This is the first time that Mhammad has come to Shenyang.

At the beginning, due to geographical reasons, when the Soviet Union defeated the German fascists on the Western Front, and at the same time launched an offensive on the Eastern Front, the invincible little Japan found that under the blow of the polar bear of the Soviet Union, they had no power to fight back at all.

The Soviet Union liberated the three eastern provinces, and almost all of the Bingfeng went to the dam in Zhangjiakou, and Little Japan was defeated on all fronts.

After the end of the war, the three eastern provinces became close to the Soviet Union and became the first bases aided by the Soviet big brother, and they became the famous old industrial bases of the republic.

Automobiles, airplanes, and other key industrial products were first produced in the three eastern provinces.

As the big brother, Shen Fei has always been proud, and the country's various resources are prioritized, even the graduates of each class of aviation colleges and universities are selected by Shen Fei first, of course, his own children must be given priority.

However, Shen Fei did not hand in any satisfactory answers, and the only thing that could be taken out was the high-altitude and high-speed fighter of Jian-Ba.

At this time, Cheng Fei has begun to mass-produce the third-generation aircraft Jian-10, as the eldest son of the republic, Shen Fei's heart can be imagined, they all dream of having a third-generation aircraft to manufacture, but with Shen Fei's own ability, it is absolutely impossible.

You must know that when Shen Fei built a J-8-2, he was already using his strength to eat milk, hurriedly finalizing and equipping the troops, but as a result, the troops flew out of the big problem, and they didn't admit it, and the prevarication was the pilot's problem, until the leader in charge scolded the street, Shen Fei admitted his mistake, went back to find the fault, and improved it again.

And the J-8 is actually a double-engine version of the J-7, and they want to develop a new fighter, which is still the main air supremacy fighter of the twin-engine. That's just a dream.

Therefore, the most realistic thing is to introduce from abroad, introduce production line production, and master technology in production.

After the F-16 miscarried, Shen Fei was also relieved. Luckily, it wasn't introduced at the time! Otherwise, with the sanctions imposed by the Americans, Shen Fei would have to be self-reliant and overcome so many technical problems, and now, the big brother of the Soviet Union has shown a friendly posture again, and wants to export their main fighters to Huaxia, and also establish a production line, of course Shen Fei will be tempted!

What is West Flying? Just a little brother. If you want to create a tomcat to compete with yourself, don't dream!

The Su-27 had a lot of technical problems before, but the Sukhoi Design Bureau, which had first-class aircraft designers, had already improved those technical problems, and at the critical time of winning the Huaxia contract, Sukhoi flew a new aircraft. A flight show was performed to demonstrate the aircraft's maneuverability. Strive to get orders from Huaxia!

Shen Fei couldn't wait to become Shen Huo Yi as soon as possible.

A large group of leaders from the central government came to Shen Fei, including the friendly president of Pakistan.

Deng Gong did not follow, and he was accompanied by the main leaders of the military, including the Minister of Defense and the Air Force Commander.

All the way. Mhammad was still curious, and when he saw the new plane of the Soviets, the first thing he did was to ask the ground crew to turn on the nose of the plane and see what the radar inside looked like.

Mhammad, of course, knows the main problems of the Su-27. It is because of backward electronic technology that the radar is too heavy, and the entire nose of the Su-27, except for the pilot's cockpit, is filled with electronic equipment, and the heat of the radar is almost dissipated into the cockpit, which is called an uncomfortable. The overweight radar led to the waste of the original trim performance of the Su-27, and in order to re-trim, even the matter of drilling holes in the girder was done, which is how hypochondria came from.

Therefore, if the Su-27 wants to change the original defects, it must improve the electronics and improve the radar, but the Soviets have been on the road of electron tubes for so many years, and now even if they catch up, they will not get the most complex airborne radar in just a few years, right? On the contrary, the Soviets, Marshal Ogarkov, the Minister of Defense, were complete reformers, believing that future wars would be the world of precision-guided weapons, and that it was necessary to attach importance to electronic technology.

Shen Fei wants to fully replace Huaxia's electronic equipment, especially radar, after it is introduced, which is not so simple. Thanks to the crossing of Mhammad, thanks to the diligence of Bai Xue and others, Huaxia has now surpassed the Soviet Union in terms of airborne radar. However, the radar is not directly installed, the Su-27 has been redesigned, and the front has been replaced with a radar that is half lighter, and the center of gravity of the entire fuselage has shifted again.

On the way here, Mhammad thought a lot, but when he came to Shen Fei and saw the Su-27 that was temporarily displayed on a section of the runway, he was still stunned for a moment. Got the Su-35 out so quickly?

