High hypersonic
Web16 de set. de 2024 · HCMs are powered by high-speed engines during their entire flight. They are expected to fly at altitudes between 12 and 19 miles. For most HCMs, a rocket would accelerate the missile to Mach 3 or 4, and then the HCM’s own ramjet or supersonic combustion ramjet (scramjet) engine would take over. 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 to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular … Ver mais 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 flows), a hypersonic flow may be characterized by … Ver mais Although "subsonic" and "supersonic" usually refer to speeds below and above the local speed of sound respectively, aerodynamicists … Ver mais Hypersonic flow can be approximately separated into a number of regimes. The selection of these regimes is rough, due to the blurring of the boundaries where a particular effect can … Ver mais The categorization of airflow relies on a number of similarity parameters, which allow the simplification of a nearly infinite number of test … Ver mais • NASA's Guide to Hypersonics • Hypersonics Group at Imperial College • University of Queensland Centre for Hypersonics • High Speed Flow Group at University of New South Wales Ver mais
