The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) …

Nov 13, 2025 · New turbulence research supports a long-standing theory and brings the science of hypersonic flight a step closer to reality.

Sonic booms at Mach numbers greater than 5 are exceptionally intense. At hypersonic speeds, the resulting ground-level disturbances, which will likely exceed 130 dB (A), will be strong …

Apr 3, 2025 · In addition to rocket propelled craft travelling at hypersonic speeds, NASA has also studied hypersonic airbreathing propulsion (ramjets and scramjets) and related craft for decades.

Sep 27, 2023 · 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 …

Mar 10, 2025 · Hypersonic speed refers to velocities that exceed Mach 5, significantly faster than the speed of sound. At these speeds, unique aerodynamic challenges arise due to changes in …

Nov 28, 2025 · Hypersonic speed involves entering an entirely new physical regime where the rules of conventional flight no longer apply. Achieving and sustaining this velocity requires …

The speed and maneuverability of hypersonic systems complicate detection and interception, raising questions about the efficacy of existing defense frameworks. Moreover, hypersonic …

Jul 18, 2025 · Hypersonic refers to any object traveling faster than Mach 5, or around 3,800 mph. This is much faster than typical commercial planes, which cruise at about Mach 0.85.

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