Chapter 191 The telemetry bomb finally flew the full range (3k)
Gao Zhendong came back from his teacher’s house and was in a good mood.
Firstly, it can help the teacher a little bit, and secondly, it is hoped to form his own information technology team.
The people at the computing center are very helpful, but sometimes it is not so convenient after all.
The people at the Third Rolling Mill are also very good, but they are not from information majors.
This had a certain impact on some of his ideas. At least, during the communication process with the computing institute, he no longer had to do everything personally.
Why does Zhuge Wuhou not know it? He still knows it. He can learn other things, but not this matter.
The next morning, the things from the computing center were delivered, which was the Modem circuit board Gao Zhendong gave them to make.
The components bought by the Lou family arrived earlier than this batch of circuit boards.
So Gao Zhendong became a welder with great interest, and he was interested in making electronic screws.
For him, it was considered a break.
——
Somewhere on the beach, a long command was given: "Four, three, two, unit, launch!"
The temporary trumpeter Su Weihua pressed the red button marked "launch" on the metal console, and the red light on the button lit up.
On the inclined launcher not far ahead, there is a spindle-shaped object with two triangular wings and a tail with a relatively large sweep angle. It is about six or seven meters long and slightly short and fat. There was a flash of fire behind it, and with a "rumbling" sound, it flew away from the launch pad, dragging a long line of thick smoke and flying into the distance.
"The booster is thrown away!"
"The main engine ignition is normal."
"The tracking of the No. 3 telemetry bomb is normal."
"The height of the telemetry bomb is normal."< br>
“The flight direction of the telemetry missile is normal.”
"Arrived at the predetermined range."
Not long after, an excited voice from the front came from the radio: "The telemetry bomb splashed down in the predetermined area, and the missile body is being salvaged."
The scene was full of joy, and from the missile The research institute has carried out cooperative improvement research on imitation anti-ship missiles. This is the first telemetry bomb using a radio altimeter and the third telemetry bomb in the entire imitation process.
Both the first two rounds were due to problems with the bellows barometric altimeter, resulting in altitude errors and test failures.
Because the altitude of the first shot was high and low, the telemetry bomb stalled during the rapid adjustment process and fell into the sea.
The other shot was more direct, and the altimeter directly brought the missile into the sea.
This time, Gao Zhendong came up with the idea and asked them to change the bellows barometric altimeter to a radio altimeter, and finally completed the journey successfully.
“Finally completed full-range flight.”
“After firing several rounds, we finally overcome the height problem.”
“Our bullets have a greater range than the original version. 5 kilometers away! ”
"Now there is the possibility of a beyond-visual-range strike, haha."
Don't get me wrong, the over-the-horizon strike here is actually only 40 kilometers. Strictly speaking, for people today, it is beyond the earth. The direct visual range caused by curvature is considered a beyond-visual-range strike.
For ordinary battleships, this distance is only about 20 to 30 kilometers.
The original range of this missile is 35 kilometers, and the fuel used is alcohol. So the joke about Lao Maozi's missile soldiers secretly drinking fuel is not necessarily false.
I took it from China and saw that it was not working. It was a waste of food, so I changed the fuel to kerosene. Since kerosene has a higher calorific value than alcohol, the theoretical range is just a little longer.
It’s hard to imagine what the designers in the north had in mind for using alcohol as fuel, because it doesn’t really have many benefits compared to kerosene.
If I have to say it, maybe the food production there is high and everyone likes to drink it?
However, after switching to kerosene fuel, this theoretical range was not fully realized. Since the imitation diaphragm barometer is not as good as the original barometer, the meteorological and temperature compensation measures of the original barometer have not been fully studied. Under such circumstances, none of the two early telemetry rounds could fly normally to the full range.
This time, the telemetry missile successfully flew the entire distance. Although there is still some data that cannot be confirmed until the missile body is salvaged and the data recorder inside is retrieved, the mere fact that it flew the entire distance is enough. It is a big step forward in solid work.
Su Weihua's superior engineer Qi Gong smiled and said: "Xiao Su, your classmate is the first to succeed this time, haha."
Su Weihua said with a smile: "Let's work together. Lian Wei and I also have contributions. Without us, he wouldn't have thought of this method in a short time, haha." Lin Lianwei is also here. This improvement project is a joint venture between the Institute of Guidance and Research and Su Weihua's unit. Cooperation, he happened to be designated to assist Su Weihua and the others in this area, so for the first improved telemetry bomb, relevant personnel from their Guidance Research Institute also came.
Lin Lianwei was also very surprised when he heard what Su Weihua said: "Yes, yes, yes, give him a few more meals, so that more problems can be solved, hahaha."
Qi Gong pointed at Su Weihua: "You two should treat me to a meal. Lian Wei, when you return to the capital, on behalf of our scientific research team, treat Director Gao to a meal. We can't show no expression at all. , Haha.”
