Chapter 856: One frame is playable, two frames are smooth
"However, in order to maintain stability, it is necessary to install this kit above the bomb, and the height from the ground must also be considered."

Gao Zhendong looked at him and shook his head: "Don't worry about the height from the ground."

"No way? The thickness of this kit shouldn't be too small, right?" Mr. Zhang also felt that the comrade who worked on pneumatics was right.

"Because you can install the navigation kit on the side, and just let it turn halfway when dropping the bomb. If there is enough space, you don't have to install it on the top, you can install it on the bottom. In this way, you don't have to consider the attachment of the kit to the aircraft at all, just use the bomb itself. Um, have you seen the clamps commonly used in factories? Just use that thing to hold the kit on the bomb."

Gao Zhendong's words made Mr. Zhang and the others feel like fools.

The comrades around him also thought that they were fools. At first, most people thought that what the comrades from Chunlei Factory said made sense.

In this matter, they did not sigh at Gao Zhendong's cleverness, but rather sighed at their own stupidity for not being able to think of such a simple thing.

"Remember, this is a modification kit. As long as you can achieve the desired effect, you can do it in any convenient way." Gao Zhendong said with a smile.

With Gao Zhendong's words, the comrades found the key to the problem.

"Then you don't need to think too much about the automatic deployment device of the wing. The mechanical spring will pop open and lock it. It is usually tied with a cable tie. When it is deployed, the tilt switch can be used to trigger the explosive bolt."

"The switch doesn't need to be too precise, it just needs to be roughly right, and the flight control system will correct the flight attitude after deployment."

"Then use a mercury switch and make the trigger angle smaller. It's simple, cheap and reliable." Mercury is not cheap, but the amount of a mercury tilt switch is nothing compared to a complex control system.

"Will the mercury switch be accidentally triggered by the vibration of flight?"

"Make the mercury pool deeper. If you're really worried, add a valve plate that opens only when the transmitter is powered on. It's very simple."

The Air Force was grinning from ear to ear, but the other civilian cooperation units were secretly shocked. It turned out that this is how military equipment research and development is done. Are these big guys so awesome?

If other people knew what they were thinking, they would tell them. This is not usually the case. Today's situation is special.

"Hey, I remember seeing a new invention of the Citigroup guys. That thing is good. If you use that, the clamps for the 1-ton bomb and the 500kg bomb are the same, universal. Plus, this component has autonomous flight control capabilities. In fact, as long as the upper limit of the bomb caliber is met, the 1-ton bomb and the 500kg bomb can actually use the same kit, or even the same set of connectors."

A structural staff member of Chunlei Factory made a very good suggestion. It can be seen that this comrade is constantly enriching himself in his work.

The fact that you know about the new inventions of the Citigroup guys speaks volumes. Although Zhenxing Electronics and other channels are constantly bringing foreign technical information into China, you still have to learn it yourself before you can bring it in.

His suggestion is not without reason. The bomb is too light? Then I can press the control surface and adjust it to adapt it actively.

Everyone looked at Gao Zhendong, not because they were superstitious, but because he was the only one who knew best what the consequences of replacing the connector would be.

When Gao Zhendong heard this, he was delighted. This comrade's words made sense and were feasible, just like a glider with a load of 1 ton could carry 1000 kg or 500 kg. In fact, both could be carried.

"Then your flight control work will be very heavy, haha." Gao Zhendong said with a smile.

Seeing that Gao Zhendong did not object to his colleague's suggestion, the comrade in charge of flight control was very excited: "Don't worry, Mr. Gao, we are not afraid of hard work and will definitely make the universal flight control of this kit well."

Gao Zhendong nodded: "That's fine, you guys go in that direction. But give priority to those over 1 ton, after all, this may involve wind tunnels and other work. By the way, tell us about that new invention."

The reason for asking this is mainly to confirm the applicability of this new invention.

After hearing Gao Zhendong's words, the comrade in charge of the design drew the invention on the blackboard.

In fact, this is the world's first cable tie, invented by Maurus C. Logan in 1959 and patented in 62. But since it is the first one, it is bound to have defects.

It is not impossible to realize this comrade's idea, but it is still a little lacking.

After Gao Zhendong finished reading it, he said something that shocked the comrades: "Ah, so this is the structure, I understand. This thing is not quite good enough, I will modify it for you, it is guaranteed to be better than this one, let's use our own and not take advantage of the Citigroup guys, hahahaha."

No, are you that fast? Can you improve just after reading it? And this is mechanical stuff, it has nothing to do with your area of ​​expertise.

Is the gap between people so big?

Gao Zhendong then used facts to prove to them that indeed there was, and that I was a cheater.

