September 27
The 14th China Air Show Press Conference
Air Force spokespersonCol.Shen Jinke, the Air Force, said
"China's fifth-generation fighter J-20
has been spread throughout the 'southeast, northwest, north and center'"
This is the first time that an Air Force spokesperson used
"fifth generation fighter" to express the J-20
has attracted widespread attention
fighter generation mainly has several types of
fighter 0 fighter 0 is a classification of one or several aircraft families with similar performance, similar technologies and similar tactics. When the performance and technology of the new model are comprehensive and significant, it will be called the "new generation".
Regarding the generation of fighter jets, there are several methods such as "traditional four-generation division", "Russia five-generation division", and "American five-generation division".
"Traditional Four Generation Division" only covers supersonic fighters, listing double-sonic fighters that were put into service in the early 1950s as the first generation, double-sonic fighters that were put into service later as the second generation, fighters that started in service in the mid-1970s and have high maneuverability as the main feature, and fighters with higher comprehensive performance that began to serve in the 21st century as the fourth generation.
"Russia's Five Generation Division" is roughly the same, but the second generation of swept-wing aircraft ( MiG-23, F-111) in the "traditional four generation division" is listed as one generation, which is called the third generation; other divisions are the same, so there is one more generation. This division method has been adopted by the Soviet Union and has been used in Russia.
"Fifth Generation Division of the United States" lists jet fighter as the first generation, high subsonic and swept-wing fighters as the second generation, low-sonic fighters and Ma2 first-class fighters are both listed in the third generation, and the fourth and fifth generations are divided mainly based on comprehensive performance improvement.
How to draw the generation of fighter jets in my country
Permanent director of the Chinese Aviation Society and consultant to the Science and Technology Committee of China Aviation Industry Corporation Zhang Juen believes that in order to align with the international level, my country can also agree with the statement that fighter jets have developed to this day. On the basis of integrating the above three generations, jet fighters are the main line, the first three generations are mainly speed and the latter two generations are mainly comprehensive performance to divide the generation. Zhang Juen suggested that it can be called the "New Five Generation Division Method". The typical characteristics and representative models of each generation are summarized as follows:
First-generation fighter : contains early jet type and subsonic and high subsonic fighter jets from the 1930s and 1940s (Ma0.6~0.98). The representative models include MiG-15, F-86 and my country's J-5. second-generation fighter : Ma1 first-class and low-sonic fighter (Ma1.3~1.5) that began to serve in the early 1950s. The representative models include MiG-19, F-100 and my country's J-6. third-generation fighter : Ma2.0 first-class fighter that began to serve in the late 1960s. Representative models include MiG-21, F-4, F-104 and my country's J-7 and J-8. Fourth-generation fighter jets: fighter jets that started service in the mid-1970s, with high maneuverability as the main feature and significantly improved comprehensive performance, representing models include MiG-29, Su-27, F-14, F-15, F-16 and my country's J-10 and J-11. fifth-generation fighter : a new generation of fighter jets that have begun to serve in the 21st century. The representative models include F-22, F-35, Su-57 and my country's J-20.
Zhang Juen also believes that the generation of fighter jets will help reflect the technical and tactical characteristics of aviation equipment, compare and learn from the laws of equipment development, and facilitate the public to understand and recognize the development and progress of fighter jets. However, the generation of fighter jets is just a classification, and does not represent combat capability, nor is it a technical standard. We should always adhere to the guidance of the development of equipment based on demand and measure the equipment level by combat effectiveness standards.
