In aerodynamics, a hypersonic speed is one that exceeds five times the speed of sound, often stated as starting at speeds of Mach 5 and above. [1]
Hypersonic flight is flight through the atmosphere below altitudes of about 90 km at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [citation needed]
Sep 27, 2023 · Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and anything Mach 5 or above is considered hypersonic. While the speed of sound changes depending on temperature and altitude, Mach 5 is about 3,800 miles (6,116 km) per hour.
Apr 15, 2022 · What is hypersonic? Describing a vehicle as hypersonic means that it flies much faster than the speed of sound, which is 761 miles per hour (1,225 kilometers per hour) at sea level and 663 mph...
Jan 5, 2024 · NASA made aviation history with the first and second successful flights of a scramjet-powered airplane at hypersonic speeds – speeds greater than Mach 5 or five times the speed of sound.

6 days ago · June 28, 2024 |. The U.S. Navy and U.S. Army recently completed an end-to-end flight test of a hypersonic missile from the Pacific Missile Range Facility, Kauai, HI. The test provided data on the ...
Oct 5, 2016 · The development of new hypersonic (generally faster than Mach 5) capabilities is important for the United States. In the near-term, application of hypersonics research and technologies is likely to be on enhanced defense systems, but this could eventually expand to include improved access to space capabilities that would directly benefit NASA.
Dec 7, 2021 · Our researchers are discovering innovative ways to use aircraft to develop new space capabilities and test space technologies in a relevant environment. Hypersonics research is important both for aeronautics and space research to enable extremely fast travel on Earth as well as for future space exploration.
Jul 20, 2023 · Hypersonics – SACD. Activity Summary. Status: Active. In the field of aerodynamics, hypersonics is generally associated with flight through an atmosphere at speeds in excess of Mach 5, i.e. five times the local speed of sound.
