Chapter 761: A good thing to bleed Citizen
The test results shattered the last trace of luck in the hearts of the test participants.
Of the three rounds, two fell off during flight and behaved exactly the same. The only difference was sooner or later. By the way, the fuse of the second round that fell off exploded.
The remaining shot flew normally and successfully hit the target.
However, this round is of no use. Judging from the situation of the other two rounds, the bullet drop is not an accidental failure, but is most likely a major problem in the design or a batch problem in manufacturing.
Otherwise the failure rate would not be so high and the failure behavior would not be so consistent.
Fortunately, the fuse of one of the missiles exploded, and it was far away from the dumb bomb. With a glimmer of hope, Lin Lianwei led several soldiers who participated in the test to pick up the wreckage.
In the shelter department, the comrades from the Guidance and Research Institute looked at the wreckage and were speechless.
What was picked up was an empty shell. The rocket engine part of the missile. As for the guidance and control section of the missile head, it had been blown away to an unknown location.
"It hasn't exploded so far. The fuze should be passivated. I'm going to remove the control section. I made the fuze, so I'm the best person to remove it." The comrade working on the warhead stood up and was about to walk out. .
The control section records some key process data. I hope there is no problem and it may be helpful.
"Let me go. How to dismantle the control section and what is most important to dismantle, you don't know as well as I do." The comrade in charge of flight control did not give in.
In his opinion, if a missile drops, it is most likely a flight control problem. This responsibility must be borne by oneself.
Just as the two were fighting for it, the person in charge of the model spoke.
"Don't grab it! Wait! Wait until the battery on the bomb runs out!" Although he is not a fuze maker, he knows very well that this bomb is equipped with a proximity fuze. The temper of this thing after the safety is released is not good at all. .
After saying that, he looked at everyone: "If anyone tries to grab it again, I will ask comrades in the army to destroy the missile with one shot!"
He turned to look at the comrade in charge of the overall structure: "How long is the continuous power supply time of the missile-borne battery?"
"Five minutes. In this weather, it may be shorter." Five minutes sounds short, but for a portable air defense missile, it is actually very long. This kind of missile goes from power-on to strike. It only takes tens of seconds to hit the target. 5 minutes is enough to complete the process of canceling - aiming again - shooting many times, and the deflation time of the cooling cylinder is actually only that long.
"Wait! Wait until tomorrow morning to dismantle it!"
The boss has left enough safety redundancy.
The seemingly outrageous comparison of time, 5 minutes and a day, but behind every seemingly outrageous rule, there is at least one bloody lesson, just like a squib in a mine, which cannot be dealt with in a short time according to regulations.
The next morning, the control section was finally dismantled, and the remaining warhead was destroyed by a single shot from the soldiers.
Fortunately, the data in the control segment can still be read.
Looking at that little bit of data, the comrade in charge of flight control analyzed it for a long time.
"The projectile is unstable and beyond the control range of the flight control system!"
Fortunately, the cause of the failure was found, and it doesn't seem to be a very troublesome problem.
Everyone breathed a sigh of relief and began to discuss solutions.
"It seems that the elastic wings are too small. How about increasing the folding area of the elastic wings?"
The stability of this projectile depends on the stability of the projectile wings.
The comrade in charge of overall and aerodynamics shook his head: "No, you think I don't want to make the wings bigger? It's really not possible! The diameter of the missile body is too small, and the wings that pop out will not be big."
"Increase the folding length?" Fold it a few more times, and the area will be larger after unfolding.
"It's difficult. The multi-fold elastic wings are not strong enough after unfolding. This problem is difficult to solve." This obvious solution has been considered by the comrades in charge of the overall situation for a long time.
"Increase the slot length of the ejection wing, and change the 90-degree folding to a translational ejection. In this case, a long elastic wing extending along the direction of the missile body can be formed, and the total area should be sufficient."
"This is even worse. This solution will cut the internal space of the missile body, and the contents inside cannot be arranged at all." The comrade in charge of the overall plan almost cried. This method is really killing me.
Everyone looked at each other, ah, this...
One comrade's eyes lit up: "How about we change the plan and change the wing stabilization to rotation stabilization?"
There are indeed rotationally stable anti-aircraft missiles, and the number is not small.
"Is the change in this plan too big?"
"It's not a big deal. I can't find a better way right now."
"Maybe, our anti-tank missiles are rotationally stable, right?" There is actually a problem with this statement. The rotation of the Chijian-61 is not mainly for stability. After all, the wings of that thing are already large enough, but to save a Pair of vector spouts.
"If the rotation is to be stable, the rotation angle of the missile must be collected, and a gyroscope must be added. This will increase the weight of the missile and increase the complexity and uncertainty of the system. Moreover, the diameter of the anti-tank missile is larger than ours It's too large, and the gyroscope it can deploy may not be able to be deployed here," the chief engineer raised an objection.
