152 on the simulation machine

The study in the small conference room lasted until five o'clock in the afternoon. The learning content was very large and the density was very high. Even if the six pilots of the Shenlong Squadron had strong acceptance ability, they were a little overwhelmed.

So when Shangqiu announced that today's class would end here, everyone suddenly cheered in their hearts, and they wanted to run away from this place quickly.

Before the class started, Shangqiu was a beautiful girl in everyone's eyes, a Sichuan girl who made people salivate. She was amiable and cute, but after three hours of study, everyone had only one feeling about her, that is, she was afraid.

This beauty has too high IQ and too extensive knowledge. She often asks everyone a question, making everyone dirty. Moreover, she not only has high IQ, but also has terrible emotional intelligence. A few jokes even made Li Donghai not know how to answer.

So such a beauty... let it go!

Can't afford to offend!

Everyone picked up the things and walked outside.

Chen Fei also picked up his laptop and walked out.

"Chen Fei, wait a moment!" Shangqiu, who was rubbing the whiteboard, shouted.

Chen Fei had no choice but to stop.

"Chen Fei, enjoy it slowly, let's escape first!"

Li Donghai and others threw a look and ran away. Soon, there were only Chen Fei and Shangqiu in the small conference room.

"Teacher Business, I'll do it!" Chen Fei stretched out his hand, took the whiteboard wipe and started wiping it.

Shangqiu was not polite either, and packed up his information and laptop.

After Chen Fei wiped the whiteboard clean, turned off the lights in the small conference room, and pulled the tables and chairs neatly. Then the two of them left the small conference room together.

"Chen Fei, how did you deduce the Herbst maneuvering process before?" Shangqiu asked while walking forward.

Chen Fei quickly answered one by one.

Shangqiu listened attentively and nodded from time to time.

After listening, Shangqiu suddenly realized, but she didn't say anything. She just thought for a while, then raised her head and said, "Chen Fei, I'll give you some suggestions."

Chen Fei was stunned and stopped to look at Shangqiu. Shangqiu also looked up at him.

"When you do Herbst maneuver in the future, you must remember the following guidelines: 1. Until the m                                                                                                                                                                                                                                                 �

Chen Fei listened carefully and first kept these three principles in mind one by one. Then he pondered and comprehended them one by one.

He had already obtained the master-level Herbst motor before. After listening to Shangqiu's suggestions and carefully pondering them, he felt enlightened and realized immediately. His understanding of stall maneuver has reached a higher level.

After coming back to his senses, Chen Fei's face was full of excitement. He stood at attention with excitement and saluted: "Thank you, Teacher Shang!"

Shangqiu smiled at her, his face full of brightness.

The two walked forward together again.

"I will suggest Colonel Huang Bin to start your simulator training tomorrow morning."

Um?

Chen Fei was stunned.

Shangqiu smiled and said, "Your theoretical level is enough, you can go directly to the simulator."

"Thank you, Teacher Business!"

Shangqiu's words really worked. The next morning, Huang Bin came to Chen Fei and said, "Chen Fei, you will go with me to do simulator training this morning."

"OK!"

Chen Fei agreed and then went with Huang Bin.

Since the J-10 D is a new aircraft, and as far as Chen Fei knows, there is no large-scale equipment force so far, and there are not even small batches, so Chen Fei and his Shenlong Squadron should be the first batch of formally installed. Therefore, the number of J-10 D simulators is not large, only two.

"The biggest difference between J-10 d and J-10 c is that it has been replaced with a vector engine." Huang Bin first introduced to Chen Fei: "The vector nozzle of our aircraft engine is different from that of the United States and Russia in terms of structure and steering efficiency.

The US f-22 is a binary vector vent, which can only deflect up and down by 20°. The advantages are agile, radar and infrared stealth are better, and the rear body resistance is small; the disadvantage is that it cannot deflect omnidirectionally at 360 degrees, with large weight, large thrust loss, and the loss is about 5%.

In the 1980s, the United States also used f-15 and f-16 as platforms to test a 360-degree axisymmetric vector nozzle, but the omnidirectional vector nozzle was not yet mature during the development stage of the f-22 and could only use binary ones. Therefore, remember, binary ones are not better than omnidirectional ones.

Some people also include vertical take-off and landing f-35b nozzles as vector nozzles, but their nozzles can only be twisted downward by 0-90 degrees. This is not the same as what we said that letting fighter jets make various super-maneuverable vector nozzles.

In fact, it divides the nozzle into three sections, just like dividing a water pipe into three sections, and when the front and rear sections rotate in opposite directions and the middle section, the nozzle will twist between 0-90°.

Although the vector nozzle of the Russian Su-35 is circular in shape, it is actually binary, because it can only be deflected up and down by V, but it can be differentiated. It adds a spherical outer wall deflectable ring before the afterburner chamber and the convergence diffusion nozzle, and the convergence diffusion nozzle is sleeved on this ring.

We are currently the only 360-degree omnidirectional vector thrust in the world that is publicly performed. In other words, we have mastered mature axisymmetric omnidirectional vector thrust technology, including related flight control technology. But you have to understand that the vector engine on our fighter is more advanced than the one that was publicly unveiled. Chen Fei, do you understand what I mean?"

Chen Fei nodded.

This is an old international tradition. The open and exported ones are generally relatively backward. The most advanced ones will always be left to ourselves. For example, the American F22 will never be exported. The ones sold to allies are all F35, so our J-20 cannot be exported, and the only ones exported are J-10 or J-11.

Huang Bin glanced at Chen Fei and smiled and said, "So, driving the J-10 D and driving other types of fighter jets feel completely different. The J-10 D's movements are absolutely clean and neat, and they will never drag on the mud. For example, if you are doing Herbst maneuvering, the J-10 D is very easy, pulling up, rotating, diving, and absolutely efficient and fast."

Chen Fei nodded. Regarding this, he had already reached a rough conclusion on theoretical deduction before.

"One thing you need to pay attention to is that when driving the J-10 D, you must cooperate with helmet sights and combine them to achieve the most perfect effect!"

"Is head aiming easy to use?" Chen Fei asked with some concern.
