Chapter 159: How to improve J-7

The J-7 fighter is an imitation produced by the MiG-21 of Xiong Guo imported from Han.
In Xiong, the MiG-21 was just a flash in the pan, and was soon replaced by aircraft such as MiG-23. In Han, this aircraft has blossomed and continued to produce, forming a huge family of Seven Lords. Even Jianba is a double-shot enlarged version of Qiye.
After truly mastering the technology of the MiG-21, the J-7 is also constantly improving, especially the appearance of double delta wings, giving the J-7 a good close-range combat ability.
However, the air intake of its nose makes it impossible to install a large-caliber radar, which is always a shortcoming.
Therefore, if the J-7 wants to continue to improve, it must work the nose.
Change the nose air intake to the belly air intake. The head space is freed, and then a large-caliber radar can be used. At the same time, the structure of the nose is increased in weight. For trimming, a front is added. With small fixed canards, the J-7 MF model appeared, which can be said to be the ultimate improved model of the J-7.
Unfortunately, in history, the most powerful model of the J-7 was not mass-produced.
There are of course many reasons.
The most important thing is that the birth is out of time.
Factory 1132 is the supporting production factory of the 6611 Research Institute. At the same time, there is also a design office in Factory 1132, which later developed into the Aircraft Development Center/Technology Center of Factory 1132. This J-7 MF project is actually the design room of Factory 1132. Made it out.
At that time, the factory's development of the J-7MF was a purely foreign trade project. To put it ugly, it was an inexplicable spare tire plan. If Xiaolong fails to make it, it has a chance.
At the same time, the demonstrator before the F-7 MF is the F-7 FS, which is a real machine built, and the F-7 MF has only an overall design idea and model.
Later, the project came to an end, because there were no potential customers and no start-up funds could be obtained from outside. The internal reason is that the J-10 had already flown for the first time at that time, and the 1132 factory was definitely the main engine factory; the Xiaolong would be 100% produced at the 1132 factory.
At that time, there were orders for the double delta wing J-7 for export, and the Air Force’s successor to the 7G order, and the 1132 production task was also full. In this way, apart from appearing at several airshows, there is no more to follow.
That's because it's too late. What if you do it now?
Use the fierce dragon in front of you to study its technology, and then get the body of the J-7, and come up with an enhanced version of the J-7?
Later generations' research is a positive study. Firstly, they improved the technology of the J-7, then made the Super VII, and then the Xiaolong. In the end, the Xiaolong repaired the fruit and obtained foreign orders, went abroad, and became a special foreign trade machine.
But now, it is going to go back, using this Xiaolong's technology to improve the current J-7. Changing it back in this way will definitely bring the J-7 to a higher level.
In future generations, it will be the end of the nineties and the beginning of the twenty-first century, and now, not even the eighties, now if it is improved, the potential is definitely huge.
Thinking of this, Qin Guan made up his mind. Since he has come here, since he has transformed Xiaolong, of course, he can also express the idea of ​​this J-7 MF.
When Qin Guan came in, most people didn't have any trust in Qin Guan. After all, Qin Guan was too young, and it was not in their aviation circles!
But now, Qin Guan has conquered them with facts one by one. In their eyes, Qin Guan has become an expert.
How to improve the J-7?
Qin Guan elaborated on his plan in detail.
Unfortunately, there is only one model for the J-7 MF in later generations, and I am afraid that technical data can not be found. Therefore, Qin Guan can only talk about ideas, but only ideas are enough. After all, Qin Guan's contribution is to put forward ideas!
This said, his mouth was dry, and for more than an hour, Qin Guan squatted on Xiaolong's wing, began to explain to the people below, and then answered each of their questions.
time flies.
The sky outside slowly darkened.
While Qin Guan was exerting his abilities, Xiang silently stayed in a corner, paying attention to Qin Guan. In her eyes, there were more and more mysteries in Qin Guan's body.
His superpowers can be displayed not only in the army, but also in the equipment of the air force!
This Qin Guan is really interesting.
As you get to the back, the following questions become more professional, and Xiang Jing can't understand it at all.
"In other words, if our radar wants to have pulse Doppler capability, it is better to use a digital processing circuit in the back? It is better to need a central processing unit?"
"Yes, the use of digital processing is also convenient for future upgrades. At that time, as long as we improve the software, we can make the airborne radar have better performance. Of course, it may take a long time, five or even ten years. I believe that as long as we choose the right direction, we will succeed."
Having said that, Qin Guan felt his stomach scream.
"Everyone, we will stop here for today, can anyone tell me where to fill my stomach?" Qin Guan said to the people below.
It's time to eat.
Technicians have such characteristics. Once immersed in the academic ocean, they will forget everything.
"Yes, yes, let's go eat first." Old Song said, "Go, let's go to the cafeteria."
In the canteen of the base, the food had been prepared long ago. When a crowd came in, there was no overcrowding. Qin Guan quickly walked to the forefront, picked up the plate, and started to serve the food and rice next to him.
Then, Qin Guan came to the front of the table, put the plate on the table, and felt something was wrong just before he was ready to eat.
These people.
Although it was a meal, these technicians sat up around Qin Guan after they had a meal. The people sitting beside Qin Guan were all a few years old, maybe they were the leaders of various research institutes.
"Comrade Qin Guan, according to your statement, does our variable swept wing technology still need to be studied? If it is used in the assault fuselage, is there a market?"
attack plane? Qin Guan took a bite of his meal and remembered the progress of various research institutes in history. Now, all kinds of aircraft in the country have fallen behind, so he needs to invest in all aspects.
At present, the main force of the strong five was developed on the basis of the J-6, and it has long been behind. The country urgently needs a new attack aircraft. As a result, a certain factory finally obtained the approval and copied it on the basis of the MiG-23. A strong six attack aircraft with swept wings.
This project, of course, will not succeed. The MiG-23 is already very heavy. As a result, the reverse imitation of the strong six is ​​16% heavier than the MiG-23's variable swept wing system. In particular, The control problem of the variable swept wing system could not be solved, and the project was finally discontinued.
Now, this person in front of him, is this project leader Lu Lao?
