There are so many cameras deployed at so many angles throughout the outfield that no situation in the Black Ribbon can escape surveillance, no matter how small anomaly it is.
After moving his hands and feet for more than ten minutes, the tower gave Li Zhan permission to roll on the ground.
Li Zhan pushed the throttle lever to the half-throttle position, and the two new turbofan engines instantly sprayed out hot blue tail flames. It is obvious that the Black Ribbon has the ability to cruise at supersonic speeds without turning on afterburner. This is also the fourth
One of the hallmark features of modern machines.
The two engines burst out with powerful thrust, and the engine speed increased very quickly. Li Zhan had already felt this strongly when he was testing the car on the ground. When he released the brakes, he felt even more profoundly.
It is very, very textured and accelerates very quickly, but it is not as fast as a light one, but like the acceleration of a large-displacement naturally aspirated D-class car, and the speed goes up unconsciously. It is a bit like the J-11 series and
The J-15 is obviously different from the J-10 series.
The sudden lift of the plane's nose was absolutely stunning.
As the saying goes, when the black ribbon raises its head, everyone must bow its head.
The runway was relatively long, and Li Zhan calculated the distance to leave enough space for deceleration. He noticed that the black ribbon only needed a runway length of just over 300 meters to reach take-off speed. If the afterburner was turned on, it would definitely be able to run within 300 meters. In this way
The results are definitely second to none in the world.
When decelerating, the full-motion canards and full-motion twin vertical tails can provide strong braking force, thus giving a very eye-catching deceleration distance. Li Zhan was immersed in shock while returning to the take-off position along the taxiway.
middle.
He even imagined that if the ground support could keep up, the take-off and landing performance of the Black Ribbon could be deployed at front-line airports. There would be no need for a long runway. Three to five hundred meters would be enough. Some two-way six-lane, eight-lane
Lane expressways 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 it is covered with stealth paint, it will have to undergo complex support every time it flies, which will definitely kill the maintenance team.
pressure.
Various countries have made frontline fighter aircraft durable and tried their best to simplify maintenance procedures. This is precisely because the environment of frontline airports is usually very harsh and there is no even paved runway. In our military sequence, there are only about Q-5 fighters among them.
This low-key and luxurious attack aircraft has the ability to take off and land at field airports.
The Q-5 is said to be low-key and luxurious because the old man dropped a nuclear bomb and shouldered the heavy responsibility of aerial nuclear strikes for a long time. Later, after the H-6 was modified, the old Q-5 was relieved of this heavy responsibility.
After three consecutive slides, Li Zhan basically found the feeling.
The time reached 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 take charge of the specific command, so of course Chen Ming sat on the main command seat without mercy, and Bao Guanhua sat on the deputy commander's seat.
Chen Ming picked up the red transmitter and said, "Dongyao, get ready to take off."
"I understand, you can take off." Li Zhan put on his oxygen mask. Because the sky was gray, he didn't put down his goggles.
He hit the control stick again to check each controllable airfoil, and then stepped on the brakes. The throttle lever was fully turned on afterburner, and the speed suddenly surged. The speed surprised Li Zhan. He quickly let go
Braking, the nose of the Black Ribbon aircraft suddenly lifted, and then it ran wildly.
After taxiing for more than 200 meters, Li Zhan gently pulled up the nose of the plane and then quickly leveled it while retracting the landing gear. The black ribbon flew close to the ground at a height of about five meters from the runway, like a ghost. On the tower
Everyone was stunned.
Everyone knows that Li Zhan is a fierce man, but they didn’t know that he was so fierce!
The person who stopped and waited for the entire test flight was obviously an expert. The problem was that the performance of this expert far exceeded their expectations. Although they had tried very hard to use their imagination, it seemed that they were far from the reality of this expert.
There is still a long way to go in flight technology.
"What a fierce man!" Chen Ming couldn't help but sigh, "I was a teacher for him, but he was just as good as a teacher for me."
No one has flown this kind of takeoff before.
More exciting things are coming.
The Black Ribbon hadn't flown even one kilometer when Li Zhan suddenly yanked the nose of the aircraft. The Black Ribbon suddenly tilted back ninety degrees, drawing an arc of ninety degrees at ultra-low altitude, and then roared at extremely fast speeds.
Speed climbs vertically.
