J-8, this high-altitude and high-speed fighter, is still the most high-end model of the Han Kingdom, after all, from the point of view of size, it is the largest, from J-5 to J-7, the size is small, the absolute category of light aircraft, until J-8, it can be regarded as a twin-engine medium-sized aircraft.

However, the nose air intake of the J-8 has caused great restrictions on its performance, it cannot install a large-caliber fire control radar, and it cannot achieve medium-range air combat, which is also the most desired performance now, so, even without Qin Feng's participation, it is also an inevitable plan to change the nose air intake to both sides, and now, finally, the J-8 has been changed.

Qin Feng and Gu Tingting came to Shenyang, it is summer now, the climate in Shenyang is quite good, there is no humid and stuffy heat in Chengdu at all, Gu Tingting looked at Xiaohuzi at home, and Qin Feng came to Factory 112.

The combination of factories and institutes, 601 institutes, supporting is the 112 factory, which is China's old industrial base and the big brother of China's aviation industry, and now, the latest J-8 fighter is also produced from here.

"How's it going, our new plane is good, isn't it?" Qin Feng's side, Mr. Gu said to him with a smile.

The second half of Mr. Gu's life was almost spent on the J-8 model, and now, he is working on the J-8 2 fighter, from design to production, this fighter has always been presided over by him.

He looked at this plane like his own child, and Qin Feng's eyes kept staring at the nose in front of him, which looked like a fighter jet!

The nose is conical, and the position of the airspeed tube has been received forward, and the huge nose has finally come out, with this nose, you can install a large-caliber radar, although now it is empty inside, and the supporting radar does not know when it will be made, but after all, there is already a foundation.

The nose of the aircraft extends to the rear, with the cockpit in the middle and the air intakes on either side.

The entire nose looks almost identical to the MiG-23.

Behind the flat air intake, there is an additional intake door, which needs to be opened at low speeds to avoid insufficient air intake.

"In the past, there was room for the air inlet in front of the nose, so a lot of space in the nose was wasted, but now it can be used to install equipment." Qin Feng walked to the side of the plane, touched the dark green nose, and said to Mr. Gu: "Moreover, the air intake on both sides, one engine, and one air intake, there will not be a situation where we used to turn off all of our engines at once when we were in the test flight." ”

At the beginning of the test flight of the J-8, there were many risks, the biggest risk was the ignition in the air, and the two units were all turned off at once, which caught people off guard, and the J-8 did not crash in the test flight, in addition to the superb skills of the test pilots, it was really an element of luck.

At that time, it was because the two engines in the air intake grabbed the air, and now, changing to the air intake on both sides, there is finally no need to grab it.

"Qin Feng, you are very familiar with our aircraft, do you want to fly this first flight of J-8 2?" Mr. Gu said.

Qin Feng finally came to Shenyang, this time Qin Feng went to visit the United States, and as a result, he defeated the Tomcat with the MiG-21, and now Qin Feng's name has spread throughout the aviation community, and of course Mr. Gu hopes that he can stay here.

It's not easy for Tingting to go back to her parents' house, and Xiaohutou can't always see her parents, if everyone goes back to the 601 Institute to work, won't this be a family reunion? You are not the lonely person you used to be, you have to think that you have a family, a wife and children.

"I'm sorry, grandpa." Qin Feng has already married Gu Tingting, so he has changed his words, except for formal occasions, he usually calls grandpa.

"I came to our Shenyang just to visit relatives, and in two days, I will have a new mission."

Compared with the test flight of J-8 2, there are still greater challenges waiting for Qin Feng, going to Pakistan, not to travel, and when you get there, you have to carry out more confrontation flights.

Pakistan, with a large number of fighters and rich combat experience, in addition to J-6, they also have Mirage 5 and F-16, especially F-16, last time against Tomcat, this time Qin Feng can't wait to confront F-16, neither of them has medium-range air combat capabilities, this kind of confrontation is comparable.

Mr. Gu nodded: "Okay, you have your choice, and I don't force it." However, you must also know that our own things are not lagging behind, and as long as we continue to improve, we can always reach the world's advanced level. ”

When Mr. Gu said this, he was still looking at the plane in front of him, for him, the J-8 2 has been modified until now, and the appearance is already perfect, just like a beautiful man in the air.

"Do you mean avionics?" Qin Feng asked.

Avionics has always been a weak point in China, and although the Air Force has been inspecting abroad, the J-8 2 is now the most reliable interceptor that the Air Force can get, and it will inevitably become the main force in dealing with the invasion of the north.

"No, it's not just avionics, it's its engines." Mr. Gu said: "With the change of air intake on both sides, the nose is free, and the radar equipment is installed, our J-8 fighter will inevitably increase a lot of weight compared with the previous one, so that the thrust of our original engine will be insufficient." ”

The reason why the J-8 can succeed is that based on the existing technology, the J-7 is enlarged, and a twin engine is made, which looks similar to the Soviet Su-15, and now, even if two turbojet-7 engines are used, the thrust will be insufficient, because, if a large radar is installed, the weight will increase a lot.

How much does a large airborne radar weigh? Take the later Su-27 as an example, its huge inverted antenna, the backward electronic processing system, plus its heat dissipation system, the entire radar weighs a ton!

Even the AWG-9 radar created by the most advanced technology in the United States weighs half a ton, and the entire J-8 weighs in total? Adding an extra half a ton of weight to the nose of the aircraft, in addition to the trim problem, has a great impact on the performance of the aircraft!

There is no radar equipment installed yet, so this is not too serious, and after the radar is installed, it can be displayed at once, the climb rate will be reduced, and the maximum speed will also be reduced, and the old business of the J-82 is high-altitude and high-speed interception operations.

So, if you want to improve its performance, you need to change the engine, but what engine?

J-7 actually encountered this problem, now the domestic mapping of the MiG-21MF, but also surveyed and mapped its engine, gave a turbojet 13 model, but, this engine is still far away, their own J-7 is also waiting for this engine, J-7 3's stout body, turbojet 7 can't push it.

Although the J-8 2 has not yet made its first flight, Mr. Gu has already begun to worry about its engine.
