As we all know, the wind in the eye of the typhoon is very small, the weather is clear, and the diameter is dozens of kilometers, and the strongest part of the typhoon circle is the cloud wall area where the eye wall extends outward for tens of kilometers or even hundreds of kilometers. The wind is declining from the inside out, and this range is the windiest area of the typhoon circle and the worst weather, and the tumbling clouds rotate around the eye of the wind to form a cloud wall that is even more than 10,000 meters high.

According to the drop value of the left thrust, Li Zhan quickly calculated that when the fighter plane that was decelerating the movement arrived at the meeting point, the outer part of the cloud wall area of the typhoon also happened to affect the meeting point. Not a point, exactly, but an airspace with a diameter of tens of kilometers.

The fighter will not stall, even if the left engine is completely scrapped and the right engine is still able to provide enough power for the fighter to keep flying. The problem is that the fighter will not be able to fly back, but will keep turning to the left and circling, and then be stirred in the cloud wall area, and the consequences will be unimaginable.

Any mechanical failure of a prototype can be forgiven, and there are differences between fighters produced by the same fighter and the same production line, let alone a fighter that has not yet been finalized.

To put it another way, it would be better if all the problems were exposed at the test flight stage rather than after the delivery to the troops.

However, the problem Li Zhan encountered at the moment was not only the problem of the fighter itself, but the external objective threat brought about by the failure of the fighter - it was completely possible to quickly get out of the threatened airspace before the typhoon cloud wall area was covered.

Chen Fei was already making preparations before abandoning the plane, sorting out all the materials and putting them in the pocket of the flight suit, once the plane was abandoned, these top-secret materials should be carried with him, and if necessary, they should be completely destroyed. Li Zhan was also preparing, and it was impossible for him to stop the plane and overhaul the left engine, so he could only plan for the worst.

However, he was looking for the best crash location according to the aeronautical charts - under a controlled situation, the pilot had to try to choose the most convenient location for our military to carry out follow-up processing, and to ensure that top-secret equipment such as friend or foe identifiers were completely destroyed.

This is above the high seas, and below it is an international shipping line, so it is necessary to take appropriate measures.

Li Zhan had to put the right hand in the slow train position, and watched the airspeed drop to 280 kilometers per hour, which was almost the take-off speed. When the number of the airspeed stopped falling, Li Zhan was stunned for a moment, and subconsciously said, "Stabilize it, stabilize it, stabilize the speed." ”

Chen Fei also noticed this positive change, and he said happily, "Can you try to increase the thrust?" The oil supply system should not fail completely. ”

After realizing that there was a problem with the fuel supply to the left engine, Li Zhan reduced the supply pressure of the left engine, which could prevent the fuel injected into the engine's combustion chamber from surging due to incomplete combustion. The choice of detail reflects the pilot's experience, and logically when it is found that the engine is not supplying enough fuel, it is necessary to try to increase the pressure, that is, to throttle deeper, but in practice this usually leads to more serious disasters.

If the oil supply is insufficient due to the rupture of the oil circuit, the afterburner supply pressure will exacerbate the situation, which will eventually lead to the entire oil circuit rupture or even cause an engine fire. In either case, the consequences are worse than underfueling, where the engine has at least thrust.

It is precisely because of his rich experience in handling dangerous situations that Li Zhan was able to carry out the most timely and correct operation at the first time when the problem occurred. In the conversation with Fu Zhi, it seems to be a leisurely walk, giving people the feeling of being rubbed a little bit of paint and a little accident, but in the process of reporting, Li Zhan has already completed the due manipulation action.

The commander on duty looked at the red dot on the radar display, which represented "Wuyi Mountain," flying westward at a speed of 280 kilometers per hour, while the other display showed a real-time weather cloud map, and the edge of the typhoon circle had swept to "Wuyi Mountain."

The commander on duty called Li Zhan with a solemn expression, "Wuyi Mountain, you have entered the periphery of the Cloud Wall District, pay attention to the changes in the airflow, you are three hundred kilometers away from the coastline, can you adjust the course to 360?" ”

360 degrees is true north.

