What kind of speed can today s fighter jets reach?

The fastest vehicle at the moment is 15 times the speed of sound of the X-51, and that thing is a human running a rocket, and it can't even turn a corner.

At present, the maximum speed of the fighter is 3 times the speed of sound, and the representative work is the high-speed interceptor series of the former Soviet Union from the MIG25 33, which is characterized by a very huge engine and vent and a rocket-like fuselage, and can reach the speed of Mach 3 for a short time at an altitude of 2W meters, but the maneuverability and stability are basically at the level of human rockets. The maximum speed of modern fighters is generally about 2 times the speed of sound, and the fastest F22A can reach Mach, but because it is very fuel-intensive to open afterburner, generally speaking, fighters maintain cruising speed, try to keep fuel for combat use, and the fastest cruising speed is still F22A, which can reach Mach.

More than 10,000 kilometers per hour! The world's fastest aircraft is now setting a new record.

On November 17, Beijing Evening News reported that NASA successfully conducted a flight test of the unmanned hypersonic test aircraft X-43A on November 16 local time in California (early this morning Beijing time). The X-43A test aircraft flew at a speed of more than 10,000 kilometers per hour, which is twice the speed of sound, thus breaking the record set by an X-43A test aircraft of the same model in March this year, and once again setting a record for the highest flight speed of the aircraft. Yesterday afternoon local time, the X-43A test plane was carried by a modified B-52 aircraft to an altitude of 10,000 meters at Edward Air Force Base in the desert north of Los Angeles, California.

In aerodynamics, such a high-speed flight is called "hypersonic flight". NASA's X-43A program, which aims to build an aircraft that can reach the edge of the Earth's atmosphere, has a planned development period of eight years and a research budget of $100 million.

The rest of the people who have gone through actual combat are the Blackbirds, and the speed of sound has actually been retired. What a rich country! At present, it should be said that the best is the F22, the only cruising supersonic fighter, and the next generation of American fighters is probably a supersonic unmanned fighter.

The MiG-25 can reach Mach 3, which is the fastest aircraft ever installed.

However, the fighters after the third generation mainly pursue maneuverability and agility, and do not pay much attention to speed requirements, which are generally enough to reach Mach 2.

SR-71 is known as Mach 3, I feel that this is, and it is left and right, the MiG-31 is known as Mach, which is still reliable, the fastest in the actual combat test is the MiG-25, and the missiles can't catch up with it, and the American verification machine X-51 is the fastest Mach 6-7, but it doesn't have much practical significance, and it uses a scramjet engine.

Half of the afterburner is at Mach 2 MiG-31 can reach more than three times It's not a technical limitation It's that the pilot can't stand it The current fighter has a gravitational acceleration of 9 10g when it is overplanted and maneuvered, and at this time the pilot has blacked out No matter how big it is, he will be dizzy So it won't be faster This is one of the reasons why Lao Mei is desperately researching unmanned fighters The computer will have problems, but it is less accurate than people Used in fighter jets, of course, it can greatly improve the maneuverability and high speed of the aircraft Fear of death is also the reason I hope it helps

Approximate times the speed of sound. The record set by the American Blackbird reconnaissance plane has never been shot down by a missile, because the missile can't catch up, hehe.

Modern fighters have long ceased to pursue meaningless high speeds. The tattered MiG25 and MiG31 could only reach the maximum speed of Mach in a slow and instantaneous manner by running the afterburner for long periods of time, at the expense of the combat performance of almost all other fighters. The only high speed pursued by modern fighters is supersonic cruise, that is, the ability to fly at supersonic speeds for long periods of time without turning on the afterburner, such as the F22A.

Both the American SR-71 and the Russian MiG-25 can reach Mach. The performance indicators of the MiG-31 can also reach Mach But it has never flown before.

The main focus of modern fighters is on multi-function, especially over-the-horizon attacks and stealth, and speed is meaningless, because the speed that the existing engines can provide is far worse than missiles.

The fastest fighters are the Russian MiG-25, with the MiG-31 at a speed of Mach (935m s), which is mainly used for reconnaissance.

The fastest of the military aircraft is the American SR71 reconnaissance aircraft, more than Mach 3 (1020m s), there is no record of being shot down, but it is said that the detection effect is not good, and it will leak oil when flying.

The F22 is an American fifth-generation fighter, and the fastest speed described in written records as Mach (850 m s) is Mach, but it can never be as high as Mach. The MiG is even slower, Mach only.

The only aircraft with more than Mach 4 is the American X-43A demonstrator, which is up to Mach 10 (3400 m s) and is recognized by the Guinness Book of World Records as the fastest aircraft, but only for experimental purposes.

If the Mach number is to be used as a unit of velocity, it is necessary to give both altitude and atmospheric conditions (generally the default is international standard atmospheric conditions), such as indicating that the flight speed is times the local speed of sound.

For example, stratospheric air is thin and has only horizontal airflow, no weather changes, low air resistance, and high visibility. At sea level at 0, the speed of sound is about; The speed of sound at an altitude of 10000m is about 1062 km h.

