Restarting the national-level strategic deception plan means that the country has reached the most important juncture and urgently needs precious and sparse time.

Endangered.

Yes, it is now a juncture. Whether the fifth-generation fighter, which symbolizes the successful development of the new generation of cutting-edge weapons, can be completely determined by graphene composite materials.

You must deceive, you must deceive.

If Americans don't know, it's best not to let the other party know.

If Americans know, disturb and block as much as possible.

"Finally, we will evaluate the potential of deep application of graphene and start promoting large-scale graphene preparation technology. The graphene production line with an annual output of 20 grams is far from meeting the demand. We cannot rely too much on strategic deception plans. We must be hard on our own."

**The tone eased, and I returned to the scientific research route to make relevant arrangements. I stared at Lin Jian, who represented the army, and said solemnly: "That's all for the time being. This information exchange is top secret. Colonel Lin, you need to notify the army immediately. Our time is very precious."

Time doesn't wait for me, every second will be fought for.

"Okay, Academician Yang, is there anything else?" Lin Jian, who had already learned about the urgency of time and the importance of graphene materials, nodded immediately and asked again.

"No more, Colonel Lin, you go first. I will write the letter and hand it over to you." ** shook his head and responded.

"yes."

Lin Jian did not dare to delay, so he stood up and saluted **, then turned around and left, preparing to notify his superiors.

The office door was opened again and closed again.

Inside the house, it fell into silence.

"Graphene composite materials will surely launch a revolutionary change in the field of aviation materials. From the perspective of basic research, the upper limit of carbon fiber composite materials is much lower than that of graphene composite materials. Not only the forward-swept wing models will benefit from it, but the existing aerodynamic layout and the No. 25 Project use graphene composite materials will also greatly increase the overall performance. Zuo Xue will be the first achievement."

I held up half a cup of cold white glass with my right hand, took a sip, and a coolness flowed through my dry and hot throat. I fell into deep thought. After thinking about it, I came to a conclusion. My eyes immediately turned to the Z-2 fifth-generation machine plan on the confidential computer screen. My eyes flashed: "No vertical tail can change forward sweeping wings... Give me a chance. This plan is very **. See if it can be achieved. It is good. If it is not successful, it is considered an experimental exploration in the field of forward sweeping wings. At present, the research on the field of forward sweeping wings has stopped at the divergence of aerodynamic elasticity. I don't know whether there are still good things to dig in the deep level. I don't know. I'll take this opportunity."

Chance.

**I want to give Zuo Xue a chance, or give the Z-2 fifth-generation machine on the computer screen a chance.

The variable forward swept wings without vertical tails are aerodynamic layout schemes that are even better than the pure forward swept wing design, but generally meet the performance requirements of the fifth-generation aircraft.

The advantages of the aerodynamic layout of the forward swept wing are mainly high lift-resistance ratio, high maneuverability and control stability, suitable for sub-transonic flight, completely overcome the problem of wingtip stall, and extremely high aerodynamic efficiency.

In the sub-transonic stage, the forward swept wing design can almost be said to be an invincible existence, giving fighter jets unprecedented maneuverability and combat effectiveness.

However, there are gains and losses.
