Siheyuan: I eat melons while doing scientific research

Chapter 1175 Semi-active is still useful (4k)

The comrades from the Missile Research Institute laughed and said, "When air-to-air missiles are on the ground, their range is not that high, at least half as high."

Gao Zhendong added: "It's not necessarily halved. It depends on the trajectory planning. Some missiles can fly very far with just a little charge. However, those bullets can't hit any serious fighter planes if they just pass by casually."

When he said this, he thought of the famous Mach 2 missile, the Barak 8, which was held as a treasure by the USS Dirty Three. High-mobility targets were basically out of reach. In other words, the USS Dirty Three, which could not get a good missile and imitated the SA-6 in a mess, was held as a treasure every day, and several serious major countries did not take that broken thing seriously.

Even the most lame John Bull has the "Aster" of the Gallic brothers to use.

"Isn't there a combined anti-aircraft missile being developed?" the Air Force comrade thought of it.

Gao Zhendong shook his head: "The planned range is only about 8 kilometers, so the difference is not too big. The distance is still short. If this is put on land or sea, it can support a range of about 20 kilometers. For field air defense, echelon air defense of key areas or secondary ships at sea, it is still a good low-cost air defense method."

After all, everything can be hit with medium and long-range bullets, so the main focus is on saving where necessary and spending where necessary.

The chief engineer of the Defense Work Committee nodded repeatedly, saying that this made sense.

"Moreover, we all know that the current 30-kilometer surface-to-air missile is only temporary. The range is being increased. When the range is increased, the blank area between medium-range and long-range missiles and short-range missiles will be even larger. It is better to prepare for a rainy day," Gao Zhendong added.

The Air Equipment Bureau just then remembered this matter.

"Well, Comrade Zhendong's suggestion is very good."

This is also a routine operation. For example, from "Sparrow" to "Sea Sparrow", this is the operation. Of course, there is also the opposite. For example, when the Citigroup really does not have a special ultra-long-range air-to-air missile, it will also hang the "Standard" missile on the plane.

The comrades from the Institute of Guidance and Research smiled widely: "Now, we will have work for the next one or two years."

Gao Zhendong shook his head: "I think these small improvements should not be your most important work. I suggest you consider making a big one..."

big?

Speaking of this, the comrades from the Air Equipment Bureau are no longer sleepy: "How big?"

"The long-range missiles have a range of more than 80 to 100 kilometers and a combat altitude of no less than 30 kilometers. Their main combat targets are bombers," said Gao Zhendong.

This indicator can be regarded as a scaled-down version of the AIM-54 Phoenix.

"Bomber? We don't have such a strong demand for long-range bombers, right? The American people are coming here from the sea, and their main means should still be aircraft carriers, but aircraft carriers cannot be equipped with bombers." The comrades from the Institute of Navigation and Research were a little surprised.

The chief engineer of the Defense Work Committee's eyes flashed, he looked up at Gao Zhendong, and then spoke up: "It is still necessary. After all, there are many Citigroup air force bases in the South Peninsula and the Japanese, including the current South Jiaozhi. The long-range strike capability of bombers is still necessary."

As for who Gao Zhendong was thinking of, he actually had a rough idea in his mind, but this kind of thing could be done, but he would rather not say it out loud if possible.

The comrades in the Air Force were quite happy about it. To them, all kinds of weapons were Han Xin's way of using soldiers - the more the better.

I can do without it, but I can’t live without it.

It's just that they are a little worried about our technology.

"We can do it now, even if it's so far away?"

Gao Zhendong nodded: "Don't worry about that. There will be new propellants soon. In addition, we don't need too high terminal maneuverability to attack bombers. We can greatly increase the range by launching a high-altitude trajectory. As for terminal maneuverability, if we really need it, remember the dual-pulse engine I mentioned just now? If we are willing to spend more money to get this thing, we will have no problem attacking fighters at this distance."

In fact, even if the size of the existing Thunder-2 medium-range missile is matched with a suitable propellant, such as the HTPB propellant with a better formula, it can hit more than 100 kilometers, not to mention that comrades may make this missile thicker if they have no other choice.

The comrades in the Air Force's eyes lit up: "Yes, yes, yes, this is it, this is it."

