"Doodle, doot, dood......"

The Posture Awareness Warning System is chirping, and the Battlefield Situational Awareness System is also issuing a warning.

A strong crosswind overturned the No. 01 black silk ground, and the plane turned sideways a few times, and then the nose of the plane fell sharply, and Li Zhan held the joystick hard and kicked the rudder. He didn't rush to pull the rod and raise the nose of the plane, the airspeed was too fast, and a little big action would cause a super overload, and the plane would be in danger of disintegrating in the air.

He could only fly in the direction of the nose first, and then slowly change the direction of the nose. When the nose of the fuselage fell down just now, the fuselage was already making a "crunch" sound. You know, this is a supersonic speed of 1880 kilometers per hour!

Another rapid alarm sounded, and Li Zhan quickly saw that a strong radar reflection signal appeared in front of him, and it was a peak.

He didn't care much more, and in just two seconds, he used all the deceleration methods except the parachute, pulling the lever back hard to lift the nose, and at the same time risking increasing the angle of the left turn!

All of this is moving in the direction of disintegration in the air.

Instead of crashing into a mountain and dying, it is better to be cut into parts in the air with the beloved No. 01 black ribbon.

It was not difficult to make such a choice, and from the first day of the flight, he was ready to sacrifice his life at any time, without which he would not have been able to withstand so many dangerous encounters. It was his ideal to dedicate his life's energy and even his life to the cause of national defense.

Li Zhan's efforts were limited.

The airspeed of the aircraft is too fast, the various deceleration methods are not very effective, the effect of turning and raising the nose is not good, and the inertia of the aircraft forward in supersonic conditions is too great. Although Li Zhan had done his best, and he was even eager to scrap the telex system, the plane's attitude of flying diagonally downward and rapidly did not change much.

The ground-based surveillance radar suddenly lost the signal of the No. 01 black ribbon.

Chen Ming's heart sank when he saw it, and Bao Guanhua couldn't calm down when he saw it, and his fists were clenched. The others even stopped what they were doing and stood up to stare at the radar display.

"Dong Mi, hear the reply, Dong Mi!" Chen Ming called.

Black Ribbon 01 did not reply because the communication system was out of order. Although Li Zhan was able to determine that the control system was not malfunctioning, he also vaguely felt that the plane's response was somewhat sluggish.

There is a chain reaction, which is a very dangerous signal.

Li Zhan didn't even have time to activate the backup system, and by this time the plane had already crashed into the mountains, and many towering peaks blocked the radar detection signal with the height dropping sharply. After entering the mountain, civilian airliners are generally not allowed to descend to an altitude of less than 6,000 meters, and usually need to fly above 8,000 meters.

The No. 01 black ribbon seemed to be in the cumulonimbus clouds that could never fly, and Li Zhan could not see the situation outside, and could only judge the situation based on the attitude and flight data of the aircraft. From the sudden change to the collision with the mountain, Li Zhan only has a maximum of three seconds at most.

In those three seconds, he completed more than a dozen maneuvers, and the No. 01 black ribbon slid sideways to meet the mountain, and the sudden increase in air resistance caused the airspeed to drop suddenly. Li Zhan could only do this at the risk of the disintegration of the plane, and at this time, he didn't care about whether the engine would be scrapped because of this.

Of the four situations that the engine is most afraid of, the large sideslip is in the front. In order to maintain airspeed, the engine must continue to work, and finally enter a high-load state.

The airspeed dropped to subsonic speed in an instant, the wings of the fuselage made a very harsh sound, the attitude of the plane was finally contained, and in order to slow down he even released the landing gear!

In the end, the landing gear of the No. 01 Black Ribbon brushed the trees on the mountain for a while, the belly of the plane was towards the mountain, and the fuselage was tilted 90 degrees and flew out of a parallel line relative to the mountain peak - the mountain collision crisis was temporarily lifted.

At this time, Li Zhan bit Bai Sensen's teeth, and he didn't do anything, but he simply took the risk to the end. Because he knew very well that he was in the dense fog in the mountains at this time, and the radar anti-collision warning had been sounding, indicating that there must be various obstacles ahead, and the terrain in this area was much more complicated than that of the Beiku Mountains!

He released the parachute.

The huge drag once again lowered the airspeed, and then the parachute quickly disconnected itself under the huge traction force, drifting back farther and farther. The airspeed of the plane plummeted to more than 600 kilometers per hour at this time, allowing Li Zhan to gain more reaction time.

Do your best to avoid obstacles in front of you while constantly pulling the rod backwards, the most important thing at this time is to climb the height, and be sure to completely eliminate the danger of hitting the mountain. Piloting a plane with a serious malfunction in the dense fog in the mountains, let alone a forced landing on the return flight, it is a question of whether it can get out of the mountain.