Gao Zhendong stood up and drew a schematic diagram of the stainless steel binding strap clamp that was commonly used later on the blackboard. He didn't even need to search for this thing because he had used it before and the structure was simple. He could draw a schematic diagram at will. For comrades who were engaged in structural work, having a principle was enough.

Looking at the diagram drawn by Gao Zhendong, the comrade who worked on the structure was completely muttering to himself, "This one is indeed better than that one, and is more suitable for high-hardness materials such as stainless steel."

Logan's invention requires the cable tie to be folded 90 degrees more than twice, which is a big problem for steel, as it is difficult to self-tighten. However, Chief Engineer Gao's cable tie moves forward flat all the way, and self-tightening can be easily achieved by twisting the self-tightening bolt.

"Yes, and with this structure, the protruding part of the cable tie is smaller, and it is easier to apply force during the self-tightening operation."

"Hey, this is good. I want to use it for other things."

"..."

Seeing Gao Zhendong's improved operation on the spot, the comrades were full of admiration.

Gao Zhendong smiled and said, "This is a universal fastener. You can use it wherever you want. Go back and think about it. You can make more specifications for different occasions. Remember to apply for a patent from the Bureau of Standards and Regulations and come up with some standards. It will also be good for your factory."

I never expected that a topic could give rise to a small topic.

No matter how simple it is, don't forget that our first batch of standards are almost all about industrial basic parts such as screws.

Just this thing is enough for some comrades to eat for a lifetime, and this statement is not an exaggeration at all.

Gao Zhendong thought about it and drew another type of cable tie - a nylon cable tie.

"I remember that the Citigroup people have another design. You can try this one too. It has good wiring. I'm sure the comrades who work on aircraft and electromechanics will like it."

The invention of cable ties was prompted by the need for aircraft wiring. Those who work in aircraft and electromechanical engineering will definitely like it.

Gao Zhendong usually couldn't remember such small things, but now that he remembered it, he might as well make it out. Gao Zhendong copied it without any psychological burden. In fact, the first nylon cable tie was invented by a Citigroup employee in 1958.

Mr. Zhang from Chunlei Factory was so happy that he couldn't stop smiling. How could he be so embarrassed? The first inventor of this thing must be Chief Engineer Gao, but it can solve many difficult problems in the factory. As for nylon cable ties, Mr. Gao said that the Citi people have already made it, so even if we imitate it, we can solve some of the performance of low- and middle-level technicians.

"Don't worry, Chief Engineer Gao, we will definitely complete the task well." General Manager Zhang immediately patted his chest.

"Well, this is just a small matter, you can handle it. Now, do you have any concerns about this TV-guided bomb?"

There is nothing wrong with 1274. For them, all they have to do is copy Gao Zhendong's design and perfect the craftsmanship.

A comrade from another unit, after intense and complicated calculations, finally raised his doubts at this time.

"Chief Engineer Gao, the prerequisite for this guidance method is to be able to basically stably transmit television signals with a certain quality, right?" They are comrades who are engaged in television broadcasting equipment. There is no other reason for calling them here, just to do it quickly.

"But we just calculated that we can't stably transmit TV signals within a range of 45 kilometers, even using analog transmission. It's too far."

Generally speaking, the distance of low-bandwidth analog transmission is longer than that of high-bandwidth digital transmission. In fact, there is no need to do too detailed calculations. Under the same other conditions, according to Shannon's theorem, the transmission distance of large bandwidth must be shorter.

Gao Zhendong did not think about digital transmission first, which was the biggest reason. He wanted to be fast! He put digital transmission aside and used analog transmission first.

But a distance of 45 kilometers is still a bit beyond the scope for these comrades. The biggest problem is that the limited space on the kit is not enough for them to do anything.

"The space inside the kit is limited, so the power and antenna cannot be made larger. Even if the power and antenna are increased, 45 kilometers is still beyond our capabilities."

When the other comrades heard this, they felt disappointed again. Well, this is the biggest problem, and the others are not problems.

Only the chief engineer of the Defense Work Committee and the comrades of the Air Force were not moved at all. This was a technical issue, right? Then there was no problem. They knew Gao Zhendong's style better than anyone else.

"I know, I was just about to tell you this. The TV signal you transmit should be 400 lines and about 25 frames per second, right?" Gao Zhendong said with a smile.

"Yes, that's right." This is public, and anyone who has studied this aspect knows it.

"But for TV guidance, I don't need you to transmit such a signal. The resolution only needs 300 or even 200 lines. Four frames per second is best. If that doesn't work, one frame per second will also be fine. Can you do that?"

The saying “one frame is playable, two frames are smooth, and three frames are e-sports” is very valuable here.
