Chapter 344: More than double the improvement!
Before they left, Gao Zhendong and Lin Lianwei made a dinner appointment. Although both of them were in Beijing, their workplaces were a bit far away. If Lin Lianwei didn't call him, Gao Zhendong would have trouble finding him. This time, he just walked into a trap.

A few days after this incident, someone from the Changjian Factory called.

"Boss Gao, the warhead and engine you asked us to make are all ready. Although the anti-tank missile is not yet complete and cannot be tested with a counterweight, your simple warhead and engine are all ready. Can you come over and watch the test?"

People at the Changjian Factory call him in a more uniform way, no matter if it's the chief designer of a model or the chief engineer of the third factory, they can all be called Chief. Unlike other names, there are Director Gao, General Manager Gao, Consultant Gao, Captain Gao, etc.

This kind of test must have been done at the Changjian Factory, where there is a special test site prepared for these flying bombers.

Gao Zhendong was very interested. He thought it was okay to go for it. Men, after all, had low resistance to these things.

Gao Zhendong threw the task of building the third branch factory to Yan Chengde, who was busy with all his work, and asked for leave from the factory. He sent Lou Xiaoe to her parents' home and went straight to Changjian Factory the next day.

The road was in a bad condition at that time, but Gao Zhendong was riding in the factory's GAZ-69. There were two other people with him, but the issue of weapons and equipment had nothing to do with them.

The Changjian Factory was not too far from the capital. Gao Zhendong had been trying to get there after driving a GAZ-69 for almost a day.

Mr. Luo and the director of Changjian Factory had been waiting for him in the factory. When they saw him arriving, they expressed their warm welcome. The group had a simple meal, and Gao Zhendong saw the results of this experiment.

A batch only has the warhead, and this part is used to experiment with static armor-piercing. As long as the warhead is needed, it can be fixed in front of the target plate and detonated according to the ideal explosion height during the test.

As for the other part, the engine, warhead, fuse, and tail are all assembled, and even the steel launch tube is ready. However, this launch tube is a transitional thing, so it is rather casual.

The firing assembly is from the first generation rocket launcher, so let's use it for now.

In fact, there were rocket launchers at that time, which were copied from the RPG-2.

However, its performance is average. The static armor penetration depth is 100mm/65 degrees, or 180mm. The mechanical fuze at the base of the shell is quite average. When dealing with armor with a large angle, the shells often ricochet and fly out.

Anyway, when we fought the Russians in 69, this thing was basically useless against their T-62. Although it couldn't destroy tanks, it was still powerful enough to fight against other Russian armored vehicles, destroying 19 vehicles of various types in one battle.

In short, with the development of tanks, the first generation of anti-tank rocket launchers are pretty good except that they cannot be used against tanks, have a range of only 150 meters, and take up space.

The problem is, this thing is called an "anti-tank" rocket launcher, and it would be a bit ridiculous if it can't be used against tanks.

Of course, this was still 1960, and the problem of not being able to fight against tanks was not very serious.

The Changjian Factory used the same propellant as the first-generation rocket launcher to charge the warhead of the rocket launcher made for Gao Zhendong, and there was nothing else available now.

Seeing Gao Zhendong's eyes shining as he looked at these bad-tempered treasures, the comrades from the Changjian Factory all smiled. The male comrades who came here usually looked like this at the beginning.

However, it was already late, so the experiment was not conducted until the next day.

The next morning, Gao Zhendong had breakfast early and ran to the test site to wait.

Mr. Luo also brought his people to make preparations for the experiment in a busy and orderly manner.

As time passed, before 9 o'clock, the warhead static armor-piercing test was ready.

Everyone entered the bunker, and with a command from General Luo, a roar was heard.

"boom"

When the smoke cleared, comrades from the Changjian Factory gathered around and began collecting data.

A comrade in charge of data collection ran back and reported some bad news.

"Boss Luo, this is bad. There is no data."

What? No data? Both Mr. Luo and Gao Zhendong were surprised. They didn't even find a pit? Impossible.

The experimenter's next sentence made a 180-degree turn: "The 300mm target plate we prepared was completely penetrated. I don't know the exact penetration depth."

"What?" This time, Mr. Luo was the only one who was shocked.

To be honest, he was not very optimistic about the warhead designed by Gao Zhendong. After all, General Gao was not in charge of warheads. The trial production of these warheads was a bit like accompanying the prince to study. It was probably that it was not a big deal, so he might as well just play with General Gao.

After all, when the project just started, the leaders of the Defense Work Committee told them privately that they must try their best to create good working conditions for Mr. Gao and ensure his health and mood.

