Chapter 413: Detailed Method of Making Proximity Fuze
"Zhang Ying, since you said that many precision components cannot withstand 2 gravitational accelerations and 3 to 5 revolutions per minute, why don't we change our thinking?"
Yu Ye took apart a simple collision fuse and placed it in front of Zhang Ying.
"Change your thinking?"
Zhang Ying didn't quite understand what his teacher said.
"That is, we do not regard this extreme environment as an obstacle, but rather as a condition for triggering the fuse."
Yu Ye explained.
Zhang Ying took out a small notebook and carefully wrote down every word Yu Ye said.
"Zhang Ying, you are a student majoring in physics. You must have learned about the Doppler effect and electromagnetic induction, right?"
"I have learned it, teacher, no, factory director!"
Zhang Ying knew that he was working at that time, so he corrected his address very seriously.
"If there is a target of ours, let's assume it's a Japanese plane or fortification, and there is an electromagnetic signal transmitted to the artillery shells, if it can be sensed by the artillery shells, and used as a signal to detonate the artillery shells, is it feasible?"
Yu Ye patiently and patiently guided his student.
"Yes, Director. But how can we make the enemy's planes or fortifications send out electromagnetic signals? How about we install one for them?"
Yu Ye was almost choked to death by this sentence, and he rolled his eyes at the student: "I just want to ask you a question. A group of mice made a bell and said they would hang it on the cat, so that when the cat comes out to catch these mice, the mice can get the information in advance.
The question is, which mouse should hang the bell?
How about you be the mouse?"
When Zhang Ying heard this, cold sweat broke out on his body. Although the teacher was mocking him, what he said made so much sense. It was impossible for us, the comrades of our independent regiment, to place signal transmitters on the Japanese planes and fortifications.
"What should I do?"
"What should we do? Can't we just let the shells send signals themselves?" Yu Ye said.
"Ok?"
Hearing this, Zhang Ying's eyes suddenly lit up.
"Old... Director, you mean to let the shells emit electromagnetic signals themselves, and then when the electromagnetic signals hit the target, such as the enemy's planes or fortifications, these electromagnetic signals will be reflected back.
In this way, if the signal receiving device on the shell receives the reflected information, it can initiate the detonation.
Look, am I right?"
Inspired by Yu Ye, Zhang Ying immediately figured out the key and excitedly told Yu Ye about it.
Yu Ye nodded approvingly. This guy understood things very quickly and was worth training.
"Doppler effect, electromagnetic induction..."
Zhang Ying muttered to himself, and seemed to have some inspiration.
"Teacher, if we add an induction coil to the front end of the shell, when the reflected electromagnetic signal passes through the induction coil, it will generate an electric field and form a voltage.
This way, there is a very clear signal!"
Zhang Ying's eyes became brighter and brighter. After he had an idea, this method was like diabetes insipidus, which could not be stopped.
"Also, teacher, if we can measure or empirically know the speed of the projectile at different distances, when it passes by the reflected electromagnetic signal, we will know the voltage threshold formed by different reflection distances.
In this way, we can adjust the distance between the explosion point of the shell and the target!"
Zhang Ying became more and more excited as he spoke, and his thoughts became completely clear.
Yu Ye looked at Zhang Ying, and the approval in his eyes became more and more intense. This little guy is not bad.
"Then what about the device that generates this signal?"
At this moment, Zhang Ying no longer had Yu Ye in his eyes, and his eyes were not even focused. His brain had gone into a crazy state.
"For electromagnetic signals to occur, this thing must have electricity. No matter how small the generator is, it is impossible to stuff it into the shell."
Zhang Ying muttered to himself, completely immersed in his own world.
Yu Ye's mouth twitched as he listened nearby. Stuffing the generator into a cannon shell, this guy is the only one who can think of this, it's simply a wild idea.
Moreover, even if it can be stuffed in, how much would the shell cost?
One artillery shell costs one micro generator. This isn't war, this is just throwing money away.
Not to mention Lao Li, the brigade commander and the commander are going to tear themselves to pieces because they are such a waste.
However, Yu Ye did not stop his apprentice's crazy ideas. Many technological inventions in history originated from these seemingly crazy ideas.
The industry is even happy to see their students have such ideas, which can promote the development of the entire technology.
There are design ideas about the proximity fuse in Yu Ye's office drawer, but the parameters and dimensions of each part are not precise. However, he does not intend to show this material to Zhang Ying. He hopes that Zhang Ying can figure it out based on his own ideas.
One Dharma can pass, all Dharmas can pass.
Now that the ideas and principles have been sorted out, the only thing left is a matter of time. Even if Zhang Ying's final ideas go astray, the worst that can happen is that I will show him the materials again.
Any design ideas that go astray should be considered as accumulating experience.
Yu Ye chose to hand over the matter of the proximity fuse to Zhang Ying. In fact, there was another consideration. This kid's qualifications were not as good as Guo Shoujue, Li Zhengang and Li Junhua, but this guy had a very outstanding advantage, which was that he had enough patience and tenacity. When facing the goals he chose, he would move forward unremittingly, even if it was just one step at a time.
This is actually a rare and valuable ability.
In scientific research, one must either have extremely strong talent or be very resilient and persistent like Zhang Ying. Both types of people can go very far in scientific research.
Currently, when manufacturing proximity fuses, there are many parameters that need to be continuously tested and adjusted according to existing conditions, in order to ultimately reach a very precise value.
This test is not done once or twice, but hundreds or thousands of times. Only in this way can accurate results be obtained.
For a project like this, it would be most appropriate to entrust it to Zhang Yinglai.
Many data of the proximity fuze, including the size of the induction coil for different sized shells and the time of the explosion delay, are very important.
It takes a water grinder to grind it out.
"By the way, Director, this design project may require some transistors or capacitors. We may not be able to produce these components for the time being. Is that possible?"
"purchase!"
Yu Ye said directly and clearly.
"By the way, let me give you another tip. The shell of this fuze cannot be made of metal due to the electromagnetic shielding effect. It is best to use plastic.
I have asked Chen Kan to start looking for ways to conduct research on coal chemical industry and petrochemical industry. It is only a matter of time before we can produce plastics.
If you are quick on your end, try to import a batch of plastics from Shanghai or Hong Kong."
Yu Ye added.
"Thank you, teacher!"
Zhang Ying responded eagerly. He didn't expect that the teacher had already thought of all his possible questions in advance. He was so excited that he didn't even bother to pay attention to the teacher's address.
Seeing that his teacher knew so much about proximity fuses, he had reason to believe that there must be a complete design drawing somewhere in his teacher's office.
