There are so many cameras deployed in the entire outfield at very many angles that no situation with the black ribbon can escape the surveillance, even the smallest anomaly.

After moving his hands and feet for more than ten minutes, the tower approved Li Zhan to run on the ground.

Li Zhan pushed the throttle stick to the half-throttle position, and the two new turbofan engines instantly spewed out a scorching blue tail flame, and it was obvious that the black ribbon had supersonic cruise capability without afterburner. This is also one of the hallmarks of the fourth-generation aircraft.

The two engines burst out with powerful thrust, and the engine speed increased very quickly. Li Zhan had already strongly felt this when he was interviewing the car on the ground. When he released the brakes, a deeper feeling came.

Very, very textured, acceleration is fast, but not the kind of light and fluttering, but like the acceleration of a large-displacement naturally aspirated D-class car, the speed goes up unconsciously. It's a bit like the J-11 series and J-15, which are significantly different from the J-10 series.

The nose of the plane jerked up, and it was absolutely amazing.

As the so-called black ribbon rises, everyone has to bow their heads.

The runway is relatively long, and Li Zhan calculates the distance to leave enough room for deceleration. He noticed that the length of the runway for the Black Ribbon to reach take-off speed was just over 300 meters, and if it was driven by afterburner, it would definitely be able to run into 300 meters. This is definitely the best in the world.

When decelerating, the full-motion canards and the full-motion twin vertical tails can provide strong braking power, thus giving a very impressive deceleration distance. As he returned to the take-off position along the taxiway, Li Zhan was immersed in shock.

He even imagined that if the ground support could keep up, the take-off and landing performance of the Black Ribbon could be completely deployed at the front-line airfield, and there was no need for a long runway, and three to five hundred meters would be completely sufficient. Some two-way six-lane and eight-lane highways and high-grade highways are fully capable of taking off and landing black ribbons.

Of course, the logistics support of the black ribbon is definitely a nuclear bomb for the current logistics support system. This is a stealth fighter, if there is stealth paint, every flight has to do a complex support, it will definitely be the pressure of the aircraft maintenance detachment.

Countries have made their front-line fighters durable and tried their best to simplify maintenance precisely because front-line airfields are usually in very harsh conditions, and there are no paved runways. In the sequence of our army, among the fighters, probably only the Qiang-5, a low-key and luxurious attack aircraft, has the ability to take off and land at field airports.

It is said that the Qiang-5 is low-key and luxurious because the old man has thrown nuclear bombs and has shouldered the heavy responsibility of aerial nuclear strikes for a long time. Later, after the H-6 was changed, the old man Qiang-5 was relieved of this burden.

After three consecutive runs, Li Zhan basically found his senses.

The time came to 8:25, and Li Zhan returned to the take-off position again.

On the tower, out of careful consideration, Bao Guanhua asked Chen Ming to be in charge of the specific command, so of course Chen Ming sat on the main conductor's seat, and Bao Guanhua sat on the deputy conductor's seat.

Chen Ming picked up the red microphone, "Dongyu, get ready to take off." ”

"Dong Mi understands that he can take off." Li Zhan buckled up his oxygen mask, because the sky was gray, so he didn't put down his goggles.

He hit the joystick again to check the controllable wing surfaces, and then stepped on the brakes, the throttle lever opened the afterburner, and the speed soared violently, so fast that Li Zhan was taken aback. He quickly released the brakes, and the black ribbon nose jerked up, and then rushed out.

After taxiing for more than 200 meters, Li Zhan gently pulled up the nose of the plane and then quickly leveled it and retracted the landing gear at the same time, and the black ribbon flew at a height of about five meters from the runway, like a ghost. The people on the tower were already dumbfounded.

I know that Li Zhan is a fierce man, but I don't know that he is so fierce!

The problem is that the performance of this master has far exceeded their psychological expectations, and although they have tried hard to use their imagination, it seems that there is still a long way to go from the real flying skills of this master.

"Fierce man!" Chen Ming couldn't help but sigh, "I still give him a teacher, and he is almost the same as a teacher for me." ”

Whoever has flown this way of taking off before, no one.

More exciting is coming.

The black ribbon hadn't flown a kilometer yet, Li Zhan suddenly slammed the nose of the plane, and the black ribbon suddenly tilted back ninety degrees, drew an arc-shaped ninety degree angle at an ultra-low altitude, and then roared and climbed vertically at a very fast speed.

