Su Wen showed Liu Ming a portion of the RPG information.
This information was compiled by Su Wen according to the relevant information he had comprehended in his mind.
According to these documents, RPGs were not only very simple and portable, but they could also be carried on the shoulder and hit wherever they pointed. They were very powerful. They could not only hit the Japanese tanks, but they could also take out the Japanese bunkers. Most importantly, with the current conditions of the Eighth Route Army, it was possible to create them.
This was also what excited Liu Ming.
If such a cannon was manufactured, it would greatly increase the Eighth Route Army's guerrilla warfare ability.
A divine artifact!
It was simply a divine artifact.
That was why Liu Ming was so excited. He felt that it was not enough to arrange for a company of guards to protect Su Wen.
Liu Ming looked at Su Wen excitedly and said,"Su Wen, can such an RPG cannon really be produced?"”
"You're really amazing. You just made the Flying Thunder Cannon, and now you've made this kind of shoulder-carried rocket launcher.”
Su Wen nodded and said,"According to my understanding of the Eighth Route Army's military industry, I think it's completely possible to create it."”
"After all, this kind of RPG cannon is relatively simple and cheap to make, but there are still some problems that need to be solved!”
The structure of the RPG rocket launcher was very simple. The barrel did not withstand the pressure of the chamber, so it was not difficult to design and process the materials.
The armor-piercing warhead was not difficult. The result of designing a semicircle cover was low efficiency, but it was more convenient to process the semicircle, and the thickness was more uniform.
The real technical difficulties of the rocket launcher were the fast-burning double-base propellants, the forming technology of the propellants, and the ignition/fire transfer design.
The fast-burning gunpowder was a special requirement of the rocket launcher. If the gunpowder could not burn completely before the rocket ejected from the barrel, the high-temperature gas would wash over the shooter's face and hurt him.
In order to meet this requirement, the double-base propellants of World War II could not be made with a nitrotoluene and nitrotoluene system. This system was too hard and was not suitable for casting. At the very least, nitrotoluene had to be added as a catalyst to reduce the oxygen balance.
Therefore, Su Wen's solution to the problem of the fast-burning gun powder was to use nitrotoluo-butanetriol trinitrate. In order to increase the shape and cohesiveness of the single-hole gun, he even used the original polysulfur rubber.
This was the difficulty.
According to Su Wen's current understanding of the situation, perhaps only Yingchan had such a chemical level and source of raw materials.
This was also the reason why Su Wen looked for Liu Ming.
He hoped that Liu Ming could mobilize the help of the overseas Chinese Americans.
Liu Ming looked at Su Wen and said,"Comrade Su Wen, if you have any questions, tell me. I will definitely solve them if I can!"”
"If we want to produce RPGs, we need to solve the problem of the fast burning speed of the gunpowder!”
Then, Su Wen roughly explained the problems related to the RPG's burning speed to Liu Ming.
The burning rate of the propellants was very important.
Since the burning rate could not be increased, the only way to increase the specific surface area was to increase the burning area by using more and thinner grains.
However, the negative effects of too many grains were that the ignition design was inconvenient, and the ignition time between the grains was not consistent. The unstable gas pressure in the engine combustion chamber caused the burning speed of the grains to be unstable, and the gas output and speed per unit time were poor.
If he could solve the problem of the burning speed of the gun powder, it would definitely be a good thing.
Liu Ming roughly understood the situation and nodded.""In other words, if we want to produce RPGs, we need to solve the problem of chemical equipment. Currently, only Yingchan can solve this problem?”
"That's right."
"Of course, there are also ways to settle for the next best thing. For example, if you can't solve the burning speed problem, you can increase the defensive shield to prevent the high-temperature gas from hurting the archer, and at the same time, increase the gunpowder and so on!”
Liu Ming looked at Su Wen and said,"Let's go, Su Wen. I'll bring you to see someone. Perhaps he can solve your problem."