Comrades only need to consider solving the problem of stability. As the chief engineer, there are many things to consider. The portable anti-aircraft missile has a diameter of 70mm, and the anti-tank missile has a diameter of 120mm.
Seeing the deadlock, the commander suddenly remembered something. He could see more information in the system than other comrades.
He turned to look at Lin Lianwei: "Lian Wei, you, me, the comrade in charge of flight control, bring the data, and we will go to the capital on a business trip."
It's funny to say that the capital is where their unit is located, but now they are conducting experiments in Syracuse, and returning to the capital has become a business trip.
When Lin Lianwei heard this, the boss was trying to shake him down!
"Boss, this problem is too specific, and the solution is very limited. He may not be able to solve it, right?"
The boss smiled: "I don't know about that. Anyway, I only know that the comrades engaged in anti-shipping also lost their bombs not long ago, and they also went to the capital to solve the problem. And even if you want to stabilize the rotation, don't forget Chijian- Where did 61 come from?”
Lin Lianwei then remembered that the Chijian-61 was also built by Gao Zhendong. When it comes to the stability of the rotation of the missile, especially this small tactical missile, there is really no one else who is most suitable to consult.
In fact, what they don't know is that not only the small tactical missiles, but also the stability of the rockets are now being solved by Gao Zhendong.
"Okay, I'll call him first and ask him to stay." Lin Lianwei volunteered.
The latest chapter of this novel was first published on 6@9书#. Please go to Liujiu Book Bar to read it!
"Well, that's right. You call first. He's probably very busy and it's hard to make an appointment." The boss felt that Lin Lianwei's arrangement was really right. It's easy to get things done when you have acquaintances.
They returned to the office area of the Syracuse Test Center, and Lin Lianwei went straight to the confidential room.
Now it is much more convenient for Gao Zhendong to make and receive phone calls. The confidential line is directly connected to the office, mainly his phone. There are many more people who use the confidential channel than the ordinary channel. Otherwise, time will be wasted on the road.
After listening to Lin Lianwei's words, Gao Zhendong laughed, and he remembered something interesting.
"Hey, Lao Gao, don't laugh all the time. Tell me, when will you leave me some time?" Lin Lianwei was not polite.
Gao Zhendong smiled and said: "I don’t have to leave time for you..."
"What? You want to give up? You're not being kind. You reached out to Lao Su, but here you stand on the shore and watch?" Lin Lianwei became anxious.
"How is that possible? That's not what I meant."
For Gao Zhendong, within a certain period of time, Lin Lianwei's matter is even more important than Su Weihua's.
Because Lin Lianwei can bleed Citigroup, and he can bleed heavily!
What is the most famous thing about Citigroup in Cochin? It's nothing else, it's a helicopter!
This was the first time that Citigroup used helicopters in a large-scale war. It was easy to use, but the losses were also huge. More than 5,000 helicopters were lost due to various reasons.
But how many of them were shot down by portable anti-aircraft missiles? More than 200 aircraft.
It's just that little, but it's not enough. If the Citigroup guy next door sees it, he'll think he can't afford to fight. Go up again, one by one!
There are several reasons for this phenomenon. One is that the Sam-7 was born and entered the market relatively late. Secondly, the technical and tactical performance of the Sam-7 is also relatively poor, especially the anti-interference of the single-color single-band seeker. Performance is not good.
Gao Zhendong's requirements are not high, he hopes to turn 200 into 1,000.
In any case, compared with the unification of Cochin and the establishment of Citigroup's roots in the southern seas, the latter is undoubtedly more serious. The former is ringworm and scabies, while the latter is a serious problem.
Think about the consequences of having the Citizen's Seventh Fleet squatting in Jinlan Bay south of Cochin?
Therefore, Lin Lianwei's matter is very important. This is a good thing to bleed Citigroup.
"That's pretty much it. Then tell me the time." Lin Lianwei was very satisfied.
However, Gao Zhendong's words made him almost jump with joy.
"I mean, I can solve your problem right away." Gao Zhendong's voice sounded like the sound of nature to Lin Lianwei.
"Ah? Don't you see our design materials and test data?"
Gao Zhendong's voice sounded very confident on the phone: "No. In this way, I will draw a picture for you, and you will know it at a glance. The method is crude, but it is definitely easy to use. If you don't understand, you can give it to me again. Call, haha.”
Lin Lianwei hung up the phone in doubt. Twenty minutes later, a message popped up on the computer in the confidential room, telling him that he had received an encrypted email.
Lin Lianwei, the boss, and the comrades in charge of general management and flight control opened it and looked at each other.
The letter is very simple, just a compressed picture and a few sentences of introduction and explanation.
But the effect was very good. Several comrades looked at it for a long time, and finally the model manager said a few words.
"Absolute! It's amazing! The method is very crude, but it's absolutely amazing!"
