As long as the thrust is large, the bricks can also fly into the sky. How fast is the fastest fighter in the world?

Z0z Bart Osborne, who once served as the ATF project manager of Lockheed Martin in the United States, said such a well-known saying, "As long as the thrust is large, the brick can fly to the sky." As long as the slab is equipped with a powerful engine, it can still achieve supersonic speed. Although this is a joke, it can be seen that the engine has a decisive influence on the flight speed of the fighter. Equipped with a good-performance engine, the fighter aircraft can also have good air flight capabilities even in the conventional layout.

Currently, there are mainly four top aero engine manufacturers in the world, General Dynamics and Pratt & Whitney in the United States, Rolls-Royce in the United Kingdom, and United Engine Manufacturing Group in Russia. The F-15, the fastest fighter aircraft currently flying in the United States, is equipped with the F100-PW-229 model manufactured by Pratt & Whitney. This type of engine has a maximum thrust of 13 tons. The two engines give the F-15 excellent flight capabilities, and can fly at a maximum speed of Mach 2.5. In addition to the F-15, the F-22 currently in service in the U.S. military has a good flight speed. It is equipped with a turbofan engine also manufactured by Pratt & Whitney, and can fly at a maximum speed of Mach 2.25.

Russia's achievements in the field of aeroengines are not worse than that of the United States, so it has produced two fighters with exceptional flight capabilities, MiG-25 and MiG-31 interception fighters. The former's power system is the R-15B-300 model developed by the Mikulin/Tumansky Design Bureau, with an afterburner thrust exceeding 10 tons. Although the thrust is not very strong, with the support of the nickel-steel alloy body, the MiG-25 can fly at a maximum speed of Mach 3.2. The latter MiG-31 is equipped with a D-30F6 turbofan engine developed by Perm Design Bureau with a maximum speed of Mach 2.83.

The fastest flight in my country is the J-8 and J-20. The J-8 is known as the "beautiful man in the air". It adopts the aerodynamic layout of delta wings and flat tail and double ventral fins. The power system is two WP-13B turbojet engines. The maximum flight speed on board is 2.2 Mach. But in the J-8 flight test book, there is a record that the J-8 flew at a speed of Mach 2.4, which was the fastest fighter in the field of our military at that time. In addition to the J-8, the J-20 produced by Chengfei came in behind, with a flying speed of Mach 2.6. The J-20 flying so fast is related to its excellent canard wing layout, which can greatly improve the lift and agility of the fighter.

is proud that our country has made certain achievements in the field of aeroengines in recent years, and developed the WS-10B vector engine, which provides a strong "heart" for domestic fighters. With the increasing maturity of domestic engine technology, the speed of my country's fighters will be further improved after installation in the future.
