The advantages of the Su-35 lie in the innate performance suppression of the heavy aircraft against the medium aircraft, the larger combat radius and bomb load, and the high comprehensive combat effectiveness and safety.

And from a long-term perspective, the Su-35 has greater potential for body modification, if it is replaced with fourth-generation avionics and radar, and equipped with an omnidirectional axisymmetric vector engine, its combat effectiveness far exceeds that of the ultimate version of the Su-37.

But for the time being, in terms of advanced degree and combat effectiveness, I'm sorry that the J-10D 'Fire Dragon' personally designed by Academician Yang Wei is far superior to Lao Maozi's Su-35.

As for the J-10S returned this morning, it was crushed in all directions.

"Call the tower, and perform a single-machine long-distance transfer task with zero requests." Zhou Hai sighed, gathered his mind, carefully felt the flying experience of the new warhawk under him, switched the communication channel, and sent a request to the base tower.

"The tower received, zero, permission to carry out the mission." The base tower controller stared at the dark green air indicator in the sky and immediately replied: "I wish you a safe journey." ”

"Zero received."

Zhou Hai responded and gently pulled the lever.

The agile and dexterous J-10D 'Fire Dragon' responded, with light transmission control and excellent body performance, without delay at all, and raised its head to meet the dark night sky covered with countless bright stars.

The blue high-temperature tail flame is particularly dazzling, and the bright moon complements each other.

Direction, northeast.

……

Miancheng, a place called Puyuan Mountain.

The mountain is relatively gentle, the woods are dense, there is only one road connecting the outside world in the whole Puyuan Mountain, the highway construction standard is a first-class, the entrance and exit are guarded by the army soldiers, and the stone monument of the military restricted area is set up.

After several kilometers of stretching along this first-class highway in the deep mountains and old forests, you will come to the world-class hypersonic super large wind tunnel, which is strictly protected by the security forces.

"Aang!" In the treetops of the forest, the high cries of unknown birds can be heard.

The night sky is unconsciously filled with cumulus clouds.

"Boom!"

In the hypersonic mega wind tunnel, a special model with an extreme aerodynamic design, constructed of titanium alloy and high-strength anti-ablation composite materials, is subjected to the impact of hypersonic air currents up to Mach 6.

Mach 6, the speed of movement is 2040 meters per second, reaching the standard of hypersonic criticality, which is an extreme flight environment for any aircraft.

At this moment, in the wind tunnel, streams of air are blown out from the nozzle at the top of the upstream, like a turbulent torrent, at a low speed, and then under the action of the extra-large volumetric vacuum vessel connected at the downstream outlet, based on the basic physical laws of blowing up and sucking, the slower air flow is frantically lifted.

The airflow rises sharply towards Mach 6, and during the whole acceleration, the airflow itself expands sharply, resulting in a cooling effect, and then passes through the heating device installed in the wind tunnel stabilization section to maintain the normal temperature and avoid liquefaction.

In the Shiyan area of the center of the wind tunnel, a special metal model blown by hypersonic air currents has a gray black-red surface and a temperature of 1480 degrees Celsius, which is in an extreme environment.

Five seconds!

Ten seconds!

Twenty seconds!

The entire special metal model remains unchanged, the internal structure and aerodynamic shape are not affected by the high temperature, and the high-precision cutting-edge detection equipment installed in the hypersonic extra-large wind tunnel collects a series of extremely important test data, which is continuously transmitted to the database for storage.

"Buzz!"

After the time slowly flowed for thirty seconds, the wind tunnel was closed, the nozzle upstream stopped, and no longer blew a flood of super-large flow of air, and the special metal model located in the central experimental area conducted heat to the outside space.

"The seventy-eighth hypersonic wind tunnel experiment has officially ended, after the experiment, Tianjian-1 meets the extreme hypersonic flight environment of 40,000 meters flight altitude, minus 55 degrees Celsius and Mach 6, the structural amplitude has not changed, the data is normal, the design is correct, we have succeeded!"

In the wind tunnel digital console, more than a dozen engineers and experimenters in white dust-proof overalls gathered, and a middle-aged man with gray temples stared at the computer screen, and when the test data was finally sorted and synthesized, his eyes appeared excited.

Succeed!

A special metal model that is quietly placed in the experimental area in the center of the wind tunnel, through testing,

Inside the console, there was a continuous burst of applause and cheers, and some people even cried with joy.

"It finally worked."

Su Rui, who was standing in the crowd, couldn't help but feel excited in his heart, and he sighed a little, took a deep breath, and quickly calmed down his emotions.

As one of the core members of the entire project team, no one knew better than Su Rui what Tianjian 1 meant.

The aerodynamic model, which is completely scaled down according to the aerodynamic layout, and the internal structure is almost identical to the real version, which is not only a test for the aerodynamic layout, but also for the intake tract and the engine.

The success of this experiment will make the experimental progress of Tianjian 1 a big step forward.

Inside the console, the middle-aged man with gray temples cheered and announced the official end of the experiment, and the crowd gradually dispersed.

Su Rui rubbed his sour eyes, turned around and left the console, and Zuo Xue in a pure white work uniform stood outside the door.

"Mentor, was the experiment successful?"

Zuo Xue, who was standing in place, with short hair flowing and elegant, was beautiful and elegant, holding a high-level document in both hands, watching Su Rui walk out of the console, greeting softly, and paying courtesy.

The words are light and agile, and like a clear trickling stream, warm and moist into the heart.

Dressed plainly, but without losing its own extraordinary beauty.

As a graduate student led by Su Rui, Zuo Xue traveled thousands of miles to Miancheng, Sichuan Province, entered the top-secret super project here, and participated in the Tianjian No. 1 project.

Su Rui, who was full of smiles, nodded lightly to Zuo Xue: "Success, crossed an important obstacle, Xiaoxue, how much have you learned during this time?" We're going to leave soon. ”

"When I first came into contact with Tianjian-1, I learned a lot of precious things, the wind tunnel characteristics of the canard aerodynamic layout and the conventional aerodynamic layout, the transonic aerodynamic characteristics, the design points of the forward-swept wing model and hypersonic weapons." Zuo Xue stroked her falling hair, recalled her experience and study life during this time, and said softly.

Su Rui nodded and said with a smile: "Then I'll test you, what is the content and main characteristics of hypersonic flow?" ”

"Air hypersonic flow, which is mainly characterized by high Mach numbers and large energies, is characterized by hydrodynamic characteristics that are not found in hypersonic flows, including physics and chemistry, in hypersonic flows, shock waves and real gas effects, mutual interference with the boundary layer are particularly prominent, in addition, hypersonic flows are divided into viscous flow and invisible flow." Zuo Xue didn't think about it, recited it backwards, and replied.
