Chapter 2030: Research Su-27

A good aircraft, first of all, if it is a beautiful aircraft, among all the fighters, the smoothest and most beautiful is the Su-27. This kind of wing-body fusion fighter looks quite atmospheric.
This kind of aircraft is extremely beautiful from a distance, and when viewed from a close distance, it is even more shocking for it. In comparison, what is the F-15? The F-15 still has a conventional aerodynamic layout, and even the wing-body fusion is not used. The side wing of this aircraft is perfectly integrated into the fuselage. In other words, the entire fuselage is a perfect whole. Where is the fuselage, where is the wing, it is originally one piece, even if it is the fuselage, it is also a huge lifting body structure, this is simply too beautiful!
"What's this tail?" As an airplane designer, Pellehack certainly wanted to look from the front cabin, but when he swept something in the tail, he couldn't help but ask, this plane In the airplane, between the two engines, there is actually the tip of a backward cylinder, which is like the tail vertebra of an animal, which is quite strange!
"What do you think?" Chen Rui asked him, clearly testing him.
Pellehak frowned, thought about it seriously, and said, "This must be due to the need for pneumatic control."
Jiang was still old and spicy. Pellehak had studied airplanes for half a lifetime, and he still had this vision, and he found the key point all at once.
This is the need for aerodynamic design. This aerodynamic shape makes extensive use of side strips to pull the vortex, but the vortex airflow formed by the airflow through the body will be broken at the tail, which is disadvantageous. The existence of this tail cone makes The vortex airflow is attached to the tail cone, delaying its breaking speed, thereby improving the Su-27's flight ability.
Of course, there are other reasons. The two engines are far apart. Due to the ejection effect of the tail jet flow between the engines, there will be flight resistance. The impact of low-altitude flight is particularly serious.
If the two engines are separated by more than one meter like the F-14, they can also be separated. If the two engines are close together like the F-18, these factors can also be eliminated. This is the current engine layout, which is not far or near. , It happens to have this effect.
Therefore, the layout of the tail cone, the tip of the cone until the fusion of the jets of the two engines, greatly reduces the resistance of the flight and fills the low pressure area behind the fuselage.
"Of course, there are other benefits. The existence of this tail spine can avoid losing two engines at once, and you can also put things in it." Chen Rui continued.
Chen Rui’s observation angle is from the combat direction. This layout can separate the two engines. Once hit by the enemy’s missiles, one engine will be damaged, and the other will work normally. .
As for putting things in it, is that an umbrella?
Hearing the words of the deceleration umbrella, Chen Rui shook his head: "Mr. Pellehak, your imagination is too rich, can't it be a radar? If you put a radar here, even if the search distance is only 30 kilometers , You can also take care of your back hemisphere greatly, and you can even shoot the missiles on the front wing pylons directly to the rear to protect your back hemisphere."
Missile after fire? Hearing Chen Rui's description, Pellehak was also shocked. No one had ever imagined this!
In the oldest era, submarines can launch torpedoes not only in the front, but also in the back, but with the advancement of technology, the torpedoes fired later are cancelled because there is no means of guidance, and the submarine's sonar system is in the front. of.
The same is true for airplanes. Because the airplane’s radar is in front, it can only see the target in front of it, and it can only launch missiles forward. As for shooting backwards, it’s definitely a joke. In the sky, don’t the pilots turn by themselves. Come here, look for the enemy hiding behind?
This is just like the air brake of an airplane. Some people think that the air brake of an airplane is necessary, but it is not necessarily true. The pilot can directly use the entire fuselage as the air brake at a high angle of attack.
In addition to the lack of guidance, missiles fired backwards will also lose speed. Because the carrier is forward, the missile originally has forward speed. Now, if it suddenly moves backward, the speed will be lost. It’s very powerful, unless you launch forward first and then turn back, which probably requires thrust vector control capabilities.
It's all tasteless, but, I have to say, this is definitely an idea. If it can be done, then it will be quite dangerous to chase after the fighters that attack the other side. People may directly attack the fighters behind from the front!
"You laughed." At this moment, Pellehak suddenly reacted: "How can Xiong Guoren's technology integrate such a radar system in such a small place? If it is your radar, or our radar, it is still almost."
Pellehake's words made Chen Rui also smile, yes, Xiong Guo's electronic equipment is too backward.
Now that the plane is in our own hands, it is of course necessary to study it. At this time, Pellehak has also been on the front cabin, stepped on the ladder, and looked at the mechanical instruments in the cockpit. There was also a down-view display inside. No, it's just an increase in the HUD. It is conceivable how backward the electronic system of this fighter plane is.
"I bet that their radar will not use the most advanced antenna." Pellehak said.
He wanted to see it, but he didn't know if he could be allowed, so he said like this. After hearing what he said, Chen Rui smiled and asked the ground crew to open the nose of the machine. When the head was turned on, he saw Everyone was stunned at this huge radar.
Xiong Guoren is the best at violent aesthetics. This kind of radar looks extremely large and heavy. The inverted Casceloren antenna occupies the entire nose. From here, backwards, it is all electronic equipment. These electronic devices are densely flooded with the front compartment, which is dazzling.
"Xiong Guoren's electronic technology is still so backward." Pellehak said.
"Yes, their fighter plane is very advanced in appearance, but it is dragged down by the electronic equipment." At this time, Qin Guan was over and came over with gusto.
Just like the MiG 25, under the terrible triple the speed of sound, the inside of the body is full of stainless steel, and the Su-27, with its smooth and beautiful appearance, is actually a backward avionics. The plane was dragged down by this huge one-ton radar.
