Chapter 250 How come Jiang Chen knows everything?
"Instructor."
At this time.
A boy sitting in the back row stood up.
Looking at Sun Zhigao and asking, "When I was checking information on the Internet, I saw that some netizens said that the J-10 was a third-generation aircraft, but some netizens said that the J-10 was a fourth-generation aircraft."
“Our country doesn’t seem to have a unified standard, so is the J-10 a third-generation aircraft or a fourth-generation aircraft?”
Sun Zhigao nuzzled at Jiang Chen, “Rebellious boy, this question I’ll leave it to you to answer.”
Jiang Chen rolled his eyes.
Are you finished?
This matter can’t be settled?
He said angrily, "I don't know, how many generations do you love? The three and four generations just have different standards. Aren't the three and four generations the same? As long as it's not the third level."
After finishing speaking, The mineral water bottle in Sun Zhigao's hand had already been thrown towards him, "You brat, do you want to be imprisoned again for your dirty words? If I ask you to answer, you can answer me properly. If you explain this matter clearly, I will do it in the future." I don’t want to call you a ‘rebellious boy’, but I’m going to stop talking about you skipping a grade.”
Jiang Chen then smiled and said, “That’s pretty much it.”
After that.
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 called 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 world is using these two The fighter jets developed and produced by the country will naturally use other people's standards. "
"Of course, countries like France, Israel, and Sweden can also develop fighter jets. Why don't they have these countries' standards? The country is almost a vassal of the United States, so it is natural to use American standards.”
“Back to the topic!”
"The updated iteration standards of fighter jets began after the end of World War II and jet fighters entered service."
"From the first jet fighter in 1944 to today, jet fighters have been updated and iterated in total It has been updated for five generations.”
“Some people may question that according to American standards, the fighter jet has only been updated for four generations.” It’s considered a fifth-generation stealth fighter. As for the reason, we’ll talk about it later.”
Jiang Chen paused.
Continued, "The first-generation fighter refers to the first fighter jet to use a jet engine, which appeared from about 1944 to 1953."
"Due to the use of a new jet engine, its combat capabilities Its capabilities are significantly improved compared to aircraft using turboprop engines. "
"The appearance of the first-generation aircraft is somewhat similar to that of a turboprop-driven fighter, such as using straight wings and a cannon."< br>
“Oh, by the way, the first-generation fighter aircraft also had airborne radar, but it was only equipped on special night fighters.”
“Although the first-generation aircraft had many features compared to previous aircraft, It has advantages, but it still has big flaws, such as its short service life, poor engine reliability, bulky size, and its power can only be adjusted slowly.”
"Typical models of first-generation aircraft include the German Me" series at the end of World War II, the British Meteor, the MiG-15 and MiG-17 of the former Soviet Union in the 1950s, the American P-80, F-86, etc. "
"Because the advantages and disadvantages of the first-generation fighter jets are obvious, in the mid-to-late 1950s, the second-generation fighter jets were already in service in the air forces of various countries. "
"The characteristics of the second-generation fighter can be summed up in four words: high altitude and high speed! ”
“So second-generation aircraft are generally supersonic, and the maximum ceiling can even exceed 20,000 meters. ”
“In order to achieve supersonic speed, second-generation aircraft generally adopt a swept-wing aerodynamic layout design. "
"At the same time, the second-generation aircraft have branches, divided into fighter-bombers (F-105 and Su-7) and interceptor aircraft (MiG-21). "
"Fighter bombers emphasize ground and sea attack capabilities, while interceptors emphasize air combat capabilities. "
"And because the second-generation aircraft is equipped with fire control radars and has air-to-air missiles as mounted weapons, it basically has beyond-visual-range combat capabilities. ”
“The second-generation aircraft mainly include MiG-21, F-8, F-104 and so on. 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 standard)"
"First generation There is no dispute between the United States and Russia about the second machine, but the third generation is different. ”
"The former Soviet Union believed that using variable sweep wings on fighter jets was a technological advancement and could basically be classified as a first-generation fighter jet. Therefore, the former Soviet Union's MiG-23 was a third-generation fighter jet. But the United States disagreed with this statement. Because the variable sweep wing aircraft has not made great progress in aircraft, it can be considered half a generation at most, that is, 2.5 generations.”
“So it’s like the MiG-23, Su-15, or the French Mirage. 3. The British Harrier, as well as the American F-4 and F-111, are third-generation aircraft according to the Russian standard, and 2.5 according to the American standard. "
"Because our country used them before the 1970s and 1980s. Russian standard, but after the 1970s and 1980s, the American standard was used, so I will use the American standard next time.”