Therefore, the MA value cannot be converted into a fixed unit such as km h or MPL (miles per hour, commonly known as "mai"), and the Mach number cannot be used as a unit of speed.

The above content reference: Encyclopedia - Mach.

The speed of fighter jets is basically more than 1,000 kilometers per hour, and the fastest fighter in the world is the MiG-25 aircraft in the 60s and 70s of the last century, and in the 500 km fighter race in October 1967, the speed has reached 2,982 kilometers per hour, and the number of m flies has reached.

The fastest fighter still in service is the MiG-31, which reaches a speed of 2,992 kilometers per hour. Of course, there must be certain conditions for the MiG-25 and MiG-31 aircraft to achieve such a high flight speed, that is, the aircraft has no external plug-in, reduced fuel load, and high-altitude flight.

The one that ranks first among the fastest fighters should actually be considered interceptors, that is, fighters whose main task is to intercept air targets. In the 60s and 70s of the last century, the US Air Force was equipped with high-altitude and high-speed strategic reconnaissance aircraft SR-71, which was difficult for ordinary interceptors to intercept, and its flight altitude also exceeded the high limit of the kill zone of the main combat surface-to-air missiles at that time. For the Soviet Air Force, to deal with the threat posed by the SR-71 reconnaissance aircraft, it was necessary to have more advanced high-altitude and high-speed interceptors, and it was in this kind of operational demand that the MiG-25 and MiG-31 aircraft developed by the Soviet Union.

From the perspective of the outside of the cabin, the pilot could observe that the scene kept changing with the acceleration and rolling of the fighter plane, flying over the snow-capped mountains, crossing the ocean, and the moment the fighter plane passed by at high speed, he even heard a whistling sound in his ears.

The fastest speed reaches more than 1,000 kilometers per hour, like a flash of lightning flashing, and the speed is particularly fast.

The fastest fighters are the Russian MiG-25 with MiG-31. The speed is Mach. 935 meters per second. This one is mainly used for reconnaissance aircraft.

The maximum speed of a fighter is 510 kilometers per hour. This is based on the test data of the China Insurance Research Institute.

Under normal circumstances, it flies about 1,000 kilometers per hour.

Fighter aircraft mainly refer to fighter planes and attack aircraft. It is characterized by excellent flight performance, flexible maneuverability and powerful firepower; Modern advanced fighters are mostly equipped with various search and aiming fire control equipment, and can attack all air targets around the clock.

Peculiarity. Increase the average combat speed of the aircraft, and the aircraft can fly at supersonic speed without afterburner.

Further improve the comprehensive working capacity of various systems and equipment on board, and improve the way of information transmission and display.

Increase the ability to cooperate with unmanned combat aircraft.

It is possible to gradually replace fly-by-wire manipulation, replace electrical information with optical information, and replace cables with optical fibers, which can greatly reduce the danger of being injured by electromagnetic shock waves and improve the anti-interference ability.

Improved aerodynamic performance after stalling, enabling the aircraft to perform certain "overstall maneuvers", improving agility and close-quarters combat capabilities.

Electronic countermeasures capabilities will continue to develop.

Reduce the impact of the application of stealth technology on the type of combat mechanism. In addition, the reliability and maintainability of the fighter will be continuously improved.

The unit of fighter speed is Mach, one Mach is twice the speed of sound, that is, more than 1000 km h (abbreviated as 1000), and the higher the engine power, the faster the aircraft. The Su-27 fighter imported by China is equipped with two high-power engines, and the top speed has not been unified, but it is more credible Mach.

China's fighter is named after J-X, the early J-5 is subsonic, J-6 is transsonic, J-7 is a supersonic fighter, the maximum flight Mach number is, J-8 is a high-altitude high-speed fighter, in order to sacrifice part of the maneuverability to make up for the speed advantage, the maximum flight Mach number is, is currently the fastest fighter in China, J-10 is a multi-purpose supersonic fighter, the maximum flight Mach number does not exceed 2, J-11 is the domestic version of the Su-27, the maximum flight Mach number does not exceed 2.

It's a J-8 fighter.

There is information that it can dive up to Mach, downstairs you are wrong.

How can the J-11 be only Mach 2.

Absolute Mach. Otherwise, there can be no P42 speed record.

3920 kilometers per hour. The fastest fighter SR-71 Blackbird reconnaissance aircraft, a hypersonic reconnaissance aircraft developed and manufactured by Lockheed and NASA in the United States. The SR-71's most powerful thing is its unrivaled speed, the design of the SR-71's air intakes allows it to cruise at speeds beyond Mach, and it is also its effective speed, which is 25,900 meters at an altitude of 3,920 kilometers per hour.

The reason for the speed of the SR-71.

The SR-71 special radar absorbent material gives the reconnaissance aircraft excellent concealment, and the cesium-based fuel additive can reduce the visibility of the waste plume to the radar. Aerodynamically, the Blackbird's spine section creates powerful vortices and generates additional lift, resulting in unexpected aerodynamic performance improvements.
