A wire is connected to the launch port of the rocket launcher, a wire is also connected to the target, and these two wires are connected to an instrument.
Wang Xuexin guessed that this instrument could accurately sense the time when the rocket was launched and the time when the target was hit through wires, so the flight duration of the rocket was obtained.
Once you know the flight duration, divide the flight distance by the flight time to get the accurate flight speed.
With a "chirp" sound, when the rocket hit the target, the subordinate in charge of the instrument reported the speed: "Captain, 110 meters per second!"
Wang Xuexin thought it was a bit funny, but he folded his hands and said nothing.
Skinner looked at Wang Xuexin in confusion and asked: "Did we do something wrong?"
"No, you didn't do anything wrong!" Wang Xuexin replied: "It should be said that we did something wrong."
"What do you mean?" Skinner asked doubtfully.
"Our rockets are handmade, Captain!" Wang Xuexin replied: "The charge, weight and even shape of each warhead are different, so..."
Then Skinny understood.
If there is no standard for warhead weight, etc., it means that one hundred warheads will have one hundred speeds, so measuring speed does not make much sense.
Skinner weighed the rocket launcher in his hand and said, "I don't understand how you made this thing under such conditions!"
Skinner always thought that it was hard enough that he could only spend his spare time and even invest his own savings to develop rocket launchers without the support of the military. He never expected that there would be someone who would have a harder and much harder time than him.
But they were able to make better and more perfect rocket launchers under such difficult conditions.
"Can I see your rocket launcher?" Wang Xuexin raised his head towards the several ammunition boxes they brought.
"Of course!" Skinner was a little nervous, like a student whose homework was checked by the teacher.
Skinner opened the wooden box, took out a rocket launcher and handed it to Wang Xuexin. He said with a slight embarrassment: "It still has a lot to improve, we need some time!"
When Wang Xuexin took a look, he saw that it was indeed an iron pipe, with only two handles one in front of the other and a trigger. It was much simpler than the rocket launcher used by the Eighth Route Army.
However, the rockets are better than those of the Eighth Route Army. They are well-proportioned in shape, have a large caliber, and have more charges.
Wang Xuexin didn't say much. He fired a test shot with the help of Skinny. The range was almost the same, also more than fifty meters. The difference was that an irregular hole was blasted out on the steel plate, and the trees behind it were burned by the high temperature.
A piece of the metal was burnt after being ejected by the jet, and black smoke was still emitting for a long time.
Skinner explained: "This is hollow charge technology, which can penetrate a hundred millimeters of steel plate!"
Wang Xuexin said nothing. He was considering whether he needed this hollow charge technology.
It is true that the Eighth Route Army may not need to worry about the armor-piercing thickness of rocket launchers at present, because the Japanese mostly use light tanks with thin armor in China.
The question is... will the Japanese continue to use these thinly armored light tanks without making any progress?
Wang Xuexin thinks this is unlikely.
The reason is that the war between the enemy and ourselves is like a battle between spears and shields.
The reason why the Japs in history used light tanks on a large scale in China without improving them was because the Chinese army basically had no anti-tank equipment. Their thin-skinned tanks were already invincible in China and there was no need to change them.
but……
Now because of the emergence of Wang Xuexin, the Eighth Route Army, Shanxi-Sui Army and even the stubborn army have been equipped with anti-tank rocket launchers. How can the Japanese send tanks and armor to the front line even though they know that they cannot withstand enemy attacks?
The Japs are not fools. They will also change according to changes in the situation. It is impossible for them to continue to go to the battlefield with such a shield knowing that the enemy's spear can pierce their own shield.
In particular, the Eighth Route Army's rockets at this time could only barely penetrate the armor of the Japanese tanks. They only needed to increase the armor thickness by a few millimeters to be able to withstand the rocket launchers well.
Just like they used to put sandbags on the outside of the tank and weld a circle of shell casings.
This is what people say: "The higher the Tao is, the higher the demon is." The progress of the Chinese army will force the progress of the Japanese.
Therefore, Wang Xuexin believes that he must be forward-looking and cannot take it for granted that the Japanese have nothing to do. After all, the Japanese industrial capabilities are much stronger than that of China at this time, so their ability to make changes according to battlefield needs is also much stronger.
.
Otherwise, it will be the Chinese army that will suffer losses on the battlefield in the future.
Thinking of this, Wang Xuexin said: "Captain, I hope to get this technology. In exchange, I will help you improve the rocket launcher. What do you think?"
Skinner was stunned for a moment.
Improving the rocket launcher was exactly what Skinner wanted and the purpose of his trip, but he still felt that Wang Xuexin was talking too much.
The hollow charge technology was a patent they bought from a Swiss engineer for hundreds of thousands of dollars, and to improve the rocket launcher... Skinner didn't think Wang Xuexin could see the shortcomings and improve them so quickly.
Therefore, Skinny did not answer directly, but asked: "For example, what aspects do you think need improvement?"
What Skinner didn't know was that it was too easy for Wang Xuexin... As a modern man and a retired soldier who is very interested in weapons, Wang Xuexin knew the development process of the bazooka rocket launcher, and of course
Know what its shortcomings are.
If it doesn't work, Wang Xuexin will buy a finished set of modern bazooka rocket launchers. If anything is different, it will need to be modified. It will definitely not be wrong.
So Wang Xuexin took a rocket and raised the warhead, saying: "For example, the warhead you use is too sharp. This kind of sharp warhead may not have any problems when it is fired at a high angle of attack, but it will be very serious when it is fired at a low angle of attack.
It is easy to be affected by airflow and deviate from the target, which is not a small problem on the battlefield!"
Skinny couldn't help being shocked when he heard this, because it had indeed experienced this situation in experiments, and experiments at low angles always failed to hit the target.
Before, Skinner thought it was accidental factors, such as wind changes, shooter aiming problems, etc. But now that Wang Xuexin said this, he realized that it might be a warhead problem.
What surprised Skinner even more was...Wang Xuexin could come to a conclusion just by looking at the shape of the warhead.
However, Skinny quickly gave a corresponding explanation on his own. They must have encountered similar problems in actual combat, so they knew this.
Then Skinner secretly rejoiced that this trip was indeed not in vain. These experiences cannot be obtained in a laboratory.
"How is it, Captain?" Wang Xuexin asked: "You give us the technology and we give you the experience. This is fair and is the goal of our cooperation. Do you think so?"
Skinner nodded and said: "But this is not something I can decide. I need to ask my superiors for instructions!"
"Of course!" Wang Xuexin replied.
However, Wang Xuexin believes that this will not be a problem, because it will not harm the eagle sauce.
