang Xuexin came out at meal time. He carefully took off his protective clothing and mask, and then washed his hands with soapy water... Heptane will be absorbed by skin contact.
No wonder no one would think of using it.
Then Su Xin and others came up to talk about questions.
Wang Xuexin took the towel from the guard and wiped his hands while answering: "Have you ever thought about another question? If this rocket does not have a tail fin, it will not be able to maintain its flight attitude and will roll in the air?"
Su Xin said "Ah?" "Tail fin? How can it be put into the blowtorch?"
Wang Xuexin was used to Su Xin referring to the rocket launcher as a fire hose.
He handed the towel back to the guard and answered easily: "Simple! Use thin elastic steel sheets to make the tail fin. Usually, it is covered with a tail hoop. When the blowtorch is inserted, the tail hoop will automatically fall off due to friction, and the elasticity of the tail will support it.
If it is attached to the wall of the barrel, the rocket will not fall off after being hit. Aren't the two problems solved at the same time?"
Su Xin looked at Wang Xuexin in surprise for a long time but couldn't react!
It is indeed simple, but it is not simple at all when you think about it!
