The speed of the fifth-generation fighter can reflect the aero engine of its own device, comprehensive performance and advanced degree, China, the United States and Russia all have fifth-generation fighters, and the flight speed is slightly different, and it can also be seen that the three countries still have their own gaps in the level of research and development of air fighters.
The American F22 has a speed of Mach 2.25
As the world's first fifth-generation fighter, the emergence of the F22 has led the technical standards of the world's fifth-generation fighters, and also created a template for the presentation of combat power as a reference for the world.
The United States even thought that within a few years, no other country in the world would have the strength to develop a fifth-generation fighter with the same combat power, so it rashly closed the F-22 production line. Although the drawings and some of the remaining materials were sealed, the United States used 10 years to restart the production line of the fifth-generation fighter, but it ultimately failed.
The F22 has a very advanced aero-engine unit, equipped with two F 119 turbofan engines, providing continuous stable and strong power support, which also makes the F22 have a brilliant endurance.
This is also the basic guarantee for the development of the United States' air combat power, and the service life of the aviation engine equipment developed by the United States is still the first in the world, but the aircraft designed by the United States also has a very obvious weakness, that is, the applicability is very poor, and it needs to have the special environment required by the fighter itself, such as F 22 needs to be stored at constant temperature and humidity, and it is necessary to rest and maintain for a long time after each battle.
Even if it has obvious advantages and disadvantages, it does not prevent the F 22 from still being the world's most advanced fifth-generation fighter, and has excellent stealth capabilities, and even creates world-leading related technologies in terms of creating stealth coatings.
The F 22 can achieve 2.25 yards per hour and a flight speed equivalent to about 2,600 kilometers per hour, breaking through the thermal expansion value, as a manned fighter, it is also a precedent for the world's fifth-generation stealth fighter.
Russian Su-57 speed Mach 2
Russia's Su-57 fighter, previously codenamed T50, has also experienced a very stumbling research and development process. Russia's R&D plan for the 5th generation fighter was established more than 30 years ago, but it has been stranded, and it was not until 2021 that the Su-57 was officially put into service.
Russia and the Soviet Union during the military research and development in the same line, are not good at complex electronic equipment, to be able to create a stealth ability of the Su V period, has been beyond the world's expectations, not to mention that this ancient fighter has advanced electronic equipment and radar, has exceeded Russia's previous overall planning for building fighters.
However, the particularly slow construction speed of the Su-57 fighter has revealed Russia's weakness in assembling and debugging complex parts, especially as a fifth-generation fighter, which also requires pilots to make independent judgments and adjustments according to the battlefield situation when flying.
However, Russia's advantages are also very obvious, the fighters built are all cast with high hardness, whether it is extremely cold weather or harsh environment, Russian fighters can stably exert their design combat power, and will not show squeamishness and easy to break down like American weapons.
The speed of the Su-57 reached Mach 2,500 per hour, which is equivalent to flying 2,500 kilometers per hour, in fact, the MiG series built during the Soviet Union in history can reach more than 3,000 kilometers per hour at the fastest, with a simple comparative speed, two AL-41F 1-117S engines are installed, and the power is strong, Russia's fighter is still the world's first existence, but at the same time, coupled with the stealth function, and the fifth generation fighter technology to measure, then Russia is still behind the United States.
In particular, the West does not recognize the 5th generation fighter created by Russia, believing that it is only 4 and a half generations at most, and the stealth effect is also the most backward performance among the 5th generation fighters.
Russia is also worried about the Su-57 building and industry, so it seems that more efforts are needed to improve the overall strength of fifth-generation fighters.
The Chinese J-20 has a speed of Mach 2.45
As a rising star of the 5th generation fighter, the J-20 was developed late, but the progress was very fast, and the entry time was earlier than the Russian Su-57. Nearly 20 with a late-mover advantage performed well in terms of speed, even exceeding the flight speed of the F 22 Raptor, some netizens said that because the United States F 22 public data 2.25 Mach per hour, the mainland in order to keep a low profile, only publicly stated that the J-20 speed is close to Mach 2.2 per hour, in fact, the speed of the J-20 is not less than Mach 2.45 to Mach 2.6.
Western media said that it was unbelievable that the two turbofan 10C engines that should be installed for the J-20 fighter are far inferior to the aero engines of the United States and Russia in terms of overall thrust, but China has made up for the lack of thrust by relying on high-tech means, from the material weight reduction of the fighter, the lightness of the whole aircraft, fuel saving, to the overall streamlined design, which is more conducive to the rapid flight of the fighter. Therefore, it is not an exaggeration that the J-20 reaches Mach 2.45, but it does have this strength.
As an advanced fifth-generation fighter, the J-20 has laid the foundation of the core combat power of the Chinese Air Force since its inception and has made an important contribution to building China's air iron fist.
As an advanced fighter with fast speed and precise control details, the J-20 can achieve surprise attacks and destroy the enemy's air defense network.
