Chapter 547 U-2 Seminar
Just when everyone was at a loss for this thin wire, there was a knock on the office door.
The person in charge of the guidance system went to open the door and was the model chief engineer of the heavy anti-tank bomb.
He had a strange look on his face, and he could tell he was excited at first glance, but there was something else in his excitement.
"Mr. Zhang, why are you here?" The person in charge of the guidance system was a little curious and ashamed. He was not going well here. It obviously affected the overall progress of the model. The boss came here. .
As the chief model engineer, Mr. Zhang himself is also very busy. What stopped the re-bombing research team was not just a problem with the wires, but many problems.
However, Mr. Zhang's reaction was a bit beyond his expectation. He smiled quite happily: "Old Zhou, your problem is solved!"
Is it solved? Could it be that Mr. Zhang did it himself? That’s not right either. Mr. Zhang’s skills are nothing to say, but his professional direction is obviously not in this direction.
"Mr. Zhang, what do you mean?"
Mr. Zhang picked up a printout of the decrypted email in his hand: "The National Defense Work Committee just sent it today, targeting you. Solutions to the problem of broken wires ”
Um? Is this a good thing? Under normal circumstances, the National Defense Work Committee would not interfere with these specific tasks, but now they can't help but take action. It seems that they can't stand it anymore.
Gong Zhou immediately grabbed the piece of paper from Mr. Zhang’s hand and read it carefully.
The plan on the paper can be summed up very simply, with just three words: "Add silk!"
These three words were both a sudden realization and a bolt from the blue for Zhou Gong.
Looking at the mechanics, mechanical properties, and electrical parameters of the wire given on the paper, it’s as if this bomb was customized for myself.
As a Chinese, how could we forget this treasure passed down from our ancestors? Light weight and high-strength raw materials are easy to obtain. Although they are not cheap, there is no doubt that they are not expensive compared with exotic materials.
It’s so shameful that I keep my eyes on those advanced materials and processes every day, but I didn’t expect that one of the oldest textiles can solve the most troublesome problems.
As for the actual efficacy, there was a sentence on the paper that made Zhou Gong secretly frightened.
“This type of reinforced conductor has been tested and is unbreakable at a missile flight speed of 230m/s.”
There are two things that scare me. One is that I don’t know about the defense work. Where did I find this technology? The flying speed is a little faster than my own, but the test has been completed.
Second, there are other equipment that also use this kind of wire, and the conditions and methods of use are similar to your own ammunition.
"Mr. Zhang, where did this come from?"
"The National Defense Work Committee didn't say anything. It just said that after receiving our report, it asked for the technology from a brother unit. By the way, The National Defense Work Committee said that they were worried that we would not have enough time to make the wires ourselves, so they also helped us get a batch of wires for us to use first.”
The National Defense Work Committee was also very considerate. It's just that this thing is too coincidental.
Few types of equipment can use this kind of wire.
"Mr. Zhang, is there another unit doing the same bomb?" Zhou Gong's head turned quickly.
"I didn't say anything, so don't ask around. Regardless of whether it's true or not, it's rare for someone to be willing to help."
Yeah, I almost made a mistake! Zhou Gong put away his thoughts and quickly arranged for someone to go to the capital to pick up the things. The National Defense Work Committee must get the goods back. Even if he knows this idea, there must be a process from the idea to qualified wires. , a lot of time will be wasted.
If you don’t use the ready-made ones, there is something wrong with your head. This is not the time to be concerned about face.
A week later, Mr. Zhang, Zhou Gong and other people watched a test bomb flying out with flames. After flying for more than ten seconds, it plunged into a large bomb that had been prepared long ago. In the mound.
A group of people used the most primitive method, starting from the wire end of the manual control box and walking all the way, following the wires that fell on the ground towards the impact point.
The further they walked, the better they felt. Thin wires were faintly discernible on the land in early spring. Although it was a bit difficult to find them, what made them happy was that they were not broken!
Waiting for them to follow the wires all the way to the big mound, they felt excited as they watched the wires piercing into the mound as the missile body.
"Mr. Zhang, it's done! It works!" Zhou Gong was happier than anyone else. Seeing that the first obstacle to the guidance system was eliminated, as the person in charge of the guidance system, one can imagine his mood.
"Well, you still have a lot to do next! You can't waste time." They have all realized that there must be a kind of equipment that does similar things to them, maybe For them, time is a matter of life and death.
When Zhou Gong thought that he had only solved the problem of whether he could control it, as for whether the shot was accurate, there were still countless problems waiting for him, he couldn't help but fall down again.
Fortunately, if you are imitating it, it will definitely be faster than starting from scratch. Now there are anti-tank missiles that can be imitated in China. This is the only one that has no semicolon. No matter how powerful others are, their progress will definitely not be as fast as mine. This put them all at ease a little.