For them, it is so much fun to kill the enemy leader with a flying sword from 100 kilometers away.

The comrades at the Institute of Missile Research did a rough calculation on paper and said, "Well, if we do this, we can really make a missile with a range of 100 kilometers, but it may be difficult for the radar on our aircraft to illuminate that far."

The radars on ships and on the ground are big and powerful, but the radars on aircraft cannot compare with them in terms of size or power, and are limited in their illumination capabilities.

Gao Zhendong laughed and said, "Why don't we focus on the navy's missiles? The planes only need to illuminate or guide the first half of the journey."

The Navy's missiles... Aren't the Navy's air defense missiles all coming from the Air Force and the Army? What air defense missiles do they have?
The comrades from the Air Equipment Bureau haven't figured it out yet, but those from the Research and Development Institute have sort of understood it.

"The Navy... I understand. Commissioner Gao, you mean to learn from the Navy's anti-ship missiles and install radars on them? In this way, the missiles can rely on the radar on them to guide themselves in the second half of the journey?"

Gao Zhendong nodded: "By the way, with a caliber of about 200 mm for this missile, with the latest pulse PD, flat slot antenna and other technologies, it can fit a radar with decent performance. If it is made a little thicker for long-range, there will be no problem. In fact..."

"Actually what?" Usually the following words with this kind of transition are very interesting. And according to Comrade Zhendong's habit, they are usually good ideas.

"In fact, the front and middle stages of this missile can be guided by radio commands, which is much cheaper and the missile-borne radar does not need to consider receiving radiation at all."

Pure radio command guidance, the missile may not even have any proper guidance system, it only needs to receive commands from the rear to adjust its direction.

This thing has no other advantages except that it is cheap and reliable, especially in the case of air-to-air missiles where electromagnetic waves have line of sight almost the entire distance.

Of course, it is not without defects, but these defects are not a big problem if there is an active radar head in the rear section.

"Eh~~~~~yes! This is a good idea. The front and mid-course radio command guidance plus the active radar terminal guidance solve the problem of guidance distance very well. Moreover, the fighter jet in the rear section can completely ignore the missiles and do other things. If there is any flaw, it is that the cost of this system cannot be low." The comrades from the Guidance Research Institute applauded.

The comrades in the Air Force laughed and said, "We still have to pay the money. At worst, we can have less equipment in normal times, but we can't have no equipment at all." Comrade Gao Zhendong is already trying his best to reduce the cost of this missile.

Imagine that in a few years, they will be able to form an air-to-air missile system with a range covering long, medium and short distances, and guidance methods covering infrared, semi-active radar, and active radar. This is something they never dared to think about before. Add to that the laser-guided bombs, TV-guided bombs, and terminal-sensitive bombs for ground attacks, and they will have everything! Nothing is missing!

In fact, it is still missing, but they just didn’t think of it.

"Well, this can be done. We will organize people to promote it later." The chief engineer of the Defense Work Committee nodded frequently. There was no room for refusal on this offer.

"Dual pulse, the main thing is to develop dual pulse, which is very meaningful for medium-range and long-range missiles. And the active radar head, as long as these two things are solved, the rest can just be a matter of piling up materials." The comrades from the Missile Research Institute calculated it very clearly, and here the range became the easiest problem to solve.

The chief engineer of the Defense Work Committee had already thought of the next step: "For the active radar head, you can contact the comrades who are working on radar for fighter jets. They have experience in this area."

"Thank you for the support, leaders." The comrade from the Institute of Guidance and Research smiled as if he was very happy.

The comrades in the Air Force shook their heads and sighed: "We never expected that semi-active radar guidance would be eliminated so soon..." This was something they had never expected. It has only been a few years since the introduction of the unusable K-5, and now even semi-active radar guidance is no longer a priority.

Gao Zhendong shook his head: "No, no, no, semi-active radar guidance is still useful. First, it is relatively cheap. Second, semi-active radar guidance technology can actually be easily converted into another weapon."

The other comrades no longer cared about whether it was cheap or not. All their attention was attracted by the "other weapon" that Gao Zhendong mentioned.

"What weapon?"

Gao Zhendong smiled and uttered a few words: "Anti-radiation missile!"

Anti-radiation missiles? Nuclear radiation? That doesn't matter, right?

