"The Z-1 concept aircraft is designed based on this concept, with stealth performance as the core primary performance indicator. After I learned the design advantages of the fourth generation aircraft such as the F-22, J-20 and FC-31, the stealth performance of the Z-1 concept aircraft solution was further improved and improved, and the forward RCS reached the standard of 0.001 square meters."

Zuo Xue's gentle and light voice revealed a hint of pride.

0.001 square meters RCS data!

This is the ultimate stealth performance of the Z-1 concept machine solution after final improvement and optimization, and can be said to have reached the peak level of the fourth generation machine.

According to the latest generation of fighter jets, the fourth-generation fighter jets are divided into three stages according to stealth performance—

Early Fourth Generation,

Four and a half generations,

The peak of the fourth generation.

The final solution of the Z-1 ‘Ghost’ concept machine is 0.001 square meters of RCS stealth performance, which is at the peak of the standard fourth generation.

The theoretical forward RCS of F-22 is 0.004 square meters, which is about 40 square centimeters, and it reached the level of four and a half generations at the beginning.

Well, now it is also the fourth and a half generation level.

As for the joint multi-purpose stealth fighter F-35, the stealth performance indicators are barely qualified, with the forward RCS reaching 0.01 square meters, that is, 100 square centimeters of forward RCS, which is an early standard and is considered an entry-level stealth fighter.

As the core RCS stealth data indicators of Z-1'Ghost' were announced by Zuo Xue, the field was shocked, and everyone was stunned and confused.

Shocked!

Unparalleled shock!

A turbulent torrent rolled in, sweeping the hearts of participants from both China and Iran.

"What's going on? The stealth performance indicator reaches 0.001 square meters." Lin Jian's face suddenly became serious, his eyebrows were furrowed. Looking at the confident Zuo Xue and the digital screen, he felt that the situation was a little unexpected, and his eyes quickly turned to the major general of the Air Force beside him.

This performance indicator is higher than that of the J-20.

The Air Force Major General had a natural face, and obviously had some understanding of the performance of the Z-1 concept aircraft. He shook his head gently and indicated nothing was wrong.

Lin Jian understood, nodded without saying a word.

"How is this possible..." Han Cheng's eyes were full of incredible expressions, his head was severely impacted, dizzy, and he was incredible.

0.001 square meters, the forward RCS is only 10 square centimeters, which has reached the peak of stealth performance of the fourth generation of aircraft.

As the deputy chief designer of the general department, Han Cheng clearly understands what this set of performance means!

The paper stealth performance of the Z-1 ‘Ghost’ concept machine is one level higher than that of the J-20 and CF-24 ‘Dark Halberd’.

My family knows their own affairs, and the forward RCS parameters of the J-20 "Weilong" are basically the same as those of the F-22 and are still at the fourth and a half generation level.

Han Cheng was really unbelievable about the performance of the Z-1. He stared at Zuo Xue with his eyes, wanting to know how this big boss did it.

If the stealth performance of the Z-1 concept machine solution is true, the CF-22'Dark Halberd' will definitely be eliminated, which is a situation he cannot accept.

"Designer Zuo Xiaoxue, is this true? This Z-1 concept machine really reaches 0.001 square meters of forward RCS performance?!" Kadar was shocked and stood up in an instant, looking at Zuo Xue incredibly.

"Hello, General, it's true." Zuo Xue said affirmatively.

At this time, Alberts, the messenger who belonged to the leader, was a little confused. With a little puzzled look, he turned to the aviation expert sitting beside him for answers. He only knew that the stealth performance of the fourth-generation fighter was very important, and he did not know the true meaning of the 0.001 square meter forward RCS.

"Sir, the stealth data of the F-22 fighter jet is generally considered to be 0.004-0.005 square meters forward RCS." The aviation expert with a beard on his chin said a reference.

"I see."

The messenger Alberts suddenly realized and instantly understood the significance of the Z-1 concept machine's stealth data

The stealth performance of the F-22 is 0.004 square meters, and the stealth performance of the Z-1 ‘Ghost’ concept machine is 0.001.

In other words, the high stealth performance of a Z-1 is equivalent to four times the F-22 benchmark parameters.

Quadruple!

A number that cannot be ignored.

"The Z-1'Ghost' originated in 2019. It combines the advantages of many fighter jets in service. It adopts the front wings of the fuselage + medium trapezoidal wings + double inward tilt movable vertical tail + full-move flat tail air dynamic layout, cancels the canard wings, the overall lift coefficient is 1.8, the air intake is DSI scheme, and the tail nozzle adopts diamond cooling measures to reduce the radar reflection surface and suppress infrared radiation. The radar reflection lobes are reduced to 5, and the stealth effect is excellent."

After everyone slightly digested the super high stealth performance of the Z-1 ‘Ghost’ concept machine, Zuo Xue continued to explain the technical report and revealed the body’s aerodynamic layout and other important performance indicators:

"In terms of maneuverability, two 19-ton vector turbofan engines are equipped with power system to meet the requirements of supermaneuver and supersonic cruise performance, which is generally average. In addition, due to the reduced volume of the new vector engine and DSI air intake, the depth of the main built-in ammunition compartment reaches 0.6 meters, with 8 mounting points, and the depth of the side ammunition compartment is 0.4 meters, each with 2 mounting points, and the total number of hanging points reaches 10."

Pursuing ultimate stealth performance, situational awareness performance is second, and maneuverability is average. This is the overall situation of Z-1.

Fighter design, there is gain if you have a gift.

If you choose to improve stealth performance, performance needs to be reduced in some aspects, and it is impossible to be perfect.

Of course, it has to be said that the Z-1 is the only selected model inside Chengfei that does not adopt canard layout, and the other three models all use close-coupled canard layout.

Zuo Xue canceled the canard to maximize the body's stealth performance.

Compared with the improvement in maneuverability of losing the canard layout, the benefits brought by maximizing stealth performance are extremely significant.

Everyone present agreed with this design concept and expressed their affirmation.

After the small problem link before Zuo Xue's report, now everyone understands the importance of stealth performance.

"It turned out to be done through pure design, which is too strong." Han Cheng was stunned when he saw the aerodynamic layout structure diagram of the Z-1 concept machine on the digital large screen, and his scalp was numb.

exaggerate.

It's just that exaggeration.

The Z-1 concept machine actually achieved the forward RCS index of 0.001 square meters through pure design!

What is pure design concept?

It is entirely based on the strength of the fighter designer and with his magical power, he designed a fighter with extremely high stealth performance, without relying on other auxiliary measures and technologies to reduce the RCS area.

Xu Yun and Cao Ping'an frowned and thought to himself that they were troublesome. They glanced at Zuo Xue next to them, but they didn't expect that the other party was the real opponent of this review meeting.

"The basic performance indicators of the Z-1 stealth concept aircraft are - the maximum flight speed is Mach 2.2, the maximum flight altitude is 22,000 meters, the range is 4,500 kilometers, the combat radius conversion ratio is 0.43, the combat radius is 1,935 kilometers, the self-weight is 19.5 tons, and the maximum load is 42 tons..." After the design concept was explained, Zuo Xue entered the next stage and reported the basic performance design indicators of the Z-1's 'Ghost' concept aircraft.

The light and erotic voices like a trickle of streams filled every corner of the conference hall, and the entire technical report information was faithfully recorded by Tianji who was staying in secret.

Everyone in the Iranian Air Force delegation, whose mood gradually calmed down, was fully focused and listened carefully like students in the classroom, and did not dare to miss a single thing, for the sake of misjudgment and mistakenly choosing a fourth-generation fighter jet that did not meet the needs of the motherland.