The Su-27 is a single-swept wing fighter with a full-moving tail, and now, at the front end of the wing, where the large side strip, a pair of canard wings has been added, becoming a three-wing fighter!

Three-wing surface! It seems that Sukhoi is the only one in the world who does this, and the original intention of doing this is to level the nose.

The nose was too heavy, resulting in this aircraft that was originally designed to be statically unstable, and it completely became a statically stable aircraft, and its maneuverability was greatly affected, and Sukhoi jumped back and forth between weight reduction and enhanced fuselage structure for a long time after the birth of the Su-27, but it still could not avoid the tragedy of the Su-27 disintegrating in use.

Sukhoi is also doing its best, while the Su-27 is in service, it is constantly improving, and there are successively T-10S, T-10M, T-10K, T-10U, T-10IB five main line verification and prototype series, the total number of which has reached dozens.

And the T-10K, a product of this era, in order to counterweight the nose, Sukhoi came up with the idea of adding canard wings in front of the fuselage, and the lift provided by canard wings can be leveled to the fuselage!

At the same time, the canard wing also greatly moves the aerodynamic center forward, forming a static and unstable state, which enhances the pitch control ability of the aircraft. In the past, when the Su-27 fighter decelerates from supersonic speed to subsonic speed in a large overload circle, the violent movement of the aerodynamic center will cause the aircraft to automatically ascend, so as to limit the maximum overload in the transonic region, so as to avoid a catastrophic situation of loss of control under a large overload, which is also a reason why the Su-27 has a small overload at transonic speed.

And now the addition of canard wings, which gives the aircraft a strong ability to control its head down, completely overcomes this obstacle. With the addition of canard wings, the flat tail has reduced the burden on pitch control, and the flat tail can finally perform differential, that is, asymmetrical deflection on both sides, and improve the roll performance of the Su-27.

And Sukhoi is very good at the study of the three-wing surface, and it already has engineering practicality, that is, the Su-27K, that is, the carrier-based aircraft Su-33, but to improve the take-off capability.

The plane in front of him is definitely not the Su-33, the Su-33 is in order to get on the ship, but the fuselage is strengthened to withstand the huge impact of take-off and landing, and the result is heavier, and it is equipped with a larger thrust engine.

Moreover, the Su-33 deliberately shortened the tail vertebrae in order not to hit the ground when taking off and landing, and the aircraft in front of him, the first feature is the three-wing surface, and the second feature is the tail vertebrae between the two engines, this tail vertebra seems to be larger and longer, is there something strange in it?

Seeing that Mhammad stopped at this tail vertebrae, the Soviet technical experts on the side proudly introduced it.

A series of fluent Russian, in fact, Mhammad can understand directly, but the translator on the side still casually followed the translation, but the translation became Chinese.

They were mainly here to introduce the Chinese military, and Mhammad was just an additional guest, after all, it was impossible for the Soviets to sell Su-27 fighters to Pakistan.

"Inside this tail vertebrae, there is our newly developed rear-view radar!" The words of the Soviet expert were full of pride: "With this rear-view radar, our pilots can not only observe the situation in the front hemisphere, but also maintain a high degree of vigilance for the air situation in the rear hemisphere. ”

The words of the Soviet experts immediately made the senior officials of the Air Force present interested, and the radar could be added later? Missiles specifically against aircraft behind? Looks like it's very advanced, huh?

Mhammad couldn't help but want to laugh in his heart, he's a cheat again, the radar on the tail? The tail vertebrae are so large, the radar antenna on the tail vertebrae will certainly not be as large as the front, the search range is limited, and the performance of this radar is certainly limited at the technical level of the Soviets, and in actual combat, it has no effect, as for over-the-shoulder shooting, it is an ideal situation. When the aircraft launches the missile, it is necessary to accelerate as much as possible, so that when the missile is launched, it can obtain an additional cumulative speed and increase the range of the missile, and now, when it is launched directly backwards, the range will be greatly reduced, and the over-the-shoulder shooting, the missile needs to be burned by the rocket engine and has gained a lot of speed before it can turn around, because the rudder efficiency of the missile is directly related to the speed, and at low speed, the rudder efficiency is very low, and it can't turn this corner at all. Unless thrust vectoring is used. By the time they turn in a big circle, the kinetic energy of the missile has been almost consumed, and this whimsical way can only be chicken ribs, which is far less advantageous than the carrier aircraft maneuvering to get rid of it and then occupy the launch position.

However, the nozzles of the two engines on either side of the tail vertebrae are a little strange.

"This is our latest engine, the tail nozzle can be steered, this fighter is named Su-27M in our country, but soon, it will have a new number, that is, Su-35!" Soviet engineers said. (To be continued......)
