Siheyuan starts from a better life

Chapter 976, New Plane 2
Jiang Yan remembered that he had verified the double delta wing and leading edge maneuvering flaps on the Zhan-7 aircraft with chin intake. This layout greatly enhanced its low-altitude and medium-altitude maneuverability. If the newly replaced turbojet engine could reach Mach 2, it would be quite good.

Coupled with the carefully designed wing fuel tanks, the combat range will be greatly increased, which can completely get rid of the saying that the MiG has short legs. It uses a new airborne radar, fire control system and new air-to-air missiles, which is very powerful.

Jiang Yan also thought that the country is still relatively weak in terms of airborne radar, fire control systems and new air-to-air missiles. If we want to speed up the deployment, we must purchase them from abroad.

Jiang Yan remembered that Israel had an avionics system called EL/M-2021B in the international market. This is a pulse Doppler radar with advanced performance that Israel is developing. Its detection range can reach 60 kilometers and it can track 8 targets at the same time, guiding medium-range air-to-air missiles to achieve long-range beyond-visual-range attacks. However, it is not known whether this radar has been developed yet, so it can be considered as the first choice.

What has been confirmed to be successful is the Eagle-Sauce Monkey version of the AN/APG-66 radar. Although it is a monkey version, its performance is still equivalent to the F-16 Block 15 batch or above, which is more advanced than domestic fire control radars by more than one level.

However, the AN/APG-66 pulse Doppler radar weighs 110 kg and has an antenna diameter of 700 mm, so it takes a lot of space to load it. However, its search distance for a target of 5 square meters can reach 75 kilometers. If the AIM-7M "Sparrow" medium-range air-to-air missile is introduced, it will be even more perfect, and there will be no problem with beyond-visual-range attacks.

Even if it is not possible to introduce the AIM-7M "Sparrow" medium-range air-to-air missile, it is also possible to introduce the Italian "Asped" semi-active radar-guided air-to-air missile. After all, there is a precedent of successful introduction in history.

As for the engine, it is the Bess engine. Jiang Yan heard that this engine that has been redeveloped has brought good news. All problems have been basically solved and it can be mass-produced.

As for the later Flying Leopard, Jiang Yan thought it would probably appear again, after all, the two aircraft have different focuses.

In just a short while, Jiang Yan simulated in his mind the best and most optimal combination of this ultimate version of the Z-7 aircraft.

"Xiao Han, you can't just limit your vision to the lower jaw air intake. I designed the lower jaw air intake in the first place for installing airborne radars. But things are different now. Airborne radars are becoming more and more advanced, and their sizes are also getting larger. The lower jaw air intake area is not enough. If you still install a small radar, you can't guarantee that you will be the first to find the target. It's better to directly use the more popular lower air intake aircraft."

"This is what I think." Jiang Yan said as he casually drew a blueprint of the later Zhan-7MF aircraft.

It is still based on the old Zhan-7. The rear part is basically the same, retaining the original aircraft design. The nose looks like this, like this, and like this.

In the following time, Jiang Yan explained to Jiang Zihan in detail the benefits of improving to downward air intake, as well as the difficulty of the modification.

"As far as I know, the maximum detection range of domestic radar is no more than 30 kilometers. Dad, the 60 kilometers you mentioned is basically unattainable. Research and development also takes time, and there are also air-to-air missiles." After listening to his father's words, Jiang Zihan raised his own objection.

In this way, we can buy Eagle Sauce’s radar, and then Jiang Yan came up with a solution.

After Jiang Yan's explanation of this aspect, Jiang Zihan was greatly enlightened. This was a fairly mature aircraft design. If the above conditions were met, it could basically be put into production with a little research and development.

"It should be noted that if you buy Eagle Sauce's radar later and buy more at one time, we can discuss the production line. We can also develop our own radar. As the saying goes, it's better to have it yourself than to have it from your parents." Jiang Yan then affirmed.

"Dad, can you guide me in making such a design plan?" Jiang Zihan asked.

"Okay, no problem." That night, the light in Jiang Yan's study was on all night. The father and son designed and drew together. There were many quarrels, but everything was developing in a good direction.

Aircraft design is not something that can be done overnight. Jiang Yan and his son spent several days in the study room to roughly design the most basic drawings of the aircraft. The design plan was finally finalized and all the ideas were written down.
"Dad, I'll take the plan and drawings to the research institute right now. If it's approved, I'll probably be transferred with Xiao Rui soon."

"Go ahead and take care of your own business. Don't worry about the family." Jiang Yan said while yawning.

"Son, you don't want to eat anymore." Jiang Sirui asked when he saw his son coming out of the study.

"Mom, I don't want to eat anymore. I have something to do when I get home."

On the way back to the institute, Deng Zirui was driving and Jiang Zihan was lost for a while.

"I heard that you and your son have been staying in the study for several days. Is it possible that Mr. Jiang is giving you some special treatment?" Jiang Wenxing, who has become the director, said as he looked at Jiang Zihan who came to his office.

"Leader, look at this." Jiang Zihan ignored the director's teasing and directly opened the drawings he brought.

"This is?"

The plane on the drawing was one that Jiang Wenxing had never seen before. It looked like the Zhan-7, but a little different. It was a plane with belly air intake, but it looked quite beautiful.

"You and Mr. Jiang, you made this in the study these few days." Jiang Wenxing asked with some disbelief.

"Yes, this plane was named Zhan-7FM by my father. It is the latest version based on the Zhan-7." After Jiang Zihan said this, he introduced the parameters of this aircraft to him in detail.

"Can we produce this?" Jiang Wenxing asked.

"Okay, here are the detailed steps of the design plan." Jiang Zihan said as he handed his notebook to his leader.

"What a wonderful idea! President Jiang is amazing." Jiang Wenxing sighed after reading the contents of your notebook. He had heard before that President Jiang was a genius, a genius with wild imagination. Unexpectedly, he actually used everything to the extreme. Basically, all the existing technologies have been upgraded and improved, and the integration capabilities have been almost used to the extreme. Moreover, the radars and other equipment introduced as shown above are not just those of the United States. There are several international ones that can be used as substitutes, and many of them are from countries that are friendly to us. Even if we fall out with the United States in the future and stop supplying them, we can quickly replace them with substitutes. What's more, the corresponding equipment in China is also being developed intensively, so these are basically not a problem.

Jiang Wenxing took a look at the design parameters of the Z-7FM. According to the plan, if this aircraft is produced, its performance will basically be comparable to the Gallic Mirage F-1 fighter. This part of the technology can even be applied to the Z-8 and Project No. that have already begun development. This combat effectiveness improvement is not a small amount.

"You go back and rest first. I will report to my superiors and ask you if I have any questions." Jiang Wenxing said and left in a hurry.
