Although Qin Feng has been busy in Chengdu, he is almost at the 3:00-1 line, in the dormitory, canteen, airport, and visiting the factory. This is the first time in recent months, so Qin Feng has seen this unique fighter jet for the first time.

J-7 fs.

It is the latest facelift of the J-7. From the cockpit to the back, it is no different from the original J-7. It is exactly the same, but the front nose is very different.

What does this look like? It is extremely ugly, like a strange bug with a special chin!

"This aircraft was developed by our own funds. In order to fly as soon as possible, we used an ordinary J-72 modified. After all, we only verified the nose. After the verification is completed, if there is an order, we will use the latest J-7 e fighter to make such improvements." The person responsible for the development of this aircraft is Mr. Lu from Factory 132. He faced Lao Ba's guests at this time and proudly declared: "The most important thing about this aircraft is to realize the need to change the nose. Without changing other situations, it has left enough space for the nose to install radar, so that the J-7 has the ability to fight beyond the visual range."

In recent years, the 611th Institute and the 132nd Factory have been merged, but the original 132nd Factory remains. For them, developing a brand new model without this ability, even Tu Laozi had to cooperate with the outside world. However, modifying the J-7 is everyone's strength, so this modified J-7 appeared in such an alternative form.

It is not an air intake on the belly. If it is an air intake on the belly, it should be a hole behind the landing gear in front. As the air intake, the air intake of the aircraft still forms an arc-shaped structure in front of the landing gear. On it, it is a pointed cone nose, which looks inconsistent.

A mature plane should be a beautiful plane, but the one in front of you can't say anything beautiful.

Qin Feng is also familiar with the internal structure of the J-7 fighter jet. When he saw this aircraft, he understood that this was also to minimize the changes in the nose and save costs.

All the original air intakes were used, and they only blocked the original circular air intake, turning them into two upper and lower sections. The opening below was larger, and the radar was installed on the top.

Even simple improvements require systematic engineering, including blowing a wind tunnel and various tremor experiments. The factory raises funds to develop such fighter jets, which is naturally for sale.

In order to save money to the greatest extent, it is inevitable to use existing fuselages to modify it. However, after Qin Feng saw it, he knew that Lao Ba would not be interested in this plane.

"I see, this plane is very similar to a pirate." General Mill said.

Hearing his words, Mr. Lu immediately nodded: "Yes, the improvement of the air intake of our aircraft is to refer to the American A-7 Pirate Attack Plane similar to the jaw-type air intake. This improvement has two advantages. First, it increases the volume of the nose to facilitate the installation of high-power airborne radar; secondly, it improves the air intake efficiency during flight at a high elevation angle, thereby enhancing the maneuverability of the aircraft."

The goal of improvement now is to try every means to increase the volume of the nose. In the past, the radar could only be installed in the air intake cone, so small range measurement radars or simple Doppler radars could be stuffed into it. It can only be said that it is better than nothing. Now, it is different. By using jaw-type air intake, the space of the nose can be larger and larger radars can be accommodated.

"What kind of radar is installed on this nose?" General Mir continued to ask.

"Our current prototype is equipped with Israel's 2032 radar. Of course, it can not only be equipped with this kind of radar, but also other radars to choose from. The radar antenna diameter is about 600 mm, and can be installed, such as the American Apg-68, Russian beetle radar, etc. We will install whatever you want."

Israel used to be self-reliant and planned to develop the Lion fighter, but later gave up under the pressure of the Americans, and they encountered many problems, but they did not give up all of them. The airborne equipment was developed by them, and they also successfully developed it, including this el/m2032 radar. After they developed it, they began to promote this radar all over the world. They even had a pocket version that specifically narrowed the radar antenna and could be stuffed into the air intake cone of the J-7.

Now, it depends on whether there are buyers.

In addition to this kind of radar, there are other radar options. In short, this level of radar can basically meet the guidance needs of medium-range missiles and realize the ability to attack beyond the visual range.

"After such a head is improved, the self-weight will also increase, right?" General Mill is indeed an expert. He suddenly asked a key question. How is your mobility? After the self-weight increases, the mobility will be reduced, right?

"Yes, in order to make up for the increase in self-weight, we replaced this aircraft with the latest Turbojet-13 modified engine. This engine was improved on the original Turbojet-13. Its maximum thrust at home has been increased to 78,000 N, which is the engine with the largest thrust we can use at hand."

The domestic engines are also being gradually improved. At the beginning, they used the Turbojet-7. Later, after the introduction of the MiG 21mf, they were surveyed and mapped and imitated, becoming the Turbojet-13. In order to master this engine, they also made great efforts and took many detours. Later, the technology was finally fully mastered, and new means could be used to improve it. The maximum afterburner thrust of this engine was increased to 78 thousand nm, which has been greatly expanded compared to the 56 thousand nm thrust of the Turbojet-7 before.

Qin Feng also sighed that if there was such an engine at the beginning of the Super Seven project, even if there was no Sword 2 plan, Mr. Tu would have already created the Super Seven. At that time, there would be an engine with insufficient thrust.

Now, the thrust of the engine has come up, but the time has been delayed for more than ten years. The Turbojet-13 has become the last emperor, and Lian Po is old.

This kind of engine can not only be installed on current aircraft, but also used to improve the previous J-7. For example, the latest J-7 e must be replaced with this kind of engine.