"This is the real onion pulling on dry land!" Chen Ming marveled.
Don't think that this is a take-off method that is only for performance. Make full use of the agility and super maneuverability of the fighter plane to leave the runway in the shortest time, gain altitude in the shortest time, and enter combat status in the shortest time.
Just like Lao Lu's new artillery, from marching state to combat state, you only need to press the button, and the state switching can be completed in a few seconds.
Black Ribbon No. 01 quickly climbed vertically through the clouds, but Li Zhan had no intention of stopping the climb. Instead, he reported to the tower: "All systems are normal, the positive climb rate is XXX per second, and it is still improving. Complete."
"Understood, Dongyao pays close attention to the power system." Chen Ming reminded.
Li Zhan replied, "Understood."
Needless to say, all the adaptive flight plans can be thrown away, and they will directly go to the upper limit test mission. Otherwise, the old leader knows Li Zhan, so Bao Guanhua will not be surprised. Once this kid Li Zhan is on
In the end, it is not you who commands him, but he who commands you, and all units on the ground have to follow his rhythm.
This is also the reason why he made preparations in advance to test several important technical performance.
The old J-7 cost several million, but he has the momentum to fly a luxury third-generation aircraft worth hundreds of millions, let alone a fourth-generation aircraft now.
After passing through the clouds, Li Zhan put down his goggles. The visibility above and below the clouds was completely different. When the altitude reached 14,000 meters, even though he was wearing his beloved white labor protection gloves, he could still see
I keenly felt the slight sensation of strong ultraviolet rays shining through the cockpit cover on my hands.
The Air Force requires that the maximum ceiling of the fourth-generation aircraft is 1XXXX meters, and the research and development unit develops it according to a standard slightly higher than this indicator. However, it does not mean that it can fly to the required height, and the preconditions are very complicated.
For example, if the ceiling is required to reach 18,000 meters, then the state of the fighter aircraft when it reaches this altitude is very critical. The maximum ceiling required by the army is naturally the maximum flight altitude that the fighter aircraft can reach while still having combat capabilities. Shake it.
It's so dangling that it's not easy to fly, so what's the use of flying high.
To be more specific, it is how much combat capability is left after reaching the service limit, and in what aspects it will be lost, etc., etc., all of which depend on test pilots to fly it.
The situation is much better now. There are a large number of advanced monitoring instruments that can record massive amounts of data. In the past, it was all up to the pilots to memorize it in their heads. The first and second generation test pilots have outstanding merits.
When it reached 15,000 meters, Li Zhan began to report every 100 meters, and at the same time reported the status of each system of the fighter plane.
Generally speaking, most aircraft will have no problems at this altitude, but the power will definitely decline. 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 ordinary aero engines will decline very much.
sharp.
At this time, the advantages of the engine used by fighter jets are reflected. A larger compression ratio and faster air intake speed slow down the power decline. All the fighter jets Li Zhan has flown have flown over an altitude of more than 15,000 meters. At this time,
It is obvious that the Black Ribbon has very little power degradation, and it is obvious that the engine is very powerful.
However, the R&D team made it clear that this type of engine is only for transition. The engine specially developed for Black Ribbon is still in the critical stage. It has more advanced performance, greater thrust, lower failure rate, longer life, and is generally more stable.
It’s hard to imagine what kind of maneuverability the Black Ribbon will achieve if it is replaced with a matching engine. The Black Ribbon uses a canard aerodynamic layout, and the Chengdu Lockheed Martin Factory has gained a lot of experience and data through the development of the J-10.
, after the fourth-generation pneumatic engine project, a large number of comparisons were made with several main aerodynamic layouts, and the canard aerodynamic layout was finally decided.
Obviously, the Black Ribbon's maneuverability and agility are superior to the F-22A.
This is not self-indulgence. The fact is that the F-22A project was established in the 1970s. The first flight was in 1997, while the first flight of the Black Ribbon was in 2012. There is a time difference of fifteen years.
The most important thing is that after entering the 21st century, especially around the time 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.
The Black Ribbon, which has the advantage of being a latecomer, has the F-22A as a reference that can be used to cross the river. After long-term use, which designs of the F-22A meet the requirements of modern warfare and which ones are not considered? The advantages and disadvantages are
It has already been fully exposed.
