The maximum speed of the first generation aircraft is m0.9-1.3; Loading artillery, rockets and first-generation air-to-air missiles; The aircraft is also equipped with an optical electromechanical sight and a first-generation radar.

The second-generation aircraft has a maximum speed of M2-2.5 and is equipped with second-generation air-to-air missiles and machine guns. It is also equipped with a second-generation radar and a fire control system with certain interception capability.

Compared with the second generation, the third generation has little maximum speed advantage, but it has added medium-range and close-range fighting missiles and rapid-fire guns; It is also equipped with the third generation radar, omni-directional, all-altitude, all-weather fire control system and avionics system. Mobility has also been greatly improved.

The fourth generation machine has "4S" standard: stealth, super cruise; Combat awareness and effectiveness of super mobility and super avionics.

The fifth generation machine is a stealth drone. Compared with the fourth-generation aircraft, the fifth-generation aircraft has a good balance between stealth and maneuverability at various altitudes and postures through full wing-body fusion and large lift-drag ratio design. If the fourth generation computer is based on information system, then the fifth generation computer is based on the Internet of Things. The real integration of land, sea, air, sky, electricity and network has been realized, and the interconnection based on the Internet of Things has been realized.

Fighter history

After the 1980s, the maximum speed of fighter planes at high altitude was above 2,000 km/h, the allowable maximum speed at ultra-low altitude was 1.350km/h, and the ceiling was about1.8500 m. Most fighters had a maximum range of about 2,000 km without auxiliary fuel tanks, and they had auxiliary fuel tanks of 5,500-6,000 km. The combat radius is over 800 kilometers. It takes about 2 minutes and 30 seconds to accelerate from Mach 0.9 to Mach 2.0.

It takes about 30 seconds to rise from sea level to 1 0000m. The maximum sea level climb rate exceeds 300m/s, and the minimum radius of low-altitude slow hovering is about 450m. The allowable overload of aircraft is 9.0g, and the instantaneous hovering angular velocity of some fighters is 30 degrees per second.

The nose can be deflected by a large angle in a short time, which is conducive to launching combat missiles. This new fighter is easy to maintain, and some fuselage skins can be opened 60% for quick maintenance or replacement of its components. Replacing an engine can be completed by three people 1 hour.
