Chapter 557 The only option for interception
Seeing that everyone has unanimous opinions on this, the leader of the Air Force is still very proud. Comrade Zhendong, you are very skilled in technology, but I am better at implementing specific affairs. Hahaha.
Seeing this, the leaders of the National Defense Working Committee secretly laughed inwardly. The Air Force was so dedicated, so it was obvious that they had completely fallen into Gao Zhendong’s trap and could not get out.
The main reason why this guy chose the G-5 as the foundation of the multi-purpose fighter is definitely for the sake of technology, but the benefits of not changing the original production system as much as possible and reducing resistance from relevant parties must also be taken into consideration.
Well, I am getting more and more mature.
The leader of the Defense Working Committee timely brought the topic to the following content: "Comrade Zhendong, what about the rest of the third level and the third type?"
Gao Zhendong nodded: "Actually, the second type, just now As mentioned, it is a high-altitude, high-speed interceptor aircraft with a certain range. This interceptor aircraft mainly operates under the guidance of the ground-to-air radar system. It does not need a very good radar. In other words, it is not a big problem if it does not have a very good radar. The top speed is Mach 2, the practical ceiling can be between 19,000 and 20,000 meters, and the bomb load is about 1 ton. It is enough to be able to carry missile weapons for combat, but it must have heavy load points.”
Air Force Wrinkle. Frowning: "Interceptor, but it only has a ceiling of 20,000 meters? Give up above 20,000 meters?"
Gao Zhendong smiled: "The enemy can't go either, the practical ceiling of most tactical aircraft is Below 20,000 meters, in fact, the root cause is not the engine, but the altitude above 20,000 meters. Due to the structure and composition of the atmosphere, if you want to fly higher, you must either use some special technology or fly a brick with great strength. In short, the cost is high. It’s very big. This means that we can’t go there, and neither can the enemy.”
For example, the U-2 strives to increase lift but doesn’t have any mobility, the SR-71 has a ramjet engine and aerodynamics that can’t turn. The appearance also leaks oil.
As for the MiG-25, which was developed in the early 1960s and entered service in 1969, this product is really well designed.
At first glance, it looks like a pure force, but in fact the design is very clever. The central lifting body ensures lift, the dual vertical tails ensure controllability, and the oversized air inlet and engine ensure thrust. As for that The stainless steel body is designed to solve pneumatic heating at a lower cost.
Think about what other aircraft’s aerodynamic solutions are particularly similar to it?
Hey, that’s right, Citigroup’s F-15! This product was awarded the bid by McDonnell Douglas in 1969. It first flew in 1972 and entered service in 1974. Then it became known as the "Hangar Queen" due to engine problems.
Lao Maozi especially likes this plane because it needs to carry 0.25 tons of alcohol on each flight! It's not burned, it's used to cool down the air intake.
Even better is that this 0.25 tons of alcohol does not have to be used up every time! Ура!
And what Gao Zhendong also knew was that none of the "Double 3" high-altitude and high-speed penetration bombers were in service! There are quite a few "double 2" ones, but that's much easier to deal with.
But comrades in the Air Force still have questions about this.
“But now there is a U-2 with a practical ceiling of 24,000 meters, and there may be higher ones in the future.”
Gao Zhendong nodded: “Yes, this is my special request. , the reason why this aircraft must have heavy load points is that there are not many such aircraft, and it is not cost-effective to build a special aircraft for them, so my idea is to build a missile for them! Even if it can only carry heavy missiles! One aircraft and two aircrafts working together can pose a sufficient threat to such targets.”
In fact, the MiG-25 is equipped with a missile similar to the R-40, but it is very large, about 6 meters long and weighs 0.5 tons. Although it is so big, its range, speed, and maneuverability are relatively ugly due to technical reasons.
It may not look ugly, but the one that has achieved results is a very advanced-sounding aircraft, the F/A-18.
“Missiles?” Gao Zhendong’s turn made everyone a little confused. We are talking about airplanes here.
But after the initial confusion passed, I felt that this seemed to be a solution. Yes, if the plane cannot go up, just shoot the missile up.
But the key to this lies in the missile.
"What are your thoughts on this missile?" Let's first look at the settings of the missile's performance.
“The missile is 4 to 5 meters long, weighs about 400 kilograms, has a range of 50 to 80 kilometers, a combat altitude of no less than 35,000 meters, and a speed of Mach 3 to 5. It uses radio command guidance in the front stage and infrared guidance in the final stage. "
This parameter is basically based on the upper and lower limits of R-40 and the size of the AIM-54 Phoenix. There is no doubt that in this era, that is shocking. How is it possible?
"Comrade Zhendong, based on existing technology, it is difficult for missiles to achieve this performance, especially the range." Some technicians raised objections.
Gao Zhendong shook his head: "There is still hope for a missile of this weight to reach this range with its own power. The biggest problem is still in the guidance. This is why I chose radio command guidance and infrared terminals. The reason for guidance.”
