"Yes, yes, hold the position, don't rush to trim." Xia Yu held the telescope in one hand and the communicator in the other, and said to the black-painted plane that was doing a flight maneuver in the sky: "The vector nozzle of the J-31 can ensure that you will not stall lightly when you do this action, okay, you can change it." ”

As Xia Yu's words fell, the J-31 in the sky decisively withdrew from the famous awl and maneuvered over a stall, and after leveling it, it went around half a circle and landed on the aircraft carrier.

Awl maneuver is a famous skill of American overstalling, similar to incomplete vector rolling, that is, the aircraft rolls around the forward speed axis, and this is the most important place for real overstall maneuvering, because the aircraft can also carry out certain control in the process of maneuvering.

Speaking of stall maneuvers, many people will surely think of Pugachev's Cobra maneuvers. This maneuver that can only be quickly pulled to lift the nose when the aircraft is at a speed of 420 km, and then flatten down by using air resistance, in fact, in the eyes of many people, it cannot be regarded as a standard over-stall action, because the aircraft is out of control during the maneuver. It is also for this reason that many people have always believed that the Cobra maneuver cannot be regarded as a real stall maneuver.

But in fact, there are many over-stall maneuvers that are developed on the basis of Cobra maneuvers, such as the super Cobra and Golden Hook maneuvers of su35, and even the famous hammer maneuver of F22, which is actually the overstall action of the nose pointing when the Cobra maneuver achieves the maximum elevation angle.

Compared with conventional maneuvers, overstall maneuvers can multiply the instantaneous angular velocity of the aircraft, and at the same time form a huge speed difference with the enemy, it can also extend the flight and attack envelope, which is a very practical and effective air maneuver.

However, when the aircraft has done a stall maneuver, it will show a state of suspension or stagnation for a short time, and then it will lose a huge amount of energy, and it will be difficult to get rid of it if it is pursued by other enemy planes during multi-plane operations. Moreover, the over-stall maneuver maneuver is not something that can be done by any aircraft, and has a lot to do with the engine thrust, aerodynamic shape, fuselage structure, flight control system and the pilot's personal qualities.

But with an aircraft that can do a stall maneuver, the pilot must learn the stall maneuver that the plane can do, because only in this way can the extreme performance of the aircraft be brought into play, and learn one more air combat skill, maybe one day in the future, this skill can save your life.

As the old saying goes, you don't have to be overwhelmed.

J-31 because of the relationship between binary vector nozzles, can do a lot of stall actions, what mongoose, hammer, awl, vector roll these more famous actions, equipped with a new engine J-31 can basically be completed.

Xia Yu, as a test pilot of the J-31, in order to find out the limit of the J-31, began to try to do all kinds of stall maneuvers long before the finalization, although there were many dangers, but because of this, the air combat capability of the J-31 was basically dug out by him.

It has been two months since he came to this latest nuclear-powered aircraft carrier, Xia Yu's flight technical ability has long impressed the carrier-based aircraft pilots of the aircraft carrier line, and even the pilots of the J-15 will come to listen to Xia Yu's teaching, Xia Yu has no idea of hiding his selfishness, so he has been very careful to teach his experience of piloting the J-31 to the pilots on the aircraft carrier, including a variety of conventional maneuvers and stall maneuvers, as long as the students have questions, he will do his best to answer.

Mu Shaoqing naturally saw this qiē in his eyes, and his heart was beautiful. The J-31 formation on the aircraft carrier formed combat effectiveness much faster than he imagined, and this qiē was inseparable from Xia Yu's efforts, and Mu Shaoqing felt that it was really correct to invite Xia Yu to be this special instructor.

"You have to give the J-31 a little more confidence." In the flight briefing room, Xia Yu stood in front of the pilots, still holding the model in one hand, and said on the information board: "I have been flying the J-31 since it was a technical verification aircraft, so I know much more about the J-31 than you." Huang Bing, when you were making an awl, you only changed it halfway through it, because the stall alarm sounded, right? ”

"Yes." Huang Bing scratched his head and explained: "The stall alarm must have sounded for more than 5 seconds, so I was worried that it would crash, so I changed it." ”

"But in fact, the stall alarm only went off for 3 seconds, and you were so nervous." Xia Yu shook his head and said: "This is also the reason why I asked you to only turn off the angle of attack limiter and not turn off the stall alarm when doing maneuvers, and did a stall action at an altitude of 6,000 meters, just to tell you that even if the stall enters the tailspin, the J-31 can successfully change it within two laps, and the height will not drop much at all, so you don't need to worry about crashing." ”

"Yes, I see, I'll pay attention next time."

Xia Yu nodded and began to explain the other questions. In fact, those who can become pilots of aircraft carriers and carrier-based aircraft are the elite among pilots, and they themselves have rich flying experience, so they do not need to worry too much about the technical and tactical literacy of flying.

What Xia Yu needs to be responsible for is actually to speed up their understanding of the new aircraft, help these pilots master the extreme performance parameters of a new aircraft faster, and let them form combat effectiveness faster. At least in this short period of two months, the flight team of the J-31 has been significantly improved in tactical execution.

"It's the right thing to bring you in as a special instructor! Why don't you just go back to the test flight unit, I'll tell the captain and ask him to send a report that you want to come over, what do you think? Mu Shaoqing said and said, as if the more he talked, the more he tasted, and he became bewitched: "Look, this is our country's first nuclear-powered aircraft carrier, there are not only J-15 and J-16 on the ship, but also the J-31 you are most familiar with, if you come, I will give you a captain's position, with high benefits and good treatment, and the navy girls are all top water spirits, much better than you in the army aviation." ”

Xia Yu was sweating profusely, and to be honest, he really hadn't thought about where he would go in the future. When Mu Shaoqing said this, he unconsciously began to recall that he had been under the name of the test flight unit since he was transferred from the 5th Regiment of the 2nd Air Division to the J-31 test flight group, and even if he was transferred to test fly the Shenlong, he was still subordinate to the Air Force.

Think about it carefully, if the mission on the aircraft carrier's side is over, will you really have to return to the test flight unit? What can I fly when the time comes? An improved version of the J-31? Or is it some other aircraft?