The choice of aerodynamic shape also reflects the ideal differentiation of modern battlefield trends, including differences in specific national defense requirements. Our country pursues a defensive national defense policy, and the fighter jets required by the Air Force focus on air defense. This
This can be seen from the focus of fighter jets in the past.
On the other hand, the Black Ribbon is a circle larger than the F-22A, which fully shows that the People's Air Force likes to be big. This is also a rigid requirement put forward by national defense needs. Large range, large take-off weight, and high speed can achieve anything from any
Taking off from any airport, you can arrive at any airport in the country within two hours.
When the advanced third-generation aircraft were introduced, the first one they looked at was the MiG-29. The Soviet Union also strongly recommended the MiG-29. Later, after the Soviet Union disintegrated, the Russian side also strongly recommended the MiG-29 because Mikoyan's situation was very serious at that time.
It's not good and we need funds urgently.
However, the People's Air Force has no interest in the short-legged MiG-29. Instead, it has a strong interest in the Su-27, a heavy fighter with excellent aerodynamic shape and long range. It happened to coincide with the disintegration of the Soviet Union, and there were many Su-27s introduced at the beginning.
frustration.
The J-10A is a special case. It is my country's first third-generation aircraft that is completely independently developed. Although it is a medium-sized fighter, its combat radius and maximum range cannot meet the ideal requirements of the Air Force, but it must be strongly supported no matter what.
Moreover, in terms of the distribution of battlefield tasks, the J-10, which relies on a complete ground air defense system, does not need to have the same range as the J-11. Another is that the subsequent Air Force gradually changed the main responsibilities of the J-10, from focusing on
After fighting for air supremacy and focusing on battlefield support, air cover, and ground combat capabilities, the multi-purpose C type was developed after the B type was used in small batches.
Simply put, the role of the J-10 is equivalent to the role of the F-16 in the US Air Force.
With its excellent aerodynamic shape and powerful thrust, the No. 01 Black Ribbon reached an altitude of 17,000 meters in one breath. Looking down at this height, you will see a huge ball, which is mostly blue.
, the edge of the ball is still glowing.
It turns out that the earth is round!
Li Zhan kept reporting the latest data. The detection equipment on the ground kept tracking and measuring the No. 01 black ribbon. All kinds of data were summarized at the tower. The technicians were busy recording and analyzing. Each specific indicator became
Turning green means that these indicators have withstood the test and met the requirements in another test.
"1XX! All systems are normal!" Li Zhan once again reported the latest data.
To simplify the call, hundreds of meters are used as the unit. You only need to report the first three digits of the ground to know the specific height.
Li Zhan observed the engine speed, reported the data again, and said, "The power of the two engines has been reduced by X percent, and the climb rate has dropped significantly."
Chen Ming asked, "How are the various systems?"
"Normal, the plane is very stable." Li Zhan replied.
Chen Ming reminded, "Dongyao, you are about to approach the latest measured altitude of the ceiling. Pay close attention to the aircraft's condition."
"clear."
Everyone on the tower held their breath. There was a set of data on the display screen that was very conspicuous. The right side of the diagonal line used for separation was the maximum altitude he flew out last time, and the left side was the altitude data Li Zhan had reached now. The numbers
It was constantly rising and reached the maximum height in an instant.
Chen Ming asked for instructions in a low voice, "Leader, are you considering level flight? Dongyao has been climbing vertically. I'm worried that there is something wrong with the engine."
"No need, he knows it well." Bao Guanhua shook his head and said.
Chen Ming nodded slightly and wanted to pick up the telescope to look, but when he saw the thick clouds, he gave up the idea and could only stare at the small aircraft logo with the black ribbon representing No. 01 on the display.
When the two sets of data were completely consistent, Li Zhan's report came at the same time, "Altitude 1XX, all systems of the aircraft are normal, but the power attenuation is somewhat severe."
"It has exceeded the previous data by more than 100 meters. What do you think about it? Should we resume level flight?" Chen Ming said.
Li Zhan said, "Keep climbing vertically and let me see where the black ribbon's limit is."
Everyone was beaming, they were technicians, and some people looked complicated and worried, they were in military uniforms.
"agree!"
Bao Guanhua picked up the microphone and approved Li Zhan's plan.
Black Ribbon No. 01 continues to climb vertically with its head held high!
