See how the hypersonic sled accelerates to 10,620 km/hSeptember 12, 2019
In a second they overcome more than one and a half kilometers
The US Air Force conducted tests on its base of hypersonic sleds, which were dispersed to 10,620 kilometers per hour at a test site.
The video of the tests, which is published on the YouTube channel of the Air Force Test Center, captures the moment the sleigh travels. Even in a four-time slow motion recording, it is impossible to discern anything other than a bright flash.
In the aviation and rocket industries, it is customary to measure speed in Mach numbers — the ratio of flight speed to sound speed. The speed of sound corresponds to Mach 1, the threshold of hypersonic speed – Mach 5. Ultrasonic sleigh managed to disperse to Mach 8.6.
The Holloman Test Site is located in the southwestern United States, in the state of New Mexico. It was built more than half a century ago – a 16-kilometer highway was used to test various ammunition and systems. In the 2000s, it was seriously modernized to conduct hypersonic research.
The founder of Tesla, Elon Musk, has been engaged in creating high-speed automobile tunnels for several years, and two years ago the former technical director of the Hyperloop project showed the concept of a highway on magnetic levitation, on which it will be possible to accelerate to 320 kilometers per hour. The test site should be put into operation in 2021, they will build it in Colorado.
