Chapter 792 The problem is solved, let’s talk about something else

With a “boom~~~whoosh~~~” sound, a rocket was fired.

As soon as the rocket flew out, Gao Zhendong jumped out of the shelter and ran towards the launch vehicle.

He carefully circled the launch vehicle again, then ran back and said to General Yue: “Fire another round! Hit the right side, the one in the bottom row!”

The clearer and more organized his requirements were, the happier General Manager Yue was, which meant one thing – perhaps in Chief Engineer Gao’s own opinion, he was getting closer and closer to the truth.

Even though Gao Zhendong didn’t say this now, let alone announce the answer, he was jumping in and out like this, and his tone was so excited and confident that if he said he hadn’t discovered it, none of the comrades present would believe it.

Mr. Yue was even more excited than him and fired another shot as requested.

The smoke had not yet dissipated when Gao Zhendong pounced over.

Soon, Gao Zhendong ran back and said to General Yue: “Fire three groups of full-bombs, but the interval between these three groups must be more than 3 seconds! Use the car you just used, don’t change cars!”

President Yue was secretly shocked. If these three groups were to be awarded, the money would be huge. But these three groups had to be awarded!
He turned around and gave orders, and his comrades quickly got to work.

The first group was hit, and Gao Zhendong’s face showed some joy.

The second group also played out. Gao Zhendong nodded and said, “Well, there is none either.”

After the third group finished, Gao Zhendong turned to Mr. Yue and said, “Mr. Yue, did you find anything?”

President Yue was even more excited than him: “There is no obvious cross-trajectory in these three groups!”

Although this may sound light, it is very good news for General Yue and his team. It is unprecedented that all three groups of bullets were fired without a single cross-trajectory.

Gao Zhendong nodded: “Right! That’s it.”

Other comrades were also whispering.

“Oh my god, there really is no more.”

“Just by changing the firing interval, the cross trajectory disappeared?”

“Yes, that’s right. According to the previous rules, it has never happened that three groups of full-round launches did not have intersecting trajectories.”

“But a 5-second interval between shots is too long. If you need a quick fire attack in actual combat, it won’t be effective.”

“Is there something wrong with your brain? Since Chief Engineer Gao can find a way to temporarily prevent the occurrence of cross-trajectory, it means that he has an idea about the cause. Maybe he can solve it in the next step.”

“Yes, yes, yes, look at my pig brain…”

President Yue looked at Gao Zhendong and said, “Chief Engineer Gao, what’s going on? Have you found the reason?”

Gao Zhendong laughed: “I guess I have found part of it. The problem lies in your bilateral supports.”

This statement silenced all the comrades. The purpose of double-sided support was to provide stability, but how could it become a problem?

Gao Zhendong waved his hand and said, “Come on, I’ll show you something.”

As he said this, he took the lead and walked towards the launch vehicle.

It seemed that it was time to go and see what he had just written and drawn. Sure enough, Gao Zhendong brought everyone to the place where he had been wandering around several times.

“Did you see the chalk mark?” Gao Zhendong pointed to the hydraulic support rod. There was a little white gray mark on it, which was exactly what he had just drawn.

“It seems… there are some signs of being pushed, and the magnitude of the pushing is quite large.” Mr. Yue observed carefully and replied.

The chalk marks on the hydraulic support rod are very obvious. It was pushed upwards for a long distance by the sleeve below, and the marks are very clear.

Gao Zhendong led everyone to the other side and asked, “Let’s see if the situation is similar to that over there.”

Everyone looked carefully and found that it was indeed the case.

Gao Zhendong pointed to the launch box above his head: “The problem lies here. In theory, rockets have no recoil, but in reality, there is still some, especially when the rocket leaves the directional tube, the flame gas sprays solidly to the tube mouth, which will definitely cause the launch tube to be pressed down as a whole. At this time, the downward force will be transmitted to the hydraulic strut, causing the strut to retract.” Then he pointed to the chalk mark on the hydraulic strut: “Due to various reasons, such as the manufacturing, design, and parameters of the hydraulic system, when the full bullet is launched quickly, the strut does not have time to reset, and the next bullet is launched. Think about it, what will happen?”

Everyone present was not a fool. After going over the situation described by Gao Zhendong in their minds, they immediately reacted.

“When firing from the left, the launch box as a whole sinks to the left, and the direction of the directional tube’s firing will deviate slightly to the left…”

“Yes, yes, yes. At this time, the right tube began to fire, but the right bullet was deviated to the left. After the right tube was completed, due to the same reason…”

“Then the launch box will sink to the right and deviate to the right overall. It is now the turn for the left bullet to be fired, and the left bullet will naturally deviate to the right when it is fired…”

You go left and I go right, we are both stubborn and never look back… Cross!
“Yes, yes, this forms a vicious cycle…”

“That’s amazing! This makes perfect sense! It makes perfect sense! I think that even if the reason Chief Engineer Gao mentioned is not the whole problem, it is at least the main reason!”

