Super Weapon Swap System

Up to now, none of the planes in the Han Dynasty have been independently developed, and the jian-8 is not counted. The j-9 has died prematurely, and the J-10 project has just begun.

The technicians of the Han Dynasty, who do not have much self-confidence, want to refit the J-7 to the same fighting ability as the F-16, which is simply Arabian Nights.

Only Qin Guan knows that this is not difficult at all. The key is the double delta wing.

The MiG-21 is only a flash in the pan in Xiong's equipment. On the contrary, Han has played this fighter perfectly. When it is improved to the level of J-7 e, it is simply the best.

Unfortunately, twenty years later, this kind of fighter with air intake nose can no longer gain too much advantage in air combat, so it is doomed to be eliminated.

But now it's different. Now, before the 1980s, the over the horizon air combat in this era has not become the mainstream. Therefore, if the J-7 e is launched now, it will definitely usher in a small peak of export.

Among them, the main is the improvement of aerodynamics. The triangular airfoil wing is triangular as a whole, while the double triangular airfoil wing is like two triangles, and the swept angles of the inner and outer sections of the leading edge of the wing are different.

The double delta airfoil has better aerodynamic characteristics at high angle of attack than the triangular airfoil, which can shorten the takeoff and landing distance and increase maneuverability. The triangular wing has large subsonic resistance, while the double delta wing achieves a better balance between supersonic and subsonic.

The double delta wing actually reduces the sweep angle at the outer section of the wing, partially alleviating the problem of poor low-speed performance caused by the large sweep angle of the delta wing. After the J-7E changes to the double delta wing, the wing area and span are increased, and the lift is significantly improved. Therefore, there are even extreme statements. In fact, the upper strip wing can also be regarded as a double delta wing with super large inner sweep angle, The main function is to control the vortex at high angle of attack, improve the vortex lift and improve the lateral stability.

In addition to the double delta wing, the leading-edge maneuverable flap also makes a great contribution to the improvement of mobility. Therefore, the mobility of the ultimate improved version of the J-7 has been greatly improved, and it's no problem to play close combat with the F-16.

Qin Guan knows, but Tu Lao doesn't know. So now Qin Guan has put forward so many ideas that Tu Lao has backed down in his heart. However, it has greatly attracted the attention of the people of yezao.

"Really? If we can meet this standard, we can order a batch!" abid made up his mind immediately.

The people of yezao have great reservations about the super-7 fighter, but they are very interested in the improvement of the J-7. After all, this fighter is very similar to the MiG-21. After the improvement, the performance has been greatly improved, and the price will not be too high, which fully meets the needs of yezao!

"OK, but I hope you can pay a part of the deposit in advance, because our J-7 improvement is a self-developed project. We can't go on without funds." Qin Guan said: "of course, on the other hand, if our improvement can't meet your requirements, we can return the deposit completely."

Use your money first. If the performance is unqualified, you can return it. This fully shows Qin Guan's confidence. There is no reason for the jujube country not to agree to such conditions.

Out of his trust in Qin Guan, since Qin Guan said it, he will be able to do it. For example, adding air conditioning to tanks will really add air conditioning. Therefore, Qin Guan now said that it can be done if he can change the Jian-7 to the devil. Therefore, visitors from the date palm country don't have too many concerns.

It's not like the super-7. The engine is unknown. Now, it's just a slight improvement on the basis of the J-7.

In this way, without finalizing the super-7 contract, the J-7 made a breakthrough, which is the same as the process in history, but the time has to be several years ahead of schedule.

According to Qin Guan, this kind of magic reform is more than seven. It will not be done until the mid-1980s at least. Now, it has been several years ahead of schedule.

Time passed quickly. The afternoon passed and night fell.

Plant 1132 is located in a terrain surrounded by mountains, so the climate here is not cold and there is no central heating. Now, it will be cold as it gets dark.

The restaurant in the factory was specially cleaned and clean. At the same time, the tables were put together into large tables. At this time, a dinner party will be held here to welcome the visiting guests.

The people of yezao country will become their big customers in the future, while the people of Niu country will provide advanced technology. Take the improvement of the J-7 as an example. In terms of electronic systems, the Marconi Company of Niu country is the best choice. In history, they have provided these avionics equipment.

Now, the guests of the two countries sit at two tables respectively. Because of different eating habits, it is also convenient to serve dishes. Qin Guan and the leaders in the factory sit at the next table.

"If there is a place with poor reception, please forgive me." Tu said, "since you are here, please taste authentic Sichuan food. In order to take care of your appetite, these dishes are divided into two parts, one is spicy and the other is not spicy."

When he came here, of course, he had to taste authentic Sichuan food. Just hearing Sichuan food, Qin Guan felt that his saliva was about to flow out. Those red peppers were dotted on the dishes, which made people salivate!

Although some part of the body will feel uncomfortable the next day after eating, I have to say that it tastes great.

However, many foreigners can't eat pepper. In their eyes, pepper is a poison. This taste is difficult to accept, so they should make two at the same time.

"Tonight, we just want to eat and drink well."

Foreign wine has been placed on the table for visitors from Niu country, while drinks are used instead in date country. They can't drink.

At this time, you don't need any translation, just make a gesture.

Han cuisine is famous. Many foreigners will praise their dishes after eating them, and now, of course, it is the same.

Beside Qin Guan, there are scholars and Xiang Jing. Since they followed Qin Guan, although they are actively exercising every day, they are not as intense as in the army. Moreover, many times, they can't control their mouths.

Now, Xiang Jing sat there with chopsticks in her hand, closed her eyes and smelled the smell from the air: "I guess it's boiled fish!"

Sure enough, the old lady in the canteen came up with a big basin. On the basin, fish and meat were hidden, while pepper floated a full layer on the vegetable soup. It smelled so delicious!

The pungent smell of pepper made Xiang Jing feel that every cell began to jump, and the hungry stomach began to secrete gastric juice quickly, ready to digest!
