Chapter 2091: MiG 31

The MiG 25 is designed according to this kind of thinking, and this upgraded model takes this idea to the extreme.
Speaking of MiG 25, one aspect that makes people sigh is stainless steel. In order to reach the speed of Mach 3, Xiong Guoren uses simple stainless steel to solve it. However, on MiG 31, the content of titanium alloy has been greatly increased. Now, it is no longer a pure stainless steel fighter.
There are many changes. The previous turbojet engine has been replaced by a turbofan engine. Because of the windward area and other reasons, the turbojet engine has no external duct and is naturally suitable for high altitude and high speed. However, its fuel consumption rate is very high. Therefore, on the MiG 31, a new generation of 150 kN D-30F6 afterburner turbofan engine is installed. This thrust is quite powerful. By comparison, the afterburner thrust of the MiG 25 is only 109 thousand. It's just a cow.
At the same time, the single maximum thrust of this engine is 93.1 kilonewtons, that is to say, the power of the MiG 25 is almost the same without the afterburner.
what does this mean?
It can directly perform supersonic cruise without afterburner! This is a huge change. The MiG 25 must be powered on to exceed the speed of sound to reach Mach 3. Even if it carries 19 tons of fuel, the fuel will be consumed at an alarming rate when it is powered on. .
However, the MiG 31 does not need it. When needed, it can fly at supersonic speed only by relying on the maximum military thrust. This is called supersonic cruise, which can last for a long time. F22 is proud of its performance standard. It has already been implemented on the MiG 31.
Of course, to fly faster, you still need to open the afterburner. Although the engine thrust of the MiG 31 is greater, due to the turbofan engine, its maximum speed has been reduced from Mach 3 to Mach 2.8.
In addition to the replacement of the engine, another major change is its radar system. Compared with the MiG 25’s apprentice, it has more powerful power, but most of it becomes a heat radar. Its biggest feature is the introduction of Phased array radar!
Xiong Guoren bypassed the plate gap radar and directly developed the airborne phased array radar. It started with the MiG 31. Of course, because of the backward technology, all they can achieve is only the passive phased array radar using ferrite phase shifters. Even so, it has powerful functions when used on MiG 31, and finally you don't need to be timid in front of the Tomcat!
It also has a radar system that has a search range of 200 kilometers, tracks ten targets at the same time, and can attack four targets at the same time. This is a huge improvement!
As for the higher weight and larger volume, these are acceptable.
In addition to the powerful radar, it also has the R33 missile with a range of more than one hundred kilometers. This missile is called the Phoenix by military fans because it is similar to the Phoenix. The cooperation of these programs makes the MiG 31 finally It has become the most suitable fighter for the Homeland Air Defense!
In order to operate this system, the MiG 31 interceptor had to increase the position of the second crew cabin, where the radar officer’s place was. Because of their cockpit display system problems, the cockpit was deliberately dimmed.
If you analyze it carefully, you can get a conclusion that this set of equipment is simply a set of S300 mini version that can fly.
Their MiG 31 is to squeeze out the Su-27 market. After all, the Su-27 is also used by the Homeland Defense Air Force. The Mikoyan Design Bureau and the Sukhoi Design Bureau have to constantly compete in these aspects.
Now they showed the MiG 31 to Qin to watch. On the one hand, because this fighter has been equipped with troops for several years, the West has also continuously collected information on this aircraft through reconnaissance satellites, and many secrets have begun to leak. , I also want to tell Qin Guan that you should take a look at our Mikoyan Design Bureau. We are the representative of the future. The performance of our aircraft is the most advanced.
Look at the Sukhoi Design Bureau, is there such a thing?
Qin Guan looked at the MiG 31 in front of him, naturally knowing the huge effect of this kind of fighter on the bear country, but only for the bear country, besides the bear country, who else needs such a big guy?
In the small countries of Europa, a light aircraft such as the F-16 flew to the border in a short time. There is no need at all. As for Han, there is already a heavy J-11 fighter jet, so there is no such demand. .
Their big guys should be shown to Sukhoi, what's the point of showing them to yourself?
Well, if one or two are imported for high-altitude atmospheric research, it can also be used to train astronauts. Even, you can take a tourist to experience what it feels like at high altitude and develop new tourism projects. There must be many People will like it.
However, importing in large quantities is absolutely unnecessary, and it is estimated that people will not sell it, right?
In this case, it's better to find the fault.
"This kind of aircraft is also suitable for a big country like Xiong Country." Qin Guan said: "As a long-range interceptor, it is still very competent, but it is said that it is very heavy and consumes a lot of power. Compared with Su-27’s radar, I’m afraid it’s on par with Su-27’s radar?
If this kind of thing is in the West, the performance will definitely be more advanced, but now in the bear country, the biggest problem is the poor backward electronic technology.
This kind of passive phased array can be regarded as a phased array at any rate. After adopting this system, the radar antenna does not move. It mainly scans by changing the phase of the radar beam. The scanning speed is fast, the refresh is fast, and a plane can be divided into several In part, this will have multi-target strike capabilities.
However, the later processing system limits it! Although it is very powerful and refreshes quickly, it does not have an advanced processing system, resulting in performance defects, and the anti-jamming capability of this radar is not good.
Compared with Xiong Guo, this technology has crossed the age, but compared with other technologies of this era, it shows that it is out of date.
You know, the current Han country has begun to develop an active phased array. Of course, this is the most powerful airborne radar technology. Qin Guan will never give it to the Xiong Guoren, and there is no door.
"Of course, what I said like this may make many people feel dissatisfied. We can compare the MiG 31 with the Su-27 equipped with avionics to see who finds each other first, and even export it to Look at the MiG-29 from the Date Palm Country."
Qin Guan also participated in the MiG 29 exported to the date palm country, because the avionics in it was updated by Han. They may not know the advanced Su-27, but they must know that the MiG was modified by Han. How powerful is 29's avionics?