“Great, great, the problem has been found!”

All the comrades cheered. Another reason why they were so confident was that after Gao Zhendong asked to extend the launch interval to 5 seconds, the trajectory intersection disappeared. This strongly proved from the side that there is a direct connection between trajectory intersection and short launch interval.

Combined with Gao Zhendong’s analysis of the cause, which is directly related to the launch time interval, the root cause of all the problems will naturally become clear.

At this time, if anyone says that there is no connection between the two, his comrades will spit in his face and say nonsense, there is such an obvious connection here, are you blind?
Mr. Yue was also very excited. As expected, an expert can tell whether something is good or not with just one look.

“Mr. Gao, how do you think this problem should be solved?”

Gao Zhendong smiled: “What is the most stable graph?”

“The most stable…triangle!” Mr. Yue said without hesitation. This question belongs to the realm of elementary school. The triangular relationship between people is the most unstable one, but when it comes to geometry, it is different.

“By the way, your original support method, the four fulcrums of the two support rods formed a quadrilateral. The quadrilateral can be compressed and deformed, which is why it is inherently unstable. But the triangle is different. The relationship between its three sides is difficult to change. It is more inclined to move the entire figure together, rather than moving one side like a quadrilateral. In this way, at least the structural stability within the system is guaranteed, and its state recovery is much faster than that of a quadrilateral.” Gao Zhendong said.

Without Gao Zhendong’s reminder, General Yue suddenly realized: “Right, right, right, let’s make a very solid support directly in the middle of the box. In this way, the rigidity of the entire launch system is guaranteed. Even if this single hydraulic support rod cannot be restored in a short time, the left and right relative relationship of the launch box system is fixed, which makes it much easier to solve.”

Gao Zhendong nodded: “Well, that’s probably the reason. In short, if you want to shake, then shake the whole system together. Don’t shake here and there and stop, otherwise it will be difficult to solve the problem.”

President Yue grabbed Gao Zhendong’s hand and shook it vigorously: “Good! Good! Thank you so much, Chief Engineer Gao, you just solved our big problem by drawing a few chalk lines!” Although this problem looks simple, with the current technical environment and capabilities, the time spent on solving it will be calculated in years.

The comrades around him also applauded loudly. This was a true expert who came to solve their problems.

Gao Zhendong felt a little embarrassed. He actually didn’t have much experience in solving practical problems face to face, such as the time when he solved the diameter automatic control problem of a single crystal furnace.

But they were all acquaintances. It is rare to see a scene like today where strictly speaking all the people are strangers.

Seeing Gao Zhendong being surrounded by everyone who was thanking and congratulating him, the comrades who came with him straightened their chests, feeling that the task on their shoulders was heavier and more glorious.

Gao Zhendong looked at everyone and suddenly had an idea. He said to General Manager Yue, “General Manager Yue, this is all I can do for this problem right now. But I have some other ideas. Since we are here, why don’t we discuss them?”

He couldn’t think of these ideas during the first few meetings, before the actual design started, and it was a little early to talk about them then, but it is more appropriate now.

Hearing his words, General Yue and his comrades were extremely happy. This kind of opportunity doesn’t come often. They know how busy people like Chief Engineer Gao are. If they miss this opportunity, they will never have it again.

“That’s great, Mr. Gao, you say it and we’ll take note!” In the shelter of the shooting range, it was still a little cold at this time. The soldiers chopped up a few shell boxes and lit a fire. A group of people gathered around the fire, sipping hot tea on it and communicating with Gao Zhendong.

It was called an exchange, but in fact it was mainly Gao Zhendong who was speaking. Other comrades did not have as much experience in this area as Gao Zhendong. It was already very difficult for them to complete their current work, and they had not considered other issues so far into the future.

“First, I suggest that you don’t just focus on rocket launchers and rocket shells, but think bigger and longer-term, and consider the issue from a supporting and systemic perspective.” Gao Zhendong’s move was a king bomb.

“Supporting? System?” Mr. Yue seemed to be thinking about something.

“Yes, these two. When you study rocket launchers, don’t just limit yourself to a single gun fighting alone. You should start from the perspective of a combat unit and equip the rocket launcher with everything it needs! It is not necessary to equip it with all the equipment. This depends on whether our wallets are fat or not. But whether it is equipped or not is one thing, and whether it is thoughtful or not is another. You can use it, but you can’t live without it.”

The famous saying of the garbage man in his previous life was used again by Gao Zhendong.
