Chapter 1335 A good news and a bad news
Just when Lin Chenggang's brain was running rapidly and he wanted to say something to save the situation, a voice from outside the car door saved the atmosphere that was almost unstoppable.
"Mr. Liu, Researcher Lin, some new results have been made on the data analysis team!"
The voice was a little unfamiliar to Lin Chenggang. It was definitely not the three cars I picked up just now. the person.
Liu Xiyun, who was sitting in the middle, turned around in surprise:
"So fast?"
According to experience, this kind of work that requires dismantling the projectile and analyzing the test results throughout the process usually takes at least 5-7 days to complete.
And this time, it took about fifty minutes...
"Well... the situation is a bit special."
The person who came to hold the tailgate of the car and stood Explained outside:
"I'm not a missile professional, so you'll have to go and take a look..."
The interior space of the command vehicle is quite cramped, with several crew members lined up in a row in a longitudinal direction. If you don't consider the top that requires pull-ups to pass through. For the cabin door, you must leave the cabin from the outside to the inside in sequence.
Lin Chenggang and Liu Xiyun took a lot of effort before they stood back under the scorching sun near noon.
The latter took the initiative to introduce the person who had been talking outside just now:
"This is Yu Zhefeng, an engineer from Electric Technology Group. He was originally responsible for the radar equipment of the missile and gun system. …”
Originally, this kind of indirect work connection is to recognize a familiar face, but the word "original" mentioned by the other party still made Lin Chenggang a little curious.
But the situation on the missile side is obviously more urgent, so I didn't ask specifically.
However, Yu Zhefeng took the initiative to take over the conversation: "Now I've done some tricks, I'll take care of everything..."
Lin Chenggang nodded with clarity.
This situation is not rare in the development process of model.
If the research and development of a certain subsystem is particularly smooth and the progress is significantly faster than the overall situation, then relevant personnel will often do some auxiliary work within their ability.
But Liu Xiyun explained from the side:
"In fact, Yu Gong is currently focusing on the research and development and cooperation of various radar equipment of the General Army's air defense system..."
" …”
Lin Chenggang was speechless for a moment.
Damn it, this time someone pretended to be.jpg
While greetings with each other, they also quickly arrived at an area surrounded by sandbags and earthen walls hundreds of meters away.
Because the cost restrictions and the relatively harsh working environment of the army's firepower weapons are not rare to explode or even ignite. Therefore, the Qingtongxia shooting range has specially set up such an area to deal with similar situations.
Of course, to today, the CT series propellant is an insensitivity fuel and is relatively stable in an unignited state. The CTK series requires special electrodes to provide voltage to ignite, so it is very safe.
When the three of them walked into the detection area, the unexploded bomb had been dismantled from eight pieces and placed on several tables according to different subsystems.
On the first glance, Lin Chenggang saw the largest propulsion section among them -
The solid rocket engine is a relatively integral structure, and it is difficult to be split into the state before production as it is. .
In addition, there are already a dozen technicians with different dresses around.
He walked forward quickly and briefly stated his identity.
The other party did not lay too much preparation, but directly turned the cylindrical power section to make the circular cross-sectional face to Lin Chenggang.
The other party didn't need to say much, and the latter had already seen the problem. "Is the medicine column cracked?" Lin Chenggang never expected that the final interruption of the combustion was such a relatively simple reason.
There is really no need to do other analysis.
This is the most direct reason. "Yes." The leading technical officer wearing the rank of colonel replied: "It's not obvious that we just used a probe to observe in-depth He said as he pulled a laptop from the side, which was a photo of some overexposed due to uneven lighting.
But after closer inspection, you can still recognize that this is an expanded image inside a circular medicine column.
In the central part, there are three dark shadows that run across the entire image.
In other words, the entire medicine column is divided into four sections like a knife-cut baguette.
That can only be said that it would be unreasonable if the engine is not turned off.
"But it makes no sense..."
Looking at the hideous and terrifying appearance in front of him, Lin Chenggang's face was full of doubt.
The matrix of CTK-2 propellant is to add electrically sensitive hydroxylamine nitrate and metal tungsten powder on the basis of CT-1. In order to avoid the strength risks of this very special combination, he also specially added three-dimensional Porous polyvinyl alcohol is used as a binder and has been tested several times before formally loading.
In theory, there should not be any physical fracture.
And, whether it is combustion pressure or external overload, the test of 0 target distance .8km is not the highest. Even if there is a problem, it seems that it should not be here.
So the root cause is probably the secondary power-up I discovered just now.
No mistakes, one song, one content, one in 6, one book, one bar, one reading!
But what is the connection between the two? I am still in the dark for now.
Although he is engaged in solid rocket power, he is not a major in chemistry, and it is feasible to be responsible for engineering research and development, but he is a little helpless in the deeper part.
After a while of silence, he put down the laptop in his hand and turned to look at Liu Xiyun who was following him: "There should be a bullet preparation?"
The latter nodded:
"There are 8 more rounds."
"Can you conduct a set of repeated tests in the afternoon?"
Liu Xiyun thought for a moment:
"The afternoon arrangement is to test the Haihongqi 10. If it goes well, there should be time after supper..."
...
What everyone did not expect was that although the fault was recurred in the second round of tests that night, there was a problem when attacking a target 15km away.
A missile failed to ignite the secondary ignition when it flew to the end normally, suddenly lost power, and eventually passed by the target.
Faced with this result, Lin Chenggang seemed a little confused.
On the one hand, this shows that his speculation about the root cause of the problem is correct, that is, during the secondary power-up process, some factors caused cracks in the propellant column, and eventually stopped working abnormally.
But on the other hand, it also shows that the occurrence of this fault is quite random.
Although the 5/6 hit rate on the surface is not unacceptable, a technical hidden danger that has not even been understood in principle cannot be ignored like this -
If I go back, it is not in the second place. The second ignition is, but a problem occurs during the first ignition, so the missile that was launched by the cold-launched ejector will directly hit the launch vehicle.
No matter how insensitive the propellant and the warhead are, it is impossible to be safe in this case.
Fortunately, this has not happened to the more traditional CT-1 propellant. Since testing started last week, a total of 39 missiles of all types have hit, which has made Lin Chenggang feel somewhat relieved.
"Forget it..."
Looking at the characteristic data in the control system that was almost the same as the time in the daytime, he sighed helplessly:
"It involves CTK-2 propellant All tests are suspended. I will go back to the capital first and try to find out the problem as soon as possible..."
Faced with this clueless situation, Lin Chenggang had to choose to give up the mystery and put himself in a report The idea of electronically controlled solid propellants and the situations encountered during the test were submitted to the management team of the hypersonic weapon project, hoping to obtain some support.
Then…
"Comrade Lin Chenggang, I have good news and bad news here." In the office, Chang Haonan said to Lin Chenggang with a complicated expression.
Then, without waiting for the other party to make a choice, they continued directly:
"The good news is that the problem you encountered is that there are probably some ideas on the Torch Laboratory. It is very likely that the Torch Laboratory has some ideas. It is because there is a problem with the electrical sensitivity of a certain component in the propellant, and a specific conclusion should be given in a relatively short time. "
The latter looked happy, but immediately remembered that there was another bad news:
"Then..."
"The bad news is that because of the change in the development plan, our aspirated hypersonic weapon... may no longer require a particularly powerful rocket booster."< br>