Li Zhan replied, "I'm afraid I can't do it, my right hair can only keep slow, the plane can barely maintain its course, I can't move anything now, it's over." ”

"Prepare for abandonment, do you understand?" The commander on duty received instructions from the duty room of the air division and gave clear instructions to "Wuyishan" very decisively.

Li Zhan said, "We've prepared for the worst, and we're done." ”

A few minutes later, the duty room of the military region activated the emergency plan, and the search and rescue units on both the sea and air routes received orders, and the maritime search and rescue detachment immediately began to move in the direction where "Wuyi Mountain" was located. You must know that they are going to brave the threat of a typhoon to sail to the typhoon area, so that once the "Wuyishan" abandons the plane, they can rescue the two pilots in the shortest possible time.

At this moment, a meteorological staff officer ran over and reported to the commander on duty: "Report! The local meteorological department issued an orange warning signal for the typhoon, and the typhoon name was also confirmed, called Sana, which is likely to affect the southeast of our country in the next 12 hours, and the central wind is expected to reach level 15. ”

"I'm really afraid of something." The look of the commander on duty became even more solemn.

A few hours ago, everything was not very bad, and even according to the analysis of the clouds at that time, it may have been a small typhoon of twelve or three levels, and the wind will weaken after landfall, and a ten-level and eleventh gust is considered good, but I didn't expect such a big change in just a few hours.

However, this is a common occurrence for them stationed in the southeast region, and the fourteen or fifteen typhoons are at most strong typhoons, and the wind strength of no seventeen or eighteen is not enough for people in the southeast to face up.

If it weren't for the fact that Typhoon Sana was moving at a speed of only 50 kilometers per hour, "Wuyi Mountain" would definitely be more than auspicious. At present, "Wuyi Mountain" still has an airspeed of at least more than 280 kilometers per hour, and the direction and course are somewhat offset, but it always runs faster than "Sana".

However, this is already a threat to "Wuyi Mountain".

Li Zhan felt that the attitude of the fighter plane was becoming more and more uncontrollable, and the whole plane was shaking up and down, left and right, and it was a strong and chaotic air flow that was at work.

The most terrible thing is that the centripetal force is increasing - as if a big hand is grabbing the fighter and slowly dragging it into the eye of the wind.

Li Zhan couldn't help but say, "I entered the Cloud Wall Area, the centripetal force is very strong, it doesn't look like a small typhoon in the eleventh or second year at all, Fu Zhi, has the weather report been updated?" Complete. ”

The commander on duty here was about to report the latest weather conditions, and when he heard this, he immediately said, "Wuyi Mountain, the weather has changed a lot. Under the influence of strong convection, the typhoon has developed again, and the local meteorological department has officially identified it as this year's No. 1 typhoon signal, named Sana, and the central wind force has reached level 15, so you have to find a way to get out of the cloud wall area, over. ”

Li Zhan didn't panic, and asked again, "Has Sana's direction of movement changed?" Is there a more accurate prediction? I'm afraid I won't have a chance to see the coastline if I fly like this, over. ”

"There is no data on this for the time being, be ready to parachute at any time, and the maritime search and rescue team has already set off." The commander on duty said.

"Understood."

Li Zhan took a deep breath of oxygen and said, "I have to go down to three thousand meters." ”

The commander on duty was taken aback and said, "Then you don't have much leeway, you only have two hundred and eight airspeeds now." ”

The more you maintain altitude when your airspeed is insufficient, the farther you can glide in the worst-case scenario, and the closer you are to the shoreline, the better your chances of being rescued. Don't think you can survive if you parachute, but the sea is 300 kilometers from the coastline below, and it's a dark and sloppy early morning, so you can't feed the sharks.

"But the three-kilometer airflow is relatively stable." Li Zhan said.

The situation is relatively better in the airspace layer of 3,000 to 4,000 meters in the cloud wall area, the airflow is relatively stable, and the crosswind is relatively small. The most powerful are the upper and lower parts of the Cloud Wall area, where the plane is like pork in a blender.

Fu Zhi's on-duty commander finally approved Li Zhan's request.