However, the situation did not change according to Li Zhan's will, although the flight control system was a little sluggish, the aircraft was still controllable, and the most terrible thing was that the situation of the power system was very bad - the thrust continued to increase.

This illustrates the brutal fact that the powertrain was not affected by a few large overload maneuvers just now, and it was neither back to normal nor worse because of it. At the same time, the rigid structure of the fuselage of the aircraft was severely tested, and the plane survived, which was obviously an unexpected bonus.

As a result, Li Zhan was strongly aware that he had to do his best to ensure the safety of the aircraft, and when the communication system failed, the communication between the monitoring equipment on the plane and the ground was also affected. Flight data and aircraft status data are automatically stored and need to be returned to the ground for export.

If the plane falls, then there is a danger that this valuable data will be lost. How important is data? It can be said that there will be no opportunity to obtain such data in the future. What the plane experienced and endured at that moment during a large overload maneuver at supersonic speeds can only be analyzed through the data at that time.

No one will be able to fly the same maneuver.

It is simply impossible for such a maneuver to fly out on the initiative of the pilot, and only under the influence of several extremely rare factors, such a situation will occur in the aircraft.

Li Zhan had no choice but to shuttle among the mountains. What made him somewhat sure was that the reaction speed of the airborne radar flew out quickly, but there will be a process in the process of detecting any radar, and the process of transmitting radar waves and receiving echoes will be processed. The most flexible airborne radar Li Zhan has used is the AESA radar on the J-10B, that is, the active phased array radar, and the larger diameter AESA radar on the J-16.

But neither of the above radars is comparable to the No. 01 Black Ribbon airborne radar, a very advanced active phased array radar of an unknown model. It often only takes half a second for Li Zhan to get feedback through the on-board radar, and he can have more time to maneuver accordingly.

Thanks to the No. 01 Black Ribbon, it is a complete prototype, that is to say, the state of the aircraft is to be delivered to the troops, and generally some prototypes are not immediately equipped with airborne radar, and they are slowly improved with the progress of the test flight.

In addition to the airborne radar, the fuselage of the No. 01 black ribbon is integrated with various sensors to form a battlefield situational awareness system, such as infrared detection and wireless signal detection, which is very powerful. This battlefield situational awareness system fed back a large amount of rich information, which played a very big role in Li Zhan's understanding of the external situation.

Some test pilots say that the fourth-generation aircraft is an aircraft that can be piloted by blind people, although it is an exaggeration, but it reflects the extremely strong situational awareness of the fourth-generation aircraft. Pilots obtain the battlefield situation through their eyes, but the ability of human eyes to obtain is limited, and the ability to process information is also limited, and super situational awareness is an important feature of fourth-generation aircraft.

The four characteristics of the fourth-generation aircraft are summed up as four "S", super-maneuverability, supersonic cruise, stealth, and super battlefield situational awareness, and the first letter is "S", so it is called -35, Rafale, J-10C, J-16, etc. The reason why they are called three and a half generations is because they have some capabilities, such as Su-35 has super-maneuverable capabilities, and the avionics systems of J-10C and J-16 use a lot of black ribbon technology.

Many people think that the J-16 is generalized, and the appearance has not changed much, and it looks no different from the J-11 and Su-30, and even many people can't tell by the appearance. But the J-16's avionics system is very awesome, and it is the most powerful in the J-11 family.

The J-16 was put into service later than the J-20, so many military fans have considerable opinions about the Shen Hoy Factory, thinking that the Shen Hoy Factory has not made any progress except for gnawing old bones. What is the real reason, that is, major surgery was performed on the internal avionics system, and a large number of J-20 avionics technology was used, which is quite powerful.

With the help of the black ribbon's super perception of the external environment, Li Zhan was still able to react very quickly and effectively despite being trapped in a dense fog.

The reward of practicing flying through the mountains in Beiku has come. Flying the J-7EG in the bend and fog of the Beiku Canyon for ultra-low-altitude traversal, a round trip of hundreds of kilometers, and often in complex meteorological conditions for the same standard of training.

Without this ability, he really didn't dare to be the main test pilot of the fourth-generation aircraft.

Unable to increase his flight altitude, Li Zhan could only fly in the mountains, dodging left and right to avoid the towering peaks, while seizing every opportunity to turn eastward counterclockwise. Only by turning to the east will it be possible to fly out of the mountains in the shortest possible time.

He has a very good habit of memorizing charts, meteorological maps and climatic characteristics of various regions, so he is very familiar with the topography of this plateau area. When I was in Beiku, I often ran this way to engage in long-distance flight training.

After adapting to it, Li Zhan breathed a little empty, as long as the control stick was not broken, he was sure to drive the plane back, and of course he needed power.

He breathed a sigh of relief, but the people on the ground went crazy.

PS: I will make up for it one after another, and at the same time start preparing a new book, which will be quite an interesting new work.
