Chapter 1334 Proximity Fuze
At this time, air-burst bombs have actually been developed by many countries or have experience in research and development, because everyone knows that air-burst can double the lethality...The shell explodes in the air instead of plunging into the soil and explodes in a radial manner. , its shells will fly around with terrifying kinetic energy, and they are numerous and dense, and they are more lethal.

However, without exception, these research and development all ended without a problem.

The reason is that it is very difficult to achieve an airburst, especially a proper airburst a few meters above the target.

In this era, there are mainly two ways to achieve air explosion:

One is a long-rod fuze, as the name implies, a long rod like a lightning rod is installed in front of the fuze.

This method is simple and effective, but there are many problems... The air blast distance is only the length of a long rod. If it is too short, it will have no effect at all. If it is too long, it will affect the flight of the shell in the air and even be accidentally detonated, so it was quickly eliminated.

The other is the delayed fuze.

The delayed fuze is much safer. In theory, it only needs to calculate the landing time of the shell and detonate a little earlier to achieve the effect of air explosion.

But it is very difficult to talk about Kongyi and actually do it.

The reason is that the muzzle velocity of the projectile reaches more than 500 meters per second. Although the speed of the shell is reduced by air resistance when it lands, it still has a speed of 400 meters per second.

When the projectile can fly three to 400 meters in one second, how can the delay fuse be used to make the projectile explode a few meters earlier?
The distance of these meters is calculated as one hundredth of a second in time. What kind of delay lead can be accurate to one hundredth of a second?

In addition, can the landing time of the shell be calculated within a second?
Can each shell suffer the same resistance in the air?

If these are not accurate, what is the best effect of airburst?
The result is both laborious and unflattering... I originally hoped to increase the lethality by installing a delay fuze, but in actual combat, I found that either the detonation was early or the detonation was late, and few shots that could really achieve the desired effect, but the lethality was on the contrary. Not as good as ordinary shells.

But this problem is not a problem for Wang Xuexin...

Wang Xuexin sent a telegram to Su Liguo, asking, "Can the proximity fuze be self-produced?"

Su Liguo was a little strange about Wang Xuexin's question.

Because the Eighth Route Army’s demand for proximity fuzes is not particularly large, the main use of this thing is to install it on anti-aircraft artillery shells. It can save the gunner the steps of adjusting the delay fuze to improve combat effectiveness.

But the Eighth Route Army still doesn't have a few anti-aircraft guns... Dozens of imported anti-aircraft guns are equipped near the airport, but few are better than nothing.

The proximity fuzes of the Eighth Route Army are mainly used on missiles, including air-to-air missiles.

However, the proximity fuze imported from Yingjiang was enough to meet the demand, and it has not been used up to half, and it can continue to be imported from Yingjiang at any time... Why is the leader so anxious to ask if he can produce it himself?

However, although he was puzzled, Su Liguo still replied: "There is no problem with self-production, but we need to use small electronic tubes!"

The reverse research and development of the proximity fuze has already started. Su Liguo has figured out its principle before, and it is not a high-tech thing if he can produce his own radar.

Wang Xuexin replied without thinking: "I will start self-production immediately, but the target is not the enemy plane, but the ground. Is there any problem?"

"No problem!" Su Liguo replied with certainty.

This is not a difficult task, in fact, as long as the proximity fuze of the eagle sauce is completely imitated, and then the sensitive band is changed, just like the ground mapping radar of the eagle sauce.

Su Liguo didn't know the use of Wang Xuexin's ground-sensitive proximity fuze at first, but he understood after receiving a few fuzes and blueprints...

Su Liguo worked in an arsenal and knew that the Eighth Route Army had recently introduced a batch of howitzers. After contacting the fuze sent by Wang Xuexin, it was easy to guess that it was the howitzer fuze.

"Why does the howitzer fuze use a proximity fuze?" Su Liguo said to himself while looking at the blueprint, "And it's also ground-sensitive!"

After thinking for a while, Su Liguo suddenly thought of something:
Proximity detonation of the fuze, does that mean that it will be detonated when it is close?
If it hits the ground and then explodes, it doesn't make any sense, that is... air blast?
Thinking of this, Su Liguo couldn't help but scream: "A master! Use the proximity fuze to solve the problem of air explosion. Even Yingjiang with the proximity fuze didn't think of this! As expected of the leader, he casually solved a world-class giant. problem!"

Wang Xuexin did use melee fuzes to achieve air explosions.

Problems that cannot be solved with a delay fuze, such as a hundredth of a second, are not a problem at all with a proximity fuze.

However, there are still some differences compared to the proximity fuze used by anti-aircraft guns.

The reason for anti-aircraft gun shells is that the closer the projectile is to the target, the better. The detonation point is the moment when the detection distance changes from near to far.

The shells used for air blast must not use this detonation point, otherwise they will plunge into the soil and explode like ordinary bombs.

This requires Su Liguo to test the self-produced radar, that is, the signal strength it receives when the radar is about five meters away from the ground.

Because the strength of the radar signal reflected by the ground is similar, this can be used as a reference point, which is the detonation point.

Su Liguo's test results are... due to the low precision of the self-produced radar, there is a certain error in the strength of the received signal. It is recommended to set the detonation point at 10 meters.

Wang Xuexin estimated that a modern building has a floor height of about 3 meters, and 10 meters is higher than a three-story building. This height is also suitable for air blasting, so he agreed without thinking too much.

It was later found that the lethality of a 10-meter airburst may be higher than that of a 5-meter airburst.

The reason is that Wang Xuexin underestimated the power of the M30 shell, and worried that the high altitude would affect its lethality. Power, and a speed of 400 meters per second.

With this speed plus the force of the shrapnel when it exploded, it would basically be dead if it hit the target below. The point is that its killing range has been expanded by more than two times.

If there is such a blessing of shells, Wang Xuexin believes that a regiment with 12 howitzers and a gun detection radar can solve most of the problems.

In fact, using this kind of proximity fuze can not only hit infantry, but also hit enemy artillery...

Wang Xuexin couldn't help but think that the shrapnel that exploded in the air should kill the enemy's artillery but not hurt the artillery. In this way, the enemy's artillery can be completely captured. Wouldn't that be a beautiful thing?
