The kind of fighter jet in the world is the fastest in the world

NASA is secretly working on a super-high-speed aircraft X 43, but what does it really look like? All along, the X 43 has been the beginning of the dragon without seeing the end. Recently, NASA finally unveiled the mystery of the X 43A ultra-high-speed aircraft:

This aircraft does not need rocket power, but the top speed can reach 10 times the speed of sound, making it the fastest aircraft in the world today, flying from the east coast of the United States to the west coast in just half an hour! American scientists call it the most significant breakthrough in aviation technology since the Wright brothers' first flight. However, scientists in other countries believe that the chances of using this aircraft for civilian use are very small, and the real purpose of the United States in developing it is to deter other countries and consolidate its hegemonic position.

Other countries have to be on guard.

This is the x 43a

On April 18, the California desert was very windy, but bad weather did not stop reporters from making their way to Edward Air Force Base, where NASA announced that it would show off its elaborate ultra-high-speed aircraft X 43A model for the first time. According to NASA scientists, the X 43A is the most significant breakthrough in aviation technology since the Wright brothers' first flight.

The model machine was parked on an asphalt runway at the Edwards site. When Joel Sizi, the executive officer of NASA's X 43 program, pulled down the blue cloth on X 43a, the reporters on the scene were all amazed: so beautiful!

This small, delicate plane looks a lot like a surfboard.

Next, Siz gave the reporters a few things about the X 43A. NASA's new X 43A aircraft is powered by a ramjet engine, the fuselage is meters long, the fuselage is black, and the maximum speed will be Mach 7, that is, nearly 8,047 kilometers per hour, which is equivalent to seven times the speed of sound, and it only takes half an hour to fly from the east coast to the west coast of the United States, thus breaking the record for the fastest jet engine without rocket power.

The fastest aircraft can reach speeds of up to 3-4 yards per hour, and the fastest fighter jets will not exceed 2 yards.

It was the MiG-25 and the American SR-71 reconnaissance aircraft.

<> What is the fastest speed of a fighter jet?

The unique attributes of air power are high-speed maneuverability, long-range combat, and fierce assault. Among them, high-speed maneuvering is the most striking feature of fighters. The fastest fighter in the world was the MiG-25 aircraft of the 60s and 70s of the last century, which reached a speed of 2,982 kilometers per hour and a number of meters in the 500-kilometer fighter race in October 1967.

The fastest fighter still in service is the MiG-31, which has 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.

In the late 70s of the last century, the combined effect of several important factors led to a great change in the design ideas of the fighter.

First, reconnaissance satellites have developed rapidly, and the demand for high-altitude and high-speed strategic reconnaissance aircraft has decreased.

Second, the practice of air operations in the Vietnam War proved that air combat mainly took place in the subsonic and transonic ranges, and there were few opportunities for air combat under supersonic conditions.

Third, Colonel Boyd, an expert in air combat tactics, put forward the concept of "energy maneuvering" emphasizing the residual thrust per unit weight, and the OODA air combat model of "observation, judgment, decision-making, and action" that highlights the leading role of information, which has greatly influenced the direction of fighter design, and the new fighter emphasizes maneuverability rather than high-speed flight.

Therefore, the representative models of the third-generation fighters, the F-15, F-16 and Su-27 aircraft, have a maximum level flight m of about Lu Pai, and do not pursue a very large flight speed, and the number of m in medium-range air combat is generally in between, but they all emphasize the installation of advanced pulse Doppler radar (now Ruqi has begun to replace active phased array radar in some models).

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.
