As Yang Luo's voice sounded, warm applause suddenly erupted in the tower monitoring room.

The rumored 145 kilometers per hour really reached, turning the rumor into reality.

Chief Secretary Wang couldn't help but smile on his face and said with great satisfaction: "Okay, keep a speed of 145 kilometers per hour for twenty seconds, and then change to return."

Yang Luo was about to respond, but suddenly an idea came up. What would it be like if the angle of attack limit is contacted and the angle of attack is increased by 0.1 degree? Is it really a stall?

So Yang Luo said, "Tower, I want to lift the angle of attack restrictions and try it?"

"No, it will stall if it is." Chief Secretary Wang vetoed.

Yang Luo argued reasonably: "My current height is five thousand meters, and even if it is stalled, there is no danger. Let me try the tower."

Chief Secretary Wang turned to look at the major general beside him and asked, "What do you mean?"

The major general thought for a while and said, "No one has done such an experiment, and the altitude of 5,000 meters is enough to change the stall, so it's okay to try it."

"You can try it, pay attention to maintaining the posture of the fuselage and not enter the stall tail spin." Chief Secretary Wang nodded and issued instructions.

The stall tail spin is not the content of the test flight, and there is no need to test the stall tail spin for the J-10c again, so Chief Secretary Wang specifically reminded him that he does not want to increase the danger only.

"I understand." After Yang Luo responded, he silently counted seconds while stabilizing his fuselage posture.

Today's twenty seconds passed quickly, and we didn't live like the last moment of flying low-altitude and high-speed.

When Yang Luo counted to 20, the angle of attack limit was lifted. Regardless of the system's warning, the positions of canards, flaps, etc. were adjusted again, causing the angle of attack to increase a little more, less than 0.1 degrees.

Although the al-31fn engine was roaring and burst out with the maximum thrust, the resistance also increased with the increase of the angle of attack, and the speed of the J-10c decreased again.

At the same time, the yellow alarm in the cockpit turned into a red alarm, and it sounded rapidly at the highest frequency of "Didi".

Fighter plane stalls!

Sure enough, 26 degrees is the maximum angle of attack for the J-10c during normal flight. The lift that exceeds 26 degrees will become smaller, which cannot offset the gravity and the fighter can stall and fall.

At this time, the J-10c was not falling straight, but was falling on a parabola, after all, there was still a horizontal speed.

Yang Luo has a good grasp of the attitude of the plane. The wings on both sides are stalling at the same time, so they do not enter the tail spin, but are just simply stalling.

Yang Luo was not panicked, and his face disappeared from the solemnity and solemnity he had when he first tested the flight. Instead, he became very calm, and there was even a smile on his lips.

It's just a stall. What's the point of fear? Even the stall tail spin in the death penalty area known as the aviation field, Yang Luo can face it calmly.

"Report the tower, Raptors 11 has stalled." Yang Luo reported calmly.

"Change and return." Chief Commander Wang has seen the flight trajectory of the J-10c from the surveillance. It seems that 145 kilometers per hour is the limit of the J-10c and cannot be lowered anymore. He had to say helplessly, his tone was not anxious because of Yang Luo's stall, but was very calm, as if Yang Luo was not facing danger now and was just flying normally.

Including the others on the tower, there was no look of worry for Yang Luo on their faces, but looked at the screen calmly. After the baptism of low-altitude and large speed watches a few days ago, they had clearly realized Yang Luo's flight skills. And they had just flew out of the limit speed of 145 kilometers per hour. If he couldn't even change the stall now, it would be a big joke.

"I understand, it's changing." Yang Luo replied in a hurry.

When Yang Luo reported that the fighter jet had fallen by more than 200 meters, the drop speed at this time had reached 50 meters per second, and the drop speed was still increasing under the influence of gravity.

The speed is 80 km/h and is still decreasing.

A faint smile appeared on Yang Luo's face, and he adjusted the position of canards, flaps, etc., so that the angle of attack returned to the normal flight range, and the angle of attack limit that had been lifted returned to the locked state.

Pressing rod, dive growth rate.

The nose of the J-10c responded instantly, sinking rapidly, and the flight attitude of the fighter changed.

When a fighter is stalled, the best way to change it is to dive to increase the speed, obtain enough lift and then pull up and change it.

Of course, fighter jets that do not enter the tail spin, and only stalls can also rely on the thrust of the engine to increase their speed, but it is very difficult to grasp the fuselage posture. Once the wings on both sides obtain different speeds before obtaining enough lift, they will fall into the stall tail spin, increasing danger.

Basically no one would take this approach unless the altitude is not diving enough and he wants to fight to save the fighter, but the plane stalls not diving enough, the tower generally chooses to order the sub-un parachuting and will not take the risk of saving the fighter, which is too dangerous.

The J-10c dived downward, and its speed was getting faster and faster. It had already obtained enough speed and the aerodynamic effect had long been restored. However, Yang Luo did not rush to change it, but continued to dive. He held it in for two days and did not fly back so quickly.

"Raptors 11, what are you doing? Hurry up and return." Chief Secretary Wang saw through the surveillance camera that Yang Luo had not been pulling up for a long time, and he reminded him.

"The tower, it's less than twenty minutes after it was launched, just let me fly for a while." Yang Luo said, still not changing it.

Yang Luo's words surprised everyone on the tower and even bargained with the tower.

Chief Commander Wang remembered the news he had heard from the 122nd Regiment, saying that Yang Luo would not return until he was trained, unless he ordered the police, so he had to laugh and cry and ordered: "Raptors 11, today's test flight mission has ended, I order you to return."

The tower had an order and had to comply with it, so Yang Luo had to reply: "The Raptors 11 have been received and are being relocated and are preparing to return."

Just as Yang Luola's rod changed from a dive state, his eyes left from the dashboard that he was staring at, accidentally swept across the desert below the front right, and suddenly he found an abnormal situation.

A ray of light reflected into Yang Luo's eyes. When he looked closely, it was a drone flying in the air. Because it was too far apart, he could not see the specific appearance clearly. He could only recognize it from the outline.

As the test flight airspace of the test flight institute, the airspace above this desert is a no-fly area, and any civilian aircraft are prohibited from entering, and military aircraft also need to be reported.

But now this drone appears here. Whether it is entering by accident, being uneasy, or having reported it, it is worth paying attention and must be checked clearly.

"Call the tower, Raptors 11 found a drone appearing in the no-fly zone. Please confirm whether to report it." Yang Luo reported to the tower, staring at the drone with his eyes tightly, and at the same time he turned the rudder and went over.
Chapter completed!
