Chapter 791: Let’s Fight
After taking the photos, Gao Zhendong followed them to the sample gun warehouse. This kind of practical problem can only be solved by going to the site and taking a look at the equipment in person. If it is only solved by holding a meeting, the possibility is unlikely.
After listening to the introduction and report of the rocket launcher developers and reviewing all the existing design data and test records, we still have no idea about the source of this "ballistic intersection".
"From a system perspective, this thing should not have much to do with the design of the rocket." Gao Zhendong looked at the material and pondered.
"Chief Engineer Gao, why do you say that?" Chief Yue's subordinates have a strong desire for knowledge.
Gao Zhendong pointed to the test records and said, "If it is a problem with the rocket itself, then the probability of this problem occurring is much greater than what you recorded. Moreover, the installation of this missile is directional due to the existence of the spinning directional slider. This leads to a conclusion - if it is a problem with the rocket, then they should all deviate in one direction, or there is no pattern."
Due to the directional nature of the rocket installation, if the yaw is caused by the missile body design, it should deviate in one direction.
Of course, there is another possibility that the problem with the bullet is that it will cause random yaw, but it should not show this kind of regular directionality.
"Mr. Gao is right. As for the problem with the rockets, the performance pattern should not be as it is now." Mr. Yue agreed with Gao Zhendong's analysis.
Gao Zhendong pointed at the sample gun in front of him and said, "It just so happens that this phenomenon of left bullet going right and right bullet going left with a relatively high probability happens to indicate a possibility. This problem lies in the system. It is given by the system, and the bullet itself does not have any big problems."
His words made all the comrades present heave a sigh of relief. If it was because of the missile, then it would be troublesome to modify it. The main reason was that the missile was like a nutshell. Although the 270mm rocket looked thick and long, there were actually not many things that could be done with it. The interior was very compact. It could be said that any slight change might lead to changes in the entire missile design, making it very troublesome to modify.
In fact, what they didn't know was that Gao Zhendong's various technologies and suggestions in previous meetings had helped them avoid many major risks and greatly accelerated the development of this missile.
This is probably another version of "A good warrior is not necessarily famous for his achievements." With Gao Zhendong's guidance, the development of the 270mm rocket seemed to be very smooth. Instead, it lacked the tension of ups and downs, and there was no need to frequently put out fires or solve problems.
Because those problems had been quietly covered up by Gao Zhendong through technological improvements long before the research and development began, so they were completely unaware of it.
Although Gao Zhendong has not found the problem yet, he has roughly deduced a very bold but seemingly reasonable result through mathematical statistical analysis of the fault phenomenon and test results. It can be regarded as a conclusion similar to "a blessing in disguise", which makes them both admire and happy.
No one dares to expect that technical support experts can just sit down and stare and solve the problem. That is not scientific, nor is it the universal law of the development of things. It takes a long time to understand the situation. It is not that simple. Now that we can preliminarily eliminate the problem in one direction, it is already a pleasant surprise.
In addition to being delighted, they also admired Gao Zhendong very much. What is a technical expert? This is a technical expert. With limited information, he can roughly grasp the direction of the problem and find some problems with just this little bit of information.
It can be said that even if Gao Zhendong did not make any further achievements afterwards, the mere conclusion that "the problem was not with the missile" had already completed his mission this time.
Having said that, Gao Zhendong certainly wouldn't let this end so hastily. Since he's here, he hopes to find as many problems as possible, preferably solving them completely.
——Since you are here already.
"Chief Engineer Gao, it's getting late today. You rushed here and started working right away. Do you think we should just do this today? If we want to find the problem thoroughly, it is necessary to conduct a few test firings. That way, we can understand the problem thoroughly and it will be helpful to solve it. We can't conduct the test firings today. I think you should take a rest today. Tomorrow, we will arrange a round of test firings. You can come and see it for yourself?"
Mr. Yue is much older than Gao Zhendong, but he speaks very humbly. There is nothing else to say, just two words: I’m convinced!
This sentiment had already existed during previous rocket artillery conferences, when what we saw was Gao Zhendong's theoretical foundation. Now, after seeing Gao Zhendong's ability to solve practical problems, this sentiment has become even stronger.
Gao Zhendong nodded: "Well, I'll follow your arrangements."
Mr. Yue’s arrangement makes a lot of sense. What we can see now is almost the limit. If conditions permit, we still need to see the situation of the test launch.
So, the group had a simple but lively working meal arranged by the factory, and Gao Zhendong also took a rest.