“From the 1970s to the early 1990s, multi-purpose fighter jets were used. It became very popular, so the third-generation fighter was born. "
"The characteristics of the third-generation fighter can be summed up in one sentence, which means it has all kinds of capabilities."< br>
“Unlike the previous generation of interceptors, the design of the third-generation aircraft places equal emphasis on beyond-visual-range combat and close-range combat. Fly-by-wire control and relaxed static stability designs are widely used.”
“ And the ground/sea capability has been greatly improved."
"There are so many star models of the third generation aircraft, and I think most of the people here can know them all."
" For example, the famous Su-27 Flanker, as well as the MiG-29, the French Mirage 2000, the American F-14 Tomcat, the F-16, the F-15, the F/A-18, etc. ”
< br>"Our country's J-10, J-11, and J-15 are all third-generation aircraft." "The next fourth-generation aircraft, or four and a half generations of fighter jets, the Russian standard and the American standard are different again. The American standard is A fourth-generation aircraft, the Russian standard is a fourth-and-a-half-generation fighter aircraft.”
“I still use American standard, fourth-generation aircraft.”
“Fourth-generation aircraft are currently the main models in active service in the world’s air force.”
“Fourth-generation aircraft The first 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 cross-generational progress, and also adopted a limited stealth configuration.”
“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 uses 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 Lao Maozi was very confident in the combat effectiveness of the Su-35, he created a new level 4++, so according to Lao Maozi, the Su-35 is actually a 4++ fighter. "
“As for the fifth-generation fighter, there is nothing to say.”
“The fifth-generation fighter is the most advanced generation fighter currently developed. The aircraft adopts a stealth design with built-in weapons, and also has a workload, and an integrated avionics system that improves its status awareness. "
"The characteristics of the fifth-generation aircraft include supersonic cruise, low detectability, and easy use and maintenance."
"Currently, the only fifth-generation aircraft in the world are the American F-22 Raptor, F-35 Lightning, and my country's J-20."
"As for Lao Maozi's T-50? That is used to deceive India. Lao Maozi’s real fifth-generation aircraft is the Su-57.”
Jiang Chen briefly explained the development history of jet fighters in one breath.
Although it was simple, it took him almost ten minutes and nearly two thousand words.
So my mouth is inevitably a little dry.
Seeing this, Fu Shiyu quickly handed him a bottle of mineral water.
Jiang Chen quickly took the mineral water and took a long gulp.
At this time.
Fu Shiyu realized belatedly that she had just drank this bottle of mineral water.
When he thought that his lipstick was still on the mouth of the mineral water bottle, Jiang Chen had bitten the mouth of the bottle and took a big sip.
This.
Isn’t this just an indirect kiss?
Think of this.
Fu Shiyu suddenly turned red.
However, everyone’s attention was focused on Jiang Chen, so no one else noticed her strangeness.
Jiang Chen felt that the taste of this bottle of mineral water had a hint of orange.
But he didn’t think much about it.
Instead, he continued, "I just sold it out and asked why the Americans changed the fourth generation to the fifth generation?"
"As early as 2007, the American F-22 Raptor was announced to enter service. At the press conference, Lockheed Martin and the U.S. military proposed that the F-22 is the fifth-generation fighter jet of the United States. "
"However, the American standard still does not separate MiG-23 and other fighters. , but upgrade the previous three-and-a-half-generation fighter aircraft to a fourth-generation aircraft.”
"For example, the F-16c/d type was a 3.5-generation aircraft before 2007, but it became a fourth-generation aircraft after 2007."
"As for the reason, the third-and-a-half-generation fighter jets have many technical advantages. There have been too many breakthroughs and progress, and the third-and-a-half-generation fighter jets are much better than the original third-generation fighter jets. They can be counted as another first-generation fighter jet, that is, the new American-made fourth-generation fighter jet."
"In fact, this is also the United States' It’s just an excuse.”
“To put it bluntly, the real reason is related to interests.”
“Because according to the old American standards, the Russians call the aircraft with similar performance in the international arms market. Generation machine, Americans can only call it the third generation.”
“Hey, isn’t this a scam? It’s one generation behind? How can I sell something to an outsider? If it doesn’t work, it must be changed. It must be changed.”< br>
“So the so-called new American standard was born”
Jiang Chen’s words were witty and funny.
Suddenly everyone in the car burst into laughter.
Sun Zhigao, who was sitting in the passenger seat, also smiled, this kid!
at the same time.
He also sighed slightly in his heart.
Alas!
This guy really knows everything!
So the dean said that he should not be forced to encourage his growth, but should be suppressed
I don’t know if he is right or wrong! ! !

ps: The chapter is close to 4,000 words. The reason why the American and Russian standards must be written clearly is for the sake of the subsequent plot, not for the sake of low word count.
Another: Xiao Bianjun’s new book "Captain of a Great Country, Start by Saving the Ghost Flight!" " has been put on the shelves. I beg you all to support Xiao Jianjun's new book.