Moreover, the caliber of this warhead is the same as that of the first-generation rocket launcher, which is 80mm. Compared with the 180mm static armor penetration depth of the first-generation rocket launcher, preparing a 300mm target plate is already very considerate. Even if you, Mr. Gao, are a genius, you can't increase it by 67% all at once, right?
However, the result was that General Gao's warhead had enough power to penetrate the 300mm steel target with one shot. He looked at Gao Zhendong very awkwardly, but found that the latter was cheerful and did not look unhappy at all.

He didn't know that at this time, Gao Zhendong's inner thoughts were "It's stable, it's stable, 300 will be broken directly, 400 is hopeful."

He knew that the explosives at that time could not be compared with the charge of the 89 tube. You know, that charge had won an award.

Moreover, we might not have the capability to process the charge liner at that time, and the dimensions that we measured based on the drawings would definitely be different from the original ones, so it was impossible to achieve a penetration of 630mm.

But in his opinion, a 6% discount should be fine, right? There must be a 380~400mm penetration, right?

But this is just his expectation. He doesn't know whether he can achieve this penetration.

He didn't even consider why the target plate was only 300mm thick, he just knew that 300 was not enough!
So he looked very happy and laughed: "Okay, okay!"

Seeing that Gao Zhendong didn't show any unhappy reaction, Mr. Luo felt relieved. He was careless, he was careless. He underestimated Mr. Gao's ability.

Thinking about the pitiful 80mm of the 180mm barrel produced by his own factory, Mr. Luo felt ashamed. It was a pity that he was in the combat department. What a crap thing they were making. Mr. Gao could just casually make one that was much better than the one produced by his own factory.

He quickly said to the test personnel: "Stack the two target plates! Continue the test!"

Although the effect of stacking two target plates is different from that of a whole one, there is nothing we can do at this time. Let's take a look at the situation first.

Gao Zhendong smiled and said, "No need to stack them up. Just lay the target board flat and use the original height and width as the thickness."

Fuck, look at my pig brain, it’s 300mm thick, I can still test it if I lay it flat!
Mr. Luo was so angry that he laughed at himself, and quickly said to the tester: "Yes, let's do it!"

After the test personnel went to prepare, Mr. Luo turned around and said, "Mr. Gao, I admire you so much. With the same caliber, you just did this and the power increased so much."

Gao Zhendong smiled and said, "It's not that exaggerated. My combat unit is still far from ideal."

Mr. Luo wanted to pick up the warhead next to him and hit him. What he said was too shameless. You are so shameless. I can't say whether your new warhead can penetrate it, but my old rocket launcher can't penetrate it anyway.

Gao Zhendong had no intention of hiding his technology. "Boss Luo, I've studied it. To increase the armor penetration depth, in addition to increasing the caliber, if other conditions remain unchanged, another way is to increase the length of the charge. So the length of my charge is longer than that of the old rocket launcher. You can simply think of it as having a larger charge."

Mr. Luo quickly wrote it down and said, "Okay, increase the charging length. I've learned it."

Gao Zhendong added: "But it is not good if the charge is too long. The limit is three times the charge caliber. Any longer is meaningless. Considering the size, volume, weight, etc., I used more than twice this time."

This is because of the rarefaction wave that is introduced, or intuitively, the charge is too long and the energy cannot reach the other end.

Then he pointed to the blueprint and said, "But there is a bigger reason, this medicine cap!"

Mr. Luo looked at the charge cap with some surprise. It looked similar to the old rocket launcher, with no difference.

Gao Zhendong pointed at the charge liner and said, "Pay attention here. This is a double-tapered variable-wall-thickness charge liner. Compared with the old barrel charge liner, it further increases the effective charge amount of the warhead and increases the generatrix length of the charge liner. These can improve the velocity gradient and increase the jet length and velocity."

Mr. Luo was stunned by Gao Zhendong's words. He spoke both theoretically and practically. Am I in charge of the combat department or are you?
But the fact is that the warhead of General Gao has a very strong penetration capability.

He looked at the diagram of the warhead with an intoxicated expression. Learn! Learn and apply it to anti-tank missiles! It's so beautiful. Let's not talk about what anti-tank missiles look like. Just based on this technology, it is worth all the previous efforts.

During this gap, the experimenters have re-ready and the experiment continues.

There was another roar and smoke. After a busy period, an experimenter came back dancing with a probe in his hand and his finger stuck in a certain position.

"Boss Gao! Boss Luo! 427! 427! 427 millimeters!"

"Fuck!" Mr. Luo couldn't help but swear.

From 180 to 420, a 133% increase! What does this mean? This means that in front of this warhead, all tanks are just shells!
"Try again! Try again! Be careful!" He immediately jumped up and urged his comrades who were conducting the experiment to continue, but he also reminded them about safety issues. After all, everyone was very excited at this time and must not cause any problems.

Another roar passed, and the experiment was repeated ten times.

“420！420！420mm击穿率90%，没击穿的那一发也有411！”
