Introduction to fifth generation fighter/fifth generation fighter

< , - (, ,) < , Fifth-generation fighter aircraft

The fifth-generation fighter aircraft is a military standard for distinguishing fighter aircraft. There are currently five fifth-generation fighter jets available internationally: the American J-Fighter, the Russian J-Fighter, and the Chinese J-Fighter, as well as the Chinese J-3 that is about to debut at the Zhuhai Air Show.

< ' ' ', Introduction
_ Some people have speculated that the fourth-generation fighter will be the last generation of manned fighter developed in the world. With the development of leading UAV technology in the future , unmanned combat aircraft are likely to replace manned combat aircraft and become the mainstream of future combat aircraft development. In other words, fifth-generation manned combat aircraft will no longer be developed in the future. How credible is this statement? Experts believe that overall, the future development of the fifth-generation fighter aircraft will be in three directions, namely, aerospace aircraft and manned aircraft with a higher level of intelligence than the fourth-generation fighter aircraft. Fighter aircraft.
Most experts pointed out that before the year, although unmanned combat aircraft could participate in combat as main battle equipment, they were mainly used to perform a single attack mission against fixed targets and low-speed targets. In air combat, they were mainly used to fight against manned targets. Fighters are used in conjunction with each other and cannot become a substitute for manned fighter jets. Therefore, the future fifth-generation fighter aircraft, which is the main aircraft type of the Air Force, may still be manned, rather than unmanned.
Experts believe that judging from the current situation, the United States is still paying the most attention to future fifth-generation fighters. First of all, this is because the United States currently has higher reserves and levels than other countries in the fields of aviation technology and military information technology. Secondly, the fourth-generation fighter jets of the United States were deployed at the beginning of this century and were deployed in 2009. Judging from the life span of the equipment fleet, the United States was the first to see the need for replacement of fourth-generation fighter jets. Third, and most important. The United States has always insisted on maintaining an internationally dominant position in military technology, and strives to maintain an epochal gap with other countries in terms of military equipment. It can be predicted from this that the time when the fifth-generation fighter will appear in the future mainly depends on the U.S. research and development schedule.


_ Nowadays, the generations of fighter aircraft are divided according to their functions. There are also two standards: one is the standard of the West led by the United States (now in the fourth generation), There is also a Russian standard (the fifth generation has appeared. It has been distinguished since the emergence of jet aircraft. Therefore, the fifth generation generally refers to the Russian standard, which is equivalent to the United States' third generation. Fourth generation.
We generally use the American standards: (the following are also distinguished according to the standards of Western countries)
Typical first generation: United States: -, -, -, Soviet Union: MiG-(Soviet Union The second generation)
Typical second generation: United States: -,- Soviet Union: MiG - my country: Annihilation
Typical third generation: United States: -, -, -, - Russia: Su-series, MiG-, my country: J-J
The fourth generation (including test aircraft): United States: -, my country: J-(has now made its first flight) J-(since the first flight of J--, this aircraft is not Yes, this aircraft is just a cover.) J-3 (has made its first flight) Russia: - (has made its first flight) Su - (Russia's fifth-generation technical test aircraft, it has been confirmed that it will not be put into service) MiG.( It is also the fifth generation of Russia, but like the Su-F, it will not be put into service)
There are many improvements to the third generation fighter aircraft, calling it the third and a half generation (it has some characteristics of the four-belt fighter aircraft) , such as stealth, etc.), are actually divided into the third generation (Europe's Hurricane, France's Rafale, Sweden's Gripen, my country's JJ)

< ' ' , the first-generation fighter
3_ refers to the first batch of fighter aircraft using jet engines, which appeared about 3 years ago. Due to the use of new jet engines, its combat capabilities have been significantly improved compared to aircraft using turboprop engines. Chapter 1 The appearance of the first-generation fighter aircraft is somewhat similar to that of turboprop-driven fighters, such as the use of straight wings, cannons, and radars that are only equipped on special night fighters. Although they have many advantages over previous aircraft, The first-generation fighter aircraft had great shortcomings, such as its short service life, poor engine reliability, bulky size, and its power could only be adjusted slowly. Typical models of the first-generation fighter aircraft include the German and British Meteor in the late World War II , and later the Soviet Union's MiG-, MiG-, the United States's- and -, etc.

