Chapter 791 Just take a look
After taking pictures, Gao Zhendong followed them to the sample gun warehouse. This kind of practical problem can only be solved by on-site inspection of the equipment. It is unlikely to be solved by just holding a meeting.
After listening to the introduction and report of the rocket launcher developers, and reviewing all existing design information and test records, we still have no clue as to the origin of this "ballistic cross".
"Systematically speaking, this thing shouldn't have much to do with the design of rockets." Gao Zhendong looked at the material and pondered.
"General Engineer Gao, why do you say that?" Mr. Yue's subordinates are very curious about knowledge.
Gao Zhendong pointed to the test record: "If it is a problem with the rocket itself, then the probability of this problem is much greater than what you recorded. And the installation of this projectile, due to the existence of the spin directional slider, has a direction. Sexually, this will lead to a conclusion-if it is a problem with rockets, then they should all be deflected in one direction, or there may be no pattern.”
Due to the directionality of rocket installation, if the yaw is caused by the design of the missile body, it should all deviate in one direction.
Of course, there is another possibility that the problem of the bomb is that it will cause random yaw, but it should not show this kind of regular directionality.
"Mr. Gao makes sense. As for the problem of rockets, the performance pattern should not be like this." Mr. Yue agreed very much with Gao Zhendong's analysis.
Gao Zhendong clicked on the sample cannon in front of him: "It just so happens that this phenomenon of left bullets going right and right bullets going left with a relatively high probability of occurrence just indicates a possibility. This problem is caused by the system and is given by the system. The bomb itself is not a big problem.”
His words made all the comrades here breathe a sigh of relief. If it was the bomb, it would be troublesome to change it. The main reason is that the bullet is made in a screw shell. Don't look at the 270mm rocket. It is thick and long, but in fact there are not many tricks that can be played. The interior is very compact. It can be said that any change may cause changes in the full-bomb design, which is 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 big mines and greatly accelerated the development of this bomb.
This is probably another version of "A good fighter has no great achievements." With Gao Zhendong's guidance, the development of the 270mm rocket seemed to be very smooth, but there was less ups and downs of tension, and there was no need to frequently put out fires. Or solve a problem.
Because those problems were quietly covered by Gao Zhendong with technical improvements long before development began, leaving them completely indifferent.
Although Gao Zhendong has not yet found the problem, he has roughly deduced a very bold but seemingly reasonable result through mathematical statistical analysis of fault phenomena and test results, and it is also a similar "unfortunate" result. "It's a blessing", which made them both admire and happy.
No one dares to expect technical support experts to sit down and just stare and solve the problem. That is unscientific and not the universal law of development of things. It takes a long time to grasp the situation, it's not that simple. It is an unexpected surprise to be able to preliminarily eliminate problems in one direction.
In addition to being happy, they also admired Gao Zhendong very much. What is a technical expert? This is a technical expert. With limited information, only this little thing can roughly grasp the direction of the problem. Find some problems.
It can be said that even if Gao Zhendong has no further achievements, just this conclusion that "the problem is not the bomb" has completed his mission this time.
Having said that, Gao Zhendong definitely can't end it hastily. Now that he is here, he hopes to find out all the problems as much as possible, and it is best to solve the problem completely.
——You have come.
"General Engineer Gao, it's late today. You got into work as soon as you arrived. Do you think we should do this for today? If we want to find the problem thoroughly, it is necessary for you to conduct a few rounds of test firing. That way A thorough understanding of the problem will also help solve the problem. We can’t fight today. I think you should rest today. We will arrange a test launch tomorrow. Can you take a look at it?”
Mr. Yue is much older than Gao Zhendong, but he is very humble when he speaks. There is nothing more than two words, "I am convinced!"
This sentiment has been felt as early as in previous rocket launcher meetings. What I saw at that time was Gao Zhendong's theoretical foundation. And now, after seeing Gao Zhendong's ability to solve practical problems, this emotion is even stronger.
Gao Zhendong nodded: "Well, I will listen to your arrangements."
Mr. Yue's arrangement makes sense. What can be seen now is almost the limit. If conditions permit, we still have to look at the test firing situation.
So the group of people had a simple but lively working meal arranged by the factory, and Gao Zhendong took a rest.
Early the next morning, Mr. Yue took Gao Zhendong on the car to the testing site. The range of this thing was too great and could not be tested in the factory.
At the test site, the two launch vehicles were already waiting. It could be seen that while Gao Zhendong was resting, the relevant comrades here did not rest, but prepared for the test launch overnight.