"This is the real dry land onion pulling!" Chen Ming was amazed.

Don't think it's a performative way to take off. Take full advantage of the agility and super-maneuverability of your fighter to get off the runway in the shortest amount of time, then gain altitude in the shortest amount of time and get into combat mode in the shortest amount of time.

Just like Lao Lu's new artillery, from the marching state to the combat state, you only need to press the button, and the state can be switched in a few seconds.

The No. 01 black ribbon quickly climbed vertically through the clouds, but Li Zhan did not have the slightest intention of stopping the climb, but reported to the tower: "All systems are normal, the positive climbing rate is XXX per second, and it is still improving, over." ”

"Understand, Dong Qi pays close attention to the power system." Chen Ming reminded.

Li Zhan replied, "Understood." ”

Needless to say, any adaptive flight plan can be thrown away, and people will directly go up to the test mission. Otherwise, the old leader knew about Li Zhan, and Bao Guanhua was not surprised. Once this kid Li Zhan goes to the sky, it is not you who commands him, but he who commands you, and all the units on the ground have to follow his rhythm.

This is also the reason why he explained in advance to prepare for the test of several important technical performance.

Millions of old J-7s have allowed him to give hundreds of millions of luxury third-generation aircraft to the momentum, not to mention that he is now driving a fourth-generation aircraft.

After passing through the clouds, Li Zhan put down his goggles, and the visibility above and below the clouds was completely two. When the altitude reached 14,000 meters, he could still keenly feel the slight sensation of strong ultraviolet rays shining through the cockpit canopy on his hands, despite wearing his beloved white labor protection gloves.

The Air Force requires that the maximum ceiling of the fourth-generation aircraft be 1XXXX meters, and the R&D unit is developed according to a standard slightly higher than this indicator. However, it is not possible to fly to the required altitude, and the preconditions are very complicated.

For example, the ceiling is required to reach 18,000 meters, so what is the state of the fighter when it reaches this altitude is very critical. The maximum ceiling required by the troops is, of course, the maximum flight altitude that the fighter can achieve while still having combat capability. Wobbly flying is not good for the rope, no matter how high it is, what's the use.

To be more specific, how much combat capability will there be after reaching the ceiling, and in what areas will there be losses, etc., all by the test pilots.

Now the situation is much better, there are a large number of advanced monitoring instruments that can record massive amounts of data, which used to be all memorized by the pilot's brain. The first and second generation test pilots were distinguished by merit.

When it reached 15,000 meters, Li Zhan began to report every 100 meters he added, and at the same time reported the situation of each system of the fighter.

Generally speaking, most aircraft have no problem at this altitude, and the power will definitely be reduced. After being higher than the stratosphere, the air is thin and the resistance is small, but the oxygen content is also reduced, and the power of the general aero engine will be attenuated very much.

At this time, the advantages of the engine used in the fighter were reflected, with a larger compression ratio and a faster intake rate, slowing down the power decay. All the fighters that Li Zhan has flown have flown at an altitude of more than 15,000 meters, and at this time, he clearly felt that the power of the black ribbon has declined very little, and it is obvious that the engine is very powerful.

However, the R&D team made it clear that this model of engine is only for transition, and the engine specially developed for Black Ribbon is still in the critical stage, with more advanced performance, greater thrust, lower failure rate, longer life, and all in all, more hanging.

It's hard to imagine what kind of maneuverability the Black Ribbon would have achieved if it had been replaced with a matching engine. The ability of the black ribbon to adopt a canard pneumatic layout, Chengluoma factory through the development of J-10 to obtain a lot of experience and data, pneumatic fourth-generation aircraft project and then use several major aerodynamic layouts to do a lot of comparison, and finally decided to use the canard pneumatic layout.

It is obvious that the maneuverability and agility of the Black Ribbon are superior to the F-22A.

This is not self-congratulatory, the fact is that the F-22A was established in the seventies of the last century, the first flight was in 1997, and the first flight of the Black Ribbon was in 2012, which is a full fifteen years of time difference. The most important thing is that after entering the 21st century, especially around the year of the first flight of the Black Ribbon, China's avionics technology has advanced by leaps and bounds, and it has led the world in many technical aspects.

After a long period of use, which designs of the F-22A meet the requirements of modern warfare and which are underconsidered, the advantages and disadvantages have long been fully exposed.

