Which term is used for objects traveling at Mach 5 or faster? Explained
Items moving at speeds equal to or greater than Mach 5 are classified as hypersonic. The hypersonic category denotes velocities that are five times the speed of sound or beyond, usually surpassing 3,800 miles per hour. Hypersonic advancement is a critical area in cutting-edge aerospace and military technologies, especially concerning the enhancement of hypersonic missiles, aircraft, and spacecraft reentry vehicles. These objects undergo intense aerodynamic heating and necessitate specific materials capable of enduring the severe thermal and pressure environments encountered at such elevated speeds.
