Zuo Xue replied seriously and said the remaining two auxiliary solutions: "Teacher, yes, I borrowed the X-29 pneumatic layout design and adopted a close-coupled canard wing + edge wing to generate a body-destructive vortex, which reduces the force amplitude at the root of the wing, and can also use active elastic divergence technology to maintain the stability of the wing."

The aerodynamic design of close-coupled canard wings + edge wings, as well as active elastic divergence technology.

The former is the aerodynamic result of the US X-29 forward swept wing test aircraft, while the latter is the current cutting-edge technology in the aviation field.

These are two auxiliary solutions, with graphene composite materials as the core, and cooperate with each other to achieve an alternative solution to the problem of aeroelastic divergence.

"The idea is very good, and this can indeed effectively suppress the problem of aeroelastic elasticity divergence."

At Huangtianba Base, Yang Wei, who was sitting on the chair of Director Cheng Fei's office, heard the two solutions that Zuo Xue said, his eyes lit up. He held a pen in his right hand and quickly recorded it on the white paper, praising: "Xiaoxue, tell me about the comprehensive performance indicators of this fighter."

As the developer of the J-20 comprehensive aerodynamic layout, Yang Wei is very aware of the role of close-coupled canard wings + edge wings, and the body-decomposition vortex produced can effectively remove chaotic airflow at the root of the wing.

Yang Wei didn't expect Zuo Xue to realize this and use it.

"I initially named this fifth-generation fighter as Z-2, a single-seat twin-engine heavy fighter, an air weight of 22 tons, a maximum take-off weight of 50 tons, a front radar reflective cross-sectional area of ​​millimeters, a maximum flight speed of M6, a maximum lift of 80,000 meters, and a turbofan oblique knock ramming adaptive variable cycle engine."

When Zuo Xue heard this, he did not hesitate and immediately gave the comprehensive performance indicators of the Z-2 fifth-generation concept aircraft concept: "The maximum range of subsonic speed is 9,000 kilometers, the maximum range of hypersonic speed is 3,500 kilometers, the combat radius is 1,500 kilometers, the flight overload + 12G-5G, the combat range is integrated with aerospace, and the directional energy weapon is used. The specific design has not been completed for the other subsystem content."

"The performance indicator design is not biased, that is, it does not pursue unrealistic high indicators or self-deprecating, which is very good."

After hearing the comprehensive performance indicators of the Z-2 fighter jet released by Zuo Xue, Yang Wei nodded affirmatively: "Xiaoxue, do you have any first draft aerodynamic design drawings and models for the fifth-generation Z-2 aircraft?"

Impartial and precise control.

This is Yang Wei’s evaluation of Zuo Xue.

The comprehensive performance requirements of the fifth-generation fighter are undoubtedly extremely high. On the basis of the original fourth-generation aircraft, the combat range has been raised from full-airspace combat to the scope of aerospace integration. Such high performance requirements will mislead aircraft designers, resulting in errors in design performance indicators.

Design performance indicators are too high or too low, neither can be done.

Zuo Xue has already developed the qualifications of a fighter jet designer, that is, precise control, design and research and development based on the strength of the domestic aviation industry and basic technology.

The most core turbofan inclined knock ramming adaptive variable cycle engine in the entire Z-2 fifth-generation concept looks fantastic and unrealistic.

In fact, according to Yang Wei's understanding, Jiang Zhonglin's team from the Key Laboratory of High Temperature Gas Dynamics, the Institute of Mechanics, Chinese Academy of Sciences, is conducting a hypersonic wind tunnel experiment for oblique knock ramjet engines in Miancheng, and the performance indicators fully meet the requirements of hypersonic flight.

Calculate the time, the experiment is already underway.

"There are first draft aerodynamic design drawings, but there are not yet models." Zuo Xue replied truthfully, feeling a little embarrassed.

After talking for a long time, in fact, the so-called Z-2 fighter that can carry out M6 hypersonic cruise is not even in PPT state, and outsiders sound like bragging.

This is quite embarrassing.

Of course, as a national defense researcher, Zuo Xue is not called bragging, but can be called academic discussion and exchange of scientific research ideas.

Yang Wei didn't care about this and comforted him: "It's okay, the development and design of fighter jets is not a day's work. I'll send the first draft aerodynamic design drawing to me first. Is the model in a while? Have you done finite element analysis?"

"I did it. I just ran out of the supercomputer yesterday. The data of the pneumatic design matches the data. I will send it to you immediately." Zuo Xue responded and handed over the confidential phone to the left hand. Then he controlled the mouse with his right hand and clicked the top secret file of the Z-2 fifth-generation machine project in the screen. Through the internal communication and encryption channel of the national defense scientific research system, it was sent to Yang Wei, a teacher far away in Huangtianba, Rongcheng.

Yang Wei clicked to receive the entire top-secret scientific research document, and then formulated the secret level as Director Cheng Fei: "I received it. Regarding this document, the confidential level is tentatively third-level top-secret. I am looking forward to making the Z-2 aircraft model when I have time."

"Okay, teacher." After hearing Yang Wei's words, Zuo Xue smiled and nodded in response.

"You go and do it first. Remember, you can report to Chengfei in a week. Okay, that's it, it's fine for the time being." Yang Wei gave in again, and then hung up the phone.

"drop……"

In the confidential phone, communication blind sounds are heard and telephone communication is interrupted.

Inside the house, he fell into silence again.

Outside the window, there was wind and rain.

Blows of wind blew the canopy, leaves fell down, flying all over the sky, messy.

"Z-2 has a feasibility without a vertical tail variable forward sweeping wing, but graphene composites must meet performance requirements. Two nines are just the basis, and three nines are better. Unfortunately, the higher the purity, the more expensive it is. I hope that domestic graphene mass preparation technology can make breakthroughs in ten years." Zuo Xue put down her confidential phone, her black hair like a waterfall swings gently, and her eyes condensed the sci-fi Z-2 fifth-generation fighter in the screen, thinking silently in her mind.

Fighters with high maneuverability, high stealth, high intelligence and directional energy weapons are like to call them the sixth-generation fighter, while Zuo Xue prefers to divide them into the fifth-generation fighter sequence.

In the high-definition display, it consists of two first drafts of aerodynamic shape design, one is the body structure at the maximum forward sweep angle, and the other is the wave-bike body structure with the wing shrinking and a diamond-shaped appearance.

The two design drafts of the finite element analysis program have been completed, and the appearance looks extremely sci-fi. The first one is extremely aggressive and aggressive, just like a fierce beast, and the second one is elegant and noble, full of technological sense, like a visitor from outer space, without any of the current characteristics of any aircraft on Earth.

The two design drafts describing the same fighter jet have a very contradictory atmosphere of elemental conflict. This is the Z-2 fighter jet that is quietly staying in the electronic draft picture.

For the Z-2 fifth-generation concept aircraft, if it is really selected into the national fifth-generation fighter development plan, Zuo Xue only hopes to be successfully developed within fifteen years.

Fifteen years.

That is, a long and short fifteen years.

For ordinary people, fifteen years is extremely long.
