In aerodynamics, hypersonic speed refers to speeds much faster than the speed of sound, usually more than approximately Mach 5. [1][2] [3]

We are developing game-changing hypersonic solutions to ensure our customers are always ready for what’s ahead. Traveling at Mach 5 (or a mile a second) and above is the new standard on the …

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 …

Apr 3, 2025 · NASA is working to enable routine, reusable, airbreathing hypersonic flight by conducting fundamental and applied research to enable a broad spectrum of hypersonic systems and missions.

Hypersonic flight is generally defined as speeds at or beyond Mach 5. From an engineering perspective, hypersonics is best understood as a multidisciplinary regime in which fluid mechanics, …

3 days ago · Two revolutionary aerospace technologies collide as GE Aerospace and Lockheed Martin team up to demonstrate a new liquid-fueled rotating-detonation ramjet (RDRJ) designed to close the …

Nov 14, 2025 · Hypersonic flight could one day make long-haul travel as quick as a short movie. Researchers are testing how turbulence behaves at extreme speeds, a critical hurdle for designing …
