Chapter 250 How come Jiang Chen knows everything?
"Instructor."

At this moment.

A boy sitting in the back row stood up.

Looking at Sun Zhigao, he asked, "When I was looking up information online before, I saw some netizens saying that the J-10 is a third-generation aircraft, but some netizens said that the J-10 is a fourth-generation aircraft."

"It seems that our country does not have a unified standard, so is the J-10 a third-generation aircraft or a fourth-generation aircraft?"

Sun Zhigao pursed his lips at Jiang Chen and said, "Traitor, I'll leave this question to you."

Jiang Chen rolled his eyes.

Not finished?
Can this matter not be turned over?
He said angrily, "I don't know. Love has several generations. The third and fourth generations just have different standards. Aren't the third and fourth generations the same? As long as it's not level three, it's fine."

Before he finished speaking, Sun Zhigao threw the mineral water bottle in his hand at him, "You filthy boy, you said foul language, do you want to be put in solitary confinement again? If I ask you to answer, then answer me properly. If you explain this matter clearly, I will no longer call you a traitor, and we will put the matter of you skipping a grade behind us."

Jiang Chen then smiled and said, "That's more like it."

Done.

He looked around first.

Then he added, "There are two main standards for classifying fighter jets in the world. One is the Russian standard, also known as the Soviet standard; the other is the American standard."

"There is nothing we can do about it. After all, before 2010, these two countries were not only the main developers of fighter jets, but also the largest exporters."

"Since the whole world is using fighter jets developed and produced by these two countries, it is natural to use their standards."

"Of course, countries like France, Israel, and Sweden can also develop fighter jets. Why don't they have their own standards? Because these countries are almost all vassals of the United States, so they naturally use American standards."

“Back to the topic!”

"The standard for fighter aircraft updates and iterations began after the end of World War II, when jet fighters began to enter service."

"From the first jet fighter in 1944 to today, jet fighters have gone through five generations."

"Some people may question that according to US standards, fighter jets have only been updated four generations."

"I'm behind the times, my friends. Now the Americans have also identified the F-22 as a fifth-generation stealth fighter. As for the reason, I'll tell you later."

Jiang Chen paused.

It continued, "The first generation of fighters refers to the first fighters that used jet engines, which appeared from about 1944 to 1953."

"The use of new jet engines has significantly improved its combat capability compared to aircraft using turboprop engines."

"The first-generation aircraft has some similarities to turboprop-driven fighter jets, such as straight wings and machine guns."

"Oh, by the way, the first generation of fighters also had onboard radars, but they were only equipped on special night fighters."

"Although the first generation aircraft has many advantages over previous aircraft, it still has major flaws, such as its short service life, poor engine reliability, bulky size, and its power can only be adjusted slowly."

"Typical first-generation aircraft include Germany's Me series at the end of World War II, Britain's Meteor, the Soviet Union's MiG-15 and MiG-17 in the 80s, the United States' P-86 and F-, etc."

"Because the advantages and disadvantages of the first generation of fighters were very obvious, the second generation of fighters had already been put into service in the air forces of various countries in the mid-to-late 1950s."

"The characteristics of the second-generation fighter jets can be summed up in four words: high altitude and high speed!"

"So second-generation aircraft are generally supersonic, and their maximum ceiling can even exceed 20000 meters."

"In order to achieve supersonic speed, the second-generation aircraft generally adopts a swept-wing aerodynamic layout design."

"At the same time, the second-generation aircraft has branched out into fighter-bombers (F-105 and Su-7) and interceptors (MiG-21)."

"Fighter-bombers emphasize ground and sea attack capabilities, while interceptors emphasize air combat capabilities."

"Besides, since the second-generation aircraft is equipped with fire control radar and air-to-air missiles, it basically has the capability of beyond-visual-range combat."

"The second-generation aircraft mainly include MiG-21, F-8, F-104, etc. Oh, by the way, the J-5 of our Air Force is considered a first-generation aircraft, the J-6 and J-7 are considered second-generation aircraft, and the J-8 can barely be considered a 2.5 or third-generation aircraft (Russian standards)"

“There is no dispute between the United States and Russia regarding the first and second generation aircraft, but the third generation is different.”

"The former Soviet Union believed that the use of variable-sweep wings on fighter jets was a technological advancement, and that it could basically be classified as a first-generation fighter jet, so the former Soviet Union's MiG-23 was a third-generation aircraft. However, the United States disagrees with this view, because variable-sweep wing aircraft did not bring about a great improvement in aircraft, and at most could be considered half a generation, or 2.5 generations."

"So the MiG-23, Su-15, France's Mirage 3, Britain's Harrier, and the United States' F-4 and F-111 are all third-generation aircraft according to Russian standards, and 2.5 according to American standards."

"Before the 1970s and 1980s, my country used the Russian standard, but after the 1970s and 1980s, it used the American standard, so I will also use the American standard in the future."

"From the 1970s to the early 1990s, multi-role fighters became very popular, so the third-generation fighters were born."

"The characteristics of the third-generation aircraft can be summed up in one word: 'multi-purpose'. What does that mean? It means it has all kinds of capabilities."

