"There is no problem with anti-aircraft missiles!" Professor Su said: "The missile requires minimal changes. Its range is originally about 10 kilometers, which means it hardly needs to be changed. We only need to change the pylon of the fighter jet so that it can
Just launch anti-aircraft missiles..."
"No!" Wang Xuexin interrupted Professor Su: "What needs to be changed in anti-aircraft missiles is the fuze issue!"
"The problem with the fuze?" Professor Su asked in confusion: "Captain, are you talking about the proximity fuze?"
"Yes!" Wang Xuexin said: "It is the proximity fuze. Maybe there will be no problem in using it now, but now the proximity fuze is no longer a secret. We can think of using ultrasonic waves to detonate the proximity fuze in advance. In the future, there will be
The Japanese will also be able to think of it one day! What do you think will happen then?"
All the R&D personnel present at the meeting were frightened by Wang Xuexin’s words.
This is indeed a major weakness of anti-aircraft missiles. The detonation method of its proximity fuse is too simple. It only relies on ultrasonic waves to roughly measure the target range and detonate it at the appropriate time.
The simple weakness is that it is easy to counterattack. The Eighth Route Army fighter planes used this trick to prevent the Japanese anti-aircraft missiles from posing a threat to them.
However, strategies on the battlefield often have two sides.
The Eighth Route Army used this tactic to catch the Japanese by surprise and took advantage of it, but at the same time, the Japanese would also wonder: Why do the same missiles launched into the air by our army always explode in advance and fail to damage the Eighth Route Army fighter planes? They did this in the missiles
What hands and feet?
Maybe the Japanese didn't figure it out so quickly, so the Eighth Route Army could still use it for a while.
But if the Eighth Route Army is not prepared to still use radio proximity fuses or even use them to produce air-to-air missiles... One day the Japanese know this tactic, does it mean that all the Eighth Route Army's air-to-air missiles are useless?
At that time, the Eighth Route Army's fighter planes only carried air-to-air missiles and only had a few machine guns. They even did not carry machine guns in order to reduce weight. Was that just a passive attack?
Will the pilots of the Eighth Route Army neglect to use machine guns in dogfights because of the availability of air-to-air missiles?
At that time, it will not only be a problem that the air-to-air missiles are ineffective, but also a problem that the Eighth Route Army Air Force will have to change back to machine guns in a hurry and fall into complete passivity.
Professor Su thought for a while and then said: "But Captain, besides using proximity fuses, are there any other fuses we can use?"
This question is also something other researchers want to ask.
Anti-aircraft missiles are quite special. Their targets are high-speed flying fighter aircraft, which makes it difficult for anti-aircraft missiles to directly hit the target. This determines that they are not suitable for use with impact fuses.
But apart from the impact fuze, there are only delay fuzes and proximity fuzes... If even the proximity fuze cannot be used now, should we reuse the delay fuze to manually adjust the explosion time?
This is obviously impossible because delay fuzes are less efficient than proximity fuzes.
Wang Xuexin only said: "We now have another more advanced rangefinder, why don't we use it to upgrade the proximity fuze?"
Su Liguo understood when Wang Xuexin reminded him: "Laser rangefinder?"
"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 the ultrasonic waves to lasers, and then you can implement a laser-based proximity fuze.
!”
This is actually a modern "semi-active laser proximity fuze". The principle is similar to that of an ultrasonic proximity fuze. The only difference is that the ultrasonic wave is changed to forward and several circumferential laser beams.
It is not difficult for the Eighth Route Army to produce it. It just needs to further miniaturize the laser rangefinder and make it into a fuze.
What Wang Xuexin didn't notice was that when he expressed 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 could be used to make fuzes instead of ultrasonic waves? Only the leader could think of it.
?
After a while, Su Liguo broke everyone's awkwardness with a "hmm".
"I think this method is feasible!" Su Liguo said: "For a fuse, we only need a few small laser beams, and its calculation method is also very simple..."
After saying that, Su Liguo turned his attention to Chen Jiefeng.
Chen Jiefeng nodded firmly: "Yes, the proximity fuze only needs to compare the distance received before and after. Once the distance becomes larger, it will detonate. Only a few transistors can complete this operation!"
"No!" Wang Xuexin objected: "We should make its calculation method more complicated. In the past, there was no condition. Now that transistors have this condition, we should make air-to-air missiles safer and more reliable!"
Su Liguo swallowed his saliva and asked, "For example..."
"For example, we need to add a self-destruction program for air-to-air missiles!" Wang Xuexin analyzed: "After all, the target of air-to-air missiles is fighter aircraft. In combat, it is easy for the missile to be launched and the enemy aircraft has left the detection range. At this time, the missile is easily
Accidentally damaged our own fighter plane!"
Everyone couldn't help but nod their heads after hearing this.
This is not Wang Xuexin’s random talk, but anti-aircraft missiles have reported such problems in actual combat... Eighth Route Army fighter planes were shot down twice by our anti-aircraft missiles.
Afterwards, based on interviews with the pilots, researchers believed that this was probably because the anti-aircraft missile failed to track the target after it arrived at the designated area. However, it did not self-destruct and continued flying, and then tracked the Eighth Route Army's own fighter jets...
Therefore, the self-destruction procedure is very important, which can reduce the accidental damage rate of anti-aircraft missiles.
Chen Jiefeng nodded and said: "This is not difficult, just add a self-destruction 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. At this time, there is no need to wait for the moment the target flies away!"
The reason is very simple. The circumferential laser beam goes around 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?
that moment?
Chen Jiefeng nodded again and said: "This is 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 implement these, but it is difficult to think of...!
