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.
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]
Mar 21, 2024 · The US Air Force has tested a hypersonic cruise missile in the Pacific for the first time, in what analysts say is a signal to China that Washington still competes in a weapons arena where many...
Oct 28, 2021 · Hypersonic weapons, and FOBS, could be a concern as they can potentially evade missile shields and early warning systems. Some experts cautioned against hype surrounding missiles such as the one China tested in August.
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.
Apr 15, 2022 · All of the intercontinental ballistic missiles in the world’s nuclear arsenals are hypersonic, reaching about 15,000 mph (24,140 kph), or about 4 miles (6.4 km) per second at their maximum...
Sep 27, 2023 · Hypersonic speed is five times the speed of sound. 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.
Jun 19, 2019 · Capable of traveling at more than 15 times the speed of sound, hypersonic missiles arrive at their targets in a blinding, destructive flash, before any sonic booms or other meaningful warning. So...
May 7, 2021 · Hypersonic aerodynamics is a special branch of the study of aeronautics. The chief characteristic of hypersonic aerodynamics is that the temperature of the flow around the aircraft is so great that the chemistry of the gas must be considered.
Oct 5, 2016 · The HT project focuses on sustaining hypersonic competency for national needs while advancing fundamental hypersonics research. NASA maintains unique specialized facilities and experts who can explore key fundamental research areas for solving the challenges of high-speed flight.
