From now on, Qin Guan made many arrangements to dig holes for the eagle country, because Qin Guan knew that in the future, the eagle country would be its biggest enemy. After all, the eagle country would dominate when the bear country disintegrated, and the rise of the Han country would be regarded as a thorn in the eye by the eagle people. Therefore, they must contain it, and even the containment will come faster, because now, The state of Han has developed quite strong.

Qin Guan is not a strategist. He just has the ability to predict. Now he starts to layout and decorate in the back garden of the eagle people. For example, in the butterfly country, Qin Guan has already begun to decorate. Now it's the turn of the lazhou oil country. When the eagle people open their eyes, they find that their back garden is completely disordered, I don't know how it will feel.

When Qin Guan thought of this, he felt that he could laugh from his heart. Will the event of the galaxy happen in the future? Of course not. After that, our navy will check the eagle people's cargo ships. We must take revenge and take those revenge!

With this idea, Qin Guan came to the land of abundance. According to the agreement, the guests from the petroleum country of lazhou will also come here first.

When Qin Guan arrived, he entered factory 1132 and was immediately attracted by a big guy.

This is a heavy fighter, which has never produced such a big guy in factory 1132. This factory used to produce single engine fighters, J-7, j-14 and J-10. Now, the fighter in front of him is so avant-garde and bold that Qin Guan feels bright in front of his eyes and blurts out: "black ribbon!"

Hearing Qin Guan's words, old song couldn't touch his head: "President Qin, our plane hasn't been sprayed with stealth coating."

Mr. Qin called the plane black ribbon, which surprised Mr. Song. He looked at his plane. Its nose was diamond shaped, followed by duck wings, and the rear main wing. The fuselage gradually widened, and the center of the aircraft belly was flat. After opening, there was a weapon cabin inside. The double vertical tails tilted outward to reduce the radar reflection area, The nozzles of the two engines shone silver.

This is their first stealth heavy air fighter. After several years of research and development, it has finally begun to enter the manufacturing of prototypes. This is much slower than that of Lao Lu.

After all, their project was improved on the basis of J-11. Moreover, they had the shape model provided by President Qin for a long time. Therefore, their R & D progress was rapid. On our side, it was not just the double engine amplification of J-10 fighter, but a complete innovation. It took two years to touch the aerodynamic layout and one or two years to design. Fortunately, over the years, R & D funds have always been in place. Abundant funds have made their R & D progress rapidly. Now, it has finally reached the stage of prototype.

This is a prototype, which is still in the final assembly. It is expected that it will take a few months to leave the factory for the first flight. Now, Lao Lu is estimated to have carried weapons for test flight. Therefore, they think their project can finally win the bidding. However, they will never know that although their own research and development is more backward, they are completely the latecomers, Our performance will be more advanced.

These are two different directions. They use the variable swept wing, which belongs to the technology of the second generation aircraft. Even if it is made of advanced titanium alloy, it must have the problems of weight gain and complex operation. Our own side uses a duck layout, which completely uses the eddy current to provide positive lift for instant rise. In modern air combat, The instant pointing of the nose is the most important. At this point, the duck layout is perfectly suitable!

Therefore, old song was very satisfied with his fighter. Now, he looked at the aircraft being assembled. The assembled fuselage and wings were shining with yellow primer. How could they be called black ribbons?

Qin Guan smiled helplessly. Yes, when he saw this aircraft, he was too excited. He shouldn't call this aircraft black ribbon. There is no black skin yet. However, Qin Guan's excitement also has a reason. After all, no military fan can refuse the temptation of black ribbon. This is the most advanced fighter in Han Dynasty!

"The final assembly is now under way, and the avionics system in the cockpit is being installed. It is expected to take several months. When the first flight is made, we also hope President Qin can be present."

The original intention was to surprise president Qin. He called President Qin on his first flight. Who would have thought that President Qin, who was busy, would come to inspect now. Therefore, old song reported to Qin Guan that he must come and join in at that time.

"That's for sure. I just don't know how to choose Chen Rui," Qin Guan said.

Chen Rui is still testing the fourth generation aircraft with variable swept wings. Chen Rui is there almost every day and is reluctant to leave. Now, the stealth aircraft here is about to be built. Will Chen Rui come to test fly?

Qin Guan doesn't know. It depends on Chen Rui's meaning. I don't know which one Chen Rui likes. However, after the initial test flight, Chen Rui will go to the test flight academy for the test flight of subsequent subjects. At that time, Chen Rui will certainly fly all the time. One in the morning and one in the afternoon. Chen Rui can't be refreshing.

The development of the fourth generation aircraft requires huge capital investment. Even Eagle country cannot support the research and development of multiple projects. Therefore, the stealth aircraft project of Eagle country navy was later cut off, leaving only the F22 of the air force and the F35 of the Navy after waiting for so many years

However, now the Han country is definitely rich and powerful. Qin Guan has made great efforts in the research and development of stealth aircraft. He needs funds and equipment. Therefore, two stealth aircraft have been invested in research and development at the same time.

Now, both sides are competing. How to choose in the future is really a headache.

From the point of view of inheritance, the variable swept wing is obviously the same origin. Moreover, the supersonic cruise has been achieved without the power of the engine. However, from the technical point of view and the later generations' feelings, the black ribbon is more attractive. Qin Guan now feels that some suck is difficult.

"Tell me, Mr. Song, what is the difference between this aircraft and the other one except the wing structure?" Qin Guan asked Mr. Song.

Now, who you want to choose, of course, depends on the performance. When you first saw Lu Lao's plane, Qin Guan was also amazed. The display equipment in the cockpit is still touch screen. Of course, the domestic supporting manufacturers are the same, and both sides can integrate these equipment.
