"There is no problem with the anti-aircraft missile!" Professor Su said: "The missile needs to be modified the least. Its range is about 10 kilometers. Launching anti-aircraft missiles is..."

"No!" Wang Xuexin interrupted Professor Su: "What needs to be changed for anti-aircraft missiles is the fuze issue!"

"The fuze problem?" Professor Su asked puzzledly, "Head, are you talking about the proximity fuze?"

"Yes!" Wang Xuexin said, "It's the proximity fuze. Maybe it won't be a problem to use it for the time being, but it's no secret that the proximity fuze is no longer a secret. We can think of using ultrasonic waves to detonate the proximity fuze in advance. One day devils can also think of it! At that time, what do you think will happen?"

All the R&D personnel attending the meeting were frightened by Wang Xuexin's words.

This is indeed a major weakness of anti-aircraft missiles. The detonation method of the proximity fuze is too simple. It only relies on ultrasonic waves to roughly measure the distance of the target and detonate at the right time.

The weakness of simplicity is that it is easy to counter it. The Eighth Route Army fighter planes used this trick to prevent the devil's anti-aircraft missiles from posing a threat to it.

However, tactics on the battlefield often have two sides.

The Eighth Route Army did catch the devils by surprise and took advantage of it by surprise, but at the same time the devils would also think: Why are the missiles launched by our army always explode early and fail to hurt the Eighth Route Army fighter planes?What did they do in the missile?

Maybe the devils didn't figure it out so quickly, so the Eighth Route Army can still use it for a while.

But if the Eighth Route Army is not prepared to still use radio proximity fuzes or even use it to produce air-to-air missiles... One day the devils know this tactic, does it mean that all the air-to-air missiles of the Eighth Route Army are useless?

At that time, the fighter planes of the Eighth Route Army only had a few machine guns in addition to carrying air-to-air missiles, and they didn't even carry machine guns to reduce weight. Was it just a passive attack?

Will the pilots of the Eighth Route Army be negligent in dogfighting with machine guns because of the presence of air-to-air missiles?

At that time, it will not only be a problem of ineffective air-to-air missiles, but also a problem that the Eighth Route Army Air Force will rush back to machine guns and become completely passive.

Professor Su thought for a while and said, "But the leader, besides the proximity fuze, are there any other fuzes we can use?"

This question is also asked by other researchers.

The anti-aircraft missile is quite special. Its target is a fighter plane flying at high speed, which makes it difficult for the anti-aircraft missile to hit the target directly, which determines that it is not suitable for using a touch-and-explode fuze.

But apart from the touch fuze, there are only delay and proximity fuzes... If even the proximity fuze can't be used now, should the delay fuze be used again to manually adjust the detonation time?

This is obviously impossible, since time-delay fuzes are less effective than proximity fuzes.

Wang Xuexin only said: "We now have another more advanced range finder, why don't we use it to upgrade the proximity fuze?"

As soon as Wang Xuexin reminded Su Liguo, he understood: "Laser range finder?"

"Yes!" Wang Xuexin said: "Ultrasonic waves may be interfered by the enemy, but lasers will not be interfered, right? Using the same principle, just change ultrasonic waves to lasers, and then you can realize the proximity fuze based on lasers." !"

This is actually the modern "semi-active laser proximity fuze", the principle is similar to that of the ultrasonic proximity fuze, the difference is that the ultrasonic wave is changed to several laser beams in the forward and circumferential directions.

It is not difficult for the Eighth Route Army to produce it, but the laser range finder needs to be further miniaturized to make a fuze.

What Wang Xuexin didn't notice was that when he said this idea, everyone in the conference room looked at him in shock, including Su Xin.

At this time, the researchers were thinking about a question: We obviously have proximity fuzes and laser rangefinders, but why didn't everyone here think that lasers can be used instead of ultrasonic waves to make fuzes?Only the leader can think of it?

After a while, Su Liguo let out a "hmm" to break everyone's embarrassment.

"I think this method is feasible!" Su Liguo said: "For a fuze, we only need a few small laser beams, and its calculation method is also very simple..."

After speaking, Su Liguo turned his gaze to Chen Jiefeng.

Chen Jiefeng nodded affirmatively: "Yes, the proximity fuze only needs to compare the received distance before and after. Once the distance becomes larger, it will be detonated. Only a few transistors are needed to complete this operation!"

"No!" Wang Xuexin objected: "We should make its calculation method more complicated. It used to be unconditional, but now with transistors, we should make air-to-air missiles safer and more reliable!"

Su Liguo swallowed, and asked, "For example..."

"For example, we need to add a self-explosion program for air-to-air missiles!" Wang Xuexin analyzed: "After all, the target of air-to-air missiles is fighter planes. Injure our own fighter plane by mistake!"

Everyone couldn't help nodding their heads.

This aspect is not just nonsense by Wang Xuexin, but anti-aircraft missiles have reported such problems in actual combat... There were two battles where the Eighth Route Army fighter jets were shot down by our anti-aircraft missiles.

Afterwards, based on interviews with the pilots, the researchers believed that it was likely that the anti-aircraft missile failed to track the target after reaching the designated area, but it did not explode at the same time, so it continued to fly, and then tracked the Eighth Route Army's own fighter plane...

Therefore, the self-detonation procedure is very important, which can reduce the fratricide rate of anti-aircraft missiles.

Chen Jiefeng nodded and said: "It's not difficult, just add a self-detonation condition: detonate if no target is detected within the predetermined time range!"

"Also!" Wang Xuexin added: "If multiple laser beams detect the target at the same time, it proves that the missile is close enough to the target, and there is no need to wait for the moment when the target flies away!"

The reason is simple. The circumferential laser beam circles the fuze. Only when the target is close enough can several laser beams detect the target at the same time. This is the best time to detonate. Why wait until the detection distance becomes larger? Moment?

Chen Jiefeng nodded again: "It's not difficult, just calculate the number of effective detection laser beams and use this as the detonation condition!"

Chen Jiefeng's words left everyone present speechless.

It is indeed not difficult to realize these things, but to think of... that is difficult!