< ' ', second-generation fighter aircraft
3_ mainly refers to the century Typical models of fighter jets developed from the 1990s to the 1990s are the American Super Saber. Due to the adoption of many new technologies, the combat capability of fighter jets at this time has been greatly improved. The aircraft began to use guided missiles such as Sidewinder and Sparrow for visual range For external attacks, radar is also used as a standard configuration to determine the enemy's attack target. New aircraft designs are also emerging in an endless stream, such as swept wings, delta wings, variable swept wings, and fuselages designed according to area law. The use of swept wings The speed of production fighter aircraft finally broke through the sound barrier. An important feature of this period was the emergence of combat bombers (such as - and Su -) and interceptor aircraft (British Lightning and -). The development of interceptors mainly relies on the concept that guided missiles can completely replace cannons and air combat will be conducted within visual range. Therefore, interceptors have a large bomb load and powerful radar, which sacrifices agility such as speed and altitude. . The second-generation fighter aircraft include the Soviet MiG-, MiG-, Su-, British Lightning, American -, -, -, -, -, -, etc.

< ' ', third-generation fighter jets
3_ The third-generation fighter jet mainly refers to the fighter jets that appeared in 2008. During this period, aviation technology developed increasingly maturely, and the development of fighter combat capabilities was mainly achieved through the introduction of missiles and radars with very good performance. Based on the actual combat experience of a large number of guided missiles, planners have redefined the position of close combat in air combat, cannons have once again become standard equipment, and mobility has once again become a priority planning factor. While the development of aviation technology has significantly improved the capabilities of fighter aircraft, its research and development and application costs have also increased significantly. The military has recently had various specialized fighter aircraft, such as night fighters, heavy fighters and attack fighters. Faced with the skyrocketing cost of fighter aircraft, the military has begun to merge the tasks of fighter aircraft. The U.S.-Fighter was originally designed as an interceptor aircraft for the U.S. Navy and is widely used by the U.S. Air Force, Navy, Marine Corps and the armed forces of other countries. This aircraft is currently the only combat aircraft used by the entire U.S. military. Other third-generation fighters include the former Soviet Union's MiG, MiG-, Su-, Su-, France's Mirage, British Harrier, and the United States' - and - etc.

< ' ', fourth-generation fighter
3_ In response to the continued increase in fighter costs and the unprecedented success of -, multi-purpose combat aircraft were launched in the 1990s and early 2000s. Fighters became very popular, and the fighters developed at this time were called fourth-generation fighters. Today's fighter aircraft have multi-purpose capabilities, even if they are designed specifically for a certain mission. Aircraft such as the MiG and Storm have developed special-purpose aircraft for various purposes, and real multi-purpose fighters have also appeared one after another, such as the American Hornet and the French Mirage. Different from the previous generation of interceptors, the design of the fourth generation fighter aircraft focuses on beyond visual range combat and close combat. Fly-by-wire control and relaxed static stability designs are widely used. Typical models of the fourth generation fighter aircraft include the former Soviet Union's MiG-, MiG-, Su--, the French Mirage, the British Storm, the American -, -, - and / -, my country's J-F and J-F, etc.
With the rapid development of aviation technology, a type of fourth and a half generation fighters can also be distinguished. The fourth and a half generations of fighters are mainly the latest fighters in active service. They are characterized by no new developments in aerodynamic technology. Instead, with the rapid development of microchips and semiconductor technology in the 1990s and 2000s, the avionics have made many improvements and adopted Limited stealth configuration. Typical models include the American Super Hornet. It is an upgraded version of /-. Although the basic aerodynamic characteristics remain unchanged, the former uses a large number of leading avionics system technologies, solid-state active phased array radar, and also uses new engines. The aircraft structure is made of composite materials. The weight was reduced and the aircraft's shape was slightly modified to minimize its radar signature. Other fighters that can be classified as fourth and a half generations include my country's J-F and J-B, the Hurricane jointly developed by four European countries, Sweden's, Russia's MiG and Su, and the United States' - and - later batches of aircraft. .

What can now be called the fifth-generation fighter aircraft - and

< ' ' , the fifth-generation fighter aircraft
3_ The fifth-generation fighter aircraft The aircraft is the most advanced generation of fighter aircraft currently developed. The aircraft adopts a stealth design with built-in weapons, and also has a comprehensive avionics system that can reduce the pilot's workload and improve his situation awareness. The characteristics of the fifth-generation fighter aircraft include supersonic cruise, low observability, and simple operation and maintenance.
The use of Admiral jet fighters as a proxy for dividends is a distinction between the aviation and military personnel in the United States and Russia. There is no official distinction defined by national authorities. As for which generation a certain aircraft belongs to, it also depends on the configuration level of its specific airborne system and cannot be lumped together.
