Super Weapon Exchange System
Chapter 441: Demon Change Jian Seven
Up to now, there has not been a single aircraft developed by Han, and the J-8 does not count. The J-9 has already died, and the J-10 project has just begun.
The technical personnel of Han State did not have much confidence. It was a fantasy to modify the J-7 to have the same fighting ability as the F-16.
Only Qin Guan knew that this was not difficult at all. The key to this was the double delta wings.
The MiG-21 is only a short-lived in the equipment of the Xiong Kingdom. On the contrary, the Han Kingdom has made this fighter proficient. When it is improved to the level of the J-7E, it is simply the best.
Unfortunately, twenty years later, this kind of nose-intake fighter can no longer gain much advantage in air combat, so it is destined to be eliminated.
But it's different now. Now, before the 1980s, the over-the-horizon air combat in this era has not yet become the mainstream. Therefore, if the J-7E is brought out now, it will definitely usher in a small peak of export.
Among them, the main is the improvement of aerodynamics. The delta-wing type wing is triangular as a whole, while the double-delta-wing type wing is like two triangles, and the sweep angle of the inner and outer sections of the leading edge of the wing is different.
The double delta wing type has better aerodynamic characteristics at large angles of attack than the delta wing type, which can shorten the take-off and landing distance and increase maneuvering flexibility. The delta wing has a large subsonic resistance, while the double delta wing is used at supersonic and subsonic speeds. To a better balance.
The double delta wing actually reduces the sweep angle on the outer section of the wing, which partially alleviates the problem of poor low-speed performance caused by the large sweep angle of the delta wing. After the F-7E is switched to a double delta wing, the wing area and wingspan are increased. , The lift is significantly improved. Therefore, there are even extreme claims. In fact, the side strip wing can also be regarded as a double delta wing with a large internal sweep angle. The main function is to control the vortex at high angles of attack, increase the vortex lift, and improve Lateral stability.
In addition to the double delta wing, the front-edge mobile **** have also contributed a lot, and the improvement in maneuverability is very significant. Therefore, the ultimate improved version of the J-7 has greatly improved maneuverability, which is close to the F-16. It's nothing more than fighting.
Qin Guan knows, but Tu does not know, so now Qin Guan has raised so many, Tu has retreated in his heart, but it has greatly attracted the attention of the date palms.
"Really? If we can meet this standard, we can order a batch!" Abid made up his mind immediately.
For the Super Seven fighter, the date palms have great reservations, 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. The increase in the range, the price will not be too high, fully meet the needs of the date palm country!
"Okay, but I hope you can pay a part of the deposit in advance, because the improvement of our J-7 is completely a self-developed project, and it cannot be carried out without funds." Qin Guan said, "Of course, on the other hand, if Our improvements cannot meet your requirements. We can fully refund these deposits."
If you use your money first, if the performance fails, you can refund it. This fully demonstrates Qin Guan's confidence. There is no reason why the Date Palm Country should not agree to such a condition.
Out of trust in Qin Guan, since Qin Guan said it, he would definitely be able to do it. For example, adding air-conditioning to the tank was really added, so Qin Guan now said that he could change the J7 to the demons. It can be done, so visitors from the date palm country do not have too many worries.
It's not like that Super Seven, the engine is still unknown, now it is just a little improvement on the basis of the J-7.
In this way, without finalizing the super-7 contract, the J-7 made a breakthrough instead. This is the same as the process in history, but the time has been advanced several years.
According to what Qin Guan said, the super-seventh of this kind of magical reform would not work until at least the mid-1980s, but now, it has been several years in advance.
Time passed quickly, the afternoon passed, and night fell.
The terrain where the 1132 factory is located is surrounded by mountains, so the climate here is not cold, and there is no central heating system. Now, as it gets dark, it will look deserted.
The restaurant in the factory was deliberately cleaned and cleaned. At the same time, the tables were put together into big tables. At this time, here, there will be a dinner party to welcome visiting guests.
Chinese date palms will become their main customers in the future, while Niu Guoren will provide advanced technology. Take the improvement of the J-7, Niu Guo’s Marconi Company is the best choice for electronic systems. Historically, they provided these avionics.
Now, the guests of the two countries are sitting at two tables. Because of the different eating habits, it is convenient to serve dishes. Qin Guan and the leaders of the factory are sitting at the tables beside them.
"If there are places where the hospitality is poor, please forgive me." Tu said: "Since everyone is here, please taste the authentic Sichuan cuisine. In order to take care of everyone's appetite, these dishes are divided into two parts. One part is spicy, and one part is not spicy."
When you come here, of course you have to taste authentic Sichuan food. Just hearing Sichuan food, Qin Guan feels that his saliva is about to flow out. Those red peppers are dotted on the dishes, which makes people salivate!
Although after eating, a certain part of the body will be a little uncomfortable the next day, but I have to say that this thing is good to eat.
However, many foreigners cannot eat chili. In their eyes, chili is a poison. This taste is difficult to accept. Therefore, two servings must be made at the same time.
"Tonight, everyone is going to eat well and drink well."
Visitors from Niu Country have already put foreign wine on the table, while in the Date Palm Country, they use drinks instead. They cannot drink.
At this time, no translation is needed, just make a gesture.
The dishes of Han are well-known, many foreigners will praise their dishes after they have eaten them, and now, of course it is the same.
Beside Qin Guan, Xiucai and Xiang Jing are sitting. Since they followed Qin Guan, although they have been actively exercising every day, they are not as strong as in the army. Moreover, in many cases, the two of them can't control it. Own mouth out.
Now, Xiang Jing is sitting there, holding chopsticks in his hand, closing his eyes, and smelling the smell in the air: "I guess, it's boiled fish now!"
Sure enough, the old lady in the canteen came up with a big pot. On the top of the pot, fish meat was looming, and the pepper, floating on the top of the vegetable soup, was full of layers. It smelled really delicious!
The smell of the pungent pepper made Xiang Jing feel that every cell began to jump, and the thirsty stomach began to secrete gastric juice quickly, ready to digest!
