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) occur at …

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

May 7, 2021 · At low hypersonic speeds, the molecular bonds vibrate, which changes the magnitude of the forces generated by the air on the aircraft. At higher hypersonic speeds, the molecules break …

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 5 is about 3,800 …

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 air …

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.

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 mastering a …

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

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 enough to …

What is Hypersonic speed? Hypersonic speed is one that exceeds five times the speed of sound, often stated as starting at speeds of Mach 5 and above.