Early the next morning, General Yue took Gao Zhendong and got on a car to the test site. The range of this thing is too large and it cannot be tested in the factory.
At the test site, two launch vehicles were already on standby. It was apparent that while Gao Zhendong was resting, the relevant comrades here did not rest, but instead made preparations for the test launch overnight.
The comrades waiting at the test site saw the leaders and experts arriving together and hurried over to report the situation.
"Report, test preparations have been completed, please give instructions."
"Let's demonstrate the various motion functions of the launch vehicle to Chief Engineer Gao first." said General Manager Yue.
The movement of the launch vehicle, the erection, recovery, and rotation of the launch box, etc., are transplanted from the 180mm rocket, but some modifications and enhancements have been made according to the 270mm caliber requirements. This is one of the few values of the 180mm rocket that can be used. While the launch vehicle was being demonstrated, General Yue introduced it.
"…This launcher is modified from the 180 launcher. The original cage-type directional frame is changed to a directional tube. In order to adapt to the increased structural weight, the support device is changed to two-side support. Under the premise that the diameter of the hydraulic cylinder does not change significantly, it can support and erect and recover the heavier and longer launch tube..."
Gao Zhendong nodded as he listened. The comrades working on the 270 fire were already trying their best to utilize the existing results. There was no other way. The span of this bomb was too large and there was only so much they could do.
It looks like this area is basically mature, at least for now.
After the demonstration was complete, seeing that Gao Zhendong had no objection, General Yue ordered: "Car No. 1 is loaded with ammunition and ready to fire."
Vehicle No. 1 adjusted the rocket launcher to the loading angle, and several soldiers loaded eight rockets into the directional tube one by one. Since we want to see a complete launch test, let's do a full launch.
After vehicle No. 1 was loaded and checked, General Yue gave the order: "Ready! Fire all the ammunition!"
To fire all the bullets means to fire all the bullets.
Gao Zhendong was in the shelter, observing the launch vehicle in front of him with a telescope with great interest.
Amid the rumbling sound, flashes of fire appeared on the launch site, and two rows of eight rockets were fired one after another at intervals of 0.5 seconds.
In order to keep the launch vehicle balanced as much as possible, the rockets were not fired in sequence from left to right or from top to bottom, but rather one shot to the left and one to the right, like plum blossoms and bamboos. It can be said that General Yue and his team used all the conventional means of maintaining accuracy and thought of everything they could think of.
Smoke was rising above the launch site, and nothing could be seen. In the formula of the rocket propellant, Gao Zhendong increased the amount of ingredients such as aluminum powder and AP in order to increase the specific impulse. The higher the specific impulse, the heavier the smoke, and for a moment nothing could be seen.
After all eight rockets were fired, General Yue pointed to the smoke in the air and said, "Look, Chief Engineer Gao, the trajectories of two of them have crossed."
Looking around, thanks to the obvious smoke from the rocket, there were indeed two smoke trails crossing in the sky. Although the smoke had begun to disperse, the phenomenon was still very obvious and could be seen at a glance.
Gao Zhendong's super sharp eyes came into play at this time. Just now, he seemed to have figured out something.
He turned to ask Mr. Yue: "Let's not talk about crossing first. Doesn't this kind of yaw basically never occur during single-engine tests?"
President Yue seemed to have remembered something: "Yes! Single shots have basically never appeared before, it is very rare. So when we were testing rockets in the early days, we didn't find this problem at all. President Gao, what did you find?"
He was so happy in his heart that someone could tell the test process of the rocket in a confident tone, and his guess was quite accurate. He didn't believe that Chief Engineer Gao didn't have any discoveries.
Gao Zhendong did not rush to draw conclusions, but said vaguely: "I have some ideas, but I need to continue to watch."
"Well, look! Just look!" Mr. Yue was extremely excited. There was a way.
"Do you have chalk?" Gao Zhendong asked.
"Yes! Yes! Yes!" A comrade nearby hurriedly went to get the chalk. Gao Zhendong took the chalk and said to General Yue: "Reload again."
General Yue hurriedly did as he was told, and after Gao Zhendong finished loading the ammunition, he walked to the launch vehicle with a piece of chalk, walked around the launch vehicle, and wrote and drew on it, not knowing what he was doing.
President Yue followed behind him and watched him draw on several parts of the launch vehicle, but he didn't understand what he was doing.
But he was not in a hurry. Since the other party had a clear goal and seemed confident, he just had to wait. The answer would be revealed sooner or later.
Gao Zhendong walked back and said to General Yue: "Fire again, but don't fire all the bullets, just one! The one on the far left, in the bottom row."
