The strongest pilot ever

Chapter 151 Teacher Shang, Am I Right?

151 Business teacher, am I right?

The more Chen Fei listened, the more excited he became. The more he listened, the more he felt like being scratched by a cat's paw.

Shangqiu looked at Fade Chen from time to time. Seeing that he was a little restless at the moment, he asked with concern: "Comrade Fade Chen, is there something wrong with you?"

Fade Chen was puzzled.

There is nothing wrong with him.

He is very good!

How could Shangqiu say that he was not feeling well?
Oh yes!

He quickly remembered that he had been misunderstood by wriggling in his seat like a thorn in his buttocks.

He quickly stood up and said, "Mr. Shang, I'm not feeling sick."

Shang Qiu nodded. She didn't want to let Fade Chen go, and asked, "Then, Comrade Fade Chen, what do you think of the topic I just mentioned?"

Fade Chen actually had nothing to say, but since the other party had spoken, it seemed unreasonable not to say a little bit.

Fade Chen has always been a good student. A good student means that when the teacher asks questions, he must cooperate in time and not let the teacher stand in the cold. So when he was in high school, the subject teacher liked to ask questions about Fade Chen in open classes, because he could always answer questions. With a perfect match, the teacher will answer what kind of answer the teacher needs. Sometimes the wrong answer is deliberately given to the teacher to give the teacher a chance to play. Therefore, at that time, many teachers liked to go to their class for public lectures, so now Fade Chen thought for a while, and said, "Report, Mr. Shang, I don't understand one thing about the question you just mentioned."

"Say it!" Shang Qiu looked at Fade Chen without blinking.

Fade Chen originally wanted to look at Shangqiu, because this is the habit of a good student, but Shangqiu's gaze was too hot, and he couldn't bear it, so he hurriedly lowered his head and said: "You also said just now, J-[-] D’s post-stall performance has been greatly improved compared to J-[-]C, but how much has been improved and how much is it, is there any data to express it?”

Shangqiu was taken aback, she blinked her eyes, and then said: "Do you want to understand the typical stall maneuver mathematical model of J-[-]D?"

Fade Chen was taken aback for a moment, then nodded.

After hearing this, Shangqiu smiled brightly. She pulled the whiteboard over with a swipe, picked up a whiteboard marker, turned around and wrote while saying: "Although the current research has proposed a variety of post-stall maneuvers, I think that through the analysis These typical maneuvers can be summed up as a combination of three basic maneuvers after a stall maneuver, straight flight movement, rapid pitching movement, and rotational movement around the velocity vector, for my classification, Comrade Chen Fei, do you agree?"

Fade Chen nodded.

As expected of Shangqiu's doctoral background, a simple classification divides the post-stall maneuvers that they have been arguing for a long time into three concise types, and this level has to be accepted.

Seeing that Fade Chen nodded, Shangqiu continued: "The other two movements are relatively simple, so let's study the rotational movement around the velocity vector. We decompose the total rotation vector of the aircraft into a component along the velocity vector and three components along the velocity vector. The component of the axis, the total rotation vector can be determined by the total angular rate of the body axis, and the component along the velocity vector is the projection of the total angular rate Ψ on the velocity axis, which is called the steady-state rate. The components along the body axis are three body The component of ωss on each axis is subtracted from the axis angular rate, which is called the oscillation component”

As she spoke, she wrote various mathematical expressions on the whiteboard.

In the small conference room, except for Fade Chen and Yang Dong, the other pilots were all in a cloud of confusion. Sometimes they were confused, half understanding, and sometimes they fell into the clouds, at a loss as to where they were.

Although everyone is talented, what Shangqiu said is too professional after all, at the doctoral level, and after everyone leaves the army, they learn less and less theory, and basically focus on tactics and tactics On, so it is very hard to listen at the moment.

But Chen Fei understood.

He has never given up on theoretical exploration and learning, and he can pick up attributes from time to time. In addition, his IQ has also been improved unconsciously, so he basically understands what Shangqiu said at this moment. up.

Shangqiu swished out the last conclusion in a mathematical formula. After that, she slapped the whiteboard marker on the table, then raised her head and looked at Fade Chen: "Now, you know that J-[-]D is passing the stall. Is there an advantage in maneuvering?"

Fade Chen didn't answer, he frowned and fell into a state of deep thinking.

Shangqiu didn't urge her, nor did she feel dissatisfied because Fade Chen didn't answer in time, she just looked at Fade Chen quietly.

That face is really pretty!

She said silently in her heart.

Just when she was a little crazy watching, and the five pilots below were all wailing in their hearts, saying that I am so handsome, why don't you take a look at me? Isn't Fade Chen just a little bit more handsome than me, Fade Chen suddenly said excitedly : "Mr. Shang, I understand!"

Shang Qiu, who was stunned, was taken aback, and his little leather boots almost tilted. Fortunately, she put her hands on the table in time, so that an embarrassing situation was avoided.

I was really too involved just now, I'm afraid my mouth is watering!

Shangqiu was a little embarrassed, and quickly raised his hand to cover it up.

"Comrade Chen Fei, what do you understand?" Shangqiu quickly changed the subject and asked.

Fade Chen deliberated for another two seconds before saying: "If you follow your derivation just now, then if I fly the J-425D to perform a Herbst maneuver, the process should be like this. My plane starts to accelerate at around [-]km/h. Force, enter the maneuver.

Then increase the angle of attack and decelerate rapidly.

When the lever makes the aircraft rise to a nearly vertical upward state, the angle of attack is 70°, and the speed is about 280km/h. At this time, I push the left rudder and use the thrust vector to roll around the speed vector axis at a large attack angle at a very low airspeed. Turn to make the aircraft deflect 180° to the left, and the maximum deflection rate is about 20°/s.

Finally, the nose is vertically down, and then the stick is slightly released to reduce the angle of attack, and gradually recover from the dive.The turning radius decreased from 823m to 145m, and the whole process lasted only 20s, including the time required to level the aircraft from the nose-down attitude speed of 220km/h.

Mr. Business, am I right? "

"."

Shangqiu didn't answer, she was dumbfounded.

She would never have imagined that Fade Chen could deduce the physical process of Herbster's maneuver from what she said.

The J-[-]D can naturally do Herbster maneuvers, but the maneuvering process in the flight manual is explored by the test pilots again and again with extremely high-risk test flights, but Chen Fei directly deduces it theoretically, and the obtained data is consistent with The real data of J-[-]D is not very different!

This guy
Is it still human?

The Shangqiu vertical and horizontal academic circle has never seen such a perverted freak in so many years!
She was stunned and didn't know how to answer.

In the small meeting, Li Donghai, Yang Dong, Li Cheng, Huang Haijun, and Qin Qingyu also stared at Fade Chen blankly.

What's wrong with this guy today? Could it be that he has fallen under the skirt of this beautiful doctor? With such a fight, he even deduced the process of Herbst's maneuvering. I haven't seen him fight like this before!
and many more!

Why is something wrong!

The Herbst maneuver process he deduced can't be true, can it?

Is he not joking?
Everyone looked at Fade Chen like an alien.
