Characteristics of flow Simulation of hypersonic speed (Mach 5) 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 certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
Hypersonic flight is flight through the atmosphere below altitudes of about 90 km at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [citation needed] Reentry vehicle (RV) after an 8,000-kilometre ...
Jan 5, 2024 · Learn about the X-43A Hyper-X program, which made aviation history with the first and second successful flights of a scramjet-powered airplane at hypersonic speeds. Find out how the X-43A broke the world speed record for an air-breathing vehicle and what challenges and achievements it faced.
Mar 21, 2024 · Hypersonic glide vehicles travel at speeds greater than Mach 5, or approximately 4,000 miles per hour, making them difficult to detect and intercept in time. They can also maneuver and vary ...
Apr 15, 2022 · Learn about the different types of hypersonic missiles, their speed, maneuverability and challenges for defense. Find out why hypersonic weapons are destabilizing and how they can affect nuclear deterrence.
May 7, 2021 · Hypersonic aerodynamics is a special branch of the study of aeronautics. The chief characteristic of hypersonic aerodynamics is that the temperature of the flow around the aircraft is so great that the chemistry of the gas must be considered. At low hypersonic speeds, the molecular bonds vibrate, which changes the magnitude of the forces ...