After solving one problem, you have to start from scratch to solve other problems. As the saying goes, the road is like iron, and now we can cross it from scratch.
The comrades in the replay research group could not help but ignited fighting spirit in their hearts.
Only this time, things might be much more serious than they thought.
——
Somewhere in the suburbs of Beijing, Mr. Xiao, who has been staying in the capital to work, finally got the situation of his comprehensive attack -5 and Gao Zhendong's various suggestions, and remade it The G-5 combat type wind tunnel test data.
During this period, he could be said to have risked his life with the comrades who came to Beijing with him. With the help of the comrades in the machine processing workshop of the No. 3 Factory, he made a wing with integrated side strips. , an aircraft model with simple wing-body fusion and serrated wing leading edges.
And through my old classmate working in a transsonic wind tunnel, I blew the wind at the fastest speed.
When his old classmate gave him the data, he smiled and said: "Old Xiao, what's wrong with you? This model doesn't look much different from the aircraft you built before, but this data is much better." Ah.”
Mr. Xiao took the data sheet and read it quickly.
Since he didn’t have much experience and the original attack-5 area law matching was good, Mr. Xiao followed Gao Zhendong’s suggestion and did not choose a side strip that was too large to minimize its negative effects.
But in this case, the aircraft's transonic shock wave resistance has further decreased, the high angle of attack lift has also increased significantly, and the aircraft's instantaneous performance has been significantly improved.
The emergence of wing-body fusion has further reduced the difficulty of area law matching. At the same time, the smooth body has indeed shown a decrease in drag and an increase in the lift-to-drag ratio in wind tunnel tests, although the design is relatively conservative. , it doesn’t look particularly significant, but if it is optimized, it is optimized.
And this part of the optimization, combined with the increase in internal space, there is no doubt that this thing can be done!
As for the leading edge serrations, Mr. Xiao can say that the wing knife can be reduced or even eliminated!
Although it is just a model that is not very accurate and does not have a very in-depth design, the potential it has shown makes Mr. Xiao very satisfied. With this change that is not too troublesome, the aircraft can basically be changed. The performance has been improved a little bit, and if we really go into detailed design, it may be even better.
Don’t underestimate this “little bit”. A little bit here and a little bit there adds up to a lot.
With the data in hand, Mr. Xiao thanked his old classmates and ran to the guest house of the Defense Working Committee with the data. He wanted to go back quickly and combine the changes in these data into the attack-5 combat type. into the performance estimation.
Fortunately, with the advent of confidential email, Mr. Xiao has been able to enjoy the benefits of "working from home" and "collaborating in remote locations" decades in advance.
The people who can provide him with support are not just the few people he brought to the capital, but the designers of the entire porcelain flying factory. Otherwise, even if there are people from the third rolling mill and the third rolling mill to help, he will not be able to support him. It's impossible to come up with new models so quickly.
He had to prepare things for Gao Zhendong before Gao Zhendong's meeting. He had little to do with Zhan-6. He couldn't attend the seminar and could only provide ammunition.
——
Everyone was busy, and time was also running out on Gao Zhendong’s side. Soon, he received a notice of the seminar on combat experience in shooting down the U-2.
Before receiving this notice, he had already made a lot of preparations, including Mr. Xiao from the Porcelain Flying Factory.
Sitting in the venue, people around me were speaking one after another.
In fact, it is relatively clear that the Z-6 fights the U-2. It is not a completely reliable method of warfare. When the enemy aircraft reaches the practical ceiling of 24,000 meters, it becomes quite difficult. It just depends on luck. The altitude difference has almost reached the limit of the Thunderbolt-1 infrared air-to-air bomb's combat slant range, but the drive away can still be achieved.
When U-2 reaches the maximum ceiling of more than 27,000 meters, it is basically out of reach. But the good news is that U-2 can’t do anything at this ceiling, and it will last for a long time. Maintaining this altitude is difficult.
The conclusion of fighting the U-2 is relatively clear. This jump tactic is a tactic that can effectively attack or inhibit the U-2 activity space under the condition that the current fighter ceiling is insufficient. It is recommended that the Air Force assume the relevant Troops preparing for combat missions generally carry out training in this type of tactics.
Moreover, unlike what Gao Zhendong originally knew, the Zhan-6's jumping strategy to fight the Citigroup Firebee drone is different. Now this method of launching missiles is not so dangerous against the Zhan-6 itself.
Originally, the Zhan-6 was fired with the cannon at the highest point of the jump. The recoil of the cannon would cause the height of the original fall to become more severe and uncontrollable.
But launching a missile is much better. There is not so much recoil. The missile flies out under its own power. What plays the role of momentum balance is not the aircraft itself slowing down, but the missile engine being ejected. gas.
In this way, the height loss of Zhan-6 will be much more controllable.
