What is the fastest airplane speed in the world?

More than 10,000 kilometers per hour! The world's fastest aircraft set a new record today 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 the 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 fastest aircraft developed by the United States can reach 10 times the speed of sound Beijing time on October 28 According to foreign reports, the US Department of Defense is currently stepping up the development of a hypersonic vehicle and plans to test it in 2008. Lockheed Martin was responsible for the development of this supersonic unmanned aircraft, known as the Falcon. The program was supported by NASA and the U.S. Department of Defense's Defense Advanced Technology Research Agency.

It is reported that the company Lo Ma will first build two prototypes of the Falcon. The latest Falcon hypersonic UAV will replace the SR-71 Blackbird high-altitude high-speed reconnaissance aircraft in service with the US Air Force. So far, the program has received a total of $100 million in grants.

According to a spokesman for Lo Ma, the new aircraft will reach incredible speeds in stages: it will first accelerate to twice the speed of sound with the help of a turbojet engine, after which the equipped ramjet engine will start and accelerate the aircraft to four times the speed of sound. The maximum flight speed of the "Falcon" will reach 9 10 times the speed of sound and it will be the fastest flying aircraft ever made.

For the Falcon UAV, in addition to the new engine, the high-temperature resistant materials used to make the body are also indispensable. Experts are now discussing two design options: one is the use of metal alloys; The second is the use of new ceramics.

In the future, it is also possible that the new technologies developed during the development of the Falcon will be used to build a new generation of long-range attack aircraft, bombers and fighters. In addition, the Defense Advanced Technology Research Agency of the US Department of Defense wants to use the Falcon UAV to launch microsatellites. Experts noted that the use of such an aircraft could reduce the cost of launching small payloads into orbit to $5 million.

The fastest in the world at the moment is NASA's test machine X 43, which uses a supersonic ramjet engine at a speed of Mach 10.

The fastest scrambler in the world is the North American X-15, which flies at a speed of 7,274 kilometers per hour, especially with a maximum flight record of 108 kilometers. This aircraft is mainly a rocket-powered test machine that North American Airlines has put a lot of effort into developing. If you fly this plane around the equator, the whole journey is expected to be 40,000 kilometers, which means that it may only take a few hours to circle the earth.

1.Civil aircraft. For this type of aircraft, the flight speed per hour can reach from 800 km to 1000 km. Take the Boeing 737, for example, which can fly at speeds of up to 918 kilometers per hour.

2.Civil aircraft. Among so many civil aircraft, the fastest flight speed is the Concorde, which can reach speeds of 2,600 kilometers per hour, but it should be noted that it is currently grounded.

3.Military aircraft, commonly known as fighter jets, can fly at speeds of up to 1,000 kilometers per hour, and some models can even fly faster.

4., usually an aircraft of this type, can fly at a speed of about 300 kilometers per hour.

In fact, when the plane takes off, the flight speed will be different from when the plane is flying. Generally, an airplane takes off at a speed of 200 kilometers to 400 kilometers per hour. During flight, flight speed is related to many factors, such as aircraft weight and ground temperature.
