Bright Sword: I took Li Yunlong to work in military industry

As a participant in the Huangliangou air battle, Yang Xing understood too well the significance of this new type of artillery shell that did not hit the target but exploded prematurely.

Most artillery shells today are either impact-fuzed or time-delay-fuzed.

The former needs to collide with the target to be triggered, while the latter can only set a predetermined detonation time. Sometimes the time is too long or too short and it is impossible to hit the target.

Now Minister Yu brought the new type of fuse developed by Zhang Ying. Yang Xing saw clearly that it exploded when it was about 5 meters away from the target.

So a big hole was not blown in the wooden target board, but it was penetrated by the flying shrapnel.

"What the hell?"

Yang Xing stared at the target board in amazement. He was an elite warrior on the battlefield, and through this he could already foresee that if this thing was used to organize anti-aircraft firepower, these shells would explode when approaching the aircraft, and the shrapnel would interweave in the air to form a very dense shrapnel net.

All Japanese planes that fall into this net will be shot down.

Horror!

"Captain Yang, why don't you try it too? See if you can trigger the fuse of this shell by shooting at the target at this small angle?"

Yu Ye stood in the distance and shouted to Yang Xing, the commander of the independent regiment's artillery battalion.

"Yes!"

Yang Xing responded immediately.

From the perspective of his gun position, the inclination angle between the shell and the target was only about 10°. It can be said that it would be easy to miss if one was not careful, and the shell thus deviated from the target.

Yang Xing held his breath and fired at the target 400 meters away.

thump.

The shell flew out of the barrel and shot towards the target 400 meters away.

boom!

However, in the blink of an eye, the shell exploded about 3 meters away from the target, and the expected situation of a big hole being blown out did not occur.

Yu Ye carefully examined the target board in the distance through a telescope and nodded approvingly: "Zhang Ying, the proximity fuze you developed can now be put into mass production."

After saying that, Yu Ye walked directly towards the target board in the distance. He wanted to personally evaluate the destructive effectiveness of the shell.

As soon as he took two steps, Li Yunlong and Yang Xing judged the purpose of their work and directly shook the anti-aircraft guns they were operating from the horizontal firing state. Even though there were no shells loaded inside, they were both worried about accidents.

At the same time, Li Yunlong arranged for the soldiers of the Liangshan Special Forces to watch the anti-aircraft guns and absolutely did not allow any danger to occur.

Yu Ye, accompanied by Li Yunlong, Yang Xing and other soldiers, brought Zhang Ying to the target board. When they saw the target board's appearance after being bombed, they all gasped.

I saw that the wooden board, which was 30 centimeters thick, was full of holes. When I got closer, I saw that the target board was hit so hard that wood chips were flying everywhere.

Nowadays, the Japanese planes are all made of iron sheets. No one present dared to imagine how much damage would be caused to the Japanese plane if the shell exploded at a distance of 3-5 meters.

"Minister, the shell you designed is quite fierce."

Yang Xing looked up at the target board that had been blown into a hornet's nest. He had already imagined himself operating the anti-aircraft gun to shoot the Japanese planes in the face.

Yu Ye shook his head and said with a smile: "Captain Yang, you are wrong. This proximity fuse was not designed by me. It was designed by my student Zhang Ying."

As he spoke, Yu Ye looked at his students with approval.

"Boss... Director, I don't dare take credit for this. Without your advice, I would never have been able to design such an advanced weapon."

Zhang Yingzui almost called Yu Ye "teacher" again, but at the moment he was about to say it, he suddenly remembered that this was a workplace and he should address him by his title.

"Hahaha, don't be so modest in front of me!"

"Tell me about your overall design idea. I have disassembled the prototype of the proximity fuse you made before. It is quite methodical."

Yu Ye is conducting the final inquiry on his students.

"Teacher, my overall idea is still the Doppler effect you mentioned before. At the beginning, we discussed that it is unrealistic to use the electromagnetic signal generated by the target itself.

So, I thought, what if the shells themselves can generate electromagnetic signals?

When the electromagnetic signal generated by the shell itself encounters an obstacle, it will be bounced back. If there is a device inside the shell that can sense it, an induced current can be generated.

If this induced current is amplified, it can detonate the shell."

Zhang Ying briefly explained the entire design idea. Yu Ye could tell that although it was explained very simply, the ingenuity of the design idea was beyond the imagination of ordinary people.

In fact, in another timeline, after the English team completed the design and handed it over to the Americans, the Americans gathered their top laboratory senior engineers at the time to build this thing. At this moment, it is still the most confidential top weapon, and it was not used until the outbreak of the Pacific War.

"Tell me more about your design!"

Yu Ye wanted to test the level of his student again and at the same time give him a chance to show himself. Young people always need to have their own edge.

Zhang Ying became excited when he heard this. It would be meaningful if his masterpiece could get the teacher's complete recognition.

He directly pulled out an uninstalled proximity fuse from his pocket and showed it to Yu Ye on the spot, disassembling it and explaining it at the same time.

"Teacher, look, this is the fuse shell we made of plastic. The top one is the antenna that transmits the electromagnetic signal, and the circles next to it are the induction coils.

The one in the middle is a glass bottle that contains sulfuric acid. Next to the glass bottle are lead sulfate and lead oxide materials produced by our own chemical plant.

When the shell is fired, there is a huge acceleration in the barrel, which will inevitably shatter the glass bottle inside. The sulfuric acid will form a chemical battery with the lead oxide and lead sulfate. "

Zhang Ying dismantled the fuse while demonstrating it to Yu Ye.

"Hahaha, now you're not going to put a generator in the fuse of the shell?"

Yu Ye joked.

Zhang Ying smiled a little embarrassedly. He was indeed a little crazy at that time and even forgot that he could use the battery directly as a power source.

"No, no. When this lead-acid chemical battery is able to supply power, the current will flow along the wires into the components above. The triode oscillation circuit composed of capacitors and resistors will generate alternating current and eventually emit electromagnetic waves.

When the electromagnetic wave encounters an obstacle and is bounced back, it will interact with the induction coil to generate an induced voltage. The closer the distance, the higher the frequency of the electromagnetic wave will become under the Doppler effect, and the higher the induced voltage generated will also be.

Once the threshold we set is exceeded, the detonating capacitor and firing cap will be connected, and the shell will explode."

Zhang Ying introduced his work with great enthusiasm, and Yu Ye saw a rare look of excitement on his student's face that was rare among military workers.

Yu Ye took the fuse and asked his apprentice a question: "This thing of yours is sulfuric acid in a glass bottle. Aren't you worried that during transportation, the sulfuric acid bottle will break and explode directly?

Aren't you afraid that you might blow up our own people instead of shooting down the enemy's planes?"

Hearing these words, Li Yunlong and Yang Xing, who were beside Yu Ye, were all shocked. When they thought about the fact that they were sitting on a pile of shells that could explode at any time, they broke out in cold sweats.
