Super Weapon Swap System

MIG 25 is designed according to this idea, and this upgraded version gives full play to this idea.

Speaking of MiG-25, one aspect that makes people sigh is stainless steel. In order to achieve Mach 3 speed, Xiong Guoren used simple stainless steel to solve it. However, on MiG-31, the content of titanium alloy has greatly increased, and it is no longer a pure stainless steel fighter.

There are many changes. The previous turbojet engine was replaced by a turbofan engine. Due to the windward area and other reasons, the turbojet engine has no external culvert and is naturally suitable for high-altitude and high-speed. However, its fuel consumption rate is very high. Therefore, a new generation of 150kn d-30f6 afterburner turbofan engine was installed on the MIG 31. This thrust is quite powerful. Compare it, The afterburner thrust of MIG 25 is only 109 kn.

At the same time, the maximum thrust of this engine is 93.1 kn, that is, it is almost the same as the power of MIG 25 without opening afterburner.

What does that mean?

It can conduct supersonic cruise directly without afterburner! This is a huge change. MIG 25 must be powered on to exceed the speed of sound and soar to Mach 3. Even if it carries 19 tons of fuel, the fuel will be consumed at an amazing speed.

However, the MIG 31 is not needed. When needed, it can fly at supersonic speed only with the maximum military thrust. This is called supersonic cruise. It can last for a long time. The performance standard that F22 is proud of has been realized on the MIG 31 for a long time.

Of course, to fly faster, you still need to turn on afterburner. Although the engine thrust of MIG 31 is greater, due to the turbofan engine, its maximum speed is reduced from more than Mach 3 to Mach 2.8.

In addition to the replacement of the engine, another major change is its radar system. Compared with the disciples of MIG 25, it has strong power, but most of it has become thermal radar. Its biggest feature is the introduction of phased array radar!

Xiong Guoren bypassed the flat slot radar and directly developed the airborne phased array radar, which began with MiG-31. Of course, because of the backward technology, they can only realize the passive phased array radar using ferrite phase shifter. Even so, when used on MiG-31, they also have powerful functions, and finally don't have to be timid in front of male cats!

It also has a radar system with a search distance of 200 kilometers, tracking ten targets at the same time, and can attack four targets at the same time. This is a great progress!

As for the high point of weight and larger volume, these are acceptable.

In addition to the powerful radar, it also has an R33 missile with a range of more than 100 kilometers. Because this missile is similar to the undead bird, it is called the undead bird sky by military fans. The cooperation of these schemes makes MIG 31 finally become the most suitable fighter for the homeland defense air force!

In order to operate this system, the MiG-31 interceptor had to add the position of the second crew compartment, which is the place of the radar officer. Because of the problem of their cockpit display system, it deliberately darkened the cockpit.

If you analyze it carefully, you can get a conclusion that this set of equipment is simply a flying S300 mini version.

Their MiG-31 is to squeeze out the market of Su-27. After all, Su-27 is also used by the homeland defense air force. Mgyang Design Bureau and Sukhoi design bureau should constantly compete in these aspects.

Now, they show the MiG-31 to Qin. On the one hand, this kind of fighter has been equipped with the army for several years, and the West continues to collect information about this kind of aircraft through reconnaissance satellites. Many secrets are beginning to leak. On the other hand, they also want to tell Qin Guan that you'd better take a look at our Migao Yang Design Bureau. We represent the future, our aircraft, Performance is state-of-the-art.

Look at the Sukhoi Design Bureau. Is there such a thing?

Qin Guan looked at the MiG-31 in front of him. Naturally, he knew the great role of this fighter plane in the bear country. However, just for the bear country, who needs this big guy besides the bear country?

For those small countries in Europe, it is not necessary for light aircraft such as the F-16 to fly to the border in a short time. As for the Han country, there is no such demand for heavy J-11 fighters.

Their big guy should show Sukhoi and show himself these. What's the use?

Well, if you import one or two aircraft for high-altitude atmospheric research and training astronauts, it's good. Even, you can bring a tourist to experience the feeling of high-altitude and develop new tourism projects. Many people will like it.

However, it is absolutely unnecessary to import in large quantities, and it is estimated that people will not sell it?

In that case, let's just find fault.

"This kind of aircraft is suitable for a big country like Xiong state." Qin Guan said, "it's still very competent to be a long-range interceptor. However, it's said that it's heavy and consumes a lot of power. I'm afraid it's comparable to Su 27's radar?"

If this kind of thing is in the west, its performance will certainly be more advanced, but now in bear country, the biggest problem is poor and backward electronic technology.

This passive phased array is, at least, a phased array. 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 and the refresh is fast. Moreover, a plane can be divided into several parts, so it has the ability of multi-target attack.

However, the post-processing system limits it! Although it has great power and fast refresh, it has no advanced processing system, which leads to performance defects. Moreover, the anti-jamming ability of this radar is not good.

Compared with Xiong Guo, this technology has crossed the era, but compared with other technologies of this era, it shows that it is out of date.

You know, the Han state has begun to develop active phased array. Of course, this is the most powerful airborne radar technology. Qin Guan will never give it to Xiong people. There is no door.

"Of course, what I said may make a lot of people dissatisfied. We can compare MIG 31 with Su 27, who is equipped with avionics, to see who found the other party first, and even MIG 29, which is exported to date country."

Qin Guan also participated in the MiG-29 exported to yezao country, because the avionics inside are updated by the Han country. They may not know the advanced Su-27, but they must know how powerful the avionics of the modified MiG-29 by the Han country?