The comrades waiting at the test site saw leading experts arriving hand in hand, and quickly ran over to report the situation.
"Report, test preparations have been completed, please give instructions."
"First, show the various sports functions of the launch vehicle to Chief Engineer Gao," said Mr. Yue.
The movement of the launch vehicle, launch box erection, recovery, rotation and other functions are transplanted from the 180mm. Only some modifications and enhancements have been made according to the needs of the 270mm caliber. This is one of the few values that can be utilized by the 180mm. . The launch vehicle demonstrated while Mr. Yue introduced it.
"...This launcher was modified from the 180-fire. The original cage directional frame was changed to a directional tube. In order to adapt to the increased structural weight, the support device was changed to two-side supports. In the hydraulic Without significant changes in the diameter of the tube, it is possible to support, erect and recover heavier and longer launch tubes..."
Gao Zhendong listened and nodded. The comrades who were engaged in the 270 fire were already trying their best to make use of the original results. There was no way. The span of this bomb was really too big, and what they could do was also very limited.
It looks like this area is basically mature, at least for the time being.
After all the demonstrations were completed, seeing that Gao Zhendong had no objections, President Yue ordered: "Car No. 1 is loaded and ready to launch."
Vehicle No. 1 adjusted the rocket launcher to the loading angle, and several soldiers loaded the eight rockets into the directional tube one by one. Since we want to see the complete launch test, let's do a full launch.
After the No. 1 vehicle was loaded and checked, Mr. Yue gave the order: "Get ready! Fire all the bombs!"
To fire all the bullets is to shoot out all the bullets.
Gao Zhendong was in the shelter with great interest, using a telescope to observe the launch vehicle ahead.
Amidst the rumbling roar, the launch site flashed with fire, and two rows of eight rockets were fired one after another at an interval of 0.5 seconds.
Check out the 16-9 book bar to see the correct version!
In order to maintain the balance of the launch vehicle as much as possible, the rockets are not fired in sequence from left to right, top to bottom, but like bamboo among plum blossoms, one on the left and one on the right. It can be said that , Conventional accuracy maintenance methods, Mr. Yue and the others used all the methods they could, and thought of everything they could think of.
Smoke was rising from the launch site, and nothing could be seen. In the formula of the rocket propellant, Gao Zhendong increased the ingredients such as aluminum powder and AP in order to increase the specific impulse. The same smoke was also much larger. , nothing could be seen for a while.
After all eight rockets were discharged, Mr. Yue pointed to the smoke in the air: "Look, Mr. Gao, the trajectories of two of them have already crossed."
Looking around, thanks to the obvious smoke from the rockets, there are indeed two smoke trails intersecting in the sky. Although the smoke has begun to disperse, the phenomenon is still very obvious and can be seen at a glance.
Gao Zhendong's super strong eyes came into play at this time. Just now, he seemed to have seen something.
He turned around and asked Mr. Yue: "Let's not talk about crossovers. Is this kind of yaw basically not going to happen during single-engine tests?"
Mr. Yue seemed to have remembered something: "Yes! A single shot has basically never appeared. It is very rare. So when we conducted rocket test firings in the early days, we did not find this problem at all. Mr. Gao, what did you find?"
He was so happy that someone could tell the story of the rocket test firing in a confident tone, and his guesses were quite accurate. He didn't believe it if Chief Engineer Gao didn't discover anything.
Gao Zhendong did not rush to draw conclusions, but said speciously: "I have some ideas, but I still need to keep looking."
"Well, look! Just look!" Mr. Yue was extremely excited. There is a way.
"Do you have any chalk?" Gao Zhendong asked.
"Yes! Yes! Yes!" A comrade next to him quickly went to find the chalk. Gao Zhendong took the chalk and said to Mr. Yue: "Load the bomb again."
Mr. Yue quickly complied with the instructions, while Gao Zhendong himself, after loading the bomb, walked to the launch vehicle with a piece of chalk, walked around the launch vehicle, and wrote and drew on the launch vehicle, not knowing what he was doing. matter.
Mr. Yue followed him and watched him draw on several parts of the launch vehicle, but he didn't understand what he was doing.
But he is not in a hurry. Since his goal is clear and he seems confident, he can just wait. The answer to the mystery will be revealed sooner or later.
Gao Zhendong walked back and said to Mr. Yue: "Fire again, but don't fire all the bullets. Just shoot one! Just on the far left, the one in the row below."