The choice of aerodynamic shape also reflects the differentiation of the ideal of the modern battlefield trend, including the difference in specific national defense requirements. China pursues a defensive national defense policy, and the fighters that the Air Force wants are focused on air defense, and this can be seen from the emphasis of fighter planes in previous generations.

On the other hand, the black ribbon is larger than the F-22A, which fully demonstrates the character of the People's Air Force that likes to be big. This is also a mandatory requirement for national defense needs. Large range, large take-off weight, large speed, to achieve from any airport can take off to any airport in the territory within two hours.

When the advanced third-generation aircraft was introduced, the MiG-29 was seen at first, and the Soviet Union also strongly recommended the MiG-29, and later the Soviet Union collapsed, and the Russian side also strongly recommended the MiG-29, because at that time, the Mikoyan situation was very bad and he was in urgent need of funds.

But the People's Air Force was not interested in the short-legged MiG-29, but in the Su-27, a heavy fighter with excellent aerodynamic shape and a large range. It happened to coincide with the collapse of the Soviet Union, and the introduction of the Su-27 was also quite a setback.

J-10A is a special case, this is China's first completely independent research and development of the third generation aircraft, although it is a medium-sized fighter, the combat radius and maximum range do not meet the ideal requirements of the Air Force, but in any case must be vigorously supported.

Moreover, in the distribution of battlefield tasks, the J-10, which relies on the improvement of the ground air defense system, does not need to have the same range as the J-11. Another is that the follow-up air force gradually changed the main responsibilities of the J-10, from focusing on fighting for air supremacy to focusing on battlefield support, air cover, and ground combat capabilities.

To put it simply, the role of the J-10 is equivalent to that of the F-16 in the US Air Force.

Under the excellent aerodynamic shape and powerful thrust, the No. 01 Black Ribbon reached an altitude of 17,000 meters in one go. Looking down at this height, you will see a huge ball, mostly blue, with a glow on the rim.

It turns out that the earth is round!

Li Zhan continued to report the latest data, the ground testing equipment has been tracking and measuring the No. 01 black ribbon, all kinds of data are summarized to the tower, and the technicians are busy recording and analyzing, and a specific index has turned green, which means that these indicators have withstood the test in another test and met the requirements.

“1XX！ All systems are normal! Li Zhan once again reported the latest data.

For the sake of conciseness of the call, 100 meters is used as a unit, and you only need to report the first three digits of the ground to know the specific height.

Li Zhan observed the speed of the engine, and after reporting the data again, he said, "The power of the two engines has decreased by X percent, and the climb rate has decreased significantly." ”

Chen Ming asked, "What is the situation of each system?" ”

"Normal, the plane is stable." Li Zhan replied.

Chen Ming reminded, "Dong Yu, you are about to approach the latest altitude measured by the ceiling, pay close attention to the situation of the aircraft." ”

"Understood."

Everyone in the tower held their breath. There is a set of data on the display screen that is very conspicuous, the right side of the diagonal line used to separate is the maximum height that flew out last time, and the left side is the altitude data that Li Zhan has reached now, the number is constantly rising, and it seems that the maximum height reached last time is in an instant.

Chen Ming asked in a low voice, "Leader, do you want to consider level flight, Dong Yu has been climbing vertically, and I'm worried that there will be problems with the engine." ”

"No, he knows it." Bao Guanhua shook his head and said.

Chen Ming nodded slightly, wanting to pick up the telescope to look, but when he saw the thick clouds, he immediately dispelled his thoughts, and could only stare at the small aircraft logo representing the No. 01 black ribbon on the display screen.

When the two sets of data were completely consistent, Li Zhan's report came at the same time, "The altitude is 1XX, the various systems of the aircraft are normal, and the power attenuation is a little great." ”

"It's more than a hundred meters beyond the previous data, what do you think about it? Will level flight be resumed? Chen Ming said.

Li Zhan said, "Keep a vertical climbing posture, and I'll see where the limit of the black ribbon is." ”

The crowd's eyebrows fluttered, this is the technician, and then there are some people with complicated expressions and more worries, this is wearing military uniforms.

"Agreed!"

Bao Guanhua picked up the microphone and approved Li Zhan's plan.

No. 01 Black Ribbon continues to climb vertically with its head held high!