Before the comrades could express their doubts, Gao Zhendong explained: "Anti-radiation missiles are weapons that attack electromagnetic radiation sources in the direction of the source of electromagnetic radiation. It can be said that we use the enemy's signals to guide our weapons."

Wonderful! Several comrades almost slammed their hands on the table.

What is the source of electromagnetic radiation? It is just radar!

Today, the status of radar in air defense operations can be said to be supreme. Without radar, the only means available are visual fire with anti-aircraft guns or portable anti-aircraft bombs, which have limited effectiveness.

As long as the enemy's radar can be knocked out, most of the problems will be solved for the offensive air force.

"We have to do this! We have to do this!" Before the Defense Working Committee could say anything, the comrades from the Air Force had already stood up, waving their hands excitedly.

In principle, a semi-active seeker is actually an anti-radiation seeker, but the guidance signal comes from the enemy.

"Of course, this is also somewhat difficult. The most troublesome part is that the seeker of the anti-radiation missile must be broadband. Otherwise, when facing radars of different bands, it is impossible to change the seeker to the appropriate band before going into battle."

"Let's think of a way. Anyway we have to ask our comrades who are working on radar for advice. Let's just throw it all in!" The Radar Research Institute is not willing to be outdone. Everyone wants to get their hands on good stuff.

"We fully support you!" the Air Force comrades took the responsibility.

For them, the advantage of this method is that the requirements for pre-war intelligence are reduced, and there is a way to deal with ambushed air defense positions. After all, no one can guarantee that they can fully understand the enemy's radar deployment before the war.

"It's a pity that this weapon has a limited range. Long-range aircraft can only carry it in the rear, and the aircraft at the front have limited air retention capabilities, otherwise the enemy's radar would not be able to turn on at all."

The comrades of the Air Force said with some regret, but they were already very satisfied. They said this out of greed. Under the conditions of the day, most of the long-range aircraft were patrol aircraft, early warning aircraft, etc., which could not rush to the front line during combat. The attack aircraft on the front line had limited time in the air and had to undertake other tasks.

Then they saw Gao Zhendong laughing.

There is a door!

"Comrade Zhendong, if you have any good ideas, please share them with us." The chief engineer of the Defense Work Committee said with a smile.

"That's exactly what I want to say next. Don't you have a modified MiG-15 unmanned target drone? Modify it and add an anti-radiation seeker. When in combat, just circle over the war zone. Even if it's shot down, it will distract the enemy's air defense firepower. If it's not shot down, just wait for the enemy's radar to turn on, and then..."

We don't have the conditions to develop very advanced applications of drones now, but there is still a slight possibility of developing a patrol anti-radiation drone with a preset program.

"Good!" The Air Force comrade slammed the table.

From the enemy's perspective, it's scary to think about it. This thing is not afraid of you hitting it. If you want to attack the radar, you have to turn it on. If you turn it on, it can find an opportunity. If the radar is not turned on, then the radar is useless.

Even if the combat efficiency is not high due to technical reasons, it can at least make the enemy feel fearful and affect their air defense efficiency, which is enough.

"We will contact the comrades who are working on the unmanned target aircraft and ask them to think about whether this method of combat is feasible." The comrades in the Air Force said excitedly that as long as the comrades who are working on the unmanned target aircraft assess that it is possible to achieve, then this thing can be developed first, regardless of whether it is effective or not. No new thing can be accomplished overnight.

As for the anti-radiation seeker, it was going to be developed anyway, and when the time comes it will be just a matter of transplanting it, so there is no need to think too much about it.

Gao Zhendong seemed to have remembered something: "If you decide to do it, please ask the comrades who are working on drones to come to me. I have some other ideas I want to discuss with them."

Do you have any other ideas? It seems that today's drone shooting is not about testing the no-escape zone, but mainly about giving you some new ideas, right?

"Tell us, tell us." The comrades from the Air Equipment Bureau couldn't help themselves.

Gao Zhendong smiled and shook his head: "The rest is just an idea now, I still need to sort it out."

This is not an excuse. Drones can do a lot of things, but now they can only do a few things. For example, it is impossible for our drone operators to fight like playing games. The technology cannot keep up, so he really needs to think about what to do.
