150 Theoretical Study

Since Chen Fei got the flight manual, he has been studying that thing and has hardly gone out until Huang Bin found them again and said that Dr. Shangqiu had arrived. At 2 pm, everyone went to the conference room on time to start theoretical study.

At 130 pm, everyone arrived at the small conference room on time.

Originally, Chen Fei didn't want to come, but when Li Donghai heard that Dr. Shangqiu was a beauty, he became restless early in the morning, so he pulled everyone to the small conference room at half past 10:30 to sit.

Unfortunately, Bai was excited. At two o'clock, Shangqiu was late.

At 2:037, everyone heard footsteps coming from outside the door.

Hearing this voice, even Chen Fei put down his flight manual and turned his eyes to the door. He was actually very curious about Dr. Shangqiu.

Soon, a woman appeared at the door with black-framed glasses, but Chen Fei could see that she was not myopic at all, and there were no lenses in the glasses she wore, and the glasses were completely for decoration.

She was wearing a summer dress.

It was January and February was not yet here, and the weather was still a little cold. Although the weather was a bit abnormal in the past two days and it was much hotter than usual, it was not as cool as it was.

When Li Donghai saw Shangqiu's outfit, his eyes lit up.

Shangqiu walked in quickly with a briefcase.

Walking to the podium, she put her briefcase and looked around.

Her age is not a few years older than Chen Fei and the others, but she is not at all afraid and her aura is even stronger than anyone in the small conference room. When she looks at everyone, she is really like a teacher looking at students, as if the boss of the military region is coming, she can be calm and relaxed.

Her eyes finally froze on Chen Fei.

Chen Fei was originally looking at her, but when he saw her eyes sweeping towards him, he quickly lowered his head and pretended to be flipping through the flight manual.

After waiting for two or three seconds, he felt that it should be almost done, so he raised his head, but found that Shangqiu's eyes were still staring at him brightly, scaring him like a frightened deer, and quickly lowered his head.

What Chen Fei didn't know was that his action made a beautiful smile appear on Shangqiu's face.

cough--

Shangqiu coughed, and then said in a crisp voice: "Hello everyone, my name is Shangqiu. From today to tomorrow, I will be responsible for introducing some relevant situations of J-10 D to you. If you don't understand, you can ask me! Today is our first class, but I was late for the first class, so I will apologize to you first!"

She spoke Sichuan dialect, but did not speak Mandarin, her voice was crisp and crisp. She was also a typical Sichuan girl with fair skin, beautiful and long legs.

After introducing himself concisely, Shangqiu began to introduce the relevant content of J-10 D. Her explanation was very well-organized. She started with J-10 A, first talking about why there was J-10 A, and then talked about the difficulties Cheng Fei encountered when designing and developing J-10 A, and how he overcame it. Then he talked about the development of J-10 B and J-10 C. Finally, the J-10 D was introduced naturally.

Why did we need to develop the J-10 D? What problems were encountered in the process of developing this fighter, what were the controversies, and how to overcome them in the end? What are the advantages and disadvantages of this fighter, what kind of battlefield is it suitable for, etc., she explained them one by one.

Although her explanation is not like some big names, she makes everyone laugh, after all, what she says is professional content and cannot be like crosstalk. However, what she says is still very good. After listening to his explanation, Chen Fei or anyone else has a very thorough understanding of the development history of our army's fighter jets. But most importantly, her understanding of air combat has reached a higher level, because a thorough understanding of the advantages and disadvantages of each type of fighter jet is actually a process of in-depth understanding of air combat.

"The biggest breakthrough of J-10 D is that it has been replaced with a brand new vector engine. With this aircraft engine, J-10 D can easily achieve super maneuverability.

Okay, let’s first talk about hypermotorism. I think what we call hypermotor can actually be divided into large concepts and small concepts, or broad concepts and narrow concepts.

Supermaneuver can be divided into two categories: superconventional maneuver and supersonic maneuver.

We are not saying that traditional third-generation aircraft cannot fly maneuverably at supersonic speeds, but third-generation aircraft can only fly supersonic for a short period of time. Once it maneuveres violently, its flight speed will quickly drop to subsonic speeds; on the other hand, even if it is maneuverably at supersonic speeds, the overload will not exceed 2g.

Since the third-generation aircraft does not have supersonic maneuver, it creates an illusion that supermaneuver is equivalent to superconventional maneuver.

Some people will list papers from many years ago and say that the two are the same thing.

This is how it can be understood for third-generation machines, but now it has entered the era of fourth-generation machines. If the two are still equated, it means that the concept of size and size is not distinguished, confusing the broad and narrow hypermotorization."

Shangqiu started talking in a daze.

"So, after the J-10 D is replaced with the SAR, it can immediately enter another stall maneuver after completing an extraordinary maneuver.

For example, at the previous air show, before entering the fallen leaves, the J-10B made a straight backflip with almost no radius.

When the plane flips to a near normal level, if you continue to fly forward instead of falling leaves, it is equivalent to doing big-handedness - on maneuvering.

The J-10B raises the nose high, which can be used for cobra maneuvering or hammer maneuvering. The difference between the two is that when the nose elevation angle reaches the maximum, the nose returns to the forward state, and the cobra maneuvering is completed; if the fuselage is flipped 180 degrees sideways and the nose is instantly changed to downward and dive downward, the hammer maneuvering is completed.

In contrast, hammer maneuver is more practical.

The Su-27 cannot complete the hammer maneuver. It can only wait for the cobra to complete, the nose will return to flying forward, and then control the plane to roll before turning down. In this way, the controllable direction of the nose will change much slower and lose its practical significance.

Therefore, after the J-10 D replaced the New Aircraft Engine with vector thrust, it greatly improved the air combat performance of the fighter."
