Chapter 2030

A good plane, first of all, a beautiful plane. Among all the fighters, the most fluent and beautiful is the Su-27. This kind of wing body fusion fighter looks quite atmospheric.

From a distance, this kind of aircraft is incomparably beautiful. From a close look, I feel shocked by it. In contrast, what is the F-15? The F-15 is still a conventional aerodynamic layout, and even the wing body integration is not used. The side wing of this aircraft is perfectly integrated into the body, or the whole body is a perfect whole. You can't tell where the body is and where the wing is. It is an integral body. Even the body is a huge lifting body structure, It's so beautiful!

"What's the tail?" as an aircraft designer, pelehack certainly looks from the front cabin, but when he sweeps something at the tail, he can't help asking. The plane, between the two engines, actually has a backward cylinder tip, which is like an animal's tail vertebrae. It's quite strange!

"What do you think?" Chen Rui asked him, which was clearly testing him.

Pelehak frowned, thought carefully, and said, "this must be for pneumatic control."

Jiang is still old and spicy. Pelehack has studied planes for half his life. He still has this vision. He found the key at once.

This is the need of aerodynamic design. This aerodynamic shape uses a lot of edges to pull vortices, but the vortex system formed by the air flow through its body will break at the tail, which is harmful. The existence of this tail cone makes the vortex system air flow adhere to the tail cone, delays its breaking speed, and then improves the flight ability of Su 27.

Of course, there are other reasons. The two engines are far away from each other. Due to the ejection effect of tail jet flow, flight resistance will be generated between the engines, especially at low altitude.

If, like the F-14, the two engines are more than one meter apart, they can also be separated. If, like the F-18, the two engines are close together, these factors can also be eliminated. The current engine layout is not far or near, which happens to have this effect.

Therefore, the layout of the tail vertebrae, from the cone tip to the fusion of the jet streams of the two engines, greatly reduces the flight resistance and fills the low-pressure area behind the fuselage.

"Of course, there are other advantages. The existence of this caudal vertebra can avoid the loss of two engines at one time and put things in it," Chen Rui continued.

Chen Rui's observation is from the direction of operation. This layout can separate two engines. Once hit by an enemy missile, one engine will be damaged, and the other can work normally.

As for what's in it, is that a deceleration umbrella?

Hearing the words "deceleration parachute", Chen Rui shook his head: "Mr. pelehack, your imagination is not rich. Can't it be a radar? If you put a radar here, even if the search distance is only 30 kilometers, you can greatly take care of your rear hemisphere. Even, you can aim the missiles on the front wing pylon directly at the rear and launch them to protect your rear hemisphere."

After hearing Chen Rui's description, pelehak was also shocked, which has never been imagined!

In the oldest era, submarines can launch torpedoes not only in the front, but also in the back. However, with the progress of technology, the rear launched torpedoes are cancelled, because there is no guidance means, and the submarine sonar system is in the front.

The same is true of the aircraft. Because the radar of the aircraft is in front, it can only see the target in front of it and launch missiles forward. Shooting backward is definitely a joke. In the sky, won't the pilot turn around and find the enemy hiding behind?

This is like the speed brake of an aircraft. Some people think that the speed brake of an aircraft is necessary. In fact, it is not possible. The pilot can directly use the whole fuselage as the speed brake at a high angle of attack.

In addition to the lack of guidance, backward launched missiles will also lose speed, because the carrier aircraft is moving forward. The missile originally has forward speed. Now, if it suddenly moves backward, the speed will be lost seriously. Unless it is launched forward and then turned back, I'm afraid it needs thrust vector control capability.

It's all chicken ribs, but I have to say that this is definitely a creative idea. If it can be made, it will be quite dangerous to catch up with and attack each other's fighters in the future. People may directly attack the fighters behind from the front!

"You're kidding." at this time, pelehak suddenly responded: "how can bear people's technology integrate such a radar system in such a small place? If your radar or our radar, it's almost the same."

Pelehak's words made Chen Rui smile. Yes, Xiong Guo's electronic equipment is too backward.

Now that the plane is in the hands of its own side, of course, it needs to be studied. At this time, pelehak has also been in the front cabin, stepped on the ladder, looked at the mechanical instruments in the cockpit, there is not even a down view display in it, but just added a head up display. It can be imagined how backward the electronic system of this fighter is.

"I bet their radar won't use the most advanced antenna," pelehak said.

He wanted to see it, but he didn't know if he could be allowed, so he said like this. Hearing his words, Chen Rui smiled and asked the ground crew to turn on the nose. When he turned on the head, everyone was shocked to see the huge radar.

Xiong Guoren is best at the aesthetics of violence. This kind of radar looks incomparably huge and bulky. The inverted casseloren antenna occupies the whole nose. From here on, back to back, there are electronic devices. These electronic devices are densely filled with the front partition frame, which is dazzling.

"Xiong Guoren's electronic technology is still so backward," pelehak said.

"Yes, their fighter is very advanced in appearance, but it is dragged down by electronic equipment." at this time, Qin Guan has finished and came here with great interest.

Just like the MiG-25, under the terrible aura of three times the speed of sound, there are a lot of stainless steel inside the body, while the Su-27, with its smooth and beautiful appearance, is actually a backward avionics equipment. The whole aircraft is dragged down by this huge one ton radar.
