Chapter 664 When the Black Ribbon Raises Its Head

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 approved Li Zhan 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 was obvious that the Black Ribbon had the ability to cruise at supersonic speeds without turning on afterburner. This is also one of the hallmark features of the fourth-generation machine.

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

It's very, very textured and accelerates very quickly, but it's not that light and fast, 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, and 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 room 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 reach 300 meters. Such achievements are definitely second to none in the world.

When decelerating, the full-moving canards and full-moving double vertical tails can provide powerful braking force, thus giving a very eye-catching deceleration distance. Li Zhan was immersed in shock as he returned to the take-off position along the taxiway.

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. It would not require a long runway, and three to five hundred meters would be enough. Some two-way six-lane, 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 it is coated with stealth paint, it will have to undergo complex safeguards every time it flies. It will definitely be a life-threatening pressure for the maintenance team.

Various countries have made their frontline fighter jets durable and tried their best to simplify maintenance procedures. This is precisely because frontline airports usually have very harsh environments and do not even have paved runways. Among the fighters in our military, only the Qiang-5, a 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 has dropped nuclear bombs and has shouldered the heavy responsibility of aerial nuclear strikes for a long time. Later, after the H-6 was modified, the old Qiang-5 was relieved of this heavy burden.

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."

"Dongyao understands, you can take off." Li Zhan put on his oxygen mask. Because the sky was gray, he did not put down his goggles.

He hit the control stick again to check each controllable airfoil, and then stepped on the brakes. The accelerator lever turned on the afterburner, and the speed suddenly shot up. Li Zhan was slightly surprised by the speed. He quickly released the brakes, raised the Black Ribbon nose suddenly, and then ran out.

After taxiing for more than 200 meters, Li Zhan gently pulled up the nose of the plane and 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. All the people on the tower were 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 flying technology.

"What a fierce man!" Chen Ming couldn't help but sigh, "I was still 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 had not flown 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 performance-only way to take off. 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: "Every system is 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 adaptive flight plans can be thrown away, and they can directly go to the upper limit test mission. Otherwise, Bao Guanhua would not be surprised if the old leader understood Li Zhan. Once Li Zhan goes up to the sky, you will not be commanding him but he will be commanding you, and all units on the ground will have to follow his lead.

This is also the reason why he made preparations in advance to test several important technical performance.

The old J-7 costing several millions gave him the momentum to fly a luxury third-generation aircraft costing hundreds of millions, let alone the fourth-generation aircraft he is now flying.

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 favorite white labor protection gloves, he could still keenly feel the strong ultraviolet light shining on his hands through the cockpit cover.

The Air Force requires the maximum ceiling of the fourth-generation aircraft to be 1XXXX meters, and the research and development unit develops it according to a standard slightly higher than this indicator. But it's not just about flying to the required height. 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 troops is naturally the maximum flight altitude that the fighter aircraft can reach while still having combat capabilities. It's useless to fly too high if it's shaky.

To be more specific, it is how much combat capability is left after reaching the ceiling, and in what aspects it will be lost, etc., etc., it all depends on the test pilot 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, pilots had to rely on their brains to record data. The first and second generation test pilots were meritorious.

When he 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 decrease. After being higher than the stratosphere, the thin air has less resistance but the oxygen content is also reduced, and the power of ordinary aeroengines will be severely attenuated.

At this time, the advantages of the engine used in fighter jets are reflected. A larger compression ratio and faster air intake speed slow down the power decline. All the fighter planes Li Zhan had flown had flown at an altitude of more than 15,000 meters. At this time, he could clearly feel that the Black Ribbon's power had declined very little. It was obvious that the engine was 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 reliable.

It’s hard to imagine what level the Black Ribbon’s maneuverability will reach if it is replaced with a matching engine. The original Black Ribbon adopts a canard aerodynamic layout. The Chengdu Luoma Factory gained a lot of experience and data through the development of the J-10. After the fourth-generation aerodynamic aircraft project, it made a lot of comparisons with several major aerodynamic layouts, and finally decided to use the canard. pneumatic layout.

Obviously, the Black Ribbon is more maneuverable and agility than the F-22A.

This is not self-pleasure. 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 Black Ribbon's first flight, 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 can be seen from the focus of fighter jets in previous generations.

On the other hand, the black ribbon is one 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 imposed by national defense needs. With its large range, large take-off weight and high speed, it can take off from any airport and arrive at any airport in the country within two hours.

When the advanced third-generation aircraft were first introduced, they initially looked at 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. Coinciding with the disintegration of the Soviet Union, the initial introduction of the Su-27 also faced many setbacks.

The J-10A is a special case. This 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 to operate, does not need to have the same range as the J-11. Another is that the Air Force has gradually changed the main responsibilities of the J-10, from focusing on fighting for air supremacy to focusing on battlefield support and air cover, as well as ground combat capabilities. After the B-type was used in small batches, it came up with many Type C for use.

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. If you look down at this height, you will see a huge ball. Most of the ball is blue, and the edges of the ball are glowing.

It turns out that the earth is round!

Li Zhan continued to report the latest data. The detection equipment on the ground has been tracking and measuring the No. 01 black ribbon. All kinds of data are summarized at the tower. The technicians are busy recording and analyzing, and each specific indicator has become 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 situation of the aircraft."

"clear."

Everyone on the tower held their breath. There is a set of data that is very conspicuous on the display screen. The right side of the dividing line is the maximum height he flew out last time, and the left side is the height data Li Zhan has reached now. The numbers are constantly rising. Seeing that he has reached the last time, The maximum height is within 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 about engine problems."

"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 then there were some people who looked complicated and worried, they were people 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!
