Web4 okt. 2024 · When you say a vehicle is hypersonic, this means it can fly faster than the speed of sound. The speed of sound amounts to 761 mph (or miles per hour) at sea level, or 1,225 kph (or kilometers per hour), also at sea level. The speed of sound at which a passenger jet would fly, at 35,000 feet of elevation, is 663 mph, or 1,067 kph. High-temperature flow High temperatures due to a manifestation of viscous dissipation cause non-equilibrium chemical flow properties such as vibrational excitation and dissociation and ionization of molecules resulting in convective and radiative heat-flux . Meer weergeven 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. The precise Mach number at which a craft can be said … Meer weergeven While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic … Meer weergeven The categorization of airflow relies on a number of similarity parameters, which allow the simplification of a nearly infinite number of test cases into groups of similarity. For transonic and compressible flow, the Mach and Reynolds numbers alone allow good … Meer weergeven Although "subsonic" and "supersonic" usually refer to speeds below and above the local speed of sound respectively, aerodynamicists often use these terms to refer to … Meer weergeven Hypersonic flow can be approximately separated into a number of regimes.