Moreover, I know that there is no need to worry about the range of the missile itself, but I can only think about this in my mind.
"Radio command? Why not use semi-active irradiation?" This person obviously has considerable research on weapons. "Because it is cheap, and for high altitude and high speed, given the current capabilities, it may still be necessary to use the nose of the aircraft to take air in. The radar performance will not be very good, and the illumination power at such a distance is insufficient."
As for his words, everyone understands that his interceptor aircraft is basically better than the MiG-21 according to current requirements. This conclusion that the radar is not very good comes from this. .
"Since the radar is not very good, how can we ensure that the interceptor can detect the target?" This is what you said yourself, the radar is not good.
"Based on several judgments and conditions, first, the radar echo of this type of target is generally very strong. An aircraft that can fly at such a high altitude cannot be small, and its detection distance is relatively long. Although it may not be able to illuminate continuously, it is In terms of radar detection and positioning with poor performance, there is still a certain basis."
Well, it makes sense, but it is not safe.
"Second, I have some ideas that can solve the problem of the nose radar to a certain extent without making too many changes and ensuring the flight performance as much as possible. Uh... that is... the aircraft will be very Ugly! "
General Engineer Gao, you just stand and talk without your back hurting. We are still thinking about whether we can solve the problem. Are you thinking about whether you are ugly or not?"
"Third, a potential capability of radio command guidance is that the missile carrier aircraft does not necessarily issue commands by itself. The command can come from other radars or aircraft, such as the aforementioned early warning command aircraft! Or, by Other radar stations or aircraft will send the enemy aircraft's position to the missile carrier aircraft in front, and then the transmitter will calculate it before sending instructions to the missile. This method is very troublesome, and it cannot deal with high-mobility targets in the final stage, but it can be used as a front-end missile carrier. Mid-stage guidance is still possible. ”
Hiss~~~~~~
Such a complicated guidance method surprised everyone.
"So, the aircraft itself becomes a missile. It is guided by an early warning aircraft or radar station to reach the launch position, then launches a missile, and the rest is nothing? "
Gao Zhendong smiled: "To a certain extent, it is true."
The chief engineer of the National Defense Work Committee frowned: "In this way, the fire control computer of the aircraft will be affected. , as well as the communication between the command aircraft and the carrier aircraft, and between the aircraft and the missile, the requirements are very high.”
Gao Zhendong nodded and said nothing.
Although he didn't say anything, the National Defense Work Committee and the Air Force immediately understood that his confidence came from here!
The person who put forward this suggestion was a comrade who was very knowledgeable in computers, communications, and radar signal processing, and he had achieved fruitful results, leaving even the old guys far behind!
Even the National Defense Working Committee knows that he has confidence in the physical range of missiles. The best solid propellants for tactical missiles now come from him! Even the liquid propellant of ballistic missiles has something to do with him.
Seeing that they were deep in thought, Gao Zhendong told another discouraging but extremely true fact.
"Actually, even without this missile, the best interceptor aircraft we may have now is only the MiG-21, right?"
Comrades from the National Defense Work Committee and the Air Force were dumbfounded when they heard this.
Hey, comrade, you are so unkind, you are talking nonsense!
"Uh...yes, yes, old X, I think Comrade Zhendong is right about using MiG-21 for interception missions. In a short time, there will be nothing else. This matter In fact, there is no doubt. It is just a matter of whether this missile can be produced and whether it can further improve our interception capabilities." The comrades of the Air Force looked at the National Defense Work Committee.
Everyone reacted. They were all dazzled by the new and powerful ability described by Gao Zhendong. They completely forgot that there was actually not much discussion about the interceptor aircraft. Apart from the MiG-21, what else is there?
"Haha, that's right. I'm impressed."
Having said that, what people in both units actually think about is that they still really want this missile!
A comrade in the Air Force had a flash of inspiration: "Chief Engineer Gao, why don't you recommend using the MiG-21 to make improvements similar to the Z-6 to the G-5 combat type? In this way, Can we not only ensure the interception performance, but also get a good radar?”
Hey, comrade, you can do it. You have a long-term vision and the road is widened.
Gao Zhendong nodded and shook his head: "Yes, yes, it is no problem as a long-term development plan. But the G-5 is based on the hard improvement work already done by the Porcelain Flying Factory. Only by further improvement can it be so promising. , but it still takes time to implement it. And the MiG-21 will not be able to carry out such a set of actions in a short time. Based on our foundation, it is estimated that it will take 6 to 8 years. In terms of time, it is too late.”
Too late? Many people are confused. Why is it too late? This comrade is good at everything, but he is too radical.
The leaders of the National Defense Working Committee and the Air Force looked at each other with gleaming eyes. Comrade, your thoughts are very dangerous. We like them!
However, we cannot elaborate on this. The leader of the National Defense Working Committee quickly changed the subject: "It is getting late today. We will adjourn the meeting and meet again tomorrow!"