"Unlike the previous generation of interceptors, the third-generation aircraft is designed to focus on both beyond-visual-range combat and close-range combat. Fly-by-wire control and relaxed static stability design are widely adopted."

“And the ground/sea capabilities have been greatly improved.”

"There are so many star models of the third-generation aircraft, and I guess most of you here can name them all."

"For example, the famous Su-27 Flanker, MiG-29, France's Mirage 2000, the American F-14 Tomcat, F-16, F-15, F/A-18, etc."

"my country's J-10, J-11 and J-15 are all third-generation aircraft." "For the next fourth-generation aircraft, or fourth-generation and a half fighter jets, the Russian and American standards are different. The American standard is a fourth-generation aircraft, while the Russian standard is a fourth-generation and a half fighter jet."

"I still use the American standard, the fourth-generation aircraft."

"The fourth-generation aircraft is the main aircraft currently in service in the world's air forces."

"The fourth-generation aircraft is characterized by no new progress in aerodynamic technology, but due to the rapid development of chip and semiconductor technology, avionics and other flight electronic systems have made epoch-making progress, and a limited stealth configuration has also been adopted."

"Many improved versions of third-generation aircraft are fourth-generation fighters. For example, the J-10C is an improved version of the J-10. Although the basic aerodynamic characteristics remain unchanged, the former adopts a large number of advanced avionics system technologies, including a glass cockpit, a solid-state active phased array (AESA) radar, and a new engine. The aircraft structure is made of composite materials to reduce weight, and the aircraft shape has been slightly modified to minimize its radar signature."

"Su-30, Su-35, F-15E, F-16C/D, J-11B, J-16, etc. are all fourth-generation aircraft."

"Oh, that's right. Because the Russians are so confident in the combat capability of the Su-35, they created a new level 4++. So according to the Russians, the Su-35 is actually a 4++ fighter."

"As for the fifth-generation fighter jets, there is not much to say."

"The fifth-generation aircraft is the most advanced generation of fighter jets currently under development. The aircraft adopts a stealth design with built-in weapons, and also has an integrated avionics system that can reduce the pilot's workload and improve his situation awareness."

"The characteristics of the fifth-generation aircraft include supersonic cruise, low detectability, and easy use and maintenance."

"Currently, the world's only fifth-generation aircraft are the US's F-22 Raptor, F-35 Lightning, and my country's J-20."

"As for the Russians' T-50? That was used to defraud Indians of their R&D funding. The Russians' real fifth-generation fighter is the Su-57."

Jiang Chen briefly recounted the development history of jet fighters in one breath.

Although it was simple, it still took him almost ten minutes and nearly two thousand words.

So I can't help feeling a little dry in the mouth.

Seeing this, Fu Shiyu quickly handed him a bottle of mineral water.

Jiang Chen quickly took the mineral water and gulped down a big gulp.

And this time.

Fu Shiyu realized belatedly that she had just drunk this bottle of mineral water.

When she thought about the lipstick still remaining on the mouth of the mineral water bottle, and now Jiang Chen had bitten the bottle mouth and taken a big sip.

this.
Isn't it just an indirect kiss?

Think of this.

Fu Shiyu's face suddenly turned red.

However, everyone's attention was on Jiang Chen, so her abnormality was not noticed by others.

Jiang Chen felt that the taste of this bottle of mineral water had a faint orange flavor.

But he didn't think much about it.

Instead, he continued, "I just left you in suspense. Why did the Americans change the fourth generation to the fifth generation?"

"As early as 2007, at the press conference announcing the service of the US F-22 Raptor, Lockheed Martin and the US military proposed that the F-22 is the fifth-generation fighter jet of the United States."

"However, the US standard still does not separate fighters such as the MiG-23, but instead upgrades the previous third-generation and a half fighters to fourth-generation aircraft."

"For example, the F-16C/D was a 2007-generation aircraft before 3.5, but it became a fourth-generation aircraft after 2007."

"As for the reason, it is that the third-generation and a half fighter jets have made too many breakthroughs and progress in many technical aspects, and the third-generation and a half fighter jets are much stronger than the original third-generation fighter jets. They can be counted as another generation of fighter jets, that is, the fourth-generation fighter jets of the new American standard."

"Actually, this is just an excuse from the Americans."

"The real reason is, to put it bluntly, it's about profit."

"Because according to the old American standards, the Russians call aircraft with similar performance in the international arms market fourth-generation aircraft, while Americans can only call them third-generation."

"Fuck, isn't this a rip-off? A generation behind? How can I sell things to an amateur? No, this has to change, it has to change."

“So the so-called new American standard was born.”

Jiang Chen's words were both humorous and funny.

Immediately, everyone in the car burst into laughter.

Sun Zhigao, who was sitting in the passenger seat, also smiled. This kid!
Simultaneously.

He also sighed slightly in his heart.

Ugh!
This kid really knows everything!
So the dean said that we should not force him to grow too fast, we should suppress him
I don't know whether it is right or wrong!!!

ps: This is a long chapter of nearly 4000 words. The reason why the American and Russian standards are written clearly is for the subsequent plot, not to increase the word count.

In addition: Xiao Jianjun’s new book "Captain of a Great Power, Start by Saving Ghost Flights!" has been released. I beg you all to support Xiao Jianjun’s new book.