Lin Lianwei shook his head: “No, no, several units in the capital just give him a technical consultant or expert certificate, it’s a paper shell, it doesn’t cost anything, hahaha.”
Therefore, it is not easy to learn well, but once you learn bad things, you will slip away. This is how everyone has gone through it.
Just talking and laughing, more than two hours later, the speedboat delivered the salvaged data recorder, and everyone immediately got into the intense reading and analysis work.
“The altitude control is very good and has been controlled within plus or minus XX meters of the target flight altitude.”
“The response speed is normal. After the telemetry missile changes the target altitude, the control system responds very quickly. Fast, the adjustment time meets the requirements.”
“After the telemetry missile entered cruise flight, there was no overshoot or lag in the entire altitude control.”
"It's done, this way works!"
"."
Gao Zhendong, who was working, received a phone call. On the other end of the phone was Lin Lianwei's excited voice: " Lao Gao, our experimental commander wants to talk to you!"
Before Gao Zhendong could react, the voice on the other end of the phone was replaced by a slightly calm middle-aged voice: "Director Gao, Hello, my name is Qi XX,."
". I can't reveal more about the specific situation, but I want to thank you. The principles and methods you provided have solved the problems that have been bothering us very well. This has taken our work a big step forward, Comrade Gao Zhendong, thank you!”
After Gao Zhendong listened, he probably guessed that the height problem of the anti-ship missile imitation was solved, and it was solved using the idea of the radio altimeter he provided.
Gao Zhendong was modest: "No thank you, no thank you, I'm just talking nonsense, we are still doing the specific work."
The other party smiled and said: "Director Gao is being humble. What we lack is the few words you said, haha. If this is all nonsense, then Director Gao will come to us and talk more nonsense when he has the opportunity, hahaha."
Gao Zhendong also laughed. Qi Gong said: "Haha, I will definitely come if I have the chance. If Qi Gong has time, please come to our place to have a look and communicate."
These words made Qi Gong's heart move, and he remembered the last time he got the On the day of radio altimeter principle and technology, Lin Lianwei talked about another thing.
Maybe, this Director Gao's place is really worth a visit.
Thinking of this, he was not polite: "Okay, okay, I will arrange work as soon as possible and come over to learn from Director Gao."
Missile, except for the rocket part , the rest of the whole body is automated, and now it seems that the other party is a top technical expert in automation. If you can go over and have a good exchange when you have time, maybe you can really gain something.
Gao Zhendong did not expect that the other party really meant this, which is also a good thing for Gao Zhendong: "If you don't take it seriously, you are welcome to come over and guide our work, haha, okay, okay, then I will Just stay in the capital and wait.”
——
When Gao Zhendong was obsessed with modem software debugging, Yu Yuncheng came over.
"Director Gao, we did some experiments and found that the thermal field was well controlled under vacuum conditions. After the protective argon gas was filled, the crystallization situation of the single crystal became worse. Is it caused by the argon gas? If it reacts, do we need to change to another protective atmosphere?”
Gao Zhendong thought for a while: “Is it possible that the crystallization condition will further deteriorate under flow conditions, and even polycrystalline conditions will occur?”
Yu Yuncheng looked surprised. Director Gao had guessed correctly. Since he could guess so accurately, there was a high probability that he knew what was going on.
“Yes, yes, it’s amazing, Director Gao, you guessed it right.”
Gao Zhendong smiled and said: "Actually, it's not my guess that's accurate. The main reason is that you have imagined this matter too complicated. The reason is very simple. To put it simply, the cold wind is blowing, haha."
Yu Yun Cheng didn't have the conditions to use a protective atmosphere before, so he had to use vacuum conditions to pull out four nines, so in his mind, this thing was relatively advanced and complex, and this subconsciousness somewhat affected his objective judgment of the facts.
He was a bit dumbfounded: "I have also thought about this possibility, but I think it is not that simple."
Gao Zhendong said: "It's very simple, vacuum environment, protective atmosphere, In the three environments of fluid protective atmosphere, the longitudinal temperature gradient rises step by step. The reason is actually caused by the cold air blowing. The heating part is supplied with heat source and is not affected by the flowing gas, but other parts are greatly affected. , To sum up, it will cause an increase in the longitudinal temperature gradient. When the longitudinal temperature gradient increases to a certain level, polycrystalline phenomenon will occur. "
This means that Yu Yuncheng is not familiar with the protective atmosphere. Change it. People like Beijing Steel Works who have engaged in argon-oxygen refining may have reacted immediately.
After receiving Gao Zhendong's answer, Yu Yuncheng was overjoyed: "It will be easier if you know the reason, haha, I will debug it right away."
After saying that, he ran to the DJS-59 computer room excitedly.
All the control systems are on the DJS-59. Gao Zhendong also lent him a person from the computing institute to cooperate with him in program debugging and computer operations.
